Highland LPV90 series Wheat harvester Hydraulic Motor Pump System information:

Harvester Hydraulic Motor Pump System basic introduction:

Highland Harvester Hydraulic Motor Pump System are typical volumetric fluid machine, driven by the prime mover, converting the input mechanical energy into the pressure energy of the liquid, and then inputting it into the system in the form of pressure and flow. It is the hydraulic power source of the hydraulic system. Because it can transport liquids under high pressure, it is widely used in in agricultural machinery such as wheat harvester.

Hydraulic motor pump system user shall ensure that the hydraulic pump uses the correct formulation of the medium to ensure the cleanliness of the operating medium of the equipment, and shall not contain solid particles.
