Imbaraga-Zikomeye: Aho nigihe cyo kuzikoresha

2026-05-25

Niki gituma Bolt ikomera cyane?

Imbaraga-zikomeye zisobanurwa nibintu bitatu byingenzi:

Imbaraga zingana - umutwaro ntarengwa bolt irashobora kwihanganira mbere yo kuvunika (bipimirwa muri MPa)
Gutanga imbaraga - umutwaro aho bolt itangira guhinduka burundu
Umutwaro uhamya - pre-tension ikoreshwa mugihe cyo kwishyiriraho imbaraga zo gufatana hamwe

Imbaraga zikomeye cyane zikorwa mubyuma biciriritse bya karubone cyangwa ibyuma bivanze kandi bigakorerwa ubushyuhe (kuzimya no gutuza) kugirango bigere kumikorere ikenewe. Ubuso bwo hejuru - nka plaque ya zinc, Dacromet, cyangwa Luxubao - bikoreshwa mukuzamura ruswa bitabujije imbaraga.

UKURI Icyiciro cya 10.9 cya bolts gifite imbaraga zingana na 1.000 MPa - zirenga 3 × zikomeye kuruta icyiciro gisanzwe cya 4.6.

Inzego zingenzi zo gusaba

Imbaraga zikomeye zikoreshwa hafi yinganda zose ziremereye. Imbonerahamwe ikurikira irerekana ahantu hasanzwe hasabwa hamwe nubwoko bwihuta:

Inganda / Umurenge	Porogaramu isanzwe	Ubwoko bwa Bolt / Byihuta
Ibyuma byubaka & Ubwubatsi	Imirongo-y-inkingi ihuza, ibyapa fatizo, inanga	Hex-imbaraga nyinshi cyane (Icyiciro 8.8 / 10.9)
Ikiraro & Ibikorwa Remezo	Guhuza flange, ibiraro bya girder	ASTM A325 / A490 imiterere ya bolt
Imashini Ziremereye & Ibikoresho	Inzu ya Gearbox, kanda kumurongo, gari ya moshi	Hex hex bolt, sock head cap screw
Umuyaga Umuyaga & Ingufu	Umunara flange bolts, inteko za nacelle	Icyiciro cya 10.9 / 12.9 studio bolt hamwe nutubuto
Imodoka & Gariyamoshi	Moteri ya moteri, chassis bolts, amafi ya gari ya moshi	Flange bolt, ibinyabiziga bitwara, shiraho umugozi
Ubwato & Marine	Isahani yuzuye, guhuza byinshi	Umuyonga / Dacromet-yometse kuri hex bolt
Amavuta na gazi / peteroli	Umuyoboro wa flanges, umupfundikizo wumuvuduko	ASTM A193 B7 studio bolt, umutobe uremereye
Ikirere & Defence	Ibikoresho bifata ibyuma byubaka	Titanium / alloy bolt, NAS / MS bisanzwe

Ibyuma byubaka & Ubwubatsi

Inganda zubwubatsi nizo zikoresha cyane imbaraga za bolts. Ihuza rya bolt risimbuza gusudira gakondo mumirongo-y-inkingi, bitanga kwishyiriraho byihuse, kugenzura byoroshye, no kurwanya cyane imitwaro yimitingito.

Hex bolts (Icyiciro cya 8.8 / 10.9) - ikoreshwa muguhuza umwanya-mukanya, ibyuma byibanze, hamwe nibisahani.
Inkingi ya Anchor - yashyizwe mu rufatiro rufatika kugirango ibe ifite ibyuma byubaka
Hex hex bolts hamwe nimbuto - zisanzwe kuri AISC na EN 1090 zujuje ibyuma byerekana ibyuma

INAMA Kugirango uhuze kunyerera, burigihe ukoreshe ASTM A325 cyangwa A490 bolts hamwe no gukaraba gukomeye hamwe na kalibatifike ya torque.

Ikiraro & Ibikorwa Remezo

Kubaka ikiraro bisaba kwihuta bishobora kwihanganira imizigo nzima, kwaguka kwinshi, hamwe nimyaka myinshi yibidukikije. Imbaraga zikomeye zubatswe zisobanurwa mumirongo mpuzamahanga yikiraro harimo AASHTO, Eurocode 3, na GB / T.

Flange bolts - ihuza ibice byicyuma kuri kiraro
Kwiga bolts hamwe nutubuto - umutekano wagutse hamwe no guteranya amasahani
Dacromet isize hex bolts - yerekanwe kubikorwa byikiraro cyinyanja ninyanja kugirango birinde ruswa

Umuyaga Umuyaga & Amashanyarazi

Iminara ya turbine yumuyaga ikusanyirizwa hamwe ikoresheje diametero nini nini ya flange bolts - akenshi Icyiciro cya 10.9 cyangwa 12.9 - ikorerwa imitwaro yumunaniro mwinshi mubuzima bwabo bwimyaka 25. Bolt preload yukuri irakomeye; Bolt yiyemeje gutera umunaniro umunaniro kunanirwa, mugihe hejuru ya bolts ishobora gutanga umusaruro.

Umunara wa flange (M36 - M72, Icyiciro cya 10.9) - gusaba cyane imbaraga zikoreshwa cyane murwego rwingufu zishobora kuvugururwa
Fondasiyo ya Anchor - ihuza umunara na fondasiyo ya beto
Nacelle na rotor hub bolts - guhuza imiterere yimbere hamwe nibisabwa byumuriro

ICYITONDERWA Zinc-flake / Luxubao isize bolts ikundwa mugukoresha umunara wumuyaga - itanga imbaraga zo kurwanya ruswa kandi ni hydrogène-idafite imbaraga.

Imashini ziremereye & ibikoresho byinganda

Imashini, imashini, ibikoresho byo gucukura amabuye y'agaciro, hamwe na bokisi yinganda zitanga imizigo ikabije ikenera imbaraga zifatika zikomeye. Kurekura Bolt mumashini azunguruka birashobora gutera kunanirwa gukabije hamwe nigihe cyo gukora.

Sock head cap screws (Icyiciro cya 12.9) - ikoreshwa ahantu hafungiwe aho hex isanzwe itaboneka
Flange bolts - itanga kwikunda no kurwanya imbaraga zogosha kuruhande rwimashini
Shiraho imigozi na grub screw - umutekano uzunguruka ibice bitagira imitwe

Amavuta, gaze & peteroli

Umuyoboro wa flange uhuza hamwe nubwato bwumuvuduko mubikorwa bya peteroli na gaze bikora munsi yumuvuduko mwinshi, ubushyuhe bukabije, nibitangazamakuru byangirika. Kwizirika muri ibi bidukikije bigomba kuba byujuje ASME B16.5 na ASTM A193 / A194.

ASTM A193 B7 sitidiyo (Cr-Mo alloy ibyuma) - inganda zinganda zo guhuza ubushyuhe bwo hejuru bwa flange
2H iremereye cyane (ASTM A194) - ihujwe na sitidiyo ya B7 kuri flanges yagabanijwe.
Incoloy / super-alloy bolts - yerekanwe kubintu byangirika cyane cyangwa serivise ya kirogenike

Kurinda ruswa kuri Bolt-Imbaraga nyinshi

Ruswa niyo mpamvu nyamukuru itera kwihuta hakiri kare hanze yinganda. Guhitamo uburyo bwiza bwo kuvura ni ngombwa - cyane cyane kumashanyarazi akomeye aho hydrogène yinjira muri electroplating ningaruka nyazo ziri hejuru yicyiciro cya 10.9.

Ipfunyika ya Dacromet - ishingiye ku mazi, idafite chromate, 480–1000 + h irwanya umunyu-spray; umutekano ku cyiciro cya 10.9 / 12.9
Ipfunyika ya Luxubao (zinc-flake) - isa na Geomet / Delta-Tone; byiza cyane ingufu zumuyaga nubwubatsi buremereye
Ashyushye cyane - ikwiranye nicyiciro cya 8.8 na munsi; ntibisabwa hejuru yicyiciro cya 10.9 kubera ibyago bya hydrogen
Zinc electroplating - amahitamo yubukungu murugo cyangwa hasi-ibidukikije
Ibyuma bidafite ingese (A2-70 / A4-80) - birinda ruswa; ntayindi myenda isabwa

Kuberiki Hitamo FUJINRUI-Imbaraga Zihambiriye?

Yakozwe kuri ISO 898-1, ASTM A325 / A490, na DIN 931/933
Ubwoko bwuzuye bwo gutwikira: Dacromet, Ruspert, isahani ya zinc, ishyushye-dip galvanised, fosifate
Ingano kuva M6 kugeza M64, amanota yingufu 8.8 / 10.9 / 12.9
Icyemezo cya gatatu cyibizamini byo gupima birahari (tensile, gukomera, umunyu-spray)
Ibiciro birushanwe hamwe nigihe cyihuta cyo kuyobora kubwinshi OEM nibisabwa byumushinga
