升降机厂家分析说密封件按工作条件和介质性质的不同，有不同的类型，大家应根据不同的用处选取不同结构型式和材料的机械密封。那么大家在选择时应该注意哪些问题呢？
1、升降机厂家分析说根据密封腔体压力，确定密封结构采用平衡型或非平衡型，单端面或双端面等。
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、升降机厂家介绍根据工作速度，确定采用旋转式或静止式，流体动压式或非接触型。
Lift manufacturers introduced according to the working speed, determine the use of rotary or static, hydrodynamic or non-contact type.
3、升降机厂家建议根据温度及流体性质，确定摩擦副和辅助密封材料，以及正确选择润滑、冲洗、保温、冷却等机械密封循环保护系统等。
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、升降机厂家提醒根据安装密封的有效空间，确定采用多弹簧或单弹簧或波形弹簧，内装式或外装式。
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.
