Abstract:Traditional hydraulic pump test-bed consumed more energy, and in order to simulate the load, pressurized by the throttle opening, high pressure oil flows back to the tank, resulting in a lot of energy is wasted. Through the test-bed circuit redesign and recovery test pump high pressure oil and the oil pump to drive hydraulic motor together, by a hydraulic motor to drive the pump, the recovery of energy utilization was realized. By using simulationX to simulate and analyze the new circuit, the performance test of the pump was carried out under the condition of keeping the original working condition of the test pump. The energy saving is more than 67%.
