提高生產(chǎn)效率，軟化水循環(huán)，無(wú)結(jié)垢、無(wú)堵塞、無(wú)損失；延長(zhǎng)設(shè)備壽命，保障設(shè)備可靠、穩(wěn)定運(yùn)行，減少故障，杜絕事故；全封閉循環(huán)、無(wú)雜質(zhì)進(jìn)入、無(wú)介質(zhì)蒸發(fā)、無(wú)污染；提高廠房利用系數(shù)，無(wú)需水池，減少占地，節(jié)省空間；占用空間小，安裝、移動(dòng)、布置方便，結(jié)構(gòu)緊湊；操作方便，運(yùn)行穩(wěn)定，自動(dòng)化程度高；節(jié)約運(yùn)行成本，多種模式自動(dòng)切換，智能控制；用途廣泛，對(duì)換熱器無(wú)腐蝕的介質(zhì)，均可直接冷卻；全壽命運(yùn)行成本低，初投資高，運(yùn)行和維護(hù)成本低。
精度提高。早期電磁流量計(jì)精度一般為±1.5%~±2.5%?，F(xiàn)在電磁流量計(jì)精度提高到±.5%~.1%。有的廠商已做±.2%的電磁流量計(jì)。勵(lì)磁方式改變。由早使用的交流工頻（5Hz）正弦波勵(lì)磁，改變?yōu)榈皖l矩形波勵(lì)磁（6.25Hz）。近開發(fā)的產(chǎn)品則采用雙頻波勵(lì)磁（低頻矩形波6.25Hz+高頻矩形波75Hz）。交流工頻勵(lì)磁是利用市電作為勵(lì)磁電源，電源頻率不穩(wěn)定，在測(cè)量電極上會(huì)產(chǎn)生一種磁通微分噪聲，使儀表零點(diǎn)漂移。
不銹鋼圓弧泵維護(hù)及檢查YCB系列不銹鋼圓弧齒輪泵在運(yùn)行過(guò)程中，軸承溫度不能超過(guò)環(huán)境溫度35℃，高溫度不得超過(guò)8℃。開動(dòng)電機(jī)，當(dāng)YCB系列不銹鋼圓弧齒輪泵正常運(yùn)轉(zhuǎn)后，打開出口壓力表和進(jìn)口真空泵視其顯示出適當(dāng)壓力后，逐漸打開閘閥，同時(shí)檢查電機(jī)負(fù)荷情況。YCB系列不銹鋼圓弧齒輪泵管路及結(jié)合處有無(wú)松動(dòng)現(xiàn)象.用手轉(zhuǎn)動(dòng)圓弧齒輪泵試看泵是否靈活。點(diǎn)動(dòng)電機(jī)，試看電機(jī)轉(zhuǎn)向是否正確。盡量控制YCB系列不銹鋼圓弧泵的流量和揚(yáng)程在標(biāo)牌上注明的范圍內(nèi)，以保證齒輪泵在率點(diǎn)運(yùn)轉(zhuǎn)，才能獲得大的節(jié)能效果。
不同種類管材有哪種點(diǎn)焊裝卡式耐磨管點(diǎn)焊裝卡式耐磨管是用耐高溫粘膠將中間帶孔的氧化鋁陶瓷片粘貼在管道內(nèi)壁，同時(shí)配合點(diǎn)焊工藝透過(guò)小孔將陶瓷牢固地焊接在鋼管內(nèi)壁。為保護(hù)焊點(diǎn)，上面再旋上陶瓷蓋帽。每塊瓷片不但互壓互插，而且每塊瓷都形成梯形角度，使瓷塊之間緊密連接，無(wú)縫隙；當(dāng)一圈的后一塊緊密嵌入后，瓷塊之間形成36的機(jī)械自鎖力（這種技巧在幾個(gè)世紀(jì)前就被運(yùn)用在橋梁建筑工程上）。每塊瓷片不但互壓互插，而且每塊瓷都形成梯形角度，使瓷塊之間緊密連接，無(wú)縫隙；該種產(chǎn)品制作工藝相對(duì)復(fù)雜，制作周期較長(zhǎng)，成本較高。
