Pipe extrusion line is a new type of green pipe formed by extruding composite anti-corrosion, hygienic, non-toxic inner and outer plastic layers on the surface of thin-walled welded pipes. It has the characteristics of corrosion resistance, high pressure bearing, small fluid resistance, long service life, low cost and wider application range.
The pipe extrusion line is mainly used for low-speed heavy cutting or high-speed light cutting, and the rigidity of the CNC pipe extrusion line, the self-protection device of the CNC pipe extrusion line, the tool magazine of the CNC pipe extrusion line, and the CNC pipe extrusion line must also be considered. Production line control system. As long as users fully understand these five parts, they can buy a suitable pipe extrusion line.
When the pipe extrusion line is in use, there will be a little plastic residue in key parts, such as the machine head, water tank, mold, etc., and there will be residues in the mold and the machine head after molding and during the shutdown process. Therefore, the first task after shutdown is to maintain these parts.
When maintaining the equipment, the power supply of the equipment must be disconnected to ensure the safety of the operator. The pipe extrusion line should not be maintained with brute force. It should be cleaned by rotating operation according to the principle of the pipe extrusion line equipment, and the dirt cannot be removed forcefully.
1. Residential use: cold, hot water and heating of houses and villas.
2. Public buildings: water supply and floor radiant heating for public buildings such as office buildings, markets, theaters, and military camps.
3. PVC pipes for transportation facilities: piping for airports, passenger stations, parking lots, garages, and expressways.
4. For animals and plants: piping in zoos, botanical gardens, greenhouses, chicken farms.
5. Sports facilities: cold and hot water pipes for swimming pools and saunas.
6. Sanitary use: piping for water supply pipes and hot water pipes.
7. Others: industrial pipe extrusion line water pipes.
PVC pipes have good mechanical properties and excellent corrosion resistance. They are light in weight during use, easy to install, and require no maintenance. However, using steel as sewer pipes for public works is easy to corrode during use and must apply paint frequently, so that the maintenance costs are high.
Generally, metal pipes for construction and public works need to be replaced in about 20 years, while PVC pipes with good processing have a service life of up to 50 years. Therefore, PVC pipe is a good plastic product with low production cost, high strength and corrosion resistance.
This machine is equipped with a quantitative feeding device, so that the extrusion amount and the feeding amount can be matched to ensure the stable extrusion of the product.
Due to the characteristics of the conical screw, the feeding section has a larger diameter, and the heat transfer area and shear speed of the material are relatively large, which is conducive to the plasticization of the material. The high shear rate enables the extrusion line melt to be extruded at a lower temperature.
When the screw rotates in the barrel, the PVC mixture is plasticized and pushed to the head, and the pipe is extruded into the production line to achieve compaction, melting, mixing and homogenization; and the purpose of exhausting and dehydrating.
The feeding device and screw drive device adopt frequency conversion speed regulation, which can realize the synchronous speed regulation of the pipe extrusion line.
