In the transformation and upgrading of "made in China 2025", improving efficiency and reducing energy consumption are one of the key indicators. In the traditional textile industry, the energy-saving effect can be significantly achieved by improving the process control scheme. Next, the frequency converter manufacturer aozhuo technology will take you to learn more!
Spinning frame is one of the common spinning equipment, and it is also the most energy consuming machinery and equipment in spinning production. In the textile process, the main function is to retract the wire feeding frame (feeding) and spindle (receiving) through different speeds to complete the coarse twisting (initial twisting) process of cotton yarn, glass fiber and various chemical fibers, and make the fiber have strength and elasticity through different twists.
In the large, medium and small yarn stages of doffing, there are obvious differences in the change demand of tension. According to the requirements of spinning frame equipment control, aozhuo technology has launched qd808 series textile special frequency converter, which can help the spinning frame complete better rough twisting process.
Qd808 series special frequency converter for textile can realize automatic stepless speed change and optimize spinning conditions, so as to maintain the tension stability at all stages of spinning as much as possible. In the stage of small yarn and large yarn, the response speed is reduced to reduce the breakage rate and poor hairiness; In the middle yarn stage with a length of about 80%, the speed is steadily increased. So as to accelerate the overall operation efficiency, high quality and high yield, reduce energy consumption and personnel labor intensity.
The application scheme adopts four qd808 series textile special frequency converters to control one permanent magnet motor and three induction motors respectively; The frequency converter controlling the permanent magnet motor is the main frequency converter, which is used to drive the spindle to rotate and supply DC power to the other three frequency converters at the same time. The other three frequency converters can complete the operation procedures of driving the twisting steel ring, spindle loading and unloading, and spindle transfer through controlling the induction motor.
In this scheme, the upper controller inputs the start signal and sends the analog current to the spindle frequency converter to control the spindle speed; The second group of analog current signals are sent to the ring frequency converter. The ring motor control mode adopts VF + position feedback to move the ring up and down and adjust the position of yarn winding on the spindle; The third group of analog current signals are sent to the wire feeder motor frequency converter to operate the wire feeder motor; The motor carrying the spindle drives the conveyor belt to send the wound spindle to the discharge port, and move the empty spindle to the winding position at the same time.
Qd808 series textile special frequency converter has small volume, stable control, supports a variety of driving modes, high conversion efficiency and effective energy saving; With high efficiency permanent magnet motor, the volume is smaller than that of induction motor, and the energy efficiency is superior.
Through combing and optimizing the spinning process, the application solution of aozhuoer textile special frequency converter in spinning frame shows excellent control ability and energy-saving effect. It is believed that this scheme can provide reliable support for many textile enterprises in optimizing process, saving energy and reducing consumption and improving competitiveness.
