Uboniso oluthile lweemveliso zenkampani

Ngophuhliso lwezenzululwazi kunye netekhnoloji, ukusetyenziswa kwesakhiwo sentsimbi kubunjineli bokwakha ngakumbi nangakumbi kwihlabathi. I-Welding yitekhnoloji yokulungisa ebaluleke kakhulu kulwakhiwo lwentsimbi. Ngokwezibalo zamazwe aphuhlisiweyo kwimizi-mveliso, kuphela isinyithi esisetyenzisiweyo emva kwentsimbi sithatha malunga neepesenti ezingama-45 zemveliso yentsimbi minyaka yonke. China ukuya ekupheleni kweminyaka yama-1980 ine-30% yemveliso yentsimbi.

Ngowe-1992, imveliso yentsimbi yaseTshayina yayiziitoni ezingama-80 ezigidi, kodwa ukuphela kuka-1997, imveliso yentsimbi yaseTshayina yayisele ifikelele kwizigidi ezingama-94 zeetoni. Ngokwendlela yophuhliso, imveliso yentsimbi yase China kungekudala iza kutyhoboza i-100 yezigidi zeetoni emva kokungena kwinkulungwane entsha.

Iimpawu zesakhiwo sentsimbi:

Isinyithi esiqengqelekayo esishushu (i-Angle steel, i-i-steel, ishaneli yentsimbi, ityhubhu yentsimbi, njl.njl., Ukwenziwa kwensimbi yodonga olucekeceke, ipleyiti yesinyithi, intambo ebandayo kunye nentambo njengomba osisiseko, nge-welding, bolt okanye rivet uqhagamshelo, ngokwe imigaqo ethile yokuqhagamshela kwiibhloko zokwakha ezisisiseko, ezingagunyaziswanga nge-welding, i-bolt okanye i-rivet uqhagamshelo oludibanisa iibhloko zokwakha ezisisiseko kulwakhiwo njengesakhiwo sentsimbi ukumelana nomthwalo.

Amandla esinyithi aphakamileyo amaxesha amaninzi kunalawo omthi, izitena kunye nelitye, ikhonkrithi kunye nezinye izinto zokwakha. Ke ngoko, xa umthwalo kunye neemeko zinye, isakhiwo esenziwe ngentsimbi sinobunzima obuncinci bokufa, amacandelo amancinci afunekayo, kwaye kulula ngakumbi ukuthuthwa kunye nolwakhiwo.

(2) Iplastikhi elungileyo kunye nobukrakra.Steel sineplastikhi elungileyo, ngokubanzi, ayisayi kuba ngenxa yokugcwala okungaphezulu ngengozi okanye ukulayishwa okungaphezulu kwendawo okubangelwa kukungaphumeleli kokuqhekeka ngesiquphe, kodwa kuya kuvela ngaphambi kohlengahlengiso olukhulu lwe-omen, ukuze kuthathwe amanyathelo okulungisa Isinyithi sikwanobungqingqwa obuhle kunye nokuziqhelanisa okunamandla nomthwalo onamandla osebenza kulwakhiwo, olunika isiqinisekiso esithembakeleyo sokusetyenziswa okukhuselekileyo kwesakhiwo sensimbi.

Uyilo lwangaphakathi lwentsimbi luyinto efanayo, iipropathi ezibonakalayo kunye noomatshini bazo zonke iindlela ziyafana, zisondele kakhulu kumzimba we-isotropic, ngaphakathi kuluhlu oluthile loxinzelelo, isinyithi esikwimeko efanelekileyo yokuthamba, kunye nesiseko Ingqikelelo esetyenziswe ngoomatshini bobunjineli iyahambelana ngakumbi, ke iziphumo zokubala zichanekile kwaye zithembekile.

Isakhiwo sentsimbi senziwe ngamacandelo aqhubekekayo kunye neepleyiti zensimbi, ezenziwa zenziwa ngendlela esisiseko ngokudibanisa, i-bolt okanye uqhagamshelo lwe-rivet, emva koko zithunyelwa kwindawo yokuhlanganisana kunye nokucoca. Umjikelo wesicelo mfutshane, ukusebenza kakuhle kuphezulu, kwaye ukulungiswa, ukutshintshwa kwakhona kukwalula.Le ndlela yokwakha yokuvelisa imveliso kunye nokufakwa kwesiza kunezibonelelo zemveliso enkulu yebhetshi kunye nokuchaneka okuphezulu kweemveliso ezigqityiweyo, kwaye kudale iimeko zokunciphisa iindleko kunye nokuzisa kumdlalo izibonelelo zoqoqosho zotyalo mali

(5) Poor umhlwa ukumelana phezulu.

Iqondo eliphantsi lobushushu ukumelana.Steel alixhathisi kubushushu obuphezulu, ngokunyuka kweqondo lobushushu, amandla esinyithi aya kuncipha.Mlilweni, isakhiwo sesinyithi ngaphandle kokhuseleko sinokugcinwa kuphela malunga ne-20min, ke ngoko kubalulekile ukwakhiwa kwesinyithi. thatha amanyathelo okuthintela umlilo, njengakwisakhiwo sesinyithi ngaphandle kwesonka sekhonkrithi okanye ezinye izinto zomlilo, okanye ukutshiza ukutshiza umlilo kumphezulu wezinto.

Umboniso weemveliso ezigqityiweyo ngaphambi kokupeyinta kugqityiwe ngokwenani lokuzoba. Inani libonisa ukuba iinxalenye ezingapeyintwanga zisiwe ngokolandelelwano lwamanani, nokuba ungahamba okanye ufakelo
