The flow of the special pump for the filter press is also called the water delivery volume, which refers to the amount of water delivered by the pump in a unit time. It is represented by the symbol Q, and its units are liters / second, cubic meters / second, and cubic meters / hour.
The lift of the special pump for the filter press feeding means the height that the pump can lift the water, usually expressed by the symbol H, and its unit is meter. The lift of the centrifugal pump is based on the centerline of the impeller and is divided into two parts. The vertical height from the centerline of the pump impeller to the surface of the water source, that is, the height that the pump can suck up the water, is called the suction lift, referred to as the suction stroke; the vertical height from the centerline of the pump impeller to the water surface of the water outlet, that is, the pump can press the water up The height is called the pressure head, which is called pressure head for short. That is, pump head = suction head + pressure head. It should be noted that the head shown on the nameplate refers to the head that can be generated by the pump itself. It does not include the lost head caused by frictional resistance of the pipeline flow. When choosing a water pump, pay attention not to be ignored. Otherwise, water will not be pumped.
