Process conditions and power control of high temperature high pressure liquid dyeing machine
Feb 08, 2019

The high temperature high pressure liquid dyeing machine circulates in a closed pressure vessel during the operation under the process of 100 ° C, and the air is trapped in the air, which is actually a steam. The mixture with air is denser than pure air and increases with increasing temperature. Therefore, the working load of the fan increases with the increase of the temperature, that is, the operating current of the fan motor increases and the power increases. Under this condition, the viscosity of the air is increased, the viscous force of the traction fabric is increased, and the relative sliding speed with the fabric is reduced, so that the circulation speed of the fabric is increased.

There are two phenomena in the process conditions of high temperature high pressure liquid dyeing machine
1. First, the power of the fan rises and the power consumption increases.
2. The fabric circulation speed is increased, which increases the fabric tension between the cloth roll and the air flow nozzle. In theory, the cycle time of the fabric is shortened, but in reality the fabric is stretched long, and the cycle time of some fabrics may not change much. Although these two phenomena have no effect on the levelness of the fabric, they have a great influence on the power consumption of the fan, the width of the fabric, and the longitudinal crease.
The fan motor of the high temperature and high pressure jet dyeing machine adopts constant power control, and the control process of changing the frequency with the load change is set by the computer program, so that the fan motor always works within the set working range, keeping the set power constant. . In this way, the influence on the running state of the fabric can be reduced, the quality of the fabric can be prevented from being excessively generated, and the power consumption can be saved. After production and application testing, the two tubes are dyed by disperse dyes (high temperature 130 °C), and the fan is controlled by constant power, which can save 3 to 4 kWh in one hour.
