What are the maintenance and safe operation procedures of the hydraulic press

The correct use of machinery and equipment, careful maintenance and compliance with operating procedures are necessary conditions to extend the service life of machinery and equipment and ensure safe production. Therefore, the structure, performance and operating procedures of the machine should be mastered before use.

Maintenance of hydraulic press:

1. After the oil tank is injected with new oil or replaced with oil liquid, before starting the oil pump first, it must be filled with clean working oil liquid from the oil pump return cup to the pump, otherwise, it is not allowed to start;

2. Start the machine after a long time stop (more than 2 hours), in order to check the operation of the system, the oil pump should be idled for 10 minutes without load, and no abnormal can be operated;

3. After the oil pump starts, the operation can be carried out only after the oil pump starting indicator is on;

4. The oil must be pure hydraulic oil, otherwise, it can be injected into the tank after strict filtration; Note: the amount of oil should not be less than 2/3 of the oil mark height;

5. The first replacement period of the oil in the tank shall not exceed three months, and then the oil shall be replaced at least once a year;

6. The pressure gauge should be checked and corrected once every six months;

7. When the contact area between the die and the working table is small, the cushion plate of appropriate thickness should be installed;

8. The guide column of the movable plate should be lubricated with oil frequently. When working continuously, oil should be injected every 8 hours.

Safe operating rules for hydraulic presses

1. Do not understand the machine structure, performance and operating procedures, shall not open the machine;

2. When the machine has unreliable action, excessive noise, vibration or leakage, it should be stopped immediately to analyze the cause, and it can be restarted after troubleshooting;

3. The machine is not allowed to work under overload or eccentric load;

4. Before the machine works, it should be operated strictly in accordance with the debugging procedure;

5. Electrical equipment grounding is safe and reliable;

6. Hydraulic press Dongguan Kezhong Machinery Technology Co., LTD., system safety valve, master cylinder return safety valve has been adjusted to the safety pressure, the user in the absence of special requirements, shall not adjust;

7. It is strictly prohibited for the movable board to go down. Strictly calculate the clamping height, the height of the mold must be put on the mold with the appropriate thickness of the plate, the parallel degree below the plate is less than 0.1/1000;

The limit travel switch and its bumping block of the movable plate of the hydraulic press can not be adjusted by the user, but its reliability should be checked frequently to avoid accidents; Check method: When the movable board is going down, press the switch, and the downward action should be stopped immediately.
