The utility model has the advantages of convenient installation and maintenance, the use of single fan inlet are arranged in parallel with the effect of doubling the amount of wind, and can replace the traditional impeller into bilateral fan, small occupied space, transmission mode, if one fan stopped or damaged, will not lead to overall the failure of the device, wide application range.
【技术实现步骤摘要】
离心风机
本技术涉及通风设备,具体涉及一种离心风机。
技术介绍
目前,国内外的离心通风机主要有两种形式:单叶轮单侧进风、共用中盘的双叶轮双侧进风。单叶轮单侧进风风机,在管道空间有限但要求大风量时,在满足风量要求时,其安装规格要求很大,特别是在高度上;双叶轮双侧进风风机只能是皮带传动(E式)、联轴器传动(F式),传动方式少,且这两种传动方式都需占用较大的空间,在空间受限时是很大的难题;同时由于风机的进风口布置在两侧,在进风口加装进风管道时结构非常复杂。
技术实现思路
本技术所要解决的技术问题是提供一种风量大,传动方式多,占用空间小的离心风机。实现本技术目的的技术解决方案为:离心风机,其特征在于:包括驱动机构、风机壳体和若干个叶轮,所述叶轮与驱动机构联接,所述风机壳体包括若干个气流加压腔,气流加压腔并列设置在风机壳体中且互不连通,每一叶轮对应一气流加压腔,每一气流加压腔均独立设有进风口和出风口。所有出风口上设有把所有出风口合并成只有一个接口对外连接的出风集风管。所述驱动机构为若干台电机,每一叶轮对应一电机。所述驱动机构为一台以上电机,所述电机通过皮带或联轴器与叶轮传动。所述进 ...
