PVC STEEL WIRE HOSE Equipment Anatomy Analysis of Plastic Granulator

Plastic granulator control system includes heating system, cooling system and process parameters measurement system, mainly by the electrical, instrumentation and implementing agencies. Below we will plastic granulator / system is divided into six areas for anatomical analysis: ① screw speed control: Screw speed regulation and stability of the host drive is one of the important process requirements. Screw speed directly determines the amount of plastic and extrusion speed, the normal production always want to maximize the maximum speed and achieve high output, the extruder screw speed required from starting to the required working speed, the available speed range to be large . And the stability of the speed of the high demand, because the speed fluctuations will lead to fluctuations in the amount of extrusion, extrusion quality, so no change in the traction line speed, it will result in changes in cable diameter. Similarly, such as traction device line speed fluctuations can also lead to changes in the cable diameter, screw and traction line speed can be reflected by the corresponding instrument on the console, extrusion should be closely observed to ensure high quality and yield.
② pressure control of the extruder: In order to reflect the head of the extrusion situation, the need to detect the extrusion head pressure, as the domestic extruder without head pressure sensor, the screw extrusion is generally measured after the thrust substitution Head pressure measurement, screw load table can correctly reflect the size of the extrusion pressure. The fluctuation of extrusion pressure is also one of the important factors causing the unstable quality of extrusion. The fluctuation of extrusion pressure is closely related to the extrusion temperature, the use of cooling device, the duration of continuous operation and other factors. When anomalies occur, the rapid exclusion can be ruled out and the production shut down must be reorganized. This not only avoids the increase of wastes, but also prevents the accident from occurring. By testing the pressure gauge readings, you can know the plastic pressure state in the extrusion, the general take the thrust limit alarm control.
