The selection of agricultural machinery oil must be careful, try to choose good quality products. Because the quality of agricultural machinery oil will affect the use of agricultural machinery to a certain extent. The long-term use of oil with poor quality will have a bad effect on agricultural machinery and will probably shorten the service life of agricultural machinery. Then, how to identify the quality of agricultural oil? The following four points may help:
1, see: look at the appearance of oil products. Different kinds of oils have different color appearances. Carefully observe the appearance color of the oil, the color is pale, mostly light fractions and deep refined oils, dark in color, mostly residual oils, oils with low degree of refinement, or heavy distillate oils. .
2, smell: smell the smell of oil products. The smell of oil is generally divided into gasoline, kerosene, diesel, alcohol, aromatic, sour, and so on. The oil added with additives has a certain sourness; the oil with alcohol composition has alcohol taste; the light solvent oil has aromatic flavor.
3. Shake: After shaking, observe the degree of thickening of the oil. By shaking the oil in a colorless glass bottle and observing the phenomenon of oil film hanging and the occurrence and disappearance of air bubbles, different grades of oil can be basically distinguished. Small-viscosity oils produce more bubbles, rise faster, disappear faster, and have less hanging bottles; oils with large viscosity produce less bubbles, slower rise speeds, and slower disappearance, but more oil is hung on bottles.
4, touch: used to touch the soft and hard oil conditions and smooth sense. The refined oil hand mold has a strong sense of smoothness, and poorly refined oil has a poor smooth feel. The grease and the hardness can be divided into different grades. The smaller ones are softer, and the larger ones are harder.
