Variable oil pump expensive and sensitive, in the first manipulation and routine maintenance should note the following: the pump oiling: Before 啔 oil pump, fuel injection from the fuel inlet into the pump until it filled up. If you start the pump before oiling, it may be due to insufficient lubrication failure. Pump can not be reversed: Note electrical wiring, reverse may damage the pump. Low-speed low-pressure test run: Repeat start and shut down the motor, the pump and the suction is released in the air. Ten percent of the input pressure and flow, open radio station forward and backward movement, so that the exhaust gas flow and pressure valve. Ten minutes after the operation, such as hydraulic oil system maintenance no abnormal sound, you can boot. If you stop using the machine again after a period of use, also need such a boot. Hydraulic oil used: hydraulic oil hydraulic oil viscosity selection 20-200Cstnian recommended 30-50cST high viscosity hydraulic oil. When the oil temperature is below 5 degrees hydraulic pump sales, deal with hydraulic oil for heating. Cleanliness of hydraulic oil should be kept in NAS10 below should be cleaned every three months back to the oil filter cartridge pump to keep the oil flow and clean. Maintaining the oil level in the oil ruler bit more: when the oil level is too low, the hydraulic oil is contained in the air release is not sufficient, so that a greater noise and damage the pump. Dual axial piston variable pump A8VO - structure variable swash plate double pump with two axial tapered piston rotary assembly for open loop hydrostatic drive - traffic and drive speed and displacement is proportional to the hydraulic pump repair, and may qv max and qv min = stepless adjustment between 0 - pump is suitable for direct mounting on the engine flywheel housing - auxiliary pump and two loops share a suction port - a variety of control equipment, a variety of control and regulation functions - min Power Control - Built-in auxiliary pump with pressure relief valve, the valve can take - driving output can be mounted axial piston and gear pumps - power to weight ratio - Long life pump maintenance, crystal create hydraulic quality assurance (certification), the hydraulic pump from Jinan Jing Chong Hydraulic Machinery Limited.
