Cov txheej txheem kev cai qub yog qhov zoo tshaj plaws hauv kev tsim, txawm tias nyob rau hauv daim ntawv ntawm cov qauv lossis cov khoom xaiv yog kev tshawb fawb thiab qib siab heev, tsim nyog rau cov kev xav tau ntawm lub twj tso kua mis. Los ntawm qhov xwm txheej tiag tiag ntawm cov khoom qub qub, thaum muaj cov hlau oxide ntau ntau hauv cov kua qaub, lub nplhaib txav thiab lub nplhaib zoo li qub ntawm lub ntsiab foob ntawm lub tshuab foob yuav hnav sai sai, ua rau tsis ua haujlwm ntawm lub tshuab foob, thiab lub hauv paus ua rau camshaft puas yog qhov hnav ntawm lub twj tso kua mis txhaj tshuaj lub cev.
Rau qhov camshaft tawg peb tuaj yeem siv cov hauv qab no los daws:
1. Cov npauj npaim valve tuaj yeem siv los txuas lub twj tso kua mis lub cev nrog hluav taws xob vuam thiab brazing. Lub thickness thiab cheeb tsam piv hnav ntawm pawg kho yog loj. Tom qab welding, qhov vuam qhov tuaj yeem polished thiab flattened los ntawm kev ua ntaub ntawv thiab sib tsoo kom rov qab zoo li qub.
2.Cov txheej txheem ntawm cov hlau nplaum kho. Txhawm rau kho lub twj tso kua mis lub cev ntawm lub twj tso kua mis, cov kua nplaum npaj tau siv rau hauv qhov chaw hnav ntawm lub qhov rooj valve. Lub thickness thiab cheeb tsam ntawm cov hlau nplaum txheej yuav tsum yog me ntsis ntau dua li qhov hnav. Tom qab solidification, lub cheeb tsam coated nrog hlau nplaum yog polished, thiab ces lub installation thiab debugging yuav ua tau.
