Questions regarding the sealing of ordinary centrifugal pumps and bearing box cooling!
Thread Content
With the medium temperature at around 40 to 50 degrees, is it necessary to use circulating cooling water for ordinary centrifugal pumps? Including bearing housing cooling. In winter, the temperature is below zero degrees, while in summer it ranges from 30 to 40 degrees. Currently, the measured temperature of the pump seal is around 20 degrees, and the temperature of the bearing housing is around 15 degrees
It is recommended to check the pump’s speed, flow rate, and head. I have never seen a pump bearing chamber equipped with cooling water; at most, there are cooling channels in the bearing housing and the cover surrounding it
Bearing housings cooled by jackets or coils are generally suitable for high-temperature pumps; there is no need to use this approach in the situation you mentioned.
Whether a bearing requires cooling water is determined by a combination of the bearing’s radial load, axial load, equipment speed, and ambient temperature.
If the power is not high, forced air cooling can be considered.
Based on what you’ve said, it seems that there’s absolutely no need for circulating water cooling. The circulating water in our factory is extremely dirty; we have to clean the cooling system lines frequently during winter, which leads to endless problems
I don’t think this question is necessary!
The temperature isn’t high, so there’s no need for cooling water; these days, energy conservation and reduced consumption are important.
It’s not necessary; the fins on the bearing housing are sufficient for cooling. If the temperature of the medium exceeds 120°C, cooling for both the base and the bearing housing is required.
In your case, there’s no need to apply it, but make sure to clean it thoroughly to avoid it cracking from the cold
