  1. Abstract : the paper introduces the brief cases of gas jet pump used for oil and gas well artificial lift, expounds operating mechanism, advantage and limitation of gas jet pump, analyses the actual results and service conditions of gas jet pump used for dewatering gas production wells. the analysis result shows the gas jet pump technology have the advantage of gas lift technology, and have higher efficiency and better result than semi - enclosed gas lift. service conditions of gas jet pump is the same with semi - enclosed gas lift. so it is worth using widely

    文摘:介紹國內外氣體射流泵用於油氣井人工舉升的簡況，闡述其作用機理、優點及局限性，分析用於排水采氣井的實際效果、應用條件；認為氣體射流泵工藝是具有氣舉工藝的優點，又比半閉式氣舉效率更高、效果更好，應積極推廣的工藝，因其應用條件與半閉式氣舉相同，故在氣舉井上作為接替工藝尤為簡便可行。
  2. With fast development of our country " s gas industry and air ' s increasingly serious contamination in city, using gas instead of coal and supplying energy in high efficiency and cleanliness has become necessary way in city. there are different problems in the current heating ( air conditioning ) systems. in the cogeneration system, heat and power affect each other, heating - pump heating ( aie conditioning ) system can not satisfy the peak load very well, the cost of gas fuel in boilor heating sestem is so high. the high generating efficiency of the diesel - engine two - sourse heating ( air conditioning ) systems is limited in range of 100kw - 1000kw, the heating scope is so limited. combined cycle of two sourse heating ( air conditioning ) system is most suitable selection to buesness community with big scope my paper aim at this syetem ' s primary question when it is applied in our country - - - - bringing project into execution and technology economy feasibility and off - design performence, combined with a certain demonstrating project in beijing buesness community, going along with calculating and analyzing, drawing out some efficient datas and conclusions, based on this, bringing out primary alements affecting combined cycle of two sourse heating ( air conditioning ) system " economics

    熱電聯產系統熱電相互牽連，熱泵供暖（空調）系統不容易很好地滿足尖峰負荷，鍋爐供暖系統供熱中天然氣燃料構成的成本過高，內燃機雙源供暖（空調）系統的高發電效率僅限於100kw - 1000kw負荷范圍，供熱面積有限。對于大面積的商業園區、居民小區，燃燒天然氣的燃氣-蒸汽聯合循環雙源供暖（空調）系統是最佳選擇之一。本論文針對該系統在我國應用時的主要問題- - -方案的技術實施與技術經濟可行性，結合北京某一商業園區示範工程，進行了系統的計算與分析，得到了有效的數據與結論，在此基礎上，提出影響聯合循環雙源供暖（空調）系統經濟性的主要因素，並進行敏感性分析，得出有益的結論；最後通過各種供暖方案的比較分析回答了某些人對該系統的疑慮和不解，並指出系統的優化方向。
  3. The conclusion is drawn that in the quasi two - stage compression heat pump system coupled with ejector, discharge temperature of the compressor is decreased effectively, electric power is reduced, and heating performance is increased compared with those of the flash - tank throttle system in the same conditions. it shows that the quasi two - stage compression heat pump system coupled with ejector improves performances of air - source heat pump in theory

    由結果可以看出:在相同工況下，準二級壓縮?噴射復合熱泵系統可以有效降低壓縮機排氣溫度，所消耗的電功率較閃發器節流系統有所降低，制熱性能有所增加，從理論上說明該系統在解決空氣源熱泵低溫適應性問題上有進一步突破。
  4. Abstract : as there were leak on contact place between shaft and rotor - body in built - up hollow rotor, dropping discharg gas speed of pump and efficiency applied of oil - sealed sliding vane rotary vacuum pump

    文摘:組合式空心轉子由於軸頭與轉子體之間的結合面存在著滲漏，使泵的抽氣效率性能下降，從而影響其在應用中的效率。
