1. When the four-column hydraulic press system is working, it must be shut down first. When the pressure is not relieved or the control circuit is not disconnected, it is strictly prohibited to repair the four-column hydraulic press to avoid personal accidents.
2. The maintenance site must be kept clean. Surface debris must be removed before disassembling components or loosening pipes. During the maintenance process, all possible access openings must be sealed with clean covers immediately to prevent pollutants from penetrating into the four-column hydraulic press. System software cannot be polished, constructed or welded at the maintenance site.
3. When replacing new electronic equipment, it must be kept clean and free of sand, stains, welding scars, etc. It can be soaked directly before construction.
4. When disassembling and replacing the hydraulic seal, do not use sharp special tools, and be careful not to damage the hydraulic seal and working surface.
5. When disassembling and assembling dissolved hydraulic parts, pay attention to the direction and order of the parts after disassembly and assembly, keep them properly, do not lose them, and do not hit the deep processing surface. When installing components, each component must be clear and neat.
6. When assembling the components of the four-column hydraulic press, the torque should be uniform and moderate to avoid deformation of the oil circuit board, jamming of the valve body or leakage of the joints.
7. When disassembling, replacing or filling hydraulic oil, the hydraulic oil must be introduced into the tank according to the high-precision oil filter truck. The hydraulic oil model must meet the requirements during work. Gear oil should be maintained regularly to ensure the normal operation of the hydraulic transmission system. The hydraulic oil removal and replacement period should vary depending on the type of hydraulic oil, office environment and operating conditions. Generally speaking, the time for disassembly and replacement of hydraulic oil must be reduced in places with continuous operation, continuous high and low temperatures, and large dust.
8. After maintenance, the maintenance part of the four-column hydraulic press must be determined. According to the technical specifications for debugging the hydraulic press system, make adjustments after confirmation. Observe the maintenance location and make sure it is normal before it can be put into use.
