超聲波流量計原裝進(jìn)口聚合物電池,鉅大電子公司是專業(yè)的聚合物電池生產(chǎn)廠家。
不同型號(特別是不同體積)的電池,他的容量越高,提供使用的時間越長.拋開體積和重量的因素,當(dāng)然容量越高越好. 但是同樣的電池型號,標(biāo)稱容量(比如600mAh)也相同,鋰離子電池實(shí)際測的初始容量不同:比如一個為660mAh,另一個是605mAh,那么660mAh的就比605mAh的好嗎. 實(shí)際情況可能是容量高的是因?yàn)殡姌O材料中多了增加初始容量的東西,而減少了電極穩(wěn)定用的東西,其結(jié)果就是循環(huán)使用幾十次以后,容量高的電池迅速容量衰竭,而容量低的電池卻依然堅(jiān)挺.許多國內(nèi)的電芯廠家往往以這個方式來獲得高容量的電池.而用戶使用半年以后待機(jī)時間卻是差得一塌糊涂. 民用的那些AA鎳氫電池(就是五號電池),一般18650鋰電池是1400mAh,卻也有標(biāo)超高容量的(1600mAh),道理也是一樣. 其實(shí):提高容量的代價就是犧牲循環(huán)壽命,廠家不在電池材料的改性上下文章,是不可能真正"提高"電池容量的

測量原理: 電磁流量傳感器是基于法拉第電磁感應(yīng)定律而制成的,只是其中切割磁力線的導(dǎo)體不是一般的金屬而是具有一定電導(dǎo)率的液態(tài)流體或液固兩相流體。被測量的導(dǎo)電介質(zhì)在磁場中作切割磁力線運(yùn)動時,導(dǎo)電介質(zhì)中會產(chǎn)生感應(yīng)電動勢,感應(yīng)電動勢由一對電極檢測,該電壓信號VE可用下式表示: | ||

性能特點(diǎn)
技術(shù)亮點(diǎn)一、采用超大進(jìn)料口,保證物料均勻下沉、穩(wěn)定受控、不塌倉、不蓬料、不竄料。
技術(shù)亮點(diǎn)二、轉(zhuǎn)速慢,有效的延長的設(shè)備使用壽命。
技術(shù)亮點(diǎn)三、機(jī)體左右法蘭與軸之間的密封采用德國BASS公司的油浸密封形式,密封嚴(yán)密可靠。
技術(shù)亮點(diǎn)四、減速電機(jī)采用直聯(lián)方式,安裝簡單,維護(hù)方便。
技術(shù)亮點(diǎn)五、采用雙電機(jī)并聯(lián)獨(dú)立驅(qū)動方式,可以根據(jù)流量大小,選擇單電機(jī)驅(qū)動或雙電機(jī)驅(qū)動,流量調(diào)節(jié)范圍更寬,耗電小,環(huán)保節(jié)能。
工作原理
雙聯(lián)穩(wěn)流鎖料器(國家專利:0257386.0)由兩臺減速電機(jī)帶動兩臺加長葉輪向內(nèi)旋轉(zhuǎn),使物料由料倉兩側(cè)進(jìn)料,使物料均勻下沉,解決了料倉出口小,容易產(chǎn)生蓬料、坍倉等現(xiàn)象,物料通過旋轉(zhuǎn)的葉輪,連續(xù)、均勻的將物料喂送到下一設(shè)備中,通過變頻器改變電機(jī)轉(zhuǎn)速調(diào)節(jié)物料的流量。由于進(jìn)料口非常大,所以葉輪運(yùn)轉(zhuǎn)非常慢,大大延長了設(shè)備使用壽命。管壁內(nèi)側(cè)采用特殊耐磨材料處理,和葉片之間的間隙非常小,有效的檔住物料,保證長期運(yùn)行不磨損,同時,該耐磨材料具有一定的彈性,當(dāng)物料中有大顆粒進(jìn)入葉片和管壁之間時,可以輕松的將物料帶過去,而不會將電機(jī)卡死,燒毀電機(jī)。該設(shè)備具有密封性能優(yōu)越、給料均勻穩(wěn)定、卸料運(yùn)行平穩(wěn)、流量調(diào)節(jié)范圍寬、噪聲低、故障少、使用壽命長、耐磨性高,維護(hù)方便。
