Piv nrog cov khoom hlau xws li cov hlau puag ncig, cov yeeb nkab steel feem ntau sib dua thaum khoov thiab lub zog torsion zoo ib yam. Nws yog ib hom kev lag luam hla ntu hlau, uas yog siv dav hauv kev tsim cov khoom siv thiab cov khoom siv kho tshuab, xws li cov roj laum kav, tsheb sib kis shafts, Tsheb kauj vab racks thiab steel scaffolding siv hauv kev tsim kho. Kev siv cov yeeb nkab steel los tsim cov nplhaib zoo li lub nplhaib tuaj yeem ua rau kev siv cov khoom siv tau yooj yim, ua kom yooj yim rau cov txheej txheem tsim khoom, thiab txuag cov ntaub ntawv thiab ua cov txiv neej-teev, xws li dov bearing rings, jack sleeves, thiab lwm yam. Nws tau raug tsim los ntawm steel. cov kav dej hauv xyoo 2013. Cov kav hlau hlau kuj yog cov khoom siv tsis tau rau ntau yam riam phom thiab cov tshuab ua tub rog. Cov phom phom thiab cov thoob yog ua los ntawm cov kav hlau. Cov kav hlau hlau tuaj yeem muab faib ua cov kav dej puag ncig thiab cov kav dej tshwj xeeb raws li lawv cov duab sib luag hauv cheeb tsam. Vim muaj qhov sib npaug ntawm qhov sib npaug, cov kua dej ntau tuaj yeem thauj tau nrog lub raj puag ncig. Thaum lub nplhaib seem raug rau sab hauv lossis sab nraud radial siab, lub zog sib xws, thiab feem ntau ntawm cov kav hlau steel yog cov kav dej.
1. Plasticity
Plasticity yog hais txog lub peev xwm ntawm cov ntaub ntawv hlau los tsim cov yas deformation (mus tas li deformation) yam tsis muaj kev puas tsuaj nyob rau hauv load.
2. Hardness
Hardness yog ib qho kev ntsuas ntawm hardness ntawm cov ntaub ntawv hlau. Txoj kev siv feem ntau los ntsuas qhov nyuaj hauv qhov kev tsim khoom no yog txoj kev indentation hardness, uas siv qee qhov geometric indenter los nias rau hauv qhov chaw ntawm cov khoom siv hlau yuav tsum tau kuaj nyob rau hauv ib qho kev thauj khoom, thiab tus nqi hardness yog txiav txim siab raws li qib. ntawm indentation.
Cov kev siv feem ntau suav nrog Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) thiab Vickers hardness (HV).
3. qaug zog
Lub zog, plasticity, thiab hardness yog tag nrho cov cim qhia ntawm cov khoom siv hluav taws xob ntawm cov hlau nyob rau hauv cov khoom zoo li qub. Nyob rau hauv qhov tseeb, ntau lub tshuab qhov chaw ua hauj lwm nyob rau hauv cyclic loads, nyob rau hauv no mob qhov chaw yuav qaug zog. Tshwj xeeb-zoo li tus steel kav nrog rau lwm yam cross-sectional shapes kuj yuav tsum tau.
Welded steel yeeb nkab rau kev thauj mus los tsis tshua muaj siab (GB / T3092-1993) tseem hu ua cov yeeb nkab dav dav, feem ntau hu ua clarinet. Nws yog welded steel yeeb nkab siv rau kev xa dej, roj, huab cua, roj thiab cua sov chav thiab lwm yam feem ntau txo cov kua dej thiab lwm yam. Cov phab ntsa tuab ntawm cov kav hlau yog muab faib ua cov kav hlau zoo tib yam thiab cov kav hlau tuab tuab; cov ntaub ntawv kawg kev sib txuas tau muab faib ua cov kav hlau tsis muaj xov (cov kav dej du) thiab cov kav hlau threaded. Qhov tshwj xeeb ntawm cov yeeb nkab steel yog qhia los ntawm nominal txoj kab uas hla (mm), uas yog kwv yees tus nqi ntawm lub puab kab. Nws yog kev cai los nthuav tawm hauv nti, xws li 11/2. Welded steel kav rau kev thauj mus los uas tsis tshua muaj siab tsis yog tsuas yog siv ncaj qha rau kev thauj mus los ntawm cov kua, tab sis kuj tseem siv los ua cov kav dej qub ntawm cov kav dej galvanized welded steel kav rau kev thauj mus los ntawm cov kua dej tsawg.
Galvanized welded steel yeeb nkab rau kev thauj mus los tsis tshua muaj siab (GB / T3091-1993) tseem hu ua galvanized welded steel yeeb nkab, feem ntau hu ua cov yeeb nkab dawb. Nws yog kub-dip galvanized welded (lub qhov cub welded los yog hluav taws xob welded) steel yeeb nkab siv rau conveying dej, roj, roj cua, cua sov chav, dej sov thiab lwm yam feem ntau txo cov kua los yog lwm yam hom phiaj. Cov phab ntsa tuab ntawm cov yeeb nkab steel yog muab faib ua cov yeeb nkab zoo tib yam galvanized steel yeeb nkab thiab tuab galvanized steel yeeb nkab; qhov kev sib txuas kawg hom yog muab faib ua cov yeeb nkab uas tsis yog xov galvanized steel thiab threaded galvanized steel yeeb nkab.
Ordinary carbon steel hlau casing (GB3640-88) yog cov yeeb nkab steel siv los tiv thaiv cov xov hlau hauv cov khoom siv hluav taws xob xws li kev lag luam thiab kev tsim vaj tse thiab kev teeb tsa ntawm cov tshuab thiab khoom siv.
Ncaj seam hluav taws xob welded steel yeeb nkab (YB242-63) yog cov yeeb nkab steel uas nws cov hlua txuas txuas mus rau qhov ntev ntawm cov yeeb nkab steel. Feem ntau muab faib ua metric fais welded steel yeeb nkab, hluav taws xob welded nyias-walled yeeb nkab, transformer txias roj yeeb nkab thiab lwm yam.
Kauv seam submerged arc welded steel yeeb nkab (SY5036-83) rau kev thauj mus los ntawm cov kua dej yog kub-kuav los tiag steel sawb raws li lub raj dawb paug, uas yog spirally tsim ntawm qhov kub thiab txias thiab welded los ntawm ob sab submerged arc vuam. Nws yog siv rau kauv seam ntawm kev thauj mus los ntawm cov kua dej. Cov yeeb nkab steel. Cov yeeb nkab steel muaj lub zog siab-cov kabmob muaj peev xwm thiab kev ua haujlwm vuam zoo. Tom qab ntau yam kev soj ntsuam nruj thiab kev sim, nws muaj kev nyab xeeb thiab txhim khu kev ntseeg siv. Cov yeeb nkab steel muaj txoj kab uas hla loj, kev sib kis tau zoo, thiab tuaj yeem txuag kev nqis peev hauv kev tso cov kav dej. Feem ntau yog siv hauv cov kav dej rau kev thauj cov roj thiab cov nkev.

4. Txheeb xyuas qhov dav thiab qauv ntawm cov menyuam txhawb nqa thiab lub siab rau cov menyuam ntawm cov khoom siv dov groove, thiab xyuas seb puas muaj qhov sib txawv ntawm qhov loj ntawm ob lub rollers, uas yuav ua rau qaug dab peg.
5. Siv lub vernier caliper los xyuas seb qhov zawj ntawm cov yeeb nkab steel puas tau teev tseg.
(3) Lub zawj tsim los ntawm lub tshuab dov zawj yuav tsum ua raws li cov cai hauv qab no
1, Qhov saum npoo ntawm cov yeeb nkab kawg mus rau qhov zawj yuav tsum du thiab tsis muaj qhov tsis sib xws thiab yob cov cim.
2, Qhov nruab nrab ntawm qhov zawj yuav tsum yog concentric nrog cov yeeb nkab phab ntsa, qhov dav thiab qhov tob ntawm qhov zawj yuav tsum ua tau raws li qhov yuav tsum tau ua, thiab xyuas seb hom clamp hom puas yog.
3. Siv cov roj nplaum rau ntawm lub nplhaib roj hmab sealing thiab xyuas seb lub nplhaib roj hmab sealing puas puas lawm. Lub lubricant yuav tsum tsis yog roj lubricant.
Welded kev twb kev txuas
1. Lub qhov ncauj ntawm cov yeeb nkab steel galvanized tsis nyob rau hauv txoj kab ncaj nraim thiab muaj teeb meem nrog lub qhov ncauj oblique ntawm cov yeeb nkab steel tom qab butting. Nws raug nquahu kom txiav cov yeeb nkab taub hau rau lub sijhawm luv luv ua ntej ua haujlwm.
2, Tom qab cov galvanized steel yeeb nkab nozzles txuas nrog, ob lub nozzles tsis nruj nreem txuas, uas ua rau cov thickness tsis sib npaug ntawm cov welded; thiab cov yeeb nkab yog elliptical vim nws tus kheej vim li cas los yog kev thauj mus los pob. Nws raug nquahu kom txiav cov yeeb nkab taub hau rau lub sijhawm luv luv. Txheej txheem dua.
3. Tom qab lub nozzles ntawm galvanized steel kav yog butted, hlwv tshwm sim ntawm nozzles:
4. Vim yog vim li cas thaum vuam.
5. Muaj zinc nodules nyob rau hauv lub nozzle, uas yuav ua rau vuam nyuaj thiab hlwv. Yog tias cov zinc nodules loj dhau thiab ntau cov kav dej, cov zinc nodules yooj yim yuav tsum tau muab tshem tawm.
Hlau kev twb kev txuas
1, Threaded buckle: Cov yeeb nkab hoop thiab threaded buckle tsis tuaj yeem tiv tauj tag nrho, loosen, txiav tawm qhov buckle random, thiab rov nruab cov xov.
2. Cov yeeb nkab steel thiab cov yeeb nkab hoop xov tsis sib xws thiab tsis tuaj yeem txuas tau. Cov yeeb nkab hoop yuav tsum tau hloov los yog cov cuab yeej yuav tsum tau kho thiab rov xov.
3. Nthuav luam tawm tom qab cov yeeb nkab steel yog threaded: Ntsuas seb cov phab ntsa tuab ntawm cov yeeb nkab steel puas tuaj yeem ua tau raws li tus qauv tuab ntawm cov yeeb nkab threaded.
