Cone crusher hydraulic system is an important part of the cone crusher, hydraulic system has a small size, light weight,construction waste crusher easy to install, power density, fast response, control and other advantages. Cone crusher hydraulic system through a pump, an auxiliary pump and two hydraulic motors to achieve the main function of the crusher, hydraulic system failure will directly lead to the failure of the entire drive system, resulting in significant losses. The hydraulic cylinder is a key component that provides crushing pressure and clearance stroke, so the hydraulic cylinder with the cone crusher must be step by step. 1, the joint bearing 2 installed in the lower side of the rack hydraulic cylinder hanging ear hole in the middle of the location; 2, the hydraulic cylinder ears inserted into the lower part of the rack between the lifting ears, sand making machine insert the small axis. The small shaft should be installed in a cool way. Tighten the small shaft with a top wire. Note that the top wire should be in the annular groove on the small shaft; 3, the nozzle installed in the small shaft; limit nut to the bottom of the piston rod screw; ultrafine mill lift the hydraulic cylinder so that the piston rod through the support sleeve openings; 4, the joint bearing 1 set in the piston rod and on the support sleeve on the joint bearing support hole; 5, through the wire lock lock nut position; 6, the accumulator, pipe joints, combined gasket and hydraulic cylinder connection; 7, the hydraulic connection hose and access to the oil pipeline connection.
