I’ve never seen this type of vacuum pump; could someone with expertise explain it to me?

What is the structure of this pump?
This post was last edited by altpage on 2017-1-16 at 16:11. The claw-type vacuum pump consists of multiple stages of rotors, with each stage containing 2 rotors. These two rotors rotate in opposite directions; the suction port is connected to the pump chamber, and as the volume of the pump chamber increases, air is drawn in. When the rotors close off the suction port, suction stops. Subsequently, the volume of the pump chamber decreases, compressing the gas. When the exhaust port opens, the gas is discharged from the pump chamber, and once the exhaust port is closed, discharge is complete. This process repeats continuously. It has high requirements for medium cleanliness and is very useful.
Cradle pump, I believe many people are familiar with this
This is a claw-type vacuum pump with multi-stage rotors. This manufacturer also came to our company to give a presentation; they said that the equipment originally developed by their research institute for simulating vacuum environments in missiles is now available for civilian use, as the relevant technology has been made accessible to the public. It can be said that they have strong R&D capabilities and should handle after-sales issues well; however, the corrosion problem is a serious issue. The factory staff were also very honest, which is why we didn’t make the purchase
