Ine.Kukonzekera Mayeso
1. Kukhuthala kwa chitsanzo chokonzedwa sikuyenera kuchepera nthawi 8 kuposa kuya kwa kulowetsa (nthawi zambiri ≥10mm) kuti kulowetsako kusalowe mu chitsanzo kapena kukhudzidwa ndi chithandizo cha pansi.
2. Valani magolovesi oteteza pamene mukugwiritsira ntchito kuti mupewe kukhudzana mwachindunji pakati pa zala ndi pamwamba pa chitsanzo, zomwe zingayambitse kuipitsidwa kapena kukwawa.
3. Ngati zitsanzo zosiyanasiyana ziyenera kusiyanitsa, lembani manambala otsatizana pamalo osayesa kuti mupewe kusokoneza malo olowera.
4. Onetsetsani kuti chitsanzocho chikugwirizana ndi chipangizo choyezera (monga tungsten carbide indenter imafunika pa zipangizo zolimba kwambiri) kuti mupewe kuwonongeka kwambiri kwa chipangizocho kapena kusweka kwa chitsanzocho.
II. Njira Zogwirira Ntchito
1. Kuyambitsa Zida ndi Kudziyesa
Mukatsimikizira kuti chingwe chamagetsi cha chipangizocho chalumikizidwa bwino, chiyikeni mu soketi yamagetsi ya 220V, 50/60Hz ndikuyatsa switch yakumbuyo. Chipangizocho chidzadziyesa chokha, chinsalu chowonetsera chidzayatsa ndikuwonetsa mawonekedwe oyamba. Pambuyo poti kudziyesa kwatha, chipangizocho chidzayambiranso chokha ndikulowa mu mkhalidwe woyimirira kuti chigwire ntchito.
.
2. Kukhazikitsa ndi Kukhazikitsa Indenter
Kutengera ndi makhalidwe a zinthu zomwe zikuyezedwa, sankhani choyimira mpira wa carbide cholimba cha kukula koyenera (φ2.5, 5, 10 mm). Tsukani mafuta oletsa dzimbiri ndi mowa ndikupukuta mpaka kumapeto kosalala ndi nsalu yoyera ya thonje. Ikani choyimira mu dzenje la spindle ndikuzungulira screw yokonzera kuti igwirizane ndi gawo lathyathyathya la shank ya indenter, ndikutsimikizira kuyika kolimba. Kenako sankhani nsanja yoyesera (pulatifomu yayikulu yathyathyathya, nsanja yaying'ono yathyathyathya, nsanja yooneka ngati V) malinga ndi mawonekedwe a chitsanzo, ikani chitsanzocho mokhazikika komanso mwamphamvu, ndikuwonetsetsa kuti pamwamba pake pali oyera komanso opanda zodetsa.
3. Kusankha ndi Kukhazikitsa Mphamvu Yoyesera
Choyesera cha HB-3000C Electronic Brinell Hardness Tester chimapereka mphamvu zoyesera zolondola za milingo 10 (kuyambira 612.9 N mpaka 29421 N). Wogwiritsa ntchitoyo amatha kusankha mphamvu yofunikira pazenera logwira la mainchesi 8 malinga ndi zofunikira pakuyesa, ndipo choyeseracho chidzakonza zokha zolemera kuti chikwaniritse mphamvu yoyesera yomwe yakhazikitsidwa.
Pakadali pano, nthawi yogwiritsira ntchito chipangizocho imatha kukhazikitsidwa kuyambira masekondi 0 mpaka 60 pa sikirini yokhudza kutengera mawonekedwe a chipangizocho. Pazinthu zonse, nthawi yogwiritsira ntchito chipangizocho ndi masekondi 10-15.
4. Mayeso a Brinell Kuuma
Ikani chogwirira ntchito pa benchi yogwirira ntchito, ndipo zungulirani gudumu lamanja mozungulira wotchi pa liwiro lokhazikika komanso lofanana kuti mukweze gawo la chitsanzo. Siyani kuzungulira nthawi yomweyo beep ikamveka pamene chitsanzo chikhudza indenter.
Woyesayo adzayambitsa mayesowo, omwe akuphatikizapo kugwiritsa ntchito, kugwira, ndikutsitsa mphamvu yayikulu yoyesera motsatizana kuti apange kabowo. Kenako tembenuzani gudumu lamanja motsutsa wotchi kuti muchepetse gawo la chitsanzo ndikuchotsa chitsanzo choyesedwacho.
5. Muyeso wa Brinell Kuuma kwa Indentation
Chotsani chitsanzo, chomwe chidzawoneka ngati chozungulira. Yesani kukula kwa chozungulira pogwiritsa ntchito maikulosikopu yoyezera ya 20×, kenako lowetsani mtengo woyezedwa mu gulu la hB-3000C Brinell Hardness Tester. Dongosololi lidzawerengera lokha kuchuluka kwa kuuma kutengera fomula yokonzedweratu.
Kapenanso, pali njira yoyesera ya Brinell yomwe mungasankhe. Njirayi imagwira chithunzi cha indentation kudzera mu sensa ya CCD, ndipo mtengo wa kuuma umayesedwa ndikuwonetsedwa ndi kompyuta yokha.
6. Kulemba Deta ndi Kupanga Malipoti
Pambuyo poyesa, wogwiritsa ntchito amatha kuwona zambiri pa sikirini yokhudza, kuphatikiza kuchuluka kwa kuuma, mainchesi a indentation, ndi zambiri za ziwerengero (mtengo wapamwamba, mtengo wocheperako, mtengo wapakati, ndi zina zotero). Zambiri zitha kusungidwa mu kukumbukira kwamkati kwa woyesa kapena ku chipangizo chosungira chakunja cha USB.
Kuphatikiza apo, pulogalamu yoyesera imatha kupanga lipoti la Word lokhala ndi deta yoyezera, zotsatira za ziwerengero ndi zithunzi, zomwe zitha kusindikizidwa kapena kutumizidwa kunja ndi wogwiritsa ntchito.
III.Kusamalira ndi Kusamala
1. Pambuyo poyesa, tulutsani mphamvu zonse zoyesera, sankhani njira yozimitsa pa sikirini yokhudza, ndikuzimitsa switch yamagetsi ya chipangizocho.
2. Ngati zipangizo sizikugwiritsidwa ntchito kwa nthawi yayitali, dulani chingwe chamagetsi, chotsani zinthu monga indenter ndi zolemera, zitsukeni bwino, ndikuzisunga bwino pamalo osankhidwa kuti mupewe kuwonongeka kapena kutayika.
3. Yeretsani ndi kukonza zida nthawi zonse. Yang'anani momwe zida zogwirira ntchito zimakhalira kuphatikizapo cholumikizira ndi zolemera, ndipo sinthani zida zilizonse zowonongeka kapena zosweka kwambiri nthawi yake. Sungani malo ogwirira ntchito a zidazo oyera komanso ouma kuti mupewe kuwonongeka komwe kumachitika chifukwa cha fumbi, chinyezi, kapena zinthu zina zodetsa.
4. Valani zida zodzitetezera zofunika (monga magalasi oteteza ndi magolovesi oteteza) mukamachita opaleshoni kuti mupewe kuvulala chifukwa cha ngozi.
5. Gwiritsani ntchito zidazo motsatira malangizo ogwiritsira ntchito. Musasinthe mwachisawawa makonda a zidazo kapena njira zogwiritsira ntchito, kuti muwonetsetse kuti zotsatira za mayeso ndi zolondola komanso zodalirika.
6. Ngati zipangizo sizikugwira ntchito bwino kapena zinthu sizikuyenda bwino, siyani kugwira ntchito nthawi yomweyo ndikudula magetsi, kenako funsani akatswiri okonza kuti akayang'ane ndi kukonza.
