pauma centrifugal

He nui nā pōmaikaʻi o nā paila Centrifugal e like me ka laulā o ka hana, ka holo like ʻana, ka hana maʻalahi, ka hana hilinaʻi a me ka mālama pono. No laila, ʻo ka pauma centrifugal ka mea i hoʻohana nui ʻia i ka hana ʻoihana. Ma waho aʻe o ka pānaʻi pānaʻi i hoʻohana mau ʻia i ka wā e hoʻohana ʻia ai ke kaomi kiʻekiʻe a me nā kahe kahe liʻiliʻi a i ʻole ke ana ʻana, hoʻohana mau ʻia nā pamu vortex a me nā pamu hoʻoneʻe maikaʻi ke loaʻa nā wai i loko o ke kinoea, a hoʻohana mau ʻia nā pauma rotor no ka media viscosity kiʻekiʻe, hoʻohana ʻia nā pamu centrifugal. i ka nui o nā kūlana ʻē aʻe.
Wahi a nā helu helu, i ka hana kemika (me ka petrochemical), ʻo ka hoʻohana ʻana i nā pamu centrifugal he 70% a 80% o ka nui o nā pamu.
Pehea ka hana ʻana o nā pamu centrifugal
ʻO ka pauma centrifugal ka mea nui i hoʻokumu ʻia me kahi impeller, kahi pahu, kahi pahu pahu, kahi sila a me kahi apo hoʻopaʻa. ʻO ka maʻamau, pono e hoʻopiha ʻia ka pahu pahū i ka wai ma mua o ka hoʻomaka ʻana i ka pauma centrifugal. I ka wā e hoʻohuli ai ka mea hoʻoneʻe nui i ka pahu pahū a me ka impeller e hoʻololi, e neʻe ka wai i loko o ka pōʻai me ka impeller ma kekahi lima, a ma kekahi ʻaoʻao, e kiola ʻia mai ke kikowaena o ka impeller a i ka ʻaoʻao o waho ma lalo o ka hana o ka ikaika centrifugal. Loaʻa i ka impeller ka ikehu kaomi a me ka ikehu velocity. Ke kahe ka wai i loko o ka volute i ke awa hoʻokuʻu, e hoʻololi ʻia kahi ʻāpana o ka ikehu velocity i ikehu kaomi static. Ke hoʻolei ʻia ka wai mai ka impeller, ua hoʻokumu ʻia kahi wahi haʻahaʻa haʻahaʻa i waenakonu o ka impeller, e hana ana i kahi ʻokoʻa puʻe me ke kaomi ʻana o ka ʻili wai suction, no laila e hoʻomau mau ʻia ka wai i loko a hoʻokuʻu ʻia i kekahi kaomi.

ʻO nā ʻāpana nui o ka pauma centrifugal
(1)
pahu pahu
ʻElua ʻano o ka pahu pahu: axially split type a me radially split type. ʻO nā pahu o ka hapa nui o ka pauma pae hoʻokahi o ke ʻano volute, ʻoiai ʻo nā pahu i hoʻokaʻawale radially o nā pauma multi-stage maʻamau he annular a pōʻai paha.
ʻO ka mea maʻamau, ʻo ka lua o loko o ka pahu volute pump casing he spiral liquid channel, i hoʻohana ʻia e hōʻiliʻili i ka wai i hoʻolei ʻia mai ka impeller a alakaʻi iā ia i ka diffusion tube a i ka puka pā. Hāʻawi ka pahu pahū i ke kaomi hana a pau a me ka ukana wela o ka wai.
(2)
mea hoʻolele
ʻO ka impeller wale nō ka mea hana mana, a hana ka paila i ka wai ma o ka impeller. ʻEkolu mau ʻano impeller: pani ʻia, hāmama, a semi-open. Hoʻokumu ʻia ka impeller i pani ʻia me nā lau, ka uhi mua a me ka uhi hope. Aia ka impeller semi-open i nā lau a me kahi uhi hope. ʻO ka impeller hāmama wale nā ​​lau a ʻaʻohe uhi mua a hope. ʻOi aku ka maikaʻi o nā impellers paʻa, ʻoiai ʻoi aku ka haʻahaʻa o nā impellers hāmama.
(3)
apo hoailona
ʻO ka hana o ke apo sealing e pale i ka leaka o loko a me waho o ka paila. Hana ʻia ke apo hoʻopaʻa i nā mea ʻaʻahu a kau ʻia ma ka mua a me hope o nā pā uhi o ka impeller a me ka pahu pahu. Hiki ke pani ʻia ma hope o ke kau ʻana.
(4)
ʻO nā kumu a me nā Bearings
Hoʻopaʻa ʻia kekahi ʻaoʻao o ka pahu pump me ka impeller, a ua hoʻolako ʻia kekahi ʻaoʻao me kahi hui. Ma muli o ka nui o ka paila, hiki ke hoʻohana ʻia nā bearings rolling a me nā bearings e like me nā bearings.
(5)
Sila lāʻau
Hoʻokomo pinepine nā sila shaft i nā sila mechanical a me nā sila packing. ʻO ka mea maʻamau, ua hoʻolālā ʻia nā pamu e hoʻolako ʻia me nā sila packing a me nā sila mechanical.
