How to solve some faults of Submersible slurry pump2013-09-09
Below are four faults that Submersible slurry pump may occur and solutions.
1 Submersible slurry pump don’t absorb water.
The reasons of submersible slurry pump don’t absorb water have many possibility, the most main reasons are due to suction pipe block and impeller damage. To solve this problem, the main method is clean suction pipe blockage and repair or replace impeller.
2 Submersible slurry pump power is too large.
The reasons of too large submersible slurry pump power mainly include excessive packing compaction, friction in pump, bearing damage and pump roll quantity is too large. Solutions of the four faults are unscrew packing gland bolt, adjust the gap in pump, repair or replace damaged bearing, regulating the operation of pump.
3 Submersible slurry pump bearing fever
The reasons of submersible slurry pump bearing fever generally due to lubricating oil and bearing, include not clean lubricating oil, lubricating oil in bearing is too much or too little, bearing damage, etc. The main solutions are use clean lubricating oil, according to the requirements add lubricating oil for bearing, repair or replace new bearing.
4 Submersible slurry pump bearing life is short.
Submersible slurry pump bearing short life is due to friction in pump, impeller unbalanced, foreign body in bearing, unreasonably equip bearing, centre shaft is tortuous. Solutions are adjust impeller balance or replace new impeller, clear bearing foreign body, equip bearing again, change centre shaft.
