Description

Many sites have a misconception that the lower the pumping head, the smaller the motor load. Therefore, when selecting a pump, the lift of the slurry pump is often selected to be very high. But in fact, for slurry pumps, when the water pump model is determined, its power consumption is proportional to the actual flow rate of the water pump. When we select a pump, its power and speed will also be determined, so the flow rate of the slurry pump will decrease as the lift increases. Therefore, the higher the lift, the smaller the flow rate and the smaller the power consumption. On the contrary, the lower the head, the greater the flow, and the greater the power consumed. Therefore, in order to prevent motor overload, it is generally required that the actual pumping head of the water pump should not be less than 60% of the calibrated head. Therefore, when a high lift is used with a low lift, the motor is easily overloaded and overheated, and in severe cases, the motor may be burned. If it is used in an emergency, a gate valve for adjusting the water output must be installed on the water outlet pipe to reduce the flow and prevent the motor from overloading. Pay attention to the temperature rise of the motor. If the motor is found to be overheated, the water outlet flow should be reduced or the machine should be shut down in time. It is also easy to cause misunderstandings. Some on-site workers believe that blocking the water outlet and forcibly reducing the flow will increase the motor load. In fact, on the contrary, regular high-power centrifugal pump drainage and irrigation units are equipped with gate valves on their outlet pipes. In order to reduce the motor load when the unit is started, the gate valve should be closed first, and then gradually opened after the motor starts. This is why.
