As one of the widely used industrial machines, screw air compressors need to pay attention to what issues when operating. The problems can be clearly explained in the five most important aspects. Although not comprehensive enough, more common problems are mentioned.
1. Screw air compressor can not start to cause this problem is more likely, but experienced engineers will generally consider the following aspects: First, the fuse is burned out, this is a more common problem. Second, the relay protecting the machine has lost its effect. Third, the poor start button contact, this problem is not common, because now screw air compressor, unless it is really a cheap machine to buy cheap, otherwise generally does not appear such a problem, even if there is also Good solution. Fourth, screw air compressor supply voltage is too low. Fifth, the motor of the machine has a problem. This is more complicated. The general compressor manufacturers with relatively strong technical strength have a lower probability of such problems.
2. The exhaust pressure of the screw air compressor is too low to check if there are problems in four aspects. The first is the intake valve, the second is that the supply of air is excessive, and the third is whether the air filter plug of the air compressor is Blocked by foreign matter, the final step is to check whether the oil and gas separation core is blocked. This is usually caused by the above four problems. However, newly purchased air compressors generally do not have such problems. Generally, air compressors used for many years will have such problems.
3. The gas content of the screw air compressor is too high. For companies that focus on 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 are too high. Second, the oil return pipe filter or the orifice is blocked. The third is the damage of the oil and gas separation core. Then there is the oil leakage in the air compressor's oil regulation system. The possible reason is that the air compressor's gas pressure is too low. Finally, it is the problem of lube oil in this province. If the screw air compressor uses the foam of the oil Too much will also cause such problems.
4. Exhaust temperature of the machine is too high. Generally speaking, the temperature is too high is more than 150 degrees, and the screw air compressor caused this kind of situation is mainly the ambient temperature of the machine is too high or the temperature control valve can not work, There is insufficient oil supply. The oil cooler has not been cleaned for a long period of time. Sometimes the obstruction of the oil filter can also cause this situation. There are problems with the cooling fan, thermal resistance failure, and so on. If it is said that the machines are well maintained, such problems are still relatively rare.
5. If the air compressor cannot be empty, it can be checked from the normal operation of the air intake valve. It is also possible to check if the pressure sensor is working properly. In fact, screw air compressor is a bit like a car, if the maintenance is good, its working life will be factory, and the possibility of problems is even lower, and many times the screw air compressor problems are mostly due to improper maintenance or methods Caused by mistakes.
