Background

Roots blower belongs to positive displacement blower, and has impeller end face and front and back end covers. The principle is a rotary compressor which compresses and delivers gas by means of the relative movement of two lobed rotors in a cylinder. The blower has simple structure and convenient manufacture, is widely applied to oxygenation, sewage treatment aeration and cement transportation, is more suitable for a gas transportation and pressurization system in low-pressure occasions, and can also be used as a vacuum pump and the like;

the Roots blower is one kind of positive displacement blower, and has two three-blade impellers rotating relatively in the sealed space with casing and wall board, and because each impeller adopts involute or epicycloidal envelope, the three blades of each impeller are identical, and the two impellers are identical, this greatly reduces the machining difficulty. The impeller adopts numerical control equipment during processing, so that a certain minimum gap can be kept no matter what position the two impellers rotate to under the condition that the center distance is unchanged, and therefore leakage of gas is ensured within an allowable range.

In view of this, we propose a Roots blower with a port seal structure.
