High-air-flow low-noise vertical type mounting axial flow fan for comprehensive pipe rack
The invention discloses a high-air-flow low-noise vertical type mounting axial flow fan for a comprehensive pipe rack. The fan comprises an air cylinder, a motor, a hub and blades, the motor is fixedly connected to the interior axis of the air cylinder trough connecting plates, the hub is fixedly connected to an output shaft of the motor, the blades are fixedly connected to the side wall of the hub, the axial flow fan further comprises an air outlet flow equalizing noise elimination guide blade, the air outlet flow equalizing noise elimination guide blade is located at one end of the air cylinder, through the air outlet flow equalizing noise elimination guide blade at one end of the air cylinder, before an air flow generated in the fan flows out of the air cylinder, the air flow firstly flows through the air outlet flow equalizing noise elimination guide blade, a part is a dedicated noise elimination device customized and designed according to the flow and the pressure energy magnitudeof the pneumatic property, a main material comprises a galvanized steel sheet, a galvanized silenced perforated plate and a noise elimination cotton material, the flow equalizing guide blade is madeof the galvanized silenced perforated plate and the noise elimination cotton material, and the sound power noise of the air flow flowing through the fan can be efficiently reduced.
本发明公开了综合管廊用大风量低噪声立式安装轴流风机，包括风筒、电机、轮毂和叶片，所述电机通过连接板固定连接在所述风筒的内部轴心处，所述轮毂固定连接在所述电机的输出轴上，所述叶片固定连接在所述轮毂的侧壁上，还包括有出风口均流消声导叶，所述出风口均流消声导叶位于所述风筒的一端通过在风筒的一端设置出风口均流消声导叶，风机内部产生的气流在流出风筒之间，率先流过出风口均流消声导叶，该部件是按气动性能的流量、压力能量级，定制设计的专用消声装置；主要材料为镀锌钢板、镀锌消声多孔板、消声棉材料；均流导叶采用镀锌消声多孔板、消声棉材料，能高效降低流经的气流的声功率噪声。
