That is, pump head = suction head + pressurized water head. When choosing a water pump, be careful not to ignore it.　　 Pump head = net head + head loss Net head refers to the height difference between the suction point of the pump and the high control point, such as pumping water from a clean water tank and sending it to a high Solar Panels for Solar Pumps water tank. It should be pointed out that the head marked on the nameplate refers to the head that the pump itself can generate, and it does not include the loss head caused by the frictional resistance of the pipeline water flow.　

The head of a water pump refers to the height of the water pump that can lift water, usually expressed by H, and the unit is m.1MP, the inlet and outlet pipe diameters are the same and the pipeline resistance is negligible, the pump lift is equal to the lifting height. The net head refers to the height difference between the suction inlet of the clean water tank and the high water tank. Expressed by Q, the unit is m3/H, L/S. The lift of a centrifugal pump is different from the lifting height (lifting height).

Otherwise, there will be no water.2016-04-20 The flow rate of the 　　 water pump is also called the water delivery volume, which refers to the volume of water delivered by the pump per unit time. The head of the centrifugal pump is based on the center line of the impeller and consists of two parts.

The lifting height of the pump refers to the vertical height at which the pump sends liquid from a low place to a high place.. Only when the pump's inlet and outlet containers are at 0. The vertical height from the center line of the pump impeller to the water surface of the water source, that is, the height at which the pump can suck up the water, is called the suction lift, referred to as suction; The height of is called pressure head, or pressure range for short
