gear pump rubber extruder

In the rubber industry extrusion production enterprises, the rubber viscosity is very high. The temperature is strictly controlled during production, usually only tens of degrees. If it is too high, it is easy to vulcanize. The barrel is connected to the cold water cycle, and it is cut directly after the training. Feeding into the extruder is forced to be transported to the die by shearing by the extruder. Due to manual feeding and uneven size of the strip, the pressure is very unstable, which directly affects the tolerance of the product, and the quality cannot be guaranteed. The batte rubber gear pump has an efficient self-cleaning function, a simple design, and an optimized fluid passage. The pulsation rate is lower under high pressure difference. Suitable for polybutadiene rubber, chloroprene rubber, EPDM, SBR, NBR, Tianre rubber and other processes.

rubber polymer melt pump is installed on the extruder, which can transfer the pressure building function of the extruder to the gear pump. The screw length-to-diameter ratio of the extruder can be shortened to 3-6, and the driving power is reduced; the extruder can work under low pressure, the backflow generated by the pressure flow is greatly reduced, and the extrusion temperature of the rubber compound is reduced to 60-80 ℃, not only can prevent the scorching of the rubber, but also provide the possibility to increase the screw speed and increase the output. Therefore, the gear pump extruder can process compounds with higher heat sensitivity under higher pressure. Under the conditions of low friction and low compound temperature, the pressure required for fine straining is formed. It can be used as a rubber strainer on the production line, and can also be used in the rubber mixing workshop to further process the rubber to improve the quality of the rubber. At the same time, it can also preheat the hard-to-plasticize rubber and be used for the extrusion of the blank. The reduction of extrusion pressure can reduce the axial pressure of the screw and prolong the life of the machine more than doubled.
