Sealing material properties of the rubber sealing ring of film movement
"With the hardness of the" static ring rubber seal gas film sealing properties of the material [View Details]
Perfluorether characteristic action hydraulic O-ring
Commonly used hydraulic rotary joint stationary ring O-ring materials are manufactured fluorine rubber, nitrile rubber, ethylene propylene rubber, and basically can adapt to the user's requirements, but the medium is 230 ~ 300 ? high temperature HTF environment, these hydraulic O-ring material does not apply, only use perfluoroether hydraulic O-ring. Since Kalrez many models, the use of performance are quite different, so it is necessary to carry out perfluoroether hydraulic O-rings applied research work on the rotary joint. [View Details]
Star rubber seals and working environment parameters
Shenzhen Xu Xinhua Rubber Products Co., Ltd. has strong technical strength and research capabilities to eleven years of unique experience to specific manufacturing rubber products and consistent quality and reliable known to the world, in the market has won wide good credibility. [View Details]
Y hydraulic seal ring
On large construction machinery, Y hydraulic seals are often used in hydraulic or pneumatic cylinder, since only one-way seal, its product structure is provided within the outer lip lip A and B in order to obtain a better initial sealing effect, engineering and technical personnel design products should, in its inner and outer lip leave some amount of interference. After loading work trench, two hydraulic seal lip only, the groove diameter portion in contact with the sliding surface, a certain amount of prestress, sealing function. In operation, the fluid pressure at the sealing lip is deformed in the circumferential direction, completely fit on the surface of the piston rod and the cylinder mating surface, it acts as a seal.

The method of selection using rubber O-rings
Rubber O-ring hardness of choice is more important. Low hardness, easy to install, but prone to peeling, installation damage, extrusion pressure even explode. High hardness, inconvenient to install. [View Details]

Oil-resistant rubber seals during use if the oil medium and long-term exposure, oil can penetrate into the interior to produce rubber swell, resulting in rubber strength and other mechanical properties decrease. Oil rubber can swell, because the oil is infiltrated rubber, produced a molecular interdiffusion, so that a network structure is changed vulcanizates. [View Details]

The ability to recover quickly rubber seals
The rubber is a rubber seal having a reversible deformation of the elastomeric polymer material. Under flexible at room temperature under a small external force can generate a larger deformation force after removal of restitution. This is because the molecular chain can be cross-linked rubber, rubber crosslinked deformed by external force has the ability to recover quickly, and has good physical and mechanical properties and chemical stability. Rubber is rubber industry's basic raw material, widely used in the manufacture of tires, hoses, rubber O-rings, rubber seals and other rubber products. [View Details]
Xinhua Xu rubber hydraulic seal the basics
Rubber hydraulic seals are sealing device for a class of common fundamental element, it plays a very important role in terms of sealing. Rubber hydraulic seals are sealed skills most common type of rubber products. Because the rubber is a polymer material having very elastic, has a wide scope of temperature, giving less stress differences bred medium will have a greater deformation, this deformation can provide the contact pressure, leak compensation gap, to reach the purpose of sealing.

Hydraulic rubber O-rings and practical formula
For the manufacture of a specific product and production process to meet the specific formula designed under laboratory conditions developed formula, the test results are not the end result of hydraulic O-rings, often at the time of production inputs will produce some process difficulties as scorch time is short, poor performance extrusion, rolling sticky roll, which requires performance without changing the basic conditions for further adjustment formula. Hydraulic O-rings in some cases had to take slightly [View Details]
