Safe operating procedures for hydraulic presses

Safe operating procedures for hydraulic press operators to guide the correct operation and use of equipment.

1) safety Operation Regulation

1.before starting the machine, check whether the fasteners are reliable, whether there are obstacles in the running parts and sliding surfaces, and whether the limit device and safety protection device of the single-column hydraulic press are reliable.

2.cylinder piston jitter or oil pump sharp sound, should be discharged gas.

3.strictly prohibit the use of cylinder stroke, pressure or pressure relief in the process of shaking.

4.the hydraulic press maintains the hydraulic oil quality, the working oil temperature is not allowed to exceed 45 ° C, if appears the unusual, the hydraulic press then stops.

5.strictly prohibit random control valve and pressure gauge, hydraulic machine should regularly correct pressure gauge.

2) operating regulation

1.before starting the hydraulic press, check whether the fasteners are reliable, whether there are obstacles in the running parts and sliding surfaces of the hydraulic press, whether the limit device and safety protection device are perfect.

2.after work off-duty should first close the working oil pump, then close the control oil pump, cut off the power, wipe clean equipment, Make Good Point Inspection Records.

3.before work, test run for 10 minutes, check the buttons, switches, valves, limit devices and other flexible and reliable, to confirm the normal pressure of the hydraulic system, work beam movement flexible, before starting the hydraulic machine work.

4.work if the equipment abnormal phenomenon or sound should be stopped to check.

5.cylinder piston found jitter or pump sharp noise must be discharged gas. When working, the pressed workpiece of the hydraulic press should be placed in the middle of the worktable with the spindle concentric, and the pad is placed smoothly.
