Questions regarding lubricant emulsification and replacement
Thread Content
Our company currently has several Roots pumps, and during commissioning, oil emulsification occurred. During oil drainage, it was left to stand for over an hour before oil was added again, and emulsification occurred once more. I would like to ask whether, in this situation, it is necessary to clean the gears with oil before refilling them. How can the residual oil inside the gearbox be completely removed? ? Or is it not a problem with the oil, but rather an issue with the sealing of the equipment?
It needs to be rinsed with oil several times or the oil should be filtered online using a water removal device.
Does the oil tank of the Roots pump come with water cooling? If it does, it is necessary to check for any leaks between the water channels and the lubricating oil chamber
Check the seal; it’s not necessarily a problem with the lubricant itself – take another look at the entire system
Well, I’ll give it a few washes first to see.
It has water cooling, and it’s quite troublesome to disassemble the pump; I’ll try changing the oil first.
It probably has nothing to do with the oil; it’s better to check the water cooling channels or the mechanical seal. How the water gets in is the key!
If there is residual lubricating oil inside and it emulsifies in a short period of time, this may be related to a seal leak.
I cleaned it with oil in the afternoon; there was very little residue left, so it must have leaked. .
