進(jìn)口環(huán)流式潛水曝氣機(jī)美國進(jìn)口品牌
產(chǎn)品描述:
潛水曝氣機(jī)是經(jīng)過多年研制開發(fā)的新-代曝氣設(shè)備,它通過特殊結(jié)構(gòu)葉輪的高速旋轉(zhuǎn),在葉輪中心產(chǎn)生強(qiáng)大的負(fù)壓區(qū)從而吸入空氣進(jìn)入紊流室,水和空氣在紊流室及環(huán)流通道內(nèi)被強(qiáng)烈地剪切、粉碎、乳化,使空氣中的氧分子迅速擴(kuò)散到液相中去,形成第- -次溶氧;氣液混合物在大排量葉輪的作用下,通過環(huán)流通道向四周擴(kuò)散,帶動(dòng)污泥緩慢向上翻動(dòng),延長(zhǎng)了氣泡滯留時(shí)間,保證了氧氣的充分溶解于水中,形成第二次溶氧。該設(shè)備采用上進(jìn)水下排水,出水沿導(dǎo)流體圓周切線方向設(shè)計(jì),使整個(gè)池的水流動(dòng)形成一個(gè)立體大循環(huán),這樣就避免了剛擴(kuò)散到水中的氣液混合液被立刻吸入葉輪而降低溶氧效率,從而增加了物相接觸面,消除了整個(gè)池的死角,達(dá)到均勻曝氣的目的,同時(shí)提高了電機(jī)的冷卻效果,避免了機(jī)械密封與污水接觸,使設(shè)備的可靠性和壽命得到了*的提高。
潛水曝氣攪拌兩用機(jī)是在潛水曝氣機(jī)的基礎(chǔ)上,通過對(duì)電機(jī)和葉輪進(jìn)行改進(jìn)設(shè)計(jì),使其在同一臺(tái)設(shè)備上實(shí)現(xiàn)曝氣和攪拌兩種功能,在實(shí)際的應(yīng)用中,還可以通過控制系統(tǒng)自動(dòng)完成曝氣和攪拌功能,做到一機(jī)兩用,特別適用于OAO、MSBR等工藝。
另外,在上述兩種產(chǎn)品的基礎(chǔ)上,可通過增加風(fēng)機(jī),優(yōu)化系統(tǒng)結(jié)構(gòu),從而提高曝氣深度。
產(chǎn)品特點(diǎn):
1.充氧效率高,動(dòng)力效率可達(dá)到2.0~ 28kgO2/kw. h;
2.實(shí)現(xiàn)深水曝氣,二次溶氧,氣泡直徑小,比表面積大,氣、液、泥混合均勻,溶氧充分,處理效果好;
3.采用上進(jìn)水下排水設(shè)計(jì),電機(jī)的冷卻效果好,并使整個(gè)池的水流動(dòng)形成-個(gè)立體大循環(huán);
4.安裝方便靈活,根據(jù)需要可采用固定安裝和浮動(dòng)安裝等多種安裝方式(見安裝方式);
5.不受池型大小限制,可根據(jù)開氧量配置機(jī)型,可-池一機(jī),也可-池多機(jī)。
6.電纜出線采用了特別結(jié)構(gòu),排除了因人為拉扯、電纜外套破碎、電纜老化等偶然因素導(dǎo)致的漏水、漏電、短
路、定子線團(tuán)燒毀,有效地降低了整機(jī)上部進(jìn)水出現(xiàn)故障的概率。
7.考慮到潛水曝氣機(jī)在啟動(dòng)和運(yùn)行時(shí)可能發(fā)生的狀況,內(nèi)置了多項(xiàng)預(yù)警傳感器,包括有接線室、電機(jī)腔和油室
腔內(nèi)滲漏、上下軸承和電機(jī)線圈溫升。在外置控制柜中有缺相、短路、過流及水位控制等保護(hù)。
8.潛水曝氣機(jī)使用了三只軸承,上端用帶密封蓋的自潤(rùn)滑軸承,下端用一只向心推力軸承,一只滾珠軸承,結(jié)
構(gòu)上保證了全部軸承在有效潤(rùn)滑條件下運(yùn)行,提高了軸承和機(jī)械密封的壽命,降低了泵的振動(dòng)和噪音。
9.產(chǎn)品應(yīng)用了雙密封式結(jié)構(gòu)。
※外傳統(tǒng)產(chǎn)品:在葉輪與電機(jī)之間只有一個(gè)油室,因機(jī)械密封是泄漏的,特別是新機(jī)械密封在磨合期內(nèi)
泄漏量還較大,污水通過*道機(jī)械密封進(jìn) 入油室后,在機(jī)械密封的旋轉(zhuǎn)作用下,形成油水混合物,油水混合物通過
第二道機(jī)械密封就進(jìn)入到軸承室和電機(jī)室中,由于電機(jī)室軸承處的溫度較高,將油中的水蒸發(fā)出來,使電機(jī)繞組的
絕緣下降。當(dāng)水汽達(dá)到一定濃度時(shí),還會(huì)形成凝露.嚴(yán)重威脅電機(jī)的安全運(yùn)行。同時(shí),污水還全使軸產(chǎn)生銹蝕,破壞
軸承的精度,使泄漏量增大,產(chǎn)生惡性循環(huán),雖然油室中有油水探頭,那只是當(dāng)水進(jìn)到相當(dāng)程度后才能發(fā)出報(bào)警信
號(hào)。
※雙密封室產(chǎn)品:雙密封室,靠電機(jī)的是油室,靠葉輪的是空氣緩沖密封室。油室中是二個(gè)獨(dú)立的機(jī)
封,葉輪處還有-道機(jī)封,總共有三道機(jī)械密封。這種結(jié)構(gòu)有以下兩大突出優(yōu)點(diǎn):
a、水從葉輪后的第- -道機(jī)封進(jìn)入空氣緩沖密封室中,空氣體積減少壓力上升,到一定程度即形成平衡,有效
阻止了污水的泄漏。而且緩沖密封室中裝有水探測(cè)傳感器,緩沖室中的水滿至85%體積時(shí),即發(fā)出報(bào)警。
b、油室*不與水接觸,保證了電機(jī)的安全。因水無法進(jìn)入油室,油室中的機(jī)封工作環(huán)境較好,密封效果
好,壽命長(zhǎng)。
C、維護(hù)簡(jiǎn)便、費(fèi)用低:
機(jī)械密封是潛水曝氣機(jī)中易損壞的零件之一,傳統(tǒng)產(chǎn) 品更換機(jī)封時(shí)必須打開油室,由于污水進(jìn)入了油室,會(huì)在
軸及密封處形成水垢,這給維護(hù)修帶來*的麻煩。由于現(xiàn)場(chǎng)條件的限制,無法進(jìn)行必要的氣密試驗(yàn)很難修好。由
于油室泄漏對(duì)電機(jī)有*的破壞作用,因此有些用戶不得不將產(chǎn)品運(yùn)到生產(chǎn)廠^維修,費(fèi)用很高。
雙密封室結(jié)構(gòu)*消除了這一-煩惱。因?yàn)橹挥信c污水接觸的機(jī)封才容易損壞,一般只需對(duì)葉輪后的*道機(jī)
封進(jìn)行更換,油室中的機(jī)封很少更換。油室中沒有污水、水垢等雜物,維修恢復(fù)較容易。即使發(fā)生泄漏,水升至
探測(cè)傳感器位置時(shí),電柜立刻報(bào)警,采用有效措施污水無法進(jìn)入油室。
產(chǎn)品適用范圍
本產(chǎn)品可廣泛應(yīng)用于市政、石油、化工、印染、制藥、制革、食品、造紙、紡織等行業(yè)的污水處理,也可對(duì)江
河、湖泊、養(yǎng)殖等進(jìn)行復(fù)氧和水質(zhì)凈化。

We will think carefully about buildings and create thinking buildings
Arcadia commercial building services (CBS) relies on the concept of in-depth thinking of buildings. Our mission is to constantly think about and re-examine the building, so as to help customers to solve the big and small challenges. Therefore, we need to provide consulting engineers around the world with tools that can make their work faster and easier. Every day, consulting engineers can easily access our network tools and blueprint to obtain product priority information and pump related knowledge.
Be ready for the challenges of the future
The commercial construction industry is facing a series of challenges that will redefine the way we think about architecture in the next few years.
At the macro level, global climate change calls on all of us to take action to change the current situation. This means that buildings must adhere to strict sustainable development standards to maintain low energy consumption and high flexibility. At the micro level, consulting engineers are faced with the problem of many projects and insufficient supervision time. Therefore, it is very important to get correct information quickly and conveniently.
Excellent partner when thinking about buildings
Thinking about architecture also means that we see ourselves not only as suppliers of pumps, but also as partners in creating successful buildings. At the same time, it also means that we try to create buildings with in-depth pump and system knowledge as well as excellent intelligent pumps.
