What seal should be used for the rotary seal ring?
2022-11-23
The rotary seal ring shall be a rotary shaft lip type seal ring of fluorine adhesive. If an O-ring is used, it is recommended to add an elastic pressure to the rotating sealing ring to maintain the contact of the sealing surface, but the effect is not very ideal. Try to use a skeleton to seal. It is recommended to use a mechanical seal. Generally, a bearing is required for rotation. The bearing should be pressed by the bearing cover, and the sealing ring should be installed on the bearing gland. According to the different sealing materials and sealing degree, there are various sealing methods: very common rubber seals, packing seals, mechanical seals and labyrinth seals.

Reasons for failure of rotating seal ring
2022-11-14
The influence of the soft and hard of the rotating sealing ring: In many cases, the function and structure of the product can be completely changed according to the soft and hard of the silicone product. Therefore, in the application process of the rotating sealing ring, due to the selection of different soft and hard, the sealing ring will There are some inevitable problems, such as extrusion gap, excessive stress, too high hardness, product deformation does not rebound, etc.

How to choose the right large size sealing accessories?
2022-11-03
From the point of view of environmental protection, large-size seals must not allow the oil, fuel, harmful liquids and gases and other fluid media inside the machine and system to leak to the surrounding environment. For some petroleum, chemical and atomic energy industries, the leakage rate of large-scale seals should be controlled below 10-7cm3/s. These indicators have been recognized by many countries in the world. However, the sealing of fluid is a complex and difficult problem to solve, the reliability of the seal is not only related to the sealing material and sealing element, but also related to the structure of the connection, the characteristics of the fluid medium, the working conditions and many other factors.

Large size seal: what is the seal?
2022-10-24
According to the manufacturer of large-size seal, the seal indicates tight closure. Sealing can be divided into static sealing and dynamic sealing. Sealing is a component or measure that prevents fluid or solid particles from leaking from adjacent joint surfaces and prevents external impurities such as dust and moisture from invading the interior of the machine equipment. Quiet means that the sealed container is tightly sealed in the sealed compartment in order to seal the seal of the letter and the will.

Performance and Principle of Imported Large Size Sealing Ring
2022-10-14
The performance of imported large-size sealing ring directly affects its sealing effect and service life. The better the performance of the imported large-size sealing ring, the better the sealing effect and the longer the service life. The performance of the sealing ring essentially reflects the strength of its sealing performance. Under standard conditions, the axial or radial compression of the working conditions gives the sealing ring a certain degree of sealing. The performance advantages of high-quality imported large-size sealing rings are mainly manifested from these points:
