Maintenance of Automatic Self-Priming Peripheral Pumps

Automatic Self-Priming Peripheral Pumps are characterized by simple and reliable structure and durability. Normally, the pump does not need to be disassembled and maintained frequently. When the fault is found, it can be eliminated at any time.

There are several main parts that should be paid attention to when maintaining Automatic Self-Priming Peripheral Pumps:

A. Rolling bearings: When the bearings are worn to a certain extent after long-term operation, they must be replaced.
B. Front sealing ring and rear sealing ring: When the sealing ring is worn to a certain degree, it must be replaced.

C. Mechanical seal: Generally, the mechanical seal should not be disassembled for inspection when there is no leakage. If serious leakage occurs at the lower end of the bearing body, the mechanical seal should be disassembled and inspected. When assembling and disassembling the mechanical seal, it must be handled with care, pay attention to the cleanliness of the mating surface, and protect the mirror surface of the static ring and the moving ring. Knocking and collision are strictly prohibited. The main reason for the leakage caused by the mechanical seal is the roughening of the mirror surface of the friction pair. The repair method: the end face of the friction pair can be ground to restore the mirror surface. Another reason for leakage of mechanical seal products is improper installation of O-rings, or due to aging. At this time, the O-ring needs to be replaced for reassembly.
