BURKERT流量計詳細介紹
BURKERT流量計就是在一種計量產(chǎn)品,它符合一般的價值規(guī)律,精度越高,價格越高,重量越大,價格越高,功能越多,價格越高,進口的產(chǎn)品比國產(chǎn)的貴。
既然說到選型原則,那么必然要考慮功能、價格各方面的因素。比如說用戶只要測量一個四寸管道的水的瞬時流量,那么大部分的流量計都可以滿足測量要求,格的數(shù)百元,zui高價格的可能數(shù)十萬,就只能看用戶怎么選擇了。
寶德5281型電磁閥伺服輔助電磁閥帶伺服膜,適用于控制液體或氣體介質(zhì)。通用型zui高壓力16bar,NBR,EPDM和FPM伺服膜,防水錘,低噪音,回路功能為常閉或常開,黃銅閥體,螺紋或法蘭連接。
寶德6213型電磁閥兩位兩通常閉電磁閥帶耦合膜片系統(tǒng)。零壓啟動,可廣泛用于液體介質(zhì),如中性液體,水、液壓油、不含添加劑的油;高溶溶液、含添加劑的熱油;無油和無脂液體。分為黃銅和不銹鋼閥體。DN10-40mm。
2000型外部先導(dǎo)控制角座閥有但作用或雙作用活塞執(zhí)行機構(gòu)驅(qū)動。執(zhí)行機構(gòu)有兩種材質(zhì),適用于不同的環(huán)境溫度,炮艇或不銹鋼兩通閥體,流量大。
BURKERT流量計是根據(jù)安裝于管道中流量檢測件產(chǎn)生的差壓,已知的流體條件和檢測件與管道的幾何尺寸來計算流量的儀表。
BURKERT流量計由一次裝置(檢測件)和二次裝置(差壓轉(zhuǎn)換和流量顯示儀表)組成。通常以檢測件形式對差壓式流量計分類,如孔板流量計、文丘里流量計、均速管流量計等。
二次裝置為各種機械、電子、機電一體式差壓計,差壓變送器及流量顯示儀表。它已發(fā)展為三化(系列化、通用化及標(biāo)準(zhǔn)化)程度很高的、種類規(guī)格龐雜的一大類儀表,它既可測量流量參數(shù),也可測量其它參數(shù)(如壓力、物位、密度等)。
BURKERT流量計的檢測件按其作用原理可分為:節(jié)流裝置、水力阻力式、離心式、動壓頭式、動壓頭增益式及射流式幾大類。
檢測件又可按其標(biāo)準(zhǔn)化程度分為二大類:標(biāo)準(zhǔn)的和非標(biāo)準(zhǔn)的。
所謂標(biāo)準(zhǔn)檢測件是只要按照標(biāo)準(zhǔn)文件設(shè)計、制造、安裝和使用,無須經(jīng)實流標(biāo)定即可確定其流量值和估算測量誤差。非標(biāo)準(zhǔn)檢測件是成熟程度較差的,尚未列入標(biāo)準(zhǔn)中的檢測件。
BURKERT流量計是一類應(yīng)用zui廣泛的流量計,在各類流量儀表中其使用量占居*。近年來,由于各種新型流量計的問世,它的使用量百分數(shù)逐漸下降,但目前仍是zui重要的一類流量計。
BURKERT流量計流體體積流量公式為:v=aA√2/j(p-q)
一種新型產(chǎn)品:引進美國航天航空局而開發(fā)的平衡流量計,這種流量計的測量精度是傳統(tǒng)節(jié)流裝置的5-10倍,*壓力損失1/3。壓力恢復(fù)快2倍,zui小直管段可以小至1.5D,安裝和使用方便,大大減少流體運行的能力消耗。
BURKERT流量計應(yīng)用范圍特別廣泛,在封閉管道的流量測量中各種對象都有應(yīng)用,如流體方面:單相、混相、潔凈、臟污、粘性流等;工作狀態(tài)方面:常壓、高壓、真空、常溫、高溫、低溫等;管徑方面:從幾mm到幾m;流動條件方面:亞音速、音速、脈動流等。它在各工業(yè)部門的用量約占流量計全部用量的1/4~1/3。
BURKERT流量計,又稱轉(zhuǎn)子流量計,是變面積式流量計的一種,在一根由下向上擴大的垂直錐管中,圓形橫截面的浮子的重力是由液體動力承受的,從而使浮子可以在錐管內(nèi)自由地上升和下降。
BURKERT流量計是僅次于差壓式流量計應(yīng)用范圍zui寬廣的一類流量計,特別在小、微流量方面有舉足輕重的作用。
