液壓缸的結(jié)構(gòu)基本上可以分為缸體組件、活塞組件、密封裝置、緩沖裝置和排氣裝置五個(gè)部分。缸體組件和密封裝置構(gòu)成液壓缸的密封容積來(lái)承受液壓力，所以缸體組件要有足夠的強(qiáng)度、剛度和可靠的密封性。

1、升降機(jī)法蘭連接式，結(jié)構(gòu)簡(jiǎn)單，容易加工，也容易裝拆，但外形尺寸和質(zhì)量都較大，常用于鑄鐵制的缸筒上。
Speaking lifts lift manufacturers flanged, simple structure, easy to process, but also easy assembly and disassembly, but the dimensions and quality are larger, the commonly used cast-iron cylinder.

2、半環(huán)連接式，它的缸筒壁部因開(kāi)了環(huán)形槽而削弱了強(qiáng)度，為此有時(shí)要加厚缸壁，它容易加工和裝拆，質(zhì)量較輕，常用于無(wú)縫鋼管或鍛鋼制的缸筒上。
Lift manufacturers introduced a half loop-connected, its cylinder wall due to open the annular groove weakened strength, for sometimes thicker cylinder walls, its easy processing and assembly and disassembly, light quality, commonly used in seamless steel or wrought steel cylinder barrel.

3、升降平臺(tái)廠家談到螺紋連接式，它的缸筒端部結(jié)構(gòu)復(fù)雜，外徑加工時(shí)要求保證內(nèi)外徑同心，裝拆要使用專(zhuān)用工具，它的外形尺寸和質(zhì)量都較小，常用于無(wú)縫鋼管或鑄鋼制的缸筒上。
Speaking lift manufacturers threaded connection type, cylinder ends its complex structure and, where required to ensure that the outside diameter of the outer diameter of the inner concentric machining, assembly and disassembly use a special tool, its dimensions and quality are less commonly used in seamless steel or cast steel cylinder barrel.

4、升降平臺(tái)廠家介紹拉桿連接式，結(jié)構(gòu)的通用性大，容易加工和裝拆，但外形尺寸較大，且較重。
Lift manufacturers introduce rod connection type, universal structure of large, easy processing and assembly and disassembly, but the larger dimensions and heavier.
