Reasons for the discoloration of hydraulic piling machine oil
Hydraulic pile driverIn the entire process of use, mechanical failures of varying degrees are usually caused by the force and friction of mechanical parts. As an indispensable substance for the application of pile drivers, abnormalities in hydraulic oil are also particularly widespread. After applying the pile driver for the corresponding time, you will find that the color of the cylinder will change. At first, it will be blue. With time, the color will darken and become blue-purple, or even black.
The discoloration of this kind of oil is actually that the surface of the oil cylinder covers a layer of colored film, and it has no effect on the pile driver and the oil cylinder itself. Today, everyone will briefly talk about the reasons for the change in oil quality of the pile driver.
Everyone can make use of the different color changes, and probably analyze the cause of the color fade. The blue color is caused by the adhesion of the additives in the oil seal and the hydraulic oil to the cylinder rod at high temperature; the blackening is caused by the spray coating in the wear-resistant sleeve It is caused by the lead additive in the material sticking to the cylinder rod at high temperature.
There will be some misunderstandings about the discoloration of hydraulic piling machine oil. If the oil quality becomes black, it means that the lubricating oil has undergone a qualitative change. Nowadays, hydraulic oil has entered a certain variety of additives in order to improve its performance indicators. The lubricating oil for internal combustion engines with detergent and dispersant turns black after being used for a while. It is a normal condition that you should not think that the oil has undergone qualitative changes and replace it lightly. Additives usually make the bearing surface of the pile driver be used in the whole process. Dark in the middle, this is also a normal situation. Therefore, when we judge whether the lubricating oil has undergone qualitative changes, we cannot distinguish by visual effects alone, and we must strengthen comprehensive analysis. In some cases, the oil should be strengthened to inspect and inspect to ensure that the oil is changed according to the quality.
Everyone may have daily maintenance methods, but if you replace the non-hydraulic pile driver special hydraulic oil, it may fade within a few days. This may be due to different brands and different types of hydraulic oils. The quality and performance indicators of extreme pressure anti-wear additives are different.
