Icyiciro cya RINA AH40 DH40 EH40 FH40 Isahani yo mu nyanja

Icyuma cyo mu nyanja bivuga ibyuma byubatswe bikoreshwa mu kubaka ubwato. Bifatwa nk'urwego rwo mu nyanja kandi rugomba kuba rushobora kurwanya ingaruka mbi zangiza ibidukikije. Kugirango ubigereho, ibintu bidasanzwe bivanga byongewe kuri aya manota murwego rwo kurinda ruswa ya agaist.Mu gihe ibyuma byinshi bya karubone bidakwiranye n’ibidukikije byo mu nyanja, hari ibyuma byinshi byo mu nyanja byo mu nyanja byemejwe n’imiryango itandukanye yo kubaka ubwato.

Ibyuma byubatswe kubwato bigabanijwemo ibyiciro byimbaraga ukurikije imbaraga zabyo nkeya: imbaraga rusange zubaka ibyuma hamwe nimbaraga zikomeye zubaka. Icyuma cya Maine bivuga icyuma gishyushye kizengurutse cyakozwe hakurikijwe ibisabwa na societe ya classique yo kubaka inyubako zubwato.

Hano ku isi hose hari societe 9 zingenzi.

RINA ni umunyamuryango washinze ishyirahamwe mpuzamahanga ry’imiryango itandukanye (IACS), ryashinzwe mu 1968. Amato ya RINA yemerwa n’abayobozi b’ibendera mpuzamahanga bagera kuri 116. Serivisi za RINA zihurijwe hamwe muburyo bwo kohereza ibicuruzwa birimo igishushanyo mbonera, inyubako, imicungire yubwato, kugenzura no kugerageza ibikoresho / ibice hamwe nubugenzuzi busanzwe kugirango ukomeze icyiciro bikoreshwa nubwikorezi, feri, ro-ro, ubwato bwabagenzi, ubwato, ubwato. , navy, LGN nibindi bikoresho byabatwara inzobere.

Icyiciro cya AH40 ibyuma ningufu zingaruka ziterwa na 0 ° C.
Icyiciro cya DH40 imbaraga zicyuma kuri -20 ° C.
Icyiciro cya EH40 imbaraga zicyuma kuri -40 ° C.
Icyiciro cya FH40 imbaraga zicyuma kuri -60 ° C.

Serivisi yo guturika
Kurasa kurasa nuburyo bukoreshwa mugusukura cyangwa gusiga ibyuma mugihe hagomba gukenerwa hejuru yubutaka. Kurasa kurasa bikoreshwa hafi yinganda zose dukorera. Cyane cyane mubwubatsi, gari ya moshi, guhimba imiterere nibindi.

Urutonde
Umubyimba: 2.5-120mm
Ubugari: 1000-3000mm
Uburebure: Nkibisabwa

Gutunganya amanota atandukanye
Icyiciro D, E (DH32, DH36, EH 32, EH 36)
Icyiciro cya D na E (harimo AH32 / 36, DH32, DH36, EH32, EH36) ibyuma byubaka ubwato bisaba ubukonje buke bwo hasi no gukora neza. Umusaruro ufite imbaraga nyinshi zubaka ibyuma byubaka bigomba kuba bisanzwe muburyo bwo kugenzura no kugenzura gukonjesha cyangwa gutunganya ubushyuhe hamwe nibikoresho byuzuye. Muri icyo gihe, ibyuma byimbere byimbere byamafaranga yatanzwe birasabwa kuba hejuru, cyane cyane ibiri muri S, P, N, 0 na H mubyuma bigomba kugenzurwa cyane.

Alloy Ibintu Byongeweho Kunoza Gukomera
Kugirango hamenyekane imikorere yicyapa gifite imbaraga nyinshi, hifashishijwe tekinoroji ya micro-alloying. Mugushyiramo Nb, V, Ti nibindi bintu bivanga mubyuma, bigahuzwa nuburyo bugenzurwa, ingano zinonosorwa kandi ubukana buratera imbere.
Icyerekezo cyiterambere cyubwato
Imbaraga nyinshi, ibisobanuro bihanitse, hamwe n’ubwato bunini n’umutekano, hamwe n’impinduka mu bisobanuro bifatika, ibisabwa ku bikoresho bisanzwe byo mu rwego rwa A bigenda bigabanuka buhoro buhoro, kandi n’ibisabwa ku mbaraga nini cyane biriyongera, bikaba byibanda mu mato manini. ya 5m z'ubugari. Isahani, uburebure bwa 200-300mm budasanzwe bwubwato.
