4-73C式鍋爐通引風(fēng)機(jī)樣本

1、風(fēng)機(jī)的用途G4-73和Y4-73型鍋爐通、引風(fēng)機(jī)主要適用于火力發(fā)電廠中2670t/h蒸汽鍋爐的通、引風(fēng)系統(tǒng)。在無其它特殊要求時(shí)，G4-73亦可用于在礦井通風(fēng)及一般通風(fēng)。通風(fēng)機(jī)輸送的介質(zhì)為空氣，最高溫度不得超過80°C；引風(fēng)機(jī)輸送的介質(zhì)為煙氣，最高溫度不得超過250C。在引風(fēng)機(jī)前，必須加裝除塵裝置，以盡可能減少進(jìn)入風(fēng)機(jī)中煙氣的含塵量。根據(jù)一般電廠的使用情況，所配除塵器效率不得低于85%。風(fēng)機(jī)的型式1、通風(fēng)機(jī)與引風(fēng)機(jī)均制成單吸入，各有Nq818共11個(gè)機(jī)號(hào)。2、從電機(jī)一端正視，葉輪順時(shí)針旋轉(zhuǎn)者稱右旋風(fēng)機(jī)，以“右”表示；反之為左旋風(fēng)機(jī)，以“左”表示。3、風(fēng)機(jī)的出風(fēng)口位置，以機(jī)殼的出風(fēng)口角度

2、表示。4、風(fēng)機(jī)的傳動(dòng)方式為C式，均采用彈性聯(lián)軸器聯(lián)接。風(fēng)機(jī)的結(jié)構(gòu)風(fēng)機(jī)主要由葉輪、機(jī)殼、進(jìn)風(fēng)口、調(diào)節(jié)門及傳動(dòng)部分組成。1、葉輪12后傾機(jī)翼斜切形葉片焊接于錐弧形前盤與平板后盤中間。由于采用了機(jī)翼形葉片，保證了風(fēng)機(jī)主效率、低噪聲、高強(qiáng)度。葉輪經(jīng)靜動(dòng)平衡校正和超速運(yùn)轉(zhuǎn)試驗(yàn)，故運(yùn)轉(zhuǎn)平穩(wěn)可靠。同一機(jī)號(hào)的通、引風(fēng)機(jī)葉輪，結(jié)構(gòu)相同，但材質(zhì)不同，一般來說通風(fēng)機(jī)選A3,引風(fēng)機(jī)選16Mn。2、機(jī)殼用普通鋼板焊接成蝸形體。單吸入風(fēng)機(jī)的機(jī)殼做成三種不同形式（N812機(jī)殼作成整體結(jié)構(gòu)，不能拆開，N1416機(jī)殼作成兩開式，N1829.5機(jī)殼作成三開式）。對(duì)引風(fēng)機(jī)，蝸形板作了適當(dāng)加厚，以防磨損。3、進(jìn)風(fēng)口收斂、流線型的進(jìn)風(fēng)

3、口制成整體結(jié)構(gòu)，用螺栓固定于風(fēng)機(jī)入口一側(cè)。4、調(diào)節(jié)門用來調(diào)節(jié)流量的裝置，軸向安裝于進(jìn)風(fēng)口之前。調(diào)節(jié)范圍由0度（全開）到90度（全閉）。調(diào)節(jié)門的搬把位置：從進(jìn)風(fēng)口方向看在右側(cè)，對(duì)右旋風(fēng)機(jī)，搬把由下往上推是由全閉到全開方向，對(duì)左旋風(fēng)機(jī)，搬把由上往下拉是由全閉到全開方向。5、傳動(dòng)傳動(dòng)部分的主軸由優(yōu)質(zhì)鋼制成，本風(fēng)機(jī)均采用滾動(dòng)軸承。軸承箱有兩種形式：Nq816用整體的筒式軸承箱；Nq1829.5用兩個(gè)獨(dú)立的枕式軸承箱。軸承箱上裝有溫度計(jì)和油位指示器（僅引風(fēng)機(jī)）。潤滑油采用30號(hào)機(jī)械油，加油量按油位標(biāo)示要求°N816整體筒式軸承箱如采用干油時(shí)，在軸承箱內(nèi)滾珠一側(cè)應(yīng)加擋油板，其固定槽予已制。引風(fēng)機(jī)

4、備有水冷裝置，因此，須加輸水管，耗水量隨氣溫不同而異，一般按0.51m3/h考慮。風(fēng)機(jī)的性能與選擇GY4-73型風(fēng)機(jī)只出給N10樣機(jī)的無因次性能表及曲線。由給出的無因次性能表或曲線可計(jì)算N8-28所有機(jī)號(hào)的有因次性能。由無因次參數(shù)計(jì)算有因次參數(shù)的公式為：Q=900nD2U0(m3/h)22Kp=plU2®2/l0l30023.5plU彳9J+1-1354550k丿P=pU2屮/Kp(Pa)12Pre二pinK(KW)耳mPin=程4000piu2九(KW)式中：P全壓（Pa）Q流量（ms/h）D2葉輪葉片外緣直徑（m）U2葉輪葉片外緣線速度（m/s）Kp全壓壓縮性系數(shù)Pin一內(nèi)功率（

6、80.8560.8280.794圖3管網(wǎng)特性和全壓偏差與流量關(guān)系流量過多或不足的處理：在使用時(shí)，常常發(fā)現(xiàn)流量過多或不足的現(xiàn)象。產(chǎn)生這種現(xiàn)象的原因很多，如在使用過程中流量發(fā)生時(shí)大時(shí)小的現(xiàn)象，主要由于管網(wǎng)中的阻力時(shí)大時(shí)小或風(fēng)機(jī)在飛動(dòng)區(qū)工作等緣故；如果是在使用過程中，經(jīng)過較長時(shí)間逐漸減少，或在短時(shí)間內(nèi)突然減少，則主要是由于管網(wǎng)堵塞。在新風(fēng)機(jī)安裝后，進(jìn)行運(yùn)轉(zhuǎn)時(shí)就發(fā)生流量過大或不足現(xiàn)象，其主要原因有下列幾點(diǎn)：(1) 管網(wǎng)阻力實(shí)際值與計(jì)算值相差過大。一般管風(fēng)特性方程式：P=KQ2,式中K阻力系數(shù)，如實(shí)際值K小于計(jì)算K,則流量增大，反之則流量減少。(2) 選擇時(shí)未考慮風(fēng)機(jī)本身全壓偏差A(yù)P影響，當(dāng)風(fēng)機(jī)實(shí)際全壓

7、為正偏差時(shí)，則流量增大，為負(fù)偏差時(shí)，則流量減少。在新風(fēng)機(jī)安裝后，開始正式運(yùn)轉(zhuǎn)時(shí)，或在使用過程中發(fā)生流量過大或過小時(shí)，可采用下列方法之一消除：(1) 利用調(diào)節(jié)門的開閉程度調(diào)節(jié)流量。(2) 改變風(fēng)機(jī)轉(zhuǎn)速調(diào)節(jié)流量。(3) 調(diào)換新的壓力較高或較低的風(fēng)機(jī)調(diào)節(jié)流量。(4) 改變管網(wǎng)阻力系數(shù)調(diào)節(jié)流量。必須指出的是：一般都采用節(jié)流裝置來調(diào)節(jié)流量，但當(dāng)實(shí)際流量比所需流量大得很多時(shí)，這種方法浪費(fèi)電力過多，很不經(jīng)濟(jì)，如條件允許，通常用降低風(fēng)機(jī)轉(zhuǎn)速或調(diào)換壓力較低的風(fēng)機(jī)。當(dāng)調(diào)節(jié)門全開時(shí)，流量仍嫌過小，此時(shí)應(yīng)設(shè)法減小管網(wǎng)阻力系數(shù)，以增加流量，亦可采用提高風(fēng)機(jī)轉(zhuǎn)速和調(diào)換壓力較高的風(fēng)機(jī)，但風(fēng)機(jī)的最大轉(zhuǎn)速不得超性能表之最高轉(zhuǎn)速

8、。風(fēng)機(jī)性能一般指在標(biāo)準(zhǔn)狀態(tài)下輸送空氣的性能。引風(fēng)機(jī)指定狀態(tài)為大氣壓力Pa=101300Pa,氣體溫度t=200°C，氣體密度p=0.745kg/ma。性能表中性能均指調(diào)節(jié)葉片為全開0度時(shí)。訂貨時(shí)以性能表為準(zhǔn)。當(dāng)實(shí)際使用狀態(tài)與上述指定狀態(tài)不符時(shí)，則必須把實(shí)際使用狀態(tài)的性能換算到指定狀態(tài)的性能，然后根據(jù)換算性能選擇風(fēng)機(jī)。其換算公式如下：Q=Qn°(m3/h)0np=p/n0、20P0jKL(Pa)PKp03Pin二Pin(巴)巴0(KW)nin=nin0式中：n一轉(zhuǎn)速（r/min）in內(nèi)效率，有注腳0為指定狀態(tài)，無注腳0為使用狀態(tài)安裝調(diào)試和操作在安裝前首先應(yīng)準(zhǔn)備好安裝所需的材料

9、及工具，并對(duì)風(fēng)機(jī)各部機(jī)件進(jìn)行檢查，對(duì)葉輪、主軸和軸承等更應(yīng)仔細(xì)檢查，如發(fā)現(xiàn)損傷，應(yīng)該修好，然后用煤油清洗軸承箱內(nèi)部。在安裝操作過程中必須注意下列幾點(diǎn)：1、在一些接合面上，為防生銹，減少拆卸困難，應(yīng)涂上潤滑脂或機(jī)油。2、在上接合面的螺栓時(shí)，如有定位銷釘、應(yīng)先上好銷釘再擰緊螺栓。3、檢查機(jī)殼內(nèi)及其它殼體內(nèi)部，不應(yīng)有掉入和遺留的工具或雜物。二）安裝要求1、按圖紙所示位置及尺寸安裝，為得到高效率特別要保證進(jìn)風(fēng)口與葉輪的間隙尺寸。2、保證主軸的水平位置，并測(cè)量主軸與電機(jī)軸的同心度及聯(lián)軸器兩端的不平行度。兩軸不平行允差為0.05mm，聯(lián)軸器兩端面不平行度允差為0.05mm。3、安裝調(diào)節(jié)門時(shí)，注意不要裝反，

10、要保證進(jìn)氣方向與葉輪旋轉(zhuǎn)方向一致4、風(fēng)機(jī)安裝后，撥動(dòng)轉(zhuǎn)子，檢查是否有過緊或與固定部分刮蹭現(xiàn)象。5、安裝風(fēng)機(jī)進(jìn)口出口管道時(shí)，重量不應(yīng)加在機(jī)殼上。6、全部安裝后，經(jīng)總檢合，方可試運(yùn)轉(zhuǎn)。（二）風(fēng)機(jī)的試運(yùn)轉(zhuǎn)1、風(fēng)機(jī)的試運(yùn)轉(zhuǎn)應(yīng)在無載荷（關(guān)閉進(jìn)氣管道閘門或調(diào)節(jié)門）情況下進(jìn)行。2、如運(yùn)轉(zhuǎn)情況良好，再轉(zhuǎn)入滿載荷（規(guī)定全壓和流量）運(yùn)轉(zhuǎn)。3、滿載荷運(yùn)轉(zhuǎn)，對(duì)新安裝風(fēng)機(jī)不少于2小時(shí)，對(duì)修理后的風(fēng)機(jī)不少于半小時(shí)（三）風(fēng)機(jī)的操作1、風(fēng)機(jī)啟動(dòng)時(shí)，應(yīng)做下列準(zhǔn)備工作：Q關(guān)閉調(diào)節(jié)門。Q檢查風(fēng)機(jī)各部的間隙尺寸，轉(zhuǎn)動(dòng)部分與固定部分有無刮蹭現(xiàn)象。©聯(lián)軸器應(yīng)加保護(hù)罩。Q檢查軸承的油位是否在最高與最低油位之間。©5點(diǎn)車
