pitot static tube
解釋
動靜壓管-
The pitot-static tube can be used only in free air.
皮託管僅能用在自由流中。 -
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。 -
