Centrifugal pump oil emulsification problem
Thread Content
Hello, everyone! What causes oil emulsification in centrifugal pumps, and how can this problem be solved? Thank you
Water entering the oil is the main cause; first, contain the water, thoroughly clean the oil chamber, and replace it with new oil.
Furthermore, and more importantly, it is necessary to find the source of the water, such as leaks from equipment like coolers. After changing the oil, address the leak promptly to prevent the oil from emulsifying there.
I think the oil temperature is also a factor to consider. Add an oil cooler.
There are two reasons. Oil temperature too high or water leakage.
Reply to 4# yuhongtao05: I would like to ask, why does emulsification occur when the oil temperature rises? I only know that water seepage will emulsify. Thank you first
Emulsification can also occur when the oil temperature is low. In some cases, it is inevitable for water from the working medium to end up in the oil, and under intense stirring, this can lead to emulsification and deterioration of the oil. Machines often have heaters or temperature control valves to maintain the temperature of the lubricating oil. If the heater is damaged or the temperature controller fails, it can lead to a low oil temperature and thus emulsification; I have not seen emulsification occur due to high temperatures. Generally speaking, high temperatures help to eliminate emulsification and foaming.
Reply to 6# Kuju Kaisei: Haha, a chemical reaction took place, it changed texture and turned into a milky white liquid. Generally speaking, emulsification is a physical phenomenon, right?
Indeed, I’m also wondering – how high does high oil temperature refer to? Above 100°C? I really have never seen oil emulsification occur when the oil temperature is high.
Low oil temperature or water entering the oil system
Water enters the bearing box, or the temperature of the bearing box is high
