Iimveliso zethu ezinxulumeneyo
Ubungakanani Uluhlu
Ifanelekile kwimibhobho yentsimbi kunye nobubanzi obungaphandle be-15.9-139.8mm.
Iimpahla ezingekasilwa
Imibhobho iya kwenziwa ukusuka kwiintsimbi ebulewe.
Insimbi ebuleweyo luhlobo lwensimbi apho i-oksijini isuswa kwintsimbi ngokongezwa kwe-deoxidizer efana ne-silicon, i-aluminium, okanye i-manganese ngexesha lokunyibilika.
Olu nyango lubangela ukuba intsimbi ingabikho kwiibhubhu zomoya okanye ezinye izinto ezifakwe kwi-gaseous, eziphucula ukufana kunye neepropati ezipheleleyo zentsimbi.
Iinkqubo zokuVeliswa kwe-JIS G 3461
Ukudibanisa iindlela zokuvelisa umbhobho kunye neendlela zokugqiba.
ityhubhu yentsimbi engenamthungo egqityiweyo eshushu: SH
ityhubhu yentsimbi engenamthungo egqityiweyo ebandayo: SC
Njengokumelana nombane ityhubhu yentsimbi edityanisiweyo: EG
Ubushushu obugqityiweyo bokumelana nombane obudityanisiweyo ityhubhu yentsimbi: EH
Ukumelana nombane ogqityiweyo ogqityiweyo ityhubhu yentsimbi edityanisiweyo: EC
Xa umbhobho wentsimbi wenziwa nge-resistance welding, ubuhlalu be-weld buya kususwa kwiindawo zangaphakathi nangaphandle ukwenzela ukuba ubuso bombhobho bube bushelelezi kunye ne-contour.
Amaso eweld kumphezulu ongaphakathi akanakususwa ukuba umthengi nomvelisi bayavuma.
Uhlobo lokuphela kombhobho
Umbhobho wentsimbi kufuneka ube mcaba.
Unyango lobushushu
Inkqubo yokwenziwa kombhobho wensimbi kunye nebakala layo lezinto ezihambelanayo kufuneka liqwalaselwe xa ukhetha unyango olufanelekileyo lokushisa.
Iinkqubo ezahlukeneyo zokuvelisa kunye namabakala ezinto eziphathekayo zinokufuna iindlela ezahlukeneyo zonyango lobushushu ukufezekisa iipropati ezifunwayo zoomatshini kunye ne-microstructure.
Ukubunjwa kwemichiza ye-JIS G 3461
Iindlela zokuhlalutya i-thermaliya kuhambelana nemigangatho ekwi-JIS G 0320.
Izinto ezidibanisayo ngaphandle kwezo zinokongezwa ukufumana iipropati ezithile.
Indlela yeuhlalutyo lwemvelisoiya kuhambelana nemigangatho ekwi-JIS G 0321.
Xa imveliso ihlaziywa, ixabiso lokuphambuka lokubunjwa kweekhemikhali zombhobho liya kuhlangabezana neemfuno zeThebhile 3 ye-JIS G 0321 yeepayipi zetsimbi ezingenamthungo kunye neThebhile 2 ye-JIS G 0321 kwimibhobho yensimbi echasayo.
Ukusebenza koomatshini be-JIS G 3461
Iimfuno jikelele zovavanyo lomatshini ziya kuhambelana neCandelo lesi-7 nele-9 le-JIS G 0404.
Nangona kunjalo, indlela yesampulu yovavanyo lomatshini iya kuhambelana neemfuno zeKlasi A amalungiselelo kwiCandelo 7.6 le-JIS G 0404.
Amandla okuqina, iNqaku lokuZivuza okanye uQinisekiso loQinisekiso, kunye nokwandiswa
Xa uvavanyo lwe-tensile luqhutyelwa kwisiqwenga soVavanyo No.
Ukunyanzeliswa kokuchasa
Uvavanyo lwe-Resistance olucaba alufunwa kumbhobho wentsimbi ongenamthungo.
Indlela yoVavanyo Beka umfuziselo kumatshini kwaye uwucande de umgama phakathi kwamaqonga amabini ufikelele kwixabiso elikhankanyiweyo.H.Emva koko jonga umboniso wokuqhekeka.
Xa uvavanya ukuxhathisa okubalulekileyo umbhobho odityanisiweyo, umgca phakathi kwe-weld kunye nombindi wombhobho u-perpendicular ukuya kulwalathiso loxinzelelo.
H=(1+e)t/(e+t/D)
H: umgama phakathi kweeplatens (mm)
t: Ubukhulu bodonga lwetyhubhu (mm)
D: ngaphandle kwedayamitha yombhobho (mm)
е: rhoqo kuchazwe kwibakala ngalinye lombhobho.STB340: 0.09;STB410: 0.08;STB510: 0.07.
Ipropati evuthayo
Uvavanyo lwePropati yeFlaring alufunwa kwiityhubhu ezingenamthungo.
Esinye isiphelo se-specimen sivutha kwiqondo lokushisa (5 ° C ukuya ku-35 ° C) kunye nesixhobo se-conical kwi-angle ye-60 ° de i-diameter yangaphandle ikhuliswe ngumlinganiselo we-1.2 kwaye ihlolwe ukuqhekeka.
Le mfuneko iyasebenza nakwiityhubhu ezinobubanzi obungaphandle obungaphezu kwe-101.6 mm.
Reverse Flattening Resistance
Isiqwenga sovavanyo esicandisiweyo esibuyela umva kunye nendlela yovavanyo iya kuba ngolu hlobo lulandelayo.
Sika ubude be-100 mm ubude bovavanyo ukusuka kwelinye icala lombhobho kwaye usike isiqwenga sovavanyo kwisiqingatha se-90 ° ukusuka kumgca we-weld kumacala omabini omjikelezo, uthabathe isiqingatha esiqulethe i-weld njengeqhekeza lovavanyo.
Kwiqondo lobushushu begumbi (5 °C ukuya kuma-35 °C) thambisa umfuziselo ube yipleyiti eneweld ngaphezulu kwaye ujonge umfuziselo wokubona iintanda kwiweld.
Uvavanyo lobulukhuni
Uphawu lwebakala | Ukuqina kwe-Rockwell (intsingiselo yexabiso lezithuba ezintathu) I-HRBW |
STB340 | 77 ubuninzi. |
STB410 | 79 ubuninzi. |
STB510 | 92 ubuninzi. |
Uvavanyo lwe-Hydraulic okanye uvavanyo olungonakalisi
Uvavanyo lwe-Hydraulic okanye olungonakalisi luya kwenziwa kumbhobho ngamnye.
Uvavanyo lweHydraulic
Bamba ingaphakathi lombhobho ubuncinane okanye uxinzelelo oluphezulu lwe-P ubuncinane imizuzwana emi-5, uze ukhangele ukuba umbhobho unokumelana noxinzelelo ngaphandle kokuvuza.
P=2st/D
P: uxinzelelo lovavanyo (MPa)
t: Ubukhulu bodonga lwetyhubhu (mm)
D: ngaphandle kwedayamitha yombhobho (mm)
s: 60 % yexabiso eliphantsi elichaziweyo lenqaku lesivuno okanye ubungqina boxinzelelo.
P max.10 MPa.
Ukuba uMthengi uchaza uxinzelelo, olukhulu kunoxinzelelo olubaliweyo lovavanyo lwe-P okanye i-10 MPa, uxinzelelo lovavanyo olusetyenzisiweyo luya kuvunyelwana ngalo nguMthengi kunye nomenzi.
Iya kucaciswa kwi-0.5 MPa yonyuso ukuba ngaphantsi kwe-10 MPa kunye ne-1 MPa yonyuso ukuba i-10 MPa okanye ngaphezulu.
Uvavanyo olungonakalisi
Uvavanyo olungonakaliyo lweetyhubhu zetsimbi kufuneka lwenziwe ngovavanyo lwe-ultrasonic okanye lwe-eddy lwangoku.
Kwiimpawu zokuhlola i-ultrasonic, isignali evela kwisampulu yereferensi equlethe umgangatho wereferensi yeklasi ye-UD njengoko ichazwe kwi-JIS G 0582 iya kuthathwa njengenqanaba le-alamu kwaye iya kuba nesiseko esisisiseko esilingana okanye esikhulu kunezinga le-alamu.
Kwiimpawu zokuhlola zangoku ze-eddy, umqondiso osuka kumgangatho wereferensi ochazwe kwi-JIS G 0583 kunye nodidi lwe-EY luya kuthathwa njengenqanaba le-alamu, kwaye akuyi kubakho mqondiso olingana okanye omkhulu kunomgangatho we-alamu.
Itshathi yobunzima bombhobho ye-JIS G 3461
Idatha kwitshathi yobunzima isekelwe kwifomula engezantsi.
W=0.02466t(Dt)
W: ubunzima beyunithi yombhobho (kg/m)
t: Ubukhulu bodonga lombhobho (mm)
D: ngaphandle kwedayamitha yombhobho (mm)
0.02466: into yokuguqula ukufumana iW
Le fomyula ingentla luguqulelo olusekwe kuxinaniso lweetyhubhu zentsimbi ze-7.85 g/cm³ kwaye iziphumo zisondezwe kumanani amathathu abalulekileyo.

Imbonakalo
Ubuso bangaphakathi nangaphandle bombhobho wensimbi kufuneka bube bushelelezi kwaye bukhululekile kwiziphene ezingathandekiyo ukusebenzisa.Ukuxhathisa umbhobho wentsimbi, ukuphakama kwe-weld yangaphakathi ≤ 0.25mm.
Kwimibhobho yensimbi ene-OD ≤ 50.8mm okanye ubukhulu bodonga ≤ 3.5mm, I-INSIDE CAMPES ≤ 0.15mm ingafuneka.
Umphezulu wombhobho wensimbi unokulungiswa ngokusila kunye nokutshiza, umatshini, okanye ezinye iindlela.Ubude bodonga olulungisiweyo
ingaphakathi kobunzima bodonga oluchaziweyo, kwaye ubuso bendawo elungisiweyo buya kuba lula.
Ukumakisha
Thatha indlela efanelekileyo yokuleyibheliza olu lwazi lulandelayo.
a) Uphawu lwebakala;
b) Uphawu lwendlela yokuvelisa;
c) Imilinganiselo: i-diameter yangaphandle kunye nobukhulu bodonga;
d) Igama lomenzi okanye uphawu lokuchonga.
Izicelo ze-JIS G 3461
Isetyenziswa kakhulu kwimibhobho yamanzi, imibhobho engumbhobho, imibhobho yesifudumezisi esikhulu, kunye nemibhobho ye-preheater yomoya kwiibhoyila, ezi ityhubhu zentsimbi zekhabhoni zisetyenziselwa ukuqonda utshintshiselwano lobushushu ngaphakathi nangaphandle kwetyhubhu.
Ukongezelela, ezi zityhubhu zisetyenziswa ngokubanzi kumashishini ekhemikhali kunye nepetroleum kwimibhobho yokutshintsha ubushushu, iityhubhu ze-condenser kunye ne-catalyst tubes.
Nangona kunjalo, azifanelekanga kwiityhubhu zokutshisa ukushisa kunye neetyhubhu zokutshintsha ubushushu kubushushu obuphantsi.
