Hunhu hweoiri yescrew hune simba guru pakushanda kwemuchina wekuisa mafuta, oiri yakanaka ine kugadzikana kwakanaka kwe oxidation, kupatsanurwa nekukurumidza, furo rakanaka, viscosity yakakura, uye kuramba ngura kwakanaka, saka, mushandisi anofanira kusarudza oiri chaiyo chaiyo yescrew. Kuchinja oiri kwekutanga kunoitwa mushure memaawa mazana mashanu ekushanda kwemuchina mutsva, uye oiri itsva inotsiviwa maawa maviri ega ega mushure mekushanda. Zvakanakisisa kuchinja firita yeoiri panguva imwe chete. Shandisa munzvimbo dzakaoma kupfupisa kutenderera kwekutsiva. Nzira yekutsiva: Tanga compressor yemhepo womhanya kwemaminitsi mashanu, kuitira kuti tembiricha yeoiri ikwire kusvika kupfuura 50 ℃, uye viscosity yeoiri iderere. Mira kushanda. Kana kumanikidzwa kwebhare reoiri negasi kuri 0.1Mpa, vhura vharuvhu yekudonhedza oiri pasi pebhare reoiri negasi wobatanidza tangi rekuchengetera oiri. Vharuvhu yekudonhedza oiri inofanira kuvhurwa zvishoma nezvishoma kudzivirira kupararira kweoiri nekumanikidzwa nekupisa. Kana oiri yatanga kudonha, vhara vharuvhu yekudonhedza oiri. Bvisa firita yemafuta, dururira mafuta ekuzora mumapaipi, wotsiva firita yemafuta neimwe itsva. Vhura purasitiki yekuputira, isa mafuta matsva, isa mafuta mukati mechiratidzo chemafuta, simbisa purasitiki yekuputira, tarisa kana paine kubuda kwemvura. Mafuta ekuzora mukushandiswa kwemaitiro acho anofanira kuongororwa nguva nenguva, zvikaonekwa kuti mutsetse wemafuta wakaderera zvakanyanya unofanirwa kuzadzwazve nenguva, kushandiswa kwemafuta ekuzora kunofanirawo kuburitsa condensate, kazhinji kacho kuburitswa kamwe chete pasvondo, kana mamiriro ekunze akanyanya kupisa kunofanira kuburitswa kamwe chete kwemazuva 2-3. Mira kwemaawa anopfuura mana, kana pasina kumanikidzwa mubhareni remafuta negasi, vhura vharuvhu yemafuta, buritsa condensate, ona mafuta eorganic achibuda, vhara vharuvhu nekukurumidza. Mafuta ekuzora anorambidzwa zvachose kusanganiswa nemhando dzakasiyana, usashandise mafuta ekuzora anopfuura nguva yakatarwa, zvikasadaro mhando yemafuta ekuzora inoderera, mafuta ekuzora haana kunaka, flash point inodzikira, zviri nyore kukonzera kudzimwa kwekupisa kwakanyanya, zvichikonzera kupisa kwemafuta.
