Do You Know O-Ring Seals?
-
O-Rings Seal is a rubber ring with a circular cross-section and is called an O-ring because of its O-shaped cross-section. It is also known as an O-shaped circle. It began to appear in the mid-19th century when it was used as a sealing element for steam engine cylinders. It is one of the most widely used hydraulic and pneumatic transmission systems. Usually, in Taiwan companies, Japanese companies are called O-Ring.
The O-ring seal is referred to as the O-ring, which is a rubber ring with a circular cross-section. O-rings are the most widely used seals in hydraulic and pneumatic systems. The O-ring has good sealing performance and can be used for static sealing or dynamic sealing; it can not only be used alone but also is a basic component of many combined sealing devices. It is widely used. If the material is selected properly, it can meet the requirements of various media and motion conditions.
O-rings are widely used in various hydraulic and pneumatic components, pipe joints, cylinder surfaces and flange surfaces. For the O-ring used during the movement, when the working pressure is greater than 9.8Mpa, if the pressure is one-way, set the retaining ring on the other side of the pressure direction of the O-ring; if the pressure is two-way, place it on both sides of the O-ring a retaining ring. To reduce friction, wedge-shaped retaining rings can also be used. When the pressure liquid is applied from the left side, the right retaining ring is pushed up and the left retaining ring is not in contact with the sealing surface, so the friction force is reduced. Generally speaking, the use of retaining rings will increase the friction of the sealing device, and the wedge-shaped retaining ring is important to reduce this friction. For the fixed ring, when the working pressure is greater than 32Mpa, a retaining ring is also required.
