Summary of rexroth oil pump
Rexroth oil pump is the power of the hydraulic system, it transmits (motor, internal combustion engine, etc.) the mechanical energy is transformed into the liquid pressure can.
Rexroth oil pump can be divided into positive displacement and the volume chamber (worm) two kinds.Is not volume type centrifugal pump, axial flow pump, etc., using high-speed rotating impeller makes imported produce vacuum suction liquid, and the export continuous output liquid pressure.Import and export are interlinked, the pump efficiency decreased with increasing liquid viscosity, and output the liquid quantity significantly reduced with outlet pressure.
A positive displacement pump through a closed space volume change to realize the oil absorption and oil pressure.When the closed volume change from small to big oil absorption, oil pressure by changed hours.Typical for lux LeZhu pump, plunger oil absorption, when be being pulled from the cylinder pressure in the oil.This kind of pump imports and exports were separated, separated efficiency depends on the suction pressure oil cavity structure technology gap between various parts of sport, oil viscosity, etc.The higher the viscosity, the high efficiency, capacity of almost remain the same (slightly affected by efficiency, additional pressure to 18 mpa, the oil will be compressed 1%).
