Functions and advantages of the hydraulic pelletising screen changer

Hydraulic pelletizing screen changer can be used for mixing, masterbatch, recycling, extrusion, extruding profiles, manufacturing tubes, coating tubes and biaxial orientation. Hydraulic screen changer is an important part of the extrusion process, especially the production of plastic recycling and filler. The exchange system is generally composed of exchange device and power system, in which the exchange device also includes the body, sealing components, porous plate, filter, exchange device and so on.　　Role of hydraulic pelletizing screen changer.　　The hydraulic tool slides the flat plate through the housing and the polymer melt begins to flow through the next screen. After changing to the filter screen, the plate can be returned to the production position when the other screen needs to be cleaned, as the polymer melt flows through both screens and the other screen needs to be replaced, so there is no need to stop production.

Characteristics of Hydraulic Pelletizing Screen Changer It operates well under high temperature, and it operates well under high pressure of 25MPa-30MPa. Screen changer diameter is 30mm-250mm. high voltage, large filtration area, good abrasion resistance, adopts precision electric ruler control system, reliable and dependable hydraulic system. The double sealing system of copper sealing ring is water-cooled in the upper and lower layers of the screen-changing body. The material of the screen changer element is very important, generally use high quality alloy steel, after special heat treatment, so as to achieve high hardness, high wear-resistant effect, so as to ensure that the screen changer element is not deformed under high temperature and high pressure, so as to ensure that the screen changer sealing precision.　　Advantages of hydraulic pelletizing screen changer Screen switching time is not more than 2 seconds.　　Adopting advanced pressure adaptive sealing technology, the sealing element is driven by the pressure of the polymer in front of the screen, so that the product achieves bubble-free sealing effect.
