The various faults of the compressor often do not appear suddenly, but have certain omen, sometimes appearing in various visions, sometimes appearing as numerical values on the instrument.
Therefore, today we will discuss the various signs before the occurrence of various types of compressor failures, and provide reference for the majority of compressor users to predict equipment failures and maintenance in advance.
First, abnormal noise, abnormal vibration
An abnormal sound that occurs during operation is an "alarm" for equipment failure. The vibration is severe during operation.
The reasons for the abnormal noise of the compressor may be:
The bearing of the main engine is worn, the shaft is unbalanced, and the yin and yang rotor are damaged.
The main engine is under heavy load, and the pressure on the rolling or pipe network is unbalanced;
Bolts, nuts, washers and fixing brackets are loose;
Inside the equipment, debris and foreign matter fall into the device;
It is also possible because the compressor unit is running close to the overhaul period.
At this time, the axial and radial turbulence of the screw gradually tends to the maximum design allowable value, which causes a large change in the gap between the screw and the screw, between the screw and the main body casing and the front and rear end faces, thereby causing friction. , vibration and various sounds.
