AI Technical Summary
Traditional high-pressure nitrogen supply systems for tire vulcanization are energy-intensive, have unstable pressure control, are complex, and occupy a large area, making it difficult to meet the needs of efficient and stable production.
The system adopts a direct supply mode of liquid nitrogen boosting and high-pressure vaporization, combined with feedforward control and pressure-flow cascade feedback control. By collecting the gas load signal of the vulcanizing machine in real time, calculating the feedforward compensation flow, and adjusting the flow with pressure feedback, the system achieves precise control of the liquid nitrogen pump, eliminating the gas compressor and optimizing the system structure.
It significantly reduces system energy consumption, improves pressure control accuracy and stability, ensures uniformity of tire vulcanization quality, simplifies system structure, and enhances equipment safety and reliability.
