Porogaramu
Udupira tw'ibishushanyo:
Imashini zikata uduce tw’uburinzi zifite ibyuma byo gukata amabuye cyangwa ubutaka munsi y’ubutaka. Izi mashini zisanzwe zikozwe mu byuma bikomeye bitewe n’ubukana bwazo bwiza no kudashira, bigatuma zikora neza mu bihe bigoye munsi y’ubutaka.
Udukingirizo twa Disiki ya Shield TBM:
Uduce twa disiki ya Shield TBM ni ingenzi cyane dushyigikira kandi tugayobora umutwe w’icyuma gikata, bigatuma inzira yo gukata igenda neza. Uduce twa disiki kandi dukeneye ubushobozi bwo kudashira no kudashwanyagurika, ibyo aloyi ishobora gutanga.
Intebe zo Gukata Disiki zo mu bwoko bwa Cutterhead:
Intebe zo gufata ibyuma by'icyuma bicukura mu mwanya wabyo akenshi zikoresha ibikoresho bya aluminiyumu kugira ngo icyuma gihamye kandi kirambe.
Ibikoresho byo gucukura n'ibikoreshwa mu gukata:
Mu bikorwa bimwe na bimwe byo gukata imiyoboro y'amashanyarazi, hakoreshwa uduce two gucukura n'ibindi bikoresho byo gukata. Gukora ibi bikoresho akenshi bikubiyemo ibikoresho bya alloy kugira ngo habeho ubushobozi buhagije bwo gukata no kuramba.
Ibiranga
Ubukomere:
Alloys zigaragaza ubukana budasanzwe, zikomeza gukora neza mu gukata mu gihe cy'umuvuduko mwinshi no gukururana, bityo zikongera igihe cyo kubaho cy'ibikoresho.
Ubudahangarwa ku kwambara:
Gukata amabuye yo munsi y'ubutaka n'ubutaka bikoresha ibikoresho byangiritse cyane. Ubudahangarwa bw'ibyuma bya aluloyi butuma ibyuma n'ibikoresho byo gukata bikomeza gukora neza mu bidukikije bikomeye.
Ubudahangarwa ku ngaruka:
Imashini zikoresha ibyuma byo mu bwoko bwa "shield tunnel" zishobora guhura n'ubushuhe, ibintu byangiza, n'ibindi bintu biri munsi y'ubutaka. Ubudahangarwa bwa "Alloys" mu kwangiza bufasha mu kurinda ibikoresho kwangirika.
Guhagarara neza k'ubushyuhe:
Mu gihe cyo gucukura imiyoboro y'amazi, ibikoresho bitanga ubushyuhe bitewe no gukururana. Ubusanzwe, imiyoboro y'amazi ifite ubushyuhe buhamye, ikomeza gukora neza ndetse no mu gihe cy'ubushyuhe bwinshi.
Imbaraga:
Muri rusange, aluminiyumu zifite imbaraga nyinshi, ibyo bikaba ari ingenzi cyane mu kwihanganira imbaraga zo gukata no gukubita.
Muri make, alloys zigira uruhare runini mu ikoreshwa ry’imashini zikora imiyoboro y’uburinzi, zitanga imiterere nko kudasaza, kudahura n’ingufu, no gukomera cyane kugira ngo zikore neza mu bidukikije bigoye munsi y’ubutaka. Ubwoko butandukanye bw’alloys bukoreshwa hashingiwe ku bisabwa mu buhanga n’imiterere y’ibikoresho byihariye.
Amakuru y'Ibikoresho
| Amanota | Ubucucike (g/cm³)±0.1 | Ubukomere (HRA)±1.0 | Cobalt (%) ± 0.5 | TRS (MPa) | Porogaramu Isabwa |
| KD402C | 14.15-14.5 | ≥87.5 | ≥2600 | Imiterere itandukanye y’ubutaka n’imishinga y’ubuhanga. Igaragaza imikorere myiza cyane mu bijyanye n’ubukomere, kudasaza, imbaraga, kudasaza, no kudahinduka kw’ubushyuhe |
Kimberly Carbide ikoresha ibikoresho bigezweho by’inganda, uburyo bwo gucunga buhanitse, n’ubushobozi budasanzwe bwo guha abakiriya bo ku isi yose ubuhanga bukomeye mu ikoranabuhanga n’uburyo burambuye bwa VIK. Ibicuruzwa byizewe mu bwiza kandi bigaragaza imikorere myiza, biherekejwe n’imbaraga zikomeye mu ikoranabuhanga zidasanzwe zidafite bagenzi babo. Iyi sosiyete ishoboye gukora ibicuruzwa bishingiye ku byo abakiriya bakeneye, ndetse no kunoza no kuyobora tekiniki buri gihe.
