在工業(yè)水處理過程中，為了加快曝氣速度，通常會采用羅茨鼓風(fēng)機(jī)作為輔助設(shè)施，一臺功率強(qiáng)勁，噪音低的羅茨鼓風(fēng)機(jī)無疑是最佳的選擇。羅茨鼓風(fēng)機(jī)為容積式風(fēng)機(jī)，輸送的風(fēng)量與轉(zhuǎn)數(shù)成比例，三葉型葉輪每轉(zhuǎn)動一次由2個葉輪進(jìn)行3次吸、排氣，與二葉型相比，氣體脈動變少，負(fù)荷變化小，機(jī)械強(qiáng)度高，噪聲低，振動也小，而且結(jié)構(gòu)簡單，運(yùn)轉(zhuǎn)平穩(wěn)，已廣泛運(yùn)用于包括水處理的眾多領(lǐng)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(fēng)機(jī)的發(fā)展歷程，再了解幾款性能不錯的水處理用羅茨鼓風(fēng)機(jī)產(chǎn)品。羅茨鼓風(fēng)機(jī)個恒轉(zhuǎn)矩負(fù)載，其節(jié)電率與轉(zhuǎn)速降成正比即N％=△N％，雖然不同于一般羅茨鼓風(fēng)機(jī)、水泵節(jié)電率更高，但因它的功率較大，而且只要爐墻不壞，是連續(xù)24小時工作的，并開動時間亦很長。因此節(jié)電潛力大，節(jié)電費(fèi)用高。羅茨鼓風(fēng)機(jī)進(jìn)行技術(shù)改造后，改變了過去以調(diào)節(jié)出口（進(jìn)口）閥門開度方式來調(diào)節(jié)風(fēng)壓或風(fēng)量的生產(chǎn)方式，勞動強(qiáng)度減輕，調(diào)節(jié)的及時性好，提高了產(chǎn)品的合格率，單耗明顯下降。變頻節(jié)能技術(shù)在水泥廠應(yīng)用后不但節(jié)省了電費(fèi)支出（節(jié)電率可達(dá)30％-50％），提高了產(chǎn)品質(zhì)量，也增加了使用上的靈活性，對不同工藝性要求適應(yīng)性更強(qiáng)。硬風(fēng)特性決定了不允許通過關(guān)閉出風(fēng)口或進(jìn)風(fēng)口的辦法來調(diào)節(jié)風(fēng)量，而且經(jīng)過采取優(yōu)化以上主要工藝環(huán)節(jié)措施以后,羅茨鼓風(fēng)機(jī)大量過剩風(fēng)量調(diào)節(jié)只能采用旁路，造成風(fēng)機(jī)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(jīng)常維修。羅茨風(fēng)機(jī)主要由機(jī)殼、墻板及兩個裝有葉輪的轉(zhuǎn)子組成。通過一對同步齒輪的作用，使兩轉(zhuǎn)子呈反方向等速旋轉(zhuǎn)，并依靠葉輪與葉輪之間、葉輪與機(jī)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(zhuǎn)、推動機(jī)殼容積內(nèi)氣體，達(dá)到鼓風(fēng)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(rèn)真地閱讀和消化產(chǎn)品說明書，并將產(chǎn)品說明書妥善保管。
第二、 開機(jī)前請一定要先打開手動放空閥, 檢查油箱機(jī)油是否已到油位線, 用手盤動風(fēng)機(jī)是否靈活，如果盤動靈活,再按啟動, 然后慢慢將放空閥關(guān)閉,使風(fēng)機(jī)達(dá)到滿負(fù)荷。關(guān)機(jī)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(fēng)機(jī)使用壽命。
第三、請每天派人檢查羅茨鼓風(fēng)機(jī)齒輪油箱上的油位至少一次。如發(fā)現(xiàn)機(jī)油低于油位線, 需要馬上進(jìn)行補(bǔ)充。如發(fā)現(xiàn)油標(biāo)漏油則必須及時更換。 如發(fā)現(xiàn)放油塞漏油請將其擰緊，或者通過其他辦法阻止漏油現(xiàn)象。
第四、如果羅茨鼓風(fēng)機(jī)的聯(lián)軸器或皮帶輪端使用機(jī)油潤滑，日常的操作事項(xiàng)和使用的機(jī)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(bǔ)充一次, 每年必須更換一次。
第五、 請確保風(fēng)機(jī)房空氣流通順暢、降溫措施完備，羅茨鼓風(fēng)機(jī)應(yīng)盡量保持較低的進(jìn)氣溫度，不可超過40 度。注意風(fēng)機(jī)房的清潔工作，以免吸入灰塵太多堵塞進(jìn)氣消聲器或卡死風(fēng)機(jī)。
第六、注意電機(jī)溫升，當(dāng)電機(jī)溫升太高時應(yīng)該使用軸流風(fēng)機(jī)直吹電機(jī)降溫。電機(jī)軸承應(yīng)根據(jù)溫升及時進(jìn)行檢查和加補(bǔ)軸承潤滑脂,以免燒壞軸承。
第七、在普通羅茨鼓風(fēng)機(jī)正常運(yùn)行時,皮帶輪或者聯(lián)軸器端軸承墻板溫度運(yùn)行時55—75度,機(jī)身溫度55－85度,進(jìn)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(fēng)機(jī)的參數(shù)不一樣，溫度也就不一樣，所以以上的數(shù)據(jù)僅供參考。
第八、需要定期檢查、調(diào)整羅茨鼓風(fēng)機(jī)的皮帶張力，皮帶跳動幅度過大就必須進(jìn)行調(diào)整或者更換。定期對電機(jī)底腳螺絲、風(fēng)機(jī)底腳螺絲、底座螺絲進(jìn)行緊固工作，這樣可以減輕風(fēng)機(jī)震動。每年應(yīng)對羅茨鼓風(fēng)機(jī)進(jìn)行一次保養(yǎng)，內(nèi)容包括檢查風(fēng)機(jī)軸承，齒輪是否磨損，風(fēng)機(jī)油箱、氣腔、密封裝置是否需要清洗，以及校正風(fēng)機(jī)各部位間隙等。
