【产品手册】离心通风机产品使用说明书

1、.离心通风机产品使用说明书用途4-72型离心通风机主要用处是为一般工厂及大型建筑物的室内通风换气或输送空气及其它不自燃、不易爆、不挥发、对人体无害、对钢材无腐蚀性之气体。但输送的气体不得含粘性物质，所含尘土及硬质颗粒物不大于150mg/m3，气体温度不得超过80。4-72型离心通风机在我国是使用最早的风机，然而也是使用最普通的风机，从高层建筑到地下铁道，从锅炉鼓风到厂房换气，从北部边疆到南海之滨，从西部高原到东部边垂，随处可见。型式从电机一端正视，凡叶轮按顺时针方向旋转者均称“右旋风机，以“右表示，反之那么均称之为“左旋风机，以左表示。风机的出风口位置以机壳的出风口角度表示，4-72型风机No

2、2.86在出厂时均做成一种型式，使用单位根据要求再安装成所需要的位置，订货时无须注明。其中：No2.8出风口位置调整范围是0225，间隔是45；No3.26出风口调整范围是0225，间隔是22.5；No812出风口调整范围是0225，间隔是45；No16、20出风口角度制成固定的0、90、180三种，不能调整，订货时需注明。风机的传动方式有A、B、C、D四种：No2.85采用A式传动，No6既有A式传动又有C式传动，No812采用C、D式两种传动方式，No1620采用B式传动。如上述机号、传动方式、出口角度不能适应您的消费需要，我厂有才能为您改造或设计，直至您满意为止。结构本风机No2.8A6

3、A主要由叶轮、机壳、进风口、电机等部分组成，No6C和No820除具有上述构造外，还有传动部分。叶轮由10个后倾机翼型叶片、曲线型轮盖和平板后盘组成，经动静平衡校正和超速运转实验，效率高，运转平稳可靠，空气性能良好。机壳用普通钢板焊接成蜗壳形整体。进风口制成整体构造，装于风机一侧，与轴向平行的截面为曲线形状，作用是能使气流顺畅进入叶轮，且损失较小。传动由主轴、轴承箱、滚动轴承、皮带轮或联轴器组成。安装与使用在安装前首先应准备好安装所需材料和工具，对风机各部机件进展全面检查，对叶轮、机壳、主轴和轴承等机件更应特别细致检查，如发现损伤、应予修复，然后用煤油清洗轴承箱内部。在进展安装操作过程中必须注

4、意以下三点：1、 在一些接合面上，为了防止生锈，减少拆卸困难，应涂上一层光滑油或机械油。2、 在上接合面的螺栓时，如有定位销钉应先上好销钉，再拧紧螺栓。3、 检查机壳内及其它壳体内部，不应有掉入和遗留的工具或杂物。安装要求：1、 安装风机时，输气管道的重量不应加在机壳上，按图纸校正进风口与叶轮的轴向和径向间隙尺寸，且保持轴的程度位置。2、 安装进风口管道时，可以直接利用进风口本身的螺栓联接，此时进风口的固定是靠三个沉头螺钉。3、 出风口被安装成某一角度时，后盘适当旋转使标牌在程度位置，其中No8-12角钢法兰面应保持程度。4、 安装No8-12D式风机时，利用千分表和塞尺，测量风机主轴和电机轴

5、的同轴度及联轴器两端平行度，两轴同轴度允差为0.05mm，联轴器端面平行度允差为0.1mm。5、 风机安装后，用手试拨转子，检查是否有过紧或刮蹭等现象，接线是否正确，其它保险设施是否完善，转动部分或进出方向是否人已分开，在确保平安前方可进展试运转。6、 电机安装后，安装皮带轮或联轴器防护罩，如进气口处不接收道时，也需加防护网或其它平安装置用户自备，其它部件照图安装。由于风机主轴转数n与内功率N之间有如下关系：=因此在电机容量不改变时，主轴转速不宜更改，假设主轴转速增大，电机有过负荷被烧之险。风机所配电机功率，系指在特定工况下，正常功耗加上机械损失和应有的储备量而言，并非出风口全开需功率。如风机

6、出口或入口不接收道或未加外界阻力而进展空转，那么电机亦有被烧之险。为平安起见，应在风机的出口或入口管路中添加阀门，起动时将其关闭，运转后再将阀门逐渐渐渐开启，直至规定工况为止，并注意电机的电流是否超标。维护1、 定期去除风机及输气管道内的灰尘、污垢及水等杂质，并防止生锈。2、 风机修理时必须先断电停机，绝对不允许在运转中进展，开关应由专人监护，以防中途送电。3、 对温度计及油标的灵敏性应定期检查。4、 除每次拆修后应更换光滑油外，还应定期更换光滑油。5、 每次维修前后均应仔细记录、清点、核对工具及原材料数量，以防遗忘在风机及管道内部。6、 风机试车时进出口方向十米之内不许站人。7、 安装、维修

7、及试车时严禁无关人员在场围观。故障及原因风机的主要故障有：一、 轴承箱振动剧烈。1、 风机轴与电机轴不同心，联轴器歪斜。2、 机壳或进风口与叶轮摩擦。3、 根底的刚度不够或不结实。4、 叶轮铆钉松动或轮盘变形。5、 叶轮轴盘与轴松动，联轴器螺栓松动。6、 机壳与支架、轴承箱与支架、轴承箱与座等联接螺栓松动。7、 风机进、出口管道安装不良，产生振动。8、 转子不平衡。9、 管见过细，风速过快。二、 轴承温升过高。1、 轴承箱振动剧烈。2、 光滑脂质量不良、变质或填充过多、含有灰尘、砂粒、污垢等杂质。3、 轴承箱盖、座联接螺栓之紧力过大或过小。4、 轴与滚动轴承安装歪斜，前后两轴承不同心。5、 滚

8、动轴承损坏。三、 电动机电流过大和温升过高。1、 开车时进气管道内闸门或节流阀未关严。2、 流量超过规定值或风管漏气。3、 风机输送的气体中含粘性物质或气温太低，气体密度太大。4、 电机输入电压过低或电源单相断电。5、 联轴器联接不正，皮圈过紧或间隙不匀。6、 受轴承箱振动剧烈的影响。7、 受并联风机工作情况恶化或发生故障的影响。四、 皮带滑下两皮带轮应该相对应的槽没对正。五、 皮带跳动两皮带轮间隔 较近或皮带过长。订货须知订货时必须注明风机的机号、风量、压力、出风口角度、旋转方向以及电动机型号功率、转速等。4-72N o2.8A、3.2A、3.6A离心通风机性能与选用件表机号传动方式转速r/
