一种同轴双风机冷却塔

本发明公开一种低噪声同轴双叶轮冷却塔轴流风机,包括支承风筒、一级叶轮组件、动力系统支承底架、减振器、减振平台、皮带减速箱组件、导流风筒组件、上风筒和二级叶轮组件。通过用同一动力系统配置一级叶轮+导流器+二级叶轮结构形式的1.5级双叶轮轴流风机,在满足配套的冷却塔所需通风量和克服通风阻力所需静压的条件下,叶轮叶片和导流器叶片的旋绕速度在径向均采用线性分布流型的叶栅设计方法,大幅度降低风机工作叶轮外园圆周速度,相应加大叶轮的叶片弦长或叶片数量、叶片安装角措施来实现冷却塔1.5级双叶轮轴流风机。与单叶轮级轴流风机相比,在相同通风量和风机静压下主动降噪,获得低噪声的排放效果。

该风机被用在超静音冷却塔配置上,风机为铝合金设计,航空级铝合金叶片,轮毂采用金属模成型,叶片用不锈钢U型码连接,无级调节风机角度,表面喷涂防腐处理,具有全压高、风量大等优点。而且其气动性能好、高强度、耐腐蚀,并可通过改变叶片安放角度方法满足工艺要求及提高装置效率。该风机最大的特点是突破传统冷却塔的4片、6片或者8片风叶,该技术为国家发明专利,在一台冷却塔上安装多层多片风叶,常规配置为21片超静音风叶,保证风量满足的情况下达到降低噪音的效果;
