风机主要由叶轮、机壳、进风口、调节门、传动部分等组成。

1、叶轮：由后倾机翼形的叶片（单吸入 12 片，双吸入 24 片）焊接于弧锥形的前盘与平板形

的后（中）盘中间。由于采用了机翼形叶片，保证了风机高效率、低噪声、高强度。考虑到风机叶

轮的尘粒磨损问题，增大了机翼形叶片头部的实心部分，延长了叶轮的使用寿命。整个叶轮用高强

钢制作，并且叶轮经过动平衡校正。为安全运行提供了可靠保证。同一机号的通、引风机叶轮结

构相同。

3. Main structureFan is made up of impeller, fan casing, inlet suction, damper, driving device etc.

3.1 impeller:Back-curved airfoil blades of impeller(12 blades for single-suction fan and 24 blades for double-suctionfan) are welded between cone front disc and back (middle) disc. The airfoil blades ensure fan features highefficiency, low noise and high strength. The blades tips improve to extend the service life of impellerbecause of the dust or particles. The impeller made of high strength steel also should be done the dynamicbalance test so as to ensure the reliable operation. The impeller structure for same model of centrifugalfans (induced draught fans) are the same.

2、机壳：机壳是采用普通钢板焊接而成的蜗形体。在机壳进口处，增加了适用与该型风机的

进气箱，减小了风机的机壳以及风道的振动，在机壳和进气箱的外部焊有适当高度的井字筋板，提

高了机壳的刚性。机壳上适当的位置开有检测门、清灰门等便于检查及清除叶轮和机壳粉尘堆积。

3.2 Fan casing : fan casings made of steel structure are welded into volute. Inlet box is equipped with fanat inlet to reduce the vibration of fan casings and air ducts. Reinforced ribs shaped "well" are weldedoutside the fan casings and inlet box to enhance fan casing rigidness. An inspection door anddust-removing door are on the fan casings and inlet box to carry out the routine check and remove thecontamination on the impeller and fan casings.

3、进风口：收敛式流线的进风口制成整体结构，用螺栓固定在风机入口侧。

3.3 Inlet suction: integral convergent flowing-line structure. It is fastened with bolts at inlet of fan .

4、调节门：用以调节风机流量的装置。采用在进气箱的进口处装有五个翼形叶片的差动调节

门，用以调节风机的特性，调节叶片的支撑处装有滚动轴承，转动灵活，使用可靠，调节范围由 90

°（全闭）到 0°（全开）。调节门配合电动执行器操动，能方便的进行流量的调节。

为使调节门各部件正常工作，必须很好的润滑。对通风机的调节门，采用钙钠基润滑脂润滑；

对引风机，因气温较高，采用二硫化钼高温润滑脂润滑

3.4 Damper: It is used for regulating the volume. Differential inlet damper with 5 airfoil blades mounted infront of the fan inlet box is used to control the fan inlet volume. The guard vanes can rotate flexibility from0 to 90°(from fully open to fully closed) with the help of the rolling bearings on the guard vanes supports.Damper is equipped with the electric actuator, which can regulate the volume easily.

The good lubrication can ensure the normal operation of the parts of the damper, so the grease of thedamper of centrifugal fan is calcium-sodium base grease. The grease of induced draught fan ismolybdenum disulfide high temperature grease because of high temperature.

5、传动部分：主轴由优质钢制成，轴承箱按情况（风机的叶轮直径大小和转速的高低不同）选用滚

动轴承或滑动轴承。轴承箱上装有温度计和油位指示器，润滑油采用30#机械油，加入油量按油位标志的

要求。润滑油需过滤后才能注入轴承箱。安装时，需加装输水管，耗水量随气体温度不同而异。

3.5 Driving device: Main shaft is made of high quality steel. Rolling bearings or slide bearings are adoptedaccording to the bearing box (impeller diameter and different speed). Thermometer and oil indicator aremounted on the bearing box. Lubrication oil is 30# mechanical oil. The oil charging amount should dependon the oil level. Oil cannot be charged into the bearing box until filtering. When installation, water pipesshould be mounted, the water consumption changes over the gas temperature.

2、风机的选择

如使用条件为前述给定条件下所需的全压、流量，可按性能表选用风机。如使用条件与标准情

况不符时，可按前述公式换算出的性能选用风机。风机出厂检验性能是在设计流量时，全压值的偏

差不得超过设计全压值的±5%。

4.2 Fan selectionIf fan total pressure , volume under the operation condition is similar to above-mentioned standard

condition in the performance data sheet, select fan according to performance data sheet. If fan operationcondition is not the same as the standard condition, select the fan according to above formula. Performancetest before delivery is subject to the designed volume, the total pressure error should not exceed +/_5%。ofthe the designed total pressure.

3、流量过多或不足的处理：

在使用风机时，常常发生流量过多或不足的现象。产生这种现象的原因很多，如果是在使用过

程中发生这种现象，主要是由于管网中的阻力时大时小。如果是在使用过程中，经过较长的时间逐


6

渐减少，或在短时间内突然减少，则主要是由于管网堵塞。

4.3 overabundance or shortage in volumeDuring the operation of the fan, overabundance or shortage in volume can occur very often, there are

a large number of the causes. If it occurs during the operation, it is caused by the large or small resistanceof ducts network. If it reduces gradually during the operation condition, or reduces suddenly for a shorttime, it is caused by the ducts network clogging.

在风机新安装后，进行正式运转就发生流量过大或不足的现象，其原因主要是管网阻力实际值

与计算值相差过大或选择风机时未考虑风机本身全压偏差的影响。

After new fan installation, volume is overabundance or shortage during normal operation, it is mainlycaused by the big difference between actual and calculated value of ducts network resistance or notallowing for total pressure error influence on fan.

风机发生流量过多或不足时可采用以下方法消除：

⑴．利用调节门的开闭程度调节流量。

⑵．改变风机转速调节流量。（注：如超过性能表中给定的风机转速，必须针对设计、生产。）

⑶．改变管网阻力系数调节流量。

remedy for overabundance or shortage of volume:(1)Regulate the volume of the damper opening.(2)change fan speed to regulate the volume (note: fan speed is more than given speed in the

performance data sheet, specially in design and manufacture).(3)Change ducts network resistance coefficient to control the volume.

当调节门全开时，流量仍过小，此时可设法改变管使网阻力系数减小，以增加流量，也可增加

风机的转速，但转速不得大于性能表中的最大转速。

When damper is open fully, but volume is still very small, try to change the ducts to reduce the ductsnetworks resistance coefficient and increase the volume and fan speed, but fan speed cannot exceed themax. speed given in the performance data sheet.

在安装前首先应准备好安装用的材料工具，并对风机各部分的机件进行检查，对叶轮、主轴和

轴承等机件应特别细致检查，如发现损伤，应予以修好，然后用煤油清洗轴承箱内部。

在安装操作过程中必须注意下列几点：

⑴ 在一些结合面上，为防止生锈，减少拆卸困难，应涂上一些润滑脂或机械油。

⑵ 在上结合面的螺栓时，如有定位销钉，应先上好销钉，再拧紧螺栓。

⑶ 检查机壳与其它壳体内部，不应有掉入和遗留的工具和杂物。
