多汽源高温差分汽缸泄漏原因分析

Analysis of Divulgence for High Temperature Difference Branch Cylinder in Much Steam Source

从某厂一分汽缸破裂泄漏情况入手,对裂纹原因进行分析研究,其原因由于两个汽源温差太大,受到压力波动影响,内部介质剧烈运动,筒体内部材料受到很大的温度应力,为典型的热疲劳破坏。

In accordance with the divulgence situation of a branch cylinder in a factory, investigation and analyzing the reason of engendering crackle, such reason is due to the fact that two steam source range of tempera-ture are very much great, and being subjected to the alternate pressure effect, the interior medium moving strongly, the body inside is subjected to very great temperature stress, it is the typical thermal fatigue damage.
