Lub twj tso kua mis plunger yog cov cuab yeej tseem ceeb hauv kev tsim roj thiab roj, dav siv hauv kev tawg, cementing thiab dej txhaj tshuaj. Raws li lub ntsiab lus tseem ceeb ntawm lub twj tso kua mis plunger, lub pas nrig plunger yog qhov yooj yim rau kev sib txhuam kev puas tsuaj los ntawm kev sib zog ua haujlwm siab thiab yaig ntawm nruab nrab corrosion thiab nyuaj hais thaum ua haujlwm, thiab nws lub neej kev pab tsuas yog 15 mus rau 35 hnub.
Cov roj av loj yuav muaj ntau txhiab lub twj tso kua dej, txhua txhua xyoo yuav tsim ntau cov khib nyiab plunger rods. Txhawm rau kho cov txiaj ntsig qub pov tseg thiab pab cov lag luam ua tiav lub hom phiaj ntawm kev txo cov nqi thiab nce kev ua tau zoo, Xi 'an Guosheng laser tau tsim thiab siv remanufacturing thiab nto zog technology rau ntau xyoo. Nws raws li high-speed laser cladding technology yog nqa tawm rau cov khib nyiab plunger rods.
Cov txheej txheem kev kho deg ntawm lub plunger pas nrig suav nrog electroplating, tshuaj tsuag vuam thiab lwm yam. Electroplating tau maj mam tshem tawm vim muaj kuab paug ib puag ncig thiab txheej txheej tsis zoo. Txawm hais tias cov tshuaj tsuag welding Ni60 thev naus laus zis tuaj yeem tau txais cov khoom tsim nyog ntawm cov txheej txheem, vim muaj cov cua kub loj, nws tsis tsuas yog muaj kev cuam tshuam rau cov khoom siv ntawm matrix tab sis kuj muaj qhov deformation loj. Tom qab machining, lub thickness uniformity ntawm lub zoo cladding txheej yog tsis zoo, uas ua rau nws yooj yim rau deform lub sib koom tes ntawm lub plunger pas nrig thiab ua rau seem ntawm lub workpiece. Yog li ntawd, cov nplaim hluav taws xob vuam tshuab tsis tsim nyog rau kev rov ua dua ntawm lub plunger pas nrig, thiab lub plunger pas nrig nto ntxiv dag zog nrog cov thev naus laus zis no tsis tsim nyog rau kev rov ua dua tshiab ntawm qhov khoob.
Sib txawv ntawm cov tsoos laser cladding, high-speed laser cladding los ntawm kev hloov cov txheej txheem ntawm laser thiab hmoov, yaj los yog ib nrab yaj cov hmoov ntawm lub molten pas dej ua ke, yaj los yog semi-melt kua ntws mus rau hauv lub molten pas dej ua ke, tsim ib tug metallurgical bonding nto. txheej, nws cladding efficiency thiab nto zoo tuaj yeem txhim kho. Piv nrog cov tshuaj tsuag vuam thiab cov tsoos laser cladding, nws muaj qhov zoo ntawm kev ua haujlwm siab, tsis tshua muaj cua sov input, tsawg dilution tus nqi, nyias txheej, tiaj tus thiab me me ntawm kev ua raws li cov txheej txheem.
High-speed laser cladding muaj cuab kev zoo nyob rau hauv cov khoom zoo thiab cuam tshuam rau lub matrix. Nws tuaj yeem siv tsis tau tsuas yog rau saum npoo ntxiv dag zog tab sis kuj rau plunger pas nrig remanufacturing.
Raws li qhov sib txawv ntawm kev ua haujlwm thiab kev puas tsuaj, lub plunger pas nrig tau muab faib ua A, B thiab C peb thaj chaw raws li sab nrauv.
1. Thaj Chaw A yog txoj haujlwm txuas ntawm lub plunger pas nrig thiab lub taub hau tappet. Vim txo qhov loj me thiab hloov sai sai, nws yog qhov chaw tsis muaj zog ntawm tag nrho cov khoom ua haujlwm, uas ua rau tawg thiab deformation, thiab muaj me ntsis pitting thiab xeb.
2, Cheeb Tsam B yog lub ntsej muag ua haujlwm tseem ceeb ntawm lub plunger pas nrig, tab sis kuj muaj qhov tsis zoo ntawm qhov chaw, muaj qhov pom tseeb khawb thiab pitting pits ntawm qhov chaw, yog qhov tseem ceeb ntawm kev kub ceev laser cladding remanufacturing.
3. Cheeb Tsam C yog lub ntsej muag kawg ntawm kev sib cuag ncaj qha ntawm lub plunger pas nrig thiab cov kua, thiab muaj qhov pom tseeb corrosion, tshwj xeeb tshaj yog corrosion loj ntawm qhov chaw nruab nrab (los yog sediment erosion). Rau qhov sib sib zog nqus corrosion los yog yaig qhov (ntau tshaj 2 hli), phau ntawv argon arc vuam yog siv los kho qhov loj thiab tom qab ntawd kev kho mob siab ceev laser cladding.
Remanufacturing los yog nto ntxiv dag zog rau plunger rods nrog high-ceev laser cladding tshuab muaj cov nram qab no nta
1. Tsawg cua sov input, me me deformation, high efficiency, uniform thickness ntawm cladding txheej, me me kev puas tsuaj rau lub neej matrix.
2. Lub siab ceev laser cladding yog siv los ntxiv dag zog rau saum npoo ntawm lub plunger pas nrig, uas tuaj yeem rov ua dua tom qab siv, txuag cov khoom siv raw khoom thiab ib feem ntawm kev ua haujlwm ntawm lub cev pas nrig.
3. Lub dilution tus nqi ntawm high-ceev laser cladding tsis tshaj 3%, thiab cov thinner cladding txheej thickness (0.2mm) tuaj yeem ua tau raws li qhov yuav tsum tau ua thiab txo cov hmoov av pov tseg.
4. Lub nto roughness ntawm high-speed laser cladding yog tsawg li Ra12.8m, uas tuaj yeem ua tiav ncaj qha los ntawm kev sib tsoo tshuab.
5. Lub hardness ntawm cov hlau matrix composite hmoov cladding txheej yog ntau dua HRC55, hnav tsis kam thiab corrosion kuj ntawm cov txheej cladding tsis qis dua li cov tshuaj tsuag vuam Ni60, lub thickness ntawm cov cladding txheej yog uniform, thiab thickness sib txawv. ntawm txheej cladding yog tsawg dua 5 microns tom qab machining, thiab kev pab cuam lub neej ntawm lub plunger pas nrig yog zoo heev.
6. Nrog high-speed laser cladding technology raws li cov tub ntxhais, tag nrho cov plunger pas nrig remanufacturing txheej txheem yog ntsuab, ib puag ncig tiv thaiv thiab tsis muaj kuab paug.
