Deep well submersible pump proper use and maintenance methods

To ensure the normal operation of your use of deep well submersible pump, weihu special remind you must be carried out in accordance with the following requirements.

Deep well submersible pump before use, must be used, check the motor insulation resistance by megger are the lowest value shall not be less than 50 m Ω.

Water motor should be open to infuse water plug, filled with clean water and then tighten the screw not to infuse water plug directly into the well after off.

Check cable broken, broken before use. If there are any damage should be timely exchange, in case of leakage.

Deep well submersible pumps before launching to infuse water pump and then idling 1-2 minutes, and starting twice, check whether the starting and idling is normal, whether to conform to requirements. If turned to the contrary, arbitrary two-phase wiring switch.

Check for cracks, Yang pipe connection is firm.

Deep well submersible pump Wells and lifting, must not be allowed to pull the cable, in order to avoid cable damage or disconnect joint, the accident caused by. Should use wire or card board well and lifting.

Supply voltage should be controlled within the scope of the rated voltage of plus or minus 5%, this machine can work normally. If the voltage is too low or too high, the motor should not continue to use, to avoid long-term work under the over voltage or under voltage motor damage.

Wells with submersible pumps should be lifted vertically into the water, not sideways. The water depth with under the dynamic water level 5 meters advisable.

Wells with submersible pumps shall not deliver high sand content water or mud.

Well with actual submersible pump head should be used within 0.8-1.1 times rated head, to improve the efficiency of the unit, saving energy, at the same time avoid motor overload.

Electrical wiring must be real, to avoid motor open phase running burned.

Cable must be frequently inspect for cracking, scratches, etc., have timely replacement or repair.

Oil-immersed motor if there is a leak phenomenon, should be timely to the manufacturer or pits repair, replacement of sealing components.

Water motor should always clean up cavity of the sand, the replacement of motor cavity clean water.

Wells with submersible pumps running after six months, should check maintenance, replacement of damaged parts.

Wells with submersible electric pump after use, water motor should put clean water, clean electric pump clean, besmear antirust oil, and the vertical in a dry place.
