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 rate of the hydraulic pump sales, open radio station forward and backward movement, so that the exhaust gas flow and pressure valve. Running ten minutes later, as the hydraulic system no abnormal sound, you can boot. If you use the pump to repair the machine again to stop using for some time, also need such power. 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, to deal with the 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, 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. _ Crystal create a hydraulic pump maintenance quality assurance (certification) _ pumps from Jinan Jing Chong Hydraulic Machinery Limited.
