升降平臺(tái)作業(yè)過(guò)程中，密封件發(fā)揮著重要的作用。密封件是防止流體或固體微粒從相鄰結(jié)合面間泄漏以及防止外界雜質(zhì)如灰塵與水分等侵入機(jī)器設(shè)備內(nèi)部的零部件的材料或零件。那么如何防止升降平臺(tái)密封件的磨損呢？

通過(guò)實(shí)踐我們發(fā)現(xiàn)，只有在升降平臺(tái)密封圈表層形成保護(hù)層，使用時(shí)，密封圈與液壓油隔離開(kāi)來(lái)。使分子進(jìn)入材料的速度減慢，就會(huì)相應(yīng)地延長(zhǎng)了密封件的使用壽命。如果不想密封件外面保護(hù)層丟失，就必須在原材料的基礎(chǔ)上添加幾十種添加劑，使添加劑融合到聚氨酯分子之內(nèi)。隨著密封件使用時(shí)間的延長(zhǎng)，添加劑就會(huì)從聚氨酯分子內(nèi)慢慢的滲透到表層，在表層長(zhǎng)期形成保護(hù)層，這樣就解決了聚氨酯材料的老化。
Through practice, we found that only in the lift platform surface to form a protective layer seals, when used, seals and hydraulic oil to isolate. Slowing down the speed of the molecule into the material, will extend the life of the corresponding seal. If you do not want to seal the outside of the protective layer is missing, you must add dozens of additives on the basis of raw materials,so that the additive incorporated into the polyurethane molecules. With the extension of the seal use of time, the additive will slowly infiltrate from the polyurethane molecule to the surface,

forming a protective layer on the surface of the long-term. This would solve the aging of polyurethane materials.
 
密封件雖小，但是它在升降機(jī)中的起的最用很大。各種密封其性能影響因素是不同的，如機(jī)械密封（填料密封等）影響因素有溫度，介質(zhì)、磨損、所承受壓力等。按不同的用途，密封件按作用分類(lèi)分為軸用密封、孔用密封、防塵密封、導(dǎo)向環(huán)、固定密封、回轉(zhuǎn)密封；按材料分類(lèi)分為橡膠、聚氨酯、工程塑料等。
Seals are small, but it lifts the most played with great. Sealing performance of various different factors, such as mechanical seals (packing etc.) factors are temperature, medium, wear, the pressures and the like. According to different purposes, classified according to the role the seal into the shaft seal, hole sealed, dust-proof seals, guide rings, fixed seals, rotary seals;according to material classification into rubber, polyurethanes, engineering plastics.
