如何合理地使用油封，应注意以下几(ji)点(dian)：

1.轴的(de)转(zhuan)速(su)由于(yu)(yu)设计(ji)和结构上的(de)原因，高转(zhuan)数的(de)轴应使(shi)用(yong)高速(su)油(you)封，低(di)(di)转(zhuan)速(su)的(de)轴使(shi)用(yong)低(di)(di)速(su)油(you)封，不能将低(di)(di)速(su)油(you)封用(yong)于(yu)(yu)高速(su)轴上，反之(zhi)也不行。

2.环境温度在(zai)使(shi)用(yong)(yong)温度较高(gao)的情况下，应选用(yong)(yong)聚丙(bing)烯酯或硅(gui)、氟(fu)、硅(gui)氟(fu)橡胶。并应设法降低油箱中的油温。在(zai)使(shi)用(yong)(yong)温度过低的情况下，应选用(yong)(yong)耐寒(han)橡胶。

3.压(ya)(ya)力一般(ban)的(de)油(you)(you)(you)封承受压(ya)(ya)力能力差，压(ya)(ya)力过(guo)大时油(you)(you)(you)封会变形。在压(ya)(ya)力过(guo)大的(de)使用(yong)条(tiao)件下应采用(yong)耐(nai)压(ya)(ya)支承圈或加强的(de)耐(nai)压(ya)(ya)油(you)(you)(you)封。

4.安装上的(de)偏(pian)(pian)心程度油封(feng)和(he)轴(zhou)(zhou)配合(he)时(shi)偏(pian)(pian)心过大，则(ze)其密封(feng)性会(hui)变差(cha)，特别是在轴(zhou)(zhou)转速高时(shi)尤(you)为严重。如果(guo)偏(pian)(pian)心过大时(shi)，可采(cai)用“W”形断面的(de)油封(feng)。

5.轴的表面光洁度(du)，直接影响油(you)封的使用寿(shou)命，即轴的光洁度(du)高，油(you)封使用寿(shou)命就会长。

6.注意在油封(feng)的唇(chun)口应(ying)有(you)一定量的润(run)滑油。

7.要特别注意防止(zhi)尘土浸入油封。TB： 双(shuang)唇， 有安装弹簧 ，外(wai)壳铁壳；青海(hai)TC骨架油封常见问题
