What kinds of hydraulic pumps are common in life?
1. According to the flow regulation, it can be divided into variable displacement pump and fixed displacement pump. The output flow can also be adjusted as a variable displacement pump as required, and the flow can not be adjusted as a fixed displacement pump.
2. According to the pump structure commonly used in hydraulic system, it can be divided into gear pump, vane pump and plunger pump.
Hydraulic expertise:
Gear pump: small, relatively simple structure, lax oil cleaning standard, more affordable, but the pump shaft is subject to unbalanced force, more serious wear, excessive leakage, typical of big brands are Rexroth gear pump, Bueyue gear pump, etc.
Hydraulic expertise:
Vane pump: divided into dual function hydraulic pump, such as screw pump. But it is not as extensive as the above three types.
