摘要

蘇丹東卡哈拉主泵站位于蘇丹尼羅河旁邊，設(shè)計此泵站總的提水量為32立方米每秒，設(shè)計過程中采用的是9臺立式斜流泵，8臺泵參與工作，一臺備用，每臺斜流泵的流量為4立方米每秒，選用與泵配套的電機是在長沙電機廠找得的一種YKK系列的大型三相異步電動機 。水泵采用的是單獨鋼管出水，直到出水池，水泵采用電動機直聯(lián)驅(qū)動。泵房采用水下樁基礎(chǔ)形式，水泵為濕坑進水形式，水泵直接放置于河水中從河里取水，所以設(shè)計的泵房為濕室型泵房。此泵站中設(shè)計的輔助設(shè)備有起重設(shè)備、計量設(shè)備、通風(fēng)設(shè)備和防水錘設(shè)備。采用的計量設(shè)備是電磁流量計，起重設(shè)備是QD型電動雙梁雙鉤橋式起重機，通風(fēng)設(shè)備是軸流通風(fēng)機，本泵站采用緩閉閥門來減少水錘的沖擊。

關(guān)鍵詞：泵站，立式斜流泵，電機，泵房

 

Su Dandong kahala pumping stations

Abstract:

Su Dandong hala pumping station next to the Nile in Sudan，Design the pump station in water yield is 32 cubic meters per second，Used in the process of design is 9 sets of vertical oblique flow pump，8 pump to participate in the work，A backup，Each oblique flow pump flow rate of 4 cubic meters per second，Selection of motor and pump matching is in changsha motor factory have to find a large YKK series three-phase asynchronous motor。Pump uses is separate steel pipe water, until out of the pool, water pump driven by motor straight league. Pump adopts the form of underwater pile foundation, the water pump is a wet pit water form, water pump placed directly on the river of water from the river, so the design of the pump room for wet room type pump room. This pump station in the design of auxiliary equipment lifting equipment, measuring equipment, ventilation equipment and water hammer. Is the electromagnetic flowmeter, measuring equipment used lifting equipment is QD type electric double double beam bridge crane, ventilation is axial flow blower, the pump station adopts gradual closing valve to reduce the impact of water hammer.

Key word：pump stations，vertical oblique flow pump，motor，pump house
