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。

曝氣技能按流體運動性質(zhì)分類,由分類的區(qū)別能夠進(jìn)一步知道下面兩個疑問。1氣相和液相的自動運動與被迫觸摸氣相與液相兩種流體相混,究竟是讓哪一種流體自動運動為好?若是技能上無特殊要求,那就只要一個動能作用的目標(biāo)疑問;一類是制作水躍(重質(zhì)液相自動運動,輕質(zhì)氣相是被迫觸摸),另一類是制作升泡(輕質(zhì)氣相自動運動,重質(zhì)液相是被迫觸摸)。因為液相流體與氣相流體兩者質(zhì)量相差近千倍,其機械運動損耗的區(qū)別是清楚明了的。
