ZX self-priming pump maintenance specifications

ZX self-priming pump, also known as horizontal self-priming centrifugal pump, is widely used in petroleum, chemical, metallurgy, machinery, chemical fiber and foodstuff industries. Its structure is simple, small size, light weight, high efficiency, Has been favored, especially in drainage, fire fighting as an emergency pump to use more prominent. Therefore, proper maintenance is particularly important. So ZX self-priming pump maintenance What are the rules? Today, Xiaobian here to introduce you to the following ZX self-priming pump maintenance specifications. ZX self-priming pump maintenance specifications First, maintain the pump should pay attention to several major parts: 1, rolling bearings: When the long-term operation, the bearing wear to a certain extent, the need to be replaced. 2, the front seal ring, the rear seal ring: When the seal ring wear to a certain extent, to be replaced. 3, mechanical seal: mechanical seal in the case of no leakage, the general should not open the inspection. If there is any serious leakage at the lower end of the bearing body, the mechanical seal should be disassembled. Assembly and disassembly of mechanical seals, you must gently, pay attention to the cleaning with the surface to protect the static ring and moving the mirror ring is strictly prohibited percussion collision. Leakage due to mechanical seal is mainly due to the friction mirror mirror hair to. The repair method: the friction end face can be polished to restore the mirror. Another reason for the leakage of a mechanical seal product is the improper installation of the O-ring or the aging of the seal. In this case, the O-ring needs to be replaced for reassembly. Second, the pump disassembly order: 1, remove the motor or prolapse coupling. 2, remove the bearing body assembly, check the radial clearance of the impeller and the front ring, check the impeller nut loose. 3, Remove the impeller nut, pull the impeller, check the radial clearance of the impeller and the rear seal ring. 4, loose the mechanical seal set screws, pull out the moving part of the mechanical seal, check the dynamic and static ring end of the fit, check the O-ring seal. 5. Unscrew the set screw of the coupling and pull out the coupling. 6, remove the bearing cover, remove the pump shaft and bearings. 7, the installation can be assembled in the reverse order.
