Ka ʻike o ka ʻōnaehana ea kōmi

ʻO ka ʻōnaehana ea kaomi ʻia, ma kahi ʻano haiki, ua haku ʻia me nā lako kumu ea, nā lako hoʻomaʻemaʻe kumu ea a me nā pipeline pili.Ma ka manaʻo ākea, nā ʻāpana kōkua pneumatic, nā mea hana pneumatic, nā ʻāpana mana pneumatic, nā ʻāpana vacuum, etc.ʻO ka mea maʻamau, ʻo nā mea hana o kahi kikowaena air compressor he ʻōnaehana ea paʻa i kahi ʻano haiki.Hōʻike ke kiʻi ma lalo nei i kahi pakuhi ʻōnaehana ea kaomi maʻamau:

ʻO ka mea ea kumu ea (air compressor) omo i ka lewa, compresses i ka ea i loko o ke kūlohelohe kūlana i compressed ea me ka kiʻekiʻe kaomi, a wehe i ka makū, aila a me nā mea haumia 'ē aʻe i loko o ka compressed ea ma o ka hoʻomaʻemaʻe lako.

ʻO ka ea i loko o ke ʻano he hui ʻia o nā kinoea like ʻole (O₂, N₂, CO₂…etc.), a ʻo ka mahu wai kekahi o ia mau mea.ʻO ka ea i loaʻa ka nui o ka mahu wai ua kapa ʻia ka ea humid, a ʻo ka ea i loaʻa ʻole ka mahu wai i kapa ʻia he ea maloʻo.ʻO ka ea a puni mākou he ea maʻemaʻe, no laila, ʻo ke ʻano hana o ka ea compressor he ea maʻa maoli.
ʻOiai he liʻiliʻi ka nui o ka mahu wai o ka ea haʻahaʻa, he mana nui kona ʻike i nā waiwai kino o ka ea humid.I loko o ka ʻōnaehana hoʻomaʻemaʻe ea, ʻo ka hoʻomaloʻo ʻana o ka ea i hoʻopaʻa ʻia kekahi o nā mea nui.

Ma lalo o kekahi mau kūlana wela a me ke kaomi, ua kaupalena ʻia ka ʻike o ka mahu wai ma ka ea haʻahaʻa (ʻo ia hoʻi, ka nui o ka mahu wai).I kekahi mahana, i ka wā e hiki ai ka nui o ka mahu wai i loko o ka mea hiki ke hiki, ua kapa ʻia ka ea humid i kēia manawa.Ua kapa ʻia ka ea maʻemaʻe me ka ʻole o ka nui o ka mahu wai.

I ka manawa e lilo ai ka ea unsaturated i ka ea saturated, e hoʻokuʻu ʻia nā kulu wai wai i ka ea humid, i kapa ʻia ʻo "condensation".He mea maʻamau ka condensation.No ka laʻana, he kiʻekiʻe ka haʻahaʻa o ka ea i ke kauwela, a he maʻalahi ke hana i nā kulu wai ma ka ʻili o ka paipu wai.I ke kakahiaka hoʻoilo, ʻike ʻia nā kulu wai ma nā puka aniani o nā kamaʻāina.Hoʻokumu ʻia kēia mau mea a pau e ka hoʻoluʻu ʻana o ka ea humid ma lalo o ke kaomi mau.Lu mau hopena.

E like me ka mea i ʻōlelo ʻia ma luna, ʻo ka mahana i hiki ai ka ea unsaturated i ka saturation, ua kapa ʻia ʻo ka dew point ke mālama mau ʻia ke kaomi ʻāpana o ka mahu wai (ʻo ia hoʻi, mālama mau ʻia ka ʻike wai piha).Ke hāʻule ka mahana i ka mahana o ka hau, aia ka "condensation".

ʻAʻole pili wale ka hau o ka ea humid i ka mahana, akā pili pū kekahi i ka nui o ka wai i ka ea humid.He kiʻekiʻe ka hau me ka nui o ka wai, a he haʻahaʻa ka hau me ka haʻahaʻa o ka wai.

He mea koʻikoʻi ka hoʻohana ʻana o ka mahana o ka hau i ka ʻenekinia compressor.No ka laʻana, i ka haʻahaʻa haʻahaʻa loa o ka wela o ka puka o ka mea hoʻoheheʻe ea, e hoʻopili ʻia ka hui ʻaila-gas ma muli o ka haʻahaʻa haʻahaʻa i loko o ka pahu aila-ea, kahi e hana ai ka aila lubricating i ka wai a pili i ka hopena lubrication.nolaila.Pono e hoʻolālā ʻia ka wela o ka puka o ka mea hoʻoheheʻe ea ʻaʻole e emi iho ma mua o ka mahana o ka hau ma lalo o ke kaomi ʻāpana.

ʻO ka hau hau ka wela o ka hau ma lalo o ke kaomi o ka lewa.Pēlā nō, pili ka dew pressure i ka wela o ka hau o ka ea kaomi.

ʻO ka pilina pili ma waena o ke kaha hau kaomi a me ka pae dew kaomi maʻamau e pili ana i ka ratio kaomi.Ma lalo o ka lae hau kaomi like, ʻoi aku ka nui o ka lākiō hoʻopiʻi, ʻoi aku ka haʻahaʻa o ka pae hau kaomi maʻamau.

He lepo ka ea compressed e puka mai ana mai loko mai o ka ea.ʻO nā mea hoʻohaumia nui: ka wai (nā kulu wai wai, ka noe a me ka mahu wai kinoea), ke koena o ka ʻaila lubricating noe (nā kulu aila noe a me ka ʻaila hinu), nā haumia paʻa (ka lepo lepo, ka pauka metala, nā kala kala, nā ʻāpana tar a me nā mea kānana, pauda maikaʻi o nā mea hoʻopaʻa sila, a me nā mea ʻē aʻe).

ʻO ka ʻaila lubricating deteriorated e hoʻopōʻino i ka lāʻau, plastik, a me nā mea hoʻopaʻa sila, e hoʻopilikia ai i ka hana o nā valve a me nā huahana haumia.ʻO ka maʻu a me ka lepo e hoʻoheheʻe ʻia nā ʻāpana metala a me nā paipu, e hoʻopaʻa ʻia a mae ʻole paha nā ʻāpana neʻe, e hana ʻino ai nā ʻāpana pneumatic.E ālai pū ka wai a me ka lepo i nā puka throttling a i ʻole nā ​​kānana pale.Ma hope o ka hau e maloʻo ai ka paipu a pohā paha.

Ma muli o ka maikaʻi ʻole o ka ea, ua hoʻemi nui ʻia ka hilinaʻi a me ke ola lawelawe o ka ʻōnaehana pneumatic, a ʻoi aku ka nui o nā poho i ʻoi aku ma mua o ke kumu kūʻai a me ka mālama ʻana i ka mea mālama puna wai, no laila pono pono ke koho pololei i ka mālama ʻana i ka ea. ʻōnaehana.
He aha nā kumu nui o ka wai i loko o ka ea kōmi?

ʻO ke kumu nui o ka wai i loko o ka ea i hoʻopaʻa ʻia ʻo ia ka mahu wai i omo ʻia e ka ea compressor me ka ea.Ma hope o ke komo ʻana o ka ea humid i ka compressor air, e ʻoki ʻia ka nui o ka wai i loko o ka wai wai i ka wā o ke kaʻina hana, e hoʻemi nui i ka haʻahaʻa pili o ka ea i hoʻopaʻa ʻia ma ka puka o ka ea compressor.

No ka laʻana, inā he 0.7MPa ke kaomi ʻana o ka ʻōnaehana a ʻo ka haʻahaʻa pili o ka ea inhaled he 80%, ʻoiai ʻo ka hoʻopuka ʻana o ka ea i hoʻopaʻa ʻia mai ka ea compressor ua hoʻopiha ʻia ma lalo o ke kaomi, inā e hoʻohuli ʻia i ke kūlana o ka lewa ma mua o ke kaomi ʻana, ʻo kona haʻahaʻa pili. wale 6 ~ 10%.ʻO ia hoʻi, ua hoʻemi nui ʻia ka mākū o ka ea i hoʻopaʻa ʻia.Eia nō naʻe, i ka hāʻule mālie ʻana o ka mahana i loko o ka pipeline gas a me nā mea hana kinoea, e hoʻomau ka nui o ka wai wai i ka condense i ka ea i hoʻopaʻa ʻia.
Pehea ka hoʻohaumia ʻana o ka aila i loko o ka ea kōmi?

ʻO kaʻaila lubricating o ka ea compressor, kaʻaila hinu a me kaʻaila i hoʻokuʻuʻia i loko o ka ea a me kaʻaila lubricating o nā mea pneumatic i loko o ka pūnaewele ke kumu nui o ka haumia o kaʻaila i loko o ka ea paʻa.

Koe nae ka centrifugal a me ka diaphragm ea compressors, aneane pau na ea compressors e hoohana nei (me na aila lubricated air compressors) e loaa a emi mai paha ka aila lepo (ka aila droplets, oil mist, oil vapor and carbon fission) i loko o ka paipu kinoea.

ʻO ke kiʻekiʻe o ka wela o ka keʻena hoʻopiʻi o ka ea compressor e hoʻoulu i kahi 5% ~ 6% o ka aila e vaporize, māwae a oxidize, a waiho i loko o ka paia o loko o ka paipu compressor ea i ke ʻano o ke kalapona a me ka varnish film, a e hoʻokuʻu ʻia ka hakina māmā ma ke ʻano o ka mahu a me ka micro.

I ka pōkole, no nā ʻōnaehana ʻaʻole pono i nā mea lubricating i ka wā o ka hana, nā ʻaila āpau a me nā mea lubricating i hui pū ʻia me ka ea compressed i hoʻohana ʻia e hiki ke manaʻo ʻia he mau mea i hoʻohaumia i ka aila.No nā ʻōnaehana pono e hoʻohui i nā mea lubricating i ka wā o ka hana, ʻo nā pena anti-rust a me ka ʻaila compressor i loko o ka ea i hoʻopaʻa ʻia e manaʻo ʻia he mea haumia aila.

Pehea ke komo ʻana o nā haumia paʻa i ka ea kōmi?

ʻO nā kumu nui o nā haumia paʻa i ka ea paʻa:

①Hoʻohui ʻia ka lewa a puni me nā mea haumia like ʻole o nā ʻāpana like ʻole.ʻOiai inā ua hoʻolako ʻia ka port air compressor suction port me kahi kānana ea, ʻo ka maʻamau "aerosol" haumia ma lalo o 5 μm hiki ke komo i ka ea compressor me ka ea inhaled, i hui pū ʻia me ka aila a me ka wai i loko o ka paipu hoʻopau i ka wā o ke kaʻina hana.

②I ka hana ʻana o ka ea compressor, ʻo ka friction a me ka hui ʻana ma waena o nā ʻāpana like ʻole, ka ʻelemakule a me ka hāʻule ʻana o nā sila, a me ka carbonization a me ka fission o ka aila lubricating i ke kiʻekiʻe wela e hoʻoulu i nā ʻāpana paʻa e like me nā ʻāpana metala, lepo lepo a me ka carbonaceous. fission e lawe ʻia i loko o ka paipu kinoea.
