First point: Preheat the hydraulic oil. If the temperature of the hydraulic fluid in the blow molding machine tank is too low, the heater should be turned on immediately, usually on a large machine.
The second point: press the start button and stop immediately, check whether the running direction of the pump is correct. If it is found that it does not correspond, immediately change the power line of the two-phase receiving motor.
The third point: the machine should be turned on without pressure on the hydraulic system. When turned on, adjust the pressure of each pump's overflow system to a safe pressure. In large-scale injection machines, there are often two pressure systems, one is the clamping unit and the other is the injection unit, and each unit has a pressure-receiving space. After the pump is stopped, this pressure vent valve must be opened. When the pump is working, the pressure vent valve must be closed.
