He aha nā mea'aila a me nā lubricants

Wahi a nā hō'ike i hō'oia'ole'ia, ho'ohana'ia nā lubricants e nā kānaka ma mua o 6,000 mau makahiki i hala. Ua'ike'ia'o ka'aila i ka manawa lō'ihi, akā, ua ho'omaka koke'ia ma ka ho'oma'ema'e'ana i ka'aila, a'a'ole he nīnau no ka hana'ana. I ka'ike'ana o nā kānaka i ke'ano o ka ho'oponopono'ana, ua lawe wale lākou i ka kerosene, a me ka'aila maika'i loa - ho'ohana'ia i mea'ai a puhi'ia paha. A i ka 90% o ka nui o ka'aila.

Akā,'a'ole i kū malie ka'enehana - a ma kēia manawa i ka'aila mea'aila, ua a'o lākou e māhele i ka'aila hinu ma nā'oko'a'ē a'e. Ma hope o ka hana'ana i'āpono'ia e loa'a mai iā ia nā mea waiwai nui, i kapa'ia he'aila a hinu'aila paha. I nā ka'a ka'a hou o kēia mau mea - nā hanahana mechanical ki'eki'e, no laila,'o nā mea momona a me nā lubricants no lākou e pono e ho'okō i kekahi mau koi.

Ho'onui i ka maika'i o ka'aila lubricating ma ka ho'oulu'ana i nā mea pono (additives) i ia mea. Ho'ohui kēia mau mea ho'ohālikelike i ho'okahi mau manawa i ka manawa ai'ole i kekahi manawa. Eia kekahi la'ana, ua ho'okomo'ia nā mea'oni'oki a me nā lubricants e ho'onā i ke kaumaha o nā mea hana, a me nā mea pale - ho'emi i ka nui o ka waiho'ana a pale i nā piston mai ka wela. I nā lālā lubricating hou, hiki iā'oe ke helu i nā'umi a'e ma mua o ka nui.

Ma muli o ka laulā o nā mea ho'okomo a me ka hiki ke ho'ohui'ia, ua ho'onui'ia ke'ano i hā'awi'ia e nā mea hana. 'O kēia nā lubricating'aila e ho'oku'u'ia. A eia kekahi, he nui o nā hi'ohi'ona o lākou i'ike'ia -'o ka hua, ka lawe'ana, a me nā mea'ē a'e. Ma mua o ka kū'ai'ana aku i nā lubricants ('oiai kekahi mea hana limahana kaulana), pono'oe e'ike i nā'ano kumu o kā lākou koho.

Lubricants i nui kiko'î i hoakaka ia ma ka oaoieei-ano, akā, me ka mea kūʻai mea pono e hoʻolohe wale nō i ka mau o ka ia. 'O ka laulā o ka'aila e hō'ike i ka laulima o kāu ka'a me kēia mea, a me ka viscosity - no kona kūpono no ka ho'ohana'ana i kahi a me ke kau.

E ho'oholo i kēia inā he lubricant, e kōkua i ke kahaka'ana, e hō'ike ana i kahi māka waiwai, me ka pūnaewele hō'ulu'ulu honua like. Ma nā kū'oko'a'ē a'e,'o ka'enehana no ka'ike a me ka hō'ike'ana i ka hō'ailona viscosity e hō'ike'ia e ke'ano i ho'ohana'ia e ka American Society of Automotive Engineers SAE, no laila,'a'ole hiki ke koho'ia aia ma hope o ka hō'ike'ana o nā maka'āinana SAS. Ho'ohālikelike'ia nā papa ho'olālā o nā mea puhi me nā lubrication e ka huapalapala W, a me nā kauwela - ma ka hō'ike'ana i ka viscosity.

Aia kekahi mau ho'ona'auao ma'amau. Eia kekahi la'ana, ma lalo o ke koho inoa SAE J300, aia he'eono mau hanana viscosity o ke'ano ho'oilo - 0W, 5W, 10W, 15W, 20W, 25W. Ke hō'oia nei kēia mau papa a pau i ka ho'omaka'ana o ka mīkini ma ke'ano ma'amau, a ua ka'awale ka holo'ana o ka mea'ai a me nā lubricants ma waena o ke kikowaena i nā'ano wela -30- + 5. 'O nā'ano kau wela'a'ole i loa'a nā leka hou i ka lepili'ana, akā me ka pi'i'ana o ka pehuhi nui, ua māhele'ia kēia mau māka a pau i nā papa SAE: 20, 30, 40, 50, 60.

I kēia manawa,'ike'oe i ka lā'au a me nā lubricants a me ka ho'ohālikelike'ana o lākou!
