Adjusting the amount of motor control folding Edit this paragraph adjustment control junction primarily by the lever 1, the regulator housing 2, variable piston 3, the pilot pressure control servo valve 4, the regulator spring 5, the feedback spring 6, the regulator guide rod 7, constant pressure control servo valve assembly 8 and the check valve. Constant pressure control servo valve consists of a control valve housing, control spool, the spring and the adjusting screw and other components. 1. Pilot pressure control works displacement of maximum displacement motor starting, repairing the hydraulic motor when the working pressure is lower than the set pressure valve 7, valve 7 can not afford to control the role of the hydraulic motor, the motor displacement with X port pilot control changes in pressure and infinitely variable between maximum and minimum, enabling the pilot pressure control. Liyuan Hydraulic motors, hydraulic fluid can enter through the check valve variable cylinder chamber 5 when the small motor A, B either work to provide pressure oil when the oil port. When X port pilot control pressure increases, pilot pressure oil acts on the valve 1 regulator spring force to overcome the force of the spring 2 and 3, and pushes the valve 1 is moved to the right hydraulic motor maintenance | hydraulic motors | hydraulic factory direct crystal Chong from Jinan Jing Chong Hydraulic Machinery Limited.
