A question about lubricating the bearing housing
Thread Content
Under normal circumstances, the bearing housing should be filled with oil to a level of 1/2 to 2/3 of the oil sight glass. If too much oil is added, will this cause the oil seals at both ends of the bearing housing to leak? Is it normal for the bearing housing to leak oil when too much oil is used? Does adding too much oil necessarily lead to leakage, or is leakage only possible in such cases? ? {:1_90:}
If too much oil is used, there will definitely be leakage in the case of a labyrinth seal; however, there will be no leakage with a skeleton oil seal!
Generally, adding too much oil will cause leaks. Moreover, an excess of oil increases the resistance for rotating components as well as hinders heat dissipation; filling the tank to the standard level is the most scientific and economical approach
What I’ve encountered is that too much oil is used in the seal for the frame; this leads to oil leakage, especially in summer. However, the seals that come from the manufacturer don’t cause such leakage, while those purchased separately do
Consider the type of sealing used on the end cover of the bearing box. It is also important to pay attention to the fit between the pump shaft and the end cover seals, as wear occurs to the shaft over time. AIG offers a mechanical seal that works well when used at the end cover, helping to eliminate troublesome leakage problems; however, it is more expensive. When using this type of seal, be careful when adding or topping up oil, making sure that the oil level does not exceed two-thirds of the bearing box’s capacity. It is also advisable to have cooling water available for the bearing box, as otherwise heat dissipation will be affected. The choice of end cover sealing method depends on the initial design of the equipment, such as whether the bearing box relies on active or passive cooling methods. Try to avoid making arbitrary changes
Add fuel in moderation; oil leakage is not allowed.
Too much oil can cause the temperature to rise excessively, increasing the degree of damage to the bearings
Use fluoropolymer adhesive – get a quality one! Nitrile rubber is cheap, but it’s too hard! Next, check whether the matching set is uneven; the pore covers must allow air to pass through!
Thank you, I’ll tell the purchasing staff when I buy next time
