從立式管道泵安裝技術(shù)上。另外吸水管道要求有嚴(yán)格的密封性，不能漏氣，漏水，否則將會破壞離心泵進(jìn)水口處的真空度，使離心泵出水量減少，嚴(yán)重時甚至抽不上水來。因此，要認(rèn)真地做好管道的接口工作，保證管道連接的施工質(zhì)量。提高管道泵本身抗氣蝕性能的措施（1）改進(jìn)管道泵的口至葉輪附近的結(jié)構(gòu)設(shè)計(jì)。增大過流面積；增大葉輪蓋板進(jìn)口段的曲率半徑，減小液流急劇加速與降壓；適當(dāng)減少葉片進(jìn)口的厚度，并將葉片進(jìn)口修圓，使其接近流線形，也可以減少繞流葉片頭部的加速與降壓；提高葉輪和葉片進(jìn)口分表面光潔度以減小阻力損失；將葉片進(jìn)口邊向葉輪進(jìn)口延伸，使液流提前接受作功，提高壓力。（2）采用前置誘導(dǎo)輪，使液流在前置誘導(dǎo)輪中提前作功，以提高液流壓力。

Thus to ensure the smooth operation of the pump, small vibration, low noise. Shaft seal using mechanical seal or mechanical seal combination, the use of imported titanium alloy sealing ring, medium high temperature resistant mechanical seal and the use of cemented carbide material, wear-resistant seal, can effectively extend the service life of mechanical seal. ISG Vertical pipeline centrifugal pump installation and maintenance is convenient, no need to disassemble the pipe road system, as long as the pump conjoined seat nut can be removed all the rotor parts. According to the requirements of use, that is, flow and lift needs to use the pump b, parallel operation mode. According to the requirements of the pipeline layout using the pump vertical and horizontal installation. ISG Vertical pipeline centrifugal pump for the transport of water and physical and chemical properties similar to the use of other liquids of clean water, suitable for industrial and urban water supply and drainage, high-rise building pressurized delivery, garden sprinkler irrigation, fire booster, long-distance transportation, HVAC refrigeration cycle, bathroom and other warm and cold water cycle booster and equipment matching, the use of temperature T<80℃. Because the water on too shallow water is in a flowing state, it will contain some air.
