style="text-indent:25px">轉(zhuǎn)子流量計(jì)工作原理：當(dāng)測量流體的流量時(shí)，被測流體從錐形管下端流入，流體的流動(dòng)沖擊著轉(zhuǎn)子，并對(duì)它產(chǎn)生一個(gè)作用力，當(dāng)流量足夠大時(shí)，產(chǎn)生的作用力將轉(zhuǎn)子托起。同時(shí)，被測流體流經(jīng)轉(zhuǎn)子與錐形管壁間的環(huán)形斷面，這時(shí)作用在轉(zhuǎn)子上的力有三個(gè):流體對(duì)轉(zhuǎn)子的動(dòng)壓力、轉(zhuǎn)子在流體中的浮力和轉(zhuǎn)子自身的重力。流量計(jì)垂直安裝時(shí)，轉(zhuǎn)子重心與錐管管軸會(huì)相重合，超聲流量計(jì)經(jīng)銷商，作用在轉(zhuǎn)子上的三個(gè)力都沿平行于管軸的方向。當(dāng)這三個(gè)力達(dá)到平衡時(shí)，轉(zhuǎn)子就平穩(wěn)地浮在錐管內(nèi)某一位置上，超聲流量計(jì)經(jīng)銷商。對(duì)于給定的轉(zhuǎn)子流量計(jì)，超聲流量計(jì)經(jīng)銷商，轉(zhuǎn)子大小和形狀己經(jīng)確定，因此它在流體中的浮力和自身重力都是已知是常量，唯有流體對(duì)浮子的動(dòng)壓力是隨來流流速的大小而變化的。因此當(dāng)來流流速變大或變小時(shí)，轉(zhuǎn)子將作向上或向下的移動(dòng)，相應(yīng)位置的流動(dòng)截面積也發(fā)生變化，直到流速變成平衡時(shí)對(duì)應(yīng)的速度，轉(zhuǎn)子就在新的位置上穩(wěn)定。對(duì)于一臺(tái)給定的轉(zhuǎn)子流量計(jì)，轉(zhuǎn)子在錐管中的位置與流體流經(jīng)錐管的流量的大小成一一對(duì)應(yīng)關(guān)系。超聲波流量計(jì)的安裝要避免安裝在管道系統(tǒng)的高點(diǎn)或帶有自由出口的豎直管道上。超聲流量計(jì)經(jīng)銷商</p><div

style="text-indent:25px">差壓式流量計(jì)應(yīng)用范圍特別廣。差壓式流量計(jì)在封閉管道的流量測量中各種對(duì)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(dòng)條件方面：亞音速、音速、脈動(dòng)流等。它在各工業(yè)部門的用量約占流量計(jì)全部用量的1/4~1/3。1、常用標(biāo)準(zhǔn)節(jié)流裝置（孔板）、（噴嘴）、（文丘利管）。2、常用非標(biāo)準(zhǔn)節(jié)流裝置有（雙重孔板）、（圓缺孔板）、（1/4圓噴嘴）和（文丘利噴嘴）。3、孔板常用取壓方法有（角接取壓）、（法蘭取壓），其它方法有（理論取壓）、（徑距取壓）和（管接取壓）。4、標(biāo)準(zhǔn)孔板法蘭取壓法，上下游取壓孔中心距孔板前后端面的間距均為（25.4±0.8）mm，也叫1英寸法蘭取壓。</p><p style="text-indent:25px">流量計(jì)在使用過程中，要延長其使用壽命，需要及時(shí)的對(duì)流量計(jì)進(jìn)行維護(hù)，為了防止流量計(jì)表頭的計(jì)數(shù)器的齒輪卡死或者損壞，需要定期對(duì)齒輪進(jìn)行潤滑，防止計(jì)數(shù)器的使用壽命縮短。流量計(jì)在新建管道中應(yīng)用時(shí)常見的問題。雖然新建管道在投運(yùn)之前都進(jìn)行清潔吹掃工作，但在投運(yùn)過程中難免會(huì)有部分的焊渣殘留物等雜物會(huì)存在其中，這些殘留物會(huì)對(duì)流量計(jì)轉(zhuǎn)子造成破壞（劃傷，卡斷）這樣的話流量計(jì)就會(huì)無法正常使用。為了防止這一情況的發(fā)生，可以使用短管代替流量計(jì)進(jìn)行投運(yùn)時(shí)的試運(yùn)行，確認(rèn)管道內(nèi)無任何雜物后，再采用流量計(jì)進(jìn)行測量，這樣可以避免流量計(jì)轉(zhuǎn)子損壞的現(xiàn)象。差壓式流量計(jì)在封閉管道的流量測量中各種對(duì)象都有應(yīng)用。</p><div

style="text-indent:25px">孔板流量計(jì)工作原理：流體充滿管道，流經(jīng)管道內(nèi)的節(jié)流裝置時(shí)，流束會(huì)出現(xiàn)局部收縮，從而使流速增加，靜壓力低，于是在節(jié)流件前后便產(chǎn)生了壓力降，即壓差，介質(zhì)流動(dòng)的流量越大，在節(jié)流件前后產(chǎn)生的壓差就越大，所以孔板流量計(jì)可以通過測量壓差來衡量流體流量的大小。這種測量方法是以能量守衡定律和流動(dòng)連續(xù)性定律為基準(zhǔn)的。工作特點(diǎn)：①節(jié)流裝置結(jié)構(gòu)簡單、牢固，性能穩(wěn)定可靠，使用期限長，價(jià)格低廉;②應(yīng)用范圍廣，全部單相流皆可測量，部分混相流亦可應(yīng)用;③標(biāo)準(zhǔn)型節(jié)流裝置無須實(shí)流校準(zhǔn)，即可投用;④ 一體型孔板安裝更簡單，無須引壓管，可直接接差壓變送器和壓力變送器。目前單位使用的流量計(jì)大部分都是容積式流量計(jì)。變面積流量計(jì)價(jià)錢</p><p

style="text-indent:25px">渦輪流量計(jì)工作原理：在一定的流量范圍內(nèi)，渦輪的轉(zhuǎn)速與流體的流速成正比。流體流動(dòng)帶動(dòng)渦輪轉(zhuǎn)動(dòng)，渦輪的轉(zhuǎn)速轉(zhuǎn)換成電脈沖，用二次表顯示出數(shù)據(jù)，反應(yīng)流體流速。工作特點(diǎn)：①抗雜質(zhì)能力強(qiáng);②抗電磁干擾和抗振能力強(qiáng);③其結(jié)構(gòu)與原理簡單，便于維修;④幾乎無壓力損失，節(jié)省動(dòng)力消耗。容積式流量計(jì)工作特點(diǎn)：①計(jì)量精度高;②安裝管道條件對(duì)計(jì)量精度沒有影響;③可用于高粘度液體的測量;④范圍度寬;⑤直讀式儀表無需外部能源可直接獲得累計(jì)，總量，清晰明了，操作簡便;⑥結(jié)構(gòu)復(fù)雜，體積龐大⑦不適用于高、低溫場合;⑧大部分儀表只適用于潔凈單相流體;⑨噪聲和振動(dòng)較大。超聲流量計(jì)經(jīng)銷商</p><p
