Problems solved by technology

Under this structure, if the volute fan fails and needs to be repaired and replaced, the volute 94 must be removed first, and then the motor 91 and the impeller 93 are removed from the mounting plate 92. If the motor 91 is fixed on the installation Behind the plate 92, if the motor 91 needs to be inspected, the mounting plate 92 needs to be removed. The process is very complicated and the maintainability is poor.

Embodiment 2

[0083] Example two such as figure 2 As shown, it involves a volute fan installation structure, which is suitable for the volute structures of structure 2 and structure 3. The volute fan installation structure of embodiment 2 will be described by taking structure 3 as an example. For the volute structure of structure 2 That is to say, the application on the volute structure of structure 2 can be realized only by canceling the volute bottom plate 842 in structure 3. Specifically, the volute fan installation structure includes a volute 84 , an impeller 83 , a motor 81 and a mounting plate 82 . The volute 84, which is used to accommodate the impeller 83, includes at least one side wall and a peripheral wall surrounding the impeller, and is formed into a cylindrical shape whose radius relative to the axis of the motor increases along the direction of rotation of the impeller 83, the inside of the volute 84 An air supply passage is formed, which extends in a tangential direction f...

Abstract

The invention aims to provide a volute fan mounting structure convenient to mount and maintain, mainly solving the problem of poor maintainability of the volute fan mounting structure in the prior art. The volute fan mounting structure comprises a volute fan and a mounting plate, wherein the volute fan comprises a volute, a motor and a vane wheel; the motor is mounted on the volute; the volute is fixed to the mounting plate; a mounting plate air inlet is formed in the mounting plate; an air inlet of the volute is opposite to the air inlet of the mounting plate. The volute fan mounting structure is relatively convenient to mount and maintain. The invention also provides an assembling method of the volute fan mounting structure.

Description

technical field [0001] The invention relates to the field of air supply mechanisms, in particular to a volute fan installation structure and an assembly method thereof. Background technique [0002] Volute fans currently on the market, such as figure 1 As shown, it includes a motor 91, a mounting plate 92, an impeller 93, and a volute 94. The volute 94 is integrally formed. The motor 91 is installed on one side of the mounting plate 92, and the impeller 93 and the volute 94 are installed on the other side of the mounting plate. The motor shaft passes through the mounting plate 92 and is connected with the impeller 93 to drive the impeller 93 to rotate. The side of the volute 94 close to the mounting plate 92 is open, and the side away from the mounting plate 92 forms an air suction port. The volute is sleeved on the impeller 93 The outside and together with the mounting plate 92 form a space for accommodating the impeller 93 . The installation steps of this structure are a...
