Abstract

The invention discloses a detection and quantitative analysis method for compressed air leakage of an air-jet loom. The method includes the steps that first, change of ultrasonic waves of an air course pipeline of the air-jet loom is detected, and whether leakage happens or not is determined; then an infrared thermal imaging technology is adopted for determining a leakage point by analyzing temperature distribution on the surface of a leakage position; and at last, the temperature difference of the compressed air leakage position in an air course of the detected system is subjected to contrastive analysis, the function temperature variation relation with the pressure and air course hole diameter can be obtained, and thus the leakage amount is obtained. The invention further discloses a leakage detection device. By the adoption of the method, the ultrasonic waves and the infrared technology are combined for use in compressed air detection leakage of the air-jet loom, the leakage position can be located quickly and accurately, quantitative analysis of leakage can be made, and the limitation caused when the ultrasonic waves and the infrared technology are used independently is overcome. By analyzing the relation between parameters, causes of the leakage can be known more clearly, and thus textile enterprises can conduct leakage repair or part replacement according to the own conditions and the investment payoff period.

Description

technical field [0001] The invention belongs to the technical field of industrial detection, and relates to a detection and quantitative analysis method for compressed air leakage of an air-jet loom, and also relates to a device for detecting the leakage of compressed air of an air-jet loom. Background technique [0002] With the development of the textile industry, more and more air-jet looms are used in large quantities. As a power source, compressed air plays an important role in pneumatic pressurization, pneumatic conveying and pneumatic weft insertion. The air compression system provides compressed air at a certain pressure for the air-jet loom, including air compressors, post-processing equipment, air supply pipe network and ventilation and cooling facilities, and is the power source of textile enterprises. [0003] The weft insertion of the air-jet loom uses compressed air as a carrier, and uses the high-speed airflow generated when the compressed air is released thr...
