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. The main engine or motor is locked or the bearing is damaged. Solution: the corresponding parts need to be replaced.
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. Open phase operation. Solution: shut down immediately and do not start, otherwise the motor will be burned.
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.
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.
