In the broad field of construction machinery，Loader as an indispensable force，Its bucket turns over、Boom raising and lowering、Vehicle steering and other key actions depend on the efficient hydraulic drive system.。

Hydraulic pump as core component，Hydraulic oil is delivered to the control valve by the oil pump motor，Redistribution to cylinder，And then drive that oil cylinder to realize various actions.。This process，It is the basis of efficient operation of loader.。

Fixed output fixed displacement hydraulic pump

At present, most loaders on the market useFixed displacement hydraulic pump，At work，No matter what the actual need is，Hydraulic oil is delivered in a fixed amount。

This design is simple and direct.，But in practice,，If the motion demand is less than output of the pump，The excess hydraulic oil flows back to the tank，Causing energy waste and oil temperature rise，Affect machine efficiency and life。

Fixed-variable hydraulic pump with output on demand

In contrast，Jingong New EnergyJGM860EThe constant displacement hydraulic pump used in the electric loader is more intelligent and efficient.。By combining the stability of a fixed displacement pump with the flexibility of a variable displacement pump，The precise control of hydraulic oil is realized.，But also reduces the heating of the oil pump motor.。

In the course of operation，Whether it is shovelling operation，Or flexible steering，The system can be based on the actual needs.，Intelligent adjustment of hydraulic oil output，Ensure that every operation is efficient and energy efficient。

Realize green and energy-saving operation mode

The application of the constant variable system of Jingong New Energy has significantly reduced the energy loss.，And that pow utilization rate of the engine is improved.，It really realizes the green and energy-saving operation mode.。

Under complex working conditions，JGM860EAbility to respond more quickly to operating instructions，High compound action efficiency，Demonstrate strong traction and digging force，Bring users higher operational efficiency and lower operating costs！
