Abstract:

In order to investigate compressed air jet loom so as to evaluate the cause of leakage and the effect of parameters, and the effect of parameters, compressed air leakage tests in the transport and use peocess were carried out, aiming at the air-jet loom weft insertion system of a weaving workshop, and it is found that the leakage mainly results from three sapects of pipe transport, connection accessories and use site equipment, and the leakage is caused by no timely replacement of aged and damaged parts in the use process. The data analysis shows that the leakage and energy consumptio increase with the increase of the pressure drop and the temperature change. Through the experiments, numerical and theoretical analyses, the influence mechanism of the comperssed air in the air jet loom is revealed. On this basis, the leakage was discussed and the repair was optimized. The test results show that it can effectively reduce or even eliminate the leakage through the regular management, maintenance and reair of the weft in sertion of air-jet loom.
