How to Distinguish Whether Industrial Lubricating Oil Has Deteriorated?

Steam turbine oil, bearing lubricating oil, hydraulic oil, gear oil, machine tool lubricating oil, grease, metalworking fluid, textile lubricating oil, quenching oil, heat transfer oil, electrical oil, refrigeration oil, antirust oil, etc.

220# gear oil manufacturers are widely used in industry and are generally familiar to people.

Because of the large demand, the storage of industrial lubricating oil is not easy.

If it deteriorates, it must not be used.

How can we distinguish whether industrial lubricants have deteriorated?

ow can we distinguish whether industrial lubricants have deteriorated

The deterioration of industrial lubricants will be dark in color, with more foam and emulsification.

We can also use finger polishing to distinguish.

For example, no greasy feeling, peculiar smell, or more melanin or dark brown can prove that the oil has deteriorated.

If the deteriorated industrial lubricating oil is used, the parts will be damaged, affecting the service life of the machine, and safety accidents may occur at serious points.

We should be cautious, and we should often check whether the oil is deteriorated and replace it in time.

So what methods can be used to identify the deterioration of industrial lubricants? These are some of them.

1. Observation method

By taking two measuring cups, one is filled with lubricating oil and the other is not filled with lubricating oil, then lift the measuring cup with lubricating oil up to the height of three cups, pour it into the empty cup obliquely, and finally observe the lubricating oil.

Good quality industrial lubricating oil will flow into the empty cup evenly, slender and continuously.

If the quality is poor, it will be fast and slow, and sometimes large pieces are left, which can indicate that it has deteriorated.

2. Finger grinding method

Grind the lubricating oil through the thumb and index finger.

After repeated grinding, it can be judged by the lubricity, degree of friction and the amount of wear debris of the lubricating oil.

A good lubricating oil will have good lubricity, with few wear debris and no sense of friction.

However, if particles are found during friction, it indicates that there is a problem with the oil, which cannot be used and should be replaced in time.

3. Sunlight exposure method

The industrial lubricating oil can be stuck on it with a screwdriver, and then tilted at an angle of 40 degrees, so that the oil can slowly fall along the tip of the screwdriver in the sun, and observe the oil droplets.

The oil under the light can clearly see whether there is wear debris.

If there is no wear debris, it is proven to be good;

If there are abrasive chips and there are too many abrasive chips, it is recommended to replace them.

4. Filter paper trace method

Prepare a clean white filter paper, drop a few drops of lubricating oil onto the filter paper, wait for the lubricating oil to leak out, then observe whether there is black powder, and then touch with your fingers to see whether there is a sense of blockage.

If there are many magazines, they need to be replaced;

Good lubricating oil should be non-powder.

The finger touch is smooth and the color is yellow, indicating that there is no problem with the lubricating oil.
