Thaum cov neeg feem coob hnov 'cov khoom siv hauv hiav txwv', lawv pom ib qho ci ntsa iab stainless hlau cleat lossis lub lawj haum. Qhov ntawd yog thawj qhov kev xav tsis zoo. Hauv kev muaj tiag, nws yog lub ntiaj teb ntawm cov khoom siv uas cov khoom siv tsis ua haujlwm tsis yog qhov kev xaiv, thiab lub ntsiab lus ntawm 'corrosion-resistant' tau raug sim nyob rau hauv txoj kev av-raws li engineers tsis tshua xav txog. Cov dej ntsev tsis yog xeb hlau xwb; nws tsim ib tug phem electrochemical ib puag ncig uas muaj peev xwm tig ib tug me me casting flaw mus rau ib tug kev puas tsuaj tsis ua hauj lwm. Kuv tau pom ntau txoj haujlwm uas cov khoom siv kho vajtse yog qhov kev xav tom qab, xaiv los ntawm cov ntawv teev npe raws li tus nqi thiab lub cim tsis meej 'marine-qib', ua rau kim hu rov qab. Qhov tseeb yog, qhia txog cov khoom siv hauv hiav txwv yog kev qhuab qhia hauv nws tus kheej, ntsuas qhov sib npaug ntawm cov khoom siv hlau, cov txheej txheem tsim khoom, thiab kev nkag siab tob txog qhov tseeb ntawm lub voj voog - tsis yog cov theoretical xwb.
Lub hauv paus tsis nkag siab: Khoom siv vs
Txhua tus tsom mus rau 316 stainless. Nws yog qhov mus-mus. Tab sis kev qhia 316 tsuas yog kab pib xwb, tsis yog qhov kawg. Kuv tau txais qhov chaw sau npe 316 uas ua tsis tiav pitting xeem nyob rau hauv lub lis piam nyob rau hauv ib tug simulated splash cheeb tsam. Qhov teeb meem? Cov marine hardware yog peev cam khwb cia, tab sis lub foundry tus txheej txheem tswj tau tawm-tej zaum lub ncuav kub, los yog cov khoom pwm qhia impurities. Daim ntawv pov thawj alloy zoo li zoo meej, tab sis lub microstructure qhia ib zaj dab neeg sib txawv. Qhov no yog qhov twg ntau xyoo ntawm kev paub txog kev tsim, zoo li qhov koj pom nrog tus kws tshaj lij xws li Qingdao Qiangsenyuan Technology Co., Ltd. (QSY), qhov tseem ceeb. Lawv tau nyob hauv casting thiab machining rau ntau tshaj 30 xyoo. Cov keeb kwm ntawd tsis yog kev lag luam xwb; nws txhais tau tias lawv tau ntsib thiab daws tau cov teeb meem tshwj xeeb thermal stress uas tsim cov ntsiab lus tsis muaj zog hauv a marine hardware tiv thaiv zoo li lub cev los ntawm lub cev.
Nws yog kev sib xyaw ntawm plhaub pwm casting rau qee qhov geometry thiab peev casting rau lwm tus uas ua rau qhov sib txawv. Lub complex, nyias-walled haum rau hydraulic system? Tej zaum peev casting rau qhov tseeb qhov tseeb. Lub qhov muag loj dua, qhov muag ntawm lub qhov muag rau tus pas nrig? Plhaub pwm tej zaum yuav muaj zog dua thiab raug nqi. QSY qhov ntau ntawm cov txheej txheem no yog qhov ua tau zoo. Lawv tsis raug kaw rau hauv ib qho txheej txheem, uas tso cai rau kev pom zoo raws li ib feem ntawm txoj haujlwm, tsis yog lawv cov cuab yeej muaj peev xwm. Koj tuaj yeem tshawb xyuas lawv txoj hauv kev ntawm lawv qhov chaw, https://www.tsingtaocnc.com.
Lub machining tiav yog lwm qhov tseem ceeb, tsis pom kev. Ib tug ntxhib machined nto ntawm ib tug ncej foob cheeb tsam yog ib tug guaranteed los ntawm txoj kev. Nws tsis yog hais txog Ra tus nqi; nws yog hais txog cov kev taw qhia ntawm cov cuab yeej cov cim, cov ntug tawg, thiab tsis txhob muaj cov micro-fractures los ntawm txhoj puab heev machining. Qhov no yog qhov uas lawv CNC machining kev koom ua ke los hauv. Muaj casting thiab machining nyob rau hauv ib lub ru tsev tsis yog rau logistics xwb; nws tso cai rau pab pawg machining kom nkag siab txog qhov casting cov nplej ntws thiab muaj peev xwm nyuaj me ntsis, hloov kho lawv cov cuab yeej txoj hauv kev. Ib feem tuaj yeem muab pov tseg zoo kawg nkaus tab sis puas tsuaj hauv cov kauj ruam kawg machining yog tias cov pab pawg tsis sib haum.
Tiag tiag-Lub Ntiaj Teb Failure: Zaj Dab Neeg ntawm Sheared Bollard
Kuv nco qab txog qhov project retrofit ntawm lub nkoj ua haujlwm nruab nrab. Tus neeg siv xav hloov kho lub nraub qaum bollard. Cov duab kos tau hu ua lub zog siab qis-alloy steel, kub-dip galvanized. Qhov seem ntsia loj heev, xav tias khov. Nws dhau nws qhov kev xeem thauj khoom - qhov zoo li qub rub mus rau 150% ntawm kev ua haujlwm. Rau lub hlis tom qab, nws tau tshem tawm ntawm lub hauv paus thaum lub sij hawm ib txwm mooring ua hauj lwm nyob rau hauv lub hiav txwv nram qab no. Tsis muaj overload tswb. Kev tshawb nrhiav taw qhia rau kev qaug zog. Lub voj voog thauj khoom los ntawm lub nkoj tsis tu ncua, me ntsis yawing ntawm qhov chaw nres nkoj, ua ke nrog lub zog ntawm txoj kab mooring, tsim kev ntxhov siab ntau qhov tsim tsis tau suav rau. Lub galvanizing, thaum zoo rau kev txhim kho corrosion, tuaj yeem npog lossis txawm ua rau hydrogen embrittlement yog tias tsis ua tiav.
Qhov no yog qhov chaw xaiv cov khoom tau txais nuanced. Puas yog duplex stainless hlau tau zoo dua? Tejzaum. Tab sis tus nqi yog txwv tsis pub rau tus neeg siv khoom. Ib qho kev daws teeb meem zoo dua tuaj yeem yog qhov sib txawv ntawm cov qauv tsim nrog lub kaum sab xis sab hauv (tsis yog sab nraud xwb) thiab hloov mus rau cov khoom siv qaug zog ntau dua li cov hlau quenched thiab tempered, txawm tias nws yuav tsum tau siv cov xim nruj dua es tsis txhob galvanizing. Nws yog qhov ua tsis tiav hauv kev xav-pom lub bollard ua ib qho kev sib cais, tsis yog ib feem ntawm cov saw hlau dynamic.
Qhov kev paub no cuam tshuam ncaj qha rau tus nqi ntawm lub chaw tsim khoom cov khoom siv ntau yam. Ib lub tuam txhab uas tsuas yog ua haujlwm nrog cov qib stainless hlau yuav tau thawb rau 316, uas yuav ua tsis ncaj ncees rau daim ntawv thov qaug zog no. Ib tug khub zoo li QSY, teev tshwj xeeb alloys nrog rau cov nickel-raws li alloys, muaj kev paub hauv paus kom tsawg kawg muaj kev sib tham txog lwm txoj hauv kev. Tej zaum lawv yuav tsis yog tus kws tsim qauv tub rog, tab sis tus khub tsim khoom zoo yuav tsum nug cov lus nug txog kev pabcuam ib puag ncig thaum lawv pom daim duab kos rau ib qho tseem ceeb ntawm cov kabmob.
Dab ntxwg nyoog nyob rau hauv cov ntsiab lus: Fasteners thiab Compatibility
Tsis muaj dab tsi nthuav tawm cov neeg pluag marine hardware specification ceev tshaj fasteners. Kev sib xyaw hlau yog qhov yuam kev classic. Siv silicon bronze bolts kom ruaj 316 stainless hlau lawj phaj? Koj tab tom thov rau galvanic corrosion. Cov tooj liab yuav txi nws tus kheej, thiab sai sai. Txoj cai yog yooj yim: phim los yog ua tib zoo cais. Tab sis txawm nyob rau hauv stainless, muaj cov ntxiab.
