ʻOi aku ka maikaʻi o ka Expansion Joint (Rubber Compensator) mea hana a me ka mea hoʻolako |CDSR

Hui Hoonui

Hoʻohana nui ʻia ka Expansion Joint ma nā dredgers e hoʻopili i ka dredge pump a me ka pipeline, a e hoʻopili i nā pipelines ma ka deck.Ma muli o ka maʻalahi o ke kino hose, hiki iā ia ke hāʻawi i kahi nui o ka hoʻonui a me ka hoʻopaʻa ʻana e hoʻopaʻi i ke āpau ma waena o nā paipu a hoʻomaʻamaʻa i ka hoʻonohonoho ʻana a me ka mālama ʻana i nā mea hana.Loaʻa i ka Expansion Joint kahi hopena haʻalulu maikaʻi i ka wā o ka hana a hoʻokani i kahi hana pale no nā mea hana.

ʻO ka Expansion Joint he ʻano puʻupuʻu lāʻau me ka lōʻihi pōkole a ma lalo o 1m ka lōʻihi.Hiki ke hoʻolālā ʻia no ka pale ʻana i kahi ākea o nā helu kaomi.Hiki ke hoʻolālā ʻia a kūkulu ʻia nā hui hoʻonui no ke kū ʻana i ke kaomi ʻino, e like me "-0.1 MPa", a no ka pale ʻana i nā kaomi maikaʻi, e like me "1.0 MPa", "2.5 MPa", a hiki i ka pale ʻana i ka puʻe maikaʻi ʻole a me ke kaomi maikaʻi. e like me "-0.1 MPa ~ 1.5 MPa", no laila e pili ana ka Expansion Joint i nā kūlana paʻi like ʻole.

Aia nā ʻano o ka Expansion Joint: Expansion Joint me Steel Nipple, Expansion Joint me Sandwich Flange a me Expansion Joint me ka hoʻohaʻahaʻa ʻana i ka lua.

Nā hiʻohiʻona

(1) Me ka laulā ākea o ka helu kaomi, kūpono no nā kūlana ʻino a maikaʻi.
(2) Kūleʻa abrasion maikaʻi loa
(3) Elasticity maikaʻi
(4) Maikaʻi ka haʻalulu

Nā ʻāpana ʻenehana

(1) Nominal Bore Size: 100 mm ~ 1300 mm
(2) Ka lōʻihi o ka paipu: 0.2 m ~ 1 m (hoʻomanawanui: ±1%)
(3) Paʻi Hana: -0.1 MPa i ka 3.0 MPa

Palapala noi

He mea pono ka Expansion Joint no nā ʻōnaehana koʻikoʻi o ka Cutter Suction Dredger (CSD) a me Trailing Suction Hopper Dredger (TSHD), ua hoʻohana ʻia i loko o ka ʻōnaehana hose wai wai, ʻōnaehana hoʻoili pahu pahu, ka paipu mua a hope o ka paila, a ka ʻōnaehana paipu deck.Ua hilinaʻi nui ʻia nā Hui Hoʻonui i hana ʻia e CDSR e nā mea hoʻohana kūloko a me nā haole.

Pono e hoʻolohe i ka pilina ma waena o ka lōʻihi o ka Expansion Joint a me ka wahi no ka hoʻonohonoho ʻana, no ka mea e pili ana i ke ola lawelawe o ka huahana.ʻO ka maʻamau ka lōʻihi o ka Expansion Joint ʻo 0 ~ 5mm ka pōkole ma mua o ka wahi i hoʻokomo ʻia ai, a ʻaʻole ʻoi aku ka nui o ka hoʻokomo ʻana i ka 10mm no ka Hui Hoʻonui lōʻihi (kokoke i 1m ka lōʻihi).Inā ʻoi aku ka nui o ka ʻae ʻana o ka hoʻokomo ʻana, e hohola mau ʻia ka Expansion Joint a hiki i kēia ke hōʻino i kona ʻano.

Hoʻokō piha ʻo CDSR Dredging Hoses i nā koi o ISO 28017-2018 "Rubber hoses a me nā hui hose, wire a textile i hoʻoikaika ʻia, no ka dredging applications-Specification" a me HG/T2490-2011
