气液增压泵密封元件是液压系统中的液压附件，也是不可缺少的一部分。
The sealing element of the gas-liquid booster pump is not only the hydraulic accessory in the hydraulic system, but also an indispensable part.
密封装置要求
Sealing device requirements
1.在工作压力和一定的温度范围内，应具有良好的密封性能，并且随着压力的增加可以自动提高密封性能。
1. In the range of working pressure and certain temperature, it should have good sealing performance, and with the increase of pressure, it can automatically improve the sealing performance.
2.密封装置与运动部件之间的摩擦要小，摩擦系数要稳定。
2. The friction between the sealing device and the moving parts shall be small and the friction coefficient shall be stable.
3.耐腐蚀性强，不易老化，使用寿命长，耐磨性好，磨损后可进行一定程度的自动补偿。
3. Strong corrosion resistance, not easy to aging, long service life, good wear resistance, and automatic compensation to a certain extent after wear.
4.结构简单，使用维护方便，价格低廉
4. Simple structure, convenient use and maintenance, low price
密封装置的类型和特点
Types and characteristics of sealing devices
1.间隙密封:间隙密封是根据配合面之间的小间隙进行相对运动的密封，常用于柱塞、活塞或阀柱的配合副。
1. Clearance seal: clearance seal is a relatively moving seal based on the small clearance between mating surfaces, which is commonly used for the mating pairs of plunger, piston or valve string.
2. O形密封圈:O形密封圈一般由耐油橡胶制成，横截面为圆形，密封性能好。
2. O-ring: the O-ring is generally made of oil resistant rubber, with circular cross section and good sealing performance.
3.唇形密封圈:唇形密封圈按截面形状可分为y形、v形、u形和l形。
3. Lip seal ring: the lip seal ring can be divided into Y-shaped, V-shaped, U-shaped and L-shaped according to the section shape.
4.组合密封装置。在管道接头的密封中，常用的是WD弹性密封、O形环密封和硬密封。
4. Combined sealing device. In the sealing of pipe joints, WD elastic seal, O-ring seal and hard seal are commonly used.
