PVC equipment function
(1) Mixing of raw materials for PVC pipe production line: PVC stabilizers, plasticizers, antioxidants and other auxiliary materials are added to the high-speed mixer according to the proportions and processes, and the materials are heated to the set process through self-friction between the materials and the machine. The temperature is then reduced to 40-50ºC by the cold mixer; in this way, it can be added to the hopper of the extruder.
(2) Extruder part of PVC pipe production line: This machine is equipped with a quantitative feeding device, so that the extrusion volume can be matched with the feeding volume, and the product can be extruded stably. 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 small screw diameter in the metering section reduces the heat transfer area and the melt. The shear speed enables the melt to be extruded at a lower temperature. When the screw rotates in the barrel, it plasticizes the PVC mixture and pushes it to the machine head, so as to achieve compaction, melting, mixing and homogenization; and to achieve the purpose of exhaust and dehydration. The feeding device and the screw drive device adopt frequency conversion speed regulation, which can realize synchronous speed regulation
(3) The extrusion die head part of the PVC pipe production line: the PVC that is compacted, melted, mixed and homogenized, and the subsequent materials are pushed to the die head by the screw. The extrusion die head is a key part of the pipe forming.
(4) The vacuum shaping water tank of the PVC pipe production line is a mold with double cavities, which is used for shaping and cooling the pipes. The vacuum shaping water tank is equipped with a vacuum system and a water circulation system for shaping and cooling. The stainless steel box body, circulating water spray cooling, The vacuum shaping water tank is equipped with front and rear moving devices and manual devices for adjusting left and right and height.
(5) The tractor of the PVC pipe production line is used to continuously and automatically lead the cooled and hardened pipe from the machine head, with frequency conversion and speed regulation.
Precautions for use of threading pipe
| 1. |
can not without reason winding, this will not only cause dead wire, but also increase the input of electricity reform. |
| 2. |
Do not wear too much thread in a threading tube. After threading, you should drag it to see if it can be easily pulled. |
| 3. |
If the line has joints, it is necessary to leave the black box buckle panel at the joints, which is convenient for replacement and maintenance in the future. |
