Air compressor referred to as air compressor, as a common machinery and equipment, in the field of industrial and agricultural production has been widely used. The problem is that the motor as an air compressor power equipment, the failure rate is generally higher than the other equipment of the motor. The reason why this paper will be about the causes of air compressor motor damage and how to protect the basic concepts and arguments, hoping to play a role in attracting brick, causing air compressor manufacturing industry and the majority of users concerned about the common participation in the discussion.

Cause Analysis of Damage of Air Compressor

Air compressor motor damage is a multifaceted and comprehensive. We went to the air compressor work, the production site on-site investigation that the cause of damage to the air compressor motor in addition to other motor power equipment with common common fault factors, but also with the air compressor itself, the specific operation of the fault factors The Analysis summarized the following points:

Requirements for working conditions of air compressor

Air compressor mechanical operation, electrical control is relatively simple, are generally single unit independent work, in a professional operation of the occasion, the occurrence of failure is not timely, relatively speaking, the duplication of the increase in duplication.

The reliability and sensitivity of automatic pressure switch

The start and stop of the air compressor is usually driven by the automatic pressure switch directly to the AC contactor to achieve automatic control of the motor. The automatic use of automatic pressure switch most of the mechanical structure, the use of spring compression and release energy action contacts. Perhaps the inherent pressure of the automatic switch or due to improper regulation, such as the impact of different reasons. In the control of air pressure process, there may often be two kinds of abnormal action phenomenon:

1, the pressure automatically switch off the pressure when the anti-action, so that the motor can not run properly, the pressure continues to rise, resulting in overload overload motor operation, serious failure may occur when the phenomenon.

2, automatic pressure switch transient shock phenomenon, while the AC contactor to produce synchronous shock. Resulting in the main contact of the AC contactor in the frequent start of the current impact of burning or sticky death caused by downtime or phase failure operation.

Automatic exhaust valve failure

Air compressor is generally no automatic exhaust device, when the pressure reaches the set pressure, the automatic discharge after the shutdown pressure, preset the next no-load start, exhaust valve failure, the air compressor cylinder pressure can not be released, equal to The motor is loaded and may cause difficulty in starting or stalling.

Running in the sudden stop power

Automatic control of the air compressor, encountered a sudden intermittent transmission situation, because the air compressor cylinder pressure is too late to release and restart. The motor is in heavy start, it is likely to form a stall failure.
