style="text-indent:25px">1．探頭結(jié)疤和頻繁故障的解決方法個(gè)辦法是將探頭安裝位置提高，但是有時(shí)候安裝條件限制，不能提高的情況下，就應(yīng)采用將料位測(cè)量值與該槽的泵聯(lián)鎖的辦法，解決這一難題：將比較高料位設(shè)定值減小0.5m左右，當(dāng)料位達(dá)到該比較高值時(shí)，即可停進(jìn)料泵或開啟出料泵。2．雷達(dá)料位計(jì)被淹相應(yīng)的改進(jìn)辦法解決這種問(wèn)題的辦法是將雷達(dá)料位計(jì)改為導(dǎo)波管式測(cè)量。仍在原開孔處安裝導(dǎo)波管式雷達(dá)料位計(jì)，導(dǎo)波管高于排汽管0.2m左右，這樣一來(lái)，即使出現(xiàn)料漿從排汽管溢出的惡劣工況，也不會(huì)使料位計(jì)天線被料漿淹沒(méi)，而且避免了攪拌器渦流的干擾及大量蒸汽從探頭處冒出，減少了對(duì)探頭的損害，同時(shí)由于導(dǎo)波管聚焦效果好，接收的雷達(dá)波信號(hào)更強(qiáng)，取得了很好的測(cè)量效果。使用導(dǎo)波管測(cè)量方式，可以改善表計(jì)測(cè)量條件，提高儀表測(cè)量性能,具有很高的推廣應(yīng)用價(jià)值。3．關(guān)于泡沫對(duì)測(cè)量的影響干泡沫和濕泡沫能將雷達(dá)波反射回來(lái)，對(duì)測(cè)量無(wú)影響；中性泡沫則會(huì)吸收和擴(kuò)散雷達(dá)波，因而嚴(yán)重影響回波的反射甚至沒(méi)有回波。當(dāng)介質(zhì)表面為稠而厚的泡沫時(shí)，測(cè)量誤差較大或無(wú)法測(cè)量，在這種工況下，雷達(dá)料位計(jì)不具有優(yōu)勢(shì)，這是其應(yīng)用的局限性。南通雙腔雷達(dá)料位計(jì)銷售廠家雷達(dá)料位計(jì)在標(biāo)定中采納了多種抗攪擾的措施后，其測(cè)量準(zhǔn)確度和運(yùn)轉(zhuǎn)牢靠性大幅進(jìn)步。</p><div

當(dāng)測(cè)量液態(tài)物料時(shí)，傳感器的軸線和介質(zhì)表面保持垂直；當(dāng)測(cè)量固態(tài)物料時(shí)，由于固體介質(zhì)會(huì)有一個(gè)堆角，傳感器要傾斜一定的角度。 </p> <p> (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?yàn)檎系K裝置越近，虛假反射信號(hào)越強(qiáng)）。若實(shí)在避免不了，建議用一個(gè)折射板將過(guò)強(qiáng)的虛假反射信號(hào)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(hào)濾出。 </p> <p> (3) 要避開進(jìn)料口，以免產(chǎn)生虛假反射。 </p> <p> (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(huì)增強(qiáng)），也不能距離罐壁很近安裝，比較好安裝位置在容器半徑的1/2處。 </p> <p> (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)波管或旁通管測(cè)量。 </p> <p> (6) 若傳感器安裝在接管上，天線必須從接管伸出來(lái)。喇叭口天線伸出接管至少10mm。棒式天線接管長(zhǎng)度比較大100或250mm。接管直徑小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> 高頻雷達(dá)料位計(jì)測(cè)量?jī)?yōu)勢(shì) </p> <p> 高頻雷達(dá)料位計(jì)是先進(jìn)的雷達(dá)式物位測(cè)量?jī)x表，測(cè)量最大距離可達(dá)70米。天線被進(jìn)一步優(yōu)化處理，適用于固體料、過(guò)程容器或強(qiáng)粉塵易結(jié)晶、結(jié)露場(chǎng)合。具有低維護(hù)，高性能、高精度、高可靠性，使用壽命長(zhǎng)等優(yōu)點(diǎn)?？梢赃m應(yīng)高溫、高壓、蒸汽等惡劣的生產(chǎn)環(huán)境。高頻雷達(dá)料位計(jì)有哪些優(yōu)勢(shì)？ </p> <p> 1.高頻雷達(dá)料位計(jì)具有能量高，波束角小，天線尺寸小，精度高等優(yōu)勢(shì)特點(diǎn)。 </p> <p> 2.高頻雷達(dá)料位計(jì)發(fā)射的電磁波波長(zhǎng)為11mm，是測(cè)量散裝料物位比較好選擇的原因。 </p> <p> 3.在一些直徑小而高度并不是很高的小型罐的應(yīng)用中，26GHz高頻雷達(dá)料位計(jì)頻率高、天線短、方向性好，更適用于小罐測(cè)量。 </p> <p> 4.由于現(xiàn)場(chǎng)環(huán)境惡劣，隨著時(shí)間推移，雷達(dá)天線會(huì)堆積污物、水汽等，26GHz高頻雷達(dá)料位計(jì)天線小，附加天線罩可改善因污物、水汽的影響 </p> <p> 4．因?yàn)?6GHz高頻雷達(dá)料位計(jì)方向性好，所以在很多惡劣工況下，可通過(guò)簡(jiǎn)單隔離，將雷達(dá)料位計(jì)裝在容器外進(jìn)行測(cè)量雷達(dá)料位計(jì)幾乎免維護(hù)、無(wú)破損、掛料等現(xiàn)象，無(wú)配件更換問(wèn)題、壽命長(zhǎng)，且安裝簡(jiǎn)單、標(biāo)定簡(jiǎn)單。</p><div

</p> <p> <br /> </p> <p> 雷達(dá)料位計(jì)的基本原理 </p> <p> 雷達(dá)式料位計(jì)組成：它主要由發(fā)射和接收裝置、信號(hào)處理器、天線、操作面板、顯示、故障報(bào)警等幾部分組成。 </p> <p> 發(fā)射－反射－接收是雷達(dá)式料位計(jì)工作的基本原理。雷達(dá)傳感器的天線以波束的形式發(fā)射比較小5.8GHz的雷達(dá)信號(hào)。反射回來(lái)的信號(hào)仍由天線接收，雷達(dá)脈沖信號(hào)從發(fā)射到接收的運(yùn)行時(shí)間與傳感器到介質(zhì)表面的距離以及物位成比例。即：h= H–vt/2 式中 h為料位；H為槽高；v為雷達(dá)波速度；t為雷達(dá)波發(fā)射到接收的間隔時(shí)間。雷達(dá)料位計(jì)具有低維護(hù)，高性能、高精度、高可靠性，使用壽命長(zhǎng)等優(yōu)點(diǎn)。泰州水滴型雷達(dá)料位計(jì)廠家直供</p><p
