The shaft auxiliary sealing ring 42 not only prevents the coupling member 413 from coming into contact with the fluid in the rotating device 200, but also protects the locking property and the strength from the erosion of the fluid, and can greatly improve the overall service life.
3.維修更換方便：續上述，由於該結合件413是由該套管部411內周面徑向穿置以結合該套管部411與該端蓋部412，因此，若套管部411要進行維修或更換作業時，在將該封蓋單元3與該轉動設備200相互分離後，僅 需拆卸該結合件413即可進行該套管部411與軸輔助密封圈42的維修與更換作業，因此，在維修更換上更為方便。3. The maintenance and replacement is convenient: the above-mentioned joint member 413 is radially penetrated by the inner circumferential surface of the sleeve portion 411 to join the sleeve portion 411 and the end cover portion 412. Therefore, if the sleeve portion 411 is to be When the maintenance or replacement work is performed, after the cover unit 3 and the rotating device 200 are separated from each other, only The fixing and replacement of the sleeve portion 411 and the shaft auxiliary sealing ring 42 can be performed by disassembling the coupling member 413, and therefore, it is more convenient to repair and replace.
參閱圖3，本發明軸封2的第二較佳實施例，大致是與該第一較佳實施例相似，不相同的地方在於：該軸套單元4還包括一介於該軸套41之套管部411與端蓋部412之間的第二軸套輔助密封圈45。該第二軸套輔助密封圈45位於該結合件413且靠大氣側處，主要阻擋由外固定環61及外轉動環62對磨面滲出的腐蝕性流體影響結合件413，同時也能提升該套管部411與端蓋部412之間的密封效果。Referring to FIG. 3, a second preferred embodiment of the shaft seal 2 of the present invention is substantially similar to the first preferred embodiment. The difference is that the sleeve unit 4 further includes a sleeve interposed between the sleeve 41. The second sleeve between the tube portion 411 and the end cap portion 412 assists the seal ring 45.
