  1. The local directional drilling is just staring in terrane, the equipments and the technologies ca n ' t satisfy far and far the spot construction needs, according to current circumstance and considing the existed equipments, the author put forward drilling by air hammer in terrane, having designed compounded - drilling tools, and recommended technology parameters. producing experiments have obtained good achievements in economic and in techniques

    國內定向鉆進鋪管技術在巖層只是剛剛起步,設備、工藝遠遠不能滿足現場施工需要,本文對國內、外巖層定向鉆進非開挖設備及工藝現,結合國內大多施工單位的已有設備,提出巖層空錘導向鉆進工法,設計了適合巖層鉆進的實用鉆具,並提出具有對性的工藝參數,生產性試驗取得了良好的經濟技術指標。
  2. Through the special studies on impacts to atomizing and humidifying effect from such factors as the firing pin type, centrifugal structure, higher spraying pressure, less aperture, initial water temperature and original state of the air, some conclusions are obtained, such as : the centrifugal nozzle with firing pin type, high pressure and little aperture has bigger air eddy and atomizing angle. the spaying liquid has high velocity. the droplet is small, and the heat and mass transfer velocity is high

    通過對撞型結構、離心式結構、較高的噴水壓力、較小的噴嘴徑、噴水初溫及待加濕空態對霧化加濕效果的作用原理的重點分析,得到:撞型高壓小徑離心式噴嘴具有較大的空渦與霧化角,噴出的液體流速高、液滴小、水與空傳熱傳質速率高,撞型結構提高了霧化加濕效率,高壓小徑的特點為霧化加濕提供了較大的能量,而噴水初溫的升高會減小水的粘性力和表面張力,從而優化加濕效果。
  3. As to the work about experiment study, at first, the paper makes certain the prominent affecting factors to the automating and humidifying property of this kind of nozzle by orthogonal experiment. by jicha analysis method and fangcha analysis method, the paper got that the nozzle aperture, the initial water temperature and the spraying pressure have prominent effect to the humidifying property while the effect of the original air state is small

    試驗工作方面,首先通過正交試驗確定對撞型高壓小徑離心式噴嘴霧化加濕性能影響顯著的因素,運用極差分析法和方差分析法,得到噴嘴徑、噴水初溫和噴水壓力對噴嘴的加濕性能影響顯著,而待加濕空態的影響相對較小。
