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 electromagic 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 houseIII目 錄第 1 章 .................................................................................................................................................................11 緒論 ..............................................................................................................................................................1 設(shè)計內(nèi)容 ..................................................................................................................................................1 設(shè)計題目： 蘇丹東卡哈拉主泵站的概念設(shè)計及主泵選型設(shè)計 ...................................................1 設(shè)計目的 ...........................................................................................................................................1 泵站設(shè)計水量 ： 32m3/s。 ...............................................................................................................2 設(shè)計任務(wù) ...........................................................................................................................................2 設(shè)計資料 ..................................................................................................................................................2第 2 章 計算說明書 ...........................................................................................................................................3 水泵和電機的初步選擇 ..........................................................................................................................3 泵站的組成及特點 ...........................................................................................................................3 泵站設(shè)計流量的確定 .......................................................................................................................4 管路總體布置及其設(shè)計 ...................................................................................................................4 泵站設(shè)計揚程估算 .........................................................................................................................7 初步選擇水泵和電機 .....................................................................................................................7 水泵安裝高程的校核 ............................................................................................................................11
