武汉星兴达液压气动设备有限公司为您提供油泵型号
造成密封面损坏的原因,可归纳为如下几种。密封面损坏的原因有人为损坏和天然损坏两种。人为损坏,是因为设计不周、制造不精、选材不当、安装不正、使用不好和维修不力等因素引起的。天然损坏,是阀门正常工作情况下的磨损,是介质对密封面不可避免的侵蚀和冲蚀等造成的损坏。机械损伤,阀门密封面在开闭过咱中会产生擦伤、碰伤、挤伤等损坏。两密封面之间,在高温高压的作用下发生原子相互渗透渗出,产生粘连现象。当两密封面相互移动时,粘连处轻易拉撕。
管子的失效可能是当外压达到一定值时,管壁的径向挠度随压缩应力的增加而急剧增大,直到管子被压瘪。(螺旋板换热器)波纹管是由光管管坯加工而成。有资料介绍,波纹管失稳失效部位位于波纹管本体两端的直管段。该波纹管长度L=495mm,直径(以光管计)D=25mm,壁厚n=.8mm,LC为临界长度。由于LC=1.17D(D/n)1/2=1.3.5mm,LLC,故为长圆筒。
