China manufacturer offer main sealing oil pump KG70KZ/7.5F4

 

DESCRIPTION

 

The main sealing oil pump KG70KZ/7.5F4 is formed by the meshing of the spiral grooves on the main screw and the driven screw, as well as their coordination with the inner surface of the three holes of the bushing, to form several stages of dynamic sealing chambers between the inlet and outlet of the pump. These dynamic sealing chambers continuously move the liquid from the inlet of the pump axially to the outlet of the pump, and gradually increase the pressure of the transported liquid. Thus forming a continuous, stable, and axially moving pressure liquid. When the active screw rotates, it drives the driven screw that engages with it to rotate together, and the meshing space volume of the screw at one end of the suction chamber gradually increases, while the pressure decreases.

 

Overhaul OF main sealing oil pump KG70KZ/7.5F4

 

1. Recheck the oil pump center and make records (mark the wheels)

2. Motor disconnection: Remove the local power cord of the oil pump motor.

3. Remove the oil pump motor: Use a pry bar to directly remove the oil pump motor.

4. Disassemble the oil pump: Loosen the fastening bolts of the pump wheel housing and remove the wheel housing; Loosen the coupling bolts; Remove the motor; Loosen the flange bolts at the inlet and outlet of the oil pump; Clean up the maintenance site.

5. Disassembly of oil pump: Pull down the oil pump coupling and remove the key; Measure and record the compression amount of the mechanical seal; Loosen the fastening bolts of the dynamic ring, remove the fastening bolts of the static ring, and remove the mechanical seal; Measure and record the spindle shaft displacement.
