Notes during the period when the pump is not working.
1) Drain the stagnant liquid inside the pump. In pump houses with no heating system, when the pump stops working in winter, you should pay attention to prevent it from frost cracking.
2) Wipe and clean the surface of pump head and pump motor. Smear anti-rust oil on surfaces that will not be used for a long time to prevent rusting.
3) If the pump, including standby pumps, is not used for a long time, you should start it less than every 30 days and let it run for 10 minutes to prevent internal rusting, which would otherwise make the pump fail to run.
deep submersible well pump maintenance and inspection
Generally, you should overhaul the pumping unit once every year to replace the worn-out parts and ineffective parts. You should disassemble the pumping unit in order in a correct way to prevent unnecessary damage caused by improper disassembly methods.
Deep submersible well pump disassembly
1) First, take down the elastic pin, replace ineffective elastic rubber sheath.
2) Pull out the locating pin, use crow bar to dismantle the pump lid. You must not directly pull up the pump lid only with the hoist.
3) Make full advantage of the jackscrew to disassemble the shaft bearing.
4) When dismantling the shaft bearing, you should screw the loop bolts into the holes on the bearing gland. Use lama or other special tools to disassemble the bearing and bearing gland together.
5) If you need to hoist up the whole rotor, do remember to loosen the gland of mechanical seal first to separate friction pairs of the dynamic ring and the static ring. Otherwise, you may damage the end faces of friction pairs.
