style="text-indent:25px">減溫減壓裝置檢查、自控:按現(xiàn)場接線圖檢查各現(xiàn)場傳感器（壓力變送器、熱電阻、流量傳感器）、執(zhí)行機(jī)構(gòu)、水泵與控制柜間接線是否正確。檢查進(jìn)出口熱電阻及壓力變送器前后是否裝反，壓力變送器量程高的為進(jìn)口，量程低的為出口。水泵通電前必須注滿水將全部空氣排出，以免空運(yùn)轉(zhuǎn)將水泵機(jī)械密封燒壞。在確認(rèn)水泵注滿水后，給水泵通電，檢查水泵是否正轉(zhuǎn)。如反轉(zhuǎn)，關(guān)閉水泵將任意兩相電源調(diào)換即可。檢查完畢關(guān)閉水泵。檢查儀表設(shè)定是否正確，接通儀表電源，檢查所有盤上儀表的上下限是否跟現(xiàn)場傳感器量程一致，PID儀表目標(biāo)值設(shè)定是否合理，PID儀表的正反作用（壓力調(diào)節(jié)閥正裝時(shí)調(diào)節(jié)儀表應(yīng)設(shè)反作用，反裝時(shí)應(yīng)設(shè)正作用。如果水質(zhì)不清潔，含有一些雜質(zhì)，必須在減溫減壓裝置的上游進(jìn)水口安裝過濾器。</p><div

style="text-indent:25px">減溫減壓裝置是由哈爾濱鍋爐廠于二十世紀(jì)五十年代從前蘇聯(lián)引入國內(nèi)。發(fā)展到現(xiàn)在，大體可分為三代產(chǎn)品。第三代減溫減壓裝置為第二代的換代產(chǎn)品：減溫減壓閥內(nèi)部改為多級(jí)套筒式省去了節(jié)流孔板，同時(shí)多級(jí)套筒的節(jié)流小孔還起到消音的作用。減溫減壓閥與給水調(diào)節(jié)閥采用變流量系數(shù)設(shè)計(jì)的方法。該設(shè)計(jì)形式的特點(diǎn)就是設(shè)計(jì)與使用相吻合，從0到100%全程可調(diào)節(jié)，該設(shè)計(jì)方法于2003年12月被國家科委授予應(yīng)用型發(fā)明獎(jiǎng)。由于給水調(diào)節(jié)閥能夠適用于各種壓差，在減溫系統(tǒng)中取消了節(jié)流閥或節(jié)流裝置。第三代產(chǎn)品不僅具備第二代產(chǎn)品的所有優(yōu)點(diǎn)，同時(shí)還彌補(bǔ)第二代產(chǎn)品中的所有不足之處：減壓，并多級(jí)同步調(diào)節(jié)提高了調(diào)節(jié)范圍；采用同步可調(diào)噴咀在閥內(nèi)噴水，提高了霧化效果。減溫系統(tǒng)采用文丘里氏加笛管噴嘴的方式，無傳動(dòng)部件，減溫水霧化效果好，噴嘴拆裝方便，便于維修。合肥減溫減壓裝置哪里有</p><p
