Title (EN) MULTI-VANE CENTRIFUGAL BLOWER
(FR) SOUFFLANTE CENTRIFUGE A AILETTES MULTIPLES
(JA) 多翼遠心送風機
Abstract:
(EN) A multi-vane centrifugal blower, wherein a large number of vanes (33), (33), ... are fixedly disposed on a hub (31) drivingly rotated around its axis while keeping specified distances in the circumferential direction in an impeller (3) stored in a fan housing (4). An annular member (32) for reinforcement is installed on the vanes (33), (33), ... on the opposite side of the hub (31). A bell mouth (7) having a recessed part (7a) is installed around the air suction port (5) of the fan housing (4). Air suction port side end parts (33d), (33d), ... positioned on the vanes (33), (33), ... on the opposite side of the hub (31) are inserted into the recessed part (7a) of the bell mouth (7) without a shroud.
(FR) L'invention concerne une soufflante centrifuge à ailettes multiples dans laquelle un grande nombre d'ailettes (33), (33), ... sont montées fixes sur un moyeu (31) entraîné rotatif autour de son axe; des distances prédéterminées séparent les ailettes dans une direction circulaire d'une turbine (3) disposée dans un boîtier de ventilateur (4). Un organe annulaire de renforcement (32) est monté sur les ailettes (33), (33), ... du côté opposé du moyeu (31). Une bouche évasée (7) comprenant une partie enfoncée (7a) est montée sur l'orifice d'aspiration d'air (5) dans le boîtier de ventilateur (4). Les parties d'extrémité (33d), (33d) ... placées sur les ailettes (33), (33), ... sur le côté opposé du moyeu (31) sont insérées dans les parties en retrait (7a) de la bouche évasée (7) sans aucun carénage.
(JA) 多翼遠心送風機では、ファンハウジング(4)に収納される羽根車(3)において、軸芯周りに回転駆動されるハブ(31)に対し、多数の翼(33),(33)・・・が周方向に所定の間隔を保って配設・固定される。また、翼(33),(33)・・・のハブ(31)と反対側には、補強用の環状部材(32)が設けられる。ファンハウジング(4)の空気吸込口(5)の周囲には、凹部(7a)を有するベルマウス(7)が設けられる。各翼(33),(33)・・・の上記ハブ(31)と反対側に位置する空気吸込口側端部(33d),(33d)・・・は、シュラウドを有することなく、ベルマウス(7)の凹部(7a)に挿入される。
