How to quickly identify whether the air compressor lubricant needs to be replaced?

Lubricating oil is essential when air compressor is running. How to quickly identify whether air compressor lubricating oil needs to be replaced?Let Xiaobian tell you that there are mainly the following points:

I. Oil Flow Observation

Take two measuring cups, one empty on the desktop and the other containing the air compressor oil to be checked. Lift the measuring cup filled with lubricant 30-40 cm away from the desktop and tilt it to let it flow slowly into the empty cup. Observe its flow condition. Good quality lubricant flow should be long, uniform and continuous. If oil flow occurs slightly or slightly, then large pieces will flow down.The oil has deteriorated.

II. Hand twisting

Repeated twisting of air compressor oil with thumb and index finger indicates that there are more impurities in the compressor oil and a new compressor oil needs to be replaced if the hand feels lubricant, less wear debris and no friction, and if greater friction such as sand particles between the fingers is felt.

III. Light method

On sunny days, use a screwdriver to lift the air compressor oil at a 45 degree angle to the level.Contrast with sunlight and observe the condition of oil drops. Under sunlight, it can be clearly seen that no wear debris in oil is good and can continue to work. If there is too much wear debris, replace the empty part.

IV. Oil drop tracing method:

Drip a few drops of compressor oil onto the white filter test paper. After the pressure oil leaks, if there is black powder on the surface and there is a feeling of obstruction when touched by hand, it means that there are many impurities in the lubricant. If the hand feels dry and smooth without powder and shows yellow marks, it means that it is a good oil.
