Qingdao Haixi anticorrosive insulation equipment tells you: the production process of plastic pipe equipment will inevitably appear some faults

Plastic pipe production line, plastic pipe equipment is an important component in chemical building materials, with its excellent performance, health and environmental protection, low power consumption and other characteristics of the majority of users widely recognized.

The composition of plastic pipe equipment
Tubular production equipment consists of extruder, head, shaping cooling system, tractor, cutting machine, turning frame and so on. There are two screw extruders on each pipe line, one of the main extruders is made of conductive sleeve and efficient screw, and the other is a small extruder with marked extruder line. Failure of plastic pipe production line will cause the surface roughness of plastic pipe, internal vibration ring, no vacuum and other phenomena, so quickly eliminate the failure of plastic pipe production line, can improve product quality.

Classification of plastic pipe equipment.

Classification of plastic pipe equipment production of PE pipe equipment and PVC pipe equipment. Polyethylene pipe equipment unique structure, high degree of automation, simple operation, continuous production stable and reliable. The pipeline produced by plastic pipe production line has moderate stiffness, strength, good flexibility, creep resistance, environmental stress cracking performance and good thermal satisfaction performance, which is the first choice of urban gas pipeline and outdoor pipeline.

Plastic tube structure design.

The head of polyethylene pipe equipment adopts advanced spherical head or spiral split extrusion pipe composite head design, which can be easily adjusted, the extrusion material is uniform, the sizing sleeve adopts unique grooving technology, water ring cooling, to ensure the precision of pipe forming.

Polyethylene pipe production line using polyethylene screw, slotting machine barrel, strong water jacket cooling, greatly improve the conveying capacity, ensure effective extrusion; High torque reducer vertical structure; Dc drive motor. The utility model is used for polyolefin processing basket form composite mold, which has high extrusion efficiency and stable, low melting temperature, small pressure and high pipe quality. High vacuum double cavity diameter setting technology and jet cooling water tank are adopted to increase pipeline output and meet high production speed. Track towing, towing smoothly, each towing device is driven by independent AC servo motor, digital controller control towing technology accurate, speed adjustable, achieve high synchronization. Design high cutting speed, cutting section height precision, and equipped with a strong chip absorption device, can reduce the maintenance cost.

PVC pipe equipment has the function of mixing raw materials; The extruder ensures the stable extrusion of the product, plasticizes THE PVC mixture and pushes it to the head; The extrusion die head part is the closed part of pipe forming; Vacuum shaping tank, used for shaping and cooling pipes; The tractor part is used to automatically draw out the formed pipe from the head; Cutting machine part for automatic cutting; Flip frame, to achieve the flip action, to achieve the purpose of unloading.

PVC pipeline equipment has the function of the use of PVC resin powder as the main raw materials for the production of pipelines and other pipeline materials.

Fault repair of plastic pipe

In the production process of plastic pipe equipment, there will inevitably be some faults, such as: plastic pipe surface roughness is not smooth, should timely adjust the process temperature; When furrow marks appear on the outer surface of the plastic pipe, the outlet pressure of the sizing sleeve should be adjusted to balance the outlet requirements. If there are furrows on the inner surface of the plastic pipe, check whether there is water in the inner pipe to reduce the temperature inside the mold; If the jitter ring appears in the plastic pipe, the outlet pressure of the sizing sleeve should be adjusted to make the outlet even. No vacuum, check whether the inlet of vacuum pump is blocked; The inner wall thickness of the plastic pipe is not uniform, so the inner wall thickness of the mold should be adjusted. If the length of the cutting instrument is not accurate, check whether the sizing wheel is pressed, and find out, check and deal with it in time.

There are also common problems with plastic pipes: first, poor tensile strength and toughness, often manifested as brittleness, low elongation, easy to fracture; Second, the impact resistance is very poor, even 10 times the impact, completely broken. Thirdly, the softening temperature is low and thermal deformation is easy to occur, which reduces the impact resistance, tensile strength and toughness of the pipeline.

More attention and investment should be paid to the problems existing in the plastic pipe in the aspects of the selection of auxiliaries, the ratio of raw materials, production technology and production equipment, etc., which should not be treated lightly but seriously.
