Umvelisi kunye noMboneleli weJoint yoKwandisa eBalaseleyo (iRubber Compensator)

Indibano Yokwandisa

I-Expansion Joint isetyenziswa kakhulu kwi-dredgers ukudibanisa i-dredge pump kunye ne-pipeline, kunye nokudibanisa iipayipi kwi-deck. Ngenxa yokuguquguquka komzimba we-hose, inokubonelela ngokwandiswa kunye nokucutheka okuthile ukuvala umsantsa phakathi kweepayipi kunye nokwenza kube lula ukufakelwa kunye nokugcinwa kwezixhobo. I-Expansion Joint inefuthe elihle lokufunxa ukutshayiswa ngexesha lokusebenza kwaye idlala indima yokukhusela izixhobo.

I-Expansion Joint luhlobo lwepayipi yerabha enobude obufutshane kwaye ngokubanzi ingaphantsi kwe-1m ubude. Ingayilwa ukuze imelane noluhlu olubanzi lwemilinganiselo yoxinzelelo. Ii-Expansion Joints zinokuyilwa kwaye zakhiwe ukuze zimelane noxinzelelo olubi, olufana ne-"-0.1 MPa", kunye nokumelana noxinzelelo oluhle, olufana ne-"1.0 MPa", "2.5 MPa", kunye nokumelana noxinzelelo olubi kunye noxinzelelo oluhle, olufana ne-"-0.1 MPa ~ 1.5 MPa", ngoko ke i-Expansion Joint isebenza kwiimeko ezahlukeneyo zoxinzelelo.

I-Expansion Joint ineentlobo ezilandelayo: I-Expansion Joint eneNgqondo yeNsimbi, i-Expansion Joint ene-Sandwich Flange kunye ne-Expansion Joint ene-reducing bore.

Iimbonakalo

(1) Ngoluhlu olubanzi lovavanyo loxinzelelo, olufanele zombini iimeko zoxinzelelo ezimbi nezilungileyo.
(2) Ukumelana okuhle kakhulu nokurhawuzelelwa
(3) Ukuthamba okuhle
(4) Ukufunxa kakuhle uloyiko

Iiparameters zobugcisa

(1) Ubungakanani beBore eqhelekileyo: 100 mm ~ 1300 mm
(2) Ubude beHose: 0.2 m ~ 1 m (ukunyamezelana: ±1%)
(3) Uxinzelelo Lokusebenza: -0.1 MPa ukuya kwi-3.0 MPa

Isicelo

I-Expansion Joint yinxalenye ebalulekileyo kwiinkqubo ezibalulekileyo ze-Cutter Suction Dredger enkulu (CSD) kunye ne-Trailing Suction Hopper Dredger (TSHD), isetyenziswa kwinkqubo yepayipi yamanzi yejet, inkqubo yepayipi yokulayisha itanki, umbhobho wangaphambili nowangasemva wepompo, kunye nenkqubo yepayipi yedekhi. I-Expansion Joints eyenziwe yi-CDSR ithembeke kakhulu ngabasebenzisi basekhaya nabangaphandle.

Kuyimfuneko ukuqaphela ubudlelwane phakathi kobude be-Expansion Joint kunye nendawo yokufakela, njengoko inxulumene nobomi benkonzo yemveliso. Ngokwesiqhelo ubude be-Expansion Joint bufutshane nge-0~5mm kunesithuba apho ifakelwe khona, kwaye indawo ephezulu yokufaka ayizukudlula i-10mm kwi-Expansion Joint ende (phantse ibe yi-1m ubude). Ukuba indawo yokufaka inkulu kakhulu, i-Expansion Joint iya kuhlala yoluliwe kwaye oku kunokonakalisa isakhiwo sayo.

Iipayipi zokuDreda zeCDSR zihambelana ngokupheleleyo neemfuno ze-ISO 28017-2018 "Iipayipi zerabha kunye neendibano zeepayipi, ucingo okanye ilaphu eliqinisiweyo, zokusetyenziswa kwezicelo zokuDreda" kunye ne-HG/T2490-2011
