One: Prepare:
1. Check the amount of hydraulic oil before use. The height of the hydraulic oil is 2/3 of the lower base. When the amount of oil is insufficient, it should be added in time. The oil must be finely filtered before injection. Add pure 20 # hydraulic oil to the oil hole of the lower base. The oil level is seen by the oil level rod, which is usually added to the height of 2/3 of the lower base.
2. Check the lubrication between the column shaft and the guide rail, add oil in time to maintain good lubrication.
3. Turn on the power, move the operating handle to the vertical position, close the oil return port, press the motor start button, the oil in the oil pump enters the oil cylinder, drive the plunger to rise, when the hot plate is turned off, the oil pump continues to supply oil When the oil pressure rises to the rated value (14.5MPa), press the positioning stop button to put the machine in a stop pressure state (that is, timed vulcanization). After the curing time is reached, move the handle to lower the plunger to open the mold.
4. Temperature control of the heating plate: when the rotary button SA1 is turned off, the plate starts to heat, and when the temperature of the plate reaches a preset value, the heating automatically stops. When the temperature is lower than the set value, the board is automatically heated, and the temperature is always the set value.
5. Action control of the vulcanizing machine: press the motor start button SB2, the AC contactor is energized, and the oil pump works. When the hydraulic pressure reaches the set value, the AC contactor is disconnected and the vulcanization time is automatically recorded. When the pressure drops, the pump motor starts automatically. Press to reach the set vulcanization time, the sounder will beep to inform that the vulcanization time is up, you can open the mold, press the stop button, move the manual operation valve, and then lower the plate for the next cycle.
Two: hydraulic system
1. The hydraulic oil should use 20 # mechanical oil or 32 # hydraulic oil, and the oil must be finely filtered before refueling.
2. Regularly release oil for sedimentation and filtration, and clean the oil filter at the same time.
3. All parts of the machine should be kept clean, and the column shaft and the guide frame should be regularly lubricated to maintain good lubrication.
