Once the bearing comes into contact with water, the lubricant becomes emulsified, which reduces its lubricating performance. This can negatively impact the lubrication of the backup roller, leading to issues such as rust and abnormal wear. As a result, the oil film bearing operates under poor lubrication conditions, which seriously affects production efficiency and increases maintenance costs.
To ensure the smooth and reliable operation of the equipment, two key measures have been taken. First, the sealing system of the oil film bearing has been improved to prevent water ingress. Second, a Guangxi lampblack purifier is used in conjunction with a vacuum oil purifier to remove moisture that has entered the oil film bearing system, thereby reducing the water content in the oil.
The vacuum oil purifier works based on the difference in boiling points between water and oil under a certain level of vacuum. Contaminated oil is drawn into the system by an oil suction pump. A temperature sensor then checks the oil’s temperature. If it is below the set point, an infrared heater is activated to warm the oil. If the temperature is already above the set value, the heater remains off.
Once the oil reaches the desired temperature, it flows into the oil-water separation chamber and the vacuum separation chamber. These chambers are sealed containers that maintain a vacuum environment created by a vacuum pump. Under this vacuum, the boiling point of water drops significantly compared to that of oil. As a result, moisture and gaseous impurities in the contaminated oil evaporate and separate from the oil. The vaporized water and gases, along with the purified oil, move into the vacuum separation chamber for further processing before being returned as clean oil.
This process ensures that the oil remains free from contaminants, improving the overall performance and lifespan of the bearing system.
