Thermocouple and thermal resistance in power station suit to measure temperature of electric generator groups and auxiliary machine correspond to 300000 and 600000 kilowatt, which can substitute one from import with many advantages as shock - proof, pressure - resistant, long in service, and convenience in maintain etc. the protective tube is processed in a special construction by deep - blind hole technology whose end not be welded to enhance the strength and prolong service life. thermocouple or thermal resistance
本公司生產的電站專用熱電偶阻,適用於我國30萬60萬千瓦等發電機組及輔機的測溫需要,產品安全可替代進口,具有防震耐壓使用壽命長,維修方便,保護管是採用深盲孔技術加工而成,端部不用焊接,提高了保護管的強度和使用壽命,鎧裝熱電偶熱電阻採用彈簧壓著式結構,在運行中保護管與鎧裝熱電偶熱電阻測量端始終保持著良好的接觸,抗震動,減少熱響應時間,鎧裝熱電偶測量端採用絕緣形式,能防止電磁干憂。The results of fe simulation shows that the mental package made abroad has lower thermal stress and higher reliability during working and manufacturing process than that made in china. it is mainly because that the two packaging structures were manufactured in different forming processes : one was punched and the other was brazed
有限元計算的結果表明,採用沖壓一次成型的國外封裝外殼比採用異材壓焊的國產封裝外殼的工作熱應力和製造殘余熱應力要小很多,具有更高的可靠性。( 3 ) the most principal factors that influence the supersonic atomization process include the flow ratio of the gas - liquid metal ( gmr ) value, the flow of atomizing of gas and the range of the inverse vortex taper. the more of the value of three factors, the more advantage they are for the atomization and the more fine the powders are. ( 4 ) the produced powders are the best in efficient atomization efficiency, particle diameter, particle shape and dispersion when the solder alloy is zhl63a, atomizing medium is n2, the protrusion h = 6. 0mm, atomizing gas pressure p = 100mpa, over - heat temperature t = 167 ( t = 350 )
研究結果表明: ( 1 )超音速霧化器的氣體流場在導液管下端形成一個倒渦流錐,在二維空間上呈軸對稱的雙峰分佈,負壓形成於這個倒渦流錐內; ( 2 )修正後的霧化氣體速度公式可以滿足超音速霧化的要求; ( 3 )影響超音速霧化工藝最根本的因素有氣液質量流率比( gmr )的大小、霧化氣體流量和倒渦流錐范圍,三個因素的值越大,對形成細粉越有利; ( 4 )在焊錫合金為zhl63a ,霧化介質微n _ 2 ,導液管突出高度取h = 6 . 0mm ,霧化氣體壓力取p = 1 . 0mpa ,合金過熱度取t = 167 ( t = 350 )時,所制得的粉末在有效霧化率、顆粒球形度、粒度及其離散度三個方面綜合性能最好。Then the paper also study the atomizer structure ( the protrusion of the delivery tube value h ), atomizing gas pressure p, over - heat temperature of alloy a t, the component of solder alloy and atomizing medium and so on
進一步對霧化器結構(導液管突出高度h ) 、霧化氣體壓力p 、合金過熱度t 、焊錫合金成份和霧化介質進行了研究。Abstract : the structure, composition analysis and mechanical test of q235 hot - rolled strip showed that main season of fracture during forming and welding is high nitrogen, oxygen and inclusion content
文摘: q235鋼熱軋卷板在沖壓和焊接成形時出現開裂,對其進行化學分析、宏觀和微觀組織觀察及力學性能測試,結果表明:氮、氧及夾雜物的含量高是該鋼沖壓性和可焊性差的主要原因。The studies of predecessors have proved that multi - tube structure has low pressure loss. moreover, the polypropylene filter medium which can be stuck by hot pressure makes it possible to adopt the multi - tube structure
前人的研究已表明管式結構阻力較小,由於聚丙烯材料可熱壓燙焊的特性能製成濾管才得以採用該種結構。分享友人
