How to classify and work the vacuum roots pump used in vacuum plasma cleaning equipment:
The vacuum pump set of the low-pressure vacuum plasma cleaning equipment introduced by Chengfeng Zhizhi before, we mentioned that the Roots-Type Vacuum Pump is the secondary pump that forms the oil and dry vacuum pump sets. How to classify Roots pumps? How does it work?
Roots vacuum pump is a vacuum pump designed based on the principle invented by the Roots brothers in the United States. For some large-cavity vacuum plasma cleaning equipment with high vacuum requirements or high vacuum speed requirements, we often install Roots vacuum pumps on the vacuum system. Well, today we will introduce the classification and working principle of commonly used Roots vacuum pumps.
The composition and working principle of the Roots vacuum pump:
Roots vacuum pumps are variable-capacity vacuum pumps, and the pumping speed is proportional to the rotation speed. The pump chamber of the Roots vacuum pump is equipped with two "8" shaped rotors, which are installed on a pair of parallel shafts, and the two rotors are perpendicular to each other, driven by a pair of gears with a transmission ratio of 1. , Carry out mutually opposite synchronous rotation movement. There is still a certain gap between the rotor and the rotor, and between the rotor and the inner wall of the pump casing, which can realize high-speed operation. Therefore, Roots vacuum pumps rely on this kind of synchronous and reverse rotation of the rotor to inhale gas from the air inlet, enter the space between the rotor and the pump casing, and then discharge through the exhaust pipe to achieve vacuum.

Classification of Roots vacuum pumps for vacuum plasma cleaning equipment:
The pump is divided into three categories by the positions where the two rotors are placed in the pump body:
Vertical Roots vacuum pump: The axes of the two rotors of the Roots vacuum pump are arranged horizontally, but the plane formed by the axes of the two rotors is perpendicular to the horizontal plane;
Horizontal Roots vacuum pump: The axes of the two rotors of the Roots vacuum pump are arranged horizontally, and the axes of the two rotors form a plane and are arranged horizontally;
Vertical-axis Roots vacuum pump: The two rotor shafts of the Roots vacuum pump are installed perpendicular to the horizontal plane.
The above is the working principle and classification of the roots vacuum pump used in the low-pressure vacuum plasma cleaning equipment.
