氣動波阻 的英文怎麼說
中文拼音 [qìdòngbōzǔ]
氣動波阻
英文
aerodynamic wave drag-
This paper analyzed the mechanism that gas and liquid flow through the holes according to the fluid characteristics of the compound tray, and put forward that there are three states of liquid flowing, gas flowing and blocked for the holes because of the foam fluctuating on the tray while the compound tray operates
本文根據復合塔板的氣液流動特點，分析了氣液穿孔流動的機理。根據前人的研究結果，提出復合塔板在操作時，由於泡沫層的波動，其篩孔存在通氣、通液和阻塞三種狀態。Temperature kits : contact must be properly fixed in the evaporator export pipelines, real - time communication evaporator components to temperature degrees, the material will be filled through interlinked capillary pressure due to the expansion of corrugated boxes ; swelling corrugated boxes on the pressure for change in the thrust pole with an adjustment screw and spring - loaded ball - type valves to adjust the resistance of the degrees of refrigeration volume precision adjustments
感溫包：是必須妥善接觸固定在蒸發器的出口管道上，感知蒸發器實時回氣溫度的部件，它將充填物質的熱脹冷縮壓力通過相通的毛細管提供給膨脹波紋箱；膨脹波紋箱依據壓力的變化推動推力桿結合過熱度調整螺絲和彈簧的阻力來調整球型閥的開度，實現製冷量的精確調整。The state of the holes changes continuously along with the moving waves
隨著波的運動，處于通液、通氣和阻塞狀態的篩孔不斷變化。When the temperature to gas pipelines, temperature packets of material expansion, the pressure rise, inflation pressures are rising corrugated box, corrugated promote the expansion thrust to overcome the spring - loaded pole resistance, the ball - type valve opened for big change ; when the gas pipeline to reduce the temperature, temperature of the material swelling up, the pressure lowered inflation corrugated box pressure also reduced, spring - loaded pole compressed corrugated of resistance to thrust, spherical valves open for smaller ; this constant push and pull adjustment for the balance, as long as refrigeration cycle continue
當回氣管道溫度升高，感溫包內的物質膨脹，壓力升高，膨脹波紋箱內壓力也升高，波紋腔膨脹推動推力桿克服彈簧阻力，球型閥開度變大；當回氣管道溫度減低，感溫包內的物質膨脹，壓力降低，膨脹波紋箱內壓力也降低，彈簧阻力推動推力桿壓縮波紋腔，球型閥開度變小；如此不斷的進行推拉調整平衡，只要製冷循環繼續下去。The principle and design scheme are described, the corresponding experimental research is conducted and application foreground of the rotary - switching regenerator is analyzed the result indicates that rotary switching regenerator has the advantages of continual gas supply, low leakage rate, low pressure drop and compact equipment
研究結果表明檔位蓄熱器具有以下特點：可實現對爐窯的連續供氣，保證了爐內火焰的穩定性，從而使爐內工況不易波動；另外系統的漏風率較低，阻力損失也較低，並且設備緊湊、操作安全可靠，易於實現標準化生產。Abstract : ultrasonic welding for ribbon is widely used in developed countries ， electric resistance welding is still used in china. on absorbing foreign advanced technology ， the key assembly of the ultrasonic welding machine i. e. pneumatic working platform was manufatured. the cost of the machine and its spare parts is only 1 / 3 of the imports. the machine has been operated in a factory for four years ， and has been proved stable and reliable. the machine can substitute the imports
文摘:超聲波焊接是發達國家色帶生產企業普遍採用的色帶焊接方法，而國內企業均採用落後的電阻絲焊.為此，在吸收消化國外先進技術的基礎上，自行開發了色帶焊接機的關鍵部件? ?氣動工作臺，實現了超聲波色帶焊接機的國產化，整機及配件價格不到進口產品的1 / 3 .產品經工廠4年多的實際應用，性能穩定、可靠，完全可替代進口分享友人
