Air jet loom to achieve energy saving methods

The shuttleless loom mainly includes a gripper loom, a water jet loom, an air jet loom, and a rapier loom. Among them, the unit energy consumption of the projectile weaving machine (calculated by weaving per square meter of cloth) is the lowest, followed by the water jet loom, and the jet and rapier weaving machine are the highest. Which kind of loom a company purchases can't just use energy consumption as its main indicator, but textile machinery factories must pay attention to energy-saving technology when launching new machines.

The high energy consumption of air jet looms is mainly due to the energy consumption of the nozzles. The air jet loom manufacturers have studied the nozzle holes of the auxiliary nozzles very early, and adopted the shapes of single holes, porous holes, inverted cone holes, etc. Many of them have been applied in practice, and the auxiliary nozzles of various aperture shapes are excellent. Various innovations in the nozzles (including the primary and secondary nozzles) and the trachea not only save energy but also improve the weft insertion quality.

With the wide application of electronic technology in the monitoring and monitoring of looms, various companies have successively introduced new technologies and new measures for energy saving. For example, the application of electromagnetic nozzles for air jet looms is one electromagnetic shield from the past 4 to 6 auxiliary nozzles. The valve is equipped with 1 solenoid valve to 2 auxiliary nozzles, and the ordered switch of the solenoid valve is controlled by the electric control box to achieve the purpose of airflow relay injection. According to reports, this new technology can save 10% to 15% of air consumption. Taking an air jet loom of 4750px width as an example, the air consumption of a jet looms is 0.5-0.6 cubic meters per minute, and 48 air jet looms are equipped with air compressors of nearly 40 cubic meters per minute. A 40 m3/min compressed air machine is equipped with a tens of kilowatts of electric motor. Generally, the 4750px air jet loom has 24 to 26 auxiliary nozzles. In the weft insertion channel, each auxiliary nozzle has a spacing of 70 to 80 mm. Since 4 to 6 auxiliary nozzles are equipped with one solenoid valve, that is, 4 to 6 auxiliary nozzle switches. Time is at the same time, which can not save gas consumption. Now there are two auxiliary nozzles of the air jet loom equipped with one solenoid valve, and only two auxiliary nozzles have the same switching time, which creates conditions for saving gas consumption. As the speed of the loom increases and the number of auxiliary sprays controlled by each solenoid valve decreases, the speed of the auxiliary nozzle is required to be accelerated. This technique cannot be promoted without a high-performance, high-speed solenoid valve.
