Considering the electrovalence, the curve of water consumption and the reliability of water supply, this paper respectively sets up the model based on the maximal flux and the model based on the expectation flux. it takes yearly expenditure converting value and yearly cistern converting value as target function and takes continuity equation, velocity of flow and compression resistance of cast iron pipeline as restrictions and sets up the pga model on optimal design of water supply networks
考慮到峰谷電價、用水量變化曲線及用水可靠性因素的影響,分別建立了以最高時流量設計管網的模型和以期望時流量設計管網的模型,以年費用折算值加上清水池年造價折算值為目標函數,以連續性方程、管中流速和鑄鐵管耐壓值等為約束條件,進行并行遺傳演算法對給水管網優化設計的實現。Malleable iron threaded fittings of lining plastic for water supply
給水襯塑可鍛鑄鐵管件In recently years, application of new type plastic supply - drain pipe material gets more and more wide spread, it has great progress in our country for production and construction technique of many new type supply - drain pipe materials and component, and relevant material type from zinc - planting - corrugated pipe and iron pipe become to upvc, pp - r, pe - x, pb, pp - c and plastic - alumium, abs and so on
近年來新型塑料給排水管材在建築給排水中的應用越來越廣泛,我國的各種新型給排水管材、管件的生產技術和施工技術有了很大的發展,相應的材料種類也由鍍鋅鋼管、鑄鐵管變為upvc 、 pp - r 、 pe - x 、 pb 、 pp - c 、鋁塑復合管( pap ) 、 abs等等。In this article, through lab and engineering site trials that the physical data of new type pipe materials is corrected, the results are as follow : ( l ) the expansion coefficient of new plastic pipe materials is more large than that of iron pipe. ( 2 ) new plastic pipe materials have different heat - resisting character and according to the water temperature to choose pipe materials ; ( 3 ) the loss of head of water for new type pipe materials is more smaller than iron pipe and also correct the loss of head of water that calculated by theory ; ( 4 ) probing into the press - resistance character of new plastic pipe materials
本文通過試驗室試驗及工程現場試驗,對新型給排水管材的幾個重要的物理性能參數進行實驗測定,糾正了以往的錯誤認識。研究結果表明: ( 1 )新型塑料管材線脹系數遠遠大於鋼管和鑄鐵管,設計和施工中要嚴格考慮管道的伸縮; ( 2 )新型塑料管材耐高溫性能各不相同,需根據管內水溫選定管材; ( 3 )新型管材水頭損失遠小於鋼管,並對原水頭損失計算公式進行了修正; ( 4 )對于塑料管材的耐壓性能進行了探討。Specification for structural design of buried cast - ironpipeline of water supply and sewerage engineering
