Centrifugal Ventilator

Detailed description

一、风机的用途

    9-19、9-26型离心通风机,与国内外同类风机相比,具有效率高,噪声较低,性能曲线平坦,高效区宽广,具有七十年代先进水平。本风机一般用于锻冶炉及高压强制通风,并可广泛用于物料输送、输送空气及特殊气体。输送特殊气体时,风机须进行特殊处理。

 

二、风机的形式

         1、本风机可制成单吸入,机号有No4、4.5、5、5.6、6.3、7.1、8、9、10、11.2、12.5、14、16共十三个机号。根据用户需要,也可制成介于其中的其他机号。
  2、通风机又可制成右旋转或左旋转两种形式,从电机一端正视,如叶轮按顺时针方向旋转称右旋风机,以"右"表示。按逆时针方向旋转,称左旋风机,以"左"表示。
  3、风机的出口位置以机壳的出口角度表示"左""右"均可制成0 共六种角度。
  4、风机的传动方式为A式(4~6.3)和D式(7.1~16)两种

 

三、主要组成部分的结构特征

风机中No4~6.3主要由叶轮、机壳、进风口、支架等组成。No7..1~16主要由叶轮、机壳、进风口、传动组等组成。
  1、叶轮:9-19型风机叶片为12片,9-26型风机叶片为16片。均属前向弯曲叶型,叶轮扩压器外缘最高圆周速度不超过140米/秒。叶轮成型后经静、动平衡校正。因此,运转平稳可靠。
  2、机壳:用钢板焊接成蜗形壳整体。
  3、进风口:作成收敛式流线形的整体结构用螺栓固定在前盖板组。
  4、传动组:由主轴、轴承箱、联轴器等组成。主轴由优质钢制成,轴承箱整体结构,采用滚动轴承,滚动轴承用轴承润滑脂润滑。

2, Ventilator can be Rotate Left or Rotate Right.
3, fan exit can be six angles according to the angle of main case.
4, The fan driving mode can be A type(4~6.3) and D type(7.1~16).

 

Third, main components' structure property

In the fan No4~6.3 are mainly made up of impeller, main case, air intake, bracket and so on. No7..1~16 is made up of impeller, main case, air intake, Transmission group.
1, impeller: 9-19 type fan blade can be 12 pieces, 9-26 type fan blade can be 16pieces.
2, main case: Steel plate welded into a whole volute shell.
3, air intake: Made the overall structure convergent streamline the front cover with a fixed set of Bolt .

4, Transmission group: It is made up of principal axis, bearing housing, coupler and so on.

.
