The fuel injection twin screw air compressor is a common kind of air compressor. The failure of the screw type air compressor will affect the life of the air compressor and the personal safety of the operator. Therefore, it is very important to understand the fault of the screw type air compressor in the industrial production. In the process of using the fuel injection twin screw air compressor, we need to check the air compressor regularly and eliminate the failure. The following is a simple introduction to the common faults and solutions of the following screw air compressor.

1. screw type air compressor failure phenomenon: the large current of the unit

The main performance is: the voltage is too low, the connection is loose, the unit pressure exceeds the rated pressure, the oil separation core is blocked, the contactor failure, the main engine fault, the main motor fault;

Failure phenomenon of 2. screw air compressor: large fuel consumption or large volume of compressed air.

The reason for this failure is because the cooling dose is too much, the correct position should be observed when the unit is loaded, and the oil level should not be more than half of the oil level, and the blockage of the oil pipe will also cause the screw type air compressor fault. The installation of the back oil pipe will result in the excessive oil consumption of the screw compressor; the exhaust pressure of the unit is too low; oil separation is too low; oil separation is separated. The core breakage will lead to the breakdown of the screw air compressor, the separation of the inner baffle of the cylinder body, the deterioration or overdue use of the coolant.

3. screw type air compressor failure phenomenon: low pressure of unit

The cause of this failure is that the actual gas volume is greater than the output of the unit; the screw type air compressor outgassing, the intake valve failure (can not be closed when loading); the transmission system is not normal, the ambient temperature is too high, the air filter is blocked, the load solenoid valve (1SV) fault, the minimum pressure valve card death, the leakage of the user pipe network, pressure sensor, pressure meter The failure of screw type air compressor such as pressure switch can cause low pressure on the unit, and pressure sensor or pressure gauge can enter the hose to leak.

4. screw air compressor fault phenomenon: fan motor overload.

Fan deformation, fan motor failure, fan motor thermal relay failure (aging), loose connection, cooler blockage, large exhaust resistance.
