防爆排风机正视图

dZF防爆排风机外形图和详细技术资料
一、概述:
dZF型系列低噪声防爆排风机是新一代低噪声轴流、离心通风机产品(原型号是:防爆轴流风机BT-35、防爆离心风机BF4-72、防爆移动风机BYDF32、防爆屋顶风机BDW……),该机采用优化空气动力学原理设计和先进的加工技术制造,整机结构合理、坚固、安全实用,具有风量大,风压高、噪声低、耗电少、重量轻及在同一安装位置下,可实现反向通风等优点,与现时国内普遍使用的轴流风机相比,风量提高42%,风压提高30%,噪声(A声级)降低10—18dB(A),全压效率最高达82.3%。
dZF型防爆防爆排风机以其新颖、独特的设计,卓越的性能,超前的水平而独树一帜,深受用户欢迎,并在中国新技术新产品博览会上荣获金奖。
dZF型防爆排风机按叶轮直径不同,有十二种型号规格,即:3.15、4、4.5、5、5.6、6、6.3、7.1、8、9、10、11.2、每台机叶片数为8—14片,叶片安装角度有15—40六种,可作无级调节。
dZF型防爆排风机输送无腐蚀,无明显灰度气体,气体温度不超过60℃。其叶轮部由低镁铝合金制成,且有隔爆性能,因此在配套隔爆电机后,可输送易燃性气体。
二、结构特征:
1、叶轮部:叶片为变截面空间扭曲机翼形叶片,轮壳采用无道风对夹式、结构均为铝合金精密压铸成形,叶片由对夹式轮壳定位,叶片安装角度可按用户需要任意调整,也可以调整到使叶片产生反问流动,实现反向通风的需要。2、机壳部:标准结构是水平卧式,集风器根据气流的方向可安装在风机的任—侧,拆除支架嵌人墙内为墙式安装;拆除集风器接人管道为管道式安装。3、电动机:根据不同的使用要求,采用两种不同形式的电机配套。其一,标准型:采用低风
阻,杆式支承型系列电机,电源线由钢管引出机外,电机接线盒安装干机壳外侧。其二,埋墙型:采用Y系列轴流风机专用电机线或普通Y系列卧式电机,此种电机配套,最适合于风机埋入墙内,进行室内排风或室外送风使用。
三、安装要求:
1、整机安装前应仔细检查风机的各部位是否有损坏,变形,松动和末紧固的现象。2、检查叶片与风筒之间有没有擦碰现象。3、检查电机旋转力向是否与叶片上的指示方向一致,如果不—致,要改变电机接线。4、电机绝缘是否正常,机壳外部接地电线必需正确联接。
四、维护:
1、风机的使用环境不得在有过多硬质尘粒、过多水蒸汽、腐蚀性气体中长期使用。2、风机在全部和个别叶片损坏的情况下,只需更换叶片就可正常工作。3、风机运转过程中噪声过大,震动过大等情况时应及时进行检修。
