As one of the most widely used industrial machines, screw air compressors need to pay attention to what problems should be paid during operation? From the five main aspects, you can make the problem clear, although not comprehensive, but the more common problems are mentioned.
1, screw air compressor can not start
There are many possibilities for this problem, but experienced engineers generally consider the following aspects: First, whether the fuse is burnt out, this is a relatively common problem. Second, the relay that protects the machine has lost its effect. Third, the start button is not well connected, this problem is not very common, because now the screw air compressor, unless it is really a cheaper to buy a very low price machine, otherwise it is generally not such a problem, even if it appears Very good solution. Fourth, the supply voltage of the screw air compressor is too low. Fifth, the motor of the machine has a problem, which is more complicated. The air compressor manufacturer with relatively strong technical strength has a lower probability of such problems.
2. The exhaust pressure of the screw air compressor is too low.
It can be checked from four aspects whether there is a problem, the first is the intake Valve, the second is the supply of air is excessive, and the third is whether the air filter plug of the air compressor is blocked by foreign matter, and finally the oil and gas separation is checked. Whether the core is blocked or not, generally the above four problems are caused by this situation. However, the 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 gas content of the gas produced by the screw air compressor is too high.
For companies that are very concerned about air quality, it is critical that the air contains too much oil. There are many reasons for this problem. There are six main reasons. First, the oil and gas is too high. Second, the return pipe filter or orifice is blocked. The third is that the oil and gas separation core is damaged. Then there is oil leakage in the oil control system of the air compressor. The possible reason is that the gas pressure of the air compressor is too low. Finally, the problem of the lubricant is the problem of the province. If the screw air compressor uses the foam of the lubricating oil. Too much will also cause such problems.
4, the machine's exhaust temperature is too high
Generally speaking, the temperature is too high is more than 150 degrees, and the screw air compressor is mainly caused by the fact that the ambient temperature of the machine is too high or the temperature control valve is not working properly, and the oil supply is insufficient. The oil cooler has not been cleaned for a long time. Sometimes the oil filter blockage will also cause this situation, and there is a problem with the cooling fan, the thermal resistance is invalid, and so on. If the machine is well maintained, such problems are less likely to occur.
5, air compressor can not empty car
In general, it is possible to check whether the operation of the intake valve is normal or not, and check whether the pressure sensor is working normally. In fact, the screw air compressor is a bit like a car. If it is well maintained, its working life will be factory, and the possibility of problems will be even lower. In many cases, the screw air compressor has problems mostly due to improper maintenance or methods. Caused by mistakes.
