Submersible slurry pump purchase is the need to pay attention

Submersible slurry pump should pay attention to choose their models, flow and head. Such as the inappropriate use of specifications, will not be able to obtain sufficient water, can not play the unit’s efficiency. The micro submersible slurry pump is compact and lightweight, plays an important role in the rural production and living, in use should pay attention to the following points.

A submersible slurry pump should pay attention to choose their models, flow and head. Such as the inappropriate use of specifications, will not be able to obtain sufficient water, can not play the unit’s efficiency. In addition, should also figure out the direction of motor rotation, certain types of submersible slurry pump are transferred and can be reversed when the water, but the reverse when the water is small, current, its reversal will damage the motor windings. Submersible slurry pump in order to prevent the work under water leakage accidents caused by electric shock, leakage protection switch should be installed.

Two. Install a small submersible slurry pump, to the overhead cable, power line should not be too long. Do not water when the unit so that the cable force, so as to avoid power line fault. Submersible slurry pumps do not sink into the mud, otherwise it will lead to poor heat burnt motor windings.

Three. Try to avoid when in the low-voltage boot. The power supply voltage and rated voltage is not a difference of 10%, the voltage is too high will cause motor overheating and burn winding, the voltage drop in motor speed is too low, such as less than 70% of the rated speed, the centrifugal start switch closed, resulting in start winding electricity and heat and even burn winding and capacitor. Do not frequently switch motor, this is because the slurry pump will stop to have a return, if an immediate start, will start the motor load, resulting in excessive starting current and burn winding.

Four. Do not let the slurry pump long-term overload, do not draw large sediment water, dewatering slurry pump run time should not be too long, to avoid overheating and burning motor. Units in operation, the numerical operator must always observe the operating voltage and current is specified on the nameplate, the non-compliance should be the motor to stop running, find out the reasons and troubleshooting.

Five. Usually check the motor, such as a crack was found under the lid, rubber seal ring damage or failure, should be replaced or repaired, the water into the machine.
