產(chǎn)品詳情
一般說(shuō)來(lái)由于工業(yè)生產(chǎn)中工質(zhì)的溫度常不能保持恒定,故多采用頻差法及時(shí)差法。只有在管徑很大時(shí)才采用直接時(shí)差法。對(duì)換能器安裝方法的選擇原則一般是:當(dāng)流體沿管軸平行流動(dòng)時(shí),選用Z法;當(dāng)流動(dòng)方向與管鈾不平行或管路安裝地點(diǎn)使換能器安裝間隔受到限制時(shí),采用V法或X法。當(dāng)流場(chǎng)分布不均勻而表前直管段又較短時(shí),也可采用多聲道(雙聲道或四聲道)來(lái)克服流速擾動(dòng)帶來(lái)的流量測(cè)量誤差。多普勒法適于測(cè)量?jī)上嗔?,可避免常?guī)儀表由懸浮?;驓馀菰斐傻亩氯?、磨損、附著而不能運(yùn)行的弊病,因而得以迅速發(fā)展。
直線振動(dòng)篩總之,膠帶調(diào)偏是一件比較麻煩的事情,影響膠帶跑偏的因素很多,需要仔細(xì)觀察,分析原因,然后對(duì)癥下藥。調(diào)偏工作也需要在實(shí)踐中摸索經(jīng)驗(yàn),積累經(jīng)驗(yàn)。單電機(jī)傳動(dòng)時(shí),液力偶合器的充液量為9升,雙電機(jī)傳動(dòng)時(shí)為了保證兩電機(jī)的實(shí)際功率分配相接近,必須通過(guò)調(diào)正來(lái)確定合理的充液量使兩電機(jī)的實(shí)際功率(或電流)之比接近于4/4的比值。
一般的交-直-交電壓型變頻器的主電路輸入側(cè)是經(jīng)三相橋式不可控整流器向中間直流環(huán)節(jié)的濾波電容充電,然后通過(guò)PWM控制下的逆變器輸入到負(fù)載上。雖然這樣的電路成本低、結(jié)構(gòu)簡(jiǎn)單、可靠性高,但是由于采用三相橋式不可控整流器,使得功率因數(shù)低、網(wǎng)側(cè)諧波污染以及無(wú)法實(shí)現(xiàn)能量的再生利用等。PWM+PWM(四象限矢量控制結(jié)構(gòu))控制技術(shù)打破了過(guò)去變頻器的統(tǒng)一結(jié)構(gòu),PWM整流器和PWM逆變器通過(guò)軟硬件的調(diào)整和電抗器等附件就可實(shí)現(xiàn)系統(tǒng)的功率因數(shù)趨于1,大幅消除了網(wǎng)側(cè)諧波污染,綠色環(huán)保,并且實(shí)現(xiàn)了負(fù)載的四象限運(yùn)行,使能量雙向流動(dòng),能量轉(zhuǎn)換效率高,能滿足低壓大功率及高壓大功率的要求等特點(diǎn)已成為應(yīng)用熱點(diǎn)。
不但自帶數(shù)據(jù)庫(kù)可實(shí)現(xiàn)瞬時(shí)參數(shù)及流量的表示,以及積累流量和歷史數(shù)據(jù)的再現(xiàn);并且在儀表的運(yùn)行方面,采取了多種電源保障法子:內(nèi)電池組、太陽(yáng)能和外接電源等,實(shí)現(xiàn)了在無(wú)電力供給環(huán)境下,或是獨(dú)立自成計(jì)量零碎,就地表示人造氣瞬時(shí)流量、積累流量和數(shù)據(jù)的存儲(chǔ)、再現(xiàn)等;正常環(huán)境下可顛末現(xiàn)場(chǎng)總線和上位機(jī)連貫,履行數(shù)字旌旗燈號(hào)傳輸上傳表示,也或是在工控機(jī)上履行二次數(shù)據(jù)處理,組成的計(jì)量零碎更加靈動(dòng)、牢靠。采納這種法子,實(shí)現(xiàn)了計(jì)量數(shù)據(jù)的無(wú)憂化,使得零碎組織簡(jiǎn)單、操縱更簡(jiǎn)單、更牢靠、更容易護(hù)衛(wèi);不但或是單校也或是聯(lián)校。
