3、, no corrosion to steel.The delivery gas by 4-72-8c centrifugal fan shall not contain viscous substances, dust and hard particles containing is no more than 150mg / m3, the temperature of the gas shall not exceed 80 二.型式 從電機(jī)端正視，凡葉輪按順時針方向旋轉(zhuǎn)者均稱“右旋風(fēng)機(jī)”，以“右”表示，反之則均稱之為“左旋風(fēng)機(jī)”以“左”表示。 風(fēng)機(jī)的出風(fēng)口位置以機(jī)殼的出風(fēng)口角度表示，；4-

4、72-8c出風(fēng)口調(diào)整范圍是0225°,間隔是45°，訂貨時需注明，若未注明，均按常規(guī)方式。2. TypeFrom the motor end face, where the impeller rotates clockwise are called "right cyclone machine", note "right", which are called "left cyclone machine",note "left" .The fan air outlet position is sh

5、owed by the case of air outlet angle of the case; the outlet air adjustment range of 4-72-8c is 0 225 °, interval is 45 °, specify when ordering, if not specified, all in the usual way.3. 結(jié)構(gòu)4-72-8c型離心通風(fēng)機(jī)主要由葉輪、機(jī)殼、進(jìn)風(fēng)口、電機(jī)、傳動等部分組成。3. StructureA fan of 4-72-8C mainly consists of impeller, case,

6、 air inlet, drive and motor.四.性能與選擇在風(fēng)機(jī)新安裝后開始正式運(yùn)轉(zhuǎn)時或在使用過程中發(fā)生流量過大或過小時，可采用下列方法之一消除之： 1) 利用節(jié)流裝置的起閉度調(diào)節(jié)流量。 2) 改變風(fēng)機(jī)的轉(zhuǎn)速調(diào)節(jié)流量。3) 調(diào)換新的壓力較高的或較低的風(fēng)機(jī)調(diào)節(jié)流量。 4) 改變管網(wǎng)阻力,用管網(wǎng)阻力系數(shù)調(diào)節(jié)流量。4.Function&Selection After the new installation fan，the flow is too large or too small when began formal operation or in the use proces

7、s. You can remove it using one of the following methods: 1) Using the close degree of throttle device to regulate the flow. 2) Change the fan speed,adjust the flow. 3) Replace a new high or low pressure fan to regulate the flow. 4) Change the pipe resistance, regulate the flow using the pipe resista

8、nce coefficient. 必須指出的是:一般都是采用節(jié)流裝置來調(diào)節(jié)流量,但當(dāng)實(shí)際流量比需要流量大的很多時，這種方法浪費(fèi)電力過多，如果條件允需，通常采用降低風(fēng)機(jī)轉(zhuǎn)速或調(diào)換壓力較低的風(fēng)機(jī)。 It must be pointed out that: generally use throttling device to adjust the flow, but when the actual flow is much larger than the requiring flow , this method wastes too much power, if conditions allow,

9、usually reduces fan speed or replace a low pressure fan. 當(dāng)節(jié)流裝置全開時,流量仍嫌過小，此時節(jié)流裝置已失去節(jié)流作用，故應(yīng)設(shè)法減小管網(wǎng)阻力系數(shù)，以增加流量,也可采用增加風(fēng)機(jī)的轉(zhuǎn)速和調(diào)換壓力較高的風(fēng)機(jī)，但電動機(jī)直聯(lián)和聯(lián)軸器直聯(lián)的風(fēng)機(jī)一般都不能改變轉(zhuǎn)速,只有皮帶傳動的風(fēng)機(jī)可改變皮帶輪直徑的大小以增減轉(zhuǎn)速，切記風(fēng)機(jī)的最大轉(zhuǎn)速不可超過性能表所列最高轉(zhuǎn)速，并核算電機(jī)功率。 When the throttle device fully open, the flow is still small, the throttling device has l

10、ost the throttling effect, therefore, should try to reduce the flow resistance coefficient to increase the flow, but also can be used to increase the fan speed and change a higher pressure fan, but motor direct connection and coupling direct wind machine typically can not change the speed, fan only

11、drive belt can change the diameter of the belt wheel size to increase or reduce the speed, maximum speed can not exceed the performance speed in the table, and calculate the motor power.五.安裝與使用在安裝前首先應(yīng)準(zhǔn)備好安裝所需材料和工具，對風(fēng)機(jī)各部機(jī)件進(jìn)行全面檢查，對葉輪、機(jī)殼、主軸 和軸承等機(jī)件更應(yīng)特別細(xì)致檢查，如發(fā)現(xiàn)損傷，應(yīng)予修復(fù)，然后用煤油清洗軸承箱內(nèi)部。5.Installation&Usage

In some of the bonding surface, in order to prev

14、ent rust, reducing the disassembly difficulty, should be coated with a layer of lubricating oil or lubricating oil.2. When put on the joint bolt on bonding surface, if has a positioning pin ,pin should be good, then tighten the bolts.3.Check the housing and other housing, should not fall and legacy

15、tools or sundries. 安裝要求 Installation requirements 1.安裝風(fēng)機(jī)時，輸氣管道的重量不應(yīng)加在機(jī)殼上，按圖紙校正進(jìn)風(fēng)口與葉輪的軸向和徑向間隙尺寸， 日保持軸的水平位置。 2.安裝進(jìn)風(fēng)口管道時，可以直接利用進(jìn)風(fēng)口本身的螺栓聯(lián)接，此時進(jìn)風(fēng)口的固定是靠三個沉頭螺釘。 3.出風(fēng)口被安裝成某一角度時，后盤適當(dāng)旋轉(zhuǎn)使標(biāo)牌在水平位置，其中4-47-8c角鋼法蘭面應(yīng)保 4.安裝4-72-8c式風(fēng)機(jī)時，利用千分表和塞尺，測量風(fēng)機(jī)主軸和電機(jī)軸的同軸度及聯(lián)軸器兩端 平行度，兩軸同軸度允差為005 mm，聯(lián)軸器端面平行度允差為01 mm。 5.風(fēng)機(jī)安裝后，用手試撥轉(zhuǎn)子，檢查

20、ulley or coupling protective cover, if the air inlet is not connected with pipes, also need to add protection net or other safety devices (optional), other components installed according to the drawing. 由于風(fēng)機(jī)主軸轉(zhuǎn)數(shù)n與內(nèi)功率N之間有如下關(guān)系： 因此在電機(jī)容量不改變時，主軸轉(zhuǎn)速不宜更改，若主軸轉(zhuǎn)速增大，電機(jī)有過負(fù)荷被燒之險。Because the fan spindle speed (n)

21、and power (N) have the following relationship between: Therefore if the motor capacity does not change, the spindle speed should not be changed, if the spindle speed increases, motor overload burned risk.風(fēng)機(jī)所配電機(jī)功率，系指在特定工況下，正常功耗加上機(jī)械損失和應(yīng)有的儲備量而言，并非出風(fēng)口全開時所需功率。如風(fēng)機(jī)出口或入口不接管路或未加外界阻力而進(jìn)行空轉(zhuǎn)，則電機(jī)亦有被燒之險。為安全起見，應(yīng)在風(fēng)機(jī)

22、的出口或入口管路中添加閥門，起動時將其關(guān)閉，運(yùn)轉(zhuǎn)后再將閥門逐漸慢慢開啟，直到規(guī)定工況為止，并注意電機(jī)的電流是否超標(biāo)。The motor power of the fan, refers to the specific conditions, the normal power consumption and mechanical loss and its reserves, is not a required power when outlet air open. The wind machine entrance or exit not connected with pipeline or w

23、ithout external resistance and idle, the motor have been burnt insurance. For the sake of safety , should be added in the fan exit or entrance pipeline, when starts ,close it,after running open the valve gradually , until a predetermined condition, and pay attention to the motor current whether it e
