Momwe mungayang'anire ngati hardness tester ikugwira ntchito bwino?
1.The hardness tester iyenera kutsimikiziridwa mokwanira kamodzi pamwezi.
2. Malo oyikapo oyesa kuuma ayenera kusungidwa pamalo owuma, osagwedezeka komanso osawononga, kuti atsimikizire kuti chipangizocho chili cholondola panthawi yoyezera komanso kukhazikika ndi kudalirika kwa mtengo panthawi yoyesera.
3. Pamene woyesa kuuma akugwira ntchito, sikuloledwa kukhudza mwachindunji pamwamba pa chitsulo kuti ayesedwe kuti ateteze kulondola kwa kuyeza molakwika kapena kuwononga diamondi cone indenter pamutu wa tester hardness.
4. Pogwiritsa ntchito diamondi ya diamondi, m'pofunika kuyang'ana pamwamba pa mapeto a indenter kamodzi pachaka.Pambuyo pa muyeso uliwonse, indenter iyenera kubwezeretsedwa m'bokosi lapadera kuti isungidwe.

Chitetezo cha Hardness tester:
Kuphatikiza pa kusamala kwapadera mukamagwiritsa ntchito zoyesa zolimba zosiyanasiyana, pali zovuta zina zomwe ziyenera kutsatiridwa, zomwe zalembedwa pansipa:
1. Woyesa kuuma yekha adzatulutsa mitundu iwiri ya zolakwika: chimodzi ndi cholakwika chomwe chimadza chifukwa cha kupunduka ndi kuyenda kwa ziwalo zake;chinacho ndi cholakwika chomwe chimabwera chifukwa cha kuuma kopitilira muyeso womwe watchulidwa.Pakulakwitsa kwachiwiri, choyesa cholimba chimayenera kuyesedwa ndi chipika chokhazikika chisanayezedwe.Pazotsatira zoyeserera za Rockwell hardness tester, kusiyana kumakwanira mkati mwa ± 1.Mtengo wowongolera ukhoza kuperekedwa kwa mtengo wokhazikika ndi kusiyana pakati pa ± 2.Kusiyanako kukakhala kunja kwa ± 2, ndikofunikira kuyeza ndikukonza choyesa kuuma kapena kusintha njira zina zoyezera kuuma.
Mulingo uliwonse wa kuuma kwa Rockwell uli ndi kuchuluka kwa ntchito, komwe kuyenera kusankhidwa moyenera malinga ndi malamulo.Mwachitsanzo, kuuma kukakhala kwakukulu kuposa HRB100, sikelo ya HRC iyenera kugwiritsidwa ntchito poyesa;kuuma kukakhala kotsika kuposa HRC20, sikelo ya HRB iyenera kugwiritsidwa ntchito poyesa.Chifukwa kulondola ndi kukhudzika kwa tester hardness ndizosauka pamene mayeso adutsa, ndipo mtengo wa kuuma ndi wolakwika, siwoyenera kugwiritsidwa ntchito.Njira zina zoyezera kuuma zilinso ndi milingo yofananira.Chipilala chokhazikika chomwe chimagwiritsidwa ntchito poyesa kuyesa kuuma sichingagwiritsidwe ntchito mbali zonse ziwiri, chifukwa kuuma kwa mbali yokhazikika ndi kumbuyo sikufanana.Nthawi zambiri zimanenedwa kuti chipika chokhazikika chimakhala chovomerezeka mkati mwa chaka chimodzi kuyambira tsiku loyeserera.
2. Mukasintha cholozera kapena chivundikiro, tcherani khutu kuyeretsa magawo olumikizana.Pambuyo posintha, yesani kangapo ndi chitsanzo chachitsulo cha kuuma kwina mpaka mtengo wouma womwe umapezeka kawiri mzere uli wofanana.Cholinga chake ndi kupanga indenter kapena anvil ndi gawo lolumikizana la makina oyesera mwamphamvu ndikulumikizana bwino, kuti zisakhudze kulondola kwa zotsatira za mayeso.
3. Pambuyo poyesa kuuma kusinthidwa, poyambira kuyeza kuuma, kuyesa koyamba sikugwiritsidwa ntchito.Poopa kukhudzana koyipa pakati pa chitsanzo ndi anvil, mtengo woyezedwa ndi wolakwika.Mfundo yoyamba itatha kuyesedwa ndipo woyesa kuuma ali mumkhalidwe wokhazikika wogwirira ntchito, chitsanzocho chimayesedwa mwachisawawa ndipo mtengo woyezera kuuma umalembedwa.
4. Ngati chidutswa choyesera chikuloleza, nthawi zambiri sankhani magawo osiyanasiyana kuti muyese osachepera atatu olimba, mutenge mtengo wapakati, ndipo mutenge mtengo wamtengo wapatali monga mtengo wa kuuma kwa chidutswa choyesera.
5. Pazigawo zoyesera zokhala ndi mawonekedwe ovuta, mapepala a mawonekedwe ofanana ayenera kugwiritsidwa ntchito, ndipo akhoza kuyesedwa atakhazikika.Chidutswa choyesera chozungulira nthawi zambiri chimayikidwa mumphuno yooneka ngati V kuti iyesedwe.
6. Musanayambe kutsitsa, fufuzani ngati chogwiriziracho chikuyikidwa pamalo otsitsa.Pokweza, chochitacho chiyenera kukhala chopepuka komanso chokhazikika, ndipo musagwiritse ntchito mphamvu zambiri.Pambuyo ponyamula, chogwirizira chonyamula chiyenera kuyikidwa pamalo otsitsa, kuti ateteze chidacho kuti chisamalemedwe kwa nthawi yayitali, kupangitsa kusinthika kwa pulasitiki ndikukhudza kulondola kwa kuyeza.
Vickers, Rockwell kuuma
Kuuma: Ndi kuthekera kwa chinthu kukana kupunduka kwa pulasitiki kwanuko, ndipo kumayesedwa kwambiri ndi njira yolowera.
Zindikirani: Makhalidwe owuma sangafanane mwachindunji ndi wina ndi mzake, ndipo akhoza kutembenuzidwa kupyolera mu tebulo loyerekeza la kuuma.

Mu 2019, Shandong Shancai Testing Instrument Co., Ltd. adalowa nawo National Testing Machine Standardization Technical Committee ndipo adatenga nawo gawo pakupanga mfundo ziwiri zamayiko.
1. GB/T 230.2-2022: "Mayeso a Metallic Rockwell Hardness Gawo 2: Kuyang'ana ndi Kuwongolera kwa Mayeso Olimba ndi Ma Ininters"
2. GB/T 231.2-2022:"Mayeso a Zitsulo a Brinell Hardness Gawo 2: Kuyang'ana ndi Kuyesa Mayeso a Kuuma"

Mu 2021, Shandong Shancai adagwira nawo ntchito yomanga pulojekiti yoyezetsa kuuma kwapaintaneti ya mapaipi a injini yazamlengalenga, zomwe zimathandizira pamakampani azamlengalenga a dziko la mama.
