What is the reason for many bubbles coming out of the lubricating oil tank?
1 Oil overheating. 2 Air in the oil tank. Impact splashing of the 3rd oil return.
Has the lubricant become emulsified? When lubricant comes into contact with water or contains water, vapor is generated and bubbles form. A high temperature of the lubricant can also lead to similar situations, but this has not been observed; however, it can occur when too much lubricant is used and the temperature is very high. The quality of the lubricant may be unstable, or lubricant that is not suitable for this pump may have been used – the correct grade of lubricant may not have been used either. In most cases, water getting into the lubricant is the cause; there are many ways for water to get in, such as through poor or damaged seals, into the cooling water, or as a result of cleaning activities at the site. The lubricant itself may also contain unacceptable amounts of water
1. Air in the oil 2. Poor quality of the oil 3. Water in the oil
1. Air or process gas present in the oil. 2. Poor quality of the oil itself. 3. Water present in the oil, along with excessively high oil temperature
Caused by water or gas entering the oil； Caused by high oil temperature ； Analyze the oil quality and take prompt action to address the issues, thereby preventing accidents.
Check whether the oil vent of the tank is blocked.
1. Incorrect oil used 2. Oil has deteriorated 3. Poor cooling 3. Water has entered the oil
(1) Gas or water present in the oil causes oxidation and foaming of the oil； (2) A too high liquid level in the fuel tank can also cause such consequences ； (3) The return pipeline to the oil tank is unreasonable, causing oil to splash out ； (4) There is a problem with the quality of the oil ；
Which parameters need to be tested? Moisture, acidity
There may be water at most; an oil injection purification device is used.
1. Medium gases carried back into the fuel tank; 2. Poor quality of the oil; 3. Excessive nitrogen flow at the bottom of the fuel tank
Thank you all for your replies; I’ve learned a lot!!
The lubricating oil has mixed with air, and the air can be removed through the vent valve. This post was last edited by fengying_08 on 2009-3-9 at 11:43

One is that the oil has emulsified, and the other is that the oil level is too high, allowing air to get in:handshake
Check the oil pump inlet pipeline for air leaks.
