The hydraulic system of medium and small hydraulic Excavator Spare Parts has a clear trend of changing to a variable system. Because the variable system compensates by increasing the flow rate when the pressure is reduced during the operation of the oil pump, the hydraulic pump power is kept constant, that is, the Excavator spare parts equipped with the variable pump can often fully utilize the maximum power of the oil pump. When the external resistance increases, the flow rate is reduced (the speed is reduced), and the digging force is multiplied; a three-circuit hydraulic system is used. Generate three independent work movements that do not affect each other. Achieve power matching with the slewing mechanism. The third pump is switched on in other working motions and becomes the second independent fast motion of the open circuit. In addition, hydraulic technology is commonly used on excavators, creating conditions for the application and promotion of excavators for electronic technology and automatic control technology.
