Koho Viscosity a me ke kumu o ka aila pauma

ʻO ka maikaʻi o ka ʻaila pauma maʻamau e hilinaʻi nui ʻia i ka viscosity a me ke degere vacuum, a ʻo ka degere vacuum e pili ana i ka waiwai ma lalo o nā kūlana wela.ʻO ke kiʻekiʻe o ka mahana, ʻoi aku ka paʻa o ka hana o ka vacuum degree ka ʻaila maikaʻi.

Paipai ʻia ka ʻaila ʻaila viscosity range
1. Hiki ke hoʻohana i ka ʻaila ʻenekini maʻamau, a hoʻohana i nā huahana ʻaila me nā māka viscosity o V100 a me V150.
2. Hoʻohana ʻo Rotary vane vacuum pump (type 2X) i ka ʻaila V68, V100 viscosity grade.
3. Hoʻohana ʻia ka ʻaila ʻaila viscosity V46 a me V68 i hui pū ʻia me ka rotary vane pump (type 2XZ).
4. Ke koho nei ka pahe'e valve vacuum pump (type H) V68, V100 viscosity grade oil.
5. Hoʻohana ʻia nā ʻaila ʻaila viscosity V100, V150 ʻo Trochoidal vacuum pumps (YZ, YZR).
6. No ka hoʻomaʻamaʻa ʻana i ka ʻōnaehana hoʻoili o nā Roots vacuum pump (mechanical booster pump), hiki ke hoʻohana ʻia ka ʻaila ʻaila V32 a me V46.

ʻO ke kumu o ka koho viscosity
ʻO ke koho ʻana i ka ʻaila viscosity kekahi o nā mea koʻikoʻi no ka hana ʻana o ka pauma vacuum.ʻO ka viscosity o ka wai ke kūʻē i ke kahe ʻana o ka wai, a i ʻole ka friction kūloko o ka wai.ʻOi aku ka nui o ka viscosity, ʻoi aku ka nui o ke kūʻē i ka wikiwiki o ka neʻe ʻana o nā ʻāpana like ʻole,
Piʻi ka mahana, a nui ka nalowale o ka mana;liʻiliʻi loa ka viscosity, a ʻilihune ka hana hoʻopaʻa ʻana o ka paila, e hoʻoheheʻe ʻia ai ke kinoea a me ka pōʻino o ka vacuum.No laila, he mea koʻikoʻi loa ke koho ʻana i ka ʻaila viscosity no nā ʻano pauma vacuum.ʻO ke kumu o ke koho ʻana i ka ʻaila viscosity:
1. ʻO ke kiʻekiʻe o ka wikiwiki o ka paila, ʻoi aku ka haʻahaʻa o ka viscosity o ka ʻaila i koho ʻia.
2. ʻO ke kiʻekiʻe o ka laina laina o ka rotor o ka paila, ka haʻahaʻa o ka viscosity o ka ʻaila i koho ʻia.
3. ʻO ka ʻoi aku ka maikaʻi o ka mīkini ʻana i nā ʻāpana pauma a i ʻole ka liʻiliʻi o ke āpau ma waena o nā ʻāpana friction, ʻoi aku ka haʻahaʻa o ka viscosity o ka ʻaila i koho ʻia.
4. I ka hoʻohanaʻiaʻana o ka pahū maʻemaʻe i nā kūlana wela kiʻekiʻe, pono e koho i kaʻaila viscosity kiʻekiʻe.
5. No nā ʻume māma me ka holo ʻana o ka wai hoʻoluʻu, ʻoi aku ka maʻamau e hoʻohana i ka ʻaila me ka haʻahaʻa viscosity.
7. No nā ʻano ʻē aʻe o ka ʻaila ʻaila, hiki ke koho ʻia e like me kona wikiwiki, ka hoʻoponopono pololei ʻana, ka ʻaila hope loa, etc.

ʻIkepili Viscosity a me Viscosity
ʻO ka mea maʻamau, manaʻo ka poʻe ʻoi aku ka "viscous" o ka vacuum, ʻoi aku ka maikaʻi.ʻOiaʻiʻo, ʻaʻole kēia ka hihia.ʻO ka "Thin" a me ka "sticky" he nānā ʻike pili wale nō a me ka manaʻo lima o DVC, DVE VG22, 32, a me 46, ʻaʻohe ʻikepili helu.Inā like nā waiwai viscosity o nāʻailaʻelua ma 40 ° C, i ka wā e hoʻomaha ai nāʻaila i ka mahana wela,ʻoi aku ka maikaʻi o kaʻaila "thin" ma mua o kaʻaila "sticky".No ka mea, ʻoi aku ka kiʻekiʻe o ka ʻaila "thin" ma mua o ka ʻaila "sticky".Hoʻololi nui ka viscosity o ka ʻaila viscous me ka hoʻololi ʻana o ka mahana, ʻo ia hoʻi, he haʻahaʻa ka viscosity index, a ʻo ka viscosity index he hōʻailona koʻikoʻi o ka ʻaila paila.ʻO nā ʻaila pauma me kahi index viscosity kiʻekiʻe he liʻiliʻi ke ʻano o ka viscosity me ka mahana.Eia kekahi, maʻalahi ka hoʻomaka ʻana o ka paila anu a loaʻa ka hopena o ka mālama nui ʻana i ka ikehu.ʻOi loa i ke kauwela, e like me ka piʻi ʻana o ka mahana ambient a me ka mahana o ka aila i ka paila, hiki i ka palena palena o ka ʻaila ke mālama i kahi hopena maikaʻi.
