Indlela yokugcina izixhobo ze-bolt eziphezulu?

Iibholiti zamandla aphezulu njenge 12.9 bolt, 10.9 bolt, 8.8 bolt

1 Iimfuno zobugcisa zeumgangatho ophezulu weebholithi

I-1) Iibholithi eziphakamileyo kufuneka zihlangabezane nezi nkcukacha zilandelayo:

Iimpawu zobugcisa beebholiti eziphezulu kufuneka zihlangabezane neemfuno ezifanelekileyoI-ASTM A325 bolt yesakhiwo sentsimbiamabakala kunye neentlobo, i-ASTM F436 i-hardened washers yentsimbi, kunye ne-ASTM A563 nuts.

2) Ukongeza kokuhlangabezana nemigangatho ye-ASTM A325 kunye ne-ASTM A307, i-geometry ye-bolt kufuneka iphinde ihlangabezane neemfuno ze-B18.2.1 kwi-ANSI. Ukongeza kokuhlangabezana nemigangatho ye-ASTMA 563, amantongomane kufuneka ahlangabezane neemfuno ze-ANSI B18.2.2.

I-3) Ababoneleli baqinisekisa iibholiti eziphezulu, amantongomane, ama-washers kunye nezinye iindawo zokudibanisa ukuqinisa ukuqinisekisa ukuba iibholiti eziza kusetyenziswa zichongiwe kwaye zihlangabezane neemfuno ezisebenzayo ze-ASTM. Iibholiti eziphakamileyo eziphezulu zihlanganiswe ngumenzi kwiibhetshi Ukubonelela, umenzi kufuneka anike isiqinisekiso somgangatho wemveliso kwibhetshi nganye.

4) Umthengisi kufuneka abonelele ngamantongomane afakwe i-lubricated avavanyiwe kunye neebholiti eziphezulu ezinikezelweyo.

2. iibholiti zamandla aphezulu kwisakhiwo sentsimbiUkugcinwa kweebholithi

1) Iibholiti eziphezulukufuneka ingabinamvula, ikhuseleke ukufuma, kwaye itywinwe ngexesha lokuthuthwa kunye nokugcinwa, kwaye kufuneka ifakwe kwaye ithulwe kancinci ukukhusela umonakalo kwimicu.

I-2) Emva kokuba iibholiti eziphezulu zingena kwisayithi, kufuneka zihlolwe ngokwemigaqo. Kuphela emva kokuphumelela ukuhlolwa kunokufakwa kwi-inventory kwaye isetyenziswe kwimveliso.

3) Ibhetshi nganye yeiibholiti eziphezulukufuneka ube nesiqinisekiso somzi-mveliso. Ngaphambi kokuba iibholithi zifakwe kwindawo yokugcina, ibhetshi nganye yeebholiti kufuneka ithathwe iisampulu kwaye ihlolwe. Xa iibholiti zomelele kakhulu zibekwe kwindawo yokugcina, umenzi, ubungakanani, uphawu, uhlobo, iinkcukacha, njl.njl. kufuneka zitshekishwe, kwaye inombolo yebhetshi kunye neenkcukacha (eziphawulweyo (ubude kunye nobubanzi) zigcinwa ngokweseti ezipheleleyo, kwaye zikhuselwe ngokuchaseneyo. umswakama kunye nothuli ngexesha lokugcinwa ukuze kuthintelwe ukubola kunye nokutshintsha kwemeko yendawo, ukugcinwa okuvulekileyo kunqatshelwe ngokungqongqo.

I-4) Iibhotshi eziphezulu kufuneka zigcinwe kwiindidi ngokwenombolo yebhetshi kunye neenkcukacha eziboniswe kwibhokisi yokupakisha. Kufuneka zigcinwe kwindawo yokugcina phezulu ngaphakathi endlwini kwaye akufanele zipakishwe ngaphezu kweeleya ezintlanu. Musa ukuyivula ibhokisi ngokuthanda kwakho ngexesha lokugcinwa ukuze uthintele ukurusa kunye nokungcoliseka.

5) Kwindawo yokufakela, iibholiti kufuneka zifakwe kwisitya esitywiniweyo ukuphepha impembelelo yothuli kunye nomswakama. Iibholiti ezinerusi kunye nothuli oluqokelelweyo aziyi kusetyenziswa ekwakhiweni ngaphandle kokuba zifanelekile ngokuhambelana ne-ASTM F1852.
