How to maintain HDPE Pipe Making Machine

1. Cleaning work
Body cleaning: After each production is completed, wipe the surface of the machine with a clean rag to remove dust and plastic particles. For difficult-to-clean parts, such as the bottom and corners of the machine, you can use small cleaning tools such as brushes or vacuum cleaners. Keeping the appearance of the machine tidy not only helps to be beautiful, but also facilitates and timely discovers abnormalities on the surface of the machine.
Regularly deep clean the inside of the machine. Especially the screw and barrel of the extruder, which are the parts that directly contact the raw materials. When the machine is stopped, wait for the temperature to drop, use special cleaning agents and tools to carefully remove the residual HDPE material on the screw and barrel. The residual material may deteriorate and affect the quality of the next pipe production.
Mold cleaning: The cleaning of the mold is crucial. After each use, disassemble the mold and clean it with a suitable solvent to ensure that the flow channel inside the mold is not blocked. Because the blockage of the mold flow channel will cause uneven extrusion of the pipe, affecting the quality and appearance of the pipe.
2. Component inspection and maintenance
Key component inspection: Regularly check the wear of the screw, barrel and mold. Wear of the screw and barrel will affect the conveying and mixing of materials, while wear of the mold will cause deviation in pipe size and deterioration in surface quality. Check the key dimensions with measuring tools, and replace the parts in time when the wear exceeds the allowable range.
Check the heating and cooling systems. The heating system should ensure that the heating elements work properly and the temperature control is accurate. The cooling system should ensure that the water pipes are leak-free and the cooling efficiency is good. For the sensors in the heating and cooling systems, they should be calibrated regularly to ensure the accuracy of temperature monitoring.
Maintenance of moving parts: Maintain the transmission parts of the machine, such as motors, reducers, chains or belts. Add lubricating oil regularly to reduce friction and wear. Check whether the operating current and voltage of the motor are normal to prevent the motor from overloading. At the same time, check the tension of the chain or belt. Too loose or too tight will affect the normal operation of the machine.
3. Long-term maintenance measures
Equipment rust prevention: For the metal parts of the machine, especially those that are exposed to the outside for a long time, rust prevention should be done well. Apply anti-rust oil or anti-rust paint on the surface of the equipment to prevent rust and corrosion of metal parts. Especially in humid environments, anti-rust measures should be strengthened.
Equipment storage: If the equipment needs to be stored for a long time, place it in a dry and well-ventilated place. Before storage, thoroughly clean and maintain the equipment, and apply protective oil to key parts such as screws and barrels to prevent rust. At the same time, cover the equipment with a dust cover to avoid dust accumulation.
