Abstract

The invention discloses an airtight miniature Roots blower with a water pump. The airtight miniature Roots blower comprises a shell A, a fan driving rotor shaft and a fan driven rotor shaft are installed in the shell A in parallel, one side of the shell A is connected to a gear cavity, a gear transmission system is arranged in the gear cavity and is respectively connected to the fan driving rotor shaft and the fan driven rotor shaft, a bearing transmission mechanism A is installed on the fan driving rotor shaft and the fan driven rotor shaft, the other side of the shell A is connected to a fan rear bearing chamber, a bearing transmission mechanism B is arranged in the fan rear bearing chamber, the bearing transmission mechanism B is connected to the fan driving rotor shaft and the fan driven rotor shaft, two opposite sides of the shell A are respectively provided with a fan air inlet and a fan air outlet and the fan air inlet and the fan air outlet are communicated with the interior of the shell A. The airtight miniature Roots blower solves the problem that the existing Roots blower has poor sealing performances or a short sealing element life and realizes two pump purposes.

Description

technical field [0001] The invention belongs to the technical field of fan equipment and relates to an airtight small Roots fan equipment with a water pump. Background technique [0002] Roots blower is a common volumetric blower, which is widely used in sewage treatment, pneumatic conveying and vacuum applications. However, common Roots blowers generally have the following deficiencies: First, the seal between the pump chamber of the Roots blower and the environment The isolation performance is poor, or after the sealing and isolation performance is improved, the problems of short life of the seal and frequent maintenance operations cannot be avoided; second, the mechanical heat generated during the operation of the fan depends on air cooling, and the heat cannot be recycled, resulting in waste of system energy. Contents of the invention [0003] The purpose of the present invention is to provide an airtight small Roots fan equipment with a water pump, which solves the pr...
