Ubulukhuni bombhobho wentsimbi bubhekisa kubuchule bokwenyama ukumelana nengxaki phantsi kwamandla angaphandle. Ubunzima yenye yezona zinto zibalulekileyo zentsebenzo yokwenyama.
Kwimveliso kunye nokusetyenziswa kwemibhobho yentsimbi, ukumiselwa kobunzima babo kubaluleke kakhulu. Ubulukhuni bemibhobho yentsimbi inokulinganiswa ngobunzima obuninzi obufana ne-rockwell, i-brinell, kunye nabavukeli eveliswe nguLaizhou I-Laihua yokuvavanya isixhobo, esinokwenziwa ngokwezifiso njengoko kufuneka. Iindlela eziphambili zokulinganisa zibandakanya oku kulandelayo:
I-1. Indlela yovavanyo lwe-rockwell
Uvavanyo lwe-rockweol kungoku lwangoku luhlobo lwendlela esetyenzisiweyo, phakathi kwe-HRC ikwisibini kuphela kwi-Brinell Hb kumgangatho wentsimbi. Ilinganisa ubunzulu be-induction kwaye inokusetyenziselwa ukulinganisa izixhobo zentsimbi zithambile kakhulu kuba nzima kakhulu. Ilula kunendlela yeBrinell.
2. Indlela yokuvavanya i-brinell
Indlela yokuvavanya ibrinell yovavanyo isetyenziswa ngokubanzi kwicandelo lemizi-mveliso. Isetyenziswe ngokubanzi kwimigangatho yentsimbi engenayo. Ubulukhuni bezinto ezibonakalayo zibonakala zibonakaliswa yidayitha yohlobo lwendalo. Kuyinto emnandi kwaye ilungele, kodwa ayisebenzi kwi-pipes yentsimbi okanye emdaka.
I-3. IiNdawo zokuvavanya ubunzima
Uvavanyo lweVictors Hight lusetyenziswa ngokubanzi. Inezona zibonelelo ziphambili ze-brinell kunye neendlela zokuvavanywa kwe-robwell, kodwa zoyisa izinto zabo ezibekiweyo. Ilungele ukuvavanywa kobunzima bezixhobo ezahlukeneyo, kodwa ayifanelekanga kwiisampuli ezineedayimitha ezincinci. Ayilula njengendlela yovavanyo lwe-rockwell kwaye ayifane isetyenziswe kwimigangatho yentsimbi yentsimbi.
