I. Kev kuaj cov roj
1. Dej qib thiab mob
Chaw ua si rau cov menyuam rau theem hauv av. Kaw lub cav thiab khij cov kab xev (nws yuav tsum yog nruab nrab ntawm cov kab sab sauv thiab qis dua) rau 15 feeb.
Saib cov roj xim: feem ntau, nws yog lub teeb daj lossis xim av. Yog tias nws yog dub, cov tawv ntoo, lossis muaj cov phuam qhwv caj dab, hloov nws tam sim ntawd.
2. Cov ntxhiab thiab kev ntxhib los mos
Cov roj ib txwm yuav tsum muaj tsis muaj ntxhiab tsw. Kev hlawv lossis qaub tsw tsw muaj kev cuam tshuam tsis zoo.
Ntswj koj cov ntiv tes rau hauv cov roj me me; Nws yuav tsum tuab thiab du. Yog tias nws yog nyias lossis muaj qoob loo yooj yim, nws tsis tsim nyog.
Ii. Qhov Kev Ntsuam Xyuas Tseem Ceeb
1. Viscosity Test
Cov roj Hydraulic / iav roj yuav tsum tau ntsib Iso Viscosity Admems (piv txwv li cov qib 32/46/68 yog feem ntau siv rau roj hydraulic).
Siv Viscais ntsuas ntsuas qhov Kinematic viscosity ntawm qhov kub siab (100 degree). Yog tias qhov sib txawv tshaj plaws ± 10%, cov roj yuav tsum tau hloov . 2. tsom xam
Txheeb xyuas cov ntsiab lus noo noo (yuav tsum tsawg dua lossis sib npaug rau 0.05%) thiab kev kuaj xyuas tshuab hluav taws xob (pom kev kuaj xyuas qhov teeb meem tsis muaj kev cuam tshuam tsis muaj teeb meem).
Txog kev tshaj lij kev sim, xa mus rau cov roj av theem (piv txwv li, nas 1638).
III. Kev Ua Haujlwm Ua Haujlwm
1. Kev ntsuam xyuas siab
Cov txheej txheem hydraulic lub zog yuav tsum muaj ntau dua los yog sib npaug rau 0.1 mpa, thiab 0.2-0.5 mpa ntawm qhov nrawm.
Cov roj av tsis sib haum siab los yog cov twj paj nruag yuav tsum muaj teeb meem cov roj twj tso kua roj / lim.
2. Hais dab tsi
After mixing hydraulic oil and water, allow the oil to separate for<=5 minutes (standard for No. 8 hydraulic transmission oil).
IV. Kev Ntsuas Kev Ntsuas
Kev kuaj xyuas: Xa cov qauv roj tsis tu ncua rau kev tsom xam ntawm cov cim, nyem taw tes (ntau dua lossis sib npaug.
Roj Puifier kev kho mob: yog tias tsis huv yog kuaj pom, siv lub nqus roj nqus pa purifier tshem tawm cov dej noo thiab tsis huv.
