產(chǎn)品詳情
為了保證變送器測量管內(nèi)充滿被測介質(zhì),變迭器垂直安,流向自下而上.尤其是對于液固兩相流,必須垂直安.若現(xiàn)場只允許水平安,則必須保證兩電極在同一水平面。變送器兩端應(yīng)閥門和旁路。電磁流量變送器的電極所測出的幾毫伏交流電勢,是以變送器內(nèi)液體電位為基礎(chǔ)的.為了使液體電位穩(wěn)定并位變送器與流體保持等電位,以保證穩(wěn)定地進(jìn)行測量,變送器外殼與金屬管兩端應(yīng)有良好的接地,轉(zhuǎn)換器外殼也應(yīng)接地.接地電阻不能大于1,不能與其它電器設(shè)備的接地線共用。

使用壓縮空氣吹掃探頭必須保證壓縮空氣中不含有水分,即對所采用的壓縮空氣必須進(jìn)行氣水分離處理。化鋯測氧儀的使用和維護(hù)5.1連接加熱控制采樣檢測式探頭只有在氧化鋯測氧儀連接了加熱控制后才能正常工作,冷態(tài)下輸出的是隨機(jī)信號(hào),不代表任何意義。氧化鋯測氧儀在接人加熱控制后,在室溫條件下既可以開始正常的氣體檢測。一般探頭調(diào)零是在室溫下,加熱探頭后,通過對空氣的測量,用數(shù)字萬用表測量此時(shí)探頭輸出毫伏值,此數(shù)值就是該探頭的零位偏差數(shù)值,在顯示儀表中需要加入該零位偏差來修正儀表顯示的氧濃度。2新或更換氧化鋯測氧儀時(shí)的注意事項(xiàng)新或更換氧化鋯測氧儀時(shí),均應(yīng)校正氧分析儀的氧濃度顯示值。不進(jìn)行此項(xiàng)工作,更換新的傳感器后,檢測的氧濃度可能會(huì)與實(shí)際濃度產(chǎn)生偏差,從而影響測量精度。3氧濃度的修正原理及方法氧傳感器直接測量輸出的是被測氣體的濃度與標(biāo)準(zhǔn)空氣差電勢數(shù)值,稱為氧電勢。該電勢數(shù)值在零點(diǎn)(即空氣測量)時(shí),不同的探頭起始輸出電勢就存在偏差,而輸出電勢經(jīng)過模型轉(zhuǎn)換輸出氧濃度時(shí)也可能存在誤差。

一直以來,冷軋薄板是目前主要短缺鋼材品種,數(shù)量和質(zhì)量都不能滿足要求。大部分板材深加工生產(chǎn)原料供給不足,對于產(chǎn)品質(zhì)量要求嚴(yán)格的普冷板及鍍鋅板,目前主要依賴進(jìn)口,表面質(zhì)量、強(qiáng)度級(jí)強(qiáng)要求嚴(yán)格的轎車面板進(jìn)口的比例則更高,供需矛盾非常大。而廣東省是冷軋薄板主要消費(fèi)區(qū)域之一,且板材生產(chǎn)能力遠(yuǎn)不能滿足市場需求,缺口尤其嚴(yán)重。數(shù)據(jù)顯示,預(yù)計(jì)212年珠三角地區(qū)將消耗板材超1萬噸;廣州汽車工業(yè)將消耗高質(zhì)量要求的普冷板及鍍鋅板超過1萬噸、消耗轎車面板2萬噸,缺口很大。
