1、-污水泵站設(shè)計()摘要泵站是為水提供勢能和壓能,解決無自流條件下的排灌、供水和水資源調(diào)配問題的唯一動力來源,是解決洪澇災(zāi)害、干旱缺水、水環(huán)境惡化當(dāng)今三大水資源問題的有效工程措施之一。它們承擔(dān)著區(qū)域性的防洪、除澇、灌溉、調(diào)水和供水的重任,主要用于農(nóng)田排灌、城市給排水以及跨流域調(diào)水等。本次設(shè)計通過對流量的計算、揚程的估算,最終選取200WLI600-25立式泵,三用一備,配套電機型號為Y280M-2。經(jīng)核算后,其流量和揚程都能夠滿足設(shè)計要求。由于所選水泵為立式泵,故采用橫向排列布置。每臺水泵都配備單獨的吸水管路,管徑為350mm;每臺水泵也配有單獨的壓水管,管徑為300mm。兩條壓水管合
2、用一條出水干管,管徑為350mm。管材使用焊接鋼管,管道敷設(shè)采用明裝。采用集水池與機器間合建式的矩形泵站。經(jīng)計算集水池的長為5.95m,寬為4.2m;出水井的長為8m,寬為1.2米。在設(shè)計中,對泵房內(nèi)部的標(biāo)高進行了詳細的計算,確定了泵與泵之間的距離為2.0m,泵與電機之間的距離為2.5m,水泵距吸水管側(cè)墻3m,水泵距出水管側(cè)墻4m,在泵房右側(cè)設(shè)大門,水泵距大門的距離為5m。輔助設(shè)備選取了XWB-Ⅱ-2.5-3型機械格柵、YZ-60Z壓力表和SL型手動單梁起重機。最終確定了泵房檢修間的高度為6.37m,地下部分的高度為8.02m。--理論上,所設(shè)計內(nèi)容滿足《泵站設(shè)計規(guī)范》的要求,具有可
