溢流染色机焊接弯头及附属换热器壳体应力检测

Stress measurement of spillway dyejigger welding elbow and its attachwed heat exchanger shell

溢流染色机在纺织染整生产中应用广泛 ,其焊接弯头及附属热交换器结构特别 ,并承受一定的气液压力 .通过对某公司从意大利引进的这种焊接弯头及热交换器壳体进行设计压力和水压试验压力下的应力测定 ,应力实测结果与理论计算值相一致 ,对这种溢流染色机的安全运行及进一步监测具有实际意义 .

Spillway dyejigger has been widely used in dyeing operation of textile industry. The structures of its welding elbow and attached heat exchanger are special, and they bear a specified pressure of gas and liquid. The stress level measurement of the spillway dyejigger welding elbow and its attached heat exchanger shell which were imported from Italy was carried out under the design pressure and the hydraulic pressure level. The results of measurement agree well with the theoretical values, and it has practical significance for safety operation and further monitoring of this kind of dyejigger.
