The doosan excavator hydraulic pump is the power component of the hydraulic system, its function is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of doosan excavator hydraulic pump generally include gear pumps, vane pumps and plungers.

The working principle of the doosan excavator hydraulic pump is that the movement brings about a change in the volume of the pump cavity, thereby compressing the fluid so that the fluid has pressure energy.
The necessary condition is that there is a change in the sealing volume of the pump cavity.
1. According to whether the flow can be adjusted, it can be divided into: variable pump and quantitative pump. The output flow can be adjusted according to needs, called variable pump, and the flow can not be adjusted, called quantitative pump.
2. According to the pump structure commonly used in hydraulic system, it is divided into three types: gear pump, vane pump and plunger pump.
The flow is well understood and can be understood as the size of the water flow. The flow rate is the volume of hydraulic oil discharged by the hydraulic pump per unit time. The flow rate is large and the action is naturally fast. Therefore, after replacing the pump with a slow speed, first check whether the flow rate of the pump meets the standard. Because the flow of the new pump will be set in the middle.
Each excavator hydraulic pump flow adjustment is different. Therefore, the hydraulic pump of the new hydraulic pump needs to adjust the hydraulic pump flow according to the actual situation of the site in order to obtain a satisfactory speed. In addition to the hydraulic pump that can adjust the maximum flow, the hydraulic pump flow also depends on the control oil pressure.
The hydraulic pump flow of the excavator is changing all the time. If the control handle has a large operation range, the hydraulic pump flow increases and the work efficiency is improved. When micro-operation is required, the operating range of the handle is small, and the flow rate of the hydraulic pump will be reduced at this time, so as to improve the operation accuracy and reduce the action speed.
