Pump Seals

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...

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...

In the case of materials, bellows are made of nickel chromium stainless steel, nickel chromium molybdenum alloy and high nickel alloy steel. It has the advantages of high hardness, high strength, high...

Mechanical seal is also known as end face seal. Mechanical seal belongs to packless seal. It can be fixed on the shaft and pump, and there are two sections to ensure close proximity to the sealing pos...

In the 90s of last century, Lanzhou petrochemical company undertook a major national equipment and technology research project--"the research and development technology of the dilute sulphuric acid pu...

Mechanical seal is the key component in the power plant of chemical enterprises. Its life and reliability determine the installation level of large compressors and pumps. Therefore, in order to meet t...

Through long-term improvement practice and innovative design, we find that, during the design of the main shaft of machine tool, adopting good main shaft sealing structure can not only improve the sea...

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...

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...

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...
