Taw qhia rau Kev Ua Haujlwm ntawm Acorn Ceev
1. Txuas ob qhov tuab tuab
Cov xov yog muab rau ntawm ob qhov kawg. Ib kawg yog screwed rau hauv threaded qhov ntawm lub cev khoom, thaum lwm kawg yog haum nrog flanges los yog npog daim hlau, ruaj nrog washers thiab ceev.
Ib qho yooj yim - taub hau bolts muaj luv shanks thiab tsis tuaj yeem nkag mus rau cov tuab tuab, qhov teeb meem daws tau zoo kawg nkaus los ntawm stud bolts.
2. Yooj yim disassembly yam tsis muaj kev puas tsuaj puag hauv cov xov
Tsuas yog cov txiv ntoo sab nraud yuav tsum tau muab tshem tawm rau kev saib xyuas, tsis tas yuav tsum tau tshem tag nrho cov ntsia liaj qhov rooj. Qhov no tiv thaiv rov qab hnav thiab xov stripping ntawm cov xov sab hauv ntawm cov khoom vaj tse.
Nws yog dav siv rau cov khoom siv uas yuav tsum tau qhib lub hau npog rau kev tshuaj xyuas.
3.Fasten thiab foob flanges
Siv ua khub rau cov kav dej flanges, lub nkoj siab flanges thiab valve flanges kom sib npaug ntawm cov gaskets thiab ua tiav airtight thiab kua- nruj sealing.
4. Tshwj xeeb rau siab - kub thiab siab - siab ua hauj lwm tej yam kev mob
Dav siv nyob rau hauv siab -kub boilers, chemical pipelines thiab siab hlab ntsha. Ib leeg- taub hau bolts zoo li yuav ntes nyob rau hauv qhov kub thiab txias, whereas stud bolts muab kev ua haujlwm ruaj khov dua.
II. Hom Daim Ntawv Thov Scenarios
1.Xaus npog ntawm cov hlab ntsha siab thiab lub tank cia
2.Kev sib txuas ntawm cov kav dej flanges thiab li qub
3.Cav lub tog raj kheej taub hau thiab lub twj tso kua mis
4.Pwm thiab hnyav- cov khoom siv ua haujlwm
5. Siab - kub thiab siab - cov kav dej siab rau kev lag luam chemical thiab roj & roj
III. Qhov sib txawv ntawm Standard Hex Head Bolts
•Hex taub hau bolts: Nruab nrog lub taub hau hexagonal ntawm ib kawg, tsuas muaj peev xwm ntawm ib leeg - sab nruj. Tsis siv rau cov khoom tuab; nquag disassembly yuav ua rau cov xov sab hauv ntawm lub hauv paus.
• Stud bolts: Headless nrog threads ntawm ob kawg. Ib qho kawg yog threaded rau hauv cov khoom siv lub cev, thiab sab nraud yog clamped los ntawm txiv ntseej. Zoo tagnrho rau cov vaj tsev tuab, nquag disassembly thiab siab - cov ntawv thov kev sib khi.
IV. Common Material Qib & Kev siv
• Qib4.8 Carbon Steel: General low - cov khoom siv siab thiab ib txwm - cov kav dej kub
•Qib 8.8 / 10.9 High Tensile Steel: Hydraulic systems thiab siab -siab flanges
• 304 / 316Stainless hlau: Corrosive tshuaj ib puag ncig thiab kev kho dej
•35CrMo / 42CrMo Alloy Steel: Siab - kub siab - siab boilers thiab siab hlab ntsha
Taw qhia rau cov khoom thiab qhov ntev ntawm Acorn Ceev
Acorn txiv ntseej yog ib txwm tsim los ntawm siab - zoo 10B21 carbon steel. High- cov khoom muaj zog yog ua los ntawm 35 # steel thiab 45 # steel, uas tau dhau los quenching thiab tempering kub kho nrog hardness HRC27-32, sib piv qib 8.8 bolts zoo kawg nkaus.
304 thiab 316 stainless hlau cov ntaub ntawv muaj nyob rau hauv kev thov rau corrosive ib puag ncig nrog acid thiab alkali.
Peb cov khoom ua raws li GB / T923 tus qauv, xws li M6 txog M24. Hla -flats dimension, tag nrho qhov siab thiab sab hauv kab noj hniav qhov tob tag nrho raws li lub teb chaws tus qauv. Tsis yog- qhov loj me tuaj yeem hloov kho raws li cov neeg siv khoom xav tau.
Muaj cov khoom tiav: electro-galvanized, kub-dip galvanized, dacromet, dub oxide tiav.
