屏蔽泵結(jié)構(gòu)通常按泵冷卻潤(rùn)滑循環(huán)回路的形式定義。屏蔽泵型號(hào)按照不同的結(jié)構(gòu)也分為多種。
一、屏蔽泵結(jié)構(gòu)及屏蔽泵結(jié)構(gòu)圖
1、正循環(huán)屏蔽泵結(jié)構(gòu)
屏蔽泵正循環(huán)結(jié)構(gòu)也稱基本型結(jié)構(gòu)或稱普通型結(jié)構(gòu),如圖15-2所示,從泵體出口法蘭處設(shè)置引液管引入冷卻液,這種臥式屏蔽泵結(jié)構(gòu)用于輸送一般性非易汽化介質(zhì)。
當(dāng)輸送易汽化介質(zhì)時(shí),冷卻液經(jīng)后導(dǎo)軸承、屏蔽套、前導(dǎo)軸承回到葉輪進(jìn)口,冷卻液的溫度由低變高,部分冷卻液可能已汽化產(chǎn)生氣泡,帶氣泡的介質(zhì)進(jìn)入葉輪進(jìn)口將堵塞葉輪進(jìn)口流道,導(dǎo)致泵性能下降,嚴(yán)重時(shí)泵將出現(xiàn)斷流,冷卻液也就不能循環(huán)工作。所以,這種結(jié)構(gòu)適用于一般的非易汽化介質(zhì)的輸送。

2.逆循環(huán)屏蔽泵結(jié)構(gòu)
逆循環(huán)結(jié)構(gòu)也稱之為易汽化型結(jié)構(gòu),如圖15—3所示,從泵腔處引入高壓流體,一部分冷卻屏蔽套、后導(dǎo)軸承后,經(jīng)循環(huán)管獨(dú)立回到泵的人口罐的氣相部;另一部分冷卻液只冷卻前導(dǎo)軸承,回到葉輪進(jìn)口,這一部分冷卻液溫升極小,不至于出現(xiàn)汽化。因此,這種結(jié)構(gòu)適用于輸送易汽化介質(zhì)。

3.獨(dú)立循環(huán)屏蔽泵結(jié)構(gòu)
獨(dú)立循環(huán)結(jié)構(gòu)屏蔽泵如圖15—4所示,獨(dú)立循環(huán)結(jié)構(gòu)也稱之為高溫型結(jié)構(gòu)。
在泵轉(zhuǎn)輔上設(shè)置一輔助葉輪4,由輔助葉輪實(shí)現(xiàn)獨(dú)立循環(huán)工作。循環(huán)液由輔助葉輪出口經(jīng)過盤管流入底部潤(rùn)滑下導(dǎo)軸承、屏蔽套以及上導(dǎo)軸承,構(gòu)成循環(huán)回路。循環(huán)液盤管外部由一冷卻水套包覆,冷卻水套設(shè)有進(jìn)出管冷卻。輸送介質(zhì)與循環(huán)回路介質(zhì)幾乎不交換,使電動(dòng)機(jī)避免高溫工作。因此,這種結(jié)構(gòu)適用于輸送高溫介質(zhì)。
獨(dú)立循環(huán)屏蔽泵結(jié)構(gòu)圖:

4.多級(jí)葉輪屏蔽泵結(jié)構(gòu)
多級(jí)葉輪屏蔽泵結(jié)構(gòu)如圖15—5所示。圖15—為臥式多級(jí)結(jié)構(gòu),15—5b為立式多級(jí)結(jié)構(gòu),15-5c為兩端葉輪全對(duì)稱結(jié)構(gòu)。
多級(jí)葉輪屏蔽泵的葉輪通常均分左右兩部分,葉輪背靠背,實(shí)現(xiàn)軸向力平衡。與低比轉(zhuǎn)速同參數(shù)的單級(jí)葉輪相比,多級(jí)屏蔽泵比轉(zhuǎn)速大大增加,從而提高了泵的效率。許多高揚(yáng)程參數(shù)采用單級(jí)葉輪是無法實(shí)現(xiàn)的。
雙級(jí)葉輪全對(duì)稱屏蔽泵,屏蔽電動(dòng)機(jī)左右軸端各設(shè)置一個(gè)葉輪,轉(zhuǎn)子幾乎沒有軸向力,泵運(yùn)行平穩(wěn)、可靠。

5.微型屏蔽泵結(jié)構(gòu)
圖15—6所示是一種微型屏蔽泵。微型屏蔽電動(dòng)機(jī)有單相、三相兩種。微型屏蔽泵定子屏蔽套役有和定子焊死,是通過平墊壓緊的可拆結(jié)構(gòu)。轉(zhuǎn)軸是空心軸,循環(huán)液流經(jīng)屏蔽套從軸中心孔回到葉輪人口。該泵適用于家庭供水、增壓等。國(guó)內(nèi)生產(chǎn)的微型屏蔽泵大量出口到國(guó)外。
