工業冷水機在應用的過程中(zhong)有很多標準與規定，那(nei)么在工業冷水機運(yun)行的過程中(zhong)有哪些重要技術指標呢？

  工業冷(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)水機(ji)(ji)(ji)機(ji)(ji)(ji)油具有(you)潤滑、冷(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)卻、沖洗、密封等功能，是制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)壓縮(suo)機(ji)(ji)(ji)不(bu)可或缺的重要(yao)組分。壓縮(suo)機(ji)(ji)(ji)內部(bu)的冷(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)凍機(ji)(ji)(ji)油會不(bu)可避(bi)免(mian)地隨著壓縮(suo)機(ji)(ji)(ji)排氣(qi)混入制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)系統(tong)。過量和油循環(huan)(huan)率(lv)會對(dui)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)壓縮(suo)機(ji)(ji)(ji)的運行可靠性造成嚴(yan)(yan)重危(wei)險，并且對(dui)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)循環(huan)(huan)也帶來負面作(zuo)用，因(yin)此，制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)循環(huan)(huan)的油循環(huan)(huan)率(lv)不(bu)論是制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)壓縮(suo)機(ji)(ji)(ji)還是工業冷(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)水機(ji)(ji)(ji)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)系統(tong)，都是一個重要(yao)技(ji)術指標(biao)，需要(yao)嚴(yan)(yan)格控制(zhi)(zhi)(zhi)。

  稱(cheng)重(zhong)法，我國(guo)現行(xing)(xing)國(guo)家標準(zhun)GB/T5773、多(duo)數(shu)國(guo)外(wai)標準(zhun)規定的(de)制(zhi)(zhi)(zhi)冷壓(ya)縮機(ji)(ji)用(yong)(yong)冷凍機(ji)(ji)油(you)循(xun)環率的(de)測(ce)(ce)定采(cai)(cai)用(yong)(yong)的(de)都是稱(cheng)重(zhong)法，即使批(pi)量(liang)(liang)方(fang)式對冷凝制(zhi)(zhi)(zhi)冷劑中的(de)油(you)量(liang)(liang)進行(xing)(xing)抽(chou)取稱(cheng)重(zhong)測(ce)(ce)定：用(yong)(yong)采(cai)(cai)樣容器(qi)從(cong)制(zhi)(zhi)(zhi)冷系統(tong)中抽(chou)出一(yi)部分制(zhi)(zhi)(zhi)冷劑和油(you)的(de)混(hun)(hun)合物，之后(hou)緩(huan)慢(man)蒸發出采(cai)(cai)樣容器(qi)里面(mian)的(de)制(zhi)(zhi)(zhi)冷劑，對采(cai)(cai)樣容器(qi)重(zhong)量(liang)(liang)的(de)變化(hua)進行(xing)(xing)稱(cheng)重(zhong)測(ce)(ce)量(liang)(liang)，因(yin)而得出稱(cheng)重(zhong)前后(hou)采(cai)(cai)樣容器(qi)中混(hun)(hun)合物的(de)重(zhong)量(liang)(liang)變化(hua)數(shu)據，計算得出低溫工業冷水機(ji)(ji)制(zhi)(zhi)(zhi)冷系統(tong)的(de)含油(you)量(liang)(liang)。進行(xing)(xing)稱(cheng)重(zhong)測(ce)(ce)量(liang)(liang)時，要求(qiu)測(ce)(ce)量(liang)(liang)工況按(an)有關制(zhi)(zhi)(zhi)冷劑壓(ya)縮機(ji)(ji)產品標準(zhun)或規定進行(xing)(xing)運(yun)轉至穩(wen)定狀態。

  油(you)(you)(you)(you)分(fen)離(li)法，使(shi)用輔助(zhu)油(you)(you)(you)(you)分(fen)離(li)器(qi)(qi)進行油(you)(you)(you)(you)循環(huan)率的(de)測量方法原(yuan)理如下(xia)：在制冷劑(ji)壓(ya)縮(suo)機排氣(qi)管側裝一個油(you)(you)(you)(you)分(fen)離(li)器(qi)(qi)，壓(ya)縮(suo)機排氣(qi)經(jing)過油(you)(you)(you)(you)分(fen)離(li)器(qi)(qi)時，排氣(qi)混合物中(zhong)的(de)潤滑油(you)(you)(you)(you)被分(fen)離(li)出(chu)來，并收集(ji)到(dao)帶油(you)(you)(you)(you)觀察鏡的(de)器(qi)(qi)皿中(zhong)，根據容器(qi)(qi)中(zhong)油(you)(you)(you)(you)量。的(de)變(bian)(bian)化以及(ji)制冷劑(ji)循環(huan)量，可以計算出(chu)油(you)(you)(you)(you)循環(huan)率的(de)大小。這種方法的(de)優點(dian)是(shi)能監(jian)測到(dao)不同時間油(you)(you)(you)(you)循環(huan)率的(de)變(bian)(bian)化。但是(shi)，需要注意一點(dian)：由(you)于潤滑油(you)(you)(you)(you)被收集(ji)到(dao)觀察器(qi)(qi)中(zhong)，壓(ya)縮(suo)機里面的(de)油(you)(you)(you)(you)面降低，壓(ya)縮(suo)機的(de)出(chu)油(you)(you)(you)(you)量有下(xia)降趨(qu)勢。
