潤滑脂滴點檢測流程

 1、檢查儀(yi)器(qi)中(zhong)油浴界面是否(fou)符合要(yao)求，儀(yi)器(qi)運轉是否(fou)正常，填(tian)寫試驗臺賬;2、儀(yi)器(qi)正常后開始(shi)試驗，填(tian)寫原始(shi)記錄表(biao)頭部分(fen);3、調節溫度計(ji)位(wei)置，使浴中(zhong)的溫度計(ji)水(shui)銀球位(wei)置與試驗試管中(zhong)溫度計(ji)的位(wei)置高度在(zai)一一個水(shui)平面上;4、取(qu)試樣(yang)(不能取(qu)表(biao)面試樣(yang))將試樣(yang)裝滿(man)脂杯用刮刀除

去多余試(shi)(shi)(shi)(shi)樣(yang)。從杯(bei)底小孔將金屬(shu)棒插入(ru)，旋轉(zhuan)向上伸出，帶出試(shi)(shi)(shi)(shi)樣(yang)，將帶出試(shi)(shi)(shi)(shi)樣(yang)去除，使脂(zhi)(zhi)杯(bei)內側留下(xia)厚(hou)度(du)(du)(du)(du)可重(zhong)復的(de)(de)光滑脂(zhi)(zhi)膜;5、將脂(zhi)(zhi)杯(bei)和溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)計(ji)放入(ru)試(shi)(shi)(shi)(shi)管(guan)(guan)中(zhong)，把(ba)試(shi)(shi)(shi)(shi)管(guan)(guan)掛在油(you)(you)(you)浴(yu)(yu)中(zhong)。使油(you)(you)(you)面(mian)距試(shi)(shi)(shi)(shi)管(guan)(guan)邊(bian)緣不超過6mm;6、開(kai)啟電源(yuan)開(kai)關，攪拌油(you)(you)(you)浴(yu)(yu)，按4-70C/min的(de)(de)速度(du)(du)(du)(du)升(sheng)溫(wen)(wen)(wen)(wen)(wen)，直到油(you)(you)(you)浴(yu)(yu)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)比預期滴(di)點(dian)約低170C的(de)(de)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)。然后降(jiang)低加熱(re)速度(du)(du)(du)(du)，使試(shi)(shi)(shi)(shi)管(guan)(guan)里的(de)(de)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)與油(you)(you)(you)浴(yu)(yu)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)差值在20C或低于20C范圍內，繼續(xu)加熱(re)，以(yi)1-1. 50C/min的(de)(de)速度(du)(du)(du)(du)加熱(re)油(you)(you)(you)浴(yu)(yu)，使其溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)差維持(chi)在1-20C之間。當溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)繼續(xu)升(sheng)高試(shi)(shi)(shi)(shi)樣(yang)逐漸從脂(zhi)(zhi)杯(bei)中(zhong)露(lu)出從脂(zhi)(zhi)杯(bei)中(zhong)滴(di)出滴(di)1滴(di)流體(ti)時，立即記錄兩(liang)個(ge)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)計(ji)上的(de)(de)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)。兩(liang)個(ge)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)計(ji)讀數(shu)的(de)(de)平均值即為測試(shi)(shi)(shi)(shi)結果;7、填寫原始記錄及化(hua)驗(yan)報告(gao)單;8、清理試(shi)(shi)(shi)(shi)驗(yan)臺(tai)面(mian)及儀器(qi)。
