| description | The utility model provides an impeller which comprises a blade fixing top plate (10) with an air inlet. A blade fixing bottom plate (7); the blades are fixed between the blade fixing top plate (10) and the blade fixing bottom plate (7), the blades comprise short blades (8) and long blades (9), the short blades (8) and the long blades (9) are arranged in a staggered mode, and the short blades (8) and the long blades (9) extend outwards in the radial direction. The utility model further provides a centrifugal fan device which comprises the impeller. The fan and the centrifugal fan device have the advantages of being low in energy, low in noise and high in negative pressure.
本实用新型提出一种叶轮，包括：具有进风口的叶片固定顶板(10)；叶片固定底板(7)；叶片，所述叶片固定于叶片固定顶板(10)和叶片固定底板(7)之间，所述叶片包括：交错布置的短叶片(8)和长叶片(9)，短叶片(8)和长叶片(9)径向向外延伸。本实用新型还提出一种离心风机装置，其包括如前所述的叶轮。本实用新型的风机和离心风机装置具有低能高、低噪音、高负压的优点。 |
