Five Common Problems of Air Compressor

1. Screw air compressor cannot be started

air compressor can not start the possibility of this problem is more than the price, but experienced engineers will generally consider the problem from the following aspects:

first, whether the fuse is burnt out is a common problem.

Second, the relay that protects the machine loses its effect.

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. Exhaust pressure of screw air compressor is too low

***, intake valve,

second, the excess supply of air

third, whether the air filter plug of the air compressor is blocked by foreign matter

fourth, check whether the oil and gas separation core is blocked

this is generally caused by the above four problems. 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. And there are many reasons for this problem,

there are six main reasons:

***, oil and gas is too high

second, the return pipe filter or orifice is blocked

third, the oil and gas separation core is damaged

fourth, the oil adjustment system of the air compressor has leaked oil.

Fifth, the air pressure of the air compressor is too low

sixth, the problem of lubricating oil in the province, if the screw air compressor uses too much lubricating oil foam, it will also cause such a problem.

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 cannot work normally, and 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, or the cooling fan has problems, thermal resistance failure, etc. As long as the usual attention to the maintenance of the machine, this kind of problem is still relatively rare.

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. Screw air compressor is the same as a car. As long as it is well maintained, its working life will be extended, and the possibility of problems will be even lower. Most of the time, screw air compressor problems are mostly caused by improper maintenance or wrong methods.
