1 PBG型屏蔽式管道離心泵產(chǎn)品概述
PBG屏蔽式管道離心泵實(shí)際上是電動(dòng)機(jī)加一層屏蔽,一方面減小機(jī)械噪音,一方面用水冷卻電動(dòng)機(jī)鐵芯(循環(huán)水從入口取出后進(jìn)入夾層流向出口),優(yōu)勢比較明顯。PBG型屏蔽式管道離心泵吸收了國際上屏蔽泵設(shè)計(jì)及制造的*技術(shù),將電機(jī)的屏蔽技術(shù)應(yīng)用于流體輸送領(lǐng)域,為適應(yīng)國內(nèi)市場需求而推出的系列化新產(chǎn)品。
PBG型屏蔽式管道離心泵系列性能參數(shù)基本符合國際標(biāo)準(zhǔn)IS02858及標(biāo)準(zhǔn)JB/T6878.2-93的規(guī)定。具有設(shè)計(jì)規(guī)范,通用化程度高,結(jié)構(gòu)合理,性能穩(wěn)定,運(yùn)轉(zhuǎn)低噪音,無振動(dòng)等顯著特點(diǎn),是替代常規(guī)臥式管道離心泵、立式管道離心泵的理想產(chǎn)品。PBG型屏蔽式管道離心泵全系列共67個(gè)品種,184個(gè)規(guī)格,其性能范圍:流量6.3~1080m3/h,揚(yáng)程12.5~125m,配用電機(jī)功率0.37~160kW,轉(zhuǎn)速1450r/min和2900r/min。

3 PBG型屏蔽式管道離心泵產(chǎn)品特點(diǎn)
2、泵進(jìn)出口設(shè)計(jì)成規(guī)格相同法蘭,且位于同一中心線上,可象閥門一樣直接安裝在管路上,且中心低,便于管道布置,安裝特別方便。
3、離心泵與電機(jī)同軸,軸向尺寸短,使泵運(yùn)行更加平穩(wěn),噪音低。
4、取消傳統(tǒng)軸封方式,避免了輸送介質(zhì)的外泄,因此具有*無泄露的顯著特點(diǎn)。
5、用滑動(dòng)軸承替代常規(guī)電機(jī)滾動(dòng)軸承,使泵具有運(yùn)行特別平穩(wěn),振動(dòng)噪音極低。
6、安裝檢修方便,無需拆動(dòng)管路系統(tǒng),只要拆下連接體螺母即可抽出全部轉(zhuǎn)子部件進(jìn)行檢查和維修。
7、可根據(jù)使用要求即流量和揚(yáng)程的需要進(jìn)行泵的串、并聯(lián)運(yùn)行方式。

9 PBG型屏蔽式管道離心泵安裝說明
2、如PBG屏蔽式管道離心泵用于輸送熱水液體時(shí),為了不使泵承受管路的熱變形,泵可以不固定底腳螺栓,當(dāng)管路系統(tǒng)在熱脹冷縮時(shí),使泵與管路同時(shí)移動(dòng)。
3、為了維修方便和使用安全,在泵的進(jìn)出口管路應(yīng)各裝上一只調(diào)節(jié)閥門及在泵進(jìn)出口附近各安裝一只壓力表,以保證在額定范圍內(nèi)運(yùn)行,確保泵的正常運(yùn)行和使用壽命。
4、PBG屏蔽式管道離心泵安裝前應(yīng)檢查機(jī)組緊固件有無松動(dòng)現(xiàn)象,泵體流產(chǎn)內(nèi)有無異物堵塞,以免水泵運(yùn)行時(shí)損壞葉輪和泵體。
5、PBG屏蔽式管道離心泵安裝時(shí)管路重量不應(yīng)加在水泵上,應(yīng)有各自的支承體,以免泵變形影響運(yùn)行性能和使用壽命。
