The hydraulic oil is the power transmission carrier of the hydraulic system, and has a certain lubrication effect. Therefore, the cleanliness, performance parameters and the like of the hydraulic oil directly influence the use of the hydraulic components, thereby affecting the working performance of the equipment.

How to deal with the hydraulic oil when it becomes turbid?
Many of the machine owners have encountered the hydraulic oil to become turbid, the impurities in the hydraulic oil are not well cleaned, and the following will be described in detail below.
Cause 1
The first reason why the oil is turbid is that the hydraulic oil is doped with water, and a small test can be made to drop a few drops of hydraulic oil on a piece of hot steel plate to check whether the oil is mixed with water in the oil. If the air bubble can be observed clearly, it can be determined that the hydraulic oil contains water. If the oil is a new replacement time, the oil will be allowed to settle to the bottom. If the oil is close to the oil change time, the oil can be changed directly.
Cause 2
When the hydraulic oil is mixed with air, first, if air is mixed in the hydraulic oil, the phenomenon of white turbidity will be present. At this time, the owner should focus on whether the hydraulic pipeline has air leakage, and cut off the possibility of air entering from the source.
Cause 3
Do you want to mix the hydraulic oil? In strict sense, the hydraulic oil of different labels and different brands is not miscible, especially the hydraulic oil with variable price, which is likely to cause the oil to become turbid after mixing, thus causing damage to the hydraulic components. When selecting hydraulic oil, it is necessary to select the type of hydraulic oil according to the working environment and working conditions. When the hydraulic oil is selected, the hydraulic oil shall be comprehensively considered from the working pressure, temperature, environment, hydraulic system and the structure and material of the components and the economy. When the working pressure is relatively large, the lubricating property and the abrasion resistance of the hydraulic oil are relatively high, and the HL or the HM type hydraulic oil can be selected.
Cause 4
Is the hydraulic system too hot? If the temperature of the hydraulic system is too high, it will have a great influence on the oil, such as the high temperature of the hydraulic oil and the problem that the oil can be blackened in a long time, so it is necessary to carefully check the condition that the hydraulic system is overheated.
Cause 5
If the hydraulic oil is not sufficient, the oil level of the oil will cause the air to be mixed directly, so check the oil pumping line and oil return line, and try to remove the air from the source as much as possible.
Summary
The above is the cause of the failure of the hydraulic oil to become turbid and how to deal with it. It will be introduced here. If a similar fault is encountered in the construction process, it can be checked against the above-mentioned reasons one by one!
