Note on installation of oil seal rubber seals
The rubber seal material needs to have the following characteristics [View Details]
How to Select O-ring O-ring hydraulic
Hydraulic pressing the O-ring is applied to the deformation as a percentage of the cross-sectional thickness of the seal in a free state ratio of the amount. Hydraulic cross section deformation of O-ring "power" of the elastomeric matrix like compression spring; the inherent elasticity of the rubber material so that it is pushed back against the mating component. This contact force block of liquids, gases and dry powder to prevent them from between the rubber seal and the hardware of the flow channel. Hydraulic squeeze the O-ring is larger, a greater force is applied to the hardware and tighter seal. But that do [View Details]
The advantageous performance of the silicone rubber o-rings
The way to manufacture the silicone rubber o-rings is to squeeze out the bar-type silicone rubber,then cure by the baking process and cut to be the O shape.Putting the liquid silicone on the connection, sulfide,baking process again to make sure the silicone rubber become O shape. The silicone seal ring using the same materials to connect.According to our experiment,Using the silicone rubber sealing ring we�ve invented will ensure to make the hardness better than others especially the connection.In this way to manufacture the silicone o-ring obviously make the method low cost,high efficiency and high quality.

Effect of materials on the performance of oil seal hydraulic seals
The leakage of lubricating oil from bearing. Requirements on the seal hydraulic seal is size (inner diameter, outer diameter and thickness) should be in accordance with the provisions; requires appropriate flexibility that the shaft can be properly stuck and plays a role in sealing; It would be heat-resistant, wear resistance, strength, good resistance to medium (such as oil or water), and long service life.

Hydraulic seals static seals and dynamic seals distinguish
Hydraulic seals Static seals: according to the working pressure, static seal can be divided into low-pressure and high-pressure static sealing static sealing. Hydraulic seals commonly used in low-voltage static sealing material is relatively soft, wide gaskets gasket, high pressure static sealing material is hard, the contact width is very narrow metal gasket. Hydraulic seals Dynamic Seals: Seals by its relative movement of the zero member is in contact, can be divided into contact and non-contact seal seal. Generally contact seal sealing, but by friction, wear limits apply to the lower surface of the seal line of the occasion. In the contact seal in the contact position by the seal can be divided into the [View Details]
Xinhua Xu rubber goods and materials performance analysis
Rubber is one of the important basis for the national economy of the traditional industries, product variety, widely used in industrial fields transportation, aerospace, machinery and electronics. In addition, many rubber products can be directly used as the final product aspects of daily life, sports activities and health care and so on. Rubber products industry has been rapid development, market demand is relatively strong, industrial structure adjustment, which yield a variety of products has been ranked first in the world.

Hydraulic o-ring seal
Hydraulic O-ring is mainly used for static seals and reciprocating seals. Seal for rotary motion, the sealing device is limited to low-speed reverse. Hydraulic O-ring on the peripheral device or ordinary inner circle within the rectangular cross-section groove seal [View Details]
Factors affect rubber seals
Vulcanized rubber seals is through chemical cross-linking between rubber molecules will be substantially converted to plastic raw rubber elastic and dimensionally stable product, the physical properties of vulcanized rubber stable, extended temperature range. "Vulcanization (Curing)" the term commonly used throughout the rubber industry, plays an important role in rubber chemistry. Vulcanized rubber molecular chains (crosslinking) reaction capacity depends on its structure. Unsaturated diene rubber (e.g. [View Details]
Rubber O-ring leak analysis
We introduced the rubber O-ring which is divided into several cases, but the problems we encounter these relief how to do Here we have to analyze. Manufacturing and assembly factors: All hydraulic components and rubber O-ring seal member have strict dimensional tolerances, surface treatment, surface finish and geometric tolerance requirements. If the difference in the manufacturing process Super League, for example: the radius of the cylinder piston seal groove depth or width, put a ring of pore size tolerance or because of processing problems caused by the loss of a circle, so that the part itself has a congenital leakage point, leakage after assembly or during use.

Introduction to various types of rubber seals
Lip Lip rubber seal ring type a lot, as shown in FIG V-shaped, shaped, L-shaped, Y-shaped, and the like. V-shaped ring rubber lip seal it is secret A: A typical form of rings, lip seals is the oldest and widely used applications. Reciprocating portion generally used for hydraulic, pneumatic and hydraulic machines, working pressure up to 30MPa, cloth rubber V-ring of up to 60MPa, operating temperature up to [View Details]
