The AC frequency conversion technology is better applied to the control of textile machinery. The speed range is within the range of 100: 1. Including card opener, card, sliver, comber, draw frame, roving frame, spinning frame and Luo Jian machine. This machine has high control precision, stable performance and low failure rate. The highest speed can reach the standard of 1500r / min, which realizes new technologies such as man-machine dialogue and automatic positioning of parking wings.
The following highlights the roving frame sizing machine. 4 Prospects for the application of frequency converters in textile The process of internationalization of China's textile industry is accelerating. (2) Adopt speed sensorless vector control inverter, such as using V2 inverter of Tai'an Company without PG card. It has excellent low speed characteristics. It is suitable for slitting warping machines, sizing machines, heat setting machines, and chemical fiber filament spinning equipment with high speed regulation and constant tension and constant line speed. Makes the spun roll shape good. 3. In order to narrow the gap, we should continue to improve the level of mechatronics of textile machinery. Actively promote intelligent technology and fieldbus technology to achieve network control.. It also has good acceleration and deceleration characteristics, torque characteristics, and current limiting characteristics.
The air compressor energy-saving air jet loom Manufacturers system centrally controls the air compressor, and performs gas prediction based on historical operating data. Check the gas production efficiency of the air compressor. It introduced the international advanced spinning production systems of Rieter and Neumag in Germany, as well as the twisting and heating of German 'Sura', 'Su Sheng' and German SUPERBA Setting equipment, long-term supply of high-quality polypropylene BCF single-color, tri-color bulked yarn, network yarn, twisted yarn and twisted set yarn, nylon carpet yarn The object of this renovation is the compressed air system of the entire plant of the enterprise. Compressed air transmission link: There are bottlenecks and large pressure losses in the transmission network of the pipeline; there is no partial pressure supply to the pipeline network
The whole machine is controlled by industrial computer. Speed regulation accuracy can reach 0.1 Characteristics of AC frequency conversion speed regulation 1.1 FA491 high-speed roving frame This is a new type of roving frame developed in China in recent years. It has good process adaptability and reduces head breaks. However, there is still a big gap compared with the international advanced level. 3
