Common performance parameters for pressure in hydraulic pumping stations are as follows:

First, the rated pressure, under normal working conditions, the hydraulic pump continues to operate normally, to ensure the highest pressure allowed in normal working conditions. The rated pressure is based on the structure, material and various comprehensive factors of the equipment. In the hydraulic pump station, it must be less than this pressure during the working process.

Second, the maximum allowable pressure, which is well understood, is the highest value of the maximum output pressure of the hydraulic pump.

Third, the working pressure is the pressure that the hydraulic pump station outputs during actual work, also called the outlet pressure of the hydraulic pump. This pressure is determined by the load of the hydraulic pump station. It rises and falls with the size of the load.

Fourth, the suction pressure is opposite to the output pressure. The pressure at the inlet of the hydraulic pump becomes the suction pressure. The pressure of the self-priming pump is lower than the atmospheric pressure. The suction pressure should not be too low. If it is too low, it will cause insufficient oil absorption and cavitation.

The above are the common parameters of the pressure in the hydraulic pump station.
