Microcomputer control system of high temperature and high pressure dyeing machine

Conventional instruments are commonly used in the process to control high temperature and high pressure dyeing machines. However, due to the low temperature control level of conventional instruments, the best dyeing quality cannot be maintained. Sometimes, the temperature and pressure in the high temperature and high pressure dyeing pot increase sharply, and the system is out of control and accidents such as spray top occur. To this end, we designed a microcomputer-controlled high-temperature and high-pressure dyeing machine. The system consists of a BCM-81 single-board computer as the host, and is equipped with ADC and DAC, drive and alarm circuits, etc., with detection, alarm, display, control, etc. Function. After adopting software technologies such as automatic error correction and digital filtering, the accuracy, anti-interference ability and reliability of the system are improved. The input signal of the system is taken from the temperature sensor and the pressure sensor. The temperature and pressure in the dyeing pot are transformed and amplified After. High-pressure dyeing machine microcomputer control system: The high-pressure dyeing machine microcomputer control system is a real-time control system. It can achieve rapid temperature rise and multi-level temperature control such as heating, constant temperature, and cooling at a variety of different rates; it can automatically change the process curve parameters according to the process flow and automatically cut into the pressure control loop. The system has the functions of display, recording, alarm, etc., through the console and operation panel for man-machine communication; the host and peripheral equipment adopt domestically made stereotyped products and modular structure. The successful development of this system provides a new way for the transformation of yarn dyeing equipment in the textile industry.
