進(jìn)口塑料磁力驅(qū)動泵(美國進(jìn)口品牌)
化工泵的密封裝置主要分兩類:
一類為靜密封,一類為動密封。靜密封通常有墊片密封、O型圈密封、螺紋密封等型式。動密封則主要有軟填料密封、油封密封、迷宮密封、螺旋密封、動力密封和機(jī)械密封等。
1、 O形圈密封
化工泵中常用的是橡膠O型圈。由于其形狀十分簡單,因而制造容易,成本低廉,不論O型圈的整體尺寸有多大,其截面尺寸都很小(只有幾毫米)所以重量輕,消耗材料少,使用方法簡單,安裝、拆卸方便,更為突出的優(yōu)點(diǎn)還在于O形圈具有良好的密封能力,使用范圍很寬。靜密封工作壓力可達(dá)100MPa以上,動密封也可達(dá)30Mpa。適用溫度為-60~200℃,可滿足多種介質(zhì)的使用要求。因此在泵的設(shè)計(jì)中得到越來越廣泛的應(yīng)用。
O形密封圈安裝在溝槽和被密封面之間,有一定壓縮量,由此產(chǎn)生的給予被密封的光滑面和溝槽底面以初始的壓縮應(yīng)力。從而起到密封作用。當(dāng)被密封的液體壓力增大時,O形圈的變形也隨之增大,從而傳遞給密封面的壓力也增大,密封的作用也增大。這就是O形密封圈具有良好密封能力的原因。
2、墊片密封
墊片是離心泵靜密封的基本元件,使用范圍非常廣泛。墊片的選型主要根據(jù)化工泵輸送介質(zhì)、溫度、壓力和腐蝕性等因素決定。
3、油封密封
是一種自緊式唇狀密封,其結(jié)構(gòu)簡單,尺寸小,成本低廉,維護(hù)方便,阻轉(zhuǎn)矩較小,既能防止介質(zhì)泄漏,也能防止外部塵土和其它有害物質(zhì)侵入,而且對磨損有一定的補(bǔ)償能力,但不耐高壓,
所以一般用在低壓場合的化工泵上。
4、螺紋密封
在化工泵上一般有兩種形式,一種是螺紋聯(lián)接墊片密封,一種是螺紋加填充濟(jì)密封,二者皆用于小直徑螺紋連接的密封場合。螺紋聯(lián)電動隔膜泵接墊片密
封的密封件是墊片,而螺紋只起提供壓緊力的作用。

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。同時這還意味著我們嘗試用深入的泵和系統(tǒng)知識以及優(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.
