New technology and control method for ultra-low bath ratio high temperature and high pressure yarn dyeing machine Jul 09, 2018

The ultra-low bath is more advanced than the high temperature and high pressure yarn dyeing machine, and a new pulse flow process is also specially adopted. The time pulse generator is a computer that sends a pulse signal to the controller according to a random signal, and changes the frequency of the 16-pulse pulsation fluctuation frequency of the motor every minute. This frequency change is caused by fluctuations within the allowable range of the water level.

 

The controller of the ultra-low bath ratio high temperature and high pressure yarn dyeing machine adopts the ideal reference model, and the variable frequency motor controls the ultra-low bath ratio three-stage impeller pump, the output pulse shock wave, the ideal model and the output pulse flow are compared, and the adaptive water level monitoring is obtained. The water warning line gives the reference identification of the water level, and adjusts the speed of the variable frequency motor to reach the impact pulse flow of the dyeing process.

 

In fact, for the ultra-low bath ratio high temperature and high pressure yarn dyeing machine, the ideal reference model is the quality control law of the new dyeing process. According to the dyeing materials, cotton, man-made fiber, chemical fiber and other three different dyeing process rules are selected. Impact pulsation dyeing is carried out at an ultra-low bath ratio, the dye solution does not soak the spindle, and the amount of dye additive in the yarn dyeing machine is reduced.
