The choose and use of submersible pump

Submersible pump and exquisite light, play an insignificant role in rural production career, in the choose and buy and use should be careful how much point as a condition:

First, the choose and buy

Submersible pump of choose and buy should pay attention to its model, flow and level. If choose the specifications of the unhappy when, will be helpless to lose the rest of the water yield, diving exhibition of axial flow pump unit efficiency). In addition, still should determine the incense of the motor position, certain types of submersible pump forward and inversion are available out of the water, but the reverse when the water yield and large direct current, its reversal motor winding. For the prevention of submersible pump leakage caused shock incident, when working on the leakage switch cover.

Second, the device

To aerial device submersible pump, cable, power cord don’t be too long. Don’t make the cable forces during the unit water, lest cause submersible axial flow pump power cord rupture. Submersible pump don’t sink into the mud, will not cause bad heat dissipation and burn out motor winding.

Three, use

1. The measures to prevent air pressure when boot in the industry. Supply voltage differ with extra voltage not 10%, can lead to high voltage motor overheating and burning of windings, motor speed rising voltage is too low, such as amounted to less than 70% of the extra speed, start centrifugal switch will close, cause the startup winding short time back to heat and even burn winding and library container. Spinor pump do not frequently switch motor, this is so electric submersible axial flow pump stall recovery can be created, if the instant boot, can make the motor load startup, start from a direct current is too large and burn winding.

2. Do not let water pump overload operation for a long time, don’t smoke sediment concentration of water, electric pump to take off the shipping line time shoulds not be too long, lest make the motor overheating and burning. Units in operation, fuck I must inspect whether the submersible axial flow pump operation voltage and direct current (dc) at any time within the numerical procedures on nameplate, if is not consistent with what should make motor run, find causes and troubleshooting.

More than 3 hours to review motor, such as found by the crack under the corrupt, rubber sealing ring or effect, etc., should be timely replacement or repair, with waterproof into the tool.
