工(gong)(gong)業冷水(shui)機(ji)在應(ying)用的過程(cheng)(cheng)中有很多標準與規定，那(nei)么(me)在工(gong)(gong)業冷水(shui)機(ji)運(yun)行的過程(cheng)(cheng)中有哪些重要(yao)技術指標呢(ni)？

  工業(ye)冷(leng)(leng)水機(ji)機(ji)油(you)具有(you)潤滑(hua)、冷(leng)(leng)卻、沖洗、密(mi)封等功能，是(shi)制(zhi)冷(leng)(leng)壓(ya)縮機(ji)不(bu)可(ke)或缺的(de)(de)重(zhong)要(yao)組分。壓(ya)縮機(ji)內部(bu)的(de)(de)冷(leng)(leng)凍機(ji)油(you)會不(bu)可(ke)避免地隨著(zhu)壓(ya)縮機(ji)排氣(qi)混(hun)入制(zhi)冷(leng)(leng)系統(tong)。過量(liang)和(he)油(you)循(xun)(xun)環(huan)率會對(dui)制(zhi)冷(leng)(leng)壓(ya)縮機(ji)的(de)(de)運(yun)行可(ke)靠性造成嚴重(zhong)危險(xian)，并(bing)且對(dui)制(zhi)冷(leng)(leng)循(xun)(xun)環(huan)也(ye)帶來負面(mian)作用，因此，制(zhi)冷(leng)(leng)循(xun)(xun)環(huan)的(de)(de)油(you)循(xun)(xun)環(huan)率不(bu)論是(shi)制(zhi)冷(leng)(leng)壓(ya)縮機(ji)還是(shi)工業(ye)冷(leng)(leng)水機(ji)制(zhi)冷(leng)(leng)系統(tong)，都是(shi)一個重(zhong)要(yao)技術指標，需要(yao)嚴格(ge)控制(zhi)。

  稱重(zhong)(zhong)(zhong)(zhong)法，我(wo)國現(xian)行國家標準(zhun)GB/T5773、多(duo)數(shu)國外標準(zhun)規定(ding)的(de)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)壓縮機(ji)(ji)用冷(leng)(leng)(leng)(leng)(leng)凍機(ji)(ji)油(you)(you)循環率的(de)測(ce)定(ding)采(cai)用的(de)都是稱重(zhong)(zhong)(zhong)(zhong)法，即使批(pi)量(liang)(liang)方式(shi)對冷(leng)(leng)(leng)(leng)(leng)凝制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)劑(ji)中(zhong)的(de)油(you)(you)量(liang)(liang)進(jin)(jin)行抽取稱重(zhong)(zhong)(zhong)(zhong)測(ce)定(ding)：用采(cai)樣容器(qi)(qi)從制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)系統中(zhong)抽出(chu)一(yi)部分(fen)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)劑(ji)和(he)油(you)(you)的(de)混合物，之后(hou)緩慢(man)蒸發(fa)出(chu)采(cai)樣容器(qi)(qi)里面的(de)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)劑(ji)，對采(cai)樣容器(qi)(qi)重(zhong)(zhong)(zhong)(zhong)量(liang)(liang)的(de)變化(hua)進(jin)(jin)行稱重(zhong)(zhong)(zhong)(zhong)測(ce)量(liang)(liang)，因而得(de)出(chu)稱重(zhong)(zhong)(zhong)(zhong)前后(hou)采(cai)樣容器(qi)(qi)中(zhong)混合物的(de)重(zhong)(zhong)(zhong)(zhong)量(liang)(liang)變化(hua)數(shu)據，計(ji)算得(de)出(chu)低(di)溫工業冷(leng)(leng)(leng)(leng)(leng)水機(ji)(ji)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)系統的(de)含油(you)(you)量(liang)(liang)。進(jin)(jin)行稱重(zhong)(zhong)(zhong)(zhong)測(ce)量(liang)(liang)時，要求(qiu)測(ce)量(liang)(liang)工況(kuang)按有關(guan)制(zhi)(zhi)(zhi)冷(leng)(leng)(leng)(leng)(leng)劑(ji)壓縮機(ji)(ji)產品標準(zhun)或規定(ding)進(jin)(jin)行運轉至穩定(ding)狀態。

  油(you)(you)分(fen)(fen)離法，使用(yong)輔助(zhu)油(you)(you)分(fen)(fen)離器(qi)進行油(you)(you)循(xun)環(huan)率的(de)(de)(de)測量方(fang)法原理(li)如下：在(zai)制(zhi)冷(leng)劑壓(ya)縮機(ji)排氣(qi)管側(ce)裝(zhuang)一個油(you)(you)分(fen)(fen)離器(qi)，壓(ya)縮機(ji)排氣(qi)經過油(you)(you)分(fen)(fen)離器(qi)時，排氣(qi)混合物中(zhong)的(de)(de)(de)潤(run)(run)滑(hua)油(you)(you)被分(fen)(fen)離出來(lai)，并收集到(dao)(dao)(dao)帶油(you)(you)觀察鏡的(de)(de)(de)器(qi)皿中(zhong)，根據(ju)容器(qi)中(zhong)油(you)(you)量。的(de)(de)(de)變(bian)化以(yi)及制(zhi)冷(leng)劑循(xun)環(huan)量，可以(yi)計算出油(you)(you)循(xun)環(huan)率的(de)(de)(de)大小(xiao)。這種方(fang)法的(de)(de)(de)優點(dian)是(shi)能監測到(dao)(dao)(dao)不(bu)同時間油(you)(you)循(xun)環(huan)率的(de)(de)(de)變(bian)化。但(dan)是(shi)，需要注意一點(dian)：由于潤(run)(run)滑(hua)油(you)(you)被收集到(dao)(dao)(dao)觀察器(qi)中(zhong)，壓(ya)縮機(ji)里面的(de)(de)(de)油(you)(you)面降(jiang)低(di)，壓(ya)縮機(ji)的(de)(de)(de)出油(you)(you)量有(you)下降(jiang)趨勢。
