As a contact seal, the mechanical seal of Roots blower has good sealing effect; as a face seal, it has no wear on the shaft. At the same time, with the help of the sealing material, the self sealing liquid is usually used for long lubrication period. However, the structure is more complex, the ac...

Ceramic filter has been widely used in solid-liquid separation of mining, metallurgy, chemical industry, papermaking, pharmaceutical, coal, food, environmental protection and other industries because of its high vacuum degree, less vacuum loss, significant energy saving, high production capacity,...

Roots vacuum pump is used in pasture to improve efficiency Before, the domestic farm using water ring vacuum pumps and rotary vane vacuum pump. Rotary vane vacuum pump prices are cheap and easy to install, but with high noise, the disadvantage of high oil consumption. Water ring vacuum pump of th...

In recent years, the application of vacuum technology is more and more extensive. The development of clean, efficient, small and economic vacuum components and systems has promoted the application of vacuum pump technology in automation equipment – vacuum adsorption fixture can stably and r...

The impact of the deposits in the incinerator on the engine is also very serious, but it is not an independent assessment target and is usually used in conjunction with IVD. In contrast to the difference in nozzle and intake valve deposits, the use of cleaning agents only increases sediment in th...

In neutral beam injector, the performance of vacuum system has great influence on beam transmission efficiency, service life and safety of related components in the whole beam line. Neutral beam injector (NBI) is a set of equipment that generates high-energy neutral particle beam and transports i...

In pneumatic conveying equipment, pneumatic valve is the key part of the whole operating system, just like people’s cardiovascular system, it has the most important function in the blood night transportation. Roots blower plays such a role in pneumatic conveying and pneumatic conveying equi...

What is the sound insulation cover of Roots blower? It can also be said that Roots fan sound insulation room, as the name implies, can reduce the noise of Roots fan house, our ordinary fan room can not achieve the effect of reducing fan noise, and Roots fan noise enclosure is an effective sound i...

This paper first introduces the lower roots blower. Roots blower is a positive displacement fan which compresses and transports gas by relative movement of two blade shaped rotors in the cylinder. Its main function is gas transportation and pressurization, its main parameters are: flow, head, sha...

The technology of communication satellite has realized the communication between satellite earth stations or between earth stations and spacecrafts, mainly for communication, mobile communications, broadcasting, maritime communications, tracking and data relay. In this critical and demanding appl...
