Kev ntxhov siab corrosion tawg yog yooj yim tsim ntawm cov ntiv taw vuam
Qhov kev ntxhov siab ntawm cov pob qij txha docking feem ntau yog tshwm sim los ntawm qhov siab ntawm qhov vuam. Cov pob qij txha welded ntawm lub connector yog qhov kev ntxhov siab tshaj plaws ntawm lawv cov ntiv taw welded.
Qhov loj ntawm qhov kev ntxhov siab coefficient nyob ntawm qhov siab ntawm vuam seam residue, lub kaum sab xis θ ntawm vuam ntiv taw, thiab lub kaum sab xis R. Qhov siab ntawm vuam seams nce, thiab lub kaum sab xis θ nce, thiab R tus nqi txo. , uas yuav ua rau kom cov concentration coefficient ntawm kev ntxhov siab.
Qhov siab dua qhov siab ntawm qhov vuam, qhov hnyav dua qhov concentration ntawm kev ntxhov siab, thiab kev siv ntawm cov vuam sib txuas yuav raug txo. Tom qab vuam, qhov seem qhov siab yog flattened. Tsuav nws tsis qis dua li cov khoom siv niam, txo qis kev ntxhov siab, qee zaum nws tuaj yeem ua rau muaj kev sib koom ua ke ntawm kev sib txuas.
Qhov seem welding seam yog siab, uas yog tsis conducive rau anticorrosive
Yog tias koj siv epoxy resin iav daim ntaub los tiv thaiv corrosion, qhov seem vuam seams yog siab, uas yuav ua rau nws nyuaj rau vuam ntiv taw. Nyob rau tib lub sijhawm, qhov siab dua qhov vuam, lub thicker lub anti-corrosion txheej yuav tsum thickened. Vim hais tias cov thickness ntawm cov txheej txheem los tiv thaiv corrosion yog xam raws li lub vertex ntawm vuam seams sab nraum tus qauv, qhov no ua rau tus nqi ntawm anticorrosion.
Thaum cov kauv faus arc vuam, sab nraud vuam seam ntawm "ntses ridge" yog feem ntau ua rau, uas yog qhov nyuaj dua los xyuas kom meej qhov zoo ntawm anticorrosion. Yog li ntawd, nws tseem yog ib qho tseem ceeb uas yuav tau kho lub spatial txoj hauj lwm thiab vuam specification ntawm lub vuam taub hau kom txo los yog tshem tawm cov txheej vuam seam ntawm "ntses ridge".
Qhov seem welding seam tseem siab, uas cuam tshuam rau lub raj zoo tom qab lub cheeb ntawm cov dej siab
Thaum qhov ncaj seam faus arc welded yeeb nkab yog nthuav dav hauv cov dej siab, cov yeeb nkab steel yog qhwv los ntawm sab laug thiab sab xis nrog tib qhov loj ntawm lub puab kab noj hniav thiab cov yeeb nkab steel txoj kab uas hla. Yog li ntawd, qhov seem ntawm qhov siab ntawm cov weld loj dhau lawm, thiab cov kev ntxhov siab shear raug kev txom nyem los ntawm cov welded seam thaum lub sij hawm txoj kab uas hla yog loj, thiab qhov tshwm sim "me me ncaj" yog nquag tshwm sim ntawm ob sab ntawm lub vuam.
Txawm li cas los xij, kev paub dhau los ua pov thawj tias thaum qhov siab ntawm sab nraud yog tswj hwm ntawm 2 hli, qhov tshwm sim "sab me me" yuav tsis tshwm sim thaum lub qhov dej siab ntawm txoj kab uas hla tau nthuav dav, thiab lub raj zoo yuav tsis cuam tshuam. Qhov no yog vim qhov seem ntawm qhov siab ntawm sab nraud yog me me, thiab qhov kev nyuab siab shear kuj me me nyob rau hauv qhov sib koom ua ke. Tsuav qhov kev ntxhov siab no nyob rau hauv qhov elastic deformation ntau yam, tom qab uninstalling, lub raj yuav rov qab los.
Internal vuam seams yog siab, thiab lub zog poob ntawm lub thauj nruab nrab nce
Yog hais tias qhov chaw ntawm lub puab nto ntawm lub faus arc vuam yeeb nkab tsis kho nrog txheej, qhov seem ntawm qhov siab ntawm cov weld sab hauv yog loj, thiab kev sib txhuam tsis kam ntawm qhov nruab nrab conveying kuj loj, uas yuav ua rau kom lub zog noj ntawm lub conveying. cov kav dej.
