如何檢查滾動等截面軸承潤化油脂是否發霉

时间:2021-01-14     

如何檢查滾動等截面軸承潤化油脂是否發霉


1.太陽光照射法


在艷陽高照的日常生活,應用螺絲起子除去油脂,隨后飛到四十五度。與太陽光對比,觀察液滴情況,太陽底下,能夠清晰地見到潤滑脂中沒有碎屑是出色的,能夠再度充分發揮實際效果,碎屑太多時,務必拆換潤滑脂。


2.液滴劃痕法


取一張整潔的白濾紙,濾紙上滲油少量,油脂泄露后,假如表層有黑色粉末,與手觸碰時有抵御感,說明油脂內沉渣多,油脂無粉末狀,干躁清理,且印痕淡黃。


3.油排觀察


拿2個量杯,一個放滿油脂待檢,一個空在桌面。將配有油的量杯從桌面移除30至40厘米,并歪斜,容許油脂注入空杯并觀察其流通性。性能卓越價格對比的潤滑脂更長、細、勻稱、持續。油脂排出來快,排出來慢,便說油脂發霉了。


4.手捻法


將油脂擰在大拇指和左手無名指中間,不斷碾磨。油脂觸感好,潤滑性好,磨壞碎屑少,無磨擦。假如覺得手指頭正中間像小石子一樣有非常大的滑動摩擦力,表明油脂中有很多殘余物,不可以多次重復使用。拆換新的潤滑脂。
