Water Ring Vacuum Pump Impeller Assembly

The vacuum pump is made up of: pump cover, pump body, disk, impeller, mechanical seal, motor and other parts. Properly assembling the impeller on the shaft can ensure that the water ring vacuum pump has good volume efficiency and prevent vibration.water-ring-vacuum-pump-impeller-assembly

Vacuum pump impeller center hole there is a screw hole on each side, to be a tool, a middle thick plate drilling, tapping, the size is smaller than the motor shaft, the hole at each end milling a slot, bolt fix the two screw holes on the impeller impeller, with a larger spin top tight motor shaft bolt and rotate this bolt with the motor shaft, impeller will slowly come out. If it’s too tight to get out, you can use a fire – baked impeller to inflate it out of the impeller.roots-vacuum-pump-is-used-in-vacuum-aluminum-plating.

When the impeller is mounted on the shaft, its end face must beat within the allowable range. Cover before and after impeller with axial clearance is small, big face runout will cause the impeller and the front and back cover of eccentric wear, not only to pump heat, increase power consumption, but also will increase the end clearance, increase the compression zone gas through the side clearance leakage, reduce the volumetric efficiency.rotary-vacuum-pump-in-medicine
