ʻO ka hoʻohālikelike ʻana i ka ikaika axial i nā pauma centrifugal multistage he ʻenehana koʻikoʻi e hōʻoia i ka hana paʻa. Ma muli o ka hoʻonohonoho ʻana o nā impellers, hōʻiliʻili nui nā mana axial (a hiki i kekahi mau tons). Inā ʻaʻole i kaulike pono ʻia, hiki i kēia ke alakaʻi i ka lawe nui ʻana, hōʻino i ka sila, a i ʻole ka hemahema o nā lako. Ma lalo iho nei nā ʻano hana kaulike axial force maʻamau, me kā lākou mau loina, pono, a me nā hemahema.
1.ʻO ka hoʻonohonoho hoʻopololei like ʻole (Hoʻi i hope / Maka-a-maka)
I ka hoʻolālā ʻana o ka ʻōnaehana kaulike axial o ka pauma centrifugal hou, koho ʻia ka pae impeller ma ke ʻano he helu like, no ka mea, i ka wā o ka pae impeller he helu like, hiki ke hoʻohana ʻia ke ʻano hoʻohele impeller symmetrical e kaulike i ka ikaika axial o nā mea hana, a ʻo ka ikaika axial i hana ʻia e ka impeller i hoʻokaʻawale ʻia i ka symmetrically i hoʻokaʻawale ʻia i ka impeller i ke kaʻina hana e like a like me ka oppositurium. mokuʻāina ma ka pae macroscopic. I ke kaʻina hana o ka hoʻolālā, pono e hoʻomaopopo ʻia ʻo ka nui throttling sealing ma mua o ka inlet o ka impeller reverse e kūlike me ke anawaena o ka impeller e hōʻoia i ka sila maikaʻi.
●Kumukānāwai: Hoʻonohonoho ʻia nā impeller e pili ana i nā ʻaoʻao ʻē aʻe i hiki i ko lākou mau axial ikaika ke hoʻopau i kekahi i kekahi.
●Hoʻi hope: ʻElua pūʻulu o nā impeller i hoʻokomo like ʻia a puni ka ʻaoʻao waena o ka pahu pamu.
●He alo a he alo: Hoʻonohonoho ʻia nā impeller e kū pono ana i loko a i waho paha i kahi hoʻonohonoho aniani.
●Nā pono: ʻAʻole pono nā mea hana hou; hale maʻalahi; kiʻekiʻe ke kaulike kaulike (ma luna o 90%).
●Nā pōʻino: Hoʻolālā hale pāpaʻi paʻakikī; paʻakikī o ke ala kahe; pili wale no i na pauma me ka helu kaulike.
●Nā noi: ʻO nā paila kīʻaha kiʻekiʻe kiʻekiʻe, ʻo nā pāpaʻi hoʻoheheʻe kiʻekiʻe.
2. Pahu Kaulike
ʻAʻole i loaʻa i ka ʻōnaehana pahu kaulike (i ʻike ʻia ʻo ka piston balance) kahi ʻae holo axial paʻa, hiki ke uku i ka hapa nui o ka axial thrust, akā ʻaʻole nā mea āpau axial, a ʻaʻohe uku hou i ka wā e neʻe ai i ke kūlana axial. E loaʻa i kēia hoʻolālā ka recirculation kūloko kiʻekiʻe (leakage kūloko) akā ʻoi aku ka hoʻomanawanui i ka hoʻomaka ʻana, pani ʻia, a me nā kūlana transient ʻē aʻe.
●Kumukānāwai: Hoʻokomo ʻia kahi pahu cylindrical ma hope o ka impeller pae hope. Leʻaleʻa ka wai kaomi kiʻekiʻe ma waena o ka pahu a me ka pahu i loko o kahi keʻena haʻahaʻa haʻahaʻa, e hana ana i ka ikaika kū'ē.
● Anā pono: Hiki ke hoʻohālikelike ikaika, kūpono no nā pāpaʻi kiʻekiʻe, multistage pumps (e laʻa, 10+ pae).
●Nā pōʻino: Leakage poho (~ 3-5% o ka kahe kahe ana), e hoemi ana i ka pono. Pono nā paipu kaulike hou a i ʻole nā ʻōnaehana recirculation, e hoʻonui ana i ka paʻakikī o ka mālama ʻana.
●Nā noi: ʻO nā paila centrifugal nui (e laʻa, nā paipu laina lōʻihi).
3.Kōpae kaulike
Ma ke ʻano he ʻano hoʻolālā maʻamau i ke kaʻina hana hoʻolālā axial force balance device o ka pauma centrifugal multistage hou, hiki ke hoʻoponopono ʻia ke ʻano disc balance e like me ke koi hana, a ʻo ka ikaika kaulike e hana nui ʻia e ka ʻāpana cross-section ma waena o ka axial clearance a me ka axial clearance o ka disk, a ʻo ka hapa ʻē aʻe i hana nui ʻia e ka axial disc a me kēia ʻāpana pāʻani ʻelua. o ke kaulike ana i ka ikaika axial. Hoʻohālikelike ʻia me nā ʻano hana ʻē aʻe, ʻoi aku ka maikaʻi o ke ʻano o ka pā kaulike ʻoi aku ka nui o ke anawaena o ka pā kaulike a ʻoi aku ka kiʻekiʻe o ka naʻau, kahi e hoʻomaikaʻi maikaʻi ai i ka hana paʻa o ka mea hana. Eia nō naʻe, ma muli o ka liʻiliʻi o ka holo ʻana o ka axial, hiki ke ʻaʻahu a hōʻino ʻia kēia hoʻolālā ma lalo o nā kūlana transient.
●Kumukānāwai: Hoʻokomo ʻia kahi disk movable ma hope o ka impeller pae hope. Hoʻololi ikaika ka ʻokoʻa puʻe ma waena o ka disk i kona kūlana e pale aku i ka ikaika axial.
●Nā pono: Hoʻololi 'akomi i nā ʻokoʻa ikaika axial; kiʻekiʻe kaulike kaulike.
●Nā pōʻino: ʻO ke kuʻi ʻana ke kumu o ka ʻaʻahu, pono e hoʻololi i ka manawa. Pilikino i ka maʻemaʻe wai (hiki i nā ʻāpana ke hoʻopaʻa i ka disk).
●Nā noi: Nā ʻume wai maʻemaʻe maʻemaʻe o ka pae mua (e hoʻololi mālie ʻia e nā pahu kaulike).
4.ʻO ka pahu kaulike + ka hui ʻana o ka disk
Ke hoʻohālikelike ʻia me ke ʻano o ka pā kaulike, ʻokoʻa ke ʻano o ka pahu pahu kaulike ma muli o ka nui o kāna ʻāpana throttle bushing ʻoi aku ka nui ma mua o ka nui o ka impeller hub, aʻo ka disc balance e koi i ka nui o ka throttle bushing e like me ka nui o ka impeller hub. ʻO ka mea maʻamau, ma ke ʻano hoʻolālā o ka pahu kaulike, ʻo ka ikaika kaulike i hana ʻia e ka pā kaulike e ʻoi aku ma mua o ka hapalua o ka nui o ka axial ikaika, a hiki ke kiʻekiʻe i ka 90% o ka nui axial ikaika, a ʻo nā ʻāpana ʻē aʻe i hāʻawi nui ʻia e ka pahu kaulike. I ka manawa like, ʻo ka hoʻonui haʻahaʻa ʻana i ka ikaika kaulike o ka pahu kaulike e hoʻemi i ka ikaika kaulike o ka pā kaulike, a me ka hoʻohaʻahaʻa ʻana i ka nui o ka pā kaulike, a laila e hōʻemi ana i ka pae ʻaʻahu o ka pā kaulike, hoʻomaikaʻi i ke ola lawelawe o nā ʻāpana, a me ka hōʻoia i ka hana maʻamau o ka multistage centrifugal pump.
●Kumukānāwai: Hoʻohana ka pahu i ka hapa nui o ka ikaika axial, ʻoiai ʻo ka disk e hoʻokani maikaʻi i ke koena ikaika.
●Nā pono: Hoʻohui i ka paʻa a me ka hiki ke hoʻololi, kūpono no nā kūlana hana hoʻololi.
●Nā pōʻino: Kapili paʻakikī; koina kiekie.
●Nā noi: ʻO nā pamu ʻoihana hana kiʻekiʻe (e laʻa, nā pamu hoʻoheheʻe nuklea).
5. Nā Kūʻai Kūlohelohe (Kokua Kokua)
●Kumukānāwai: ʻO nā bearings ball contact angular a i ʻole nā bearings Kingsbury e hoʻopau i ka ikaika axial koena.
●Nā pono: Kākoʻo hilinaʻi no nā ʻano kaulike ʻē aʻe.
●Nā pōʻino: Pono ka lubrication mau; ʻoi aku ka pōkole o ke ola ma lalo o nā ukana axial kiʻekiʻe.
●Nā noi: Nā paila liʻiliʻi liʻiliʻi a i ʻole nā pauma kiʻekiʻe.
6. Papalua-Suction Impeller Design
●Kumukānāwai: Hoʻohana ʻia kahi impeller lua-suction ma ka pae mua a waena paha, e kaulike ana i ka ikaika axial ma o ka lua-ʻaoʻao inflow.
●Nā pono: Ke kaulike kūpono ʻoiai e hoʻomaikaʻi ana i ka hana cavitation.
●Nā pōʻino: Hoʻohālikelike wale i ka ikaika axial pae hoʻokahi; pono nā ʻano hana ʻē aʻe no nā pamu multistage.
7. Puka Kaulike Hydraulic (Impeller Backplate Holes)
●Kumukānāwai: Ua wili ʻia nā puka i loko o ka impeller backplate, e ʻae ana i ka wai kaomi kiʻekiʻe e recirculate i ka ʻāpana haʻahaʻa haʻahaʻa, e hōʻemi ana i ka ikaika axial.
●Nā pono: Maʻalahi a haʻahaʻa ke kumu kūʻai.
●Nā pōʻino: Hoemi i ka pono o ka pauma (~ 2–4%).He kūpono wale no nā noi ikaika axial haʻahaʻa; koi pinepine i nā bearings thrust hou.
