Common problems of screw air compressor

Screw air compressor as one of the most widely used industrial machines, in the operation of the need to pay attention to what aspects of the problem from the main five aspects can be made clear, although not comprehensive enough, but the more common problems are mentioned.

1. Screw air compressor cannot be started

there are many possibilities for causing this problem, but experienced engineers generally consider the problem from the following aspects: First, whether the fuse is burned out, this is a relatively common problem. Second, the relay that protects the machine loses its effect. After intelligent testing, to packaging delivery, service and feedback.

Air compressor is a kind of general-purpose mechanical equipment in industrial production, which is widely used in petroleum, chemical industry, electric power metallurgy, mining, construction, light industry, pharmaceutical, civil and national defense departments, and occupies an important place in the national economy...

Third, the start button contact is not good, this problem is not very common, because now the screw air compressor, unless it is really cheap and buy a very low price of the machine, otherwise generally will not appear such a problem, even if there is also a good solution. Fourth, the screw air compressor supply voltage is too low. Fifth, the machine's motor has a problem, which is more complicated. The probability of such problems in air compressor manufacturers with relatively strong technical strength is relatively low.

2. The exhaust pressure of the screw air compressor is too low

you can check whether there is a problem from four aspects, one is the intake valve, the second is the air supply is excessive, the third is whether the air filter plug of the air compressor is blocked by foreign matter, and then check whether the oil and gas separation core is blocked. Generally, the above four problems are caused by this situation. Third, the existing product lines of many compressor companies are very scattered, resulting in serious product homogeneity on the market.

Oil-free air compressor maintenance knowledge oil-free air compressor can work without adding any lubricating oil. The exhaust gas does not contain oil, thus eliminating the troublesome environmental protection period and social benefits of oil pollution to natural gas facilities and two sub-products. It is more convenient to use and maintain.

However, the newly bought air compressor generally does not have such a problem, generally used for many years of air compressor will have such a problem.

3. The oil content of the gas produced by the screw air compressor is too high

for those enterprises that pay great attention to air quality, whether the air contains too much oil is very critical. There are many reasons for this problem. There are mainly six reasons. One is that the oil and gas are too high, the second is that the oil return pipe filter or orifice is blocked, the third is that the oil and gas separation core is damaged, and the oil adjustment system of the air compressor leaks oil. Another possible reason is that the air pressure of the air compressor is too low, and then the problem of the province of lubricating oil, if the foam of the lubricating oil used in the screw air compressor is too much, it will also cause such a problem. As a strategic Suzhou industrial enterprise participating in the exhibition, Fei Zhong, general manager of the president work department of Poly GCL Energy Holdings Co., Ltd., one of the domestic photovoltaic enterprises, said in an interview with reporters that the photovoltaic industry is a policy-oriented and market-oriented industry. To a certain extent, the promotion of policy orientation will be greater.

Includes the compressor itself, compressed air storage and compressed air distribution piping. This means that the compressed air produced by an oil-free compressor is not necessarily pollution-free, although the use of air treatment products can help reduce pollution to the desired level.

4. The exhaust temperature of the machine is too high

generally speaking, the temperature is too high to exceed 150 degrees, and the main causes of this kind of situation in the screw air compressor are that the ambient temperature of the machine is too high or the temperature control valve is working impermanently, there is insufficient oil supply, the oil cooler has not been cleaned for a long time, sometimes the blockage of the oil filter will also cause this situation, there are problems with the cooling fan, thermal resistance failure, etc. If the machine is well maintained, such problems are still relatively rare. Not only through field trips, but also through data analysis.

5. The air compressor cannot be empty

in general, you can check whether the intake valve is working properly, and you can also check whether the pressure sensor is working properly. In fact, the screw air compressor is a bit like a car. If it is well maintained, its working life will be reduced, and the possibility of problems will be even lower. Most of the time, the screw air compressor has problems due to improper maintenance or methods. Caused by errors. At present, there is an air compressor with an exhaust pressure of 0.6MP in the society, which is unreasonable from the perspective of use, because the pressure margin is too small for the wind-moving tools, and the gas transmission distance is too small...
