Based on the simulation model of quick drop valve flow regeneration measurement data, the influence factors of quick drop valve are analysed through two orthogonal experimental designs to obtain the optimal combination of the efficiency of oil filled â for flow regeneration. Simulation and experimental verification results show that: In the structure of the original quick drop valve, through the range R, the influence factor valve opening C has the greatest influence on the efficiency of oil filled â.The efficiency of oil filled â of the optimal combination A1A2A3 is 78.9% lower than the standard requirement of 85%. Based on the method of controlling the oil return variable according to the load feedback and orthogonal experimental design, the improved structure makes the efficiency of oil filled â for flow regeneration increase from 57% of the measured data to more than 85% of the measured verification. Through 1000 hours performance verification, the performance of the quick drop valve is stable, no failure rate, and the efficiency of oil filled â is still higher than 85%. At the same time, the efficiency of the earth-moving work after the quick drop of the blade is increased by more than 28%.
