Plastic pipe equipment can also be called plastic pipe production line. Plastic pipeline equipment is an important part of chemical building materials, which is widely accepted by users for its excellent performance, health, environmental protection and low energy consumption.
Composition of plastic pipe equipment
The pipe production equipment has a control system, and then consists of an extruder, a mold, a setting cooling system, a tractor, a cutting device and a turnover frame. Each pipe production line has two screw extrusion equipment. The main extruder adopts power transmission sleeve and high-efficiency screw, and the other smaller extruder extrudes and scores. The failure of plastic pipe production line will lead to rough surface, internal vibration ring and no vacuum, so it can quickly eliminate the failure of plastic pipe production line and improve product quality.
Classification of plastic pipe equipment
Plastic pipe production includes pe pipe equipment and PVC pipe equipment. PE pipe equipment has special structure, high degree of automation, simple operation and stable and reliable continuous production. The pipeline produced by plastic pipe production line has moderate rigidity, good strength, good flexibility, creep resistance, environmental stress cracking performance and good thermal satisfaction performance, so it must be the first choice for urban natural gas pipelines and outdoor pipelines.
Structural design of plastic pipe
The head of PE pipe equipment adopts the most advanced basket head or spiral shunt pipe extrusion compound head design, which is convenient to adjust and uniform in material extrusion. The sizing sleeve adopts unique grooving technology and water ring cooling to ensure the forming accuracy of the pipe.
PE pipe production line, polyethylene high-efficiency screw, slotting machine barrel and strong water jacket cooling greatly improve the conveying capacity and ensure effective extrusion; Vertical structure of high torque reducer; DC drive motor. The basket compound die suitable for polyolefin processing not only ensures high extrusion stability and low melt temperature, but also can realize minimum pressure and bring the highest pipeline quality. High vacuum double-chamber sizing technology and spray cooling water tank can improve the output of pipeline and meet the needs of high-speed production. Crawler tractor has stable traction, each traction is driven by an independent AC servo motor, and digital controller controls the precision and speed adjustment of driving technology to achieve high synchronization. High-speed and accurate cutting machine design, horizontal cutting, and equipped with powerful chip suction device, will reduce maintenance work to a minimum.
PVC pipe equipment has the function of mixing raw materials; The extruder part ensures the stable extrusion of products, plasticizes the PVC mixture and pushes it to the die; The extrusion die part is the key part of tube forming; The vacuum shaping water tank is used for shaping and cooling the pipeline; The tractor is used to continuously and automatically pull the formed pipe from the machine head; The cutting machine carries out automatic cutting; The turnover frame realizes turnover action and achieves the purpose of discharging.
The function of PVC pipe equipment is to produce pipes and other pipes with PVC resin powder as the main raw material.
Failure maintenance of plastic pipe
Some failures will inevitably occur in the production process of plastic pipe equipment, such as: the outer surface of plastic pipe is rough and uneven, and the process temperature should be adjusted in time; Groove marks appear on the outer surface of the plastic pipe. Adjust the outlet pressure of the sizing sleeve to ensure a balanced water output. Groove marks appear on the inner surface of the pipe, check whether the inner pipe is flooded or not, and reduce the internal temperature of the mold; There is a shaking ring inside the pipeline, so adjust the outlet of the sizing sleeve to make it uniform; If there is no vacuum, check whether the water inlet of the vacuum pump is blocked; The wall thickness of the pipe is uneven, and the wall thickness is adjusted on the die; If the cutting length is not accurate, check whether the length measuring wheel is pressed down, etc. , must be found in time, check and deal with.
Plastic pipes also have common problems: first, the tensile strength and toughness are poor, often brittle, with low elongation and easy to break. Second, the impact resistance is poor, even 10 shocks are broken. Third, the softening temperature is low, and it is easy to deform when heated, which reduces the impact resistance, tensile strength and toughness of the pipe.
For the problem of plastic pipes, we should pay more attention to and invest in the selection of additives, raw material ratio, production technology and production equipment, and we should not take it lightly and deal with it seriously.
