Ukuqina kombhobho wentsimbi kubhekisa kubuchule bezinto ezisetyenziswayo bokumelana nokuguquguquka phantsi kwamandla angaphandle. Ukuqina ngomnye wemiqondiso ebalulekileyo yokusebenza kwezinto.
Kwimveliso nokusetyenziswa kwemibhobho yentsimbi, ukuchonga ubulukhuni bayo kubaluleke kakhulu. Ubulukhuni beemibhobho zentsimbi bungalinganiswa ngabavavanyi bobulukhuni abahlukeneyo abanjengoRockwell, Brinell, kunye noVickers abaveliswe yiLaizhou Laihua Testing Instrument Factory, abanokwenziwa ngokwezifiso njengoko kufuneka. Iindlela eziphambili zokulinganisa ziquka oku kulandelayo:
1. Indlela yokuvavanya ubulukhuni bukaRockwell
Uvavanyo lokuqina kweRockwell yeyona ndlela isetyenziswa kakhulu okwangoku, apho i-HRC ilandela kuphela i-Brinell hardness HB kumgangatho wepayipi yentsimbi. Ilinganisa ubunzulu bokutsalwa kwaye ingasetyenziselwa ukulinganisa izinto zesinyithi ukusuka ekuthambileni kakhulu ukuya ekuqineni kakhulu. Ilula kunendlela yokuvavanya iBrinell.
2. Indlela yokuvavanya ubulukhuni bukaBrinell
Indlela yokuvavanya ubulukhuni beBrinell ikwasetyenziswa kakhulu kwicandelo lemizi-mveliso. Isetyenziswa kakhulu kwimigangatho yemibhobho yentsimbi engenamthungo. Ubulukhuni bezinto budla ngokubonakaliswa bububanzi bokutsalwa. Iyaqondakala kwaye ilula, kodwa ayisebenzi kwimibhobho yentsimbi eqinileyo okanye ebhityileyo.
3. Indlela yokuvavanya ubulukhuni beVickers
Uvavanyo lokuqina lweVickers nalo lusetyenziswa kakhulu. Lunezibonelelo eziphambili zeendlela zovavanyo lweBrinell nolweRockwell, kodwa luyawoyisa amaphutha azo asisiseko. Lufanelekile kuvavanyo lokuqina kwezinto ezahlukeneyo, kodwa alufanelekanga kwiisampuli ezinobubanzi obuncinci. Alulula njengendlela yovavanyo lweRockwell kwaye alusetyenziswa rhoqo kwimigangatho yemibhobho yentsimbi.
