When the hydraulic oil turns dark brown and emits an odor, or a turbid water-oil mixture or impurities accumulate, it must be replaced immediately, otherwise it will seriously affect the lubrication performance of the cone crusher, aggravate component wear, and threaten the stable operation of the entire production line.

After the ore processing production line has been running for a long time, for the cone crusher, the hydraulic system is an important condition to ensure the smooth production of the cone crusher, and plays an important role in the lubrication of the equipment. The hydraulic system uses hydraulic oil, which needs to be replaced every once in a while. When replacing, the state of the hydraulic oil needs to be judged. Generally speaking, there are three judgment criteria. When one of them is reached, the hydraulic oil cannot assist the smooth production well, and it needs to be replaced. Here are the three judgment criteria.

Judgment criteria 1. Oxidation degree

Generally speaking, the color of new hydraulic oil is relatively light and there is no obvious odor. However, as the use time increases and the high temperature oxidation during use, the color gradually deepens. If the hydraulic oil in the hydraulic system of the cone crusher is dark brown and accompanied by a bad smell, then it is necessary to replace the new hydraulic oil;

Judgment criteria 2. Water content

The amount of water in the hydraulic oil of the cone crusher will affect its lubrication performance. If a large amount of water enters the hydraulic oil, since water and oil do not mix, a turbid mixture will be formed when mixed. In order to ensure the working performance of the equipment, the hydraulic oil needs to be replaced. Replacement;

Judgment criteria three, impurity content

During the working process of the cone crusher, due to the continuous collision and grinding between the components, it is easy to produce debris, which will inevitably enter the hydraulic oil. At this time, the hydraulic oil contains impurities, which will not only reduce the quality of the hydraulic oil, but also cause damage to the equipment parts. Therefore, when the impurities reach a certain content, the hydraulic oil needs to be replaced;

The article mainly introduces three judgment methods for the replacement of the hydraulic oil of the cone crusher, mainly the degree of oxidation, water content and impurity content. When one of these three judgment criteria is met, the hydraulic oil needs to be replaced to ensure the performance of the hydraulic oil and the smooth operation of the equipment.
