Chaw Tsim Khoom thiab Chaw Muab Khoom Siv Expansion Joint (Roj Hmab Compensator) Zoo Tshaj Plaws

Kev Sib Koom Tes Nthuav Dav

Lub Expansion Joint feem ntau yog siv rau ntawm cov dredgers los txuas lub twj tso kua mis dredge thiab cov kav dej, thiab los txuas cov kav dej ntawm lub lawj. Vim yog qhov yooj ywm ntawm lub cev hose, nws tuaj yeem muab qee qhov kev nthuav dav thiab kev sib cog lus los them rau qhov sib txawv ntawm cov kav dej thiab pab txhawb kev teeb tsa thiab kev saib xyuas ntawm cov khoom siv. Lub Expansion Joint muaj qhov cuam tshuam zoo rau kev nqus dej thaum lub sijhawm ua haujlwm thiab ua lub luag haujlwm tiv thaiv rau cov khoom siv.

Lub Expansion Joint yog ib hom roj hmab uas luv luv thiab feem ntau tsis txog 1m. Nws tuaj yeem tsim los tiv taus ntau yam kev ntsuas siab. Lub Expansion Joints tuaj yeem tsim thiab ua kom tiv taus qhov siab tsis zoo, xws li "-0.1 MPa", thiab tiv taus qhov siab zoo, xws li "1.0 MPa", "2.5 MPa", thiab txawm tias tiv taus ob qho tib si qhov siab tsis zoo thiab qhov siab zoo, xws li "-0.1 MPa ~ 1.5 MPa", yog li Expansion Joint siv tau rau ntau yam kev mob siab.

Lub Pob Qij Txuas Ntxiv muaj cov hom hauv qab no: Lub Pob Qij Txuas Ntxiv nrog Lub Nipple Hlau, Lub Pob Qij Txuas Ntxiv nrog Lub Flange Sandwich thiab Lub Pob Qij Txuas Ntxiv nrog lub qhov txo qis.

Cov yam ntxwv

(1) Nrog ntau yam kev ntsuas siab, tsim nyog rau ob qho tib si tsis zoo thiab zoo siab.
(2) Kev ua haujlwm zoo heev
(3) Kev ywj pheej zoo
(4) Kev nqus dej zoo

Cov Kev Ntsuas Kev Txawj

(1) Qhov Loj Nominal Bore: 100 hli ~ 1300 hli
(2) Qhov Ntev ntawm Hose: 0.2 m ~ 1 m (kev kam rau siab: ± 1%)
(3) Kev Ua Haujlwm Siab: -0.1 MPa txog 3.0 MPa

Daim Ntawv Thov

Cov Pob Sib Txuas Lus (Expansion Joint) yog ib qho tseem ceeb rau cov kab ke tseem ceeb ntawm Cutter Suction Dredger (CSD) thiab Trailing Suction Hopper Dredger (TSHD), nws siv rau hauv cov kav dej dav hlau, cov kav dej thauj khoom hauv lub tank, cov kav dej pem hauv ntej thiab tom qab ntawm lub twj tso kua mis, thiab cov kav dej hauv lub lawj. Cov Pob Sib Txuas Lus (Expansion Joints) uas tsim los ntawm CDSR tau txais kev ntseeg siab los ntawm cov neeg siv hauv tsev thiab txawv teb chaws.

Yuav tsum tau xyuam xim rau qhov sib raug zoo ntawm qhov ntev ntawm Expansion Joint thiab qhov chaw rau kev teeb tsa, vim nws muaj feem cuam tshuam rau lub neej ua haujlwm ntawm cov khoom. Feem ntau qhov ntev ntawm Expansion Joint yog 0 ~ 5 hli luv dua qhov chaw uas nws tau teeb tsa, thiab qhov siab tshaj plaws ntawm kev teeb tsa yuav tsum tsis pub tshaj 10 hli rau Expansion Joint ntev (yuav luag 1m ntev). Yog tias qhov chaw teeb tsa loj dhau, Expansion Joint yuav ib txwm ncab thiab qhov no yuav ua rau nws cov qauv puas tsuaj.

CDSR Dredging Hoses ua raws li cov kev cai ntawm ISO 28017-2018 "Roj hmab hoses thiab hose assemblies, hlau lossis textile reinforced, rau dredging applications-Specification" nrog rau HG / T2490-2011
