Application And Application Of Submersible Pump

Oct 09, 2017

Submersible pump exquisite light, in the rural production career plays an insignificant role in the purchase and use should pay attention to how many points:

One, buy

Purchase submersible pumps should pay attention to its model, flow and elevation. Such as the use of unscrupulous specifications, will be able to lose the remaining water, so that the efficiency of the unit can not be cast. In addition, you should also find out the location of the motor, some types of submersible pump forward and reverse can be when the water, but reverse the water when the small, DC large, the reverse will destroy the motor windings. In order to prevent the submersible pump in the body when the operation leakage caused by electric shock, should be installed leaking shields.

Second, the device

When the submersible pump is installed, the cable should be overhead and the power cord should not be too long. Do not make the cable force when the unit is in water, so as not to cause the power cord to break. Submersible pumps do not sink into the mud, or lead to poor heat dissipation and burn the motor windings.

Third, the use of

1. Heavy volume to prevent the start in the industrial pressure. The power supply voltage and the external voltage is not a difference of 10%, the voltage will cause the motor overheat and burn the winding, the voltage is too low, the motor speed rise, such as less than 70% of the extra speed, Winding short time to pay back the heat and burn the winding and the container. Spin the pump do not frequent the door motor, which is so the pump will stop when the warmer, if the boot, the motor load will start, lead to start the DC is too large and burn the winding.

2. Do not let the pump run over long-term load, do not smoke a large amount of water, the pump off the sea should not run too long, so that the motor overheating and burned. The crew in the operation, the operator must always check their operating voltage and DC is on the nameplate on the code within the value, if not match the motor should stay running to find the cause and troubleshooting.

3. Time to review the motor, such as found under the cover with cracks, rubber seal ring corrupt or effective, etc., should be replaced or repair in time to water penetration tools.
