Maintenance and Disassembly

The characteristics of the pump are simple and reliable structure, durable. Under normal conditions, the pump generally does not need to be disassembled and maintained frequently. When a fault is found, it can be eliminated at any time.

1. Pay attention to several main parts when maintaining the pump.

A. Rolling bearings: After the pump has been running for a long time, the bearings must be replaced when they are worn to a certain extent.

B. Front sealing ring and rear sealing ring: When the sealing ring is worn to a certain extent, it must be replaced.

C. Mechanical seal: Generally, the mechanical seal should not be disassembled for inspection if there is no leakage. If serious leakage occurs at the leakage port at the lower end of the bearing body, the mechanical seal should be dismantled and inspected. When assembling and disassembling the mechanical seal, it must be handled with care, pay attention to the cleaning of the mating surface, protect the mirror surface of the static ring and the moving ring, and it is strictly forbidden to knock and collide. The main reason for the leakage due to the mechanical seal is that the mirror surface of the friction pair is brushed. The repair method is to grind the end face of the friction pair to restore the mirror surface. Another reason for the leakage of mechanical seals is that the "o"-shaped rubber sealing ring (or cushion) is improperly installed, or deformed and aged. At this time, it is necessary to adjust or replace the "o" ring seal for reassembly.

2. Disassembly sequence of oil pump:

A. Remove the motor or disengage the coupling.

B. Remove the bearing body assembly, check the radial clearance between the impeller and the front port ring, and check whether the impeller nut is loose.

C. Remove the impeller nut, pull out the impeller, and check the radial clearance between the impeller and the rear seal ring.

D. Loosen the set screw of the mechanical seal, pull out the moving ring part of the mechanical seal, check the fit of the end faces of the dynamic and static rings, and check the sealing condition of the "o"-shaped sealing ring (or cushion).

E. Unscrew the set nut of the coupling and pull out the coupling.

F. Remove the bearing cover and remove the pump shaft and bearing.

G. Assembly can be done in reverse order during installation.
