Disassembly and Assembly of QJ Deep Well Pump

Demolition of Deep Well Pump

With the removable wrench, remove the water section, with the dismantling tube in the lower part of the pump impact hammer sets, impeller loose, remove the impeller, hammer-shaped sets, remove the guide shell, so unloading the impeller, Upper guide shell, check valve and so on.

Removal of motor

Remove the base, thrust bearing, thrust plate, lower guide bearing, connecting seat, throwing sand, remove the rotor, remove the upper bearing seat, stator and so on.

Assembly of deep well water pump

Before assembly check the cleaning of the parts of the rust, sludge, with the surface to be coated with butter rust, water pump large thread connection to oil.

(1) Assembly order of the motor: Stator assembly → Lower bearing housing assembly → Rotor assembly → Thrust plate → Shaft nut → Thrust bearing assembly → Base assembly → Upper bearing housing assembly → Skeleton oil seal → Connecting seat. Adjust the studs so that the motor shafts meet the specified requirements. And then on a good pressure regulating film, pressure spring and cover.

(2) the installation of the pump: the shaft and the water section fixed in the mounting seat, with the dismantling cylinder will impeller, hammer-shaped sleeve fixed on the shaft, and then install the guide shell, the impeller ... ... in turn loaded the upper shell , Check valves and so on.

Class 8 below the motor pump part of the assembly, the first in the water and the upper bearing bearing contact plane evenly distributed, add the same 3 ~ 3.5 mm gasket 3 to 4, and then even on the good pull nut, Shaft, pump shaft, good fixed bolts and lock ring, with the cartridge will be impeller, hammer-shaped sleeve fixed to the pump shaft, and then installed on the guide shell, the impeller ... ... so in order to pack the upper guide shell and so on. After the pump is installed, release the ribs, remove the gasket, and then tighten the ribs, and then turn the pump from the coupling, the rotation must be uniform.

Deep well pump to save

When the pump is not used for a long time, it should promptly send out the water inside the motor, wipe the surface clean, coated with anti-rust oil, on the relatively clean, dry, no chemical corrosion place. After the motor cavity is filled with water, strictly placed in the temperature of 0 ℃ and below the environmental conditions, or must be put in the cavity of water, to prevent cracking motor.
