ʻAno D ʻano pāpaʻi pāpaʻi centrifugal multistage

1. Hoʻohana

ʻO nā 1.1 D a me nā pāpaʻi DC he mau papa centrifugal he nui.He kūpono ia no ka lawe ʻana i ka wai (me ka nui o nā ʻano like ʻole o ka liʻiliʻi ma mua o 1%. ʻO ka liʻiliʻi o ka nui ma lalo o 0.1 mm) a me nā wai ʻē aʻe e like me ka wai i ka wai.

ʻAʻoleʻoi aku ka nui o ka mahana o ka D-type transport medium ma mua o 80 ° C. He kūpono ia no ka hoʻokahe wai wai a me nā hale hana, ka wai o ke kūlanakauhale a me nā manawa'ē aʻe.

ʻAʻole iʻoi aku ka nui o ka mahana o ka DG pump conveying medium ma mua o 105 ° C. He kūpono ia no nā paila liʻiliʻi e paʻi i nā paila paila a lawe i ka wai wela like.1.2 Ka pae hana o kēia pūʻulu (e like me nā lula):…

kahe: 6.3 ~ 450m³/h

hāpai: 50 ~ 650M

2. Hōʻike Hoʻolālā

ʻO kēia ʻano pāpaʻi ka mea nui i ka ʻāpana shell, ʻāpana rotor, ʻāpana kaulike, ʻāpana lawe a me nā ʻāpana sila.

1. ʻāpana pūpū

ʻO ka hapa o ka pūpū ka mea nui i ka ʻāpana suction, ka ʻāpana waena, ka ʻāpana hoʻokuʻu, ka vane alakaʻi, ke kino halihali, a me nā mea i hoʻopili ʻia e nā bolts.ʻO ka ʻaoʻao o ka hoʻololi ʻana o ka paila, ke nānā ʻia mai ka hopena o ka hoʻokele, huli ka paila i ka uaki.

2. ʻāpana Rotor

ʻO ka hapa o ka rotor ka mea nui i ka lāʻau a me ka impeller i kau ʻia ma ke kumu, ka lima lima, ka disc balance a me nā ʻāpana ʻē aʻe.Hoʻopaʻa ʻia nā ʻāpana o ka lāʻau me nā kī pālahalaha a me nā nati lima e hoʻohui ʻia me ke kumu, a kākoʻo ʻia ka rotor holoʻokoʻa i ka pahu pahu e nā bearings ma nā ʻaoʻao ʻelua.Hoʻokumu ʻia ka helu o nā impellers i ka hui rotor ma ka helu o nā pae pahū.

Ke hoʻohana ʻia kēia ʻano pamu, pono e loaʻa ka wai e hoʻopaʻa ai i ka wai.ʻElua ʻano o nā sila wai: ʻo ka hoʻohana ʻana i ka wai puka o ka impeller pae mua, a ʻo kekahi e hoʻohana i ka wai waho.ʻO ka wai sila a pau i kaha ʻia ma ka Papa 2 e pili ana i ka wai sila wai waho, a ua hoʻohana ʻia ka wai sila wai o ka impeller pae mua e like me ka wai sila wai no ka poʻe ʻaʻole i kaha ʻia me ka wai sila wai.Pono pono ka paʻa o ka paʻi ʻana o ke sila aʻa, a he mea pono ke kahe ka wai i kēlā me kēia kulu.Ke ʻoi aku ka kiʻekiʻe o ka mahana o ka mea i lawe ʻia ma mua o 80 ° C, pono e hāʻawi ʻia ka wai hoʻoluʻu wai i ka wai hoʻoheheʻe wai a me ka shaft seal cooling chamber.3 kg / cubic centimeter, ʻo ke kaomi o ka wai sila wai he 0.5-1 kg / cubic centimeter kiʻekiʻe ma mua o ka lua o ka sila.ʻOkoʻa ke kūlana o ka paipu pipeline o ka sila wai a me ke keʻena hoʻoluʻu o ka sila shaft o nā ʻano pauma like ʻole.Hōʻike ʻia ke kūlana o ka paipu paipu ma ka ʻaoʻao axial ma ke kiʻi hoʻolālā pump.

3. Mekini kaulike

Hoʻokumu ʻia ka mīkini kaulike me ke apo kaulike, ka lima kaulike, ka disc balance a me ka pipeline kaulike, etc.

4. Hapai hapa

ʻO ka ʻaoʻao bearing ka mea nui i hui pū ʻia me kahi kino bearing a me kahi bearing.ʻElua mau ʻano o kēia ʻano o nā bearings: sliding bearings a me nā kahe kahe.ʻAʻohe o nā bearings e lawe i ka ikaika axial.I ka holo ʻana o ka paila, pono e hiki i ka ʻāpana rotor ke neʻe axially i loko o ka pahu pahu.ʻAʻole hiki ke hoʻohana ʻia nā bearings ball radial.Hōʻike ʻia nā bearings i hoʻohana ʻia e nā ʻano ʻano pauma ma ka Papa 1.

5. Pump sealing a me ka hooluolu

Hoʻopili ʻia ka ʻili hui o ka ʻāpana suction, ka ʻāpana waena, ka ʻāpana hoʻokuʻu a me ka vane alakaʻi i ka ʻāpana pūpū me ka molybdenum disulfide grease no ka hoʻopaʻa ʻana.

Hoʻopaʻa ʻia ka ʻāpana rotor a me ka ʻāpana paʻa e nā apo sealing, nā lima lima alakaʻi, nā mea hoʻopihapiha, a me nā mea ʻē aʻe. .Ke hoʻohana ʻia kēia ʻano hoʻohālike, pono ke kau pono ʻia ke kūlana o ke apo paʻi.E nānā i ka Papa 2 no ka māhele ʻana i nā apo paʻi a me nā apo o nā ʻano pauma like ʻole.
