ʻO ke alakaʻi koho ʻana i ka lau wili

1. E wehewehe i ke ʻano o ka hoʻohana ʻana

ʻO ke ʻano o ka hoʻohana ʻana i ka lau wili e hoʻoholo ai i kona hoʻolālā ʻana a me ke koho ʻana i nā mea hana, eia nā hiʻohiʻona maʻamau a me kā lākou mau koi:

Ka lawe ʻana i nā mea (e like me ka mīkini lawe wili): Hoʻohana ʻia no ka lawe ʻana i ka pauka, nā granules a i ʻole nā mea puʻupuʻu (e like me ka palaoa, ka lanahu, ka sima), e koi ana i ka pale ʻana i ka ʻaʻahu maikaʻi a me ka pitch like.

Ka hoʻoulu ʻana i ka wai (e like me ka propeller): Hoʻohana ʻia no nā moku a i ʻole nā lako wai, e koi ana i ka pololei kiʻekiʻe a me ka hana kaulike dynamic maikaʻi.

Ka hui ʻana (e like me ke kemika, ka meaʻai): Pono i ka pale ʻana i ka corrosion a me ka ʻili maʻemaʻe e pale aku i ka pili ʻana o nā mea.

Nā mīkini mahiʻai (e like me ka mea ʻohi): Pono i ka ikaika kiʻekiʻe, ka pale ʻana i ka ʻaʻahu, a me ka hoʻololi ʻana i nā kūlana hana paʻakikī.

Nā mea nui e koho ai:

E hoʻoholo i ke kaiapuni hana (e like me ka mahana, ka haʻahaʻa, ka corrosion).

E wehewehe i nā ʻano o nā mea a i ʻole nā mea waena (e like me ka nui o ka granule, ka viscosity, ka abrasiveness).

E hoʻoholo i ke ʻano o nā lako (e like me ka lawe mau ʻana a i ʻole ka hana intermittent).

2. E hoʻoholo i nā ʻāpana hoʻolālā koʻikoʻi

ʻO nā ʻāpana hoʻolālā o ka lau wili e pili pono i ka hana, a pono e hoʻoholo ʻia e like me nā pono noi:

ʻO ke anawaena waho a me ke anawaena o loko:

ʻO ke anawaena waho e pili ana i ka hiki ke lawe a i ʻole ka ikaika hoʻoulu, a ua kūlike pinepine ʻia me ka nui o nā lako.

Pono ke anawaena o loko e kūlike me ke anawaena o ke kumu e hōʻoia i ka paʻa o ka hoʻokomo ʻana.

Pitch:

ʻO ka nui o ka pitch e pili ana i ka pono o ka lawe ʻana a i ʻole ka thrust, hiki i ka pitch nui ke alakaʻi i ka paʻa, a ʻo ka liʻiliʻi e haʻahaʻa ka pono.

ʻO ka laulā pitch maʻamau: 0.5-2 mau manawa ke anawaena waho, hoʻoponopono ʻia e like me nā ʻano o nā mea a i ʻole ka wai.

Mānoanoa lau:

Pono ka mānoanoa e kaulike i ka ikaika a me ke kaumaha, kūpono nā lau lahilahi (2-6mm) no nā ukana māmā, a kūpono nā lau mānoanoa (6-20mm) no nā ukana kaumaha a i ʻole nā kaiapuni ʻaʻahu kiʻekiʻe.

Huina wili:

ʻO ka huina e pili ana i ke kahe ʻana o nā mea a i ʻole ka pono o ka thrust, a ua hoʻonui pinepine ʻia e ka helu ʻana i ka fluid dynamics (CFD) a i ʻole nā formula empirical.

Hoʻomau:

Nā lau wili hoʻomau: Kūpono no ka lawe ʻana i kahi lōʻihi, ʻoi aku ke kiʻekiʻe o ke kumukūʻai hana.

Nā lau wili segmented: Maʻalahi e hoʻokomo a mālama, kūpono no nā noi non-standard a i ʻole nā noi liʻiliʻi.

Nā mea nui e koho ai:

E hoʻohana i ka polokalamu CAD e hoʻohālike, a hui pū me ka finite element analysis (FEA) e hōʻoia i ka ikaika.

E nānā i nā kūlana ʻoihana (e like me ke kūlana CEMA o ka mīkini lawe) a i ʻole nā kikoʻī hoʻolālā lako.

3. Koho mea hana

Pono ke koho ʻana i nā mea hana e pili ana i ke kaiapuni hana a me ka waihona kālā:

ʻO ke kila kalapona maʻamau (e like me Q235, Q345):

Nā pōmaikaʻi: Haʻahaʻa ke kumukūʻai, maikaʻi ka hana.

Kūpono: Nā kaiapuni non-corrosive, e like me ka lawe ʻana i nā mea maloʻo.

ʻO ke kila kila (e like me 304, 316):

Nā pōmaikaʻi: Pale i ka corrosion, ʻili maʻemaʻe, kūpono i nā koi o ka meaʻai a i ʻole ke kemika.

Kūpono: Nā kaiapuni haʻahaʻa, acidic a me alkaline a i ʻole ka hana ʻana i ka meaʻai.

ʻO ke kila pale ʻaʻahu (e like me Hardox, NM400):

Nā pōmaikaʻi: ʻO ke kiʻekiʻe kiʻekiʻe, ka pale ʻana i ka ʻaʻahu ikaika.

Kūpono: ʻO nā hiʻohiʻona ʻaʻahu kiʻekiʻe e like me ka ore a me ka lanahu.

ʻO ke kila alloy a i ʻole nā mea hui:

Nā pōmaikaʻi: Pale i ka wela kiʻekiʻe a i ʻole ka corrosion kemika kūikawā.

Kūpono: Nā umu wela kiʻekiʻe, nā reactors kemika, a pēlā aku.

Lapaʻau ʻili:

E kāpīpī i kahi uhi pale ʻaʻahu (e like me ka ceramic, polyurethane) a i ʻole ka galvanizing e hoʻonui i ka lōʻihi.

Nā mea nui e koho ai:

E koho i ka paʻakikī e like me ka abrasiveness o nā mea (e like me ke kila pale ʻaʻahu me HRC>50).

E koho i ke kila kila a i ʻole nā mea uhi i nā kaiapuni corrosive.

E noʻonoʻo i ka hopena o ke kaumaha i ka ukana lako, hiki i nā mea pālahalaha kiʻekiʻe ke hōʻemi i ka hoʻohana ʻana i ka ikehu.

4. Koho i ke kaʻina hana hana

ʻO ke kaʻina hana hana e pili ana i ke kumukūʻai, ka pololei a me ka pono hana, a pono e koho ʻia e like me nā pono:

Hoʻokumu ʻia ka ʻōwili anu:

Nā pōmaikaʻi: ʻO ke kiʻekiʻe kiʻekiʻe, ʻili maʻemaʻe, kūpono no ka hana nui.

Kūpono: Nā lau pālahalaha hoʻomau (e like me ka mānoanoa <6mm).

Nā palena: ʻAʻole kūpono no nā pā mānoanoa a i ʻole nā ʻano paʻakikī.

ʻO ka ʻōwili wela/ka hana ʻana i ka mold:

Nā pōmaikaʻi: Kūpono no nā lau pā mānoanoa a i ʻole nā lau anawaena nui, hoʻololi i nā hoʻolālā non-standard.

Kūpono: Nā lako kaumaha a i ʻole nā lau i hana ʻia.

Nā palena: ʻO ka ʻili ʻino, pono i ka hana hou.

Welding segmented:

Nā pōmaikaʻi: ʻO ke kiʻekiʻe kiʻekiʻe, maʻalahi no ka lawe ʻana a me ka hui ʻana ma ka pūnaewele.

Kūpono: Nā lau liʻiliʻi a i ʻole nā lau non-standard.

Nā palena: ʻOi aku ka haʻahaʻa o ka ikaika o ka weld, pono e hoʻomalu pono i ka deformation.

Hana CNC:

Nā pōmaikaʻi: ʻO ke kiʻekiʻe kiʻekiʻe, kūpono no nā ʻano paʻakikī a i ʻole nā pūʻulu liʻiliʻi.

Kūpono: Nā propellers pololei kiʻekiʻe a i ʻole ka hoʻomohala prototype.

Nā palena: Kiʻekiʻe ke kumukūʻai, haʻahaʻa ka pono.

5. Nā koi hana a me ka maikaʻi

E hōʻoia i ka hoʻokō ʻana o nā lau wili i nā kūlana hana a me ka maikaʻi:

Pololei nui: ʻO ka pitch, ke anawaena waho, a me ka ʻokoʻa anawaena o loko e hoʻomalu ʻia i loko o ±1-2mm.

ʻO ka maikaʻi o ka ʻili: ʻAʻohe māwae, nā puka ea, ka ʻino Ra 3.2-12.5μm.

Kaulike Dynamic: Pono nā lako hana hoʻololi kiʻekiʻe e hana i nā hoʻokolohua kaulike dynamic e hōʻemi i ka haʻalulu.

ʻO ka maikaʻi o ka weld: Pono nā lau segmented e hele i ka ultrasonic a i ʻole ka nānā ʻana i ka X-ray o nā welds.

ʻImi mea: E hōʻoia i ka hana mea ma o ka spectral analysis a i ʻole ka hoʻāʻo ʻana i ka paʻakikī.

Nā mea nui e koho ai:

E koi i nā mea hoʻolako e hāʻawi i nā hōʻike hoʻokolohua maikaʻi (e like me ka nui, nā mea, nā welds).

Pono e hana ʻia nā hoʻokolohua kaulike dynamic a me ka luhi no nā noi wikiwiki a kaumaha paha.

6. Ka mālama ʻana i ke kumukūʻai a me ka waihona kālā

ʻO ke kumukūʻai mea: ʻO ke kila kalapona ka mea waiwai loa, ʻoi aku ke kiʻekiʻe o ke kila kila a me ke kila pale ʻaʻahu.

ʻO ke kumukūʻai hana: Haʻahaʻa ke kumukūʻai o ka hana nui ʻana i ka ʻōwili anu, ʻoi aku ke kiʻekiʻe o ke kumukūʻai o ka hana CNC a me ka paʻi 3D.

ʻO ke kumukūʻai mālama: Maʻalahi nā lau segmented e pani, e hōʻemi ana i nā kumukūʻai mālama.

ʻO ke kumukūʻai ola: Hiki i nā mea lōʻihi a me nā kaʻina hana kiʻekiʻe ke hōʻemi i nā kumukūʻai mālama a me ka hoʻololi ʻana i ka wā lōʻihi.

Nā mea nui e koho ai:

E kaulike i ka hoʻopukapuka mua a me nā kumukūʻai hoʻohana lōʻihi.

Hiki ke koho ʻia ka welding segmented no nā pūʻulu liʻiliʻi a i ʻole nā papahana manawaleʻa e hōʻemi i nā kumukūʻai.

E koho i ke kaʻina hana ʻōwili anu kiʻekiʻe no nā papahana nui.
