style="text-indent:25px">風(fēng)機(jī)動(dòng)葉卡澀，軸流風(fēng)機(jī)動(dòng)葉調(diào)節(jié)是通過傳動(dòng)機(jī)構(gòu)帶動(dòng)滑閥改變液壓缸兩側(cè)油壓差實(shí)現(xiàn)的。在軸流風(fēng)機(jī)的運(yùn)行中，有時(shí)會(huì)出現(xiàn)動(dòng)葉調(diào)節(jié)困難或完全不能調(diào)節(jié)的現(xiàn)象。出現(xiàn)這種現(xiàn)象通常會(huì)認(rèn)為是風(fēng)機(jī)調(diào)節(jié)油系統(tǒng)故障和輪轂內(nèi)部調(diào)節(jié)機(jī)構(gòu)損壞等。但在實(shí)際中通常是另外一種原因：在風(fēng)機(jī)動(dòng)葉片和輪轂之間有一定的空隙以實(shí)現(xiàn)動(dòng)葉角度的調(diào)節(jié)，但不完全燃燒造成碳垢或灰塵堵塞空隙造成動(dòng)葉調(diào)節(jié)困難。動(dòng)葉卡澀的現(xiàn)象在燃油鍋爐和采用水膜除塵的鍋爐比較普遍，解決的措施主要有：盡量使燃油或煤燃燒充分，減少碳黑，適當(dāng)提高排煙溫度和進(jìn)風(fēng)溫度，避免煙氣中的硫在空預(yù)器中的結(jié)露。在葉輪進(jìn)口設(shè)置蒸汽吹掃管道，當(dāng)風(fēng)機(jī)停機(jī)時(shí)對葉輪進(jìn)行清掃，保持葉輪清潔，蒸汽壓力＜＝0.2MPa，溫度＜＝200℃。適時(shí)調(diào)整動(dòng)葉開度，防止葉片長時(shí)間在一個(gè)開度造成結(jié)垢，風(fēng)機(jī)停運(yùn)后動(dòng)葉應(yīng)間斷地在0～55°活動(dòng)，北海風(fēng)機(jī)定做。經(jīng)常檢查動(dòng)葉傳動(dòng)機(jī)構(gòu)，北海風(fēng)機(jī)定做，適當(dāng)加潤滑油，北海風(fēng)機(jī)定做。風(fēng)機(jī)根據(jù)氣流進(jìn)入葉輪后的流動(dòng)方向分為：軸流式風(fēng)機(jī)、離心式風(fēng)機(jī)和斜流(混流)式風(fēng)機(jī)。北海風(fēng)機(jī)定做</p><div
