What should the dn be on a pump bearing housing?
A typical pump bearing housing with oil level reaching to the center of the lowermost rolling elements. Here, keeping the DN values below 6,000 reduces the risk of oil overheating. A bearing housing with lower oil level and intended for DN values in excess of 6,000 is shown in Figure 2.
Where is the oil level on a pump bearing?
Attention should be given to oil levels needed and maintained in pump bearing housings. At relatively slow shaft speed/shaft diameter combinations, the oil level is adjusted to reach the center of the balls (or rollers) located at the 6 o’clock position of the bearing.
What kind of lubrication is used for pump bearing housing?
In pure mist lubrication, the oil/air mist is fed under pressure to the housing. There is no reservoir of oil in the housing and oil rings are not used. Purge mist lubrication utilizes the same principles of pure mist, but a reservoir of oil in the housing exists. A slinger/flinger disc or oil rings can also be used to provide splash lubrication.
Do you put an oil ring on the bottom of the pump?
An oil ring in as-new (wide and chamfered) condition on the bottom, and one in abraded (narrow and chamfer-less) condition on the top. Cooling is still found in pumps with high speed and heavily loaded rolling element bearings.
