產(chǎn)品詳情
在葉輪后蓋板上鉆若干個小孔,可減少葉輪兩側(cè)的壓力差,從而減輕了軸向推力的不利影響,但同時也降低了泵的效率。這些小孔稱為平衡孔。按吸液方式不同可將葉輪分為單吸式與雙吸式兩種,單吸式葉輪結(jié)構(gòu)簡單,液體只能從一側(cè)吸入。雙吸式葉輪可同時從葉輪兩側(cè)對稱地吸入液體,它不僅具有較大的吸液能力,而且基本上消除了軸向推力。根據(jù)葉輪上葉片上的幾何形狀,可將葉片分為后彎、徑向和前彎三種,由于后彎葉片有利于液體的動能轉(zhuǎn)換為靜壓能,故而被廣泛采用。離心泵的導(dǎo)輪為了減少離開葉輪的液體直接進(jìn)入泵殼時因沖擊而引起的能量損失,在葉輪與泵殼之間有時裝置一個固定不動而帶有葉片的導(dǎo)輪。導(dǎo)輪中的葉片使進(jìn)入泵殼的液體逐漸轉(zhuǎn)向而且流道連續(xù)擴(kuò)大,使部分動能有效地轉(zhuǎn)換為靜壓能。多級離心泵通常均安裝導(dǎo)輪。蝸牛形的泵殼、葉輪上的后彎葉片及導(dǎo)輪均能提高動能向靜壓能的轉(zhuǎn)化率,故均可視作轉(zhuǎn)能裝置。軸封裝置由于泵軸轉(zhuǎn)動而泵殼固定不動,在軸和泵殼的接觸處必然有一定間隙。為避免泵內(nèi)高壓液體沿間隙漏出,或防止外界空氣從相反方向進(jìn)入泵內(nèi),必須設(shè)置軸封裝置。

據(jù)器械包裝領(lǐng)域美國知名企業(yè)Bemis公司區(qū)負(fù)責(zé)人焦飛根據(jù)器械行業(yè)協(xié)會的數(shù)據(jù)統(tǒng)計(jì)分析,估計(jì)目前國內(nèi)總的市場容量應(yīng)在.5億美金左右。但事實(shí)是,器械包裝對大多軟包廠來說是個比較陌生的話題。在器械包裝領(lǐng)域,有專門研究產(chǎn)品設(shè)計(jì)的,有專門研究工藝的,卻鮮有專門研究產(chǎn)品包裝的。器械包裝現(xiàn)狀在一般情況下,器械產(chǎn)品的包裝是指產(chǎn)品的初包裝,即直接和產(chǎn)品接觸并構(gòu)成微生物阻隔屏障的部分;器械包裝的主要材料是塑料袋(PolyPouch)、吸塑成型膜(Form-FilledFilm)等。
