Qarqardaha dhuunka waxaa la sameyn karaa garsoorka dadkana wadajirka, ku yidhi lacagta pistoonka ka mid ah carruurta. Halkan, macluuma haddii ugu yaal sida markaas oo qarqardaha ah, si ay lacagta filmka carruurtanka uga tagto, si aysata dhacdo carruurta , droplets carruurta lacagta , iyo dhicdho caafimaadka bearing seizure . Waxaad ku jiro kartaa lacag dheer qarqardhka ah ee xaalad ah, laakiin tacnooyinka fududinta ah—sida HTL nano-finishing abrasive kits —waxaa lagu sameyn karo qarqardaha dhuunka ah oo ka mid ah suuraha OEM, si aad uga tagto halkaas carruurka.
Journal scratches waxay ku jirtaan ridgaha mikriska ah oo ka toreyn oil film, ku yaal kartaa crankshaft iyo bearing ku samayn doonin metal-metal contact. Waxay ku jirtaan chain reaction:
Xaalada carruurta : Scratches wuxuu ku yimid debris, clogging oil passages iyo ka soo galitaan efficiency lubrikaashada.
Friction xiriir ah : Surfaaceynta badan waa la mid ah caliis, ku socda bearing alloy wear.
Bearing seizure : Scoring badan waxay ku weldan bearing taajurta, locking crankshaft.
Caasimaha Dhexeeya Journal Damage:
Oil contaminated (metal particles, dirt).
Assembly carruur ah (scratches tool ama debris).
Ku qarsoon ah inta badan oo dhexdeeda coolanta ama siinada ah ku jiray.
Salaadda ayaa waxaa lagu sameyn karaa salaadda sandpaper ama grinding wheels oo aan ugu yaraan in laga heliyo. HTL's kits ayaa iska soo baxaan diamond-impregnated abrasives iyo micro-polishing compounds ku saabsan surface lacagta sub-micron (Ra ≤ 0.1 µm). Fursadaha macluuma:
Processee ee aan u baahan kartaa : Waxyaabihii aan uga taggal kartaa dimashuunka journal.
Abrasives ee ay u adeegsanaan kartaa : Waxaad ka samayn doontaa girta grit size (200–3,000) haddii aad u baahanaysid deep scratches ama lacagta mirror final.
Naqshadeynta la qaadi karo : Ka qeyb qofka ama ugu badan, ku yaal in lagu sameyn doono.
1. Fikir iyo Dhig
Tiri shaftii iyo degrease journallaha waxa uu dhammaadayaan.
Istamaar micrometer ee diyaamitarka journal iyo out-of-roundness (tireer: ≤0.02 mm).
2. Xiriir Girtiga Abrasive
Lacagta ah oo ku jiro (>0.05 mm): Roga 200-grit abrasive strips.
Maxaydii fine polishing: Tixi 1,500–3,000 grit.
3. Farsha HTL's Tool
Gooji girtiga abrasive kaas oo ay jiraan journal iyo sidoo kale kuhu yimid HTL's oscillating tool.
Ku jira abaaraha 300–500 RPM, ku yidhiisa horaynta ah oo u diriraa waxbarashada crosshatch.
Tikiso dadkii kasta 2–3 daqiiqadda kaliya macluumaalka surface profilometer.
4. Warqad Final
Roga nano-particle polishing ku dar roobka microfiber.
Hand-polish joournal ku saarida horynta ah madeebo cirqa ah.
5. Sameysi iyo Iska Fidin
Joornals ku dhac thoroughly kaasoo uga tag abrasive residue.
Reinstall bearings iyo u baahnaa dhexdeedka (target: 40–60 PSI marka idle).
La ciyaan kartaa measurement : Polishing joornals aan la xiriira dimensions risks oversizing.
Over-polishing : Qeybta badan ah ee ku sameyn kartaa kaalmada ugu yar.
Tirtirinta carruurtida ayaa si toos ah ii dooninayaa. : Carruurka aasaas ah ku saabsanaya dalagtooyinka—waalidi macluumaad airka ka dib.
Ku sameyn qeybta carruur : Nasiibka crosshatch wuxuu ku sameyn qeybta carruur la xiriira doorasho.
Ku sameyn dhulka caano : Dhalinyarooda oo kaliya wuxuu ku sameyn dhulka caano ee ku jira in lagu talagalayso heat.
Waxbarasho ah : Waxaa la sameyn 60–80% oo dhan oo ka dib crankshaft replacement.
Filtirinta karo : Ilaallo 10-mikron ee ku jiro marka ah u diriyo carruur.
Talowga Dhibaato : Fogaanta joogtooyinka karo oo ka mid ah dhibaatooyinka badbaadada.
Dheer ugaab : Markii aad ugu sameeyo, gal abaaraha aan waxaa la sameeyo si waa inaad ugaabo barashada.
Marka hore oo ku jirto joogtooyinka crankska maahan ugu muuqataan. Waxa laga heli karo qodobadda HTL, waxaana ku jirto salka adeegga ah oo ku jira carruur caddeed, oo ku saabsan bal eego xogta abaaraha iyo ku carar kartaa doorashada lacagga.
Caaw: Ma ogolaayo markii adeegga ah ay ku jirto joogtooyinka carruur?
Wiil: Haa, laakiin carruur caddeed ee ku jirto macluumaad ay ku yimaado gurigaanka.
Caaw: Maxay martaba adeegga ah ay ku jirto joogtooyin?
A: Haddii aad ugu baahantahay 3 martiisaan, markii fursadaha ayaa mid ah ee OEM.
Q: Kuna fiiri kartaa wax ka qarsoonka carraanka?
A: La'a—tirooyin ee ku jiray waa in lagu sameyn karaa (≤0.001 mm).
