Description

一种船用闭式风机
技术领域
本发明涉及一种风机，具体说是一种船用闭式风机。
背景技术
随着我国船舶事业的发展，船舶运营需要更多高科技、高水平的设备，其中用于改善舱室环境的通风系统属于较为重要的部分，常用的风机进行通风时，电机放置在壳体外，需要配置冷却风扇，在长期运行以及海洋波浪环境下工作，振动大、噪音大，无法满足现有静音通风的要求。
发明内容
针对上述不足，本发明提供了一种结构简单，减振降噪的船用闭式风机。
本发明采用的技术方案是：一种船用闭式风机，其特征在于：包括前外壳、前中外壳、后中外壳、后外壳、电机、前叶轮、前导叶体、后叶轮和后导叶体，前叶轮、前导叶体设置于由前外壳、前中外壳连接成的前半壳内，后叶轮和后导叶体设置于由后外壳、后中外壳连接成的后半壳内，前中外壳与后中外壳前后连接完成前、后半壳的连接，前导叶体上穿接固定电机，电机的前出轴伸至前叶轮内并连接前叶轮，电机的后出轴伸至后叶轮内并连接后叶轮。
所述前外壳、后外壳为波浪状，前、后叶轮、前、后导叶体外型对应呈波浪状。
本发明采用电机穿接固定在整体壳体内的的前中导叶体上，电机无需配置冷却风扇，减少噪音源，可有效降低风机的噪音，满足静音通风要求；采用电机的前、后出轴连接前、后叶轮，电机前、后支撑稳定，有利于减少工作振动，配合由壳体与叶轮、导叶体间形成的波浪形通风通道，有效增强风机的气动性能，提高使用效果。
附图说明
图1为本发明结构示意图。
图中：前外壳1、前中外壳2、后中外壳3、后外壳4、电机5、前出轴51、后出轴52、前叶轮6、前导叶体7、后叶轮8、后导叶体9。
具体实施方式
以下结合附图和实施例作进一步说明。
图1所示：一种船用闭式风机包括前外壳1、前中外壳2、后中外壳3、后外壳4、电机5、前叶轮6、前导叶体7、后叶轮8、后导叶体9，前叶轮6、前导叶体7设置于由前外壳1、前中外壳2连接成的前半壳内，后叶轮8和后导叶体9设置于由后外壳4、后中外壳3连接成的后半壳内，前中外壳2与后中外壳3前后连接完成前、后半壳的连接，前外壳、后外壳为波浪状，前、后叶轮、前、后导叶体外型对应呈波浪状，由此形成波浪状的风道，前导叶体7上穿接固定电机5，电机5的前出轴51伸至前叶轮内并连接前叶轮6，电机的后出轴52伸至后叶轮内并连接后叶轮8。
