葉輪保養:在葉輪運轉初期及所有定期檢查的時候,只要一有機會,都必須檢查葉輪是否出現裂紋、磨損、積塵等缺陷。

軸承保養:經常檢查軸承潤滑油供油情況,如果箱體出現漏油,可以把端蓋的螺栓擰緊一點,這樣還不行的話,可能只好換用新的密封填料了。

如果要對風機軸承作更換,應注意以下事項:在將新軸承裝入前,必須使軸承與軸承箱都十分清潔。將軸承置于溫度約為70~80℃的油中加熱后再裝入軸上,不得強行裝配,以避免傷軸。

其余各配套設備的維修保養:各配套設備包括電機、電動執行器、儀器、儀表等的維修保養詳見各自的使用說明書。這些使用說明書都由各配套制造廠家提供,本制造廠將這些說明書隨機裝箱提供給用戶。

假設風機工作在A點效率最高,此時風壓為H2,風量為Q1,軸功率N1與Q1、H2的乘積成正比,在圖中可用面積AH2OQ1表示。如果生產工藝要求,風量需要從Q1減至Q2,這時用調節風門的方法相當于增加管網阻力,使管網阻力特性變到曲線(3),系統由原來的工況點A變到新的工況點B運行。從圖中看出,風壓反而增加,軸功率與面積BH1OQ2成正比。顯然,軸功率下降不大。如果采用變頻器調速控制方式,風機轉速由n1降到 n2,根據風機參數的比例定律,畫出在轉速n2風量(Q-H)特性,如曲線(4)所示。可見在滿足同樣風量Q2的情況下,風壓H3大幅度降低,功率N3隨著顯著減少,用面積CH3OQ2表示。節省的功率△N=(H1-H3)×Q2,用面積BH1H3C表示。顯然,節能的經濟效果是十分明顯的。

(1)鍋爐風機的變頻節能改造:鍋爐的變頻節能改造通常是指對鍋爐風機的變頻節能改造。

鍋爐風機在設計時是按最大工況來考慮的,在實際使用中有很多時間風機都需要根據實際工況進行調節,傳統的做法是用開關風門、閥門的方式進行調節,這種調節方式增大了供風系統的節流損失,云南通風管告訴您在啟動時還會有啟動沖擊電流,且對系統本身的調節也是階段性的,調節速度緩慢,減少損失的能力很有限,也使整個系統工作在波動狀態;而通過在鍋爐風機上加裝變頻調速器(裝置)則可一勞永逸的解決好這些問題,可使系統工作狀態平緩穩定,并可通過變頻節能收回投資。鍋爐的變頻改造方案一例如下:鍋爐風機的裝機概況:2×75KW,1×55KW。

(2)投資與節能:變頻節能系統(裝置)在各類調速系統中使用時其節能效果對于單臺設備可做到20-55%,在風機這類設備的一般應用的節能效果平均也可做到20-50%,在未受到其它因素的影響的情況下一般可取平均值,這些節能效果平均值是由實際應用中得到,權威性數據可由市場上公開出售的資料(書)查到;通過這些數據再進行一些簡單的投資回收率的計算可知:變頻節能系統(裝置)的投資回收期一般為6-15個月(這是經驗值也是權威數據)
