Deep well submersible pump in operation to pay attention to the six major issues

Deep well submersible pumps on the operation of the six major issues, some friends may also not very clear, let's learn about it.
1) deep well submersible pumps work, pay attention to the situation of water level decline, wells with submersible pumps shall not work out of the water surface.
2) The use of wells with a submersible pump stop, less water, noise and thermal protector frequent take-off and so on, should stop the pump in time.
3) Check the power supply voltage is too low or power, cable breakage or lack of phase.
4) Check whether the impeller jam or wear, whether the water chamber blockage, head too high or too low, the filter is blocked and so on. If a fault, find the appropriate solution.
5) In case of stator winding burnout and other failures, shall be sent to the repair unit repair. Reassembly, the sealing parts to be 0.2MPa pressure check.
6) When the submersible pump is used, it is found that the damaged cable is replaced immediately before it can be used. If there is a period of time, wells with submersible pumps should not be infiltrated into the water, should be cleaned. Such as wells with a submersible pump for pumping more viscous slurry, should be placed in clean water running for a few minutes, wash the pump slurry, and then dry painted anti-rust oil, stored in dry gout.
