What is vacuum： With the technology, we have a certain understanding of vacuum, vacuum technology and vacuum pump. In a given space, the gas state below a atmospheric pressure is called a vacuum state. Compared with the atmospheric state, this particular vacuum state has two basic characteristic...

The two-stage piston vacuum pump series is suitable for suction of air and other general gases. When using air ballast, the pump can suck a small amount of condensable gases (such as water vapor). Additional devices should be used when pumping gases with excessive oxygen content, explosive, corro...

The Molecular Pump of Hybrid Molecular Pump covers almost all possible application fields. The unique design of electromechanical integration has the characteristics of high prestage pressure resistance and is suitable for the vacuum environment of 10-10-10 millibar. The Molecular Pump of Hybrid...

The water ring vacuum unit is mainly operated by roots pump and is made of water ring pump in series. The water ring pump selected by the water ring vacuum unit is more advantageous than other vacuum pumps, because it not only overcomes the limitation of pressure difference when a single water ri...

Dry vacuum pump is a kind of mechanical vacuum pump which can start pumping under atmospheric pressure, and can directly discharge the pumped gas into the atmosphere. There is no oil or other working medium in the pump cavity, and the pump’s limit pressure is equal to or close to that of oi...

Vacuum pump is a kind of rotary variable capacity, vacuum pump must have a front-stage pump with a wide range of pressure can be used to have a greater pumping speed, the extracted gas contains dust and water vapor insensitive widely used in metallurgy, chemical industry, food, electronic coating...

Oil diffusion pump (abbreviated as oil diffusion pump) is a momentum transfer vacuum pump with low pressure and high speed oil vapor as working medium. The pump works in high vacuum area. The oil diffusion pump has the advantages of simple structure, convenient operation and low cost per unit pum...

Rotary vane vacuum pump can set the upper and lower limits of the required vacuum, when the pump reaches the upper limit of vacuum operation will automatically stop, when the vacuum drops to the lower limit when the pump automatically starts. The oil level of rotary vane vacuum pump needs regular...

Vacuum coating technology is an important branch of 2BV liquid ring vacuum pump application technology. It has been widely used in optics, electronics, energy development, physical and chemical instruments, construction machinery, packaging, civil products, appearance science and scientific resea...

Composition of piston vacuum pump: piston vacuum pump is mainly composed of stator, rotor, rotary vane, fixed cover, spring and other parts. The structure uses the rotor which is eccentrically mounted in the stator cavity (the gap between the outer circle of the rotor and the inner surface of the...
