How to determine the time for replacing oil in Roots blower

In Roots blower, lubricating oil has the functions of lubrication, reducing friction, cooling, protection, and washing. After a period of use, lubricating oil may experience pollution, aging, and reduced leakage. Therefore, in general, various fan equipment will have corresponding replacement cycles set according to actual usage.

Of course, in practical applications, whether a Roots blower needs to replace lubricating oil does not necessarily have a fixed cycle. Depending on the performance of the oil, the cycle may become shorter or longer. Changing too early will increase the cost of use, while changing too late will affect the performance of the Roots blower. Ultimately, the specific quality of the lubricating oil depends on the actual situation, and its judgment can be made through several aspects:

Check for oxidation and deterioration. On the one hand, this can be distinguished by appearance to see if the color of the oil has turned black or deepened, and if there is a hard adhesive film formed on the surface. On the other hand, a small amount of oil sludge from the bottom of the fuel tank can also be placed between the index finger and thumb for twisting and friction. If you feel a lot of gum and strong adhesion, it indicates that the lubricating oil has seriously deteriorated and needs to be replaced.

The second is to check whether the lubricating oil has been mixed with a large amount of hard particles and impurities. This is the same as the above inspection method, by taking a small amount of lubricating oil and twisting it with your fingers, you can make a judgment based on your sensation.

If it is necessary to replace the lubricating oil, it is necessary to avoid mixing the old and new lubricating oils. After removing the old oil, fill it with new oil. In addition, during the filling process, pay attention to the amount of oil.
