Powerjet extrusion blow molding machine downtime maintenance guide
1: Mold, make the mold on the machine in the mold-opening state, and spray mold anti-rust agent on all mold cavities.
2: Set the clamping pressure to a lower level (about 15bar) and perform the clamping action until the mold is closed. The blowing nozzle is also sprayed with mold anti-rust agent.
3: Guide post (rail), apply a small amount of butter to the exposed guide post (rail) and the protruding piston rod to prevent rust or condensation.
4: Remove the accumulations on the motor and fan cover, remove the dust filter from the air inlet of the electric box, clean the dust, and put it back in place.
5: Drain the cooling water, close the cooling water inlet and outlet valves, unplug the inlet and outlet ends of the cooling water pipes connected to the machine or mold, and lay the ground flat to drain the internal cooling water. However, the compressed air is blown from one of the inlet and outlet ends, so that the internal water is completely discharged from the other end.
6: Stop extruding, and hollow out the excess plastic in the hopper, and drain the material in the barrel until it cannot be discharged.
7: Electrical protection, check the inlet and outlet holes and ventilation holes of the electrical box and the machine trunking, and block the holes to prevent rats from entering. The electrical box door ensures that it is closed securely.
8: Close the machine, close and fasten all the protective doors and safety doors of the machine.
9: Cut off (close) the water supply, power supply, and gas supply switch (valve) of the machine.
10: Stop the auxiliary machine, turn off the cooling circulating water pump, turn off the air compressor, close the water supply valve of the cold water system, and discharge the compressed air to normal pressure.
