如何(he)合理地使(shi)用油封，應注意以下幾點：

1.軸的轉(zhuan)速(su)由于(yu)(yu)設(she)計和結構上的原(yuan)因，高(gao)轉(zhuan)數(shu)的軸應使(shi)用高(gao)速(su)油(you)(you)封，低轉(zhuan)速(su)的軸使(shi)用低速(su)油(you)(you)封，不能將低速(su)油(you)(you)封用于(yu)(yu)高(gao)速(su)軸上，反之也不行。

2.環境溫度在使用(yong)溫度較高(gao)的(de)情(qing)況下，應(ying)選(xuan)用(yong)聚丙烯(xi)酯或硅、氟(fu)、硅氟(fu)橡(xiang)膠。并應(ying)設法降低油箱中的(de)油溫。在使用(yong)溫度過(guo)低的(de)情(qing)況下，應(ying)選(xuan)用(yong)耐寒橡(xiang)膠。

3.壓(ya)力(li)(li)一般的(de)(de)油(you)封(feng)承(cheng)受壓(ya)力(li)(li)能(neng)力(li)(li)差，壓(ya)力(li)(li)過(guo)大時油(you)封(feng)會變(bian)形。在壓(ya)力(li)(li)過(guo)大的(de)(de)使(shi)用(yong)條件下應采用(yong)耐壓(ya)支(zhi)承(cheng)圈或(huo)加強的(de)(de)耐壓(ya)油(you)封(feng)。

4.安裝上的偏(pian)心程度油封(feng)(feng)和軸配合時(shi)(shi)偏(pian)心過(guo)大，則其密封(feng)(feng)性會變差，特別(bie)是(shi)在軸轉速(su)高時(shi)(shi)尤為(wei)嚴重。如果偏(pian)心過(guo)大時(shi)(shi)，可采用“W”形(xing)斷面的油封(feng)(feng)。

5.軸(zhou)的(de)表面(mian)光潔度，直接影響油封(feng)(feng)的(de)使用(yong)壽命，即軸(zhou)的(de)光潔度高，油封(feng)(feng)使用(yong)壽命就會長。

6.注意(yi)在油封的唇口應有一定量的潤滑油。

7.要特別(bie)注(zhu)意防止(zhi)塵土浸入油(you)(you)封(feng)。TB： 雙(shuang)唇， 有安裝彈簧(huang) ，外(wai)殼鐵殼；青海TC骨架油(you)(you)封(feng)常見問題(ti)

為(wei)(wei)了充分(fen)發(fa)揮(hui)油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)功能，必須根據使(shi)用(yong)條(tiao)件(jian)(jian)選(xuan)定(ding)合適的(de)(de)(de)型(xing)式與(yu)材(cai)(cai)料(liao)。這里(li)就主要的(de)(de)(de)影響因素(su)作(zuo)(zuo)(zuo)一簡述。1、軸(zhou)的(de)(de)(de)表(biao)(biao)面(mian)線(xian)速(su)度(du)(du)(du)：在(zai)同一直(zhi)徑(jing)條(tiao)件(jian)(jian)下(xia)，不(bu)同材(cai)(cai)料(liao)制造的(de)(de)(de)油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)，適應(ying)軸(zhou)面(mian)旋轉線(xian)速(su)度(du)(du)(du)的(de)(de)(de)能力不(bu)同。油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)使(shi)用(yong)的(de)(de)(de)線(xian)速(su)度(du)(du)(du)范圍一般小于(yu)(yu)(yu)15m/s,滿(man)意的(de)(de)(de)潤滑和良好的(de)(de)(de)散熱(re)條(tiao)件(jian)(jian)才是決定(ding)性因素(su)。相應(ying)較低的(de)(de)(de)數據，適用(yong)于(yu)(yu)(yu)更為(wei)(wei)苛刻的(de)(de)(de)條(tiao)件(jian)(jian)。2、溫(wen)(wen)度(du)(du)(du)：由于(yu)(yu)(yu)旋轉軸(zhou)表(biao)(biao)面(mian)與(yu)油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)唇(chun)(chun)(chun)部(bu)(bu)產生摩(mo)擦，所(suo)以密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)唇(chun)(chun)(chun)口(kou)部(bu)(bu)的(de)(de)(de)溫(wen)(wen)度(du)(du)(du)高(gao)(gao)于(yu)(yu)(yu)油(you)(you)(you)(you)(you)液中的(de)(de)(de)溫(wen)(wen)度(du)(du)(du)，一般油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)工(gong)作(zuo)(zuo)(zuo)時其(qi)唇(chun)(chun)(chun)緣的(de)(de)(de)溫(wen)(wen)度(du)(du)(du)高(gao)(gao)于(yu)(yu)(yu)工(gong)作(zuo)(zuo)(zuo)介質(zhi)溫(wen)(wen)度(du)(du)(du)20~50℃。隨著轉速(su)和壓(ya)(ya)力增加(jia)，密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)唇(chun)(chun)(chun)口(kou)處的(de)(de)(de)溫(wen)(wen)度(du)(du)(du)也隨之(zhi)上升。另外，帶有防(fang)塵唇(chun)(chun)(chun)的(de)(de)(de)油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)，比無(wu)(wu)防(fang)塵唇(chun)(chun)(chun)的(de)(de)(de)油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)會出現高(gao)(gao)于(yu)(yu)(yu)20℃的(de)(de)(de)過(guo)高(gao)(gao)溫(wen)(wen)度(du)(du)(du)。當超過(guo)容許(xu)溫(wen)(wen)度(du)(du)(du)時會縮短油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)工(gong)作(zuo)(zuo)(zuo)壽命，造成(cheng)密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)唇(chun)(chun)(chun)過(guo)早硬(ying)化及磨損加(jia)大。油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)的(de)(de)(de)工(gong)作(zuo)(zuo)(zuo)溫(wen)(wen)度(du)(du)(du)范圍與(yu)油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)使(shi)用(yong)的(de)(de)(de)材(cai)(cai)料(liao)有關：材(cai)(cai)料(liao)為(wei)(wei)丁晴橡(xiang)膠(jiao)(jiao)（NBR）時為(wei)(wei)-40~120℃，亞力克橡(xiang)膠(jiao)(jiao)（ACM）-30~180℃，氟橡(xiang)膠(jiao)(jiao)（FKM）-20~230℃。3、壓(ya)(ya)力：油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)主要用(yong)于(yu)(yu)(yu)無(wu)(wu)壓(ya)(ya)或者在(zai)微(wei)壓(ya)(ya)的(de)(de)(de)條(tiao)件(jian)(jian)下(xia)使(shi)用(yong)，工(gong)作(zuo)(zuo)(zuo)壓(ya)(ya)力不(bu)超過(guo)0.05Mpa。當工(gong)作(zuo)(zuo)(zuo)壓(ya)(ya)力超過(guo)這個值時應(ying)選(xuan)用(yong)耐壓(ya)(ya)型(xing)油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)。4、防(fang)塵：為(wei)(wei)防(fang)止污染物(wu)、灰塵、和濕氣等從(cong)空氣側(ce)進入密(mi)(mi)封(feng)(feng)(feng)(feng)(feng)腔體(ti)內，建議(yi)(yi)使(shi)用(yong)帶有防(fang)塵唇(chun)(chun)(chun)的(de)(de)(de)油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)。如果(guo)污染物(wu)侵入嚴(yan)重(zhong)建議(yi)(yi)采(cai)用(yong)2個油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)，以串聯(lian)方式一前一后安(an)裝。上海耐腐蝕油(you)(you)(you)(you)(you)封(feng)(feng)(feng)(feng)(feng)定(ding)制
