SB315 Kev Nyab Xeeb nres ua raws li "kev saib xyuas hierarchical" raws li cov sij hawm ua hauj lwm thiab kev siv zaus, nrog cov kev tu vaj tse tseem ceeb muab faib ua kev tshuaj xyuas txhua hnub, kev saib xyuas tsis tu ncua, thiab kev kho txhua xyoo.
1. Kev tshuaj xyuas txhua hnub (1 Sijhawm / Ua Haujlwm)
Xyuas hydraulic system siab (yuav tsum nyob rau hauv 16-21 MPa) thiab rau cov roj to ntawm lub tog raj kheej pob qij txha, hoses, thiab fittings.
Txheeb xyuas qhov xwm txheej ntawm kev nyab xeeb hloov pauv (tso txwv + hauv ob sab hauv hnav txwv) kom ntseeg tau tias lawv xa cov teeb liab ib txwm mus rau kev tswj hwm.
Tshawb xyuas lub brake disc nto rau cov roj stains, hlau khib nyiab, lossis khawb pom pom tseeb; ntxuav tam sim yog tias pom muaj kab mob.
Mloog lub suab nrov txawv txav thaum nres / tso tawm; daws teeb meem yog tias muaj jitter lossis squealing.
2. Kev tu tsis tu ncua (Tsov voj voog)
| Kev Kho Vaj Tse | Cov haujlwm tseem ceeb |
|---|---|
| 3 Lub Hlis lossis 500 Lub Sijhawm Ua Haujlwm | Xyuas hydraulic roj zoo (hloov yog tias nws tsis muaj xim, turbid, los yog muaj impurities). Ntxuav cov roj lim thiab cua tshuab pa ntawm qhov chaw nres tsheb hydraulic. Tshawb xyuas hose aging (hloov yog tawg los yog bulges tshwm). |
| 6 Lub Hlis lossis 1000 Lub Sijhawm Ua Haujlwm | Ntsuas kev sib txhuam hauv ob sab phlu thickness (hloov tam sim yog Tsawg dua los yog sib npaug li 5 hli). Tshawb xyuas kev ruaj ntseg ntawm lub tog raj kheej hydraulic (hloov cov ntsaws ruaj ruaj kom tsis txhob xau). Txheeb xyuas disc parallelism (kho yog qhov sib txawv tshaj 0.15 hli). |
| 12 Lub Hlis lossis 2000 Cov Sijhawm Ua Haujlwm | Overhaul hydraulic thooj voos kheej kheej: Disassemble, huv si piston rods, thiab hloov aging seals. Resurface tus nres disc yog hnav qhov tob tshaj 2 hli los yog muaj qhov sib sib zog nqus grooves. Calibrate kev ruaj ntseg keyboards kom paub meej tias cov teeb liab tshwm sim. |
| 2 Xyoo lossis 4000 Lub Sijhawm Ua Haujlwm | Tshawb xyuas disc caij nplooj ntoos hlav elasticity (hloov yog tias qaug zog deformation lossis poob ntawm kev quab yuam). Ua ib daim ntawv qhia tag nrho -kev ntsuas qhov ntsuas siab (siab poob yuav tsum Tsawg dua lossis sib npaug li 0.5 MPa hauv 10 feeb). Hloov tag nrho cov hydraulic hoses (txawm tias tsis pom kev puas tsuaj, vim kev laus yuav ua rau muaj kev pheej hmoo zais). |
3. Kev kho ib puag ncig tshwj xeeb
Hauv plua plav, av noo, lossis siab - ib puag ncig ntsev (piv txwv li, chaw nres nkoj, mines), ua kom luv txhua lub voj voog txij nkawm los ntawm 30% (piv txwv li, kev saib xyuas 6 lub hlis dhau los ua 4.2 lub hlis).
Rau kev ua haujlwm tas mus li (24/7) lossis siab- siv zaus (Ntau dua lossis sib npaug rau 1000 cycles / hli), txo 3 lub hlis txij nkawm mus rau 2 lub hlis thiab kev saib xyuas 6 hli mus rau 4 lub hlis.
4. Kev ceev faj txog kev tu
Txhua qhov kev saib xyuas yuav tsum tau ua tom qab txiav tawm lub zog thiab txo qis hydraulic system siab (ua raws li cov txheej txheem LOTO).
Siv cov roj hydraulic nkaus xwb (ISO VG 32/46) thiab cov khoom qub qub (tshwj xeeb tshaj yog cov hlua khi, cov ntsaws ruaj ruaj, thiab cov dej ntws) kom tsis txhob muaj kev puas tsuaj.
Sau cov ntaub ntawv txij nkawm (hnub tim, qhov chaw hloov, cov ntaub ntawv xeem) txhawm rau taug qab tus nres qhov kev pabcuam.
Koj puas xav kom kuv sau aprintable daim ntawv teev cov ntaub ntawvrau SB315, suav nrog cov khoom tshuaj ntsuam xyuas, kev ceeb toom lub voj voog, thiab cov ntawv xeem cov ntaub ntawv nkag, txhawm rau pab txhawb kev taug qab tus qauv?
