摘要

Experimental studies of counterbalance valve for the hydraulic drive control systems of mobile machines are presented. According to the results of theoretical research experimental prototype of the counterbalance valve is developed. Experimental stands are elaborated, where leak tightness degree was studied and static characteristics were obtained. Dependences of operating fluids supply on the parameters of the pressure difference at its basic spool and load pressure are plotted. Transient processes in the hydraulic drive control system are analyzed, adequacy of the theoretical calculations to the elaborated mathematical models for the control system of mobile machine hydraulic drive is proved.
