As one of the widely used industrial machines, screw air compressor needs to pay attention to what aspects of problems during operation? The problems can be explained clearly from the five main aspects. Although they are not comprehensive enough, the more common problems are mentioned.

1. Screw air compressor cannot be started

The possibility of causing 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. 2、 The relay protecting the machine has lost its effect. 3、 The start button is not in good contact. This problem is not very common. Unless the screw air compressor is really a cheap machine, it will not occur. Even if it does, it is very easy to solve it. 4、 The supply voltage of the screw air compressor is too low. 5、 The motor of the machine has problems, which is more complicated. Generally, the air compressor manufacturers with strong technical strength have a low probability of such problems.

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

There are four aspects to check whether there is a problem. The first is the intake valve, the second is the excessive supply of air, the third is whether the air filter plug of the air compressor is blocked by foreign matters, and the last is to check whether the oil-gas separation core is blocked. Generally, the above four problems cause this situation. However, newly purchased air compressors generally do not have such problems. Generally, air compressors that have been used for many years will have such problems.

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, it is critical whether the air contains too much oil. There are many reasons for this problem. There are mainly six reasons. First, the oil and gas are too high. Second, the oil return pipe filter or orifice is blocked. Third, the oil and gas separation core is damaged. Then, the oil regulating system of the air compressor leaks oil. Another possible reason is that the gas production pressure of the air compressor is too low. Finally, the problem of lubricating oil in the province, If there is too much foam in the lubricating oil used by the screw air compressor, it will also cause such problems.

4. The exhaust temperature of the machine is too high

Generally speaking, the temperature is higher than 150 degrees, and the main causes of this kind of situation are that the ambient temperature of the screw air compressor is too high or the temperature control valve can not work normally. There is also insufficient oil supply and 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 also problems with the cooling fan and thermal resistance failure. If the machine is well maintained, such problems are relatively rare.

5. The air compressor cannot be unloaded

In general, you can check whether the intake valve works normally, and also check whether the pressure sensor works normally. In fact, the screw air compressor is a bit like an automobile. If it is well maintained, its working life will be long, and the possibility of problems will be even lower. Most of the problems of the screw air compressor are caused by improper maintenance or wrong methods.
