Amavuta y'ibanze
NLGI yamavuta niki iyo igeze kumavuta?
Ikigo cy'igihugu gishinzwe gusiga amavuta (NLGI) cyashyizeho urwego rwihariye rwo gusiga amavuta. Umubare uhoraho wa NLGI (uzwi ku izina rya “NLGI urwego”) ku gipimo cyo gukomera ugereranije n'amavuta akoreshwa mu gusiga. Umubare munini wa NLGI bivuze ko amavuta arushijeho gukomera / kubyimbye.
Guhoraho ni igipimo cyimiterere yibanze yamavuta yerekana amavuta akomeye, ashobora guhindurwa muguhindura ibibyimbye.
Umubare uhoraho wa NLGI wonyine ntabwo uhagije kugirango ugaragaze amavuta asabwa na porogaramu runaka. Buri gihe reba igitabo cya nyiracyo kubwoko bwamavuta asabwa.
Imbonerahamwe ikurikira irerekana NLGI itondekanya kandi igereranya buri cyiciro nibicuruzwa byo murugo bihuye.

Icyiciro cya NLGI 000-NLGI 0 amavuta
Gusaba: NLGI Icyiciro 000-NLGI 0 birasabwa kumuvuduko mwinshi, imirimo iremereye na sisitemu ifunze.
Ibyiza: Imikorere idasanzwe yo gusiga, pompe nziza, gusohora neza.
Ibibi: Biroroshye kugaragara gutandukanya amavuta.
NLGI 1-2
Mubisanzwe NIGI 2 nibisanzwe kandi bizwi cyane guhuza amavuta menshi, ni amavuta asanzwe. Ariko mubikorwa bifatika, porogaramu zitandukanye cyangwa ibikoresho bitandukanye bizakenerwa amavuta atandukanye ya NLGI.
Ibyiza: Urwego runini rwa porogaramu, ituze ryiza
Guhoraho NLGI urwego isc Viscosity
Umukiriya abaza ： ndimo gushakisha amavuta menshi ...
Uruganda rwa Lubircant ： Urashaka amavuta menshi "akomeye" cyangwa amavuta menshi "stickier"?
Umukiriya ： Ni irihe tandukaniro riri hagati yibi byombi?
Ubwa mbere amanota ya NLGI (Consistency & Penetration) ni kubicuruzwa bya Grease gusa
Kandi viscosity ni iy'amavuta yo gusiga cyangwa amavuta yibanze y'ibicuruzwa byamavuta.
Impamyabumenyi ya NLGI itondekanya amavuta yoroshye cyangwa ikomeye, ihagaze kumavuta agaragara.
viscosity itondekanya amavuta yibanze yamavuta, Igena ububobere bwamavuta ， Iyo hejuru cyane, kandi amavuta arikomeye.
Mubisanzwe amavuta 2 ashobora kuba afite urwego rumwe rwa NLGI ariko ibintu bitandukanye cyane-amavuta yibanze, mugihe andi abiri ashobora kuba afite amavuta-fatizo amwe ariko adasa n amanota ya NLGI ， ibyo nibisanzwe mubicuruzwa byamavuta.
Niyo mpamvu twagombaga kumva neza ibyo abakiriya bakeneye.
