Shaft Seals

Pump with a wide range of mechanical seals, different models, but there are five major leaks: Seal between sleeve and shaft; seal between movable ring and shaft sleeve; dynamic and static ring seal; t...

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...

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...

Mechanical seal is a common shaft seal device, for example, reaction kettle, compressor, centrifugal pump, centrifuge and so on are all shaft seal devices. These devices have been widely applied in ma...

For the newly built large and medium-sized hydropower stations, the water turbine generator units are required to carry out central control, which can complete the start-up, parallel network or shutdo...

It can prevent high-pressure liquid from leaking out of the pump and prevent air from entering the pump. Although the shaft seal in the pump doesn’t occupy a lot of space, whether or not the pump can...

The pressurized water reactor is one of the light water reactors. According to statistics, about 60% of the world's nuclear power plants use pressurized water reactor, which uses pressurized boron con...

The seal between the rotating pump shaft and the fixed pump housing is called the shaft seal. Its function is to prevent the high-pressure liquid from leaking out from the pump along the shaft, or the...

We make a comparative analysis of the structure and sealing principle of the main shaft. The main shaft structure of the common grinding and polishing machine has a certain sealing performance. When t...

Because the main pump shaft seal is the consumption piece, a large number of spare parts are needed in the life period of the power plant. Considering the occupancy rate of the static pressure shaft s...

When researching applied sealing, theoretical analysis and calculation have been carried out repeatedly to form a calculation program, and the result is that this program conforms to the calculation r...

In recent years, our country's economy continues to develop steadily, and at the same time, the demand for power supply is increasing continuously, and now the main channel of power production is the ...
