Inhlanganisela Engcono Kakhulu Yokunweba (Isinxephezelo Senjoloba) Umkhiqizi Nomhlinzeki |I-CDSR

Ukunwetshwa Okuhlangene

I-Expansion Joint isetshenziswa kakhulu kuma-dredgers ekuxhumeni iphampu ye-dredge kanye nepayipi, kanye nokuxhuma amapayipi kumpheme.Ngenxa yokuguquguquka komzimba we-hose, inganikeza inani elithile lokunwetshwa nokufinyela ukuze kunxeshezelwe igebe phakathi kwamapayipi futhi kube lula ukufakwa nokugcinwa kwezinto zokusebenza.I-Expansion Joint inomphumela omuhle wokumunca ukushaqeka ngesikhathi sokusebenza futhi idlala indima yokuvikela okokusebenza.

I-Expansion Joint iwuhlobo lwepayipi lerabha elinobude obufushane futhi ngokuvamile lingaphansi kwe-1m ngobude.Ingaklanywa ukuthi imelane nohlu olubanzi lwezilinganiso zengcindezi.Amalunga Okwandisa angaklanywa futhi akhelwe ukumelana nengcindezi engemihle, njengokuthi "-0.1 MPa", futhi amelane nezingcindezi ezinhle, ezinjengokuthi "1.0 MPa", "2.5 MPa", ngisho nokumelana nakho kokubili ingcindezi engemihle nokucindezela okuhle, okunjalo njengokuthi "-0.1 MPa ~ 1.5 MPa", ngaleyo ndlela I-Expansion Joint iyasebenza ezimeni zengcindezi ezihlukene.

I-Expansion Joint inezinhlobo ezilandelayo: I-Expansion Joint Ngengono Yensimbi, I-Expansion Joint nge-Sandwich Flange kanye ne-Expansion Joint nge-bore enciphisa.

Izici

(1) Ngebanga elibanzi lokulinganisa ingcindezi, elifanele kokubili izimo zengcindezi engemihle kanye nenhle.
(2) Ukumelana okuhle nokuhunyazwa
(3) Ukunwebeka okuhle
(4) Ukumuncwa okuhle kokushaqeka

Imingcele Yezobuchwepheshe

(1) Usayizi Wokubhoboza Okuzisholo: 100 mm ~ 1300 mm
(2) Ubude bepayipi: 0.2 m ~ 1 m (ukubekezelela: ±1%)
(3) Ingcindezi Yokusebenza: -0.1 MPa kuya ku-3.0 MPa

Isicelo

I-Expansion Joint iyingxenye edingekayo yezinhlelo ezibalulekile ze-Cutter Suction Dredger(CSD) kanye ne-Trailing Suction Hopper Dredger(TSHD), isetshenziswa ohlelweni lwepayipi lamanzi ejethi, uhlelo lwamapayipi okulayisha ithangi, ipayipi langaphambili nangemuva lephampu, futhi uhlelo lwamapayipi edekhi.I-Expansion Joints ekhiqizwe yi-CDSR ithenjwe ngokujulile ngabasebenzisi basekhaya nabangaphandle.

Kuyadingeka ukunaka ubudlelwano phakathi kobude be-Expansion Joint kanye nesikhala sokufakwa, njengoba kuhlobene nempilo yesevisi yomkhiqizo.Ngokuvamile ubude beJoyinti Yokunweba bufushane ngo-0~5mm kunendawo lapho ifakwe khona, futhi imvume yokufaka ephezulu akumele yeqe u-10mm ngeJoyinti Eyengeziwe Yokunweba (cishe i-1m ubude).Uma ngabe imvume yokufaka inkulu kakhulu, i-Expansion Joint izohlale yeluliwe futhi lokhu kungase konakalise isakhiwo sayo.

Ama-CDSR Dredging Hoses ahambisana ngokugcwele nezidingo ze-ISO 28017-2018 "Amapayipi erabha ne-hose assemblies, izintambo noma izindwangu eziqinisiwe, zokwehliswa kwezicelo-Ukucaciswa" kanye ne-HG/T2490-2011
