Litlhoko tsa Thepa le Mechini bakeng sa A325M Heavy Hex Bolts

Liboutu tsa hex tse boima tsa A325M ke liboutu tse nang le matla a phahameng tse sebelisoang haholo kahong ea tšepe, haholo lits'ebetsong tse hlokang matla a phahameng a ho tsitsa le ho ts'epahala. Liboutu tsena li etselitsoe ho fihlela litlhoko tse thata tsa thepa le thepa ea mochini ho netefatsa ts'ebetso ea tsona lits'ebetsong tsa bohlokoa tsa ho jara mojaro.

Litlhoko tsa lintho tse bonahalang:
Liboutu tsa A325Mhangata li entsoe ka tšepe ea carbon e mahareng, e phekolehang mocheso ho fihlela thepa e lakatsehang ea mochini. Thepa e tlameha ho lumellana le meeli e itseng ea metsoako ea lik'hemik'hale ho etsa bonnete ba ho lumellana le ts'ebetso. Lintho tse ka sehloohong tse entsoeng ka tšepe li kenyelletsa carbon, manganese, phosphorus, sebabole le boron. Likahare tsa carbon li laoloa ka hloko ho leka-lekanya matla le ductility, ha boron e atisa ho eketsoa ho matlafatsa boima nakong ea phekolo ea mocheso. Tšepe e boetse e tlameha ho hloka bofokoli bo kang seams, laps, kapa inclusions tse ka senyang botšepehi ba bolt.

Thepa ea Mechini:
Thepa ea mochini ea liboutu tsa A325M e bohlokoa ts'ebetsong ea bona. Li-bolts tsena li arotsoe ka mefuta e 'meli ho latela thepa ea bona ea mechine: Mofuta oa 1 le oa Mofuta oa 3. Mefuta ea mofuta oa 1 e entsoe ka tšepe ea carbon kapa alloy mme e loketse ho sebelisoa ka kakaretso. Liboutu tsa mofuta oa 3, ka lehlakoreng le leng, li entsoe ka tšepe ea boemo ba leholimo, e fanang ka khanyetso e matlafalitsoeng ea kutu bakeng sa lits'ebetso tsa kantle.

Matla a tensile a liboutu tsa A325M a tlameha ho fihlela tlhokahalo e tlase ea 830 MPa (120 ksi), ka matla a tlhahiso a bonyane 660 MPa (95 ksi). Elongation, e lekanyang ductility ea thepa, e tlameha ho ba bonyane ba 14% ho netefatsa hore bolt e khona ho mamella deformation ntle le ho robeha. Ho feta moo, liboutu li tlameha ho bonts'a boima bo pakeng tsa 24 ho isa ho 35 HRC (Rockwell C scale) ho netefatsa hore ha li brittle kapa bonolo haholo.

**Teko le Setifikeiti:**
Ho etsa bonnete ba ho tsamaellana le litlhokahalo tsena, liboutu tsa A325M li etsa liteko tse matla, ho kenyeletsoa tlhahlobo e thata, tlhahlobo ea boima ba 'mele le tlhahlobo ea phello. Baetsi ba tlameha ho fana ka setifikeiti sa hore liboutu li kopana le litekanyetso tse boletsoeng tsa thepa le thepa ea mochini. Setifikeiti sena se bohlokoa bakeng sa netefatso ea boleng mme hangata se hlokoa ke likhoutu le litekanyetso tsa kaho.

Qetellong, A325Mliboutu tse boima tsa hexli entsoe ho fihlela litekanyetso tse phahameng tsa thepa le thepa ea mochini, ho netefatsa ts'epo le ts'ebetso ea tsona lits'ebetsong tsa meralo. Khetho e hlokolosi ea lisebelisoa, phekolo e nepahetseng ea mocheso, le mekhoa ea ho hlahloba ka ho feletseng ke tsa bohlokoa bakeng sa ho hlahisa liboutu tse ka mamellang maemo a boima a kaho ea morao-rao.

Ningbo Zhongli Bolt Manufacturing Co., Ltd. ke feme e ikhethileng e ikemiselitseng ho hlahisa boleng ba boleng bo holimo.liboutu tsa hlooho tsa hexbakeng sa mehaho ea tšepe. Ka ho hatisa ka matla taolo ea boleng, k'hamphani e iketsetse e le mofani oa thepa ea ka tšeptjoang indastering ea kaho le ea boenjiniere. Feme e sebelisa mekhoa e tsoetseng pele ea tlhahiso mme e latela litekanyetso tse thata tsa boleng ho netefatsa hore lihlahisoa tsa eona li fihlela litlhoko tse batloang ke ts'ebetso ea meralo.

Ningbo ZhongliBolt Manufacturing e sebelisana le lik'hamphani tse ngata tsa boenjiniere, ho ba fa liboutu tse tšoarellang le tse sebetsang hantle tse bohlokoa bakeng sa merero ea kaho e bolokehileng le e tšepahalang. Boitlamo ba bona ba bokhabane le khotsofalo ea bareki bo entse hore ba be le botumo bo tiileng 'marakeng. Ka ho shebana le boleng ba sehlahisoa le likamano tsa bareki, k'hamphani e ntse e tsoela pele ho bapala karolo ea bohlokoa ho ts'ehetsa nts'etsopele ea lits'ebetso le kholo ea indasteri.
