    摘要: A pumping system includes a water pump for moving water. The pumping system includes means for determining a value indicative of a blockage that inhibits the movement of water through the pumping system, and means for determining a performance value of the pumping system. In one example, the pumping system includes means for comparing the performance value to the value indicative of a blockage and means for controlling the pump in response to the comparison. In another example, the system includes means for determining a change in power consumption of the water pump. In another example, the system includes means for determining a threshold value and means for controlling the pump when the performance value exceeds the threshold value. In another example, the system includes means for determining a difference value based upon a plurality of performance valves during a first time period and a second time period. A method of controlling the pumping system is also included.
