Selection and use of large size seals
2022-09-26
O-ring seals are typically squeeze seals. The compression ratio and tension of large seal section diameter are the main contents of seal design, which are of great significance to seal performance and service life. Large size seal is generally installed in the sealing groove for sealing. The good sealing effect of the large-size seal depends to a large extent on the correct matching of the size of the large-size seal with the size of the groove to form a reasonable amount of compression and tension of the sealing ring. In the design and processing of the sealing device, if the compression of the large-size seal is too small, it will cause leakage; if the compression is too large, the rubber stress of the large-size seal ring will relax and lead

Installation Precautions for Large Size Seal
2022-09-14
The installation quality of large size seal has an important influence on its sealing performance and service life. Leakage problems are usually caused by improper installation. The large-size seal shall not be scratched, installed in incorrect position or twisted during installation. The sealing groove and sealing mating surface must be strictly cleaned before assembly, and the large-size sealing surface should be coated with grease during assembly.

The selection of large-size seal compression rate W should consider the use conditions, static seal or dynamic seal; static seal can be divided into radial seal and axial seal; radial seal (or cylindrical static seal) leakage gap is radial gap, axial seal (or flat static seal) leakage gap is axial gap. According to the pressure medium acting on the inner or outer diameter of the large-size seal, the axial seal is divided into two cases: internal pressure and external pressure. The internal pressure increases and the external pressure decreases the initial stretch of the large gauge seal. For the above-mentioned different forms of static seals, the sealing medium has different directions for large-size seals, so the preloading design is also different. For dynamic dense

The self-sealing compression seal specifications commonly used in large-size seals include O-rings, square seals, etc. The temperature is suitable for various sealing occasions. Large-size seals have simple structure, easy design and operation, and low sealing material cost. It has many advantages and is the best choice for ordinary customers who do not require high sealing materials. O-rings are dynamic and static sealing components used in many hydraulic transmission systems. It is installed in the seal groove and is deformed by the radial compression of the friction of the mechanical movement, which generates contact stress on the higher surface of the seal, forming a leakage condition to prevent unpressurized liquid.
