required air quantity
解釋
所需空氣量-
Whole scheme of frame design of test - bed is proposed as : the host fanner supply the firebox the once and twice air required by diesel oil ' s burning and the cooling air ; the export parameter of the test - bed is varied by the adjust of the flux of air and diesel oil. and the air flux is varied by adjusting the rev of the fanner adjusted by transducer and the corner of the fan inlet adjusted by step motor. the quantity of oil is varied by adjusting the oil valve adjusted by step motor ; the measurement of the air flux in the test - bed adopts the method of fanner dynamics performance test in the nation criterion
確立了實驗臺結構設計方案：主風機為燃燒器提供燃燒所需的一次、二次進風量及冷卻風量；利用變頻器調節主風機轉速、用步進電機調節風門開度來調節風量，用步進電機調節回油閥開度來調節供油量，從而實現對模擬實驗臺出口煙氣熱流量的調節；實驗臺的流量測量採用風機動力性能測試標準中測流量方法等。 -
Whole scheme of frame design of testing flat is proposed as : the host fanner supply the air required by flamer ’ s burning and cooling, the export parameter of the flat varies by different rotate speed of the fanner 、 angle of the fan inlet and the quantity of oil, the measurement of flow in the testing flat adopts the method of fanner dynamics performance test in the nation criterion
確立了實驗臺結構設計方案：主風機為燃燒器提供燃燒所需的一次、二次進風量及冷卻風量；模擬實驗臺出口煙氣熱流量是通過調節風機的轉速、風門開度及燃油量來改變；實驗臺的流量測量採用風機動力性能測試標準中流量方法等。 -
With the fast increasing of air traffic, the safety problems are outstanding. so a large quantity of atc systems with high functionality and reliability are imminently required
隨著我國航空運輸業的飛速發展，航路流量不斷增大，空中交通安全問題已十分突出，實現空管系統的自動化是必然要求，因此這就需要增加大量功能完備、性能先進、可靠性高的空中交通管制系統。
