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.

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.

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.
