在將旋轉接頭安裝固定支撐前，先應該了解旋轉接頭的內部結構，以做為采取何種方式的依據(jù)。

Before the rotary joint is installed on the equipment, the inner structure hereof must be learned for installation basis.

S系列旋轉接頭是球面密封結構，自支撐、外部補償設計。依靠彈簧推動殼體沿軸向向后移動起補償密封磨損的作用，完成內部介質與外界空氣的密封隔離。因此需要合理的安裝方式及定期的維護保養(yǎng)確保產(chǎn)品在設備中的使用.

S series rotary joint uses the spherical sealing structure. It is a self-supporting type with sealing compensation design. The sealing function is realized by the spring force on the body to move reversely, wherein the working media is sealed and isolated from the atmosphere effectively. Therefore, reasonable installation and periodical maintenance are necessary for the successful performance of the rotary joint.

如圖所示使用無油石墨軸承結構的旋轉接頭，使能在中心點上運轉。

As shown in the sectional drawing, the rotary joint uses two carbon guides for self supporting and axial concentricity, with maximal guide separation.

當石墨密封環(huán)磨損時，由于彈簧力及介質壓力的作用下，旋轉接頭的殼體會往后面移動，使密封面得到有效的補償。

During abrasion, under the spring force and the media pressure, the rotary joint will move reversely to make the sealing surface compensated effectively.

備注：

Remarks:
SN（020-065）與SC（020-065）除密封面有正反之分，內部補償機構結構相同  
SN(020-065) amd SC(020-065) have the same compensation structures, despite of different spherical sealing design (SN uses concave sealing design, while SC uses convex sealing design).
SN080/SC090/SC100除密封面有正反之分，內部補償機構結構相同
SN080/SC090/SC100 have the same compensation structures, despite of different spherical sealing design (SN uses concave sealing design, while SC uses convex sealing design).
SC(125-200)內部補償機構結構相同
SC(125-200) have the same compensation structures.
