高壓防爆電機滾動軸承的維護與保養(yǎng)
儲存期超過半年或停機超過2個月后再次使用的防爆電機,應檢查軸承裝置的狀況。如有嚴重污染、無油、油干、零件銹蝕等狀況時,需將防爆電機的軸承裝置進行解 體,徹底清洗軸承及與軸承相關的部件,然后重新加注潤滑脂。加注時,滾動軸承內部應加滿潤滑脂,軸承內 蓋與軸承外蓋所形成的空腔的填脂量為整個空腔的1/3-1/2。潤滑脂經過一段時間使用以后,特性會變差,潤滑功能會降低,因此要適時補充潤滑脂。潤滑脂補充的時間間隔與補充數量打在防爆電機的注油牌上,應按照注油牌數據及時補充潤滑脂,才能保證滾動軸承的可靠運行。注油牌上的加油周期及數量適用于軸承70℃及以下工作狀態(tài),但當軸承溫度超過70℃時,軸承溫度每上升15℃,潤滑脂的補充間隔時間減少一半。在設備定期檢修時,為了防爆電機在下一檢修周期內的可靠運行,應拆檢軸承裝置,必要時更換軸承(圖\文brfr.com.cn/)。

Stored for more than six months or stop over again 2 months later using explosion-proof motor, should check the bearing device status. If any serious pollution, no oil, oil dry, component corrosion status, the explosion-proof motor bearing device for body, thorough cleaning bearings and bearing and related components, and then to fill grease. Add, interior of the rolling bearing should be filled with grease, bearing inner cover and the outer bearing cover of the cavity formed by the filling grease amount for the entire cavity 1/3-1/2. Grease after a period of use, performance will deteriorate, lubricating function can be reduced, so as to timely supplement of lubricating grease. Grease replenishment interval and amount of added in explosion-proof motor oil brand, should be in accordance with the oiling card data timely replenishment of grease, in order to ensure the reliable operation of the rolling bearing. Oiling card gas cycle and the number of applicable bearing 70 ℃and under working state, but when the bearing temperature over 70 ℃, bearing temperature rises every 15 ℃, lubricating grease added interval halving. In the regular equipment maintenance, in order to explosion-proof motor in the next overhaul period and reliable operation, should be overhauled bearing device, when necessary, replacement of bearings.承。
