Loader fixed-variable hydraulic system

Technical characteristics

When standby state, variable pump minimum displacement, fixed pump low pressure unloading, reduce pressure loss；

The steering system is supplied by the variable pump, and the pump output flow size depends on the load requirements；

Shift to priority. Variable pump priority to supply oil to the steering system to ensure the safety of the loader；

Fixed pump and variable pump on-demand combined shunt oil supply work system，When the flow rate is small, only the fixed pump supplies oil to the working system. When the load demand flow increases, the fixed pump and the variable pump combine to supply oil to the working system, which not only ensures the working efficiency of the loader, but also has energy saving effect；

Full variable characteristics，Variable pump flow and the output flow of the fixed pump after the flow control valve, fully matched flow demand；

The fixed-variable hydraulic system is more efficient than the fixed-pump system, especially in low-flow conditions, with significant energy savings。
