軸向式葉輪 的英文怎麼說
中文拼音 [zhóuxiàngshìyèlún]
軸向式葉輪
英文
axial impeller-
In this axial turbine, steam always flows along the axis of rotated axis, thus, all blades extend with the radiation shape along the axis outward
在這種軸流式渦輪機中，蒸汽總是沿主軸的旋轉軸流動的，因此，葉片由主軸向外呈輻射狀展開。To ensure the charging pump working reliably, the following measures should be adopted : ( 1 ) adopting modified circular casing to reduce the radial force of the impeller and decrease the seal clearance ; ( 2 ) using radical ribs on impeller and helical sealing on shaft to realize minor pressure differential ; ( 3 ) using back pressure stuffing box to ensure sealing under small packing force ; ( 4 ) adopting self - lubricant flexible graphite stuffing for absorption of solids entering in the graphite in case of leaking
為確保灌注泵可靠工作，提出改進措施： （ 1 ）採用改型環形泵體降低葉輪的徑向力，減小軸封間隙，抑制泄漏； （ 2 ）採用背葉片降低葉片根部壓頭，獲得微壓，使軸封兩端承受較小壓差； （ 3 ）採用螺旋密封降低軸封兩端壓差，在保持微壓的同時避免出現負壓，密封效果更好； （ 4 ）採用反壓式填料密封結構，在很小的壓緊力下，即可保證密封； （ 5 ）採用具有潤滑功效的柔性石墨填料，即使發生軸封泄漏，進入石墨內部的固相顆粒也將隨著石墨的消耗而被鉆井液吸收。Urbular turbine generator set is suitable for heads from 2m to 15m and large discnarge. its feature is that water flow is axial throughout the passage from the inlet to the outlet, so that the passage is straight conduit essentially. the tubular turbine generator set is characterized by good characteristic of water flow and high efficiency. etc
混流式水輪發電機組廣泛適用於高中低各種水頭，一般從10米至300米，其特點是水流流經轉輪葉片時先沿著幅向進入，然後逐漸變成軸向離開，因而混流式水輪發電機組具有運行可靠，結構簡單，平均效率較高等特點。
