The utility model relates to a centralized vacuum system for PVC plastic profile production line, belonging to the field of industrial production vacuum pumping. The application of screw vacuum pump in plastic profile. Due to the huge market demand and broad development prospects, plastic profile products have been developed rapidly in recent years in China. Due to the fierce market competition, all plastic machinery manufacturers consider a problem, how to improve the productivity and qualification rate of plastic profile products under the premise of ensuring product quality, and how to give full play to the maximum capacity of equipment so as to reduce the production success of products Ben.
Why do we choose dry screw vacuum pump for the centralized vacuum system of PVC plastic profile production line?
The vacuum pump of the vacuum station generating device is connected with the vacuum tank of the primary water gas separation device, the vacuum tank of the primary water gas separation device is connected with the negative pressure water tank of the secondary water gas separation device, the vacuum pump of the vacuum generating device is connected with the negative pressure water tank of the secondary water gas separation device, the negative pressure water tank of the water gas separation device is connected with the water bracket of the vacuum water bracket device, and the negative pressure water tank of the secondary water gas separation device is connected with the negative pressure water bracket of the vacuum water bracket device The pressure water tank is connected with the setting platform, the vacuum generating device and the secondary water gas separation device are installed inside the setting platform, and the vacuum water rack device is installed on the setting platform. The advantages are: novel design, simple structure, safe and convenient use, remarkable energy-saving effect, reduction of labor and material loss, reduction of labor intensity, improvement of production stability, improvement of clear pipeline operation on site, sound and light alarm function.
The melted and degassed plastic materials in the extruder are processed into continuous profiles on the alignment table. Generally, these profiles are made into pipes or various technical profiles for windows, cable pipes, medical pipes, etc. The plastic material is drawn into the mold. For the purpose of cooling and lubrication, water film is produced between the inner part of the die and the continuous workpiece, and is extracted continuously by the imported screw vacuum pump.
As a new type of vacuum pump with environmental protection concept, the development of screw vacuum pump is obvious to all. This kind of oil-free vacuum pump will not only bring benefits to the enterprise, but also more of a future development direction, and will inevitably be replaced by oil vacuum pump. Many users have put their eyes on this new product.
At first, most of the screw vacuum pump is used in semiconductor industry, but after continuous development and research, it has a wide range of applications, chemical industry, medicine, electronics, food and other fields are also the industries in which it plays its expertise. It is used in semiconductor processing to produce displays, chips and other components, in the chemical industry, vacuum distillation and other solvent recovery, to avoid water pollution, and in the food processing industry for packaging and concentration of some products. Even the German screw vacuum pump in the application of plastic profiles also get excellent results. Its application is not only in these industries, but also in the continuous development and update, its application ability can not be ignored.
