The reasons for the motor damage of the Dimethyl ether compressor are multi-faceted and comprehensive, not only common to other motor power equipment, but also related to the failure factors of the DME compressor itself in the specific operation. The analysis mainly includes the following points:

Dimethyl ether compressor for sale near me 1. The reliability and sensitivity of the automatic air pressure switch. Usually, the start and stop of the Dimethyl ether compressor are automatically controlled by the air pressure automatic switch (air pressure relay) that directly drives the communication contactor. Most of the pneumatic automatic switches of the Dimethyl ether compressor use a mechanical structure, which uses the spring contraction to release energy to operate the contacts. It may be due to the congenital deficiency of the automatic air pressure switch, or the influence of different reasons such as improper adjustment and machine vibration. During the air pressure control process of the Dimethyl ether compressor, the abnormal action phenomenon often occurs: when the air pressure is automatically switched, the action is refused, so that the motor of the Dimethyl ether compressor cannot run normally, and the air pressure continues to rise, causing the motor to run overloaded, which may cause failure and blockage in severe cases.
2. The automatic exhaust valve is faulty. Dimethyl ether compressors generally do not have an automatic exhaust. When the air pressure reaches the set pressure of the Dimethyl ether compressor, it will automatically exhaust and depressurize after shutdown, and preset the next no-load start. After the exhaust valve fails, the air pressure in the cylinder of the Dimethyl ether compressor cannot be released, which means that the motor starts under load, which may cause difficulty in starting or stall failure.
3. Power transmission suddenly stops during operation. Automatic control of Dimethyl ether compressor in case of a sudden stop of power transmission (such as the conversion of mains and self-contained power). Since the cylinder pressure of the Dimethyl ether compressor is too late to release and restart, when the motor is started under heavy load, it may constitute a stall failure.
Through the above introduction and analysis of the common faults of Dimethyl ether compressor, hope it helps you.
