Textile Machine VFD Variable Frequency Drive 3AC 0.75KW 380V~460V


working principle


The air jet loom is a shuttleless loom that uses a jet stream to pull the weft yarn across the shed.


The working principle is to use air as the weft insertion medium, and the compressed airflow generated by the jet is used to pull the frictional traction force of the weft yarn, and the weft yarn is taken through the shed, and the jet generated by the jet is used to achieve the purpose of weft insertion. This weft insertion method enables the loom to achieve high speed and high yield. Among several shuttleless looms, the air jet loom is the one with the highest speed. Due to the reasonable weft insertion method, the weft insertion rate is high, the operation is simple and safe, the variety adaptability is wide, the machine material consumption is low, and the efficiency is high. High speed and low noise have become one of the most promising new types of cloth machines.
