參數(shù)不穩(wěn)定的煙氣余熱鍋爐煙氣在流量、溫度、成份組成、含塵量等各方面的波動(dòng)是其特征之一,波動(dòng)的性質(zhì)可以是有規(guī)律的、周期性的,也可以是非規(guī)律性、非周期性的;波動(dòng)的特點(diǎn)可以是漸進(jìn)性的、也可以是沖擊性的;可以是單一參數(shù)的,也可以是多參數(shù)的復(fù)合性波動(dòng)。余熱鍋爐的選型必須首先分析主工藝流程的整個(gè)周期,確定周期中各個(gè)時(shí)間區(qū)段的煙氣特點(diǎn),從而在余熱鍋爐設(shè)計(jì)中逐個(gè)落實(shí)相應(yīng)的措施。其中突出的特點(diǎn)往往是余熱鍋爐選型的主要根據(jù)。
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。

【軟水設(shè)備工作原理及日常運(yùn)作:】軟水機(jī)在控制頭那位置有一個(gè)入水口,一個(gè)出水口。將入水口接在水表后面,總出水口,這樣,流出來的水就全部是軟化過的水了,所有生活用水都解決了。軟水機(jī)罐子里面裝的是樹脂,透明黃色小顆粒。軟水機(jī)就是靠樹脂去吸附水中的鈣美離子(水堿),當(dāng)樹脂達(dá)到一定飽和度的時(shí)候要靠濃鹽水將水中的鈣鎂離子置換出去,恢復(fù)樹脂的吸附功能(這個(gè)就叫再生),再生的時(shí)候是需要無碘鹽的,平時(shí)正常運(yùn)行的時(shí)候沒有廢水,一個(gè)月鹽錢大約需要1塊錢左右,全自動(dòng)的軟水機(jī)一個(gè)月多耗電3度后主管道上,安裝在廚柜內(nèi)或用戶位置。

PLC
處理器(CPU)由控制器、運(yùn)算器和寄存器組成并集成在一個(gè)芯片內(nèi)。CPU通過數(shù)據(jù)總線總線、地址總線、控制總線和電源總線與存儲(chǔ)器、輸入輸出接口、編程器和電源相連接。
小型PLC的CPU采用8位或16位微處理器或單片機(jī),如8031、M68000等,這類芯片價(jià)格很低;中型PLC的CPU采用16位或32位微處理器或單片機(jī),如8086、96系列單片機(jī)等,這類芯片主要特點(diǎn)是集成度高、運(yùn)算速度快且可靠性高;而大型PLC則需采用高速位片式微處理器。
CPU按照PLC內(nèi)系統(tǒng)程序賦予的功能指揮PLC控制系統(tǒng)完成各項(xiàng)工作任務(wù)
