Cov hom kev hnav nyob rau hauv precision qhov chaw ua cov nroj tsuag feem ntau muaj xws li khiav hnav, tawv tawv hnav, nto qaug zog hnav, hnav zoo li kub, theem hloov hnav thiab hydrodynamic hnav.
Khiav-nyob rau hauv hnav yog hnav ntawm machinery nyob rau hauv ib txwm load, ceev thiab lubrication tej yam kev mob, hom hnav no feem ntau qeeb los tsim, lub sij hawm luv luv ntawm kev ua tau zoo tsis tseem ceeb.
Cov khoom siv tawv tawv yog vim cov khoom lawv tus kheej poob cov khoom abrasive los yog los ntawm lub ntiaj teb sab nraud mus rau hauv lub tshuab cuab yeej nyuaj, sib xyaw rau hauv qhov chaw ua haujlwm, raug rau cov neeg kho tshuab txiav lossis sib tsoo, ua rau puas tsuaj rau cov khoom, uas muaj kev cuam tshuam loj dua rau cov khoom siv. zoo ntawm machining.
Precision qhov chaw ua cov nroj tsuag deg qaug zog hnav yog machinery nyob rau hauv qhov kev txiav txim ntawm alternating load, tsim ib tug me me tawg los yog chav kawm ntawv point-zoo li crater, yog li ua rau kev puas tsuaj rau qhov chaw. Hom kev hnav no feem ntau yog ze rau qhov loj ntawm lub siab, cov yam ntxwv ntawm lub tshuab, cov khoom siv, qhov loj thiab lwm yam.
Thaum tshav kub kub zoo li hnav yog cov khoom hauv cov txheej txheem kev sib txhuam tsim los ntawm cov cua sov ntawm cov khoom, kom cov khoom muaj tempering softening, scorching crease thiab lwm yam tshwm sim. Hom kev hnav no feem ntau tshwm sim nyob rau hauv kev kub ceev thiab kev kub ceev zawv zawg kev sib txhuam, hnav yog kev puas tsuaj ntau dua, thiab nrog rau cov xwm txheej ntawm kev hnav tsoos tsho.
Corrosion hnav yog tshuaj lom neeg, uas yog, tshuaj corrosion los ntawm hnav. Thaum lub npoo ntawm cov khoom thiab cov kua qaub, alkali, ntsev los yog cov pa phem, nws yuav yog tshuaj lom neeg yaig, los yog qhov chaw ntawm cov khoom thiab cov pa oxygen ua ke los ua kom yooj yim poob tawm ntawm cov tawv tawv thiab nkig hlau oxide thiab ua rau cov khoom hnav.
Kev hloov pauv theem yog ib feem ntawm kev ua haujlwm mus sij hawm ntev ntawm qhov kub thiab txias, qhov chaw ntawm qhov chaw ntawm cov ntaub so ntswg hlau ua kom sov ua kom loj, cov ciam teb ntawm cov oxidation, ua rau cov khoob me me, kom cov khoom tawg yooj yim, hnav tsis kam, ua rau cov khoom hnav. .
