What are the equipment classification and advantages of HDPE double-wall corrugated pipe production line?What are the equipment classification and advantages of HDPE double-wall corrugated pipe production line?
1. Classification of double-wall corrugated pipe production line equipment
1. According to the material produced: it can be divided into three categories: HDPE, PP, PVC, etc.
2. According to the structure and shape of the equipment: it can be divided into three types: horizontal, vertical and shuttle
3. According to the host configuration: can be divided into single screw host, conical twin screw host
2. Equipment introduction:
Double-wall corrugated pipe has the advantages of small specific gravity, low cost, high external pressure resistance, high strength, good resistance to mechanical vibration and freezing performance and long service life. Favor. Its production technology matured in the early 1990s. At present, many fields in developed countries have been widely used in large-scale agricultural water delivery, water supply and tap water, drainage, sewage and exhaust in various fields. In order to fill the gap of domestic large-diameter double-wall corrugated pipes, our company has developed high-density polyethylene (HDPE) large-diameter double-wall corrugated pipe equipment based on extensive research on technology and market. The product has a unique structure and has excellent physical and chemical properties and economic capabilities. Mainly reflected in the following aspects:
1. The output can be increased by ≥15% compared with similar domestic models.
2. It saves the time for changing the mold, which is 1 / 4-1 / 5 of the original time for changing the mold.
3. After the redesign of the mold, the ring rigidity of the pipe is improved, and the weight per unit meter is reduced by 4%.
4. The single and dual machines are used separately to save power consumption and reduce costs.
5. By increasing the traction machine, the pipe ring rigidity is improved to ensure the appearance quality of the pipe.
6. Transformation of the original cooling system improves the cooling effect, thereby ensuring the increase of output.
7. The size of the mold is designed according to international standards (according to European standards).
3. Equipment features:
The bellows production line adopts the internal positive and external negative forming principles, and the core components are composed of Siemens PLC plus expansion module, and MP277 computer screen. The speed of the two hosts can be adjusted, and the PLC can realize the setting, storage, correction, alarm, etc. of the working conditions such as the oil temperature of the gearbox, the speed of the host, the melt pressure, the melt temperature, the temperature of the barrel, the mold temperature, the molding speed Monitoring, display and other functions.
The production line mainly includes automatic feeding and drying system, 2 high-efficiency single-screw extruders (PVC twin-wall corrugated pipe production line our company uses conical twin-screw extruder), molding die, molding machine, spray cooling water tank, automatic turning Material rack, freezer and chiller etc.
