A Comparative Study of Two Common Pump-Controlled Hydraulic Circuits for Single-Rod Actuators

Pump-controlled hydraulic circuits are proven to be more efficient than conventional valve-controlled circuits. for double rod cylinders well developed and in use many practical applications. Existing pump-controlled single-rod actuators experience oscillation issues under specific operating conditions; that is identified as a critical zone on the load-velocity plane. The challenge these find out proper way compensate differential flow at both sides of cylinder all conditions. two main types valves commonly used by researchers, circuits, are: pilot-operated check valves, shuttle valves. In this research, performance comparison between equipped with either terms size oscillations’ characteristics, was accomplished. Simulation studies showed utilize possesses smaller oscillatory zones less severe oscillations, when compared Experimental work verified simulation results proved accuracy mathematical models. Hence, recommended basic platform further efforts solve problem
