Ijija ezenziwe ngentsimbi: iintlobo kunye nemida yayo

Ngexesha uyilo kunye nolwakhiwo kweenkqubo yemibhobho ingqalelo eyodwa ihlawulwe neneenkcukacha kunye namalungu ingenamthungo kwimibhobho ngobubanzi ezahlukeneyo. Kumacandelo kugunyaziso kusetyenziswa ezimbaxa, ekuthiwa ngentsimbi lotshintsho nangokuvumela flow simahla yokusingqongileyo yokusebenza kumacala omabini. Le nto kwiimeko ezininzi ethandwa kakhulu. abenzi Russian ukuvelisa utshintsho intsimbi eqhelekileyo ngokungqinelana ne-GOST 17378-2001 kunye zinakho ezizodwa esalo kwi amalunga ayikho parameters emgangathweni efanelekileyo. Kukho iindidi ezimbini semigudu lalisetyenziswa imibhobho efakwe: ome kunye concentric.

Kwimeko yokuqala, ugwebu shift kunye umzali ithuba umgca flow fluid yi imali encinane, nto leyo usenako nefuthe ukuhamba kwezithuthi. Apha, i ephantsi iba indawo lonxibelelwano.

Kwimeko yesibini, ngentsimbi utshintsho ngemibhobho concentric kunceda amalungu ngelotha ngaphandle ukubana ecaleni ezimanyeneyo indlela yokusebenza.

Flow edlula kwindawo evulekileyo mbhobho ngexesha lekhefu, ukunyuka okanye kuyancipha, ngokunjalo uxinzelelo lomsebenzi. Le nkqubo kuxhomekeke utshintsho kwensimbi.

Izinto malunga nokuveliswa kwemithambo yi kumabakala ngentsimbi ezahlukeneyo. Kuba ukusebenza kohlelo zentsimbi bume xi eliphantsi non-onakalisayo zenziwa carbon sentsimbi St3, St10, St20. Ezi mveliso ezikhutshwe ukususela kumabanga intsimbi ezifana 12X18H10T, 15X5M isicelo xa ezithutha ndlongondlongo ulwelo flow, xa sisincoko intsimbi ezizodwa zongezwa ukuphucula nokumelana elide. Ngensimbi nge umhlwa ephantsi utshintsho ukuxhathisa ukuvelisa kuhlinzwa yayisoma zinc kwi umaleko omnye.

Into ebalulekileyo unyanzeliso na uxinzelelo yokusebenza ubuninzi ngokuxhomekeke eziphathekayo zejometri iparameters ukumelana uxinzelelo yokusebenza kuluhlu ka-4 ukuya 160 MPA, ehambisana avumelekile ubuninzi.

Utshintsho kumandla steel welding, yenzelwe ukusebenza noxinzelelo-16 MPA nokuxhatshazwa kwiqondo lobushushu ukusuka -70 ukuya + 450 ° C, kwaye abanganyangekiyo lobushushu kunye noxinzelelo umahluko.
Ithekhnoloji imveliso ekhoyo ukuvelisa indlela rebar of ukutshayela okanye ilahle electroslag centrifugal, naye ngalo kweziphazamiso, ukwandisa ukuthembeka kunye nobomi nkonzo.

Iimfuno imiyalelo izinto ezingafanelekileyo kunye nebandla:

- ngentsimbi kufuneka ductility eliphezulu, isakhiwo svarimostyu kunye kobulembu ;

- imingxuma ukuthobela ukulingana lotshintsho nogwali ubungqukuva kunye nesiphelo moya ubuso.

Ukukhetha utshintsho ensimbi, kumele ukuba zichithe ezi khrayitheriya zilandelayo:

- owongozelelweyo iplagi umbhobho;

- uhlobo lwezinto kunye neempawu zayo amandla;

- Ukujonga eliphakathi ukusebenza kunye umahluko ubushushu;

- kontanga Operating.
