是一種適用于開發(fā)廣大平原、丘陵、沿海等低水頭、大流量水力資源，經(jīng)濟(jì)加值較高的機(jī)型。該機(jī)型過流能力大，高效區(qū)廣，它與立式軸流式機(jī)組相比，效率高，廠房開挖量小，電站水工投資能節(jié)省10％－20％。
Tubularturbine is the type one of high economicvalues and is preferable to some plains,hills and coastal areas of low head and large discharge. This kind ofunits has the characteristics of high flow capacity, and broad section of high hydraulic efficiency, especially, it hasthe advantages of higher efficency and less excavation quantities and saving10%~20% cost of hydraulic structure compared with vertical Axial turbine.
貫流式水輪機(jī)適用于低水頭、大流量電站，適用水頭2~25m。按其結(jié)構(gòu)型式分為燈泡式、軸伸式、豎井式和全貫流式等。
Tubular turbines are suitable for low head and largedischarge. Theusing head can be 2 to 25 meters.They can be classified into Bulb,S-type,.Pitand strafslo turbines according to The arrangement and structure of the units.
