What is the head of the pump? What is the head of the unit of measurement? Xiaobian to illustrate how to calculate the pump head, to answer your doubts! Pump head calculation Pump head is the pump The total head produced, the pump head = pump outlet gauge pressure - pump inlet gauge pressure. For example, a multistage centrifugal pump at a certain speed, the test medium is water at room temperature (density by 1000 kg / m3), the measurement of the commonly used units of meters (m), the mathematical expression The flow rate was 75.1 m3 / h, the discharge pressure of the pump was 1.62 MPa (the true diameter of the pressure measuring section was 100 mm), the suction pressure was 0.035 MP (the diameter of the pressure measuring section was 150 mm), the horizontal position of the pressure gauge center was the same . The working procedure of the lift calculation steps are as follows: It can be seen in the test parameters to be measured are the pump inlet and outlet suction pressure and discharge pressure, import and export level relative to the reference plane vertical win height, the pump import and export measurement Pressure section diameter (used to calculate the flow rate) and other parameters. It should be noted that although the head calculation formula is the same, but due to the use of different instruments of its calculation method is different, the specific requirements can refer to the standard test methods.
