Abstract

一种双吸式离心风机，包括有风轮、转轴和外壳，外壳两侧开有对称的进风口，风轮包括有中心盘、叶片和外圆盘，风轮是以中心盘为对称中心的对称结构。该风机与已有的离心式风机相比，风量大、效率高。

Description

双吸式离心风机
本实用新型涉及一种离心式风机。
现有的离心式风机均是单向进风、单向排风，其风轮为单向导风结构，其不足之处是风力较小，风机的利用率低。
本实用新型的目的就是克服上述现有技术的不足，提供一种风力更大、效率更高的双吸式离心风机。
本实用新型的目的可通过如下途径达到：该风机包括有风轮、转轴和外壳。外壳圆筒部设有出风口，转轴通过轴承装于支架上，转轴一端设有皮带轮。其特点是外壳两侧开有对称的进风口，风轮包括有中心盘、叶片和外圆盘。叶片装于外圆盘与中心盘之间，外圆盘为环状，具有一定锥度，便于聚汇风力。叶片与中心盘之间具有一定倾角，且沿中心盘径向呈圆弧形放射状排列。风轮是以中心盘为对称中心的对称结构。中心盘通过法兰盘及螺钉装于转轴上。外壳通过支架固定。通过电机传动皮带轮及转轴，进而带动风轮高速旋转，空气流从两个对称的进风口吸入，经风轮叶片后改变风向从出风口排出。
下面结合附图作进一步说明
图1为本实用新型结构示意图。
图2为风轮沿图1中A—A线的剖视结构图。
外壳2圆筒部设有出风口1，外壳2两侧开有对称的进风口7，转轴9通过轴承10装于支架12上，转轴9的一端装有皮带轮8，叶片11装于中心盘3与外圆盘4之间，中心盘3通过法兰盘5及螺钉6装于转轴9上。
本实用新型与已有的离心式风机相比，风量大、效率高，在风机几何尺寸相同及功率相同的情况下，风量可增大约一倍。
