What are the classification of hydraulic pumps? There are many types of hydraulic pumps. Dongsheng seal tells you that it can be divided into low-pressure pumps, medium-pressure pumps and high-pressure pumps according to the pressure. It can also be divided into fixed pump and variable pump according to whether the flow rate can be adjusted. According to the design structure of the pump, it can be divided into gear pump, vane pump and plunger pump. the gear pump and vane pump are mostly used in medium and low pressure systems, and the plunger pump is mostly used in high pressure systems.
First, what is work pressure? (Seal)
The output pressure when the hydraulic pump actually works is called the working pressure.
Two, what is the rated high pressure? (Seal)
Under normal working conditions, the higher pressure of continuous operation according to the test standard is called the rated pressure of the hydraulic pump.
Third, what is higher pressure allowed? (Seal)
It is under the condition of exceeding the rated pressure, according to the test standard, the higher pressure value that allows the hydraulic pump to run briefly, called the higher allowable pressure of the hydraulic pump.
