6、 ZXP stainless steel chemical self-priming pump corrosion-resistant self-priming centrifugal pump maintenance and disassembly:

The characteristic of this self-priming pump is its simple and reliable structure, as well as its durability. Under normal circumstances, it is generally not necessary to disassemble the pump frequently? Maintenance. Once a malfunction is detected, it can be resolved at any time.

When maintaining the pump, several main parts should be noted:

a. Rolling bearings: When the bearings wear out to a certain extent after long-term operation of the pump, they must be replaced.

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

c. Mechanical seal: Mechanical seals should generally not be disassembled without leaking liquid? check If there is a serious leakage at the leakage port at the lower end of the bearing body, the mechanical seal should be disassembled and inspected. When installing and dismantling mechanical seals, they must be handled with care, paying attention to the cleanliness of the mating surfaces, protecting the mirror surfaces of the stationary and moving rings, and strictly prohibiting knocking and collision. The main reason for leakage caused by mechanical sealing is due to the rubbing of the mirror surface. The repair method can be to grind the friction surface to restore the mirror finish. Another reason for leakage in mechanical seals is improper installation or deformation and aging of the 'O' - shaped rubber sealing ring (or buffer pad). Do we need to adjust or update at this time? Reinstall the 'O' - shaped sealing ring.

2. Pump disassembly sequence:

a. Remove the motor or disconnect the coupling.

b. Remove the bearing assembly, check the radial clearance between the impeller and the front ring, and check if 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 sealing ring.

d. Loosen the fastening pin of the mechanical seal, pull out the dynamic ring part of the mechanical seal, check the fit between the dynamic and static ring end faces, and check the sealing condition of the "O" ring (or buffer pad).

e. Unscrew the fastening nut of the coupling and pull out the coupling.

f. Remove the bearing end cover and disassemble the pump shaft and bearing.

g. Assemble in reverse order during installation.
