在工業水處理過程中，為了加快曝氣速度，通常會采用羅茨鼓風機作為輔助設施，一臺功率強勁，噪音低的羅茨鼓風機無疑是最佳的選擇。羅茨鼓風機為容積式風機，輸送的風量與轉數成比例，三葉型葉輪每轉動一次由2個葉輪進行3次吸、排氣，與二葉型相比，氣體脈動變少，負荷變化小，機械強度高，噪聲低，振動也小，而且結構簡單，運轉平穩，已廣泛運用于包括水處理的眾多領域。

In the industrial water treatment process, in order to speed up the aeration velocity, usually by roots blower as auxiliary facilities, a strong power, low noise of Roots blower is undoubtedly the best choice. As the volume of Roots blower fan, air volume and speed proportional transportation, trefoil impeller rotating each time by 2 to 3 times the impeller suction, exhaust, compared with the two leaf type, gas pulsation is less, the load change is small, high mechanical strength, low noise, vibration small, simple in structure, smooth operation, has been widely used in many field of water treatment.

首先帶您回顧一下羅茨鼓風機的發展歷程，再了解幾款性能不錯的水處理用羅茨鼓風機產品。羅茨鼓風機個恒轉矩負載，其節電率與轉速降成正比即N％=△N％，雖然不同于一般羅茨鼓風機、水泵節電率更高，但因它的功率較大，而且只要爐墻不壞，是連續24小時工作的，并開動時間亦很長。因此節電潛力大，節電費用高。羅茨鼓風機進行技術改造后，改變了過去以調節出口（進口）閥門開度方式來調節風壓或風量的生產方式，勞動強度減輕，調節的及時性好，提高了產品的合格率，單耗明顯下降。變頻節能技術在水泥廠應用后不但節省了電費支出（節電率可達30％-50％），提高了產品質量，也增加了使用上的靈活性，對不同工藝性要求適應性更強。硬風特性決定了不允許通過關閉出風口或進風口的辦法來調節風量，而且經過采取優化以上主要工藝環節措施以后,羅茨鼓風機大量過剩風量調節只能采用旁路，造成風機能量的大量損耗，而且由于磨損而腐蝕問題突出，旁通閥門需要經常維修。羅茨風機主要由機殼、墻板及兩個裝有葉輪的轉子組成。通過一對同步齒輪的作用，使兩轉子呈反方向等速旋轉，并依靠葉輪與葉輪之間、葉輪與機殼之間的間隙，使吸氣腔和排氣腔基本隔絕，借助于葉輪旋轉、推動機殼容積內氣體，達到鼓風之目的。

First, take you to review the development of Roots blower, to understand a few good performance for water treatment of Roots blower products. Roots blower and a constant torque load, the energy saving rate and speed in direct proportion to the reduction of N%= △ N%, although in general different roots blower, pump power saving rate is higher, but because of its larger power, but as long as the furnace wall is not bad, is 24 hours of continuous work, and starting time is also very long. Therefore the potentiality of saving electricity, saving cost. Roots blower for technological transformation, changed the past to adjust the export (import) valve opening to regulate the pressure or volume of production, reduce the labor intensity, regulation, improve the qualified rate of products, consumption decreased significantly. Frequency conversion energy-saving technology in cement plant after application not only to save electricity costs (saving rate of 30%-50%), improve the quality of the products, also increased the flexibility of use, the adaptive ability for the different technique. Hard wind characteristics decided not allowed by closing the outlet or inlet measures to adjust the air volume, and through optimizing the above process measures, roots blower excess air volume adjustment can only use the bypass, a lot of loss caused by wind energy, but also due to wear and corrosion problems often need repair, bypass valve. Roots blower is mainly composed of a casing, wall panels and two with the impeller rotor. Through a pair of synchronous gears, so that the two rotors in opposite directions constant rotation, and rely on the clearance between the impeller and the impeller, impeller and casing, so that the suction chamber and exhaust chamber isolated basically, with the help of the impeller to rotate, push the gas cabinet volume, reaching the purpose of blast.第一、 請用戶在使用前認真地閱讀和消化產品說明書，并將產品說明書妥善保管。

第二、 開機前請一定要先打開手動放空閥, 檢查油箱機油是否已到油位線, 用手盤動風機是否靈活，如果盤動靈活,再按啟動, 然后慢慢將放空閥關閉,使風機達到滿負荷。關機時請一定也先打開放空閥, 然后再按斷開。這樣正常操作使用才能延長風機使用壽命。

第三、請每天派人檢查羅茨鼓風機齒輪油箱上的油位至少一次。如發現機油低于油位線, 需要馬上進行補充。如發現油標漏油則必須及時更換。 如發現放油塞漏油請將其擰緊，或者通過其他辦法阻止漏油現象。

第四、如果羅茨鼓風機的聯軸器或皮帶輪端使用機油潤滑，日常的操作事項和使用的機油的檢查方法同上。如果軸承是使用耐高溫油脂潤滑, 則每三個月至半年必須補充一次, 每年必須更換一次。

第五、 請確保風機房空氣流通順暢、降溫措施完備，羅茨鼓風機應盡量保持較低的進氣溫度，不可超過40 度。注意風機房的清潔工作，以免吸入灰塵太多堵塞進氣消聲器或卡死風機。

第六、注意電機溫升，當電機溫升太高時應該使用軸流風機直吹電機降溫。電機軸承應根據溫升及時進行檢查和加補軸承潤滑脂,以免燒壞軸承。

第七、在普通羅茨鼓風機正常運行時,皮帶輪或者聯軸器端軸承墻板溫度運行時55—75度,機身溫度55－85度,進氣溫度低于40度,出口溫度50—90度,齒輪油箱溫度55－85 度。這里提醒大家注意，羅茨鼓風機的參數不一樣，溫度也就不一樣，所以以上的數據僅供參考。

第八、需要定期檢查、調整羅茨鼓風機的皮帶張力，皮帶跳動幅度過大就必須進行調整或者更換。定期對電機底腳螺絲、風機底腳螺絲、底座螺絲進行緊固工作，這樣可以減輕風機震動。每年應對羅茨鼓風機進行一次保養，內容包括檢查風機軸承，齒輪是否磨損，風機油箱、氣腔、密封裝置是否需要清洗，以及校正風機各部位間隙等。
