The Atlas vacuum pump is a device that sucks the gas out of the equipment, so that the pressure in the equipment is less than one atmosphere。In fact, Atlas vacuum pump is a gas conveying machine, which transports gas from an environment below atmospheric pressure to the atmosphere or the same environment as atmospheric pressure。So what are the types of Atlas vacuum pumps?
First, according to the Atlas vacuum pump structure classification
1. Mechanical type。This kind of vacuum pump is similar to the compressor, which belongs to the reciprocating and rotating structure of the volumetric type, and the turbomolecular pump of the dynamic type, which belong to the extraction vacuum pump。2. Jet pump。There are two forms of injection pump and diffusion pump, and the booster pump that combines the two is also a suction vacuum pump。
3. Suction。Relying on physical or chemical methods to make the gas molecules suck on the surface of the pump wall, it belongs to the trap vacuum pump。
Two, according to the working principle of Atlas vacuum pump classification
1, extraction, vacuum pump suction system gas, and gas molecules to the system outside。
2. Trap type。The vacuum pump captures the gas molecules in the system and directly adsorbs on the pump working wall without discharging the system。
Three, according to the work function of Atlas vacuum pump in the system classification
1. Main air pump。The main working pump to achieve the required pressure。
2, pre-pumping pump。When the main pump cannot start pumping directly in the atmospheric state, the pre-pumping pump must be pumped to a certain pressure before the main pump can enter the work。
3, the front pump。When the main pump cannot directly discharge the pumped gas into the atmosphere, it needs to be connected to the front pump in series。
4, maintain the pump。When the main pump completes the required pressure stop work, due to system leakage or surface evaporation and other reasons, the pressure may rise, so the maintenance pump continues to pump。
