Pono e ʻike: ʻO ke kūlike o ka momona

Ke koho ʻana i ke kūlike kūpono oʻaila no kahi noiHe mea koʻikoʻi, no ka mea, hiki ke neʻe aku ka ʻaila palupalu mai kahi e pono ai ke lubricated, ʻoiai ʻo ka momona ʻoʻoleʻa ʻaʻole hiki ke neʻe maikaʻi i nā wahi e pono ai ke lubricated.

ʻO ka mea maʻamau, ʻike ʻia ka ʻoʻoleʻa o ka momona e kona waiwai komo a loiloi ʻia me ka hoʻohana ʻana i ka palapala kiʻekiʻe National Lubricating Grease Institute (NLGI).ʻO ka helu NLGI kahi ana o ke kūpaʻa o ka momona e like me ka mea i hōʻike ʻia e kona waiwai komo i hana ʻia.

ʻO kahoao komoana i ka hohonu o ka hāʻule ʻana o ka cone maʻamau i loko o kahi hāpana momona i ka hapaʻumi o nā millimeters.ʻO kēlā me kēia māka NLGI e pili ana i kahi pae waiwai komo i hana ʻia.ʻO nā waiwai komo kiʻekiʻe, e like me nā mea ma luna o 355, hōʻike i kahi helu NLGI haʻahaʻa haʻahaʻa.Aia ka pālākiō NLGI mai ka 000 (semi-fluid) a i ka 6 (paʻa paʻa e like me ka laha cheese cheddar).

ʻO ka viscosity aila kumu a me ka nui o ka mānoanoa e hoʻoikaika nui i ka helu NLGI o ka momona lubricating i hoʻopau ʻia.ʻO nā mea mānoanoa i loko o ka momona e like me ka sponge, e hoʻokuʻu i ka wai lubricating (ʻaila kumu amea hoʻohui) ke hoʻohana ʻia ka ikaika.

ʻO ke kiʻekiʻe o ke kūlike, ʻoi aku ka paʻa o ka momona i ka hoʻokuʻu ʻana i ka wai lubricating ma lalo o ka ikaika.ʻO ka momona me ka liʻiliʻi e hoʻokuʻu i ka wai lubricating me ka maʻalahi.He mea koʻikoʻi ka paʻa ʻana o ka momona kūpono no ka hōʻoia ʻana e hāʻawi ʻia ka nui kūpono o ka lubricating fluid a mālama ʻia i loko o ka ʻōnaehana no ka lubrication kūpono. 

A chart that lists the worked penetration scores of different NLGI grades as well as an analogy of the consistency of each grade. Grade 000 is like ketchup, Grade 00 is like yogurt, and Grade 0 is like mustard.

NLGI Papa 000-0

Hoʻokaʻawale ʻia nā momona e hāʻule ana ma lalo o kēia mau māka i loko o ka wai i ka laulā semi-fluid a ʻoi aku ka liʻiliʻi o ka viscous ma mua o nā mea ʻē aʻe.Hiki ke hoʻohana ʻia kēia mau māka o ka momona i nā noi i hoʻopaʻa ʻia a kikowaena, kahi ʻaʻole pilikia ka neʻe ʻana o ka momona.No ka laʻana, pono ka pahu pahu i ka momona i loko o kēia ʻano NLGI e hoʻopiha mau i ka lubricant i loko o ka wahi pili.

A chart that lists the worked penetration scores of different NLGI grades as well as an analogy of the consistency of each grade. Grade 1 is like tomato paste, Grade 2 is like peanut butter, and Grade 3 is like margerine spread.

NLGI Papa 1-3

ʻO ka momona me ka helu NLGI o ka 1 he ʻano like ia e like me ka paʻi kōmato, kahi o ka momona me ka māka NLGI o 3 e like me ka pata.ʻO nā momona maʻamau i hoʻohana ʻia, e like me nā mea i hoʻohana ʻia i nā bearings kaʻa, e hoʻohana i ka lubricant ʻo ia ka NLGI grade 2, nona ka ʻoʻoleʻa o ka pata pīni.Hiki i nā māka i loko o kēia pae ke hana ma kahi pae wela kiʻekiʻe a ma nā wikiwiki kiʻekiʻe ma mua o nā māka NLGI 000-0.ʻO nā momona no nā bearingsʻO ka maʻamau ka papa NLGI 1,2, a i ʻole 3.

A chart that lists the worked penetration scores of different NLGI grades as well as an analogy of the consistency of each grade. Grade 4 is like hard ice cream, Grade 5 is like fudge, and Grade 6 is like cheddar cheese.

NLGI Papa 4-6

ʻO nā māka NLGI i hoʻokaʻawale ʻia ma ka laulā 4-6 e like me ka ice cream, fudge a i ʻole cheddar cheese.No nā hāmeʻa e neʻe ana i ka wikiwiki kiʻekiʻe (ʻoi aku ma mua o 15,000 mau ʻōwili i kēlā me kēia minuke) pono e noʻonoʻo ʻia kahi ʻaila NLGI grade 4.ʻOi aku ka ʻike o kēia mau mea hana i ka friction a me ka hoʻokumu ʻana o ka wela, no laila e pono ai kahi ʻaila ʻoi aku ka ʻoi aku ka paʻakikī.ʻOi aku ka maʻalahi o ka hoʻokuʻu ʻia ʻana o nā mea momona mai ke ʻano i ka wā e kaʻa ai, no laila ke alakaʻi nei i ka liʻiliʻi o ka huʻi ʻana a me ka loaʻa ʻana o ka mahana.No ka laʻana, ʻo Nye's Rheolube 374C he ʻaila NLGI grade 4 i hoʻohana ʻia i nā noi lawe wikiwiki kiʻekiʻe me kahi ākea ākea o -40°C a 150°C.ʻAʻole hoʻohana maʻamau ʻia nā momona me kahi NLGI Grade o 5 a i ʻole 6 i nā noi.
