What caused the submersible electric pump speed is too low?

When we were in the use of submersible pumps, sometimes will find electric pump speed is too low, this led to our pumping efficiency is lower, so we will have to find out the cause of electric pump speed to reduce, so as to ensure the efficiency of the electric pump.

1, the voltage of electric pump down, cause there are many reasons for this, may be there are too many people in power, in the peak of power. Also grew up may have line current on its pressure drop is too large, lead to reduce the load on both ends of the voltage. This is one reason we don’t have any good solution.

2, change the motor does not form a complete set, will result in low speed.

3, the fault of electric pump itself, on the impeller and pump shaft used for fastening nut loose, or even damage of deformation. And the motor burned out or fail.

The above three reasons is the cause of submersible electric pump speed is too low, generally one of the most common is the first reason, but it is hard to solve, so we can solve the problem is that both 2 and 3.
