Calculation of pumps

How is the installation height of a pump determined?
The issue of the installation height of a pump is related to the phenomenon of \"cavitation\"; therefore, an allowable cavitation head is specified, and this value can be found in the pump’s data sheet. Thus, the allowable installation height of the pump is given by H = Ps/ρg – Pv/ρg – ΣH – ΔH. Of course, the specific calculation process can be found in textbooks on chemical engineering principles, with the solution to such problems usually presented in the second chapter
The installation height of the pump is generally at ground level. There are many factors to consider: 1. Is the allowable net positive suction head sufficient? 2. Vibration problems of the pump 3. Pump maintenance issues 4. Inspection issues during pump operation generally involve first determining the installation height of the pump, which is set at ground level, and then determining the installation height of the container on the suction side of the pump. The container cannot be determined first, and then the pump. For underground containers or pools, there are different specifications regarding the pump height.
