Mekhoa ea mantlha ea ho hloleha le tharollo

Ho robeha

Lisosa:

1. Ho beleha ho feteletseng ho feta matla a tlhahiso ea fastener.

2. Khatello ea baesekele e lebisang ho phatloheng ha mokhathala.

3. Litšitiso tse sa bonahaleng tsa li-fasteners tsa boleng bo tlase.

Thibelo:

1. Khetha lisebelisoa tse matla haholo (mohlala, Kereiti ea 8 kapa 12.9 alloy steel) bakeng sa lits'ebetso tse bohlokoa haholo.

2. Etsa tlhahlobo ea lintlha tsa finite (FEA) ho khetholla khatello ea maikutlo likopanong.

3. Li-fasteners tsa mohloli tse tsoang ho barekisi ba nang le setifikeiti sa ISO 9001 le mokhoa oa ho latella lintho.

Ho thethefatsa

Lisosa:

1. Ho thothomela kapa meroalo e matla e bakang ho potoloha butle.

2. Lipotoloho tsa ho atolosoa ha mocheso / ho fokotsa mocheso.

3. Torque ea pele e sa lekaneng nakong ea ho kenya.

Thibelo:

1. Sebelisa mekhoa ea ho notlela ka mochini (mohlala, linate tsa senotlolo sa nylon, liwasha tse notlelang litšepe).

2. Kenya li-threadlockers tsa matla a mahareng (mohlala, Loctite 243) bakeng sa ho hanyetsa ho thothomela.

3. Kenya ts'ebetsong li-wrenches tsa torque tse lekantsoeng le lisebelisoa tsa tlhahlobo ea torque ea dijithale.

Kobo

Lisosa:

1. Metsoako ea galvanic lipakeng tsa litšepe tse sa tšoaneng (mohlala, ho kopana le tšepe-aluminium).

2. Ho pepesehela mongobo, sefafatsi sa letsoai, kapa lik'hemik'hale tsa indasteri.

3. Ho senyeha ha liphahlo tse sireletsang ka nako.

Thibelo:

1. Hlalosa lisebelisoa tse sa jeng (316 stainless steel, A4 stainless, kapa hot-dip galvanized steel).

2. Kenya litšitiso tsa dielectric (mohlala, motsoako oa Duralac) lipakeng tsa litšepe tse fapaneng.

3. Bakeng sa tikoloho e feteletseng, nahana ka plating ea zinc-nickel kapa liphahlo tsa Dacromet®.

Ho hlobolisa likhoele

Lisosa:

1. Ho tiisa ho feta tekano ka lisebelisoa tse sa nepahalang (mohlala, bakhanni ba nang le tšusumetso ntle le taolo ea torque).

2. Litekanyetso tse sa lumellaneng (metric vs. imperial).

3. Boleng bo bobe ba likhoele ho li-fasteners tse sa lumellaneng.

Thibelo:

1. Sebelisa likhoele tse rolotsoeng, tse bonts'ang matla a 20-30% a holimo ho feta likhoele tse khaotsoeng.

2. Netefatsa likhoele ka li-go/no-go gauges nakong ea tlhahlobo ea boleng.

3. Bakeng sa li-substrates tse bonolo joalo ka aluminium, kenya likhoele (mohlala, Helicoil®) ho matlafatsa boitlamo.

Lithuto Tsa Mohlala: Litlhaloso Tse Sebetsang

Offshore Wind Turbine Bolt Fracture

Hlahisa: Liboutu tsa Kereiti ea 5 lihokelong tsa turbine flange li ile tsa hloleha pele ho nako ka lebaka la ho bola ha metsi a letsoai le ho phalla ha libaesekele.
Tharollo: E nkeloe sebaka ke liboutu tsa Inconel 718 tse tlositsoeng ka HVOF tungsten carbide, tse fihlelang bophelo ba ts'ebeletso ea lilemo tse 10.

Likoloi Kopano Line Downtime

Hlahisa: Ho thothomela ho ile ha lokolla liboutu tsa bohlokoa tsa makoloi, tsa baka ho se tsamaisane hantle.
Tharollo: Li-torque nuts tse amohetsoeng (DIN 985) tse kopantsoeng le ultrasonic bolt tension monitoring, ho fokotsa nako ea ho theoha ka 75%.

Mekhoa e Molemo ka ho Fetisisa ea ho Khetha le ho Kenyeha ka Fastener

• Ho lumellana ha Lintho

  • Libaka tse nang le mocheso o phahameng: Khetha A286 tšepe e sa hloekang kapa li-alloys tse thehiloeng ho nickel.

  • Ho pepeseha ha lik'hemik'hale: Hastelloy® kapa li-fasteners tse koahetsoeng ke PTFE li hanela li-acidic/alkaline agents.

• Mehopolo ea Moralo

  • Qoba likarolo tse bohale haufi le lihlooho tsa fastener; liphetoho tsa radius li fokotsa khatello ea maikutlo.

  • Bakeng sa lisebelisoa tse kopantsoeng, sebelisa li-screws tsa mahetla ho thibela delamination.

• Melao ea ho kenya

  • Latela melaoana ea ISO 16047 ea torque-tension bakeng sa manonyeletso a bolt.

  • Bakeng sa lits'ebetso tsa bohlokoa, sebelisa liteko tsa ultrasonic ho netefatsa ho nepahala ha boima ba clamp.

Qetello

Taolo e sebetsang ea fasteners ke leano le bolokang chelete e ngata ho fokotsa likotsi tsa ts'ebetso. Ka ho hokahanya khetho ea thepa, moralo le mekhoa ea ho kenya le litlhoko tsa ts'ebetso, mekhatlo e ka fokotsa sekhahla sa ho hloleha haholo. Litlhahlobo tsa khafetsa, tšebelisano ea bafani ba thepa, le ho latela melao ea machaba (mohlala, ASTM, DIN) ho netefatsa ts'epo ea nako e telele.

Mabapi le rona

Ho Fasto, re ts'epahalla sekoaelo se seng le se seng. Ka lilemo tse fetang leshome tsa boiphihlelo ba ho hlahisa Confirmat le li-fasteners tse khethehileng, re fana ka litharollo tse etselitsoeng ho loants'a kutu, mokhathala le ho hlepha. Hore na o hloka boholo bo tloaelehileng ba indasteri kapa lijalo le lijeometri tse ikhethileng ka ts'ebeliso, sehlopha sa rona se ntlafatsa li-fasteners bakeng sa litlhoko tsa hau tsa ts'ebetso. Ikopanye le rona hoinfo@fasto.cnbakeng sa tataiso e hlophisitsoeng ea tekheniki, litheko tsa molumo, kapa tlhahlobo ea kotsi ea ho hloleha - hobane thibelo e qala ka sehokelo se nepahetseng.
