渣漿泵本身帶推力軸承的結(jié)構(gòu)
國內(nèi)某LC型立式長軸泵用軸承結(jié)構(gòu)，
國內(nèi)某TC型立式單級單吸懸臂式液下泵結(jié)構(gòu)，，相當(dāng)于臥式單級單吸懸臂式軸承結(jié)構(gòu)立式用。
推力滾動軸承潤滑
干油潤滑干油潤滑注油杯加油， 推薦ZN-3鈉基潤滑脂或鋰基潤滑脂
浸沒式稀油潤滑浸沒式稀 油潤滑如所示。對于立式泵而言，滾動體應(yīng)浸沒-定深度，以浸沒滾珠2/3為宜。
自循環(huán)稀油潤滑 自循環(huán)稀油潤滑如。
Other thrust rolling bearing structures
Bearing structure for a domestic LC type vertical long shaft pump,
The structure of a TC type vertical single-stage single suction cantilever submerged pump in China is equivalent to that of a horizontal single-stage single suction cantilever bearing structure.
Lubrication of thrust rolling bearing
Dry oil lubrication Grease filling cup, ZN-3 sodium base grease or lithium base grease is recommended
Immersion thin oil lubrication Immersion thin oil lubrication is shown in. For vertical pumps, the rolling element shall be immersed to a certain depth, and it is better to immerse 2/3 of the ball.
Self circulating thin oil lubrication.
When the shaft rotates, a bowl at the lower part of the rolling bearing sleeve rotates with it, forcing the oil subjected to centrifugal force into 6-8 oil holes), rising above the rolling bearing, and then returning to the oil pool at the bottom of the bearing body after passing through the rolling bearing. The circulation of lubricating oil not only makes the rolling bearing lubricated, but also cools the lubricating oil
But. If necessary, the oil pool can be cooled by adding a serpentine tube (see Figure 55) or by adding a cooling water jacket to the oil pool.
(4) The lubricating oil level shall be displayed by oil cup or oil pointer. The upper part of the thin oil lubricated bearing body shall be provided with a vent plug, and the bottom shall be provided with an oil drain plug.
(5) The thrust sliding bearing at the end of vertical pump is not introduced here because it is rarely used and complicated. At this time, the motor is often allowed to bear the axial force and the mass of the pump rotor.
當(dāng)軸旋轉(zhuǎn)時，滾動軸承套下部有個碗形 也隨著旋轉(zhuǎn)，迫使受離心力的油進人油孔一般6-8個) 并上升到滾動軸承上方，然后經(jīng)過滾動軸承后返回到軸承體底部的油池中。潤滑油循環(huán)，不僅使?jié)L動軸承得到潤滑，而且潤滑油同時也被冷
卻。需要時，油池可以加蛇形管冷卻(見圖55)也可在油池外加冷卻水套冷卻。
(4)潤滑油面應(yīng)采用油杯或油標(biāo)顯示。稀油潤滑 的軸承體上部應(yīng)設(shè)置放氣塞，底部應(yīng)設(shè)置放油塞。
(5)立式泵端推力滑動軸承由于用得少，也復(fù)雜，這里不予介紹。此時往往讓電動機來承受軸向力及泵轉(zhuǎn)子的質(zhì)量。
