pitot pressure 中文意思是什麼
pitot pressure
解釋
動靜壓-
At first, in the process of experiments, it were measured that dry plate pressures drop and point pressures in the flow fields around the single fixed - valve and double fixed - valves under different velocities by using of pitot tube. after that point pressure was transformed to point velocity, two dimensions flow plane of flow fields around fixed - valve were plotted to observe the difference between of the fixed - valve tray with fold edges and the common rectangular fixed - valve tray on the distributions of flow fields and pressures, to provide comparisons and refer - rence for cfd simulation
在實驗中，利用測速管等儀器對在不同速度下的單閥和雙閥固定閥周圍的流場進行了點壓力測量，然後把點壓力轉化為點速度后繪出固定閥周圍流場的二維流線圖，同時測定了塔板的干板壓降，來考察新型固定閥帶折邊后對流場分佈和壓降的影響，為隨后的數值模擬提供對比和依據。 -
Measurement precision contribute to improving the security class and economic of boiler running and automatic level of whole plant. the smart measurement instrument of the boiler ’ s air flow designed in the thesis and the instrument can make the degree of accuracy get to. firstly, the thesis build the “ velocity - area ” method which is on basis of “ log - tchebycheff ” on the analyzing of basic measure method of boiler ’ s air flow. secondly, model86 averaging pitot tube was selected the right model of flow transducer which can pickoff the differential pressure and static pressure. modelc264 which made in setra system corp. u. s. a was selected as ultra low differential pressure transmitter. a good flow of boiler ’ s air was calculated by offsetting pressure and temperature. finally, numeroscope was designed with z80cpu and other chips
精確的監測有助於提高鍋爐燃燒的安全型、經濟性，也有助於提高電廠的整體自動化水平。本文設計的智能化鍋爐風量測量裝置能夠實現對鍋爐送風的精確測量，精度可達。本文首先研究鍋爐送風矩形大管道測量理論，提出在流來流量測量測點布置基於「對數-切比雪夫」法的速度-面積法。 -
