Two common causes of hydraulic cylinder discoloration

Discoloration of non-standard custom hydraulic cylinders is a common situation, the cause and solution of hydraulic cylinder discoloration. The hydraulic cylinder returns to its original tone. Typically, this is pervasive. Hydraulic cylinders tones change every link. at first. It is blue in color, then darkens, turns purple, and turns black. In fact, this is that the discoloration of the hydraulic cylinder itself is not a chemical change, but it is covered with a layer of colorful film, so it looks like the color of the hydraulic cylinder has changed. Firstly, the reasons for the discoloration of the hydraulic cylinder were analyzed.
1. The temperature difference between the internal and external temperature of the hydraulic cylinder is very large
This often happens in winter. When the machine works for a long time, the temperature of the hydraulic transmission system increases, and the temperature of the environmental elements is very low. At this time, the temperature difference between the inside and outside of the hydraulic cylinder is very large. in such cases. The practical operation of the cylinder rod is easy. Hydraulic cylinders change colors.
2. Poor hydraulic oil quality
In order to save the cost of disassembling and replacing hydraulic oil, many small business owners do not choose the original hydraulic oil, which is easy to cause. Hydraulic cylinders change colors. Because hydraulic oil has different proportions in different brands of hydraulic oil additives, it can cause discoloration after mixing. It even caused damage to the hydraulic transmission system.
