潤滑脂滴點測試方法

測(ce)(ce)定(ding)(ding)(ding)滴(di)點(dian)(dian)的(de)方法(fa)有三種:潤(run)滑(hua)(hua)脂和(he)固體經滴(di)點(dian)(dian)測(ce)(ce)定(ding)(ding)(ding)法(fa)SH/T 0115-92、潤(run)滑(hua)(hua)脂滴(di)點(dian)(dian)測(ce)(ce)定(ding)(ding)(ding)法(fa)GB/T4929-85和(he)潤(run)滑(hua)(hua)脂寬(kuan)溫度范圍滴(di)點(dian)(dian)測(ce)(ce)定(ding)(ding)(ding)法(fa)GB/T3498-83。前兩種方法(fa)只能測(ce)(ce)定(ding)(ding)(ding)250°G以下(xia)的(de)滴(di)點(dian)(dian)，而(er)后(hou)者可測(ce)(ce)定(ding)(ding)(ding)高達330C的(de)各(ge)種類(lei)型潤(run)滑(hua)(hua)脂的(de)滴(di)點(dian)(dian)。國(guo)(guo)外(wai)相應測(ce)(ce)定(ding)(ding)(ding)潤(run)滑(hua)(hua)脂滴(di)點(dian)(dian)的(de)方法(fa)有:美國(guo)(guo)的(de)ASTM D566、ASTM D2265（寬(kuan)溫法(fa)）、德國(guo)(guo)的(de)DIN 51801和(he)日本的(de)JIS K22205.4等(deng)。

自動(dong)潤(run)滑(hua)脂(zhi)寬溫(wen)度范圍滴(di)點(dian)測定(ding)儀(yi)按照標(biao)準(zhun)規定(ding)的(de)試(shi)驗方法自動(dong)測定(ding)潤(run)滑(hua)脂(zhi)從脂(zhi)杯中滴(di)落(luo)第一滴(di)并到(dao)達試(shi)管底部時(shi)的(de)溫(wen)度。
