進(jìn)口循環(huán)管道泵(美國進(jìn)口)
進(jìn)口循環(huán)管道泵選型:
1、循環(huán)管道泵的總流量不應(yīng)小于管網(wǎng)總設(shè)計(jì)流量,當(dāng)熱水鍋爐出口至循環(huán)管道泵的吸入口裝有旁通管時(shí),應(yīng)計(jì)入流經(jīng)旁通管的流量。
2、循環(huán)管道泵的流量-揚(yáng)程特性曲線,在水泵工作點(diǎn)附近應(yīng)比較平緩,以便在網(wǎng)路水力工況發(fā)生變化時(shí),循環(huán)管道泵的揚(yáng)程變化較小。一般單級水泵特性曲線比較平緩,宜選用單級水泵作為循環(huán)管道泵用。
3、循環(huán)管道泵的承壓、耐溫能力應(yīng)與熱網(wǎng)的設(shè)計(jì)參數(shù)相適應(yīng)。循環(huán)管道泵多安裝在熱網(wǎng)回水管上。循環(huán)管道泵允許的工作溫度,一般不能低于80℃。如安裝在熱網(wǎng)供水管上,則必須采用耐高溫的熱水循環(huán)管道泵。
4、循環(huán)管道泵的工作點(diǎn)應(yīng)在水泵高效工作范圍內(nèi)。
5、循環(huán)管道泵臺(tái)數(shù)的確定,與熱水供熱系統(tǒng)采用的供熱調(diào)節(jié)方式有關(guān)。循環(huán)管道泵的臺(tái)數(shù)不得少于兩臺(tái),其中一臺(tái)備用。當(dāng)四臺(tái)或四臺(tái)以上水泵并聯(lián)運(yùn)行時(shí),可不設(shè)置備用水泵,采用集中質(zhì)調(diào)節(jié)時(shí),宜選用相同型號(hào)的水泵并聯(lián)工作。
6、多熱源聯(lián)網(wǎng)運(yùn)行或采用*質(zhì)量-流量調(diào)節(jié)的單熱源供熱系統(tǒng),熱源的循環(huán)管道泵應(yīng)采用變頻調(diào)速泵。
7、當(dāng)熱水供熱系統(tǒng)采用分階段改變流量的質(zhì)調(diào)節(jié)時(shí),各階段的流量和揚(yáng)程不同。為節(jié)約電能,宜選用流量和揚(yáng)程不等的泵組。
8、對具有熱水供應(yīng)熱負(fù)荷的熱水供熱系統(tǒng),在非供暖期間網(wǎng)路流量遠(yuǎn)小于供暖期流量,可考慮增設(shè)熱水負(fù)荷用的循環(huán)管道泵。
9、當(dāng)多臺(tái)水泵并聯(lián)運(yùn)行時(shí),應(yīng)繪制水泵和熱網(wǎng)水力特性曲線,確定其工作點(diǎn),進(jìn)行水泵選擇。
進(jìn)口循環(huán)管道泵工作條件:
- 泵系統(tǒng)工作壓力為1.6Mpa,即泵吸入口壓力+泵揚(yáng)程≤1.6Mpa(泵系統(tǒng)工作壓力高于1.6Mpa時(shí),應(yīng)在訂貨時(shí)另行提出,以便在制造時(shí)泵的過流部件和聯(lián)接部采用鑄鋼。
2、輔送介質(zhì)為清水或物理化學(xué)性質(zhì)類似清水的其它液體(輸送介質(zhì)帶有細(xì)小顆粒時(shí),應(yīng)在訂貨時(shí)另行提出,以便裝配耐磨式機(jī)械密封)所輸送介質(zhì)中固體顆粒體積含量不超過單位體積的0.1%,粒度<0.2mm。
3、周圍環(huán)境溫度不超過40℃,海拔高度不超過1000m,相對濕度不超過95%。

我們會(huì)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(shí)。
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(huì)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(gè)人采取行動(dòng)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。
對建筑物進(jìn)行思考時(shí)的優(yōu)秀拍檔
思考建筑也意味著我們不僅把自己當(dāng)作泵的供應(yīng)商,而且還視為創(chuàng)造成功建筑的合作伙伴。同時(shí)這還意味著我們嘗試用深入的泵和系統(tǒng)知識(shí)以及優(yōu)異的智能泵來創(chuàng)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.
