Air Jet Loom
Abstract
Air Jet Loom Solution
Air jet looms are core equipment in modern textile industry and used in the fields of clothing, home textile and industrial textile. In the early days, it monopolized by Japanese companies such as Toyota and Toda Kikukawa, with high prices and maintenance relying on the original factory. In recent years, domestic brands such as Shandong Rifa and Zhejiang Titan have risen rapidly,occupying 60%-80% of the domestic market share with import prices ranging from 60% to 80% and localized services.
The traditional air jet loom operation mode has the problem of "high maintenance + low efficiency" : different fabrics (plain weave/twill weave/jacquard) require speed of 300-1200 RPM, and the speed need adjusted by replacing different diameter pulleys. Each loom needs to change the pulley more than 10 times per month, each time taking 1-2 hours, which seriously drags down the efficiency. Data from 20 domestic looms of a certain companies in East China revealed the shortcomings of this solution:
Low production efficiency: Each pulley replacement requires a 1-2 hour downtime, and the average monthly downtime exceeds 100 hours, seriously affecting production capacity;
High equipment wear and tear:Purchasing of pulleys, manual wheel replacement and equipment wear and tear result inpersistently high maintenance cost.
Poor process flexibility: Fixed rotational speed is difficult to match the processes of different fabrics (such as plain weave and jacquard), which affects product quality. It is unable to meet the market demand for "small batches and multiple batches".
Solution
In response to the above issues, SAVCH has developed the S3100A series of special ultra-start inverter for weaving machine. It is a special inverter designed for the application of supporting and upgrading jet looms in the weaving industry. It is easy to install and use, meeting the ultra-start requirements of jet looms. It features continuous adjustable operating speed and no motor start shock, significantly extending the service life of the motor and equipment.
Product Highlights
Air jet loom inverter can achieve ultra starting, precisely controlling the start-up, speed and torque, reducing shock and achieving energy saving and high efficiency. When changing the fabric type, there is no need to replace the pulley, saving the time for pulley replacement.
Super start inverter solution:
Super start: Maximum starting torque is 200%, achieving a greater warping torque compared to the normal frequency start up, effectively addressing the problem of machine stoppage.
Energy saving: High power factor, reduction of reactive power loss, increasing active power in the power grid, and comprehensive power saving rate up to 15% at 80% rated load.
Speed adjustment: For complex fabrics, different weft colors or weft densities can be set, the loom speed can be changed through simple parameter settings to achieve rapid switching of production processes.
Stable speed: The main circuit uses large-capacity, high ripple capacitors, supplemented by software AVR control, effectively reducing the impact of grid fluctuations on the loom speed.
