Product Features:TheY-shaped non-rigid oil seal isahigh-performance sealing component specificallydesigned for high-pressureapplications. Itscross-sectionischaracterized by the distinctive "Y" shape,featuring a double-lip open structure. The working lip and non-working lip are not of the same height,and the structural symmetry is high.It is the most pressure-resistant model among similaroil seals,withamaximum pressure resistance ofup to 3 2 { M P a } .The special double-lip open structure enables the pressure to directly act on the lip, achieving the effect of "the higher the pressure, the tighter the seal",featuring strong pressure resistance, long service life,and no risk of lip rolling.The structure is relatively complex and the cost is slightly higher. These oil sealsare mainly suitable for high-pressure main oil cylinders,heavy machinery (such as excavator boomoil cylinders),and various industrial equipment with high-pressure and heavy loads sealing scenarios, providing stable and reliable high-pressure protection in harsh conditions.

DPM五组合液压油缸活塞密封圈 DPMFIVE-PIECEPISTONSEALINGRING

DPM是由五部分组成，是一种双向作用的密封和导向元件，由1个橡胶圈，2个承托环和2个导向环组成。橡胶圈动态和静态时都能起到良好的密封作用，承托环可防止橡胶圈被挤入密封间隙，导向环的作用是使活塞在缸筒内导向并吸收径向力；橡胶圈在受压时会将承托环和导向环推向缸壁，因此即使组合封被磨损后仍能得到压力补充。

活塞组合封的突出特点是挡圈，导向环和密封件安装于一个沟槽，极大的节省安装空间。常用于一体式活塞和缸径较小的油缸，活塞上不需要安装其他密封件。主要用于运动速度较低，内泄漏量要求严格，活塞密封安装空间有限的油缸。如推土机，挖掘机，装载机，液压闸门和农业机械等。

TheDPMis composed of five parts and is a bidirectional sealingand guiding element.It consists of1rubber ring,2 supporting rings and 2guiding rings.The rubber ring can provide good sealingbothdynamicallyandstatically.The supporting rings can prevent the rubber ring from beingpushed into the sealing gap.The guiding rings' function is to guide the piston within the cylinderandabsorbradialforces.Whentherubber ringisunder pressure,it pushes the supporting ringand guidingring towards the cylinder wall. Therefore,even if the combined seal is worn out, pressure can still be replenished.

The prominent feature of the piston combined seal is that the retaining ring,guiding ring and sealing element are installed ina groove,which greatly saves installation space.Itis commonly used in integral pistonsandcylinders with a smaller diameter.Noothersealsneedto be installed on the piston.Itis mainlyused in hydraulic cylinders with low motion speed,strict requirements for internal leakage,and limited installation space for piston seals.Such as bulldozers,excavators, loaders,hydraulic gatesand agricultural machinery,etc.
