Air compressor is "air compressor". Generally speaking, it is used to compress air. It is the main part of the air source device. It is the device that converts the mechanical energy of the prime mover (usually the motor) into the gas pressure energy. It is the pressure generating device of compressed air. There are many kinds of air compressor, according to the working principle is divided into volume compressor and speed compressor. The following Shandong air compressor small series to introduce the cause of air compressor overload.

1、主机或电机堵转或轴承损坏。解决方案：需要更换对应零件。

1. The main engine or motor is locked or the bearing is damaged. Solution: the corresponding parts need to be replaced.

2、电源电压过低。解决方案：如果是低压线路过长，功率因数偏低，可以通过在低压加装电力电容器的方法，提高功率因数，来提高受电端电压。

2. The supply voltage is too low. Solution: if the low-voltage line is too long and the power factor is low, the power factor can be improved by adding power capacitor to the low-voltage line to improve the voltage at the receiving end.

3、缺相运行。解决方法：应即时停运和严禁起动，否则将烧毁电动机。

3. Open phase operation. Solution: shut down immediately and do not start, otherwise the motor will be burned.

工作时，空气经过自洁式空气过滤器被吸入，通过PLC自动清洗过滤器，空气在经过进口导叶自动调节后进入一级压缩，经一级压缩后的气体温度较高，然后进入中间冷却器进行冷却（水走管内，气走管外，中冷器的水流量要求为110m/h）之后进入二级压缩系统。

When working, the air is sucked through the self-cleaning air filter, and the filter is automatically cleaned by PLC. The air enters the first stage compression after the automatic adjustment of the inlet guide vane. The gas temperature after the first stage compression is higher, and then enters the intercooler for cooling (inside the water pipe, outside the gas pipe, and the water flow of the intercooler is required to be 110m / h), and then enters the second stage compression system.

为避免系统中的气体倒入压缩腔内（避免带压起动）在压缩机的排气管道安装有一只悬挂全启式止回阀，压缩机排出的气体推开止回阀进入排气消声器，然后进入一级后冷器，二级后冷器，再进入排气主管道。

In order to prevent the gas in the system from pouring into the compression chamber (to avoid starting under pressure), a suspended full open check valve is installed in the exhaust pipe of the compressor. The gas discharged from the compressor pushes the check valve to enter the exhaust muffler, then enters the primary aftercooler, the secondary aftercooler, and then enters the main exhaust pipe.
