O形密封圈適用于裝在升降平臺(tái)升降平臺(tái)上，在規(guī)定的溫度、壓力、以及不同的液體和氣體介質(zhì)中，于靜止或運(yùn)動(dòng)狀態(tài)下起密封作用，O型密封圈是液壓與氣壓傳動(dòng)系統(tǒng)中使用最廣泛的一種密封件。下面濟(jì)南天銳升降機(jī)械的有關(guān)專家就給大家詳細(xì)介紹一下液壓缸O型圈的特點(diǎn)。

1、O形圈密封性能優(yōu)良，工作壽命高，動(dòng)態(tài)壓力密封工作壽命比常規(guī)橡膠密封制品高5—10倍，最高可達(dá)數(shù)十倍，在某些條件下可與密封基體同壽命；O型圈高耐磨，密封面磨損后具有自動(dòng)彈性補(bǔ)償功能。
Lift manufacturers introduce O-ring sealing performance, working life high dynamic pressure seal 5-10 times working life than conventional rubber seal products, up to a few times, under certain conditions, with the seal matrix with life; O high wear-ring sealing surface elasticity worn with automatic compensation.

2、O型圈具有良好的自潤(rùn)滑性能，可作無(wú)油潤(rùn)滑密封，O型圈結(jié)構(gòu)簡(jiǎn)單，安裝方便。
O-ring analysis elevator manufacturers have good self-lubricating properties, can be used for non-lubricated seals, O-ring structure is simple and easy to install.

3、O型密封圈主要用于液壓缸靜密封和往復(fù)運(yùn)動(dòng)密封。用于旋轉(zhuǎn)運(yùn)動(dòng)密封時(shí)，僅限于低速回轉(zhuǎn)密封裝置。O型密封圈一般安裝在外圓或內(nèi)圓上截面為矩形的溝槽內(nèi)起密封作用。O型密封圈在耐油、酸堿、磨、化學(xué)侵蝕等環(huán)境依然起到良好密封、減震作用。
Speaking lift manufacturers O-ring is mainly used for static seals and hydraulic cylinder reciprocating seal. For rotational movement of the seal when limited to low-speed rotary sealing device. O-ring is usually installed on the outer or inner circle from the seal section is rectangular trench. O-ring seals still play a good shock absorption in oil, acid, wear, erosion and other environmental chemistry.
