氧氣噴管 的英文怎麼說
中文拼音 [yǎngqìpēnguǎn]
氧氣噴管
英文
oxygen nozzle-
Owing to the high proportion of unburnt oxygen in this efflux, afterburners are often provided in the jet-pipe.
由於這種噴氣流中含有大量未燃燒的氧氣，在噴管中往往安裝加力燃燒室。Pressurized with nitrogen or carbon dioxide gas, the powders are expelled through a discahrge hose
施壓力于氮或一氧化碳氣體，乾粉將從管中噴射而出。Exhaust gas oxygen sensor ( ego ) which is installed in the exhaust pipe of the engine is a significant component in the electronic fuel injection. it has the ability to probe the concentration of oxygen in the exhaust pipe, and can transfer concentration signal to voltage signal which is passed to electronic control unit ( ecu ). in this way the air - fuel ratio can be controlled to the strait range of stoichiometrical point and the three - way catalytic converter consequently can work better
車用氧傳感器是電噴系統的關鍵部件，安裝在發動機的排氣管上，能夠探測排氣管中的氧氣的濃度，然後將濃度信號轉變成電壓信號並傳送給電控單元ecu ，從而把空燃比控制在理論空燃比附近，配合三元催化反應器進行后處理凈化。In the aspect of thermal spraying processes the main techniques applied to water wall tubes include flame spray, arc spraying, plasma spray and high velocity oxy - fuel spray ( hvof ). flame spray possesses the characteristics of simple equipment, easy of use and low operating cost, but the coating adhesive strength is low, and porosity and oxidation is high
在噴塗工藝方面，制備管道塗層的方法主要有火焰噴塗、電弧噴塗、等離子噴塗、超音速火焰噴塗等。火焰噴塗具有設備簡單、使用方便、操作成本低的特點，但它的塗層結合強度低，氣孔率及氧化物含量高。When liquid propellants are used the fuel and oxidize are fed under pressure to one or more combustion chambers and expanded to atmosphere through convergent-divergent nozzles.
當使用液體推進劑時，在壓力作用下，燃料和氧化劑輸送到一個或幾個燃燒室中，並通過收斂-打散噴管，排到大氣中。It is shown that when the exit area of secondary nozzle and the fuel / oxidizer ratio is fixed, the increase of mass flow rate of secondary flow lead to the decrease of velocity of mixed flow, and increase of total mass flow rate. the synthetical result of these two phenomenon cause the increase of thrust of rocket ejector, but the increasing magnitude is relatively small, indicating that these is no necessary to claim large bypass ratio in rocket ejector design. in the comparison between two configurations, the typical one has better performance, indicating the importance of pressure ratio
結果表明：在固定二次噴管出口面積和氧燃比的條件下，二次流（引射空氣流）流量的增加引起混合氣體出口速度的下降和總流量的增加，二者綜合作用使發動機推力增加，但增幅不大，表明在設計發動機結構和工作參數時，不必過分追求大的引射系數；兩種結構的性能對比分析表明了增壓比對引射火箭性能的提高具有重要意義；對引射火箭的熱力循環分析同樣表明，增壓比對于提高發動機性能非常關鍵。分享友人
