升降機廠家分析說密封件按工作條件和介質性質的不同，有不同的類型，大家應根據不同的用處選取不同結構型式和材料的機械密封。那么大家在選擇時應該注意哪些問題呢？
1、升降機廠家分析說根據密封腔體壓力，確定密封結構采用平衡型或非平衡型，單端面或雙端面等。
Lift manufacturers analysts say the seal chamber pressure according to the body to determine the sealing structure using balanced or unbalanced type, single face or double face and so on.
2、升降機廠家介紹根據工作速度，確定采用旋轉式或靜止式，流體動壓式或非接觸型。
Lift manufacturers introduced according to the working speed, determine the use of rotary or static, hydrodynamic or non-contact type.
3、升降機廠家建議根據溫度及流體性質，確定摩擦副和輔助密封材料，以及正確選擇潤滑、沖洗、保溫、冷卻等機械密封循環保護系統等。
Lift manufacturers recommendations based on temperature and fluid properties, determine friction and auxiliary sealing materials, as well as the correct choice of lubrication, washing, heat, cooling and other mechanical seal circulation protection system.
4、升降機廠家提醒根據安裝密封的有效空間，確定采用多彈簧或單彈簧或波形彈簧，內裝式或外裝式。
According to the available space elevator manufacturers install the seal remind determined using multiple springs or single spring or wave spring, built-in or externally mounted.
