一、Y5-47、Y5-48锅炉离心引风机概述
1、用途
Y5-47II'型锅炉离心引风机适用于燃用各种煤质并配有消烟除尘装置的02~20t/h锅炉,凡进气条件相当,性能又相适应者,均可采用。但最高温度不得超过250℃;
2、形式及特点
(1)形式
(1)引风机制成单吸入,机号有No3.15,4,5,6,7,8.9,10,11,12,12.4十一种。
(2)引风机可制成左旋转或右旋转两种形式。从传动组一端正视风机,如叶转顺时针旋转称为右旋转,以“右”表示。逆时针旋转称为左旋转,以“左”表示。
(3)风机的出风口位置以机壳的出风口角度表示。“左”“右”均制成0°、90°、180°三种角度。
(4)风机的传动方式为C式,D式,电动机与风机联接分别采用带轮传动和弹性联轴器直接传动。
(2)特点
Y5-47II型风机是在原Y5-47型风机基础上的改进产品,该风机最佳工况点的全压内效率为85.6%,噪音指标(A声级)为12.5dB。
Y5-47II型风机是在原Y5-47型风机相比较,由于进行了一系列改进,使噪声值有显著降低,为了更好地满足锅炉配套的要求新增加了No.3.15C(配0.2-0.5t/h锅炉)!4D(配0.7-1t/h锅炉)!5D(2t/h锅炉)!6D(配4t/h锅炉)!7C(配4t/h,6t/h锅炉)!10D(配6t/h锅炉)!11D(配10t/h锅炉)共7种1l号。
在当前工业锅炉系列型号较多,燃用煤质优质悬殊,配用的除尘器及安装管道阻力不一,所需的引风机的风量,风压差异较大,为适用上述情况,考虑到风机的经济性及运转平稳可靠性,该风机采用D式,C式两种传动方式(即联轴器与V带传动)其中0.7~20t/h的锅炉均有D式传动的引风机与之匹配,0.2~10t/h的锅炉均有C式传动的引风机与之匹配,对于V带传带使用单位可根据实际情况自行变换主轴转速来获得较理想的风量,风压。
3、结构特点
该风机主要由叶轮、机壳,进风口,传动组和调节门等部分组成;
(1)叶轮有12片材料为Q345(16Mn)的后倾平板叶片,焊接于弧锥形轮盖与平板形的轮盘中间,经过平衡校正。因此,运转平稳,有较高的强度和耐磨性,使用寿命较长。
(2)机壳用钢板焊接成蜗形壳体,从No .8以上“左”“右”转通用。
(3)传动组的主轴由优质钢制成采用球轴承(No.3.15-7采用低噪声型轴承),二只并列的轴承座,用2号的钙钠基润滑脂和风叶自冷,结构简单。
(4)进风口为敛散式的进风口,制成整体结构,用螺栓固定在机壳入口处。

1、用途
Y5-48型锅炉离心风机是为适应燃用各种煤质并配有消烟除尘装置的1-2t/h工业锅炉配套设计的。凡进气条件相当,性能又相适应的均可选用。最高温度不得超过250℃,在引风机前必须加装效率不低于85%的除尘装置,降低进入风机的烟气含尘量,以利提高风机寿命。
2、型式
(1)引风机制成单吸入。机号有No.4、5、6.3、8、10,12.5六种。
(2)引风机可制成右旋或左旋两种。从电动机一侧正视风机,如叶轮顺时针旋称为右旋风机,以“右”表示;叶轮逆时针旋转称为左旋风机以“左”表示。
(3)风机的出口位置以风机机壳的出风口角度来表示,‘左”“右”风机均可制成0°、45°、90°、135°、180°、225°六种角度。
3、结构特点
目前工业锅炉系列较多.燃用煤质优质悬殊。配用的除尘器阻力不一,所需引风机的风量、风压差异较大。为了适应上述情况,考虑到风机的经济性均采用V带(C式)传动这样又能以一个机号采用不同转速来满足同一吨位锅炉配置各类除尘器的要求,减少了风机的系列和机号,而且也便于使用单位根据实际情况,选择不同转速来获得所需的较理想的风量、风压。
本风机主要由叶轮、机壳,进风口、调节门、传动组等部分组成。
(1)叶轮有后倾平板叶片1 2片材料为Q345(16Mn).焊接于弧锥形轮盖与平板形轮盘中间,经静、动平衡校正,故运转平稳强度高。
(2)机壳用钢板焊接成蜗形整体。No8以上“左”“右”转通用。在蜗板上还开有清灰门便于清除堆积在叶片上和机壳内的积灰,保证叶轮的平衡性和气动性能。
(3)进风口做成收敛式流线形的整体结构,用螺栓固定在机壳入口侧。
(4)调节门叶片为花瓣形,No.4-63为9片,No.8以上为11片。轴向安装在进风口前面。
由于采用了外部传动的结构,转动灵活方便。调节范围由0°(全开)到90°(全闭)。调节门的扳把位置从进风口方向看在右侧。对“右”旋风机,扳把从下往上推是由全闭到全开方向,对“左”旋风机,扳把从上往下拉是由全闭到全开方向。为使调节门各部正常工作,必须很好地润滑。润滑脂采用二硫化钼高温(260℃)润滑脂,风机在高温运转时仍能保证润滑作用。
(5)传动组由主轴、轴承箱、带轮组成。主轴由优质钢制成,采用球轴承.水冷整体轴承箱,因此,须加装输水管。耗水量随环境温度的不同而异,一般按05-1m3/h考虑轴承箱装有温度计和油位指示器,采用全损耗系统用油L—AN46润滑,加入油量按油位标志的要求。

Y5-47II'型锅炉离心引风机适用于燃用各种煤质并配有消烟除尘装置的02~20t/h锅炉,凡进气条件相当,性能又相适应者,均可采用。但最高温度不得超过250℃;
2、形式及特点
(1)形式
(1)引风机制成单吸入,机号有No3.15,4,5,6,7,8.9,10,11,12,12.4十一种。
(2)引风机可制成左旋转或右旋转两种形式。从传动组一端正视风机,如叶转顺时针旋转称为右旋转,以“右”表示。逆时针旋转称为左旋转,以“左”表示。
(3)风机的出风口位置以机壳的出风口角度表示。“左”“右”均制成0°、90°、180°三种角度。
(4)风机的传动方式为C式,D式,电动机与风机联接分别采用带轮传动和弹性联轴器直接传动。
(2)特点
Y5-47II型风机是在原Y5-47型风机基础上的改进产品,该风机最佳工况点的全压内效率为85.6%,噪音指标(A声级)为12.5dB。
Y5-47II型风机是在原Y5-47型风机相比较,由于进行了一系列改进,使噪声值有显著降低,为了更好地满足锅炉配套的要求新增加了No.3.15C(配0.2-0.5t/h锅炉)!4D(配0.7-1t/h锅炉)!5D(2t/h锅炉)!6D(配4t/h锅炉)!7C(配4t/h,6t/h锅炉)!10D(配6t/h锅炉)!11D(配10t/h锅炉)共7种1l号。
在当前工业锅炉系列型号较多,燃用煤质优质悬殊,配用的除尘器及安装管道阻力不一,所需的引风机的风量,风压差异较大,为适用上述情况,考虑到风机的经济性及运转平稳可靠性,该风机采用D式,C式两种传动方式(即联轴器与V带传动)其中0.7~20t/h的锅炉均有D式传动的引风机与之匹配,0.2~10t/h的锅炉均有C式传动的引风机与之匹配,对于V带传带使用单位可根据实际情况自行变换主轴转速来获得较理想的风量,风压。
3、结构特点
该风机主要由叶轮、机壳,进风口,传动组和调节门等部分组成;
(1)叶轮有12片材料为Q345(16Mn)的后倾平板叶片,焊接于弧锥形轮盖与平板形的轮盘中间,经过平衡校正。因此,运转平稳,有较高的强度和耐磨性,使用寿命较长。
(2)机壳用钢板焊接成蜗形壳体,从No .8以上“左”“右”转通用。
(3)传动组的主轴由优质钢制成采用球轴承(No.3.15-7采用低噪声型轴承),二只并列的轴承座,用2号的钙钠基润滑脂和风叶自冷,结构简单。
(4)进风口为敛散式的进风口,制成整体结构,用螺栓固定在机壳入口处。

1、用途
Y5-48型锅炉离心风机是为适应燃用各种煤质并配有消烟除尘装置的1-2t/h工业锅炉配套设计的。凡进气条件相当,性能又相适应的均可选用。最高温度不得超过250℃,在引风机前必须加装效率不低于85%的除尘装置,降低进入风机的烟气含尘量,以利提高风机寿命。
2、型式
(1)引风机制成单吸入。机号有No.4、5、6.3、8、10,12.5六种。
(2)引风机可制成右旋或左旋两种。从电动机一侧正视风机,如叶轮顺时针旋称为右旋风机,以“右”表示;叶轮逆时针旋转称为左旋风机以“左”表示。
(3)风机的出口位置以风机机壳的出风口角度来表示,‘左”“右”风机均可制成0°、45°、90°、135°、180°、225°六种角度。
3、结构特点
目前工业锅炉系列较多.燃用煤质优质悬殊。配用的除尘器阻力不一,所需引风机的风量、风压差异较大。为了适应上述情况,考虑到风机的经济性均采用V带(C式)传动这样又能以一个机号采用不同转速来满足同一吨位锅炉配置各类除尘器的要求,减少了风机的系列和机号,而且也便于使用单位根据实际情况,选择不同转速来获得所需的较理想的风量、风压。
本风机主要由叶轮、机壳,进风口、调节门、传动组等部分组成。
(1)叶轮有后倾平板叶片1 2片材料为Q345(16Mn).焊接于弧锥形轮盖与平板形轮盘中间,经静、动平衡校正,故运转平稳强度高。
(2)机壳用钢板焊接成蜗形整体。No8以上“左”“右”转通用。在蜗板上还开有清灰门便于清除堆积在叶片上和机壳内的积灰,保证叶轮的平衡性和气动性能。
(3)进风口做成收敛式流线形的整体结构,用螺栓固定在机壳入口侧。
(4)调节门叶片为花瓣形,No.4-63为9片,No.8以上为11片。轴向安装在进风口前面。
由于采用了外部传动的结构,转动灵活方便。调节范围由0°(全开)到90°(全闭)。调节门的扳把位置从进风口方向看在右侧。对“右”旋风机,扳把从下往上推是由全闭到全开方向,对“左”旋风机,扳把从上往下拉是由全闭到全开方向。为使调节门各部正常工作,必须很好地润滑。润滑脂采用二硫化钼高温(260℃)润滑脂,风机在高温运转时仍能保证润滑作用。
(5)传动组由主轴、轴承箱、带轮组成。主轴由优质钢制成,采用球轴承.水冷整体轴承箱,因此,须加装输水管。耗水量随环境温度的不同而异,一般按05-1m3/h考虑轴承箱装有温度计和油位指示器,采用全损耗系统用油L—AN46润滑,加入油量按油位标志的要求。
