style="text-indent:25px">現(xiàn)今物位測(cè)量領(lǐng)域困擾用戶的是一些大型固體料倉(cāng)的物位測(cè)量，特別是用于50/100米以內(nèi)的充滿粉塵和擾動(dòng)的加料狀態(tài)下的料倉(cāng)。相關(guān)技術(shù)的儀表例如電容或?qū)Рɡ走_(dá)TDR在放料時(shí)物位下降時(shí)會(huì)受到很強(qiáng)的張力負(fù)載，可能會(huì)損壞儀表或把倉(cāng)頂拉塌掉。重錘經(jīng)常有埋錘的問題，需要經(jīng)常維修，大多數(shù)其他機(jī)械式儀表也是這樣。而高粉塵工況又可能會(huì)超出非接觸式超聲波物位測(cè)量系統(tǒng)的能力。高頻的調(diào)頻雷達(dá)料位計(jì)技術(shù)尤其適合這種大型固體料倉(cāng)的物位測(cè)量。高頻雷達(dá)一般為工作在K波段(24～26GHz)的雷達(dá)物位計(jì)，河北雷達(dá)料位計(jì)哪家質(zhì)量好，雷達(dá)的工作頻率越高其電磁波波長(zhǎng)越短，河北雷達(dá)料位計(jì)哪家質(zhì)量好，越容易在傾斜的固體表面有更好的反射，并具有較窄的波束寬度，可有效避開障礙物，高的頻率還可使雷達(dá)使用更小的天線。而FMCW調(diào)頻連續(xù)波微波物位計(jì)發(fā)射和接受信號(hào)是同時(shí)的，相同時(shí)間內(nèi)發(fā)射的微波信號(hào)更多，固體測(cè)量中可減少高粉塵固體料倉(cāng)測(cè)量中的失波現(xiàn)象。因此固體測(cè)量中高頻的調(diào)頻雷達(dá)能提供準(zhǔn)確、可靠的測(cè)量，并在例如化工行業(yè)中的PP粉末，河北雷達(dá)料位計(jì)哪家質(zhì)量好、PE粉末等介質(zhì)中也有良好應(yīng)用。但由于技術(shù)限制，現(xiàn)今還沒有工作在K波段以上的高頻雷達(dá)料位計(jì)。按照工作方式進(jìn)行劃分，雷達(dá)料位計(jì)又分為接觸式雷達(dá)料位計(jì)和非接觸式雷達(dá)料位計(jì)。河北雷達(dá)料位計(jì)哪家質(zhì)量好</p><div

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，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，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，對(duì)測(cè)量無影響；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。南京雙腔雷達(dá)料位計(jì)廠家哪家好雷達(dá)料位計(jì)可以適應(yīng)高溫、高壓、蒸汽等惡劣的生產(chǎn)環(huán)境。</p><div

(1)回波處理新技術(shù)的應(yīng)用從雷達(dá)料位計(jì)的測(cè)量原理可以知道，雷達(dá)料位計(jì)是通過處理雷達(dá)波從探頭發(fā)射到介質(zhì)表面然后返回到探頭的時(shí)間來測(cè)量料位的，在反射信號(hào)中混合有許多干擾信號(hào)，所以，對(duì)真實(shí)回波的處理和對(duì)各種虛假回波的識(shí)別技術(shù)就成為雷達(dá)料位計(jì)能夠準(zhǔn)確測(cè)量的關(guān)鍵因素。(2)測(cè)量數(shù)據(jù)處理：由于液面波動(dòng)和隨機(jī)噪聲等因素的影響，檢測(cè)信號(hào)中必然混有大量噪聲。為了提高檢測(cè)的準(zhǔn)確度，必須對(duì)檢測(cè)信號(hào)進(jìn)行處理，盡可能消除噪聲。經(jīng)過大量的實(shí)驗(yàn)驗(yàn)證，采用數(shù)據(jù)平滑方法可以達(dá)到滿意的效果。此方法也可有效的克服罐內(nèi)攪拌器對(duì)測(cè)量的影響。(3)雷達(dá)料位計(jì)的特點(diǎn)：由于雷達(dá)料位計(jì)采用了上述先進(jìn)的回波處理和數(shù)據(jù)處理技術(shù)，加上雷達(dá)波本身頻率高，穿透性能好的特點(diǎn)，所以，雷達(dá)料位計(jì)具有比接觸式料位計(jì)和同類非接觸料位計(jì)更加優(yōu)良的性能。①可在惡劣條件下連續(xù)準(zhǔn)確地測(cè)量。②操作簡(jiǎn)單，調(diào)試方便。③準(zhǔn)確安全且節(jié)省能源。④無需維修且可靠性強(qiáng)。⑤幾乎可以測(cè)量所有介質(zhì)。 </p><p> 生活中雷達(dá)料位計(jì)存在的不足之處.雷達(dá)料位計(jì)基本不受氣體、真空、高溫、壓差變化、氣泡等影響，適用于易燃易爆、腐蝕性介質(zhì)液位的測(cè)量，測(cè)量精度能達(dá)到1 mm。接下來我們可以通過下面文章詳細(xì)的了解了解. </p> <p> （1）雷達(dá)料位計(jì)和差壓式液位計(jì)的測(cè)量值均反映的是垂直高度上液體的高度，因此操作人員可以通過比較雷達(dá)料位計(jì)和差壓式液位計(jì)的測(cè)量差值大小，較直接的判斷回收丁二烯貯罐內(nèi)含水量的多少，及時(shí)進(jìn)行排水操作。同時(shí)，也可給單體回收崗位反饋一定的信息：本單元工藝是否存在異?，F(xiàn)象。 </p> <p> （2）當(dāng)球罐內(nèi)液體液位在35%~75%時(shí)，公式計(jì)算的值與取樣分析值相差較小，而當(dāng)球形貯罐內(nèi)液體液位較低時(shí)，需要對(duì)測(cè)量差值進(jìn)行一定的修正。 </p> <p> （3）從目前的實(shí)踐經(jīng)驗(yàn)來看，該方法可以作為取樣分析方法的補(bǔ)充手段，不可以完全代替取樣分析。 </p> <p> （4）當(dāng)回丁純度較高時(shí)，如90%以上時(shí)，由公式估算出的回收丁二烯濃度與取樣分析值存在相對(duì)大的差值，需要改變計(jì)算方式。當(dāng)回丁純度較高時(shí)，可近似采用A /B
