1) Ingabe i-Rockwell hardness tester ingasetshenziselwa ukuhlola ubulukhuni bodonga lwamapayipi ensimbi?
Impahla yokuhlola iyipayipi lensimbi le-SA-213M T22 elinobubanzi obungaphandle obungu-16mm nogqinsi oluyi-1.65mm. Imiphumela yokuhlolwa kokuqina kokuqina kwe-Rockwell imi kanje: Ngemva kokukhipha isikali se-oxide kanye nongqimba lwe-decarburization ebusweni besampula ngomshini wokugaya, isampula libekwa ebhentshini lokusebenza elimise okuka-V, bese i-HRS-150S yedijithali yokuhlola ubulukhuni be-Rockwell isetshenziselwa ukuhlola ngokuqondile ubulukhuni be-Rockwell endaweni yayo engaphandle enomthwalo ongu-980.7N. Ngemva kokuhlolwa, kungase kubonakale ukuthi udonga lwamapayipi ensimbi lunokuwohloka okuncane, futhi umphumela uba ukuthi inani lobulukhuni be-Rockwell elilinganiselwe liphansi kakhulu, okuholela ekuhlolweni okungavumelekile.
Ngokuya nge-GB/T 230.1-2018 «Metallic Materials Rockwell Hardness Test Part 1: Test Method», ubulukhuni be-Rockwell bungu-80HRBW kanti ubuncane besampula ukujiya bungu-1.5mm. Ugqinsi lwesampula No. 1 ngu-1.65mm, ukujiya kongqimba olukhishwe yi-decarburized kungu-0.15~0.20mm, futhi ukujiya kwesampula ngemva kokukhipha isendlalelo se-decarburized kungu-1.4~1.45mm, okuseduze nobukhulu obuncane besampula obucaciswe ku-GB/T 230.1-2018. Ngesikhathi sokuhlolwa, njengoba kungekho ukusekelwa phakathi nendawo yesampula, kuzodala ukuwohloka okuncane (okungase kungabonakali ngeso lenyama), ngakho-ke inani langempela lobulukhuni be-Rockwell liphansi.
2) Indlela yokukhetha umhloli wokuqina wokuqina wamapayipi ensimbi:
Ngemva kokuhlolwa okuningi ngobulukhuni bobuso bamapayipi ensimbi, inkampani yethu isifinyelele eziphethweni ezilandelayo:
1. Lapho kuhlolwa ubulukhuni be-Rockwell obungaphezulu noma ukuhlolwa kokuqina kwe-Rockwell ebusweni bamapayipi ensimbi anezindonga ezincane, ukusekela okunganele kodonga lwamapayipi kuzodala ukuguquguquka kwesifanekiso futhi kuholele emiphumeleni yokuhlola ephansi;
2. Uma ukwesekwa kwe-cylindrical kwengezwa phakathi kwepayipi yensimbi enezindonga ezincane, imiphumela yokuhlola izoba phansi ngoba i-axis yekhanda lokucindezela kanye nesiqondiso sokulayisha umthwalo asikwazi ukuqinisekiswa ukuthi i-perpendicular ebusweni bombhobho wensimbi, futhi kukhona igebe phakathi kwendawo yangaphandle yepayipi yensimbi kanye nokusekelwa kwe-cylindrical okufakiwe.
3. Indlela yokuguqula ubulukhuni be-Vickers obulinganisiwe bube ubulukhuni be-Rockwell ngemva kokunamathisela nokupholisha isampula yepayipi lensimbi inembe uma kuqhathaniswa.
4. Ngemva kokukhipha isikali se-oxide kanye nesendlalelo se-decarburization ebusweni bepayipi lensimbi nokucubungula indiza yokuhlola endaweni engaphandle futhi ifakwe ngaphakathi, ubulukhuni be-Rockwell obungaphezulu buguqulwa bube bulukhuni be-Rockwell, obunembile ngokuqhathaniswa.
