ʻO ka Hose Suction Maikaʻi Loa (Rubber Suction Hose / Dredging Hose) Mea Hana a me ka Mea Hoʻolako

Nā Paipu Omo

Hoʻopili nui ʻia nā Hose Suction ma ka lima kauō o ka Trailing Suction Hopper Dredger (TSHD) a i ʻole ke alapiʻi ʻokiʻoki o ka Cutter Suction Dredger (CSD). Ke hoʻohālikelike ʻia me nā hose hoʻokuʻu, hiki i nā hose omo ke kū i ke kaomi maikaʻi ʻole me ke kaomi maikaʻi, a hiki ke hana mau ma lalo o nā kūlana kūlou ikaika. He mau hose laholio koʻikoʻi lākou no nā dredgers.

ʻO nā hiʻohiʻona nui o ka Suction Hose he kūpaʻa maikaʻi i ka ʻaʻahu, ke kūpaʻa i ka wā, a me ka maʻalahi.

ʻO ka maʻamau, ʻo ke kaomi hana kiʻekiʻe loa o nā Hose Suction a hiki i ka -0.1 MPa, a ʻo ke kaomi hoʻāʻo he -0.08 MPa. Loaʻa pū nā Hose Suction me nā koi kūikawā a i ʻole i hoʻopilikino ʻia, e like me nā mea hiki ke kū i nā kaomi mai -0.1 MPa a i 0.5 MPa. He kūpono nā Hose Suction no nā mahana ambient mai -20℃ a i 50℃, a kūpono no ka lawe ʻana i nā hui o ka wai (a i ʻole ka wai kai), ka silt, ka lepo, ka pālolo a me ke one, e kū ana ma ke kaumaha kikoʻī mai 1.0 g/cm³ a i 2.0 g/cm³.

Ua kūlike nā hose omo CDSR me nā koi o ke kūlana International ISO28017-2018 a me ke kūlana o ke Kuhina ʻOihana Kemika o Kina HG/T2490-2011, a hiki nō hoʻi ke hoʻokō i nā koi hana huahana kiʻekiʻe a kūpono hoʻi mai nā mea kūʻai aku.

Wahi a nā kūlana hana like ʻole, ʻehā ʻano o nā Hose Suction: ʻO ka Hose Suction me ka Nipple Steel, ʻO ka Hose Suction me ka Sandwich Flange, ʻO ka Hose Suction Armored a me ka Segment Steel Cone Hose.

Hose omo me ka Nipple kila

He kūpaʻa maikaʻi ka CDSR Suction Hose me ka Steel Nipple i ke kapa komo, ka maʻalahi a me ke kūpaʻa tensile, kūpono no ke kūlana vacuum a me ke kaomi.

Hose omo me ka Sandwich Flange

He kūpaʻa maikaʻi ka CDSR Suction Hose me ka Sandwich Flange i ka ʻaʻahu ʻana, ke kūpaʻa ʻana i ka vacuum a me ka maʻalahi, a kūpono no nā noi me ka wahi hoʻonohonoho palena.

Hose Kono Kila ʻĀpana

Hoʻohana pinepine ʻia ka CDSR Segment Steel Cone Hose i ke alapiʻi ʻokiʻoki o Cutter Suction Dredger (CSD), kūpono no ka lawe ʻana i nā mea ʻoi a paʻakikī e like me ke koʻa, ke ʻiliʻili, ke one ʻoiʻoi, ka pōhaku i palaho ʻia, a pēlā aku.

Nā Hiʻohiʻona

(1) Kūkulu ʻia me nā cone kila kūpaʻa loa e like me ka ʻili hana.
(2) Hoʻohui kuhikuhi a me ka pilina.
(3) Kūlana paʻa a me ka hiki ke lawe.

Hoʻokō piha nā Hose Suction CDSR i nā koi o ISO 28017-2018 "Nā hose laholio a me nā ʻākoakoa hose, uea a i ʻole ka lole i hoʻoikaika ʻia, no nā noi dredging-Specification" a me HG/T2490-2011.
