According to the installation location can be divided into top-mounted, side-mounted and under-mounted. Mounted on the fuel tank to the pump and other equipment installed in the stiffness of the cover plate of the hydraulic pump better repair, compact structure, the most widely used. But it can also be cast on the tank shell cooling fins hydraulic agents, enhance heat dissipation, which increases the service life of the pump. Side-mounted fuel tank is to pump the tank and other devices installed next to the pump, an area is great, but the installation and maintenance easy pump sales, usually in the larger system flow and fuel tank capacity, especially when a tank use oil to more than one pump. Because the side-mounted fuel tank level is higher than the pump suction port, it has a better suction effect. Cause: (1) hydraulic oil tank is too low; Remedy: Add hydraulic oil Cause Failure: (2) No seasonal use of hydraulic oil; Remedy: usually applied 46 # hydraulic oil (or 68 #), no need for special replacement When special cold northern winter, consider using 32 # Fault reasons: (3) into the pipeline was severely clogged dirt; Remedy: Remove the foreign body Cause tube failures: (4) oil pump drive gear oil seal is damaged, the air into the hydraulic system; Remedy : or damaged seals replace aging, O-ring source of hydraulic pumps, hydraulic pumps, hydraulic pressure from Jinan Jing Jing Chong Chong Hydraulic Machinery Limited.
