moment, automation, intelligent textile equipment to ease the pressure on human resources costs, improve product quality, increasing prominence, it has also been widespread concern in the textile enterprise users. But industry experts generally believe that, in the search for automated textile equipment, high-speed, high-volume, while more attention should be saving this problem.

focus on energy efficiency at the right time

At the recent Twelfth Asian Textile Conference and 2013 annual meeting of Chinas textile and academic, RWTH Aachen, Germany (RWTH Aachen) Textile Institute of Technology professor Thomas Gries been titled "textile production in the energy Efficiency - Best Practices with advanced level beyond, "the theme of the report. In his report, statement, in the textile equipment design experience with the use of the producer should be the focus on energy efficiency.

Thomas Gries that, for the textile industry, the decisive factor is the cost of energy, so energy efficiency is a textile equipment sales experience in one of the most important issues. He described the development of the textile industry development trend of energy efficiency, including energy-efficient drive systems, energy recovery with advanced process control technology, and interpret some advanced textile equipment cases of application of these techniques. He believes that improving energy efficiency is not just for cost considerations, is related to the future development of important issues.

senior engineer of Shanghai Textile Engineering Society Cang Hai explained, the moment Jiangsu Province have been some foreign businessmen require export enterprises labeled with energy consumption per unit of production of the phenomenon. When that require more time, the domestic textile enterprises re-tried on such a request, it looks a little caught off guard.

When it comes to energy issues loom, Hai Cang believes that air-jet looms the biggest problem is how to reduce energy consumption. Production of similar products, the use of the use of air-jet looms rapier than 30% of energy savings. Jet looms about 70% of the energy consumption is used in the gas supply system work. Gas supply system in the present mode of operation, air jet loom very difficult to reduce energy consumption.

automation reduces energy yields

need for additional control system automation equipment, configuration, an increasing number of motor, inverter, which will increase energy consumption; thickness of the joint, fine network associated transmission system have power-driven, will increase the energy consumption; equipment production Ascension requires motor has a higher power, but will increase energy consumption. However, China Textile Machinery Association, vice chairman Zhu Xianmin that the high degree of automation equipment, the surface will bring about an increase in energy consumption, but the average yield on the Units may be no increase in energy consumption.

Wuhan Textile University Textile fibers and products MOE Key Laboratory also conducted an on traditional textile equipment, textile equipment with new automated comparison of energy consumption survey proved that automation of textile equipment in energy savings perspective advantage.

researchers Mae Textile Co., Ltd. in Hubei were compared. Lee has two 30,000 U.S. textile production lines, one is the K45 compact spinning production lines, one is the traditional carded cotton production lines, the production of 100 British branch with 45 British branch of cotton yarn. Researchers two pure cotton yarn energy converted into 21 English pure cotton yarn consumption in kilograms. K45 compact spinning yarn production line kilograms energy consumption of 0.8499 kilowatts, the traditional carded cotton yarn production kg energy consumption of 1.112 kilowatts. Therefore, researchers believe that the use of new automated textile equipment, although it will increase energy consumption, but will also enhance production, improve yarn quality. By the way the yarn converted into standard comparison, the new automated textile equipment still has advantages in energy perspective.

In addition to comparing the energy consumption of the entire production line, the researchers also on a single device with a continuous energy consumption compared to the production system. Researchers Zhangkuai Juan explained, the modern carding system with the traditional opening and cleaning - carding production line, the formers smaller footprint, lower air consumption with energy consumption. Carding the three different models of energy consumption comparison test, the modern production carding machine energy consumption per kg of sliver 82.6 kwh, respectively, while the traditional carding 102.0 kwh, 98.6 kilowatts · time. Because the speed has improved, so modern technology more energy efficient.

intelligent energy-saving way out

saving for the future direction of textile equipment problems, Zhu Xianmin that is the way to keep the intelligent development. He believes that intelligent energy-saving equipment is also seeking a purpose. Out as, the moment although some devices do not work, but still want to continue running the state, which is to prevent the device can not operate normally after boot, in which experience alone energy consumption. If the device has completed a higher level of intelligence, it can not completely stopped running, wait until you need to preheat operation in advance, it is possible to save energy.

as energy-hungry air-jet looms, present mainly adopted for weft experienced dynamic, precise control of the way, with the auxiliary main nozzle nozzle control solenoid valve opening and closing timing and duration of conduction jet, thus achieve energy saving goals. Moment weft experienced dynamic control energy technologies: experiences on the implementation of closed-loop control of the weft, weft improve accuracy; adoption of low pressure weft insertion technology, so soft with low tension weft weft, in order to reduce consumption; improved nozzle structure, improve air concentration, reduced air consumption; adoption of multiple air bag, respectively, to the main and auxiliary nozzle gas; adoption is not the same pressure compressed air storage auxiliary air bag, for use in large differences in the weft weaving, so that each weft main adjustable nozzle pressure, auxiliary pressure nozzles can be automatically switched Sec; choose high-sensitivity small cavity solenoid valve, reducing gas, optimize the solenoid valve control nozzles and other measures to achieve energy saving goals.

Hai Cang instructions, Sulzer year before the launch of A9500-jet loom weft entrance can detect the weft flight speed, and when the latitude of the auxiliary nozzle opening and closing time to make adjustments, can save 25% of gas consumption . Moment, Nissan with homemade loom also difficult to do this, mostly in the second latitude to make adjustments. This technique requires rapid detection testing organizations loom, rapid reaction control system, equipment for rapid processing. Completed in the three angles greater automation and intelligence, we can make further reduce the energy consumption of air-jet looms.

in Shaoxing Sheng Pu Electronic Technology Co., Ltd. S3C2416-based intelligent energy-saving control system of the twister, the traditional Twister induction motor using permanent magnet AC synchronous servo motors are replaced, to achieve a certain energy saving effect. Through control of the controller, the motor starts with the impact on the grid when braking decrease driver also allows a constant load on the motor, reduce energy consumption.
