在纺织行业中,设备品种多,结构复杂,但很多纺织机械都需要调速。在纺织机械中,织物的匀线速度调整,经历了纯机械的差动机构、液压马达调速、绕线电动机和直流电动机几种调速形式。前述的几种调速方法性能差、能耗大。直流调速性能最为完美,但由于直流电动机电刷维护等问题,使它故障率高、寿命低。变频调速器性能好,可采用高可靠性的交流异步电动机,是一种优秀的交流调速方法。目前它在纺织行业中得到迅速的推广与应用。 1.变频器在纺织设备中的应用目
In the textile industry, equipment variety, complex structure, but many textile machinery need speed. In textile machinery, uniform fabric speed adjustment, experienced a purely mechanical differential mechanism, hydraulic motor speed, winding motor and DC motor speed control of several forms. Several of the aforementioned speed control methods have poor performance and high energy consumption. DC speed performance is the most perfect, but due to DC motor brush maintenance and other issues, it is high failure rate, low life expectancy. Variable frequency drive performance, high reliability can be used AC induction motor, AC speed is an excellent method. At present, it has been rapidly promoted and applied in the textile industry. 1. Inverter applications in textile equipment purposes
