離心泵是鄂泉主要經(jīng)銷產(chǎn)品。
產(chǎn)品概述:
ISW型單級單吸臥式離心泵采用比較先進(jìn)的水力模型,根據(jù)IS型單級單吸離心泵之性能參數(shù)和立式泵的*結(jié)構(gòu)組合設(shè)計,
型號意義:
ISW系列臥式離心泵結(jié)構(gòu)圖:
ISW臥式清水離心泵安裝示意圖:
1、安裝前應(yīng)仔細(xì)檢查泵體流內(nèi)有無硬質(zhì)物,以免運(yùn)行時損壞葉輪和泵體。
2、安裝時管路理量不允許加在泵上,以免使泵變形,影響正常運(yùn)行。
3、擰緊地腳螺栓,以免起動時振動對泵性能產(chǎn)生影響。
4、在泵的進(jìn)、出口管路上安裝調(diào)節(jié)閥,在泵出口附近安裝壓力表,以控制泵在額定工況內(nèi)運(yùn)行,確保泵的正常使用。
5、排出管路如裝逆止閥應(yīng)裝在閘閥的外面。
6、泵的安裝方式分為硬性聯(lián)接安裝和柔性聯(lián)接安裝。
