進(jìn)口雙吸單級流程泵(美國進(jìn)口)

(1)啟動前的準(zhǔn)備工作

①檢查軸承箱內(nèi)潤滑油脂，加注太多反而因攪拌而發(fā)熱。若潤滑油不足時(shí)應(yīng)予補(bǔ)足。 ②檢查地腳螺栓等固定連接件有無松動，電機(jī)接地是否良好。

③盤泵，檢查泵軸是否轉(zhuǎn)動靈活，有無零部件相互摩擦的聲響。

④打開泵殼和吸入管路高點(diǎn)的放氣閥，利用吸入罐液位靜水壓力自流灌泵，或用真空泵引油灌泵，確認(rèn)泵殼和吸入管路中沒有氣體后關(guān)閉放氣閥。

⑤關(guān)閉泵的出口閥門，準(zhǔn)備啟動。

(2)啟動啟動電機(jī)，待排出管路上的壓力表達(dá)到額定值并穩(wěn)定后慢慢打開泵的出口閥，調(diào)整到所需工況。泵的空轉(zhuǎn)時(shí)間不宜太長，“以免密封環(huán)干摩擦生熱，—般以不超過1～2min 為宜。

(3)運(yùn)行離心泵穩(wěn)定運(yùn)行后要隨時(shí)觀察泵的真空表、壓力表和電氣系統(tǒng)的電流表，如果出現(xiàn)異常應(yīng)及時(shí)對其原因作出判斷，并采取相應(yīng)措施。如不見效，應(yīng)停泵做進(jìn)一步檢查。同時(shí)，要注意觀測軸封的泄漏情況，監(jiān)聽運(yùn)轉(zhuǎn)是否平穩(wěn)，有無不正常的聲音。

(4)泵的切換其操作步驟是，按泵的啟動方法啟動備用泵，緩慢打開備用泵出口閥，并保持短時(shí)間兩臺泵并聯(lián)運(yùn)行，待運(yùn)轉(zhuǎn)平穩(wěn)后緩慢關(guān)閉*臺泵的出口閥，然后停泵。泵的切換操作中，閥門的開啟或關(guān)閉都不能太快，以免引起水擊。

(5)停泵先緩慢關(guān)閉出口閥，然后切斷電源，再關(guān)閉進(jìn)口閥；待泵體溫度下降到室溫后，關(guān)閉冷卻水和封液閥門；后做好運(yùn)行記錄。

裝配順序

1、轉(zhuǎn)子組裝

(1) 葉輪應(yīng)裝在軸的正確位置上，不能偏向一側(cè)，否則會造成與泵殼的軸向間隙不均而產(chǎn)生摩擦。

(2) 裝上軸套并擰緊軸套螺母。為防止水順軸漏出，在軸套與螺母間要用密封膠圈填塞。組裝后應(yīng)保證膠圈被軸套螺母壓緊且螺母與軸套已靠緊。

(3) 將密封環(huán)、填料套、水封環(huán)、填料壓蓋及擋水圈裝在軸上。

(4) 裝上軸承端蓋和軸承，擰緊軸承螺母，然后裝上軸承體并將軸承體和軸承端蓋緊固。

(5) 裝上聯(lián)軸器。

2、吊入轉(zhuǎn)子

(1) 將前述裝好的轉(zhuǎn)子組件平穩(wěn)地吊入泵體內(nèi)。

(2) 將密封環(huán)就位后，盤動轉(zhuǎn)子，觀察密封環(huán)有無摩擦，應(yīng)調(diào)整密封環(huán)直到盤動轉(zhuǎn)子輕快為止。

3、扣泵蓋

將泵蓋扣上后，緊固泵結(jié)合面螺栓及兩側(cè)的軸承體壓蓋。然后，盤動轉(zhuǎn)子看是否與以前有所不同，若沒有明顯異常，即可將空氣管、密封水管等連接上，把填料加好，接著，就可以進(jìn)行對聯(lián)軸器找正了。

3、單吸雙吸離心泵安裝精度

這里給出的主要是聯(lián)軸器對中的精度要求。泵與電機(jī)聯(lián)軸器裝好后，其間應(yīng)保持2～3mm間隙，兩聯(lián)軸器的外圓上下、左右的偏差不得超過0.1mm，兩聯(lián)軸器端面間隙的大、小值差值不得超過0.08mm。

我們會對建筑物進(jìn)行審慎的思考，并藉此創(chuàng)造出懂得思考的建筑物 
阿卡迪亞商用建筑服務(wù)(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(jìn)行思考和重新審視，從而幫助客戶解決大大小小的挑戰(zhàn)。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(wǎng)絡(luò)工具和電子雜志藍(lán)圖(BLUEPRINT)，從中獲得產(chǎn)品優(yōu)先資訊和泵的相關(guān)知識。

準(zhǔn)備好迎接未來的挑戰(zhàn) 

商用建筑行業(yè)面臨著一系列的挑戰(zhàn)，這些挑戰(zhàn)將會重新定義未來數(shù)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(xiàn)有狀況。這意味著建筑物必須遵守嚴(yán)格的可持續(xù)發(fā)展標(biāo)準(zhǔn)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(jiān)理時(shí)間嚴(yán)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。

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.
