Ubulukhuni bepayipi lensimbi bubhekisela ekhonweni lento yokumelana nokuguquguquka ngaphansi kwamandla angaphandle. Ubulukhuni bungenye yezinkomba ezibalulekile zokusebenza kwezinto.
Ekukhiqizweni nasekusetshenzisweni kwamapayipi ensimbi, ukunqunywa kobulukhuni bawo kubaluleke kakhulu. Ubulukhuni bamapayipi ensimbi bungalinganiswa ngabahloli bobulukhuni abahlukahlukene njengeRockwell, Brinell, kanye neVickers abakhiqizwe yiLaizhou Laihua Testing Instrument Factory, abangenziwa ngokwezifiso njengoba kudingeka. Izindlela eziyinhloko zokulinganisa zifaka okulandelayo:
1. Indlela yokuhlola ubulukhuni beRockwell
Ukuhlolwa kobulukhuni beRockwell okwamanje kuyindlela esetshenziswa kakhulu, phakathi kwayo i-HRC ingeyesibili kuphela emva kwe-Brinell hardness HB ejwayelekile yepayipi lensimbi. Ilinganisa ukujula kokugoba futhi ingasetshenziswa ukukala izinto zensimbi kusukela ekuthambekeni kakhulu kuya ekuqineni kakhulu. Kulula kunendlela yokuhlola yeBrinell.
2. Indlela yokuhlola ubulukhuni bukaBrinell
Indlela yokuhlola ubulukhuni beBrinell isetshenziswa kabanzi emkhakheni wezimboni. Isetshenziswa kabanzi ezindinganisweni zamapayipi ensimbi angenamthungo. Ubulukhuni bezinto ezibonakalayo buvame ukubonakaliswa ububanzi bokugoba. Iyaqondakala futhi ilula, kodwa ayisebenzi kumapayipi ensimbi aqinile noma amancane.
3. Indlela yokuhlola ubulukhuni be-Vickers
Ukuhlolwa kobulukhuni be-Vickers nakho kusetshenziswa kabanzi. Kunezinzuzo eziyinhloko zezindlela zokuhlola ze-Brinell ne-Rockwell, kodwa kuyanqoba ukushiyeka kwazo okuyisisekelo. Kufanelekile ukuhlolwa kobulukhuni bezinto ezahlukahlukene, kodwa akufanele amasampula anobubanzi obuncane. Akulula njengendlela yokuhlola ye-Rockwell futhi akuvamile ukusetshenziswa ezindinganisweni zamapayipi ensimbi.
