Rubber Rings Factory introduced that the sealing ring is mainly used for sealing of centrifugal pumps, centrifugal compressors, engines, etc. The sealing ring is not sensitive to the running state of the machine, and has stable sealing performance; the sealing ring does not produce wear, the sealing is reliable, and the maintenance is simple. , Convenient maintenance, the seal ring has a simple specification and structure, with only a few simple rings, pins, springs, and other parts. The material of the seal ring is metal, which is solid and resistant to high temperatures; because the sealing gap is a liquid film, the friction power is small, so we are using it There will be higher efficiency after the machine.
The sealing ring can be composed of a multi-layer floating ring, which can effectively seal the high pressure above 10MPa; the high-speed fluid mechanical process can be between 10000 and 20000r/min, and the speed can be as high as 100m/s. The sealing ring is made of corrosion-resistant metal materials or graphite materials. , Can be used for sealing of strong corrosive media. The sealing ring is not sensitive to the running state of the machine and has stable sealing performance. The seal ring is a non-contact seal with long service life and high reliability. The friction force of the liquid film in the gap of the seal ring is very small, which makes the machine more efficient.
The surface hardness of the seal ring is required to be relatively high. When it is made, the hardness can improve the wear resistance. In order to achieve the hardness of the surface, the overall quenching and hardening treatment is required, but the quenching and hardening will cause the metal to be damaged and deformed. Nitriding, laser quenching, and other various treatments to harden the surface, these methods can reduce the amount of deformation of the metal ring compared with the overall quenching. If the surface roughness of the seal ring is very large, the degree of wear will increase, and the wear resistance will be weakened.
Under the condition of boundary lubrication, there can be enough space to store lubricating oil, which can reduce friction and prolong the service life. The sealing ring is a workpiece with high precision requirements. When using it, it is necessary to extend the service life of the original as much as possible. If the part is replaced in the middle, it is easy to cause the problem of inappropriate matching and affect the use. During the installation process, the sealing ring is not installed correctly and is offset, and it is not installed in place. This will cause the pressure on the sealing surface to be different, resulting in oil leakage.
