Yog hais tias cov khoom nto roughness tsawg dhau los yog lub lubrication zoo dhau lawm, nws yuav ua rau cov khoom "slip" thiab wrinkle. Kev sib txhuam ntxiv tuaj yeem txo cov khoom ntws zoo.
5.Koj tuaj yeem kuaj xyuas cov teeb meem wrinkling sai li cas?
Ua ntej, paub meej tias cov khoom siv: ceev nrooj xyuas cov khoom qib thiab qhov chaw saum npoo. Yog tias cov khoom nto du dhau lawm (tsis tshua muaj roughness), lossis yog tias cov khoom siv tshiab tau siv (xws li, los ntawm DC04 mus rau cov khoom siv), qhov no yog qhov ua rau.
Tom ntej no, xyuas cov pwm: Saib xyuas cov duab thiab qhov chaw ntawm wrinkles.

Yog hais tias cov wrinkles nyob rau sab hauv ntawm qhov chaw, thiab pom tseeb qhov tsis sib xws, pom qhov tseem ceeb ntawm kev kuaj xyuas kev taw qhia 2 (pwm clearance).
Yog hais tias cov wrinkles nyob rau ntawm phab ntsa ntawm ib tug complex sib sib zog nqus - kos ib feem, kev taw qhia 3 (kos hlaws dai) feem ntau yog qhov tseem ceeb.
Thaum kawg, xav txog kev kho cov txheej txheem: Yog tias cov txheej txheem saum toj no tsis ua haujlwm, thiab muaj cov khoom siv ntau dhau ntawm qhov chaw wrinkle, xav txog ntxiv "suction ribs" nyob rau hauv qhov chaw tsis pom zoo kom nqus cov khoom ntau dhau, lossis tsim cov txheej txheem sib txawv los hloov cov khoom noj khoom noj.
