Batch pre-expander NKL-PSJ160

(1) Steam System: Adopts a steam pressure regulating valve and PID (proportional steam valve) system to control steam pressure and flow, achieving precise heating and controlling expansion density.

(2) Feeding System: Uses a weighing system, setting the feed weight on the HMI for automatic EPS material feeding, improving production efficiency.

(3) Compressed Air Control System: A high-precision filtering and decompression device is adopted. Proportional control of the air mixture flow adopts a proportional positioner to achieve precise analog control.

(4) Material Level Control: Adopts a dual vibration level sensor to detect EPS and precisely control EPS density, reducing density tolerance.

(5) Electrical Control System: Japan Mitsubishi PLC, France Schneider touch screen main control system, equipped with Schneider industrial control electrical components.

(6) Korean vibration sensor is adopted to achieve foaming material level control. Enter the desired density and the system will automatically calculate the amount of raw material input.

(7) Foam density weighing and feedback system: The foam density weighing and feedback system can accurately measure and display the density of each product in the mold.

At the same time, the system calculates and compares the deviation from the density targets and corrects and compensates for the input to achieve density control accuracy.
