class="title">詳細(xì)說明</p><div id="ixubcjb" class="box"><p><p style="text-indent:25px">根據(jù)一元流動(dòng)的連續(xù)方程，當(dāng)流通截面恒定時(shí)，截面上的平均流速與體積流量成正比，于是各種與流速有關(guān)的物理現(xiàn)象便可以用來建立流量計(jì)。例如：超聲波流量計(jì)、渦輪流量計(jì)、動(dòng)壓測量管、漩渦流量計(jì)和節(jié)流式流量計(jì)等均屬于此類。目前流量儀表中以這類儀表**多，它們有較寬的使用條件，雅安流量儀表廠家，有用于高溫高壓流體的，也有精度較高的，雅安流量儀表廠家，有的能量損失很小，有的可適應(yīng)臟污介質(zhì)等等，雅安流量儀表廠家。使流體流動(dòng)得到某種加速度的力學(xué)效應(yīng)與質(zhì)量的關(guān)系，是這種方法的物理基礎(chǔ)，按這種原理制成的流量計(jì)有質(zhì)量流量計(jì)和回轉(zhuǎn)管式流量計(jì)等。雅安流量儀表廠家</p><div

style="text-indent:25px">化工生產(chǎn)中所處理的物料大部分是流體，它們通過動(dòng)力設(shè)備，如鼓風(fēng)機(jī)、泵等，在管道中輸送。工業(yè)上用于測量流體流量的儀表叫做流量計(jì)或流量儀表、流量測量的重要目的有如下兩個(gè)方面； 1．流量不但是控制化工生產(chǎn)及監(jiān)督設(shè)備工況的重要參數(shù)，也是物料流動(dòng)工況特征參數(shù)之一，同時(shí)對(duì)確保正常生產(chǎn)，亦有很大意義。 2．流量又是車間、工廠實(shí)行企業(yè)經(jīng)濟(jì)核算的基礎(chǔ)依據(jù)，生產(chǎn)廠要準(zhǔn)確地測出水、蒸汽、燃料氣、原料或動(dòng)力消耗的情況，以加強(qiáng)企業(yè)管理。因此，操作人員對(duì)流量的測量，必須給予足夠的重視。由于流量測量的目的不同，對(duì)流量測量的要求也不同。前一種則要求儀表穩(wěn)定、靈敏，后一種則要求儀表準(zhǔn)確、可靠。雅安流量儀表廠家</p><div

style="text-indent:25px">流量測量的方法很多，儀表的種類也很多，結(jié)合流量的定義，常用的流量測量方法可歸納為容積法，流速法和質(zhì)量流量法等。如果流體是以固定體積從流量計(jì)中逐次排放流出，則對(duì)排放的次數(shù)計(jì)數(shù)，就可以求得通過儀器的流體總量。若測量排放的頻率，即可顯示流量。這種方法叫做容積法。如刮板流量計(jì)。橢圓齒輪流量計(jì)和標(biāo)準(zhǔn)體積管等，都是按此原理工作的。這類儀表所顯示的是體積流量的總量。容積法的特點(diǎn)是流動(dòng)狀態(tài)對(duì)測量的影響較小，精確度較高，這類流量計(jì)一般不宜用于測量高溫高壓流體和臟污介質(zhì)的流量，測量流量的上限也不大。</p><p style="text-indent:25px">量儀表(流量計(jì))的選型對(duì)儀表能否成功使用往往起著很重要的作用，由于被測對(duì)象的復(fù)雜狀況以及儀表品種繁多、性能指標(biāo)各使得儀表的選型感到困難。沒有一種十全十美的流量計(jì)，各類儀表都有各自的特點(diǎn)，選型的目的就是在眾多的品種中揚(yáng)長避短選擇自己**合適的流量計(jì)儀表。流量計(jì)儀表選型的步驟如下： 1、依據(jù)流體種類及五個(gè)方面考慮因素初選可用儀表類型(要有幾種類型以便進(jìn)行選擇)； 2、對(duì)初選類型進(jìn)行資料及價(jià)格信息的收集，為深入的分析比較準(zhǔn)備條件； 3、采用淘汰法逐步集中到1～2種類型，對(duì)五個(gè)方面因素要反復(fù)比較分析**終確定預(yù)選目標(biāo)。</p><div
