Hnav tsis kam: Cov hnav tsis kam ntawm cov tes tsho tooj liab tseem tseem tau zoo, thiab cov khoom siv ntawm cov khoom sib txawv nyias muaj nyias tus yam ntxwv. Lub koom haum sab hauv ntawm qhov chaw ntawm tooj liab bushing yog tus nruj, thiab tsis muaj qhov tshwm sim dhau ntawm xoob. Nws tsis muaj qhov hws thiab tsuab, li ntawd cov tooj liab ua kom pom kev ci ntsa iab tuaj ntawm lub ntsej muag, thiab nws cov xim kuj tshwj xeeb heev. Thiab qhov tseem ceeb tshaj plaws yog tias nws cov hardness yog siab.
Kev xeb: Ib qho ntxiv ntawm tooj liab bushings yog xeb tsis kam thiab ua haujlwm zoo corrosion. Nws yog tsuas yog siv nyob rau hauv qhov chaw cua thiab dej ntshiab, vim hais tias ib puag ncig zoo kuj zoo. Hauv kev siv cov neeg siv tooj liab, nws ib txwm tsis yooj yim mus txeeb. Cov tshuaj tiv thaiv corrosion ntawm tooj liab bushings yog qhov tseem ceeb nyob rau hauv qee cov tshuaj lom neeg, xws li: dilute sulfuric acid, hydrochloric acid thiab fatty acids, thiab lwm yam, yog li ntawd qhov kev kho tsis kam ntawm tooj tooj bushings zoo heev, vim li cas nws tsis tshwm sim foob feem ntau yog vim nws tus kheej cov yam ntxwv thiab nws qhov kev ua tau zoo kuj zoo. Txawm hais tias tsis muaj roj nplua nyeem thiab dej zoo lubricant, nws tseem tuaj yeem ua haujlwm ib txwm, thiab nws cov zawv zawg thiab nws tus kheej lubricating kev ua tau zoo tseem tuaj yeem tswj hwm. Cov.
Hlaws ua hauj: Lub siab tsis kam ntawm lub tes tsho tooj liab kuj tseem zoo. Nws qhov siab saum npoo yog qhov loj heev, thiab nws tuaj yeem tiv taus sab sab ntawm cov kabmob zoo. Lub tes tsho tooj liab kuj tseem tuaj yeem ua haujlwm hauv qab lub siab thauj khoom. Nws yog tsim rau kev ua haujlwm qis-nrawm-chaw thau khoom ntau lub sijhawm.
