A It has a closed volume and the closed volume changes alternately. The oil suction chamber and the pressure oil chamber cannot communicate with each other at any time.

A Common sealing rings include O-type, Y-type, V-type and combined slip ring type.

A Once the oil temperature in Hydraulic Systems exceeds 60°C, the viscosity of the oil will decrease, leakage will intensify, and a large amount of foam and gas will be generated, causing system pressure fluctuations, thereby affecting the overall operating effect.

A Fixed displacement pumps and variable displacement pumps. Gear Pump Vane Pump Piston Pump

A Check if Electric Motors is reverse rotated? Is the relief valve open? Is the preset pressure of the relief valve too low?

A High power density, good stability, high control accuracy, strong load adaptability, high reliability and good repeatability.
