Processus de nettoyage de shot blasting pour seau chargeur
Seau chargeur yi dañu yaatu, jëmm ju jaxasoo, am doole ju kawe Seen surface dafa muur ak limu slag soudure bu bari, scale oxide, rouille, ak barabi dagg yi war nañu leen dëgëral benn yoon. Ni ñuy raxasee shot blasting mooy lii ci topp:
1. Liggéeyu waajal: Tanneef jumtukaay ak faj
1.1 Tann masin biy jëfandikoo
Tannal masin bu yaatu -tonnage double -xeetu masinu tiire (ngir defar ci lots, mën nañu tann masinu tiire hoist bu jaar -):
Sargal biy yéeg dafa wara ëpp wala tollu ci 1,2 yoon diisaayu seau bi (ngir seau chargeur bu 5 ton, benn diisaay bi mooy 1-2 ton, tànnal seau bu 5 ton). Dayo chambre de explosion bi dafa wara ëpp dayo bi gëna mag ci seau bi ci 15% wala lu ëpp ngir mëna am diggante 0.75-1.5 meetar diggante pièce de travail bi ak masin de explosion bi, moytu mbëkkante wala distance bu doywul ngir sànni.
Hoist bi dafa wara mëna wëréelu boppam 360 degre, ba noppi am aparey yuy jël lu ëpp wala lu tollu ci 6 shot ngir muur bërëb bi ci biir, tombi soudure yi, catu dagg yi ak yeneen barab yu nëbbu yi ci seau bi.
1.2 Pre-traitement pièce de travail (points de contrôle de qualité clés)
Defect pre-grinding: Grinding manuel ngir dindi > 1mm spurs soudure ak splashes soudure - protrusions yu mag dina waral tir bi rebond, mu jur surface pitting bu jaxasoo te mënu ñu ko dindi ci saasi ci tir blasting.
Tëj pax mi: Jëfandikool bouchon kawsu ngir tëj pax mi ci arbre pin bi, pax mi ci file bi, ak pax yi ci processing bi ngir moytu tiire bi duggu wala indi jafe-jafe ci montage bi ci topp.
Centre finding: Markeel position centre bu seau bi, fexeel balance bi ngay yéeg ngir moytu yëngu wala mbëkkante ci diggu tiire bi.
2. Core tiire jëfandikoo jëfandikoo ak jekkal parametre
1.1 Liggéey buñ miin (mënu ñu ko soppi)
Tambali -up: Tambali sistemu dindi pënd → Tambali ascenseur bi → Tambali separatër bi → Tambali masinu mbëkk yi benn-benn → Tambali wëréelu boppam - → Ubbi vanne biy joxe pellet
Liggéeyukaay bi: Hoist bi dafay yóbbu seau bi ci biir néegu tiire bi, mu wéy di wëreelu ak di sànni
Taxawal: Tëj vanne biy joxe pelet yi → Taxawal masin yiy jël pellet yi → Tàmbale bi dafay wéy di wëréelu ci diiru benn simili (ngir dindi pellet yi des) → Taxawal ascenseur bi/seperatër bi → Taxawal sistemu pënd bi
2. Reglage bu jaar yoon ci parametru prosedur bi (ñu méngale ko ak seau chargeur asiye yu am doole bu kawe)
Tanneef tiire: S330 alloy pellets asiye (diametre 0.8-1.2mm), ekilibre efficacité de nettoyage ak coating ñaq, tere jëfandikoo pellets fil asiye dagg (mën na waral surface ñaq bu ëpp)
Gaawaayu wëréelu masin buy jël tiire: 2500-2800rpm
Gaawaayu wëlbatiku boppam: 3-5r/min, ngir mëna am njeexital yu wuute ci bépp surface, te barab yu silmaxa yi mën nañu noppalu ak yamale angle suspension bi ci diiru liggéeyu tiire bi
Duru jëfandikoo: 5-8 simili, ngir seau yu màgget yu xoosu bu baax dem ba 10 simili, ngir seau yu bees yuñ soudé 5 simili doyna
Dindi pënd pression négatif: -15 ~ -20Pa, ngir moytu pënd tuuru ak fexe ba effet tàqale
3. Post- liggéey ak nangu kalite
1. Post- doxalinu jëfandikoo
Residu pellet raxas: Jëfandikool 0.6-0.8MPa air comprimé ngir fuur bërëb bi ci biir, souder tombi ñaw yi, ak barab yu nëbbu yi ci seau bi ngir dindi pellet yi ci biir;
Re-liggéey ci soudure yiñ raxasul ak barab yu nëbbu yi:定点 re-blasting ngir soudure yiñ raxasul ak barab yu nëbbu yi;
Saytu kaw gi: Xool bu baax ndax amul benn residu tiire balaa nga koy toxal ci liggéeyum coating bi.
2. Njàngat yiñ tëral ngir nangu kalite
Set: Yegg ci grade Sa2.5 (ci wetu-grade bu weex) - amul benn scale oxide buñuy gis, espores de soudure, wala rouille ci kaw suuf si, di wane melo metalik bu maase;
Xoos: Xoos surface bi ñuy saytu ci Ra20-30μm, ngir fexe ba couche bi ci topp yegg ci ISO 1 grade;
Amul ay pellet yuñ samp: Amul ay pellet yu des ci pax yi ak bërëb yi, te du indi jafe-jafe ci dajale bi ci topp.
