steam ejector 中文意思是什麼
steam ejector
解釋
蒸汽噴射泵-
Under special conditions such as low partial load / deep vacuum, unexpected high air leakage resulting in a major temperature difference ( above 10 c ) between the steam exhaust turbine temperature and all air - take off temperature measurement, the suction capacity can be improved by using 2 main ejector simultaneously
在特殊條件如局部低載荷/極端真空，不正常的熱交換，意想不到的高空氣泄漏導致的在蒸汽排氣溫度和抽空溫度測量上產生的嚴重溫差（ 10 c以上） ，用兩臺主抽汽器同時工作可以提高抽氣量。 -
The experiment took water as the medium and experiments on two jet modes were carried out under the falling film vacuum evaporating. the experimental results indicated that the two ejectors in series compensation method could adjust the variational work situation due to the decrease of primary steam or secondary steam and insure the normal production. at the same time, the ejector ' s best work situation founded in the experiment would provide reference for ejector ' s design and usage
本實驗建立了一套降膜真空蒸發裝置，以水為介質，對變工況下單級和串聯噴射熱泵蒸發進行了實驗，結果表明兩級串聯補償噴射裝置能對由引射蒸汽和工組蒸汽壓力降低所造成的混合蒸汽壓力降低進行調節，達到了變工況下正常生產的目的。 -
Before steam admission, valve on vacuum hogging extraction line （ the valve is befor hogging pipe of the two stage steam jet ejector ） should be closed ( see also two stages steam jet ejector installation and operation instruction )
在蒸汽進入之前，抽真空啟動管道上的閥門（啟動抽汽器前的閥門）應該關閉（請參見相應的兩級射汽抽氣器安裝使用說明書） 。 -
Now, the device has been manufactured. many testing can be studied by this device, such as spraying falling - film 、 falling - film evaporation and performance of steam ejector
參與了實驗裝置的加工製造，該裝置現已建成，利用該實驗臺可以進行噴淋降膜、降膜蒸發傳熱和蒸汽噴射器等多種項目的試驗研究。 -
In the present work, the causing of high noise of multi - effect falling film evaporator was introduced in detail. based on the result of modern test technology, the relationship of noise and work presser was received. ground on the method of superposition, the noise of raw material pump was separated from the mixed noise and gets the true noise of steam - jet - ejector
本文對三效降膜蒸發器設備工作時，噪聲產生的機理進行了理論分析與研究，利用現代聲學測試技術手段進行測試與分析，得出三效降膜蒸發器設備的整體噪聲隨熱壓泵工作壓力增大而增大的關系，利用噪聲疊加原理，將三效降膜蒸發器設備的物料泵噪聲作為背景噪聲，計算得出三效降膜蒸發器設備的熱壓泵真實噪聲，因而得出熱壓泵噪聲亦隨其工作壓力增大而增大的關系。 -
Used the theory of air - dynamic and the jet - ejector principle the characteristic of jet - steam, proving the noise signal have the character of chaos by using the fractal theory. noise sound pressure on the normal condition was checked by theory formula and contrasted with the experimental data. the difference was analyzed in detail
結合空氣動力學噴射氣流噪聲理論公式，驗算了三效降膜蒸發器正常生產時熱壓泵中拉伐爾管噴口處的噪聲聲壓級，與實測值進行對比，並詳細分析了兩者產生較大差異的原因。
