Problems related to the installation and calculation of water intake tanks
Thread Content
There is a water pump with a head H = 32 and an allowable cavitation head of 4.3 meters. The depth at the bottom of the tank is 4 meters; calculations show that the allowable installation height for the pump is 3.3 meters. Therefore, the pump must be installed 1 meter below the 0-level. Now, a water intake tank is to be added – how should its installation height be calculated? Has a water intake tank been installed? Can the pump be installed on the 0-level plane? How is the size of a water intake tank calculated?
The main issue should be that the capacity of the water intake tank must be greater than the capacity of the pipeline from the bottom of the pool to the water intake tank! Check the volume of the pipeline and the water storage tank by yourself. It can be installed above the 0-meter level; this is just my personal opinion for reference only.

According to the calculations in Miao Tianlin’s article on \"Key Design Principles for Negative Pressure Tank Water Intake Devices,\" the designed volume of the negative pressure tank should be 4 to 4.5 times that of the water intake pipe, with a height-to-diameter ratio of 1.2 to 1.5 for the tank.
I think it can be installed on the 0 plane.
Since the allowable installation height has been determined to be 3.3 m, it must be 1 m below 0, and this has nothing to do with the water intake tank. If it’s at 0, it will also vaporize in the water intake tank. The water intake tank solves the problem of air entrapment, but it cannot solve the problem of cavitation.
The designed volume of the negative pressure tank should be 4 to 4.5 times the volume of the water intake pipe, with a height-to-diameter ratio of 1.2 to 1.5 for the water intake tank.
