— Isikhokelo Esipheleleyo kwiMigangatho yeMbhobho engenamthungo yaseRashiya eyenziwe ngoBubandayo kunye nezinto ezisetyenzisiweyo
Umbhobho weSanon – Umboneleli wakho othembekileyo weetyhubhu zentsimbi ezichanekileyo ezihambelana ne-GOST
1. Isishwankathelo seNkqubo eQhelekileyo: Ubudlelwane obuQhelekileyo phakathi kweGOST 8734 kunye neGOST 8733
I-GOST 8734-75 ngumgangatho omiselweyo/ohlukeneyo weemibhobho zentsimbi ezingenamthungo ezenziwe ngokubandayo (ezitsalwa ngokubandayo/eziqengqelekayo) eRashiya (eyayisakuba yi-USSR). Icacisa uluhlu lwangaphandle lobubanzi, uthotho lobukhulu bodonga, ukunyamezelana kobukhulu, iintlobo zobude kunye nokuphambuka okuvumelekileyo, kunye nobunzima bethiyori yeemibhobho. Inkqubo yokutsala okubandayo ifikelela kuchanekileyo oluphezulu kakhulu kunemibhobho eqengqelekayo eshushu, okwenza kube lukhetho olufanelekileyo lwezixhobo ezichanekileyo, iinkqubo ze-hydraulic, izakhiwo zoomatshini ezichanekileyo kakhulu, kunye nokusetyenziswa okufanayo.
Kwinkqubo yemigangatho yaseRashiya, iGOST 8734-75 kufuneka isetyenziswe kunye neemeko zobugcisa ezihambisana nayo ezisemgangathweni iGOST 8733-87. Ngokwenyani, iGOST 8734-75 ichaza "indlela ebonakala ngayo ipayipi" (ubukhulu kunye nokunyamezelana), ngelixa iGOST 8733-87 ichaza "ukuba yintoni na into esetyenziswayo kunye nokuba inamandla kangakanani" (ukwakheka kunye nokusebenza kwayo).

|---|---|---|
| I-GOST 8733-87 | Imibhobho yentsimbi engenamthungo eyenziwe ngokubandayo – Iimeko zobugcisa | Amanqanaba entsimbi, ukwakheka kweekhemikhali, iipropati zoomatshini, uvavanyo lwenkqubo, uvavanyo lwe-hydrostatic, imithetho yokuhlola, ukumakisha, ukupakisha |
| I-GOST 8734-75 | Imibhobho yentsimbi engenamthungo eyenziwe ngobandayo – Uluhlu olunemilinganiselo | Uluhlu lobubanzi bangaphandle, uthotho lobukhulu bodonga, ukunyamezelana okulinganayo, iintlobo zobude kunye nokuphambuka okuvumelekileyo, ubunzima bethiyori |
Icebiso lokuThenga: Kumaxwebhu obunjineli okanye kwii-odolo zokuthenga, i-GOST 8733 kunye ne-GOST 8734 phantse zihlala zikhankanywa kunye; zenza umgangatho opheleleyo wemveliso yombhobho.
2. Inkcazo eneenkcukacha zezinto ezisetyenzisiweyo: Intsimbi 20 (iBanga 20)
Intsimbi 20 (igama lesiRashiya elithi Ст20) yeyona ntsimbi yesakhiwo yekhabhoni esemgangathweni esetyenziswa kakhulu phantsi komgangatho weGOST 8734, enika indibaniselwano efanelekileyo yeempawu. Ngokungafaniyo nentsimbi eqengqelekayo eshushu engama-20 kwiGOST 8731, intsimbi ebanda etsalwa yintsimbi 20 inika ukuchaneka okuphezulu kunye nomgangatho womphezulu.
