Cov yam tseem ceeb uas yuav tsum paub ua ntej xaiv lub raj xa dej ntws

1. Nkag siab txog cov yam ntxwv ntawm cov khoom siv xa khoom

Qhov degree ntawm kev hnav ntawm cov hoses sib txawv heev nyob ntawm cov khoom siv:

Cov yeeb nkab uas ntab dej ib txwm muaj peev xwm thauj dej, dej hiav txwv, thiab cov av nkos, av nplaum, thiab xuab zeb sib xyaw;

Thaum thauj cov khoom siv hauv cov xwm txheej ua haujlwm hnyav xws li cov pob zeb coral thiab cov pob zeb uas tau hloov pauv, qhov twg cov khoom siv feem ntau yog lub kaum sab xis thiab tawv heev, lub hose uas muaj kev tiv thaiv kev hnav siab, xws lilubarmored floating hose nrogua tiav lawmlub nplhaib hlau uas tsis yooj yim hnavs, yuav tsum tau xaiv.

 

2. Txheeb xyuas qhov loj ntawm cov yeeb nkab: txoj kab uas hla thiab ntev

Qhov loj ntawm cov hose ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov dej ntws thiab kev sib raug zoo ntawm lub system:

Txoj kab uas hla sab hauv: Qhov ntau thiab tsawg yog 400mm–1200mm, uas yuav tsum phim lub twj tso kua mis thiab cov kav dej kom tsis txhob muaj kev poob dej lossis kev tsis sib xws ntawm lub siab.

Ntev: Qhov ntau thiab tsawg yog 6m ~ 11.8m. Nws yuav tsum tau xaiv kom raug raws li qhov chaw thiab qhov xav tau ntawm qhov chaw ua haujlwm. Ntev dhau los yog luv dhau yuav cuam tshuam rau kev ua haujlwm yooj ywm.

Txawm hais tias cov kav dej loj uas muaj txoj kab uas hla loj tuaj yeem ua rau kom ntws tau ntau ntxiv, tab sis kuj yuav tsum xav txog qhov yooj ywm thiab qhov hnyav.

 

3. Ua haujlwm siab thiab burs siab

Lub raj xa dej yuav tsum muaj peev xwm tiv taus qhov siab tshaj plaws ntawm lub kaw lus thiab muaj kev nyab xeeb txaus:

Kev ua haujlwm siab txheem: 1.0-4.0MPa (nyob ntawm seb muaj kev ua haujlwm tshwj xeeb li cas)

Lub zog tawg yuav tsum tsawg kawg yog 3 npaug ntawm lub zog ua haujlwm kom ntseeg tau tias muaj kev nyab xeeb

Yuav tsum tau xav txog qhov kev hloov pauv ntawm lub siab kom tiv thaiv kev puas tsuaj ntawm cov kav dej los ntawm kev siab siab ib ntus.

 

4. Kev yooj ywm thiab qhov tsawg kawg nkaus khoov vojvoog

Cov yeeb nkab uas ntab yuav tsum tau hloov kho rau cov nthwv dej, dej ntws thiab kev txav ntawm lub tshuab dredger, yog li kev ywj pheej yog qhov tseem ceeb heev:

Me me heevqhov khoov vojvoog yuav ua rau lub raj dej khoov lossis tawg.

Ib lub raj dej uas mos dhau yuav vau thaum muaj kev kub siab, cuam tshuam raukev thauj mus loskev ua haujlwm tau zoo.

 

5. Kev ntab dej

Tus ntablub tsho lojyog ua los ntawm cov khoom siv ua npuas ncauj PE kaw-cell thiab yuav tsum muaj cov yam ntxwv hauv qab no:

Kev ntab siab heev, nyob twj ywm thaum lub sijhawmua haujlwm.

Kev nqus dej tsawg kom tsis txhob poob vim yog kev nqus dej.

 

6. Kev tiv thaiv xeb ntawm cov khoom siv thiab kev hloov pauv ib puag ncig

Ib puag ncig hauv dej hiav txwv ua rau muaj kev xav tau ntau rau cov ntaub ntawv siv rau cov yeeb nkab:

Flanges thiab cov khoom siv txhawb nqa xav tau kev kho mob tiv thaiv corrosion

Cov khoom siv hose yuav tsum haum rau qhov kub thiab txias thiab ib puag ncig tshuaj lom neeg ntawm qhov chaw ua haujlwm.

 

7. Cov qauv ntawv pov thawj thiab kev xeem

Cov yeeb nkab CDSR dredgingua raws li cov qauv thoob ntiaj teb ISO28017-2018 "Cov roj hmab hoses thiab hose assemblies, hlau lossis textile reinforced, rau dredging daim ntawv thov - Specification" thiabSuav tebtus qauv HG/T2490-2011 "Cov roj hmab hoses thiab cov ntaub reinforced roj hmab hoses rau dredging engineering thiab Hose Assembly Specifications" thiab yog tsim thiab manufactured nyob rau hauv ib tug zoo system uas ua raws li ISO 9001. Tag nrho cov hoses tsim los ntawm CDSR undergoesnrujkev tswj xyuas zookom ntseeg tau tias zoo. Okoj cov khoom kuj tuaj yeem hloov kho kom tau raws li cov neeg siv khoom xav tau.
