How The Energy Consumption Of Air-jet Looms Is High
Jun 12, 2017

  How the energy consumption of air-jet looms is high, mainly in the energy consumption of the nozzles. The air-jet loom manufacturing enterprises have long been on the nozzle of the auxiliary nozzle were studied, using a single hole, porous, inverted cone hole and other shapes, many have been applied in practice, a variety of aperture shape of the auxiliary nozzle have their own advantages. Various innovations in the nozzles (including the main and auxiliary nozzles) and the trachea not only save energy but also improve the weft insertion quality.

  With the electronic technology is widely used in the monitoring and monitoring of looms, enterprises have introduced new technologies and new measures of energy saving, such as air jet loom auxiliary nozzle solenoid valve application from the past 4 to 6 auxiliary nozzle configuration 1 electromagnetic The valve to the two auxiliary nozzle configuration of a solenoid valve, controlled by the electronic control box solenoid valve order switch, in order to achieve the purpose of air flow control jet. According to the introduction of this new technology alone can save air consumption by 10% to 15%. In the case of an air-jet loom of 190 cm reed, an air-jet loom is 0.5 to 0.6 m3 / min, 48 air-jet looms are equipped with an air compressor of nearly 40 m3 / min, and one 40 m3 / min Compressed air machine to configure a set of tens of kilowatts of the motor. Generally 190cm air-jet looms have 24 to 26 auxiliary nozzles, in the weft insertion channel each auxiliary nozzle spacing 70 ~ 80mm, because 4 to 6 auxiliary nozzle configuration 1 solenoid valve, that is 4 to 6 auxiliary nozzle switch Time is the same, so can not save gas consumption. Now there are two auxiliary nozzles equipped with one solenoid valve, only two auxiliary nozzle switching time is the same, which in order to save air consumption to create the conditions. With the increase of the speed of the loom and the decrease of the number of auxiliary nozzles controlled by each solenoid valve, it is required that the auxiliary nozzle speed should be accelerated and there is no high performance and high speed solenoid valve.

  Loom in addition to air weft energy consumption, the other institutions of energy consumption is also great, the most important is the beating mechanism. There are two kinds of beating mechanism: crank connecting rod mechanism and conjugate cam beating, the two institutions have their own advantages and disadvantages. 20 years of production practice comparison shows that: these two beating institutions are in line with production requirements. For individual heavy-duty fabrics, the use of conjugate cams has its outstanding advantages, while the crank-joist mechanism is slightly lacking in this respect. For the vast majority of products, the two institutions are exactly the same. From the quantitative point of view, air-jet looms use the crank link mechanism of the absolute majority. The rapier loom evolved from the crank connecting rod mechanism to the conjugate wheel beating mechanism. And the shuttle loom is not used conjugate cam beating mechanism can not.

  Followed by the opening agency. Regardless of the cam opening or multi-arm openings are large energy consumption of the body. But the same is the cam opening, the negative cam is slightly lower than the positive cam energy consumption. Two cam openings have their own advantages and disadvantages, the user should be based on the specific circumstances of their own purchase. Multi-arm opening energy consumption than the cam opening. Japan Toyota and Tsudakoma have launched a lifting rod 1 servo motor electronic arm, cancel the electromagnet, cam, energy consumption than the existing electronic arm of much lower, the adjustment is also very convenient.

  Speaking of air-jet looms can not fail to mention the air compressor. Now the domestic enterprises to use the air compressor is not ideal, the compressor efficiency is low, and because the vibration and noise are relatively large, the compressor to be installed in a certain distance from the air jet loom workshop, so the pipeline energy loss.
