Precautions for Starting the 500-Ton Four-Column Hydraulic Press

"Today, we have compiled a list of steps for the proper startup of a 500-ton four-column hydraulic press. These precautions are intended to assist you in ensuring a smooth operation. Please pay attention to the following steps:

1. Check if the oil pump, control valve, and pressure gauge of the 500-ton four-column hydraulic press are functioning properly. Verify that the oil temperature is within the allowable range.

2. Inspect the mold for cracks and ensure that all fastening screws are tightened securely.

3. Turn on the power switch of the four-column hydraulic press and start the cooling circulation motor.

4. Start the main oil pump motor of the 500-ton four-column hydraulic press.

5. Check the oil level in each tank, inspect the hydraulic pipelines for any oil leakage, and ensure that all connections are tight.

6. Examine the pressure gauge for the movement of the pressure pointer. If any swinging or lack of movement is observed, stop the machine and inspect the equipment for the rated pressure. Do not operate beyond the specified limits.

7. Check and clean any debris on the working table or mold of the 500-ton hydraulic press.

8. Set the working mode switch to the 0 position, perform manual operations, and check the reliability of the limit switches on the moving crossbeam. Verify if there are any abnormal sounds in the hydraulic system of the four-column hydraulic press, and ensure that the photoelectric eye, operation buttons, emergency stop switch, and safety protection devices are flexible and reliable.

9. After ensuring everything is in order, select the desired working mode using the mode switch.

These precautions are crucial for the safe and efficient operation of the 500-ton four-column hydraulic press. Please adhere to these steps diligently to prevent any potential issues during startup."
