4U2U ntsia liaj qhov rooj phaj specs rau kev siv? 

Koj paub, thaum ib tug neeg nug txog 4U2U bolt phaj specs, tshwj xeeb tshaj yog rau cov khoom siv hnyav hnyav, kuv thawj qhov kev xav yog kom meej: peb puas tham txog tib yam? Hauv kuv qhov kev paub dhau los, qhov kev sib txuas ntawm cov lej - 4U2U - tsis yog ASTM lossis ISO tus qauv uas koj yuav pom tau kos rau ntawm daim ntawv luam. Nws yog ntau ntawm ib qho kev sab hauv, qhov project tshwj xeeb, lossis cov khoom siv luv luv. Kuv tau pom nws tshwm sim hauv RFQs los ntawm qee cov haujlwm, xws li cov tshuab hnyav hnyav lossis kev txhawb nqa tshwj xeeb. Nws feem ntau hais txog ib qho kev teeb tsa tshwj xeeb: a bolt phaj yuav tsim los rau M42 los yog zoo sib xws loj-inch thauj tog rau nkoj bolts, nrog ib tug tuab thiab lub qhov qauv kom phim ib tug 4U2U sib dhos daim duab. Qhov tsis meej pem pib thaum tib neeg kho nws zoo li tus lej xov tooj thoob ntiaj teb. Tsis yog. Kev sib tham tiag tiag yog hais txog kev txiav txim siab dab tsi daim ntawv lo qhia txog cov khoom siv, thauj khoom, thiab haum.

Qhov Tseeb Tom Qab Txoj Cai: Cov Khoom Siv thiab Qhov Tseem Ceeb

Yog li, dab tsi feem ntau yog faus rau hauv 4U2U spec? Los ntawm cov haujlwm uas kuv tau ua, nws feem ntau taw qhia rau lub phaj tuab, lub zog siab. Peb feem ntau saib ASTM A36 lossis, feem ntau rau cov kabmob hnyav, ASTM A572 Qib 50 steel. U yuav qhia txog chav tsev lossis ib pab pawg sib dhos tshwj xeeb. Lub 4 thiab 2 tuaj yeem cuam tshuam nrog lub voj voog qhov ntev lossis phaj tuab hauv centimeters-Kuv tau pom daim hlau nyob ib ncig ntawm 40mm tuab sau rau hauv cov lej zoo sib xws. Qhov tseem ceeb tshaj plaws yog qhov qauv ntawm lub qhov taub: qhov loj, qhov sib nrug, ntug nrug. Rau kev lag luam siv, lub qhov taub yog feem ntau 2-3 hli loj dua lub ntsia liaj qhov rooj shank rau kev sib haum xeeb kam rau ua. Yog hais tias nws yog rau lub hauv paus thauj tog rau nkoj, koj kuj tseem saib lub tes tsho los yog ntxhua khaub ncaws. Kuv nco qab txog qhov project rau lub hauv paus compressor qhov twg 4U2U phaj hu ua 40mm thickness, 450mm square, nrog plaub 45mm qhov ntawm lub voj voog 350mm. Daim duab tsis meej, tab sis qhov kev ntxhov siab calcs xav tau cov khoom siv qib 50.

Qhov twg tej yam tsis zoo yog thaum kev yuav khoom kho cov cai raws li txoj moo zoo. Kuv ib zaug muaj ib pawg ntawm daim hlau xa tuaj uas phim cov tuab thiab ntxhib loj, tab sis tus neeg muag khoom tau siv cov hlau pheej yig dua, qis-yield-lub zog, piv txwv li phaj phaj. Qhov haum yog zoo, tab sis thaum lub sij hawm kuaj load, peb pom hais txog deformation. Zaj lus qhia? Daim ntawv cim alphanumeric tsuas yog tus taw tes xwb. Koj yuav tsum hais txog lub hauv paus ntsiab lus ntawm cov khoom siv thiab cov khoom siv. Yog tias daim duab tsis sau lawv, koj yuav tsum thawb rov qab kom pom tseeb. Tsis txhob xav tias.

Qhov no yog qhov chaw ua haujlwm nrog cov chaw tsim khoom uas tau txais cov ntsiab lus kev lag luam yog qhov tseem ceeb. Ib qhov chaw zoo li HANDAN ZITAI FREWER RAUG UA MOV., Ltd. (https://www.zitaifasteners.com), raws li nyob rau hauv Tuam Tshoj tus qauv loj ib feem ntau lawm puag nyob rau hauv Yongnian, Handan, feem ntau muaj lub peev xwm los lis cov semi-kev cai, high-spec daim hlau. Lawv qhov sib thooj rau txoj kev thauj loj txhais tau hais tias lawv tau teeb tsa rau kev thauj khoom loj ntawm cov khoom hnyav. Qhov tseem ceeb yog muab rau lawv tsis yog nrog 4U2U daim ntawv lo, tab sis nrog tag nrho cov pob khoom: cov khoom siv qib, hardness, kev tso cai kam rau ua (tshwj xeeb tshaj yog rau qhov chaw qhov chaw, uas yog ib qho tseem ceeb rau ntau txoj hlua khi), thiab ib qho yuav tsum tau ua ntej tho lossis chamfering.

Common Pitfalls hauv Fabrication thiab Fit-Up

Txawm hais tias muaj qhov tseeb specs, fabrication tuaj yeem qhia txog teeb meem. Rau cov phaj tuab no, thermal txiav thiab drilling tuaj yeem cuam tshuam cov khoom siv nyob ib puag ncig lub qhov. Kuv ib txwm hais rau cov lus hais los ntawm lub khw. Puas yog lawv txiav plasma, laser txiav, lossis dej-dhau qhov profile? Rau qhov, lawv puas tau drilled, xuas nrig ntaus (tsis zoo li 40mm), los yog dhuav? Punching tsim ib qho chaw ua haujlwm hnyav; drilling xav tau kev pub thiab ceev kom tsis txhob tawv. Rau 4U2U hom phaj destined coj dynamic loads, tej zaum koj yuav tsum tau qhia kom meej lub qhov tiav-reaming tej zaum yuav tsim nyog rau meej bolt haum.

Lwm qhov kev mob taub hau yog flatness. Lub phaj tuab no tuaj yeem muaj kev ntxhov siab sab hauv los ntawm dov. Yog tias nws tsis muaj kev ntxhov siab los yog ua haujlwm zoo, nws tuaj yeem ua rau tom qab lub qhov raug txiav. Kuv tau pom ib lub phaj zoo nkauj uas tsis tuaj yeem zaum ntawm lub txaj txaj txaj vim tias nws muaj lub ntsej muag maj mam. Tam sim no, peb feem ntau hais kom meej meej qhov kev zam rau tag nrho saum npoo, tsis yog cov npoo. Nws ntxiv tus nqi, tab sis nws tiv thaiv cov sij hawm kho kev sib tsoo ntawm qhov chaw.

Tom qab ntawd muaj qhov haum nrog cov bolts lawv tus kheej. Lub phaj 4U2U feem ntau qhia txog kev siv cov hex bolts hnyav, tej zaum txawm tias thauj tog rau nkoj rods. Lub qhov tshem tawm yuav tsum tso cai rau me me misalignment tab sis tsis loj heev uas lub tshuab ntxhua khaub ncaws tsis npog nws. Peb kawm qhov no txoj kev nyuaj ntawm kev txhawb nqa conveyor. Cov qhov tau drilled 5 hli loj dua rau kev txhim kho yooj yim dua, tab sis nyob rau hauv kev co, cov bolts pib oval lub qhov. Qhov kev kho yog rau nruab kev cai loj loj washers, uas yog ib tug npau suav phem teb. Tus spec yuav tsum nruj tswj lub qhov-rau-bolt kev sib raug zoo.

Case hauv Point: Ib Gearbox Mounting Retrofit

Cia kuv muab ib qho piv txwv rau koj. Peb tau retrofitting lub loj gearbox rau hauv pem teb zeb uas twb muaj lawm. Qhov qub mounting siv 3U1U phaj (saib, ntau ntawm cov npe sab hauv). Lub gearbox tshiab yuav tsum muaj 4U2U interface. Qhov kev sib tw tsis yog ua lub phaj tshiab xwb; nws tau ua kom tus qauv bolt tshiab tuaj yeem hloov mus rau hauv lub hauv paus pob zeb uas twb muaj lawm. Lub 4U2U spec los ntawm lub gearbox OEM teev tsuas yog phaj qhov ntev thiab qhov chaw.

Peb yuav tsum rov qab-engineer cov ntaub ntawv load. Peb suav cov shear thiab lub sij hawm, uas dictated tsis tsuas yog lub phaj thickness (peb mus nrog 42mm A572 Gr. 50) tab sis kuj cov qib ntawm thauj tog rau nkoj bolts - peb tau mus nrog ASTM F1554 Qib 105 rods. Peb kuj tau ntxiv ib qho kev nthuav dav tus thawj spec tsis muaj: jumbo hex washers kom zoo dua faib cov khoom ntawm lub phaj. Lub phaj tau tsim los ntawm lub khw uas tau txais cov hlau nyoos los ntawm lub zeb zoo li cov neeg nyob hauv Yongnian cheeb tsam, ua kom cov khoom zoo ib yam. Zaj lus qhia? Lub phaj tsuas yog ib feem ntawm lub system. Nws cov specs tsis muaj nuj nqis yam tsis xav txog lub bolts, lub hauv paus, thiab txoj kev thauj khoom.

Txoj hauj lwm no tseem qhia txog qhov tseem ceeb ntawm kev npaj nto. Lub 4U2U phaj muaj ib lub zeb nplai tiav. Rau qhov zoo grout adhesion, peb tau teev cov abrasive blasting rau ib tug nyob ze-dawb hlau tiav nyob rau hauv qab nto. Qhov no tsis yog nyob rau hauv ib qho kev cai, tab sis nws los ntawm kev ua tsis tiav ua ntej - lub phaj uas xeb ntawm qhov sib cuam tshuam thiab tso cai rau cov dej nkag mus rau hauv, cuam tshuam cov grout.

Tshaj Plaws: Corrosion thiab Lub Sij Hawm Ntev

Rau kev lag luam ib puag ncig, specs feem ntau nres ntawm qhov yuav tsum tau muaj qhov ntev thiab lub zog. Tab sis li cas txog corrosion? Hauv cov nroj tsuag tshuaj los yog chaw ntug dej hiav txwv, cov pa roj carbon monoxide 4U2U phaj yuav yog lub luag haujlwm. Kuv tau tawm tswv yim rau kub-dip galvanizing, tab sis qhov ntawd ntxiv thickness rau lub qhov thiab yuav tsum tau tapping los yog reaming tom qab. Rau cov ntawv thov high-precision, koj tuaj yeem teev cov txheej txheem corrosion-inhibitive txheej txheem hloov. Nws yog ib qho kev sib pauv ntawm durability thiab dimensional fidelity.

Lwm qhov kev saib xyuas yog cim thiab traceability. Rau cov ntawv thov tseem ceeb, txhua lub phaj yuav tsum tau cim tas mus li nrog tus lej xov tooj cua sov, qib khoom siv, thiab tus ID tshwj xeeb. Qhov no tso cai rau traceability rov qab mus rau daim ntawv pov thawj zeb xeem. Nws yog ib kauj ruam yooj yim uas tau hla dhau ntawm qhov nrawm, tab sis nws tsis muaj nuj nqis yog tias muaj lus nug tshwm sim xyoo tom qab thaum kuaj xyuas lossis tsis ua tiav. Cov kws tsim khoom lag luam yuav nkag siab txog qhov yuav tsum tau ua thiab tsim nws rau hauv lawv cov txheej txheem.

Wrapping It Up: Txoj Haujlwm Kev Ua Haujlwm

Yog li, rov qab mus rau lo lus nug qub: Cov lus teb tsis yog lub rooj zoo nkauj. Nws yog txheej txheem. Nws pib nrog kev kho tus lej ntawd raws li qhov qhia, tsis yog qhov kev qhia tag nrho. Koj yuav tsum khawb los yog txhais cov khoom siv specs, qhov ntev ntev (ua tib zoo saib xyuas qhov tseeb thiab txoj hauj lwm), lub tiaj tus, txoj kev fabrication, thiab nto tiav. Koj yuav tsum xav tias nws yog ib feem ntawm lub kaw lus nrog cov bolts thiab cov khoom siv hauv paus.

Kev koom tes nrog tus neeg tsim khoom uas nkag siab txog cov nuances no yog ib nrab ntawm kev sib ntaus sib tua. Lawv yuav tsum nug cov ntaub ntawv tsis tiav, tsis yog tsuas yog txiav txim. Seb nws yog ib tug loj tsim xws li Handan Zitai Fastener, nrog rau lawv cov khoom sib sib zog nqus cov hauv paus hniav hauv Tuam Tshoj lub hub hub, los yog lub khw tshwj xeeb hauv zos, lawv cov kev txawj hauv kev txhais cov lej tsis meej rau hauv cov khoom muaj zog, txhim khu kev qha yog qhov koj them nyiaj tiag tiag.

Thaum kawg, lub hom phiaj yog lub phaj uas haum zoo kawg nkaus, bears lub load yam tsis muaj kev tsis txaus siab, thiab kav ntev npaum li tus qauv nws txhawb nqa. Mus txog qhov yuav tsum tau saib yav dhau los 4U2U daim ntawv lo thiab tsim ib daim ntawv ua tiav, tsis paub meej. Qhov ntawd yog qhov sib txawv ntawm ib feem uas tsuas yog haum thiab ib feem uas ua haujlwm tiag tiag.
