1. The oil pipe shall be prevented from bending under operating pressure. The oil tank connecting the oil pump and the jack shall be kept clean. When it is not in use, it shall be blocked with screws to prevent sediment from entering,
The oil nozzles exposed by the oil pump and Jack shall be sealed with nuts to prevent dust and sundries from entering the machine. After daily use, the oil pump shall be wiped clean to eliminate the oil dirt on the oil filter copper wire cloth.
2. The oil pump and Jack shall use regular oil number operating oil, generally No. 10 or No. 20 mechanical oil, or other adjacent hydraulic oil, such as transformer oil.
Hydraulic pump maintenance
The oil filled into the oil tank must be filtered. The filter shall be conducted once a month when it is often used, and the oil tank shall be cleaned regularly. Generally, the oil level in the oil tank shall be maintained at 85%,
In case of lack, compensation shall be made in time, and the compensated oil shall be the same as the oil number in the original pump. The oil temperature in the oil tank should generally be 10 ~ 40 ℃, and should not be used under negative temperature.
3. Grounding power supply: it is necessary for the cabinet to be grounded. The trial operation can be carried out after checking the insulation of the line.
4. The oil pump should not be operated under overload. The pressure of the safety valve must be adjusted according to the rated oil pressure of the equipment to prevent arbitrary adjustment.
5. When the oil pump stops operation, the oil return valve shall be slowly loosened first, and after the pressure gauge gradually returns to the zero position,
The oil pipe joint nut of the jack can be removed. Do not remove or replace the oil pipe or pressure gauge under load.
