Maintenance and disassembly of environmentally friendly self-priming pump
The pump is characterized by its simple, reliable structure and durability. Under normal circumstances, the pump generally does not need to be disassembled and maintained frequently. When a fault is discovered, it can be rectified at any time.
. Several main parts should be paid attention to when maintaining the pump
. Rolling bearings: When the bearings are worn to a certain extent after long-term operation, they must be replaced.
B. Front sealing ring, rear sealing ring: When the sealing ring is worn to a certain extent, it must be replaced.
Mechanical seal: The mechanical seal should generally not be disassembled for inspection if it does not leak. If serious leakage occurs at the leakage port at the lower end of the bearing body, the mechanical seal should be disassembled and inspected. When assembling and disassembling the mechanical seal, you must handle it with care, pay attention to the cleaning of the mating surface, protect the mirror surfaces of the static ring and the moving ring, and knocking and collision are strictly prohibited. The main cause of leakage due to mechanical seals is the roughening of the friction mirror surface. The repair method: the friction pair end surface can be ground to restore the mirror surface. Another reason for mechanical seal product leakage is improper installation of the ring or deformation and aging. At this time, the ring needs to be replaced and reassembled.
, Pump disassembly and assembly sequence
, Remove the motor or take out the coupling.
B. Remove the bearing body assembly, check the radial clearance between the impeller and the front ring, and check whether the impeller nut is loose.
. Remove the impeller nut, pull out the impeller, and check the radial clearance between the impeller and the rear sealing 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 moving and stationary rings, and check the sealing condition of the circular seal ring.
, unscrew the set screw of the coupling, and pull out the coupling.
, Remove the bearing end cover, and remove the pump shaft and bearings.
When installing, just assemble in the reverse order.
