You should also know that many machines are made up of parts. If these parts are missing, then there is no way to complete the assembly of the machine. Having said that, there are only a few key parts of some machines. The machine lacks other less important parts and can still run, but once the key parts are confirmed, they can't run. So what are the parts that cannot be separated from the long arm of the excavator?

In fact, the parts that cannot be separated from the long arm of the excavator are also inseparable from many construction machinery and equipment. That is, hydraulic cylinders, and good hydraulic cylinders need seals. So today Huitong Heavy Industry will talk about the extension Types and methods of non-open parts and seals.

Generally, the long arm of the excavator used by people is the seal ring, also called the skeleton seal, which can block the hydraulic oil and prevent the hydraulic oil from leaking. So what are the sealing rings that are widely used in hydraulic cylinders? There are the following types: dustproof ring, cylinder sealing ring, buffer sealing ring, guiding support ring, end cover sealing ring and cylinder sealing ring.

What are the different functions of the different sealing rings in the long arm of the excavator? The dust ring can prevent external air pollutants from entering the hydraulic cylinder. There are two ways to install this dust ring, one is the O snap-in type and the press-in type. The more commonly used method is the snap-in type, because it requires The natural environment is not so strict, and it is more suitable for people's use environment. The oil seal ring is generally installed on the inner side of the hydraulic cylinder end cover to block the leakage of gear oil. It has different effects when applied with different support rings. You can choose according to your needs.
