In the previous article, we introduced the importance of hydraulic system in the maintenance of the cone crusher. So how to judge whether we need to replace the hydraulic oil? Timely replacement of hydraulic oil can ensure the stability of the operation of hydraulic system, making the efficient operation of the cone crusher. The replacement of hydraulic oil needs to see the following "Three Elements":

1. Degree of oxidation

Usually the color of new hydraulic oil is relatively bright, no obvious odor, but with the extension of the use time, and high-temperature oxidation, the oil color gets darker. If found that the color of the cone crusher hydraulic oil is black brown, and accompanied by odour means that the oil has been oxidized, need to replace the new oil.

2. Water content

Water content. The water content of cone crusher hydraulic oil will affect its lubrication performance. When there is a large amount of water mixed into the hydraulic oil, the mixture will form a muddy mixture, at this time we need to replace the hydraulic oil, to avoid affecting the performance of the cone crusher.

3. Impurity content

Impurity content. When cone crusher works, due to the continuous collision and grinding between the parts, it is easy to produce debris, inevitably enter into the hydraulic oil. If the hydraulic oil contains a lot of impurities, it not only declines the quality, but also may cause damage to the cone crusher parts. Therefore, after using the hydraulic oil for a period of time, you must pay attention to check the content of impurities in the hydraulic oil.

The cone crusher produced by Luoyang Dahua mainly includes single-cylinder hydraulic cone crusher and multi-cylinder hydraulic cone crusher. The model is complete, and the maximum processing capacity can reach 1200 t/h. Among them, the small cone crusher can be used for mobile crushing station, and GPY800 cone crusher is used for steel slag crushing.
