安裝要求：阻旋式料位計的安裝應(yīng)使葉片所處的位置避開進(jìn)料口的下部和料倉死料區(qū)，為防止使用中物料的砸擊，應(yīng)在檢測葉片的上方安裝防護(hù)板。如采用加長軸垂直安裝，則應(yīng)安裝保護(hù)套筒或使葉片和軟軸所處位置不至受到物料的直接砸擊。多位測量時應(yīng)適當(dāng)拉開距離，避免發(fā)生軟軸的相互纏繞。為避免室外環(huán)境雨水的滲入，側(cè)裝時應(yīng)使出線口垂直向下并旋緊上蓋，阻旋式料位計圖片。垂直安裝時如有條件，阻旋式料位計圖片，阻旋式料位計圖片，可考慮加裝防雨罩。 </p> <p> <br /> 阻旋式料位計采用機(jī)電位控原理，接觸測量料位。阻旋式料位計圖片</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="阻旋式料位計圖片,料位計"

料位計的工藝特點：由于不同的工業(yè)生產(chǎn)過程的特點不同，所以料位計需針對不同的工藝條件來確定。為了能夠更明確地分析物位儀表，料位儀表的工作原理、特點和應(yīng)用環(huán)境，必須對物位測量的工藝要求進(jìn)行明確分析。 </p> <p> 首先我們來分析液位測量的工藝特點: </p> <p> 1.液面是規(guī)則表面。但當(dāng)液體流進(jìn)、流出時容易產(chǎn)生波動或生產(chǎn)過程中出現(xiàn)起泡、沸騰等變化時同樣也會產(chǎn)生波動。 </p> <p> 2.容器內(nèi)發(fā)生有液體各處密度、黏度或溫度等物理量不均勻的現(xiàn)象。 </p> <p> 3.容器內(nèi)發(fā)生有高壓、高溫、液體黏度過大、大量臟污雜質(zhì)、懸浮物等。 </p> <p> 固體物料的物理、化學(xué)性質(zhì)較復(fù)雜，如有顆粒狀的、也有粉末狀的，并且有些介質(zhì)為大小不均勻的顆粒;固體物料的含水量變化、溫度等也是不均勻的變化;料倉振動、料倉形狀不規(guī)則等。阻旋式料位計圖片在冶金、糧食、面粉，建材，水泥、電力、煤炭、環(huán)保除塵等各行各業(yè)的物料輸送與控制過程中有著廣的應(yīng)用。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="阻旋式料位計圖片,料位計" src="https://tyunfile.71360.com/WaterMark/UploadFile/xalunqian/637332787381660156/5297429.png"></div><p> 雷達(dá)料位計的安裝：(1)當(dāng)測量液態(tài)物料時,傳感器的軸線和介質(zhì)表面保持垂直;當(dāng)測量固態(tài)物料時,由于固體介質(zhì)會有一個堆角,傳感器要傾斜一定的角度。(2)盡量避免在發(fā)射角內(nèi)有造成假反射的裝置。特別要避免在距離天線近的1/3錐形發(fā)射區(qū)內(nèi)有障礙裝置(因為障礙裝置越近,虛假反射信號越強(qiáng))。若實在避免不了,建議用一個折射板將過強(qiáng)的虛假反射信號折射走。這樣可以減小假回波的能量密度,使傳感器較容易地將虛假信號濾出。(3)要避開進(jìn)料口,以免產(chǎn)生虛假反射。(4)傳感器不要安裝在拱形罐的中心處(否則傳感器收到的虛假回波會增強(qiáng)),也不能距離罐壁很近安裝,安裝位置在容器半徑的1/2處。(5)要避免安裝在有很強(qiáng)渦流的地方。如:由于攪拌或很強(qiáng)的化學(xué)反應(yīng)等,建議采用導(dǎo)波管或旁通管安裝方式。(6)若傳感器安裝在接管上,天線必須從接管伸出來。喇叭口天線伸出接管至少10mm。棒式天線接管長度100mm或250mm。接管直徑250mm?？梢圆扇〖哟蠼庸苤睆降姆椒?以減少由于接管產(chǎn)生的干擾回波。 </p><p> 料位計在靜電除塵中的應(yīng)用 </p> <p> 除塵器的灰斗是收塵設(shè)備中比較關(guān)鍵的一個部件，它將除塵過程中的廢塵收集起來，以應(yīng)用的廣的布袋式除塵器來說，當(dāng)進(jìn)氣口的含大量灰塵的煙氣在強(qiáng)大的負(fù)壓下碰撞到阻擋灰塵的布袋上時，質(zhì)量較大的部分直接落入灰斗中，而質(zhì)量小的灰塵附著在布袋表面，在反吹風(fēng)或脈沖噴氣閥氣流的外力作用下機(jī)械抖動以達(dá)到清灰的過程，清理的灰塵全都落入灰斗中，長期處于工況中的除塵器一般都是連續(xù)工作，在線分室清灰，這時大量的被清理的灰塵源源不斷地落入灰斗中，灰斗的容積卻是有限的，所以必須在灰斗中灰塵裝滿之前就要有一個反饋信號給PLC系統(tǒng)，以便安排時間清理掉灰斗里的灰塵以便繼續(xù)工作，這時一般灰斗部分會加裝一個可控的卸灰閥方便將灰塵轉(zhuǎn)移出來。以上過程中的反饋信號就要靠料位計來產(chǎn)生了，料位計是安裝在灰斗中的探測灰塵在灰斗中的位置的儀器，有了它就可以知道灰斗中的灰有多少了，以便組織工作。料位計可分為射頻導(dǎo)納式物位控制器、重錘式料位計、阻移式物位計等。通過波紋管散熱器，將雷達(dá)天線傳遞的熱量通過散熱器散發(fā)到空氣中，從而降低雷達(dá)表頭的溫度。</p><div

講講阻旋式料位計和電容式料位計的接線問題。一、阻旋式料位計要看清電壓等級。內(nèi)部有六個端子，兩根電池線，一根接地線，三根信號線（公共線、L線、H線）。二、電容式料位計有四個端子需要接線，兩根電池線，兩根信號線。根據(jù)圖紙，其中一根電池線可和信號線的L線或H線共接一根線的。（上料位接公共線和H線；下料位接公共線和L線）電容式料位計接線要看清電壓等級，發(fā)送罐一般都用24V的。內(nèi)部共有4個端子，接線圖見蓋子內(nèi)側(cè)的說明。端子1為24V電池正，端子2為24V電池負(fù)，端子3端子4是一組無源常開點。根據(jù)圖紙，其中一根電池線可和端子3或端子4共接一根線。如果無法識別同一個罐上的上下料位，只要觀察上面標(biāo)簽貼的型號，一般S1000的罐子，上料位為350MM，下料位為1600MM。液料桶的料位計中浮球式、折角式只要接兩根線就可了，桿式的要接三根線（上料位線、下料位線、公共線）。導(dǎo)波雷達(dá)物位計，采用了可發(fā)出高頻率微波，沿著探桿傳播，由于遇到被測介質(zhì)，介電常數(shù)突變，引起反射。阻旋式料位計圖片</p><p style="text-indent:25px">阻旋式料位計主要用于各種物料料倉極限料位的自動檢測與控制，不同型號的料位器可滿足不同工況的要求。阻旋式料位計圖片</p><p> 雷達(dá)料位計的選型： </p> <p> 天線是雷達(dá)料位計的眼睛,天線的形狀必須適合電磁波的物理特性。天線的外形決定雷達(dá)波的聚焦和靈敏度,就如同麥克風(fēng)的靈敏度一樣。 </p> <p> (1)喇叭口天線適用于絕大多數(shù)場合,聚焦特性特別好。工作壓力可達(dá)64 bar(1 bar=100 kPa)。如果采用相應(yīng)的冷卻措施,被測介質(zhì)的溫度可達(dá)1 000℃。在現(xiàn)場許多存儲罐和反應(yīng)槽選用此類型天線。但不適用于腐蝕性介質(zhì)的測量。(2)棒式天線的安裝法蘭尺寸小,化學(xué)穩(wěn)定性很好,易清洗對冷凝水的粘附不敏感,特別適合于測量腐蝕性介質(zhì),工作壓力可達(dá)16 bar,被測介質(zhì)的溫度可達(dá)200℃。其發(fā)射角較大,信噪比小,常用測量條件較好的槽罐及用于腐蝕性介質(zhì)的測量。(3)法蘭下置型天線適用于高溫介質(zhì)、腐蝕性介質(zhì)或不能在頂部安裝的測量環(huán)境。(4)安裝套管的天線:套管對雷達(dá)波具有聚焦作用。當(dāng)介質(zhì)介電常數(shù)較低(1.6~3)或液面產(chǎn)生持續(xù)渦流或容器內(nèi)裝置造成假反射時,可選該類表。天線裝在導(dǎo)波管中或旁通管中,套管會對運(yùn)行時間產(chǎn)生影響,所以要將套管的內(nèi)徑輸入電子部件,以對運(yùn)行時間的變化進(jìn)行補(bǔ)償。另外要求被測介質(zhì)的流動性比較好,不易形成掛料。(5)外殼的材質(zhì):鋁殼儀表不耐堿的腐蝕,在這種場合盡量選用塑料的。(6)槽、罐比較高時宜選用拋物面天線。阻旋式料位計圖片</p></p><br
