Many users think that the hydraulic cylinder discoloration of the hydraulic cylinder manufacturer is a quality problem of the cylinder, and they are often very anxious. In fact, the cylinder discoloration of the hydraulic cylinder manufacturer is a very common phenomenon. So what's the reason? Let's introduce the causes and solutions of this phenomenon in detail:
One: The reasons for the discoloration of the hydraulic cylinder are as follows:
1, the hydraulic system has high temperature phenomenon. The piston rod is often in contact with the low temperature environment at high temperature resulting in discoloration.
2. During the maintenance of the hydraulic cylinder by the hydraulic cylinder manufacturer, the special hydraulic oil not of the brand was replaced. The hydraulic oil contains an extreme pressure anti-wear additive, which changes color depending on its quality and performance.
3, the blue is caused by the additives in the oil seal and hydraulic oil attached to the hydraulic cylinder rod at high temperature, and the black is caused by the lead additives in the spray material in the wear-resistant sleeve attached to the cylinder rod at high temperature.
Two: Solution:
1, if the hydraulic cylinder manufacturer's hydraulic cylinder appears a small blue part, you can ignore it, after a period of time will automatically disappear;
2, if the discoloration is serious, should replace the oil seal and wear sleeve, and try to avoid the hydraulic oil temperature is too high, the hydraulic oil will return to normal after a period of time.
It can be seen that the main reason for the discoloration of hydraulic cylinder manufacturers is improper use. Therefore, in order to avoid this phenomenon, we should pay attention to the above points in daily use.
