The purpose of inspection of elevator hoisting machinery is to ensure the safety of daily operation of elevator hoisting machinery. Therefore, relevant staff need to master scientific and effective elevator hoisting machinery related inspection technology to ensure the reliability and safety of elevator hoisting machinery operation.
Our country’s construction engineering industry is developing rapidly, and for residential buildings, shopping malls and other construction projects, especially high-rise or super-high-rise buildings, elevator installation is very important, which is also an important equipment to ensure the access of residents or commercial office personnel. However, in recent years, there have been many safety accidents caused by equipment such as elevators. From a safety point of view, it is necessary to strengthen the daily maintenance and inspection of elevators and lifting equipment. In view of this, the analysis and research around “relevant technology for testing elevator hoisting machinery” has certain value significance.
In order to make the inspection work of elevator and hoisting machinery smooth and orderly, it is necessary to understand the basic principles followed by the inspection work and further prepare for the preliminary inspection work. The summary includes the following points.
1. Principles to be followed when testing elevator hoisting machinery
Based on the analysis of elevator hoisting machinery applied in the current situation, there are more types, different elevator hoisting equipment, there are also differences in design, operating procedures and inspection methods are also different. Therefore, it is necessary to follow the basic principles of rational selection of inspection methods. For the parts where electrical cranes are prone to defects, the application of non-destructive inspection technology can be used to achieve effective inspection. Through the inspection, if cracks, bushing wear and spreader wear do not meet the controllable range, that is, the quality defect limit state is reached, it is necessary to take measures to replace the equipment in time. In addition, it is necessary to strictly implement the inspection standards, strengthen the inspection of the details of the elevator and hoisting machinery, and avoid the occurrence of problems such as missed or false detection.
2. Check the preparatory work of elevator lifting machinery
Lifting machinery is special equipment, and the production process is complicated. Its production cost and production technology are not affordable by ordinary units, not to mention, the country has strict regulations on the control of the production of lifting machinery. In order to ensure the smooth and orderly inspection of elevator hoisting machinery, it is necessary to prepare for the preliminary work of elevator hoisting machinery. On the one hand, complete the search of information files. The manufacturer of elevator hoisting machinery shall provide all the information about elevator hoisting machinery and equipment to the staff of the equipment inspection, so that the inspecting staff can understand the relevant information of the equipment and can inspect the equipment more comprehensively. Relevant inspection staff must maintain a serious and responsible working attitude, and find the corresponding data files for the faults of elevator and hoisting machinery, so that the follow-up maintenance work can be carried out smoothly and effectively. For example: prepare the product qualification certificate, model test report and safety component commissioning manual provided by the corresponding manufacturer of the equipment, prepare the electrical layout drawings and installation drawings provided by the production plant parts, and handle the accidents provided by the manufacturer Documents such as records, reports and self-inspection reports are ready to provide effective data and information support for subsequent maintenance work. On the other hand, strengthen the inspection of the details of elevator lifting equipment. For example, before the inspection of elevator hoisting machinery and equipment, it is very important to clarify the position of the elevator control power supply, and the power box needs to be consistent with the power supply requirements when wiring. During the commissioning and inspection of the equipment, it is necessary to choose to apply a formal power supply and ensure the stability of the power supply voltage; avoid current interference in the vicinity of the power supply box; ensure that the cables are ready to be arranged, and problems such as crossover of the line must be fully avoided. The staff conducting the inspection shall carefully check each part of the elevator hoisting machinery, make sure that the parts of the mechanical equipment are not loose, lubricate the various components, so that they can work normally, there will be no problems during the operation, and prevent the occurrence of elevator accidents . In addition, if safety problems are found during the inspection, they must be recorded in detail in order to provide effective record support for subsequent maintenance work.
3. Visual inspection technology
The visual inspection is also called visual inspection, which is to assist the inspector to understand the safety of the elevator and whether its quality meets the requirements. The visual inspection requires the inspector to inspect the entire structure of the elevator. Because of the overall understanding of the elevator, the inspector cannot carry out random inspections or general inspections of the elevator parts. The inspector needs to carefully examine each part of the elevator Check in order to grasp the overall situation of the elevator. The visual inspection needs to inspect the mechanical parts in the elevator. The size and quality of the metal structure and the quality of the mechanical devices all need to be inspected by the inspectors to make them meet the equipment requirements. Based on the overall analysis of the inspection work of elevator hoisting machinery, for visual inspection technology, it is a more traditional inspection technology method. The application of this technical method is mainly to judge the operation of elevator hoisting machinery. Find out the obvious fault problems, and then judge whether further maintenance work is needed. However, the visual inspection technology also has its own advantages, that is, the adoption of visual inspection technology does not require the help of other related inspection system equipment, and will not be restricted by time and place. It can achieve inspection anytime and anywhere, and can quickly find some major The failure can avoid the further development of the failure. However, for visual inspection methods, usually only the surface of elevator hoisting machinery equipment can be inspected, while for the internal conditions of elevator hoisting machinery equipment, it is difficult to perform effective inspection. Therefore, it is recommended that during the inspection of elevator hoisting machinery and equipment, first of all, through the application of visual inspection technology methods, further cooperate with other inspection technologies to ensure the effectiveness and scientificity of inspection. In other words, the visual detection technology can be used as an auxiliary detection technology. For example, use visual inspection technology to observe the shape of elevator lifting equipment, observe whether the parts of the key parts of the equipment are deformed by the influence of external forces, observe whether the parts have deep friction problems, and observe the safety Whether the device is in normal operation, etc. Through visual inspection at these levels, combined with the above-mentioned ray detection technology and penetration detection technology, the problem of potential safety hazards will be further clarified and resolved in time to ensure the elevator Hoisting machinery operates normally and safely.
In summary, in order to ensure the reliability and safety of the operation of elevator lifting equipment, it is very important to strengthen the inspection of elevator lifting equipment. Therefore, it is necessary to master some scientific and effective elevator lifting machinery inspection technology. Before the inspection work is carried out, understand the basic principles to be followed for the inspection of elevator hoisting machinery and equipment, and make further preparations for the inspection of elevator hoisting equipment, and then, in the process of actual inspection work, reasonably apply radiographic testing techniques , Penetration testing technology, visual testing technology and metal magnetic memory testing methods, etc. It is believed that in the inspection work of elevator hoisting machinery and equipment, if these detection techniques are used reasonably and scientifically, the quality and effect of the inspection work will be effectively improved, thereby providing the necessary technical support for the further maintenance work of elevator hoisting machinery and equipment.
The car body frame is the basis of all parts installation. The car has chassis, and there are so many spare parts in the chassis, such as engine, gearbox, wheels, suspension, brake, etc. Most of the cars adopt the load-bearing body. The girder of the load-bearing body is integrated with the car shell, which makes the body lighter and more comfortable. In terms of chassis, there are two front and rear sub-frames, so the front suspension of engine transmission of horizontal engine front drive vehicle is fixed on the front sub-frame, and the rear sub-frame is fixed to the rear suspension. If it is a rear drive vehicle with longitudinal engine, only the engine and suspension system are fixed on the front sub-frame, and there are rear suspension and differential on the rear sub-frame. There are many driving forms of automobile, such as front front front drive, front four-wheel drive, front rear drive, middle rear drive, middle four-wheel drive, rear four-wheel drive, rear rear rear drive, etc. Most family cars use front drive, so the front drive is generally transverse engine. The front and rear drive are usually longitudinal engines. Some front four-wheel drive vehicles use a transverse engine, while some front four-wheel drive vehicles use a longitudinal engine. The layout of the engine is related to the driving mode. The front-end drive vehicle will have under-steer in fast cornering, while the front rear drive will have over-steer in fast cornering. Automobile suspension is divided into independent suspension and non independent suspension. Torsion beam is commonly used in non independent suspension, while McPherson strut type, double wishbone type and multi-link type are commonly used in independent suspension.
Novice for car, Please pay attention below
As a novice, the minimum knowledge of cars is necessary. In driving school, you may learn a little knowledge, and do not fully understand the car, but when you leave the coach and drive on the road, you must know some basic things, such as when you drive out and find that there is no oil, do you know the location of the mailbox, and when you need to put things Do you know how to open the trunk? The coach has not taught you these basic things. Let’s learn them together. First of all, when your car has no gas, it means you need to refuel. Secondly, the use of light is also very important, especially at night, the role of light is even more important. When you use the light, the light is on the left side of the steering wheel. When you use the light, you should first turn the light on. When you turn up the low beam light, press the high beam light. Depending on the operation of the car, the design of the high and low beam lights of some cars is just the opposite.
The second is the filling of glass water. This sign is similar to a fan-shaped pattern, and then there are two lines for spraying water. If the light is on, it means that your glass water is insufficient. You need to add glass water manually, however before adding glass water, you must confirm its position.
Finally, the inspection of engine oil, which also plays an important role in the whole automobile participation, is the blood of human if the engine is human body. We know that when the car reaches a certain mileage, we need to change the oil in order to make the car run better. There is a ruler for oil inspection. When the oil level is between the upper limit and the lower limit of the gauge, it is normal. These are the common knowledge of the car that you must know as a novice. When you look at the above points, you don’t need to worry about your car.
Feed additives refer to small or trace substances added in the process of feed production, processing and use. The amount of feed additives is small but the effect is significant. Feed additives are inevitable raw materials used in the modern feed industry, and have obvious effects on strengthening the nutritional value of basic feeds, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of animal products.
Introduction of feed additives
Feed additives are divided into microbial feed additives and Chinese herbal medicine feed additives. Among them, the microbial feed additive is a microbial product that replaces or balances one or more bacterial systems in animal ecosystems.
Main type of feed additives
1. Bile acid
Longchang bile acid is the main active ingredient of bile. In the circulation of liver and intestines, it combines with fatty acids, emulsifies fats, and forms fat-soluble complexes with fatty acids, allowing fatty acids to be absorbed through the membrane. Digestion and absorption have been completed. All biochemical reactions in the body, especially enzymatic reactions, are carried out in an aqueous solution, so the fat can only enter the fatty acid digestion process if it is emulsified and forms a fatty acid-emulsifier complex. Because the hepatointestinal circulation is not a completely closed circulation, the lack of endogenous emulsifier secretion becomes the biggest factor affecting the digestion and absorption of fat. Feed grade bile acid is a high-performance fat emulsifier. It can improve the activity of endogenous emulsifier, make up for the deficiency of endogenous emulsifier secretion, and thus release the potential energy of feed. It can promote the digestion and absorption of fat, protect the liver and gallbladder, improve the health of livestock and poultry, and increase the utilization rate of feed.
Including citric acid, fumaric acid, lactic acid, acetic acid, hydrochloric acid, phosphoric acid and compound acidifier, etc. Adding the right amount of acidification to the pig diet can significantly increase the daily weight gain of the pig and reduce the feeding cost.
3. Calcium formate
As a feed additive, calcium formate is particularly suitable for weaned piglets. It can affect the growth of intestinal microbes, activate pepsinogen, increase the energy utilization of natural metabolites, improve feed conversion rate, prevent diarrhea and diarrhea, and improve the survival rate of piglets. And the rate of daily weight gain. At the same time, feed grade calcium formate also has the effect of preventing mildew and keeping fresh. Adding calcium formate to the feed will release a small amount of formic acid in the animal body, which will reduce the PH value of the gastrointestinal tract, and has a buffering effect, which is conducive to the stability of the PH value in the gastrointestinal tract, thereby inhibiting the reproduction of harmful bacteria and promoting the growth of beneficial microorganisms. For example, the growth of Lactobacillus can cover the intestinal mucosa from toxin invasion, so as to control and prevent the diarrhoea and diarrhea related to bacteria from occurring. The added amount is generally 1-1.5%. Calcium formate is used as an acidulant. Compared with citric acid, it does not deliquesce in the process of feed production. It has good fluidity and a neutral PH value. It does not cause equipment corrosion. Adding it directly to the feed can prevent nutrients such as vitamins and amino acids. Destruction is an ideal feed acidifier.
Main Application of feed additives
The digestive tract of chickens is relatively short, and the intestinal mucosal barrier is fragile. Under intensive aquaculture conditions, it is more susceptible to harmful microorganisms than long digestive tract animals, resulting in various diseases. The use of feed additives is one of the effective means to prevent intestinal diseases and improve the production performance of broilers and laying hens. The growth rate of broilers is fast, and it is greatly affected by the environment in intensive production. The application of feed additives can improve the balance of intestinal flora, reduce the incidence and mortality of intestinal diseases, increase the weight of slaughter, reduce the ratio of feed to meat, and can reduce Ammonia, hydrogen sulfide and other harmful gas emissions in the chicken house improve product quality. The application of feed additives in laying hen breeding, in addition to preventing diseases, improving production performance and feed remuneration, also has an improving effect on egg quality. Studies have shown that adding feed additives to laying hen diets can increase the Hastelloy unit of the egg, reduce the cholesterol content of the egg, and has the effects of improving the thickness of the egg shell and reducing soft-shell eggs.
Current research and application shows that feed additives have achieved good application results in the breeding of piglets, sows and fattening pigs. Adding feed additives to piglet diets can promote piglet intestinal development, improve intestinal health, reduce diarrhea rate, increase piglet growth rate and feed conversion rate. For suckling piglets, the addition of feed additives helps to establish the predominant flora of probiotics; for weaned piglets, it can improve the adverse effects of diarrhea and growth inhibition due to factors such as their own digestive enzyme secretion and dietary antigenicity. Studies have shown that the use of feed additives in sow diets can improve intestinal health, improve sow immunity and reproductive performance. After adding feed additives, it can improve the ability to regulate the balance of bacteria in the gastrointestinal tract, increase the intake of sows during lactation, suppress weight loss, increase the fat and protein content of sow milk, improve the survival rate of weaned piglets and weaned piglets body weight. Adding feed additives to fattening pig diets can increase feed intake and feed conversion rate, improve health, shorten fattening periods, and improve quality and reduce environmental pollution. Studies have shown that the addition of feed additives can reduce the diarrhea rate of fattening pigs, improve immunity, increase feed intake and feed digestibility, thereby improving diet utilization and reducing feed-to-meat ratio. In addition, feed additives have a certain promoting effect on increasing intramuscular fat and increasing the content of essential fatty acids, which can improve the quality of pork.
3. Aquatic products
The application of feed additives in aquatic products is reflected in two aspects: bait and water purification. Feed additives can improve the micro-ecological balance of aquatic animals, promote growth and development, play a role in preventing diseases and improving production performance. Probiotics can be colonized in the intestines of fish, promote the growth and development of fish, and improve disease resistance. Feed additives can reduce the incidence of shrimp and increase survival rate and yield. Feed additives can be used as immune stimulants and adjuvants for aquatic animals, promote the development of immune organs, improve humoral immunity, and improve immune function. This effect has been verified in a variety of aquatic animals. Photosynthetic bacteria and nitrifying bacteria in feed additives can consume organic matter in water, remove ammonia nitrogen, hydrogen sulfide, nitrous nitrogen, etc. It is an important beneficial microorganism currently used to improve the aquaculture environment. It is used in aquatic animals such as shrimp and flounder. Good application results are obtained in breeding.
The steel strand is a steel product composed of several steel wires. According to the needs, the galvanized layer, zinc aluminum alloy layer, aluminum coating, copper coating and epoxy resin coating can be added on the surface of carbon steel. Steel strand can be divided into: prestressed, unbonded, galvanized steel strand, etc. This paper only introduces the prestressed steel strand with the largest market circulation and consumption.
Structure and application of steel strand
Prestressed steel strand is a stranded steel cable composed of 2, 3, 7 or 19 high-strength steel wires, which has been stress relieved (stabilized). The main features are high strength and good relaxation performance. In addition, it is relatively straight when it is unfolded and suitable for prestressed concrete or similar purposes. It is widely used in infrastructure projects such as high-speed railway construction, expressway and national and provincial highway bridge. China’s prestressed steel strand industry originated in the 1960s, began to introduce western technology in 1988, and began to develop rapidly after 1995, mainly due to the sustained growth of China’s economy and the country’s policy of continuous investment in infrastructure. Now China has become the largest prestressed steel strand consumer market in the world.
Galvanized steel strand is usually used for messenger wire, guy wire, core wire or strength member, etc. it can also be used as earth wire / ground wire of overhead power transmission, barrier cable on both sides of highway or structural cable in building structure. The common prestressed steel strand in prestressed steel strand is uncoated steel strand for prestressed concrete, also galvanized, which is commonly used in bridge, construction, water conservancy, energy and geotechnical engineering, unbonded steel strand or monostrand is commonly used in floor and foundation engineering, etc.
The manufacturing process is divided into single wire manufacturing and stranded wire manufacturing. The (cold) drawing technology is used in the production of single wire. According to different materials of the product, it can be high carbon steel wire rod, stainless steel wire rod or medium and low carbon steel wire rod. If galvanizing is required, electroplating or hot plating shall be carried out on the single wire. In the process of strand manufacturing, multiple steel wires are twisted into products by a strander, and the prestressed steel strand needs to be stabilized continuously after forming. The final product is generally collected on the I-shaped wheel or completed as a reel less
Steel strand China market
At present, the production bases of steel strand are mainly in Tianjin, Jiangsu, Hebei and Henan, which account for 70% of the total output of the country. Tianjin has obvious location advantages, and the logistics in the center of the North-South channel is more convenient, which can easily radiate Beijing, Tianjin, Hebei, Shanxi, Inner Mongolia and northeast provinces. Due to the development of Tianjin strand industry cluster, B steel production of iron and steel enterprises in the region is driven, and Rongcheng steel and Aosen steel provide sufficient raw material supply in the region. Manufacturers along the Yangtze River mainly radiate to Jiangsu, Zhejiang, Shanghai, Fujian and Guangdong, benefiting from the developed inland water network transportation and low freight. There are Shagang, Yonggang, Wuhu Xinxing and other manufacturers in the area as raw material suppliers with sufficient supply.
According to Mysteel’s statistics, there are 54 sample steel strand manufacturers in total, with a total output of 5.6756 million tons in 2017, of which nearly 50% are concentrated in North China; the second is East China, accounting for 25% and central China, accounting for 12%; the third is Tianjin, with a total of 20 sample steel strand manufacturers, with a regional output of 2.37 million tons in 2017, ranking first in China, accounting for 42%; and Next, Jiangsu accounted for 12% and Hebei for 8%. Overall, the region is highly concentrated in North China, followed by East China, but with the construction of national projects, the southwest and northwest regions will be the key development areas in the future.
Future market of strand steel
With the continuous breakthrough of technical barriers in China’s steel strand industry and the involvement of a large number of private capital, the proportion of private enterprises continues to rise. In 2018, the industry expects that China’s new steel strand capacity will be about 400000, and the effective capacity will reach 6 million at the end of the year. In the future, the competition in the industry market will be particularly fierce, in which the large manufacturers and brand manufacturers occupy the high-end market through their own brand advantages and long-term customer resource advantages established through cooperation, while some private manufacturers adopt regional sales mode and low-cost cash sales to compete, resulting in the increase of many steel strand manufacturers’ output and the decrease of profits, or even losses. Therefore, the future market urgently needs the supervision and coordination mechanism.

Both of them has their pros and cons. In this article, we are going to take a look at the difference between airbrush makeup and others.
Airbrush Makeup Vs. Regular Makeup
This type of makeup is applied with an air compressor and airbrush stylus. The air compressor is like the one used to apply spray tans. Typically, it’s applied on a small scale in the form of mist. So, the product should be thinner than the regular foundation.
Although air brush makeup is thinner, it’s a great choice to cover flaws and imperfections. And you will still look natural as the same time your skin will still be able to breathe. In other words, with this type of makeup kit, your skin will look natural and professional.
Traditional makeup is the regular makeup that most people wear. It refers to products in the form of powder, cream, or liquid. They are applied with the help of fingers, sponges, or brushes. Typically, the products are thicker but you can choose from a lot of variations.
The Benefits Of Airbrush Makeup

The occasional online buyers searching to purchase auto parts cheaply will mostly likely first consider, “Used parts are cheaper.” What’s sad about this thought is that this potential buyer probably doesn’t know about the auto part’s previous owner; under what circumstance and from which country it ended up at the store, and the potential it might put buyers safety at risk. Certainly, “used” means “affordable,” however it better safe than sorry.
My reasons are as follows.
1. Used auto parts are usually recovered from abandoned, or crashed automobiles, and researches indicate that these components demand the highest probability of replacement and repair. Unintentionally equipping a faulty part from a destroyed vehicle may not just affect reliability. Based on your auto part, your safety, performance and other parameters could be changed and go unexpected.
2. It’s almost impossible to have used auto parts adequately tested. Almost no agencies, government or otherwise, supervise used auto part inspection. While some do perform, finding out a middleman is likely an effort you’ll should resist to buy. Instead, you can concentrate your goal on looking for affordable auto parts instead; they are always brand new, properly tested and easy to use.
3. The most popular used auto parts are also the most safety vulnerable. The most cost prohibitive auto parts, are those that are the most adequately inspected at reduced prices. These components are generally mini, critical parts. Replacing them with displaced, unchecked, reconfigured or recycled parts pose the greatest danger to your life, given their significance to the over all reliability of your automobile. For instance, even though a cheap air conditioner can conveniently be bought second handed, these are usually not costly anyway. A universal rule of thumb is that the cheaper the part, the more danger there is revealed by discounted service.
4. Junk yard don’t guarantee functionality. While suitable for external parts like windshield and doors, internal parts can shift in functionality from yard to yard and inspecting safety just isn’t a solution. Car accidents resulting from problematic parts waste more money than conveniently buying new parts at a more expensive rate.
So what’s the possible solution? Purchase new auto parts at discount prices.
Here are a few ways of discovering cheap automobile components online without sacrificing reliability or durability:
Check out online discount retailers
By reducing prepayment and dropping profit margins, online auto part retailers can lower prices on unused auto parts in order to stay popular. These retailers manage what are labeled “discount stores.” Even if an online store isn’t named after “discount,” if the price of new parts is reasonable, it’s an easy win that “discount” in this situation doesn’t equal dangerous.
Discount sellers generally operate on the internet because doing so drastically reduces cost, letting them to sell reliable auto parts at low prices.
Look for wholesalers
Many web stores run as dealers for the oversea manufacturer, and these stores will raise prices for profit. You can bypass web dealers as you wish when searching for discount automobile parts by Google auto parts wholesalers on the internet. The majority trustworthy wholesalers will have a website, showing you series of product, cheaper prices, ease of searching, and quick shipping. Make sure to exercise precaution before paying. Consult with customer service directly if available.
