進口多級泵(美國進口)
結構說明：
1、泵殼體部分
泵殼體部分主要由軸承、前段、中段、后段、導葉等用螺栓聯接成整體，前段吸入口中線呈水平線，后段吐出口中線與水平垂直。
2、轉子部分
轉子部分主要由軸承及安裝在軸上的葉輪、軸套、平衡盤等零件組成。軸上零件用平鍵和軸套螺母緊固使之與軸成為一體。整個轉子由兩端軸承支承在泵殼體上，轉子部分的葉輪數目是根據泵的級數而定。
3、軸承部分
本泵軸承有滑動軸承和滾動軸承兩種，按型號不同而定，均不承受軸向力。泵在運行中應當允許轉子部分在泵殼體中軸向游動，不能采用向心軸承。
4、泵的密封
泵的前段、中段、后段之間密封面均采用二硫化鉬潤滑脂密封，轉子部分與固定部分之間靠密封環、導葉套、填料密封，當密封環和導葉套的磨損程度已影響泵的工作和性能時應予及時更換。
5、平衡機構
平衡機構由平衡環、平衡盤、平衡套等組成，平衡機構用于平衡泵的軸向力。 成套供應泵，防爆電機、公用底座或本身底座、止回閥、閘閥和備件。
性能特點：
1）節能：采用*的水力模型，自主研發節能產品；由于泵轉子沒有了平衡盤的磨損及軸向脈動，葉輪與導葉的對中性總是處于好狀態，不會像普通多級泵結構隨平衡盤的磨損、轉子部件前移而出現效率明顯下降；且沒有了平衡水的泄露，減少了容積損失，在整體上提高了泵的運行效率，降低了軸功率，比普通多級泵效率平均高2%-3%；
2）新結構：具有對稱布置的葉輪轉子部件，各級對稱葉輪所產生的軸向力相互抵消，無需采用平衡盤結構就能實現泵腔內巨大軸向推力的自動平衡，突破了多級泵的傳統結構；
3）新技術：*的節流、減壓裝置，奇數級平衡裝置，還能起到輔助支承作用；
4）高可靠性：葉輪的對稱布置，使運行中產生的軸向推力基本得到自相平衡，從而不需要小間隙、高壓降、易沖刷、易磨損、易出故障的平衡盤裝置，使軸向力載荷對泵的磨損和對系統干擾的不利影響降到小。殘余軸向力由推力軸承承受，這樣使泵軸始終處于受拉狀態、軸的受力狀態均勻，且應力峰值較原型結構大大降低，從而提高了泵轉子的剛性和臨界轉速，使泵轉子運行的平穩性和可靠性顯著提高；
5）汽蝕性能好，使用壽命長：優化的水力及結構設計、精密的鑄造、可靠的耐磨材質，部分型號泵首級葉輪采用雙吸結構，使泵具有良好的抗汽蝕性能，整機運轉平穩、噪音低、使用壽命長；
6）機封強可靠性：泵啟、停時轉子部件沒有軸向竄動，工作時沒有軸向脈動，克服了一直困擾多級泵的機封可靠性差這一難題；
7）應用廣泛：取消了小間隙平衡盤，比傳統多級泵結構適應介質性質更為惡劣的場合；

我們會對建筑物進行審慎的思考，并藉此創造出懂得思考的建筑物
阿卡迪亞商用建筑服務(CBS)賴以生存的理念在于對建筑物的深入思考。我們的使命是不斷對建筑進行思考和重新審視，從而幫助客戶解決大大小小的挑戰。所以，我們要為*咨詢工程師提供能夠使其工作更迅速輕松的工具。每天咨詢工程師可以輕松訪問我們的網絡工具和電子雜志藍圖(BLUEPRINT)，從中獲得產品優先資訊和泵的相關知識。
準備好迎接未來的挑戰
商用建筑行業面臨著一系列的挑戰，這些挑戰將會重新定義未來數年我們對于建筑的思考方式。
宏觀上看，*氣候變化呼吁我們每個人采取行動來改變現有狀況。這意味著建筑物必須遵守嚴格的可持續發展標準以保持低能耗和高靈活性。微觀處，咨詢工程師們卻面臨著工程多，監理時間嚴重不足的難題。因此，快速方便地獲取正確的信息顯得尤為重要。
對建筑物進行思考時的優秀拍檔
思考建筑也意味著我們不僅把自己當作泵的供應商，而且還視為創造成功建筑的合作伙伴。同時這還意味著我們嘗試用深入的泵和系統知識以及優異的智能泵來創建建筑。

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.
