水泥倉頂除塵器除塵濾芯的維護與保養(yǎng)
一、經常檢查除塵器的運轉情況，特別是剛開始的幾個星期。
注意：以下事項檢查至少應該在六個月內完成一次。
1、檢查振動電機。
2、檢查開始濾芯。
3、檢查外部密封及卡箍。
4、每天根據除塵情況，即使按動振動電機的按鈕，使附著的濾芯上的粉塵脫落。
二、水泥倉頂除塵器清洗及更換濾芯。
1、取下頂蓋（輕拿輕放），拆下振動電機座，使用專用扳手（隨機）取消濾芯，清洗或更換。重復安裝濾芯時，反順序重復操作。
| 序號 | 故障 | 檢查方法 | 處理措施 |
| 1 | 濾芯堵塞 | 1、檢查濾芯是否損壞 2、檢查密封盒包裝 | 1、更換濾芯 2、更換密封件 |
| 2 | 清潔區(qū)域出現(xiàn)灰塵 | 檢查振動電機的安裝是否正確 | 正確安裝振動電機 |
水泥倉頂除塵器技術特點:
1、內部采用脈沖專用褶式濾筒,結構緊湊,節(jié)省占地空間。 2、濾筒采用一體化設計，密封性好，方便安裝更換，縮短停車時間。 3、超高過濾效率，對平均粒度0.5微米粉末，過濾效率可達99.99%。 4、節(jié)省壓縮空氣用量，與常規(guī)脈沖除塵器相比，噴吹壓力可降低20%。 5、濾筒密閉安裝形式更趨科學化，用戶可根據場合，選擇應用頂裝式或底裝式濾筒.
水泥倉頂除塵器使用方法：
1、每次動轉水泥倉上料時進氣壓力不準超過0.1-0.15（MPa）否則壓力過高會將濾芯折彎，水泥倉一定要安裝料位計，防止灰滿時將濾芯折彎。水泥倉上料完畢后，啟動振動電機除塵。電機振動3分鐘關閉。2、每兩到三個月時間，將取下，使用干燥壓力空氣將濾芯反吹，清理，提高濾芯的過濾能力。3、一般在除塵器出廠前都做了彈簧的振動調整，每次拆裝時一定要保證予緊力。
水泥倉頂除塵器是一種圓形可拆的金屬濾筒，底板上有14個嵌入圓形孔，它設有14個濾芯，扎緊在上端1個振動器的吊架上，定時震動，使濾芯阻留下來的灰塵降落在倉內。
近年來水泥倉頂除塵器應用越來越廣，增加了倉頂除塵器的了解，水泥倉頂除塵器的主要配件我們基本上都知道其作用，卡箍是我們不太了解的配件，下面我為大家介紹一下卡箍的作用。
水泥倉頂除塵器圓筒主要分成三節(jié)，這三節(jié)都是需要卡箍連接的，沒有它就不能把除塵器這三部分連接到一起，卡箍還起到防止漏灰的作用，灰塵容易通過縫隙出來，造成環(huán)境污染，是用卡箍能防止這種現(xiàn)象的發(fā)生。倉頂除塵器每個配件都有它不可忽視的作用，我們應該重視。
