Zvinodhura here kugadzirisa bhaudhi rakatyoka pashongwe ye turbine yemhepo? Edza A4-80 giredhi Stainless simbi studs

Muindasitiri yemagetsi emhepo, kuvimbika kweshongwe mabhoti kunokanganisa zvakananga kushanda kwakachengeteka uye mutengo wekugadzirisa weyuniti. Traditional kabhoni simbi kana akajairwa Stainless simbi mabhaudhi anowanzoita kuneta kutsemuka, ngura uye kusunungura pasi penguva refu mitoro yemhepo uye nharaunda yekuzunguza, zvichikonzera kugadzirisa nguva nenguva uye kurasikirwa kwemagetsi. A4-80 giredhi Stainless simbi matudhi ari kuita sarudzo inosarudzika yekuvandudza kuvimbika muindasitiri yemagetsi emhepo nekuda kweakanakisa mamechanic zvimiro uye kushora.

Madhiri ekutadza mabhaudhi emagetsi emhepo

1. Kuneta kuputsika: Iyo shongwe inoiswa kune inochinjika mitoro panguva yekushanda, uye mabhaudhi anoburitsa microcracks uye anowedzera pasi pekunetsekana kwakadzokororwa.

2. Kutadza kutadza: Kudengenyeka kunoita kuti preload iora, uye kupfeka kwemicro-kufamba kunoitika pazvikamu zvekubatanidza.

3. Stress corrosion: Nzvimbo yekupfapfaidza munyu yemapurazi emhepo yemahombekombe inomhanyisa kutanga crack

4. Hydrogen embrittlement ngozi: Maitiro asina kunaka ekurapa kupisa anogona kutungamirira kunonoka kuputsika

Unyanzvi hwakanakira A4-80 giredhi Stainless simbi studs

1. Simba repamusoro-soro: Simba shoma shoma i800MPa, iyo inenge 30% yakakwirira kudarika 304 simbi isina tsvina.

2. Kuomarara kwakanyanya: mushure mekugadzirisa kupisa kurapwa, kurebesa ≥15%, yakanakisa kukanganisa kuramba

3. Corrosion resistance: 316 simbi isina tsvina substrate, yakanakisa kuita mumunyu pfapfaidzo nharaunda

4. Kugadziridza kurongeka: yakazara tambo yekutenderedza kuumba, kuve nechokwadi chedimensional kurongeka uye pamusoro pemhando.

Key tekinoroji zviratidzo verification

Kuita kuneta:

Pasi peyakaenzana 20-year load spectrum, hupenyu hwekuneta hunosangana nezvinodiwa zvekugadzira

Sarudzo mazano

Material simbiso:Inoda vatengesi kuti vape chitupa chekushandisa kuona kuti izvo zveMo zviri ≥2.1%

Maitiro ekuongorora:

Tarisa uone kana yakagadziriswa kupisa

Simbisa iyo yepamusoro passivation kurapwa maitiro

Nzvimbo dzekuisa:

Shandisa torque angle nzira yekudzora preload

Inokurudzirwa kushandisa ne-anti-loosening gaskets

Mazano ekugadzirisa:

Gara uchitarisa mamiriro ekutanga

Gadzira faira rekutsiva bhaudhi

Indasitiri application verification

Zvinoenderana neshumo yechitatu-bato rekuyedza agency, pasi pemamiriro akafanana ekushanda:

1. Hupenyu hwesevhisi hweA4-80 giredhi Stainless simbi studs ndeye 3-5 times iyo yeakajairika carbon simbi mabhaudhi.

2. Nguva yekuchengetedza inogona kuwedzerwa kusvika kumakore anopfuura 5

3. Mutengo wehupenyu hwakazara unoderedzwa neinopfuura 40%

Isu tinonyatso kutevedzera ISO 3506, ASTM A4-80 giredhi Stainless simbi studs inogadzirwa zvinoenderana nepasi rose zviyero seA193, uye inopa:

1. Zadzisa zvinyorwa zvetifiketi

2. Mechanical properties test report

3. Zvitupa zveti-party certification (zvakadai seDNV, TUV, nezvimwewo)

Kana iwe uchida ruzivo rwakadzama rwehunyanzvi kana sampuli yekuyedza, ndapota inzwa wakasununguka kutibata nesu.
