ʻO ka hana o ka paila wai

Ua hoʻomohala ʻia nā pauma wai me ka hoʻomohala ʻana i nā ʻoihana. I ke kenekulia 19, aia nā ʻano piha piha a me nā ʻano ʻano o nā pamu ma waho, i hoʻohana nui ʻia. Wahi a nā helu helu, ma kahi o 1880, ʻoi aku ka nui o ka 90% o ka nui o ka nui o ka pauma centrifugal ka hana ʻana o ka pauma centrifugal, ʻoiai ʻo nā pumps kumu kūikawā e like me nā pauma mana, nā pauma kemika, a me nā pamu mining ma kahi o 10% wale nō. ka huina pau o ka pauma. Ma ka makahiki 1960, he 45% wale no ka nui o ka pauma, a he 55% wale no ka pauma. E like me ke ʻano o ka hoʻomohala ʻana i kēia manawa, ʻoi aku ka kiʻekiʻe o ka pākuʻi o nā pamu kumu kūikawā ma mua o nā pamu kumu maʻamau.

I ka hoʻomaka ʻana o ke kenekulia 20, ua hoʻomohala mua ʻia e ʻAmelika Hui Pū ʻIa e pani i nā puna wai hohonu. Ma hope mai, ua hana pū nā ʻāina ʻEulopa i ka noiʻi a me ka hoʻomohala ʻana, e hoʻomau mau ana a hoʻomaikaʻi mālie. No ka laʻana, hoʻohana ka lua lanahu Rhine brown ma Kelemānia ma luna o 2500 mau pamu uila submersible, me ka mana nui loa i hiki i 1600kw a me ke poʻo o 410m.

Ua hoʻomohala ʻia ka pauma uila submersible i ko mākou ʻāina i ka makahiki 1960, a ma waena o ia mea ua hoʻohana lōʻihi ʻia ka pauma uila submersible ma ka ʻaoʻao hana no ka hoʻoulu ʻana i ka ʻāina mahiʻai ma ka hema, a ua hoʻokumu ʻia nā pauma uila submersible liʻiliʻi a me ka liʻiliʻi. hookomo i ka hana nui. Ua hoʻokomo pū ʻia ka mana nui a me ka voluma kiʻekiʻe a me nā kaʻa uila, a ua hoʻokomo ʻia nā ʻōpala nui me ka mana o 500 a me 1200 kW i loko o nā mines. No ka laʻana, hoʻohana ʻo Anshan Iron and Steel Company i ka pauma uila submersible 500kw e hoʻokahe i ka lua hao hāmama Qianshan, he hopena koʻikoʻi i ka wā ua. Aia nā hōʻailona e hoʻololi i ka hoʻohana ʻana i nā pamu uila i loko o ka wai i loko o nā mines, me ka hiki ke hoʻololi i nā pamu kuʻuna nui. Eia kekahi, ʻoi aku ka nui o ka mana submersible pumps i kēia manawa ma lalo o ka hana hoʻāʻo.

ʻO nā mīkini i hoʻohana ʻia no ka pamu, ka lawe ʻana, a me ka hoʻonui ʻana i ke kaomi o ka wai i kapa ʻia ʻo pumps. Mai ka ikehu ikehu, he mīkini e hoʻololi i ka ikehu mechanical o ka mover prime i ka ikehu o ka wai i lawe ʻia, e hoʻonui ana i ka kahe kahe a me ke kaomi o ka wai.

ʻO ka hana o ka paila wai ka mea maʻamau e huki i ka wai mai ka ʻāina haʻahaʻa a lawe iā ia ma kahi paipu a i ka ʻāina kiʻekiʻe. ʻO kahi laʻana, ʻo ka mea a mākou e ʻike ai i ko mākou ola i kēlā me kēia lā ka hoʻohana ʻana i ka paila no ka paila ʻana i ka wai mai nā muliwai a me nā loko e hoʻoheheʻe i ka ʻāina mahiʻai; No ka laʻana, ka paila ʻana i ka wai mai nā pūnāwai hohonu lalo a hāʻawi i nā hale kiaʻi wai. Ma muli o ka hiki ke piʻi aʻe ke kaomi o ka wai ma hope o ka hele ʻana i ka pā, hiki ke hoʻohana ʻia ka hana o ka paila e huki i ka wai mai nā pahu me ka haʻahaʻa haʻahaʻa a lanakila i ke kū'ē ma ke ala e lawe ai i nā ipu me ka kiʻekiʻe. kaomi a i ʻole nā ​​wahi ʻē aʻe e pono ai. ʻO kahi laʻana, e huki ka wai paila i ka wai mai ka pahu wai haʻahaʻa haʻahaʻa e hānai i ka wai i loko o ka pahu boiler me ke kaomi kiʻekiʻe.

He ākea loa ka pae hana o nā pamu, a hiki i ka nui o ka kahe o nā pamu nunui ke hiki i nā haneli tausani m3 / h a ʻoi aku paha; Aia ma lalo o ka ʻumi ml/h ka kahe kahe o nā pamu micro. Hiki i kona puʻe ke piʻi ma luna o 1000mpa mai ke kaomi lewa. Hiki iā ia ke lawe i nā wai ma nā mahana mai -200℃a oi aku i ka 800℃. Nui nā ʻano wai i hiki ke lawe ʻia e nā pāpaʻi,

Hiki iā ia ke lawe i ka wai (ka wai maʻemaʻe, ka wai ʻino, a me nā mea ʻē aʻe), ka aila, ka wai acid-base, emulsions, suspensions, a me nā metala wai. Ma muli o ka hoʻohana ʻia ʻana o ka hapa nui o nā pumps i ʻike ʻia e ka poʻe i ko lākou ola i kēlā me kēia lā no ka lawe ʻana i ka wai, ua kapa ʻia lākou he mau paila wai. Eia naʻe, ma ke ʻano he huaʻōlelo maʻamau no nā pamu, ʻaʻole maopopo kēia huaʻōlelo.
