Nce corrosion kuj ntawm piston pas nrig nto

Yuav ua li cas los txhim kho corrosion kuj ntawm piston pas nrig nto?

Lub piston pas nrig yog ib qho txuas uas siv dav hauv cov khoom siv tshuab feem ntau tam sim no. Txawm li cas los xij, vim qhov hnyav ib puag ncig ntawm qee qhov kev siv tshuab, muaj cov kev xav tau siab heev rau kev tiv thaiv corrosion ntawm piston pas nrig. Yog li cas peb yuav tsum txhim kho qhov kev tiv thaiv corrosion ntawm piston pas nrig nto?
Cov txheej txheem ntawm kev txhim kho corrosion kuj ntawm piston pas nrig nto:
1. Rolling ua:
Los ntawm kev sib sau ua ke, txheej txheej ntawm kev ua haujlwm txias txias yog tsim rau ntawm qhov chaw dov, uas txo cov elastic thiab yas deformation ntawm kev sib cuag ntawm tus khub sib tsoo, thiab tuaj yeem ncua lub tiam los yog nthuav tawm ntawm qaug zog tawg, yog li txhim kho qhov chaw corrosion. tsis kam.
2. Chrome plating:
Lub piston pas nrig yog chrome-plated kom muaj ib qho nyuaj, du, corrosion-resistant nto. Yog li ntawd, yog tias koj xav txhim kho corrosion kuj ntawm piston pas nrig nto, koj yuav tsum mus los ntawm chrome plating. Tom qab chrome plating, lub hardness ntawm txheej ntawm lub piston pas nrig yuav siab li HV1100, thiab txheej yog du, uniform nyob rau hauv thickness, thiab muaj zog nyob rau hauv dispersion, thiaj li hais tias nws yuav ua tau zoo heev nyob rau hauv tej yam.
3. Kev Kho Mob:
quenching thiab tempering yog quenching thiab tempering kho ntawm tus pas nrig piston. Tom qab quenching thiab tempering kev kho mob, kev ua hauj lwm lub zog ntawm cov khoom yuav ua tau zoo dua qub, uas yuav pab kom kaw lub micro tawg ntawm qhov chaw, hinders lub expansion ntawm yaig, thiab yog li txhim kho cov nto corrosion kuj. Txawm li cas los xij, tsis yog txhua tus pas nrig piston yuav tsum tau quenched thiab tempered, yog li kev kho quenching thiab tempering yuav tsum raug txiav txim raws li qhov xwm txheej thiab cov khoom siv.
Cov ntsiab lus qhia saum toj no yog cov txheej txheem los txhim kho corrosion kuj ntawm piston pas nrig nto. Qhov zoo dua qhov corrosion kuj ntawm piston pas nrig nto, qhov yooj yim dua nws yog los tiv thaiv lub piston pas nrig los ntawm corroded, kom lub neej ntev kev pab cuam yuav tau.
