Vacuum pump repair _ vacuum pump fault classification

According to the process of the fault that occurs, the fault occurs slowly as a gradual fault, and the fault suddenly occurs as a sudden fault. From the perspective of the actual vacuum pump fault, it can be divided into the following categories:

First, according to the process of the fault that occurred, the fault slowly occurs as a gradual fault, and the fault suddenly occurs as a sudden fault.

Second, according to the order of failure, divided into primary faults and secondary faults

In the case of a primary failure, a small failure sometimes occurs in a certain part. This failure has not been discovered for a while or has no significant effect on the operation of the vacuum pump.

In the case of secondary failure, when the operation continues, the part of the primary failure causes the imbalance of the vacuum pump or the debris to enter the adjacent operating part, causing “healthy” partial damage, and the situation is further developed until the vacuum pump as a whole or the drug-carrying part Destruction 2 stops running, and the latter stage is a secondary failure. For example, a vacuum pump may initially have a slight friction on the blade, and then the blade will wear the unevenness of the cylinder and still operate, and the worn cylinder damage will expand to the card main vacuum pump to stop. Vacuum pump maintenance technicians face the serious damage of the inner wall of the cylinder. It is necessary to find out what is the primary fault in order to take preventive measures correctly. Generally, the primary fault process is long, and the secondary fault occurs in a short period of time. As the advanced nature of the vacuum pump fault diagnosis, it can be diagnosed when the primary fault just occurs, and timely maintenance measures are taken to make the loss less. . The post-horse gun type that is diagnosed after the occurrence of a secondary fault is not desirable, which not only causes a large loss, but also makes it difficult to analyze the fault after the fault, which is not conducive to future improvements.
