What precautions should be taken when starting up the 500-ton four-column hydraulic press?

Precautions for starting up the 500-ton four-column hydraulic press. Today, the editor lists the steps for the normal start-up of the four-column hydraulic press, hoping to help everyone:

       1. Check whether the oil pump, control valve and pressure gauge of the 500-ton four-column hydraulic machine are normal, and whether the oil temperature is within the allowable range;

       2. Check whether there are cracks in the mold and whether the fastening screws are loose;

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

       4. The 500-ton four-column hydraulic press starts the main oil pump motor;

5. Check the oil level of the liquid level gauge of each fuel tank, whether there is oil leakage in each oil circuit and hydraulic pipe fittings, and whether each connecting piece is loose;

       6. Check the deflection of the pressure pointer of the pressure gauge. If it is found to be swinging back and forth or not moving, stop the machine and check the rated pressure of the equipment. Do not exceed the limit when using:

       7. Check and clean other sundries on the working table or mold of the 500-ton hydraulic press:

       8. Adjust the working mode changeover switch to 0 position and perform manual operation to check whether the upper and lower limit switches of the movable beam are safe and reliable, whether there is any abnormal noise in the hydraulic system of the four-column hydraulic press, whether the photoelectric eye, operation button, emergency stop switch, and safety protection device are flexible reliable;

       9. After everything is normal, select the work changeover switch according to the required working mode.
