Volume control circuit of variable displacement pump and hydraulic cylinder

The characteristics of the loop: the variable pump can be used for direction and speed, the pressure and flow of the pump can be adjusted according to the load and speed of the hydraulic cylinder.

Function: by changing the displacement of the pump to change the movement speed of the hydraulic cylinder;

Application scope: suitable for large power hydraulic systems such as forging machinery;

Loop selection principle and note: two overflow valve 1, 2 for safety valve with. Two check valve 3, 4 do not use for self suction and fill oil - manual valve 5 to the pressure pump unloading, or to the hydraulic cylinder in a floating state.
