Mechanical Seals

1. The influence of the seal surface state on the leakageIn order to explain completely a sealed surface, there must be five parameters: roughness, flatness, wave degree, knife mark state and disconti...

In the research in the last century, there were obvious wear and local burning phenomena on the mechanical seal friction pairs of the rotating seals in the measurement of the characteristics of the ro...

The ring type rotary seal device is mainly applied to the dynamic seal of the rotating shaft. For example, the seal between the connecting disc on the clutch and the stationary bearing seat. The steer...

The resurfacing welding is to use the welding method to melt the metal on the tool or machine parts. The commonly used surfacing technology is cold resurfacing welding, electroslag resurfacing weldin...

The nominal contact area between the effective area and the sealing surface under mechanical seal fluid pressure is called mechanical seal area ratio and was known as equilibrium ratio on abroad. Equi...

Seal is to prevent the leakage of fluid or solid particles from the adjacent joint surface and to prevent the external impurities such as dust or moisture invade the internal parts of the machine equi...

China's rotary seal industry started in 1960s. Although some enterprises have formed a certain scale through many years of technological transformation, technology introduction, joint venture and join...

Zero leakage seal is the permanent pursuit of chemical equipment, it is this requirement that has promoted the application of magnetic pump and shield pump. However, there is still a long way to go to...

The key and difficult point of the wear-resistant rotary sealing valve is the sealing of the valve. In order to meet the requirements of the sealing VI level, the roughness of the sealing surface is r...

Coke dry quenching is a kind of coke quenching method using inert gas to cool the red coke. During the dry quenching process, the red coke is loaded from the top of the coke dry quenching furnace. The...
