Novel Roots blower

Abstract

The invention discloses a novel Roots blower. The novel Roots blower comprises a Roots blower main body, and is characterized in that the Roots blower main body is connected with a permanent magnet synchronous motor through an integrated direct connection structure; the permanent magnet synchronous motor is not provided with a bearing; an inlet silencer is arranged at the upper end of the Roots blower main body; a safety valve connected through a check valve is arranged on the side edge of the Roots blower main body; an outlet silencer is arranged on the safety valve; and the outlet silencer is provided with a shockproof joint. A permanent magnet motor rotor is directly connected with a rotor of the Roots blower main body in a shaft extension mode, a flange of the Roots blower main body can be used as a front cover of the motor, a back cover can be directly simplified into a thin iron plate, a front bearing, a rear bearing, a front end cover and a rear end cover are omitted simultaneously, the cost is reduced, and the structure is simplified.

Description

technical field [0001] The invention relates to a novel Roots blower. Background technique [0002] At present, most of the Roots blowers on the Chinese market use conventional asynchronous motors (such as attached figure 1 As shown), the Roots blower head 1 drives the transmission work of the belt 3 and the pulley through the asynchronous motor 2. Usually, a protective cover 4 is installed at the place of the belt and the pulley, which is large in size, low in efficiency, large in energy consumption, and high in failure rate , requires frequent maintenance; the motor will generate a lot of heat when it is running, and the motors currently on the market cannot continuously and constantly dissipate heat for the motor. Contents of the invention [0003] The purpose of the present invention is to provide a novel Roots blower to solve the problems in the prior art. [0004] The technical problem solved by the present invention can adopt following technical scheme to realize:...
