advantage:
1. Simple structure, integrated groove design, reduce processing and design costs;
2. Compact structure, small parts appearance;
3. Simple installation, reduce risk;
4 can be applied to a variety of sealing problems, such as: static seal, dynamic seal, single-acting and double-acting seal;
5. Wide choice of materials, suitable for most fluids;
6. Large volume of shipments, complete specifications, easy maintenance and repair.
application:
O-rings can be used both as sealing elements and as force-applying elements for hydraulic sliding seals and wiper rings, and are therefore widely used in various fields. It can be said that in the industrial field, whether it is a single seal used for maintenance and maintenance, or applications requiring quality assurance such as aerospace, automobile industry and general industry, there is no use of O-rings.
1. O-rings dominate in static sealing applications;
2. Used as a radial static seal, for example: for shaft sleeves, seal covers, pipes, seals for cylinders;
3. Used as an axial static seal, for example: for flanges, flat plates and end caps, etc.;
4. For dynamic applications, O-rings are only recommended for medium load conditions;
Due to speed and pressure limitations, O-rings are generally used to:
1. Under low load conditions, the reciprocating piston, piston rod and plunger seal;
2. Sealing when working with low rotation or spiral movement on shafts, spindles and rotary power input shafts.
