The stainless steel sewage pump is the latest product of the renewal and replacement of the pump in our country. The following design techniques are introduced.

1, when the pump runs at the design point, generally speaking, the power of the pump is less than the rated power of the motor. The use of this pump is safe, but when the pump head is lowered, the flow will increase. From the pump performance curve, we can see that the power will also increase.

2. When the motor is overloaded, it can either protect the action of the system to stop the pump turn, or protect the failure of the system to cause the motor to burn down. The pump head is lower than the design operation point head use, in practice is also often encountered.

3, non clogging sewage pump head selected too high, but the actual use is to lower the lift pump use, another situation is in use the pump operating point is not well established, in other words the flow of pump need to be adjusted, there is a need to change the location of pump use.

4, as long as we choose the motor rated power is slightly more than the power of hump point value, then in 0 traffic to the entire range of maximum flow, whether you run on that one point, no power clogging sewage pump will not exceed the power of motor and pump overload, to have the performance of the pump, no matter the selection is still in use, will be very convenient and reliable.
