Description Of Excavator Hydraulic Pump
The current excavators are mostly swashplate variable dual hydraulic pumps. The so-called variable pump is that the displacement of the pump can be changed. It changes the stroke of the plunger by changing the swing angle of the swashplate to achieve the change of the volume of oil discharged from the pump. The advantage of the variable displacement pump is that it is within the range of adjustment, and can fully utilize the power of the engine to achieve the effect of high efficiency and energy saving. However, its structure and manufacturing are complex, and its cost is high, so it is responsible for installation and commissioning. According to the variable mode, it can be divided into manual variable, electronic oil flow variable, negative pressure oil flow variable, pressure compensation variable, constant pressure variable, hydraulic variable, etc. Nowadays, most excavators adopt Kawasaki cross constant power regulation system, which is mainly used for reverse flow control, power control and working mode control (controlled by electromagnetic proportional reducing valve)
