For centrifugal submersible pump or mixed flow submersible pump, the flow over the general assembly to increase the pump shaft power, but also make the submersible sewage pump overload situation. For axial flow submersible pump submersible pump, the flow is too small will make the submersible sewage pump shaft power will increase, resulting in submersible sewage pump overload. In the face of such a situation, we should take the following approach.
Appropriate adjustment of the valve, of centrifugal submersible pump or mixed flow submersible pump should reduce the flow, of axial flow submersible pump should increase the flow, flow submersible pump appeared in the normal range, to avoid axial flow submersible pump should be increased in the use of overload appears in the process of the phenomenon.
Attention to the size of the flow of diving sewage pump performance, and through the simple method to improve, not only can a submersible axial flow pump efficiency maximization of the role, but also to a certain role in the maintenance. We may wish to do a good job to deepen the understanding of submersible sewage pump.
