The hydraulic pump is the power component in the hydraulic system, which is driven by the engine or electric motor, sucks oil from the oil tank, forms pressure oil and discharges it to the actuator. The hydraulic system of the excavator is a combination that connects various hydraulic components together with pipelines according to the transmission requirements of the working device of the excavator and each mechanism. In terms of hydraulics, it is divided into main pump and pilot pump, of which the main pump (hydraulic pump) is usually called a large pump, which is to supply oil to the entire hydraulic system, in short, it is to generate pressure to provide action for the excavator. The pilot pump, generally a gear pump, is now connected to the main pump of the excavator to provide pilot oil for the operation of the excavator (that is, the oil required for the operation of the handle of our excavator). So what is the working principle of the hydraulic pump of the excavator? The following is continued by Elephant Fluid Power:
The hydraulic system of the excavator is composed of some basic circuits and auxiliary circuits, including working circuits, pressure limiting circuits, unloading circuits, buffer circuits, throttle speed regulation and throttle speed limiting circuits, walking speed limiting circuits and pilot valve control circuits. Its components are mainly composed of working pump, oil replenishment pump, pilot control valve, distribution valve, safety valve, boom cylinder, small arm cylinder, bucket cylinder, oil tank and related pipelines. During the working process of the hydraulic system of the excavator, the hydraulic oil is sucked by the working pump through the oil filter from the bottom of the oil tank, and the hydraulic oil with a certain pressure is output from the oil pump into a set of parallel distribution valves. Through the handle→ pilot valve → the working valve group to achieve the corresponding action, the system through the total safety valve on the main oil circuit to limit the total pressure of the entire system, each group of working oil circuit safety valves respectively to the corresponding oil circuit overload protection and oil replenishment effect.
