普寧氣缸活塞桿-氣缸活塞桿價格-無錫精恒液壓(多圖)：

1、液壓系統存在高溫現象，在工作中活塞桿在(zai)高溫(wen)狀態下（特別是在(zai)寒冷季節）頻繁(fan)與低(di)溫(wen)環境接觸（溫(wen)度瞬間驟(zou)降）；

2、在保養周期(qi)時更換了非該品牌挖掘機液壓油，這個現象一(yi)般(ban)在剛換完油品幾天時間之內就會出(chu)現活塞桿(gan)變色。原因是液壓油里面有(you)一(yi)種極壓抗磨添加劑(ji)的品質和性能不同

3、活塞桿電鍍過程中(zhong)(zhong)因(yin)溫度控制不均勻導致在后期的(de)(de)工作中(zhong)(zhong)電鍍層表面出現龜裂，用高倍數放(fang)大鏡觀(guan)察活塞桿表面可以看(kan)到不規則細小裂紋。一般是液壓油(you)溫太高所致，且此現象多發(fa)生在使用較(jiao)多的(de)(de)鏟斗油(you)缸的(de)(de)前半部分(fen)。建(jian)議對散(san)熱器部分(fen)的(de)(de)灰土經常清洗，保證散(san)熱效果(guo)

問題：活(huo)塞(sai)密封(feng)與活(huo)塞(sai)桿密封(feng)的區別在哪兒？

答(da)：活(huo)(huo)塞(sai)密封(feng)(feng)，它是(shi)指(zhi)缸體與活(huo)(huo)塞(sai)之(zhi)間(jian)的密封(feng)(feng)，其密封(feng)(feng)槽(cao)一般在(zai)開(kai)(kai)在(zai)活(huo)(huo)塞(sai)上(shang)的。而(er)活(huo)(huo)塞(sai)桿密封(feng)(feng)，則是(shi)指(zhi)活(huo)(huo)塞(sai)桿與缸蓋之(zhi)間(jian)的密封(feng)(feng)，密封(feng)(feng)槽(cao)是(shi)開(kai)(kai)在(zai)孔上(shang)的。

鍍鉻棒活(huo)塞(sai)桿，它是用(yong)來支持(chi)活(huo)塞(sai)做功(gong)的一(yi)種連接部件，不(bu)過(guo)其在使用(yong)過(guo)程中(zhong)容易出現(xian)外泄現(xian)象。那么，造(zao)成該問題(ti)的原(yuan)因有哪(na)些呢？下(xia)面小編就來具體分析一(yi)下(xia)。

使得(de)鍍鉻棒活(huo)塞桿出現外泄(xie)現象，其原因主要有兩個(ge)，分別為密封(feng)圈失(shi)效，以及油液的污染(ran)，下(xia)面就(jiu)具體(ti)來講(jiang)解其中一個(ge)，為密封(feng)圈失(shi)效。

使得密封圈失(shi)效，一般來講，其具體(ti)原(yuan)因(yin)有：

原因一(yi)：防(fang)塵(chen)(chen)圈(quan)(quan)的(de)防(fang)塵(chen)(chen)效(xiao)果差，比(bi)如選型(xing)不合理等，因為現在對防(fang)塵(chen)(chen)圈(quan)(quan)的(de)要求是要能夠(gou)抗污(wu)染(ran)和抗高溫，而且這兩方面(mian)性能要好。但是一(yi)旦(dan)出(chu)現偏差，就會使防(fang)塵(chen)(chen)圈(quan)(quan)失去防(fang)塵(chen)(chen)功能，從而讓污(wu)物(wu)進(jin)入，使得密封失效(xiao)。

原因二：防塵圈在裝配時，沒有(you)做(zuo)好(hao)相應的保護(hu)措(cuo)施(shi)，使(shi)得(de)其唇口有(you)殘留的油漆，進(jin)而影響(xiang)到防塵效果。
