Maintenance Measures Of Multistage Centrifugal Pump For Mine

1. It is best to continuously turn on the machine for 8 to 16 hours every day. Spare parts for 24 hours continuous work should be replaced and repaired regularly. The replacement period is generally two to three months. Does not affect production, non-continuous work production can be repaired at any time.

Second, when the ratio of the transport medium is greater than 1.2, an additional motor should be equipped, otherwise it will affect the head or cause the motor to burn out.

Third, after a period of use, it is found that the mechanical seal end face leakage is caused by carbonyl surface wear, should adjust the moving ring, relax the two screws of the stainless steel semicircle, suitable for forward, rotate the pump shaft by hand with easy no resistance, leakage will occur for loose, too tight easy wear affect the life of the mechanical seal.

Fourth, maintenance: remove the pump shell, front and rear pump cover, impeller, mechanical seal components in the dirt, and wash clean, no damage can continue to use, to see whether the mechanical seal is damaged, moving ring end wear or scratch less available fine metallographic sand on the plate for grinding, can continue to use.

Five, the unpacking sequence is: remove the motor, support, bottom plate screws, remove the mechanical seal cover, allow the water nozzle, loosen the start ring clamp ring bolts, static ring pressure plate bolts, front and rear pump cover bolts, the blade shaft tie rod Feng ding screw, screw out 3~5mm, beat the tie rod with a hammer, the impeller is loose, remove the tie rod, impeller and mechanical seal, when unloading mechanical seals should be manually operated Do not knock with metal tools to prevent damage.
