Ukuqina kwepayipi lensimbi kubhekisela ekhonweni lempahla lokumelana nokuguquguquka ngaphansi kwamandla angaphandle. Ukuqina kungenye yezinkomba ezibalulekile zokusebenza kwempahla.
Ekukhiqizeni nasekusetshenzisweni kwamapayipi ensimbi, ukuzimisela kokuqina kwabo kubaluleke kakhulu. Ukuqina kwamapayipi ensimbi kungakalwa ngabahloli bokuqina abahlukahlukene njenge-Rockwell, i-Brinell, ne-Vickers ekhiqizwe yi-Laizhou Laihua Testing Instrument Factory, engenziwa ngendlela oyifisayo njengoba kudingeka. Izindlela zokulinganisa eziyinhloko zihlanganisa lezi ezilandelayo:
1. Indlela yokuhlola ubulukhuni be-Rockwell
Ukuhlolwa kokuqina kwe-Rockwell okwamanje kuyindlela esetshenziswa kakhulu, phakathi kwayo i-HRC ingeyesibili kuphela ku-Brinell hardness HB kuzinga lepayipi lensimbi. Ikala ukujula kokuhlehlisa futhi ingasetshenziswa ukukala izinto zensimbi ukusuka ekuthambile kakhulu kuye kokuqina ngokwedlulele. Ilula kunendlela yokuhlola i-Brinell.
2. Indlela yokuhlola ubulukhuni beBrinell
Indlela yokuhlola ubulukhuni beBrinell nayo isetshenziswa kabanzi emkhakheni wezimboni. Isetshenziswa kabanzi kumazinga wepayipi lensimbi engenamthungo. Ukuqina kwento kuvame ukuvezwa yi-diameter ye-indentation. Kuyaqondakala futhi kulula, kodwa akusebenzi kumapayipi ensimbi aqinile noma amancanyana.
3. Indlela yokuhlola ubulukhuni beVickers
Isivivinyo sokuqina kweVickers sisetshenziswa kabanzi. Inezinzuzo eziyinhloko zezindlela zokuhlola i-Brinell ne-Rockwell, kodwa inqoba ukuntula kwayo okuyisisekelo. Ifanele ukuhlolwa kobulukhuni bezinto ezihlukahlukene, kodwa ayifanele amasampula anama-diameter amancane. Ayilula njengendlela yokuhlola ye-Rockwell futhi ayivamisile ukusetshenziswa ezindinganisweni zamapayipi ensimbi.
