Kev ua haujlwm ntawm hydraulic lim:
Kev ua haujlwm ntawm hydraulic lim yog lim ntau yam impurities hauv hydraulic system. Nws cov peev txheej feem ntau suav nrog cov neeg kho tshuab impurities uas tseem nyob hauv hydraulic system tom qab ntxuav, xws li dej xeb, casting xuab zeb, vuam slag, hlau filings, coatings, xim ntawm daim tawv nqaij thiab paj rwb scraps, thiab lwm yam., impurities nkag mus rau hauv hydraulic system los ntawm sab nraud, xws li plua plav nkag los ntawm qhov chaw nres nkoj refueling thiab plua plav plua plav, thiab lwm yam .; impurities generated thaum lub sij hawm ua hauj lwm, xws li fragments tsim los ntawm hydraulic kev txiav txim ntawm cov ntsaws ruaj ruaj, hlau hmoov generated los ntawm cov txheeb ze ntawm kev txav, colloid, asphaltene, carbon slag, thiab lwm yam generated los ntawm oxidation thiab deterioration ntawm roj.
Nta ntawm hydraulic lim:
1. Nws muab faib ua ntu siab, ntu nruab nrab-siab, ntu roj rov qab thiab ntu roj nqus.
2. Nws muab faib ua theem siab, nruab nrab thiab qis precision. 2-5um yog siab precision, 10-15um yog nruab nrab precision, thiab 15-25um yog tsawg precision.
3. Kom compress cov lim tiav qhov ntev thiab ua kom pom qhov chaw, cov txheej lim feem ntau yog folded rau hauv cov duab corrugated, thiab pleating qhov siab ntawm hydraulic lim caij feem ntau qis dua 20 hli.
4. Lub siab sib txawv ntawm hydraulic lim caij feem ntau yog 0.35-0.4MPa, tab sis qee qhov tshwj xeeb lim cov ntsiab lus yuav tsum tau ua kom muaj kev sib txawv siab, nrog rau qhov siab tshaj plaws ntawm 32MPa lossis txawm tias 42MPa sib npaug rau qhov system siab.
5. Qhov kub siab tshaj plaws, qee qhov xav tau txog li 135 ℃.
Yuav tsum tau rau hydraulic lim ntsiab:
1. Cov kev xav tau muaj zog, kev tsim khoom ruaj khov, siab sib txawv, kev teeb tsa sab nraud quab yuam, thiab qhov sib txawv ntawm qhov sib txawv load.
2. Cov kev xav tau rau cov roj ntws zoo thiab cov yam ntxwv ua haujlwm zoo.
3. Resistant rau tej qhov kub thiab txias thiab sib xws nrog cov nruab nrab ua hauj lwm.
4. Cov txheej lim fibers tsis tuaj yeem raug tshem tawm lossis poob.
5. Nqa av ntau dua.
6. Ib txwm siv nyob rau hauv qhov siab thiab qhov chaw txias.
7. qaug zog tsis kam, qaug zog lub zog nyob rau hauv alternating ntws.
8. Kev huv huv ntawm cov khoom lim nws tus kheej yuav tsum ua raws li tus qauv.
Hydraulic lim hloov lub sij hawm:
Hydraulic excavators feem ntau yuav tsum tau hloov cov roj hydraulic tom qab 2000 teev ntawm kev ua haujlwm, txwv tsis pub lub kaw lus yuav muaj kuab paug thiab ua rau lub cev tsis ua haujlwm. Raws li kev txheeb cais, kwv yees li 90% ntawm hydraulic system tsis ua haujlwm yog tshwm sim los ntawm cov pa phem.
Ntxiv rau kev tshuaj xyuas cov xim, viscosity, thiab tsw ntawm cov roj, cov roj siab thiab cov av noo yuav tsum tau kuaj. Yog tias ua haujlwm nyob rau hauv ib puag ncig nrog qhov siab siab thiab qis qis, koj yuav tsum tau ua tib zoo saib xyuas cov ntsiab lus carbon, colloids (olefins) thiab sulfides hauv cov roj cav, nrog rau cov impurities, paraffin thiab dej cov ntsiab lus hauv diesel.
Hauv qhov tshwj xeeb, yog tias lub tshuab siv cov roj av qis (cov ntsiab lus ntawm cov sulfur hauv diesel yog 0.5﹪～1.0﹪), lub tshuab lim thiab tshuab lim yuav tsum tau hloov txhua 150 teev; Yog tias cov ntsiab lus ntawm cov sulfur siab tshaj 1.0﹪, lub tshuab lim dej thiab tshuab lim yuav tsum tau hloov txhua 60 teev. Thaum siv cov cuab yeej xws li crushers thiab vibrating rammers uas muaj cov load loj ntawm lub hydraulic system, lub sij hawm hloov ntawm hydraulic rov qab lim, tsav lim thiab lub tshuab ua pa lim yog txhua txhua 100 teev.
