摘要： A furnace distribution blower for use in a conventional furnace that is configured without a blower housing. The furnace distribution blower includes a backward curved impeller mounted around a drive motor having a central drive shaft. The drive motor rotates the backward curved impeller to draw air into the inlet of the impeller. Preferably, the inlet of the impeller is closely mounted to an inlet bell of the furnace. The furnace distribution blower can be mounted to a support tray such that the furnace distribution blower can be moved from an operating position in which the impeller is positioned beneath the heat exchanger and a service position in which the impeller is removed from within the furnace housing. The elimination of the blower housing decreases the cost of the furnace distribution blower as compared to a blower having a housing.
摘要翻译：一种在没有鼓风机壳体构造的常规炉中使用的炉分配鼓风机。炉分配鼓风机包括安装在具有中心驱动轴的驱动马达周围的向后弯曲的叶轮。驱动马达使向后弯曲的叶轮旋转，将空气吸入叶轮入口。优选地，叶轮的入口紧密地安装到炉的入口钟。炉分配鼓风机可以安装到支撑托盘上，使得炉子分配鼓风机能够从叶轮定位在热交换器下方的操作位置和从炉壳内取出叶轮的使用位置移动。与具有壳体的鼓风机相比，消除鼓风机壳体降低了分配鼓风机的成本。

摘要： A draft inducer blower for high efficiency furnaces, including a blower housing which facilitates maximum air flow efficiency through the blower housing while having an overall radial dimension which conforms to the industry standard arrangement of mounting holes on the walls of the furnaces. The blower housing generally includes a housing body and housing cover, the housing body including a plurality of mounting lugs spaced around the housing body through which bolts may be inserted to secure the blower housing to the mounting holes in the wall of a furnace. The housing cover and housing body each define portions of a volute which extends around the outer periphery of the blower housing from the cutoff region to the exhaust transition of the blower housing. The volute includes a cross-sectional area which substantially continuously increases in the axial direction of the blower housing from the cutoff region to the exhaust transition. In this manner, the blower housing has a radial dimension which conforms to the industry standard mounting hole arrangements for furnaces, yet includes a volute having an increasing cross-sectional area around the blower housing to provide a diffuser section within the blower housing to maximize air flow efficiency. The housing cover is positioned close to the impeller periphery to prevent recirculation. The housing cover is provided with a conical section and ribbing to minimize assembly-caused inlet deflection and to optimize air flow.
摘要翻译：一种用于高效炉的牵引式送风机，包括鼓风机壳体，其通过鼓风机壳体有助于最大的空气流动效率，同时具有符合炉壁上的安装孔的工业标准布置的整体径向尺寸。鼓风机壳体通常包括壳体和壳体盖，壳体主体包括围绕壳体主体间隔开的多个安装凸耳，通过该壳体本体可插入螺栓以将鼓风机壳体固定到炉壁中的安装孔。壳体盖和壳体各自限定从鼓风机壳体的外周边延伸的蜗壳的从截止区域到鼓风机壳体的排气过渡的部分。蜗壳包括从截止区域到排气过渡部的鼓风机壳体的轴向方向上基本上连续增加的横截面面积。以这种方式，鼓风机壳体具有符合用于炉的工业标准安装孔装置的径向尺寸，还包括具有围绕鼓风机壳体的增加的横截面积的蜗壳，以在鼓风机壳体内提供扩散器部分以使空气最大化流动效率。外壳盖靠近叶轮周边定位，以防再循环。壳体盖设置有锥形部分和肋条，以最小化组装引起的入口偏转并优化气流。
