Hydraulic oil is used as the power transmission carrier of the hydraulic system, and at the same time takes into account a certain lubricating effect. Therefore, the cleanliness and performance parameters of hydraulic oil directly affect the use of hydraulic parts, which in turn affects the working performance of the equipment.
How to deal with the turbid hydraulic oil? Many owners have encountered that the hydraulic oil becomes cloudy, and the impurities in the hydraulic oil are difficult to clean. The following will introduce this problem in detail.
Reason 1 Water mixed in hydraulic oil is the primary reason for oil becoming turbid. You can do a small test, drop a few drops of hydraulic oil on a hot steel plate, and check whether there is foam to determine whether there is water in the oil. If bubbles are clearly observed, it can be determined that the hydraulic oil contains moisture. If the oil is new and the replacement time is not long, let the oil settle to the bottom and let the water settle to the bottom. If it is close to the oil replacement time, the oil can be replaced directly. Reason 2 Air is mixed into the hydraulic oil. First of all, if air is mixed into the hydraulic oil, it will appear white and turbid. At this time, the owner should focus on checking whether there is air leakage in the hydraulic pipeline, and cut off the possibility of air entering from the root. Reason 3 Do you mix hydraulic oil? Strictly speaking, hydraulic oils of different labels and brands cannot be mixed, especially hydraulic oils with uneven prices, which are likely to cause the oil to become turbid after mixing, which will cause damage to hydraulic components. damage. When selecting hydraulic oil, the variety of hydraulic oil must be selected according to the working environment and working conditions. When selecting hydraulic oil, it must be comprehensive from many aspects such as working pressure, temperature, environment, structure and material of hydraulic system and parts, and economy. consider. When the working pressure is relatively high, the requirements for the lubricity and anti-wear properties of the hydraulic oil are relatively high, and HL or HM type hydraulic oil can be selected. Reason 4 Is the hydraulic system overheated? If the temperature of the hydraulic system is too high, it will inevitably have a great impact on the oil. For example, if the temperature of the hydraulic oil is high, the oil will turn black after a long time. Therefore, the owner should also carefully check the hydraulic There is an overheating condition in the system. Reason 5 Insufficient hydraulic oil and insufficient oil level will directly lead to air mixing, so check the oil pumping line and oil return line, and try to eliminate the source of air entering. Summarize The above is the cause of the failure of the hydraulic oil to become cloudy and the treatment method. I will introduce it to you here. If you encounter similar failures during the construction process, you can check and repair them one by one according to the above reasons!
