| Abstract: | Taking the high pressure elevation-stopping problem of ta pressure machine hydraulic system as an example and based on analysis,research and measuring,this paper demonstrates the main reasons causing problem of over-length time when the status change is made from system unlaading into high pressure overflow of the pilot relief valve by remote control.Given the conditions that the structure of the pilot relief valve is unchanged, a solution is proposed to solve the mentioned problem by modification of the return system and the practice has been proved of relatively good effect. |
