Plastic Pipe Equipment can also be referred to as plastic pipe production line, plastic pipe equipment is an important part of the chemical building materials, with its excellent performance, health, environmental protection, low-power consumption and so on for the vast majority of users of the wide acceptance.
Plastic Pipe Equipment Composition
Pipe production equipment has a control system, and then through the extruder, head, shaping and cooling system, haul-off machine, cutting equipment and turning frame composition. Each pipe production line has two screw extruders, the main one is an expander that uses power transmission bushings and high efficiency screws, and the other is a smaller extruder that extrudes a marker line. Plastic pipe production line failure, which will lead to plastic pipe surface roughness, internal jitter ring, no vacuum and other phenomena, so quickly eliminate plastic pipe production line failure, can improve the quality of the product.
Classification of plastic pipe equipment
Plastic pipe production has PE pipe equipment and PVC pipe equipment. PE pipe equipment has a special structure, has a high degree of automation, easy to operate, continuous production is stable and reliable. Plastic pipe production line production pipe has moderate rigidity, strength, good flexibility, creep resistance, environmental stress cracking properties and better heat satisfaction properties, a city natural gas transmission pipeline and outdoor pipeline preferred products must be it.
Plastic pipe structural design
PE pipe equipment head adopts the most advanced basket head or spiral shunt extrusion composite head design, easy to adjust, the material is extruded uniformly, the calibrating sleeve adopts a unique grooving process and water ring cooling, to ensure that the pipe molding accuracy.
PE pipe production line with polyethylene high-efficiency screw, slotted barrel with strong water jacket cooling, greatly improving the transmission capacity to ensure effective extrusion; high torque reducer vertical structure; DC drive motor. Suitable for polyolefin processing, the basket type composite die not only ensures high efficiency extrusion stability, but also low melt temperature, which can realize the minimum pressure and bring the highest pipe quality. High-vacuum dual-chamber diameter setting technology and spray cooling water tank, improve the output of the pipeline to meet the needs of production at high speeds. Crawler traction machine, smooth traction force, each traction driven by independent AC servo motor, and digital controller control drive technology for accurate, speed regulation to achieve a high degree of synchronization. Adopt high speed, accurate design cutting machine, cut section level, and equipped with a powerful chip suction device, will be reduced to a minimum of maintenance work.
PVC pipe equipment has the function of raw material mixing; extruder part to ensure stable extrusion of products, the PVC mixture plasticized and pushed to the head; extrusion die head part, is the pipe molding of the key components; vacuum shaping water tank for pipe shaping, cooling; haul-off machine is used for continuous, automatic molding pipe from the head of the machine out of the lead; cutter for automatic cutting; turning material frame to achieve Turning over the material to achieve the purpose of unloading.
PVC pipe equipment function has the use of PVC resin powder as the main raw material for the production of pipe such as pipe.
Plastic pipe failure maintenance
Inevitably in the production of plastic pipe equipment, there will be some failures, such as: the outer surface of the plastic pipe is rough and not smooth, we must adjust the process temperature in a timely manner; the outer surface of the plastic pipe gouge, adjust the calibrated set of water pressure, the amount of water required to be balanced; the inner surface of the pipe gouge, check the inner pipe whether the water, reduce the internal temperature of the mold; pipe internal shaking ring, the pipe is a good idea, but it is not a good idea, it is a good idea. ; pipe internal jitter ring, adjust the sizing set of water, so that its water uniformity; no vacuum, check whether the vacuum pump inlet is clogged; pipe wall thickness is not uniform, adjust the wall thickness in the mold; cutting inaccurate counting, check whether the counting wheel is pressed, etc., it must be more timely discovery, view and deal with.
Plastic pipes also have common problems: First, the tensile strength and toughness is poor, often showing brittle, low elongation and easy to break. Second, poor impact resistance, even 10 impact, all rupture. Third, the softening temperature is low, easy to heat deformation, reducing the impact resistance of the pipe, tensile strength, toughness.
For the plastic pipe problem, the production should be in the choice of additives, raw material ratios, production processes, and production equipment, pay more attention to and input, can not be treated lightly, to be dealt with seriously.
