Puas yog lub pas hlau stainless piston pas nrig yuav tsum tau plated
Jul 15, 2019
Nyob rau hauv ib txwm muaj xwm txheej, ntau cov khoom siv tshuab thiab cov txheej txheem khoom siv yuav luag tsis muaj txoj hauv kev tawm ntawm lub pas nrig piston. Vim tias piston pas nrig yog cov koom txuas sib txuas, nws tuaj yeem ua haujlwm sib kis thiab kev txhawb nqa nyob rau hauv ntau hom kev sib txawv cov tshuab nrog cov kab tawm rov qab. Txawm li cas los xij, kev tsim cov khoom siv piston pas nrig yuav tsum muaj cov txheej txheem xws li sib tsoo, electroplating, polishing, thiab lwm yam ua ntej nws tuaj yeem tsim tawm. Yog li puas stainless hlau piston pas nrig yuav tsum tau plated? Qhov tseeb, cov hlau stainless piston pas nrig yuav tsum tau plated. Vim tias qhov thiaj li hu ua electroplating, nws hais txog txheej txheem ntawm cov plating tuab chrome plating nyob rau saum npoo ntawm steel substrate. Tom qab plated, stainless hlau piston pas nrig tuaj yeem txhim kho lub hardness, hnav tsis kam, kub tsis kam thiab tiv taus corrosion ntawm ib feem los ntawm kev siv cov yam ntxwv ntawm chromium.
Stainless hlau piston pas nrig feem ntau muaj cov tuab li ntawm 10-30 μm lossis ntau dua. Ntxiv mus, nws plating feem ntau yuav tsum muaj tsawg kawg 3 zaug ntawm chrome plating. Thaum ua cov chrome plating ib zaug, lub thickness yuav tsum tau tswj ntawm 0.010 thiab 0.015 hli. Ntxiv mus, thawj thawj zaug, tom qab chrome ib daim plating, lub tog raj kheej xav tau hauv av thiab tom qab ntawd chrome-plated rau qhov yuav tsum tau tuab kom ncav cuag qhov loj me thiab ces polished.
daim ntawv:
Lub pas hlau stainless piston pas nrig yuav tsum tau polished ua ntej plating. Tom qab ntawd, qhov ntev ntawm lub qhov plated thiab qhov saum npoo ntawm lub tshuab ua tiav tas yuav tsum raug kuaj xyuas, thiab tom qab ntawd lub sijhawm plating yuav tsum tau ntsuas kom raug raws li cov tuab ntawm txheej. Ntxiv mus, nyob rau hauv cov ntaub ntawv ntawm rov chrome plating ntawm lub pas hlau stainless piston pas nrig, nws yog qhov tsim nyog yuav tsum tau them sai sai rau cov tuab nruab nrab ntawm piston pas nrig plating txheej thaum lub tuab tuab yog 0.010 txog 0.015 hli. Qhov no ua tau zoo tuaj yeem txhim kho qhov kawg los tiv thaiv kev tiv thaiv qib ntawm tus pas nrig piston.
