The principle of negative pressure conveying of Roots vacuum pump
##Introduction
Roots vacuum pump is a widely used vacuum equipment in the industrial field, and its unique negative pressure conveying ability makes it play an important role in multiple industries. This article will delve into the principle, application scenarios, and importance of Roots vacuum pump negative pressure conveying in industrial production.
##Working principle of Roots vacuum pump
The working principle of Roots vacuum pump is based on two interlocked rotors rotating inside the pump chamber, generating negative pressure by changing the volume of the pump chamber. When the rotor rotates, the volume of the pump chamber gradually increases, forming negative pressure and thus sucking in gas. As the rotor continues to rotate, the volume of the pump chamber decreases, and the gas is compressed and discharged outside the pump. This continuous process of gas suction and discharge enables the Roots vacuum pump to continuously generate negative pressure.
##The concept of negative pressure delivery
Negative pressure conveying refers to the process of using negative pressure to transport materials from one place to another. In Roots vacuum pumps, negative pressure conveying is the process of drawing gas or material into the pump through the negative pressure generated by the pump, and then transporting it to the destination through pipelines. This conveying method has advantages such as energy saving and environmental protection, and is widely used in industries such as chemical, food, and pharmaceutical.
