電磁流量計內(nèi)襯材料正確選用方法： </p> <p> 應(yīng)根據(jù)被測介質(zhì)的腐蝕性，磨損性和溫度來選擇內(nèi)襯材料： </p> <p> 一、天然橡膠（軟橡膠）：1、較好的彈性，耐磨性和扯斷力；2、耐一般的弱酸、弱堿的腐蝕；3、測水、污水。 </p> <p> 二、耐酸橡膠（硬橡膠）：可耐常溫下的鹽酸、醋酸、草酸、氨水、磷酸及50%的硫酸、氫氧化鈉、氫氧化鉀的腐蝕，但不耐強氧化劑的腐蝕；可測一般的酸、堿、鹽溶液。 </p> <p> 三、氯丁橡膠（Neoprene）：1、極好的彈性，高度的扯斷力，耐磨性能好；2、耐一般低濃度的酸堿、鹽溶液的腐蝕，但不耐氧化性介質(zhì)的腐蝕，且溫度要求<80℃；可測水、污水、泥漿和礦漿。 </p> <p> 四、聚胺脂橡膠（Polyurethane）：1、極好的耐磨性能；2、耐酸、堿性能差，溫度要求<40℃；測中性強磨損的煤漿、泥漿和礦漿。 </p> <p> 五、聚四氟乙烯（PTFE）：1、耐沸騰的鹽酸、硫酸、硝酸、王水、濃堿和各種有機溶劑；2，河北衛(wèi)生型渦旋流量計廠家、耐磨性能好，粘接性能差，溫度要求-80～+180℃；測濃度、濃堿強腐蝕性溶液及衛(wèi)生類介質(zhì)，河北衛(wèi)生型渦旋流量計廠家。流量計又分為有差壓式流量計、容積流量計，河北衛(wèi)生型渦旋流量計廠家、電磁流量計、超聲波流量計、渦輪流量計和渦街流量計等等。河北衛(wèi)生型渦旋流量計廠家</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河北衛(wèi)生型渦旋流量計廠家,流量計"

差壓式孔板流量計是一款流量測量儀表，主要應(yīng)用于液體、氣體流量測量，像蒸汽流量測量就是一個典型的測量工況，蒸汽在流量測量的過程中，由于自身溫度較高，測量難度大一般的流量計都無法勝任，而差壓式孔板流量計就可以有效的解決。差壓式孔板流量計的應(yīng)用領(lǐng)域非常廣，測量精度可達±0.5%，溫度可達700度，并且量程比為10：1，主要在氣體、蒸汽、液體的流量測量領(lǐng)域應(yīng)用較多，差壓式孔板流量計還有一個優(yōu)勢就是安裝方便，并且也不需要維護。甘肅一體分體式電磁流量計測量蒸汽只能用專門設(shè)計的金屬管浮子流量計或在標(biāo)準(zhǔn)型儀表上加裝附加構(gòu)件。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="河北衛(wèi)生型渦旋流量計廠家,流量計"

低維護量-市場上大多數(shù)的渦街流量計是采用取壓孔或插入式檢測元件感應(yīng)漩渦，一旦介質(zhì)中雜質(zhì)嵌入取壓孔或感應(yīng)元件與表體間的縫隙，則造成信號變?nèi)趸虿环€(wěn)定。良好的設(shè)計應(yīng)該是沒有容易堵塞的部分，從而降低維護量。 </p> <p> 2. 感應(yīng)元件在線更換-某些廠家的感應(yīng)元件與渦街發(fā)生體合二為一，看似簡單的設(shè)計卻給實際使用帶來不便。因為一旦感應(yīng)部分失效，則需要將管道內(nèi)介質(zhì)排空泄壓后更換部件，影響生產(chǎn)。完善的設(shè)計應(yīng)該是將二者分開，這樣就可以單獨更換感應(yīng)部分，而無需將介質(zhì)排空。 </p> <p> 3. 渦街流量計容易受到振動的干擾，設(shè)計精良的渦街流量計可以通過硬件和數(shù)字信號處理將干擾排除，從而得到穩(wěn)定的信號。 </p> <p> 4. 渦街流量計安裝的一麻煩是前后需要很長的直管段，有些廠家可以提供在流量計內(nèi)部縮徑的設(shè)計，降低了用戶專門維渦街流量計配備直管段的需求。 </p><p> 一體型電磁流量計是根據(jù)法拉第電磁感應(yīng)定律制定，用來測量導(dǎo)電流體的體積流量。由于獨特的特點已廣地應(yīng)用于工業(yè)上各種導(dǎo)電液體的測量。主要用于化工、造紙、食品、紡織、冶金、環(huán)保、給排水等行業(yè)，與計算機配套可實現(xiàn)系統(tǒng)控制。1．電磁流量計沒有可動部件，也沒有阻流件，不會引起壓力損失，同時也不會引起磨損，阻塞等問題。2．電磁流量計是一體積流量測量儀表，在測量過程中不受被測介質(zhì)的溫度、粘度、密度以及導(dǎo)電率（在一定范圍內(nèi)）的影響。3．電磁流量計的量程范圍寬，可達1：100。此外，電磁流量計只與被測介質(zhì)的平均流速成正比，而與軸對稱的流動狀態(tài)（層流或紊流）無關(guān)。4．電磁流量計無機械慣性，反應(yīng)靈敏，可以測量瞬時脈動流量，而且線性好，因此可以將測量信號直接用轉(zhuǎn)換器線性的轉(zhuǎn)換成標(biāo)準(zhǔn)信號輸出。LD-T型可就地指示，LD型可遠距離傳送。應(yīng)用在石化行業(yè)的特殊環(huán)境中，需要堅固耐用的設(shè)計以及防爆認(rèn)證;用戶對直管設(shè)計的科氏流量計的需求等。</p><div

超聲波流量計也是比較常見的流量計，它的安裝在所有流量計的安裝中是zui簡單便捷的，只要選擇一個合適的測量點，把測量點處的管道參數(shù)輸入到流量計中，然后把探頭固定在管道上即可。 </p> <p> 超聲波流量計的安裝主要遵循以下3點：1.選擇充滿流體的材質(zhì)均勻質(zhì)密、易于超聲波傳輸?shù)墓芏?，如垂直管段或水平管段?.安裝距離應(yīng)選擇上游大于10倍直管徑、下游大于5倍直管徑以內(nèi)無任何閥門、彎頭、變徑等均勻的直管段，安裝點應(yīng)充分遠離閥門、泵、高壓電和變頻器等干擾源。3. 避免安裝在管道系統(tǒng)的比較高點或帶有自由出口的豎直管道上。4. 對于開口或半滿管的管道，流量計應(yīng)安裝在U型管段處。河北衛(wèi)生型渦旋流量計廠家</p></p><br /><p>文章來源地址: http://www.cdcfah.com/cp/3069871.html</p></div></div></div></div></div><div id="2syouqw"
