摘 要: | 为探究喷气织机中压缩空气泄漏情况,以便对泄漏原因及参数影响进行评估,在织布车间从喷气织机引纬系统入手,对输送及使用过程中的压缩空气进行泄漏检测。结果发现,泄漏主要来源于管路输送、连接附件以及使用点设备3 方面,原因主要为使用过程中零部件老化及破损而没有及时修复更换。数据分析表明,压缩空气在使用过程中泄漏量、能耗随压降及温度变化的增加而增大。通过实验、数值及理论分析相结合揭示了压缩空气在喷气织机中泄漏情况及压降、温度等因素的影响机制。以此为基础,对泄漏进行了探讨并提出了修复优化。结果表明,通过对喷气织机引纬专件定期管理维护、检修保养,可有效减少甚至消除泄漏,从而达到降耗要求。

Evaluation and optimization of compressed air leakage in air-jet loom |
| |
Abstract: | In order to investigate compressed air jetloom 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. |
