Kutshanje, iqela elitsha leIityhubhu zentsimbi ezingenamthungo ze-DIN 2391 St52 ezitsalwe ngokubandayoeIndiya igqityiwe ngempumelelo. Ngaphambi kokuthunyelwa,Intsimbi yeBotopyenze uhlolo olungqongqo lobukhulu ukuqinisekisa ukuba imveliso iyahlangabezana ngokupheleleyo neemfuno zobugcisa zomthengi kunye nemigangatho yokuchaneka (iifoto zohlolo ziqhotyoshelwe ekupheleni kwenqaku).
Iityhubhu zentsimbi echanekileyo ziityhubhu zentsimbi ezinomlinganiselo oqinileyo kunye nomgangatho ophezulu womphezulu, ezisetyenziswa kakhulu kwizixhobo ze-hydraulic, iinkqubo zomoya, iindawo zezithuthi kunye nezinye izicelo ezifuna ukuchaneka okuphezulu.
Imigangatho esetyenziswa rhoqo kwiityhubhu zentsimbi ezichanekileyo ezingenamthungo ibandakanyaI-DIN 2391, EN 10305-1kunyeGB/T 3639Phakathi kwazo, i-DIN 2391 St52 ludidi olusetyenziswa kakhulu, olwaziwa ngeempawu zalo ezilungileyo zoomatshini kunye nokusebenza kakuhle koomatshini.
Imeko yokuhanjiswa yinto ebalulekileyo echaphazela ukusebenza kweetyhubhu zentsimbi ezichanekileyo, njengoko ibandakanya iinkqubo ezahlukeneyo zonyango lobushushu ezisetyenziswa kwiityhubhu.
| I-DIN 2391 | I-EN 10305-1 kunye ne-GB/T 3639 | Ukutyunjwa | Inkcazo |
| BK | +C | Igqityiwe kubanda (iqinile) | Iityhubhu azinyangwa ngobushushu emva kokubanda kokugqibela, ngoko ke, zinokumelana nokuguquguquka okuphezulu. |
| BKW | +LC | Igqityiwe kubanda (ithambile) | Unyango lokugqibela lobushushu lulandelwa kukutsalwa okubandayo okubandakanya ukuguquguquka okuncinci. Ukulungiswa okufanelekileyo kuvumela inqanaba elithile lokwakheka kobanda (umz. ukugoba kwanda). |
| I-BKS | +SR | Igqityiwe kubanda kwaye ithomalalisiwe kuxinzelelo | Unyango lobushushu lusetyenziswa emva kwenkqubo yokugqibela yokwenza umkhuhlane. Ngokuxhomekeke kwiimeko ezifanelekileyo zokucubungula, ukwanda koxinzelelo olushiyekileyo olubandakanyekayo kwenza ukuba ukwenziwa kunye nokufakelwa kube kwinqanaba elithile. |
| GBK | +A | I-Annealed | Inkqubo yokugqibela yokwenza ubushushu ilandelwa kukutsalwa kwe-annealing kwindawo elawulwayo. |
| I-NBK | +N | Iqhelekile | Inkqubo yokugqibela yokwenza umkhuhlane ilandelwa kukutsalwa ngaphezulu kwendawo yokuguqula ephezulu kwindawo elawulwayo. |
Iityhubhu ze-BK (+C) kunye ne-BKW (+LC) zisebenza ngokubandayo kuphela kwaye azifuni unyango lobushushu, ngelixa ii-BKS (+SR), i-GBK (+A), kunye ne-NBK (+N) zifuna inkqubo yonyango lobushushu ehambelanayo emva kokusebenza ngokubandayo.
Kule oda, umthengi ufuna iityhubhu ezichanekileyo ze-DIN 2391 St52 ezisemgangathweni we-BK. Iimpawu zezinto ze-St52 kwiimeko ezahlukeneyo zokuhanjiswa zichazwe ngokweenkcukacha apha ngezantsi.

Le oda iqulathe iinkcukacha ezahlukeneyo, ngeli xesha sibonisa iinkcukacha zetyhubhu ene-OD 100mm × ID 80mm. Ngokutsho kwe-DIN 2391, ukunyamezelana kwe-OD kunye ne-ID kule nkcazo yi-±0.45 mm, kodwa kule meko, umthengi wayefuna inqanaba eliphezulu lokuchaneka kwaye wachaza ukunyamezelana kwe-±0.2 mm. Ukuze kuhlangatyezwane neemfuno zomthengi, iBotop Steel iphucule ngokukodwa ulawulo lokuchaneka kobukhulu bale mveliso, kwaye yahlola umbhobho ngamnye wentsimbi nganye nganye ngaphambi kokuba ithunyelwe ukuqinisekisa ukuba zonke iimfuno ziyafezekiswa.
Ezinye zeefoto zovavanyo ziqhotyoshelwe apha ngezantsi:
Uvavanyo lweDayamitha yangaphandle (OD: 80 ± 0.2 mm)
Uvavanyo lweDayamitha yangaphakathi (ID: 80 ± 0.2 mm)
Uhlolo lobude
IBotop ibisoloko ibandakanyeka kakhulu kushishino lweepayipi zentsimbi kangangeminyaka emininzi, kwaye ukugxininisa kwayo kumgangatho kunye nodumo oluhle kuye kwafumana ukuthenjwa okukhulu kwabathengi kunye nokuqatshelwa kwimarike. Ngokusebenzisana ngokusondeleyo nabathengi, inkampani iqhubeka nokuphucula iimveliso kunye neenkonzo zayo ukuze ihlangabezane neemfuno zemarike ezihlala zitshintsha.
Ukuba unayo nayiphi na imfuno yombhobho wentsimbi, ungaqhagamshelana nathi, iqela leengcali likulungele ukukunceda.
