Amaqhosha okukhangela

Ubungakanani Uluhlu

Umbhobho ngaphandle ubukhulu: 10.5-660.4mm (6-650A) (1/8-26B)

A=DN;B=NPS.

Ukuhlelwa kweBanga

I-JIS G 3455 inamabakala amathathu ngokobuncinane bokuqina kombhobho, oko kukuthiSTS370, STS410, kwayeSTS480.

Iinkqubo Zokuvelisa

Imibhobho kufuneka yenziwe ngaphandle komthungo ngentsimbi ebuleweyo.

Ukubunjwa kokugqibela kwahlulwe kwiindidi ezimbini, ezishushu-ezigqityiweyo kwaye zibandayo, kuxhomekeke kububanzi obungaphandle kunye nobukhulu bodonga.

Unyango lobushushu ngaphandle kwalolo lunikiweyo kwitheyibhile lunokwenziwa ngesivumelwano phakathi komthengi nomvelisi.

Uhlobo lokuphela kombhobho

Imibhobho iya kugqitywa ngeziphelo ezisicaba.

Ukuba isiphelo se-beveled sicacisiwe, i-tapered end shape yemibhobho enobunzima bodonga ≤ 22 mm iya kuhambelana ne-30-35 °, kunye nobubanzi be-bevel bombhobho wentsimbi bukhulu be-2.4mm.

Amacandelo eMichiza ye-JIS G 3455

Uhlalutyo lobushushu luya kuhambelana ne-JIS G 0320. Uhlalutyo lwemveliso luya kuhambelana ne-JIS G 0321.

Amaxabiso ohlalutyo lwe-thermal aya kuhambelana nezi mfuno zilandelayo:

Uphawu lwebakala C (iKhabhoni) Si (Silicon) Mn (Manganese) P (Phosphorus) S (Sulfur)
max max max
STS370 0.25% 0.10-0.35% 0.30-1.10% 0.35% 0.35%
STS410 0.30% 0.10-0.35% 0.30-1.40% 0.35% 0.35%
STS480 0.33% 0.10-0.35% 0.30-1.50% 0.35% 0.35%

Amaxabiso ahlalutyiweyo emveliso akufanele ahlangabezane namaxabiso kwitheyibhile kuphela, kodwa uluhlu lonyamezelo lwento nganye kufuneka luhambelane neemfuno zeThebhile 3 ye-JIS G 3021.

IPropati yoomatshini ye-JIS G 3455

Iimfuno jikelele zovavanyo lomatshini ziya kuhambelana nesolotya lesi-7 nelesi-9 le-JIS G 0404. Iindlela zesampulu zovavanyo lomatshini ziya kuhambelana neKlasi A ye-JIS G 0404, iGatya 7.6.

Amandla okuqina, iNqaku lokuZivuza okanye uQinisekiso loQinisekiso, kunye nokwandiswa

Indlela yokuvavanya iya kuhambelana nemigangatho ye-JIS Z 2241.

I-JIS G 3455 Amandla okuqina, inqaku lesivuno okanye uxinzelelo lobungqina, kunye nobude

Kwimibhobho ephantsi kovavanyo lwe-tensile usebenzisa i-specimen ye-12 okanye i-No.

Ukunyanzeliswa kokuchasa

Uvavanyo lunokushiywa ngokubona komenzi ukuba nje imibhobho iyanelisa ukuxhathisa okucacisiweyo.

I-specimen ifakwe phakathi kweeplatifomu ezimbini kwaye ifakwe kwi-compression de umgama H phakathi kwamaqonga ufikelele kwixabiso elichaziweyo.Lo mzekelo ujongwa ukuba awunazo iintanda.

H=(1+e)t/(e+t/D)

H: umgama phakathi kweeplatens (mm)

t: Ubukhulu bodonga lombhobho (mm)

D: ngaphandle kwedayamitha yombhobho (mm)

е: rhoqo kuchazwe kwibakala ngalinye lombhobho: 0.08 ye-STS370, 0.07 ye-STS410 kunye ne-STS480.

Uvavanyo lokuBendability

Isebenza kwimibhobho ene-diameter yangaphandle ≤50 mm njengoko kuchazwe ngumthengi.

I-specimen iya kukhululeka kwiintanda xa igobile kwi-angle ye-90 ° kunye nobubanzi bangaphakathi be-6 amaxesha angaphandle kombhobho.I-angle yokugoba iya kulinganiswa ekuqaleni kokugoba.

Uvavanyo lweHydrostatic okanye uvavanyo olungonakalisiyo

Uvavanyo lwe-hydrostatic okanye olungonakalisi luya kwenziwa kumbhobho ngamnye.

Uvavanyo lweHydrostatic

Bamba umbhobho ongekho ngaphantsi kobuncinci obuchaziweyo bovavanyo lwe-hydrostatic ubuncinane imizuzwana emi-5 kwaye ukhangele ukuba umbhobho unokumelana noxinzelelo ngaphandle kokuvuza.

Xa uMthengi engakhankanyi uxinzelelo lovavanyo, kwaye xa umbhobho uphantsi koxinzelelo oluncinci lovavanyo lwe-hydrostatic olunikiweyo, umbhobho uya kukwazi ukumelana nawo ngaphandle kokuvuza.

Ubukhulu bodonga lwegama 40 60 80 100 120 140 160
Ubuncinci boxinzelelo lovavanyo lwe-hydraulic, iMpa 6.0 9.0 12 15 18 20 20

Xa ubukhulu bodonga lobubanzi obungaphandle bombhobho wensimbi abukho ixabiso eliqhelekileyo kwitheyibhile yobunzima bombhobho wensimbi, kuyimfuneko ukusebenzisa ifomula ukubala ixabiso loxinzelelo.

P=2st/D

P: uxinzelelo lovavanyo (MPa)

t: Ubukhulu bodonga lombhobho (mm)

D: ngaphandle kwedayamitha yombhobho (mm)

s: 60 % yexabiso elincinci lenqaku lesivuno okanye ubungqina boxinzelelo olunikiweyo.

Xa ubuncinci boxinzelelo lovavanyo lwe-hydrostatic lwenani lesicwangciso esikhethiweyo lidlula uxinzelelo lovavanyo lwe-P olufunyenwe yifomula, uxinzelelo lwe-P luya kusetyenziswa njengoxinzelelo oluncinci lovavanyo lwe-hydrostatic endaweni yokukhetha olona xinzelelo luphantsi lovavanyo lwe-hydrostatic kwitheyibhile engentla.

Uvavanyo olungonakalisi

Umbhobho uya kuhlolwa ngokufunyaniswa kwe-ultrasonic okanye ukufunyanwa kwe-eddy yangoku.

Kwiimpawu zokufumanisa i-ultrasonic, izibonakaliso zeesampulu zereferensi eziqulethe imigangatho yereferensi yeklasi ye-UD echazwe kwi-JIS G 0582 iya kuthathwa njengenqanaba le-alamu, kwaye akukho signali elingana okanye enkulu kunenqanaba le-alamu liya kubakho.

Kwiimpawu ze-eddy zangoku zokubona, umqondiso wesampulu yereferensi equlethe umgangatho wesalathiso weklasi ye-EY njengoko kucacisiwe kwi-JIS G 0583 iya kuthathwa njengenqanaba le-alamu, kwaye akukho signali elingana okanye enkulu kunenqanaba le-alamu liya kubakho.

I-JIS G 3455 Itshathi yobunzima boMbhobho wentsimbi kunye neeShedyuli zemibhobho

Itshathi yobunzima bombhobho wentsimbi

Kwimeko yemilinganiselo engachazwanga kwiitafile zobunzima bombhobho, ifomyula ingasetyenziselwa ukubala.

W=0.02466t(Dt)

W: ubunzima beyunithi yombhobho (kg/m)

t: Ubukhulu bodonga lombhobho (mm)

D: ngaphandle kwedayamitha yombhobho (mm)

Qikelela ukuxinana kwe-7.85 g/cm³ kwityhubhu yentsimbi kwaye ujikeleze umphumo ukuya kumanani amathathu abalulekileyo.

Iishedyuli zombhobho

Umgangatho uxela iireyithingi ezintlanu zeShedyuli 40, 60, 80, 100, 120, kunye ne-160.

Ukwenzela lula, nantsi eyona shedyuli iqhele ukusetyenziswa 40 kunye neshedyuli 80.

Imbonakalo

Indawo yangaphakathi nangaphandle yombhobho iya kuba lula kwaye ikhululekile kwiziphene ezingathandekiyo ukuyisebenzisa.

Iziphelo zombhobho wensimbi ziya kuba kwii-angles ezichanekileyo kwi-axis yombhobho.

Ukumakisha

Ityhubhu nganye iya kubhalwa ngolu lwazi lulandelayo.

a) Uphawu lwebakala;

b) Uphawu lwendlela yokuvelisa;

Umbhobho wentsimbi ongenamthungo ogqityiweyo oshushu: -SH

Umbhobho wentsimbi ongenamthungo ogqityiweyo obandayo: -SC

c) ImilinganiseloUmzekelo 50AxSch80 okanye 60.5x5.5;

d) Igama lomenzi okanye uphawu lokuchonga.

Xa i-diameter yangaphandle yetyhubhu nganye incinci kwaye kunzima ukuphawula ityhubhu nganye, okanye xa umthengi efuna ukuba inyanda nganye yeetyhubhu imakishwe, inyanda nganye inokumakishwa ngendlela efanelekileyo.
