style="font-size:18px;">壓力控制器國內(nèi)現(xiàn)狀</span> </h1> <p> <span style="font-size:18px;">由于國內(nèi)工業(yè)日益增多，導(dǎo)致壓力控制器市場逐漸泛濫，民用工用使用情況混合。事實上，要生產(chǎn)出質(zhì)量的壓力控制器并不是一件很簡單的事。</span> </p> <p> <span style="font-size:18px;">首先是<strong><span style="color:#E53333;">選材</span></strong>，其次是生產(chǎn)過程的工藝控制；質(zhì)量精度較差控制器普遍表現(xiàn)在結(jié)構(gòu)形式上面，國產(chǎn)壓力控制器定制，純觸點表現(xiàn)為精度較差。控制器動作呆滯不給出信號，國產(chǎn)壓力控制器定制，民用控制器做工業(yè)使用，使用周期短，國產(chǎn)壓力控制器定制，性能不穩(wěn)定，耐壓低。如果希望壓力控制器安裝后能可靠的工作，一定要挑選<strong><span style="color:#E53333;">正規(guī)的廠家</span></strong>購買壓力控制器。</span> 如何挑選合適的壓力控制器？國產(chǎn)壓力控制器定制</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="國產(chǎn)壓力控制器定制,壓力控制器" src="http://tyunfile.71360.com/UploadFile/kytdck/637221030924130859/9668393.jpg"></div><h1> <span style="font-size:16px;">現(xiàn)場壓力校驗儀器的選擇標(biāo)準(zhǔn)</span> </h1> <p> <span style="font-size:16px;color:#E53333;"><strong>1、選擇自動化程度高的儀器</strong></span> </p> <p> <span style="font-size:16px;">首先盡量選擇能自動加壓的校驗儀器，減少人工在現(xiàn)場升降壓過程；其次選擇具有“任務(wù)管理”、數(shù)據(jù)存儲功能的校準(zhǔn)儀器，任務(wù)管理即可以實現(xiàn)在辦公室將檢定任務(wù)數(shù)據(jù)錄入校驗儀器中，省去紙質(zhì)記錄的麻煩，紙質(zhì)記錄容易出錯，后續(xù)調(diào)用、溯源比較困難。</span> </p> <p> <span style="font-size:16px;color:#E53333;"><strong>2、選擇可便攜的儀器</strong></span> </p> <p> <span style="font-size:16px;">到工業(yè)現(xiàn)場開展校準(zhǔn)工作，攜帶的校準(zhǔn)儀器不宜過重，方便攜帶，可以自供電尤佳。</span> </p> <p> <span style="font-size:16px;color:#E53333;"><strong>3、選擇可靠性高的儀器</strong></span> </p> <p> <span style="font-size:16px;">現(xiàn)場校準(zhǔn)環(huán)境復(fù)雜，需要校準(zhǔn)儀器本身具有抗電磁干擾、抗環(huán)境干擾的能力，并且具有良好的防堵、防漏、防污染能力。</span> </p> <p> <span style="font-size:16px;color:#E53333;"><strong>4、選擇多功能的儀器</strong></span> </p> <p> <span style="font-size:16px;">傳統(tǒng)壓力校準(zhǔn)解決方案由多種儀器共同組成，包括壓力源、標(biāo)準(zhǔn)表、萬用表、手操器等，集成以上功能的壓力校準(zhǔn)儀器，可以實現(xiàn)現(xiàn)場壓力儀表的輕松校準(zhǔn)工作。</span> 國產(chǎn)壓力控制器定制壓力控制器的組成有哪些？</p><div

style="font-size:18px;">檢查傳感器器密封圈，一般是因為密封圈規(guī)格原因(太軟或太厚)，傳感器擰緊時，密封圈被壓縮到傳感器引壓口里面堵塞傳感器，加壓時壓力介質(zhì)進(jìn)不去，但是壓力很大時突然沖開密封圈，壓力傳感器受到壓力而變化，而壓力再次降低時，密封圈又回位堵住引壓口，殘存的壓力釋放不出，。</span> </p> <p> <span

style="font-size:16px;">3、安裝電纜時，應(yīng)選擇合適的電纜外徑，并將電纜引入處的壓緊的螺母擰緊，以免電纜松動，并防止水或灰塵的滲入。</span> </p> <p> <span style="font-size:16px;">4、對于有壓力峰值及脈沖壓力的受控液體介質(zhì)，可在控制器的接口上安裝一個壓力沖擊阻尼器，以消除不利影響。</span> </p> <p> <span style="font-size:16px;">5、通斷電流不能大于額定值。</span> </p> <p> <span style="font-size:16px;">6、安裝（或拆卸）控制器時要特別注意：</span> </p> <p> <span style="font-size:16px;">1）安裝（或拆卸）必須用扳手夾持傳感器的平面部份，防止傳感器和開關(guān)殼體發(fā)生相對轉(zhuǎn)動。</span> </p> <p> <span style="font-size:16px;">2）當(dāng)傳感器接口為內(nèi)螺紋時，管道接頭旋入傳感器內(nèi)深度不可超過12mm。</span>
