A2F6.1 piston pump / motor Features: dip a large element: All specifications are the same 40 ° angle of the hydraulic pump maintenance, given a high power, the weight of relatively small size pump sales, the best efficiency and the structure of the economy. With two seals overall tapered piston pump maintenance, patent Cardiff cardan shaft drive cylinder. Ease of installation and maintenance of the bearing structure, providing longer life. New levels of modern design standards series. Special modifications series 1-4 series have the same hydraulic connector, flange and shaft specifications. Constant Control Priorities in pilot pressure control, pressure control and constant voltage control pilot can not control the motor, when the motor constant working pressure is lower than the set pressure, the pilot pressure the motor entirely controlled by the system; when the motor After working pressure reaches the set pressure constant, constant pressure control servo valve motor will be automatically controlled. Mainly by adjusting the control lever 1 knot, 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 one-way valve. Constant pressure control servo valve consists of a control valve housing, control spool, the spring and the adjusting screw and other components. Maintenance of hydraulic pumps, hydraulic pumps, hydraulic preferred by the Jinan Jing Jing Chong Chong Hydraulic Machinery Limited. Jinan Jing Chong Hydraulic Machinery Co., Ltd. (www.jnjcyy.com) (www.jnjcyy.com) strong, credible, in Jinan, Shandong mining machinery industry has accumulated a large number of loyal customers.
