Yuav ua li cas kho lub tog raj kheej, piston thiab piston rods uas hnav los yog grooved?

1) Thaum kho, sab hauv thiab sab nraud diameters thiab roundness yuav tsum raug ntsuas kom raug. Yog hais tias lub puab tsaig sab hauv ntawm lub tog raj kheej yog hnyav hnyav, nws tuaj yeem kho tau los ntawm kev sib tsoo nrog kev sib tsoo mandrel los yog honing ntawm lub tshuab tho txawv; Yog tias lub voj voog sab nrauv ntawm lub piston hnav, nws tuaj yeem kho tau los ntawm electroplating. Yog tias hnav hnyav, nws yuav tsum tau hloov. Yog hais tias lub piston pas nrig yog hnav, txhuam plating tuaj yeem ua ntej, tom qab ntawd sib tsoo, thiab thaum kawg qhov sib txuam ntawm tus pas nrig piston thiab lub tes tsho qhia tuaj yeem hloov kho. Lub sijhawm no, lub tes tsho qhia tuaj yeem tsim nyog rov qab los yog lub tes tsho qhia tuaj yeem tig rov qab. Thaum ua cov kev kho saum toj no, nco ntsoov hloov ntau yam roj hmab foob hauv lub sijhawm.
2) Thaum lub piston pas nrig yog grooved lossis lwm yam puas lawm, lub tsheb fais fab tuaj yeem kho los ntawm txhuam plating lossis vuam kho. Thaum kho cov vuam, ua ntej stabilize lub piston pas nrig, ntxuav cov roj nrog dej acid, thiab tom qab ntawd khoov ib daim phaj tooj liab (2 hli tuab) rau hauv cov duab xav tau. Qhov loj thiab cov duab ntawm vuam qhib yuav tsum tau txiav raws li qhov xav tau tiag tiag. Thaum kawg, siv cov ntsia hlau los tuav nws ntawm tus pas nrig piston, thiab qhov chaw nyob ib sab yuav tsum tau thaiv cov khoom siv insulating ua ntej kev kho vuam tuaj yeem pib. Nws yuav tsum yog av tom qab vuam.
3) Txhuam plating txheej txheem kho.
