water ring vacuum pump of phenomenon to be avoided in maintenance

In the process of using water ring vacuum pump, due to the influence of various factors, some failures often occur. In order to ensure the normal operation of the water ring vacuum pump, the relevant components need to be repaired.

1. Failure can not be judged and analyzed correctly, and it is common to dismantle and unload blindly

Some vacuum pump maintenance personnel were not clear about the structure and principle of the water ring vacuum pump, did not carefully analyze the cause of the failure, and could not accurately determine the failure location. They blindly disassembled and unloaded the machinery with the idea of “approximate, similar”. As a result, not only the original failure was not eliminated, but also new problems emerged due to poor maintenance skills and processes. Therefore, when the machinery fails, it should be detected by the detection equipment. If there is no detection equipment, it can be determined by traditional fault judgment methods and means such as “asking, looking, checking, and testing”, combined with the structure and working principle of water ring vacuum pump.

2. The phenomenon of “replacement and repair” exists to varying degrees

It is relatively difficult to judge and eliminate the fault of water ring vacuum pump. Some maintenance personnel have always used the method of replacement test. No matter large or small parts, as long as the parts that may cause the fault are replaced one by one, the fault is not eliminated, and the parts that should not be replaced are replaced at will, increasing the user’s expenses.

Some faulty parts can be completely restored to their technical performance through repair, and can be repaired without complex repair processes. However, maintenance personnel require users to replace new parts, and blindly adopt the method of “replacement and repair”, resulting in serious waste.

Water ring vacuum pump: the above blind replacement test and the practice of blindly replacing repairable parts still exist in some repair units to varying degrees. During maintenance, carefully analyze and judge the cause and position of the fault according to the fault phenomenon, repair the parts that can be repaired to restore the performance, and eliminate the blind replacement of parts.

Water ring vacuum pump: In addition, many of the replaced spare parts can be used after being completely repaired by new processes such as brush plating and spraying. In actual work, maintenance workers are generally unwilling to repair. There are many reasons why maintenance personnel are unwilling to repair damaged equipment. First, there is a lack of necessary maintenance tools. Proper special removal tools and measuring instruments shall be provided; Electricians need to be equipped with accurate digital multimeter, regulated power supply, tester and other tools.

Second, there is a lack of corresponding incentive mechanism. The maintenance workers worked hard to repair a spare part with a high price, but did not get any encouragement or reward. Over time, the maintenance workers gradually lost their enthusiasm to repair and reuse the waste parts. Therefore, incentive measures should be taken to reward the personnel who repair the spare parts based on the price, reuse value, reliability, etc. of the spare parts, and the percentage of the original spare parts price, and related to the monthly and annual performance, so as to encourage the enthusiasm of the maintenance personnel to repair and reuse the waste parts.
