摘要可移動充氣式應急救護裝置是一種重點針對地鐵火災的新型消防搶險救援裝備,主要由風機、風管、救護站及其他輔助設備組成,其工作原理是採用機械通風的方式在救護站內建立正壓,阻止外界煙氣進入,從而在充滿煙氣的事故現場建立一個沒有煙氣的臨時安全場所。This new technology changes from the traditional method by which the induced and compressor wheel separately are designed and produced to a new one by which the one - piece compressor is designed. on the basis of this new technology and the optimum blade profile, the performance of both the compressor and the turbocharger is largely improved. through the heating power calculation of the compressor, the analysis of the surge and the block of the compressor, the test - bed performance test of the turbocharger, the matching test of turbocharger and diesel engine, the propulsion test of the turbocharger on plateau condition, it is proved that the newly - designed compressor not only has high efficiency, but also improves the flow distribution in the high efficiency area so that the propulsion line can run through the high efficiency area
主要內容包括:提出一種全新的壓氣機葉輪技術和概念,這種技術將傳統的導風輪和壓氣機分開設計、單獨加工改為整體設計、整體加工的單體葉輪;從增壓器與柴油機配機計算所得出的基本參數出發,通過對壓氣機進行熱力計算,確定壓氣機的基本結構參數;再對葉型以及葉輪輪廓與葉輪罩殼的配合間隙進行優化,對新設計的壓氣機進行喘振和堵塞分析;通過增壓器平臺性能試驗,驗證了新設計的壓氣機的性能水平得到了較大的提高,達到了提高增壓器的整體性能水平的目的;通過增壓器與柴油機配機試驗、以及增壓器用於高原條件下的牽引試驗,驗證了新設計的壓氣機不但具有高效率,還改善了高效率區的流量分佈,使牽引特性線貫穿高效率區。Starting from the frozen food and refrigeration principles and using comparative analysis method, we get conclusions that in the blow - frozen device, the open - mode, cold - quantity reclaim, low - press, direct - cooling air, absorbing - heat air cycle have the most significant reductions in food freeze dry cost, food hygiene, devices delicate, organizating air stream, non - electrical heat, high efficiency and safe refrigeration etc. the cold - cumulating and dryness tin is the equipment which applys the store - release characteristic of cold - cumulating stuff, ensures the higher efficiency of open - mode cold - quantity reclaim low - press direct - cooling air, shoulders conveyance of the saturated and frozen air to frozen storeroom to reduce dry cost of food and dry the cycling air to ensure safe and reliable
從食品冷凍和製冷原理入手,用對比分析方式得到了在吹風式凍結裝置中,開式回冷低壓直接冷卻吸熱循環空氣製冷機具有最大幅度降低食品凍結乾耗、確保食品冷凍安全、系統簡單、凍結庫小巧、氣流易於組織、無電機熱量、效率較高和製冷安全等結論。蓄冷乾燥器是通過蓄冷材料的蓄?釋冷特性,來保證開式回冷低壓直接冷卻吸熱循環空氣製冷機具有較高的效率,同時蓄冷乾燥器還擔負著輸送飽和低溫空氣至凍結庫以降低食品凍結乾耗和乾燥循環空氣以確保整機安全可靠工作的主要設備。Among these 62 stations, 24 are " full " stations from which measurements of winds, temperature, humidity, pressure and rainfall are made continuously by the field systems ; there are nine stations equipped with anemometers only ; another network of eight anemometer stations located in the airport areas is dedicated for the wind analyzer system for aircraft safety ; there is also a network of 21 rain gauge stations
