ʻO ka ʻaila i hoʻohana ʻia no ka lubrication o nā ʻāpana neʻe i loko o ka compressor refrigeration ua kapa ʻia ʻo ka ʻaila refrigeration, i ʻike ʻia hoʻi ʻo ka ʻaila lubricating. Wahi a nā kūlana o ke Kuhina o ka ʻOihana Petrochemical, aia ʻelima mau papa o nā ʻaila refrigeration i hana ʻia ma Kina, ʻo ia hoʻi, No. 13, No. 18, No. 25, No. 30 a me No. 40 o ke kūlana ʻoihana. I waena o lākou, ʻo nā lubricants compressor refrigeration i hoʻohana pinepine ʻia ʻo No. 13, No. 18 a me No. 25, ʻo nā compressors R12 maʻamau e koho i ka No. 18, ʻo nā compressors R22 maʻamau e koho i ka No. 25.
I loko o ka compressor, ʻehā mau kuleana nui ka lubrication, sila ʻana, hoʻoluʻu ʻana a me ka hoʻoponopono ikehu o ka aila refrigeration.
(1) Ka Lubrication
ʻO ka ʻaila refrigeration i ka hana o ka lubrication compressor, i mea e hōʻemi ai i ke kiʻekiʻe o ka friction a me ke komo ʻana a me ka waimaka o ka hana compressor, a laila e hoʻolōʻihi ai i ke ola lawelawe o ka compressor.
(2) Ke sila ʻana
Hoʻokani ka ʻaila refrigeration i kahi hana sila i loko o ka compressor, i hiki ai i ka piston compressor a me ka ʻili cylinder, ma waena o nā bearings wili e hoʻokō ai i ka hopena sila, i mea e pale ai i ka liki ʻana o ka refrigerant.
(3) Hoʻomaʻalili
Ke lubricated ʻia ma waena o nā ʻāpana neʻe o ka compressor, hiki i ka ʻaila refrigerant ke lawe aku i ka wela i hana ʻia i ka wā o ke kaʻina hana, i mālama ai nā ʻāpana neʻe i kahi mahana haʻahaʻa, a pēlā e hoʻomaikaʻi ai i ka pono a me ka hilinaʻi o ka compressor.
(4) Hoʻoponopono ikehu
No ka mea hoʻopili hau me ka ʻōnaehana hoʻoponopono ikehu, hiki ke hoʻohana i ke kaomi aila o ka ʻaila refrigerant ma ke ʻano he mana o ka mīkini hoʻoponopono ikehu.
ʻO ka mea mua, he aha nā koi o nā lako hoʻomaʻalili ma ka ʻaila hoʻomaʻalili
Ma muli o ka hoʻohana ʻana i nā manawa like ʻole a me nā refrigerants, ʻaʻole like nā lako hoʻomaʻalili ma ke koho ʻana i ka ʻaila hoʻomaʻalili. Eia nā ʻano e pono ai no ka ʻaila hoʻomaʻalili:
1, mānoanoa
ʻO nā ʻano o ka mānoanoa o ka aila refrigeration he mea nui ia, ʻo ka hoʻohana ʻana i nā refrigerants like ʻole e koho i nā ʻaila refrigeration like ʻole. Inā nui loa ka mānoanoa o ka aila refrigeration, e piʻi ka mana friction mechanical, ka wela friction a me ka torque hoʻomaka. Ma ke ʻano ʻē, inā liʻiliʻi loa ka mānoanoa, e hana ia i ka neʻe ʻana ma waena o nā ʻāpana ʻaʻole hiki ke hana i ka ʻili aila e pono ai, i ʻole e hoʻokō i ka lubrication a me ka hopena hoʻoluʻu i makemake ʻia.
2, kiko turbidity
ʻO ke kiko turbidity o ka ʻaila refrigeration, ʻo ia ka wā e hoʻemi ʻia ai ka mahana i kahi waiwai i hoʻokahi, a laila hoʻomaka ka ʻaila refrigeration e hoʻoheheʻe i ka paraffin, a lilo ka ʻaila lubricating i mahana turbid. Pono ka turbidity o nā lako refrigeration i hoʻohana ʻia i loko o ka aila refrigeration ma mua o ka mahana evaporation o ka refrigerant, inā ʻaʻole e hoʻopilikia ia i ka throttle valve a i ʻole e hoʻopilikia i ka hana hoʻoili wela.
3, kiko paʻa
ʻO ka ʻaila refrigerant i nā kūlana hoʻokolohua o ka hoʻomaʻalili ʻana e hoʻōki i ke kahe o ka mahana i ʻike ʻia ʻo ke kiko hau. Pono nā lako refrigeration i hoʻohana ʻia i loko o ke kiko hau o ka ʻaila refrigeration e haʻahaʻa loa (e like me ka compressor R22, pono ka ʻaila refrigeration ma lalo o -55℃), inā ʻaʻole e hoʻopilikia ia i ke kahe o ka refrigerant, e hoʻonui i ke kū'ē ʻana o ke kahe, e hopena ai i ka hoʻoili wela maikaʻi ʻole.
4, kiko uila
ʻO ke kiko lapalapa o ka ʻaila refrigerant ka mahana haʻahaʻa loa e hoʻomehana ʻia ai ka lubricant a hiki i kahi e ʻā ai kona mahu i ka wā e pili ana me ka lapalapa. Pono ke kiʻekiʻe o ka mahana lapalapa o ka ʻaila refrigeration ma mua o ka mahana hoʻopau o 15 ~ 30.℃a ʻoi aku paha, i ʻole e hoʻoulu ai i ke ahi a me ka hoʻopili ʻana o ka ʻaila lubricating.
5, kūpaʻa kemika a me ke kūpaʻa oxygen
ʻO ka ʻaila lubricating maʻemaʻe he paʻa, ʻaʻole ia e hoʻopau i ka metala, ʻaʻole ia e hoʻopau i ka oxidation, ʻaʻole ia e hōʻino i ka metala. Eia nō naʻe, inā loaʻa ka refrigerant a i ʻole ka wai i loko o ka lubricant, e hoʻopau ka oxidation o ka lubricant i ka waikawa, a e hōʻino i ka metala. Ke hoʻohana ʻia ka lubricant i nā mahana kiʻekiʻe, e loaʻa ka coke, inā pili kēia mea i ka papa valve, e hoʻopilikia i ka hana maʻamau o ka papa valve, a i ka manawa like e hoʻopau ai i ka kānana a me ka valve throttle. No laila, pono e koho ʻia me ke kūpaʻa kemika a me ke kūpaʻa oxidation he lubricant maikaʻi loa ia.
6, ka makū a me nā mea haumia mechanical
Inā loaʻa ka wai i loko o ka ʻaila lubricating, e hoʻonui i nā loli kemika i loko o ka ʻaila, no laila e hōʻino ka ʻaila, e hopena i ka pala o ka metala, akā i loko o ka throttle valve a i ʻole ka hoʻonui valve e hana i ka "blocking hau". Loaʻa i ka ʻaila lubricating nā haumia mechanical, e hoʻonui i ka ʻaʻahu ʻili friction o nā ʻāpana neʻe, a e ālai koke i ka kānana a me ka throttle valve a i ʻole ka hoʻonui valve, no laila ʻaʻole pono e loaʻa i ka ʻaila lubricating freezer nā haumia mechanical.
7, hana hoʻokaʻawale
I loko o ka pahu hau pani hapa-pani a pani piha ʻia, hoʻopili pololei ʻia ka ʻaila lubricating hau a me ka refrigerant a me nā wili motika a me ka hopena, no laila e koi ʻia ai ka lubricant i nā waiwai insulating maikaʻi a me ke kiʻekiʻe breakdown voltage voltage. Maikaʻi ka hana insulation aila lubricating maʻemaʻe, akā aia ka wai, nā haumia a me ka lepo, e hoʻemi ʻia kāna hana insulation, a ʻo nā koi laulā o ka pahu hau lubricating aila breakdown voltage voltage o 2.5KV a ʻoi aku paha.
8, ma muli o nā ʻano like ʻole o nā ʻano refrigerants, ʻokoʻa loa ka mahana hana o ka ʻōnaehana refrigeration, hiki ke koho ʻia ka lubricant freezer ma kēia ʻano: hiki ke koho ʻia ka viscosity a me ka hau haʻahaʻa o nā lubricants i nā kūlana haʻahaʻa o ka mahana o nā lako refrigeration; a pono e koho ʻia ka viscosity a me ka hau kiʻekiʻe o nā lubricants i nā kūlana wikiwiki a i ʻole ke ea hoʻoluʻu o nā lako refrigeration.
二、 Nā kikoʻī no ka hoʻohana ʻana i ka ʻaila hoʻomaʻalili compressor
1. Hiki i ka ʻōnaehana ea hoʻoluʻu HFC-134a (R-134a) a me nā ʻāpana HFC-134a (R-134a) ke hoʻohana wale i ka ʻaila refrigerant i kuhikuhi ʻia. E hoʻopilikia ka ʻaila refrigeration i hoʻoponopono ʻole ʻia i ka hopena lubrication o ka compressor, a ʻo ka hui ʻana o nā ʻano ʻaila refrigeration like ʻole e hiki ai ke hana i ka oxidation a me ka hāʻule ʻana o ka ʻaila refrigeration, kahi e alakaʻi ai i ka hāʻule ʻana o ka compressor.
2. Ua ʻōlelo ʻo HFC-134a (R-134a) hiki i ka ʻaila hoʻomaʻalili ke omo koke i ka makū mai ka lewa. E ʻoluʻolu e hahai i kēia mau hana:
(1) I ka wā e wehe ai i nā ʻāpana hoʻomaʻalili mai nā lako hoʻomaʻalili, pono e uhi ʻia (sila ʻia) nā ʻāpana i ka wā hikiwawe e hōʻemi i ke komo ʻana o ka makū i ka lewa.
(2) I ke kau ʻana i nā ʻāpana hoʻomaʻalili, mai wehe (a wehe paha) i ka uhi o nā ʻāpana ma mua o ka hoʻohui ʻana iā lākou. E ʻoluʻolu e hoʻohui i nā ʻāpana kaapuni hoʻomaʻalili i ka hikiwawe loa e hōʻemi i ke komo ʻana o ka makū i ka lewa.
(3) ʻO nā mea hoʻoluʻu i kuhikuhi ʻia i mālama ʻia i loko o nā pahu i sila ʻia wale nō ka mea hiki ke hoʻohana ʻia. Ma hope o ka hoʻohana ʻana, e sila koke i ka pahu hoʻoluʻu. Inā ʻaʻole i sila pono ʻia ka mea hoʻoluʻu, ʻaʻole hiki ke hoʻohana hou ʻia ma hope o ke komo ʻana o ka makū.
3. Mai hoʻohana i ka ʻaila refrigerant i hōʻino ʻia a ʻinoʻino, no ka mea e hoʻopilikia ia i ka hana maʻamau o ka compressor.
4. Pono ka ʻōnaehana e hoʻohui i ka ʻaila refrigerant e like me ka nui i kuhikuhi ʻia. Inā haʻahaʻa loa ka ʻaila refrigerant, e hoʻopilikia ia i ka lubrication o ka compressor. ʻO ka hoʻohui ʻana i ka nui o ka ʻaila refrigerant e hoʻopilikia pū i ka hiki ke hoʻoluʻu o ka ʻōnaehana ea hoʻoluʻu.
5. I ka hoʻohui ʻana i ka refrigerant, pono e hoʻohui mua ʻia ka ʻaila refrigerant, a laila e hoʻohui ʻia ka refrigerant
