Liyuan Hydraulic / A2FE160 products for the swash plate type (straight shaft axial) quantitative hydraulic piston motor is a hydraulic energy into mechanical energy. And LY-XJ0177-1 rotary gear coupling to use. This product has a structure Guizhou simple pump, small size and other characteristics, installation dimensions and the same type of imported products consistent, pump maintenance background noise for open hydraulic system widely used in various hydraulic excavator slewing mechanism, with braking device. Variables The oil pressure piston pump, the pump housing variable housing through hole through the check valve into the variable housing lower chamber, when the downward movement of the lever, push downward movement of the servo piston pump, servo valve the valve port open, the oil pressure of the lower chamber of the housing Variables piston through the hole into the superior vena variable case, since the upper chamber area larger than the lower chamber, hydraulic pressure pushes the piston downward movement, led pin the variable head around the ball rotates pump sales, change the variable head tilt angle (increase), piston pump flow increases. On the other hand lever upward motion, tilt angle variables change in the opposite direction head, pump flow also changes. When the tilt angle changed to zero after the variable angle head in the negative direction change, reversing the flow generation, pump out the oil port transformation. Variable displacement hydraulic pumps, hydraulic creating crystal quality assurance (certification), the hydraulic pump from Jinan Jing Chong Hydraulic Machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd. (www.jnjcyy.com) (www.jnjcyy.com) Shandong Jinan, mining machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. In the crystal creating hydraulic leadership with the staff warmly welcome all inquiries negotiations to create the crystal creating hydraulic better future.
