Kuv yuav ua li cas thiaj yuav tsum ua kom lub tshuab sib txuas tshuab tom qab nws tau ua tiav rau lub sijhawm txuas ntxiv?

I. Thaum Muaj Xwm Ceev Kaw Tshuaj
1. Kev tshuaj xyuas hluav taws xob
Tam sim ntawd disconect lub zog muab. Siv tus melohmeter mus xyuas lub cev muaj zog wawb wwb rwb thaiv tsev tsis kam (yuav tsum loj dua los yog sib npaug rau 1mω). Txheeb xyuas cov neeg tiv toj rau kev hlawv (yog tias thaj chaw tiv tauj tsawg dua 80%, hloov).
2. Mechanical Cheebtsam
Manually crank the machine to check the bearing rotational resistance (normally, it should be less than 5N·m). Measure the vibration value (>4.5mm / s, hloov cov kabmob). Ii. Kev Tu Khoom Txheej Txheem
1. Tuam thiab Screen Txij Nkawm
Disassemble the tool and inspect for wear (single-side wear >2 hli yuav tsum hloov). SKD-11 Cov cuab yeej SKD yuav tsum yog qhov chaw rov qab mus rau ib qho ntse ntse ntawm RA tsawg dua lossis sib npaug rau 0.8μm.
Clean the screen for blockage (pore blockage >30% yuav tsum hloov). Txheeb xyuas cov tshuaj ntsuam xyuas (SAG yuav tsum<3mm).
2. Lubrication system rov kho dua
Hloov cov kabmob roj (siv cov roj nli qib 2 lithium-}} raws li kev hloov pauv ntawm lub cav. Ntub cov ntxaiv bearings tshwj xeeb (txhua 200 teev).
III. Kev Ua Haujlwm Ua Haujlwm
1. Tsis muaj - kev thauj khoom khiav
Tom qab pib, saib xyuas tam sim no hloov pauv (yuav tsum nyob rau hauv ± 5% ntawm tus nqi ntsuas). Khiav rau 30 feeb thiab ntsuas cov kabmob sib kis kub nce (tsawg dua los yog sib npaug rau 40℃yog ib txwm).
2. Thauj Test
Maj mam nce tus nqi pub rau tus ntaus nqi thiab saib xyuas kev ua tau zoo (Tooj liab purity yuav tsum muaj ntau dua los yog sib npaug ntawm 98%). Yog hais tias kev txawv txav tshwm sim, kho tus damper nrawm (pom zoo ntau: 8-12 m / s).
