The hydraulic system is the power source for the section bending of the profile bending machine, and its good working condition determines the quality and speed of the section bending. Correct use and reasonable maintenance and repair of the hydraulic system can not only extend the service life of the profile bending machine, but also reduce the maintenance cost.
The following is about the daily maintenance of the hydraulic system of the profile bending machine:
Hydraulic oil circuit
a. Check the oil level of the oil tank every week. If the hydraulic system is repaired, it should also be checked. If the oil level is lower than the oil window, add hydraulic oil;
b. The hydraulic oil used in this machine is No. 46 anti-wear hydraulic oil;
c. The oil should be changed after the new machine has been working for 2000 hours, and the oil should be changed every 4000 to 6000 hours after work, and the oil tank should be cleaned every time the oil is changed;
d. The oil temperature of the system should be between 35℃～60℃ and not exceed 70℃. If it is too high, it will cause deterioration and damage of oil quality and accessories.
a. The filter should be replaced or thoroughly cleaned every time the oil is changed;
b. The machine tool has related alarms or other filter abnormalities such as unclean oil, which should be replaced;
c. The air filter on the fuel tank should be inspected and cleaned every 3 months, and it is best to replace it every year.
a. Clean hydraulic components (base plates, valves, motors, pumps, oil pipes, etc.) monthly to prevent dirt from entering the system, and cleaning agents cannot be used;
B. After using the new machine for one month, check whether the bending of each tubing is deformed. If there is any abnormality, it should be replaced.
After two months of use, all fittings should be tightened. The system should be shut down during this work.
