Winter maintenance of extrusion equipment
The specific measures are as follows:
1. Thoroughly clean all dust from the electrical components inside the electrical control box, focusing on the inverter, speed regulator, and PLC. Use compressed air to blow air into the components, but make sure there is no moisture. Tighten loose cables and wire connectors; check the cable insulation. Replace aging or poorly connected components promptly.
2. Record the rated parameters on the computer screen and check them before starting the machine next time. If any differences are found, enter them according to the recorded data.
3. Check the front and rear grease fittings of the main motor and replace them with grease. Check the plum blossom pads of the coupling for damage. Check the reduction gearbox for abnormal noise and refill and replace the gear oil. Open the reduction gearbox and carefully clean the moving parts and the housing, clean the bearings, and replace the lubricating oil.
4. Clean the water channels of the main engine and drain the accumulated water in the water inlet and outlet systems to prevent the pipes from bursting in the cold winter.
5. Check the cleanliness of the water lines in the mold core cooling copper pipes. Drain any accumulated water from the water pump, vacuum pump, and all filters to prevent rust and cracking of the pump blades. After shutting down, clean the material between the die core rods. Apply anti-rust oil to the feed port and seal it with stretch film.
6. Check all moving parts of the equipment for adequate lubrication. Especially for frequently used components such as screws, rollers, bearings, and guide posts, check to prevent low temperatures from causing moving parts to seize and affect normal production. Bearings and universal joints should be lubricated regularly.
7. Check and calibrate instruments that display pressure, current, voltage, meters, etc.; check the heating conditions of each heating element and replace damaged heating and sensing elements.
8. Before shutting down the machine, empty the material inside the screw to prevent material backflow during the next startup. Remove the screw and oil the screw barrel to prevent rust and corrosion. Disassemble and clean the screw, barrel, and die as necessary; measure the screw's outer diameter; and inspect the barrel's inner wall and die for wear and scratches. Grind and trim any scratches and burrs on the working surface until it is smooth and free of material buildup.
9. Before starting the machine next time, please use a multimeter to measure whether there is a short circuit between the three-phase wires and between the three-phase wires and the ground to prevent mice from biting the wires and causing a short circuit.
10. Lubricate all sprocket chains and perform rust-proof treatment on all exposed and rust-prone parts.
