Researchers found that most of the two-way rotary groove lines limit the load capacity of the gas film, resulting in the small end face clearance and high temperature. The pressure fluctuation or roto...

The performance of the sealing material used in rotary seal valve is the key to determine the sealing and service life of the rotary feed valve. The temperature range of the rotary valve is very large...

Mechanical face seal is a kind of main shaft sealing form, which makes use of spring or other elastic material to form a thin layer of liquid film between the end face of the main shaft seal. The mech...

Rotary seal is widely used in rotatingliquid supply system. Its sealing forms include radial seal and end seal. Interms of end seal, there are balance, partial balance and non-balance types.These seal...

For the normal contact mechanical seal, the wear of the end face is one of the main causes of failure. The wear rate of the end face has an important influence on the life of the mechanical seal. At p...

The pipeline system with hard erosion medium will wear the valve and pipe strongly. In order to enhance the service life of the equipment, a layer of wear-resistant material is usually added to the in...
