1. Intshayelelo Jikelele

I-EN 10305-5 licandelo elizinikeleyo kuluhlu oluqhelekileyo lweetyhubhu zentsimbi echanekileyo yaseYurophu. Isihloko sayo esipheleleyo sithi "iityhubhu zentsimbi echanekileyo—Icandelo lesi-5: Iimeko zobuchwephesha zokuhanjiswa kweetyhubhu zesinyithi ezisikwere nezingxande ezigqityiweyo kubanda." Lo mgangatho uphuhliswa yiKomiti yaseYurophu yoKulinganisa (i-CEN) kwaye usebenza njengenye yeendlela eziphambili zobugcisa zokuvelisa nokwamkelwa kweetyhubhu zesinyithi ezimile okwesicaba kulo lonke elase-EU.

 Lo mgangatho usebenza kwiityhubhu zesikwere nezingxande ezigqityiweyo kubanda ezinobukhulu bodonga obuyi-6mm kunye nobubanzi obuncinci bangaphandle obuyi-4mm. Ezi mveliso zibonakaliswa kukuchaneka okuphezulu, umgangatho ophezulu womphezulu, kunye neempawu ezihambelanayo zoomatshini, ezizibeka njengeemveliso zeetyhubhu zentsimbi ezinexabiso eliphezulu.

 2. Iimfuno zobuGcisa eziPhambili

2.3 Iipropati zoomatshini (E235 njengeReferensi)

 Amandla okuThamba: 440-540 MPa

 Unikeze Amandla:≥290 MPa

 Ukwandiswa kwepesenti:≥12%

 2.4 Iimeko zokuhanjiswa

 Lo mgangatho uvumela iimeko ezininzi zokuhanjiswa, kuxhomekeke kwisivumelwano phakathi komthengisi kunye nomthengi:

 I-BK (iqinileyo egqityiweyo ngokubandayo): Ibonelelwa ngaphandle konyango lobushushu, igcina imeko enzima emva kokusebenza ngokubandayo

 I-BKW (Isebenza kancinci kubanda): Ukusebenza kubanda okuncinci kodwa okuhlala kumile kakuhle

 I-GBK (i-Annealed): I-Annealed emva kokusebenza ngokubandayo

 I-NBK (Eqhelekileyo): Ibonelelwa kwimeko eqhelekileyo

 3. Iimarike zezicelo

Iityhubhu zentsimbi ze-EN 10305-5 zisetyenziswa kakhulu kwizicelo zokwenziwa ngokuchanekileyo. Ukusetyenziswa okuqhelekileyo kuquka:

 Iinkqubo zoThutho lweHydraulic: Iisekethe zeoyile zeHydraulic kwiimashini zokwakha nezixhobo zoomatshini, ezifuna ubungakanani obuchanekileyo kunye nemiphezulu yangaphakathi egudileyo ukuqinisekisa ukusebenza kakuhle kothutho lwefluid.

 Iinkqubo zoLawulo lwe-Pneumatic: Imigca yokuhambisa umoya ecinezelweyo eneemfuno ezingqongqo zokuvala ngokuchanekileyo ukulingana.

 Ukwenziwa kweCandelo leeMoto: Imigca yokufaka uphethiloli enoxinzelelo oluphezulu kunye nemibhobho yenkqubo yokuqhuba ngamandla—zombini izinto ezibalulekileyo zokhuseleko.

 Umatshini Oqhelekileyo: Usetyenziswa njengeendawo ezingenanto kwiisleeve zeshaft ezichanekileyo, iisleeve zesikhokelo, kunye neenkxaso zesakhiwo kwimisebenzi elandelayo yoomatshini.

 Ukuhlanganiswa kwezixhobo zoShishino: Ii-sensor sleeves, ii-instrumentation tubes, kunye nezinye iindlela ezifanayo zokuchaneka.

 4. Amashishini afanelekileyo

Iimveliso eziphantsi kwe-EN 10305-5 ngokuyintloko zinceda la macandelo alandelayo emizi-mveliso:

Ukuveliswa kwezithuthi zeemoto nezorhwebo

Oomatshini Bokwakha Nezixhobo Zolimo

Ukuveliswa kweCandelo leHydraulic kunye nePneumatic

Izixhobo eziBanzi kunye neMishini echanekileyo

Ukuhlanganiswa kweMizi-mveliso yokuZenzekela kunye neeNkqubo zoLawulo

5. Indawo yeMarike kunye neXabiso

I-EN 10305-5 ayiweli kudidi lweetyhubhu zesakhiwo ngokubanzi. Endaweni yoko, ijolise kwimarike yeetyhubhu zentsimbi ezikhethekileyo ezichanekileyo, ezithembekileyo kakhulu, kunye nexabiso eliphezulu. Amaxabiso ayo aphambili aquka:

Ukubonelela abathengi ngeempawu zokusebenza ezinokuqikelelwa nezingqinisisekayo

Ukunciphisa inkunkuma yezinto eziphathekayo kunye neendleko zokulungisa ngokutsha kubathengi abasezantsi ngexesha leenkqubo zoomatshini kunye nokuhlanganiswa

Ukuqinisekisa ukusebenza okuzinzileyo kwexesha elide kwezixhobo zokusetyenziswa kokugqibela phantsi kweemeko zokusebenza ezixinzelelweyo nezisebenza ngexesha eliphezulu

Kwabathumeli beetyhubhu zentsimbi baseTshayina, i-EN 10305-5 yenye yemigangatho eqhelekileyo yokufikelela kwikhonkco lokubonelela ngemveliso echanekileyo yaseYurophu. Amandla abonakalisiweyo okubonelela ngeemveliso ngokuhambelana nalo mgangatho asebenza njengesiqinisekiso esibalulekileyo sokufumana ukuqatshelwa ngabathengi baseYurophu abaphakathi ukuya kwabaphezulu kwiinxalenye zeemoto, iinkqubo ze-hydraulic, kunye namacandelo anxulumene noko.
