Qingdao Jiawei company developed vertical and horizontal HDPE/PVC large diameter double-wall corrugated pipe production line, its products are widely used in electric wires, cables, street lamps and cables, communication cable pipe, urban drainage, agriculture and animal husbandry drainage, well with well-wall pipe, exhaust, ventilation and other purposes.
Performance and advantages: JWSBL vertical and JWSBW horizontal series HDPE/PVC double-wall corrugated pipe computerized extrusion line is professionally designed and manufactured with high output, stable extrusion and high automation.
Equipment features:
1, the extruder can be specially designed according to the user's raw materials, HDPE using a new type of high-efficiency single-screw extruder, PVC using a large-scale flat double or cone double extruder.
2, using KRSJ series PE high-efficiency single-screw extruder, the inner and outer corrugated pipes are fed by the extruder independently, which can realize the production of pipes with different raw materials and colors of the inner and outer layers, and ensure high-speed and high-efficiency extrusion. Enhanced market competitiveness.
3, the PE double-wall corrugated pipe production line can be slightly modified and increase the corresponding auxiliary machinery to produce steel skeleton winding hollow corrugated pipe. Replacement of extruder and related parts can produce PVC reinforced pipe.
4. Adopting super-cooling cooling system. Discharging speed is 15% higher than that of domestic models. The advanced programmable lubrication system minimizes the wear and tear of the molding module, which greatly extends the service life and ensures the running precision, guaranteeing the quality and stability of the bipyramidal corrugated pipe extrusion.
5 In addition to the advanced online double-wall flaring function, it can also realize off-line double-wall flaring, and arbitrarily set the length of the pipe. So that the thickness of the flared mouth to meet and exceed the requirements of national standards; completely solve the pipe creep, socket seal leakage drawbacks.
6. Single extruder and double extruder can be linked, can also be single. Realize the production of two-color, two-bit corrugated pipe.
7. Comprehensively optimized design of the wave structure, unique corrugated design, can be compared with similar models in the country to save 4% of the material, to achieve a perfect combination of high ring stiffness and low meter weight.
8. The special structure of the composite touch head makes the wall thickness of inner and outer layers even and the molding stable; and it can realize the stepless adjustment of the wall thickness. The corrugated molding module made of special alloy material has high precision and strength and excellent heat dissipation effect; it improves the working efficiency.
9. Unique mold changing technology saves the time of mold changing and improves the working efficiency.
10. Applying high precision positioning system, the module position can be determined arbitrarily
11. With remote communication function, it can realize remote diagnosis and troubleshooting.
Molding machine and mold: High precision of molding machine and head, good interchangeability of modules, two cooling modes of modules: water-cooled and air-cooled, on-line flaring can be realized to ensure the performance indexes of molded tubes, the circular double knife cutting machine has excellent cutting precision, the whole production line adopts the Siemens man-machine interface control system, which has a high degree of self-control function.
