Tensile mphamvu tester pansi pa chikhalidwe kuthamanga mosalekeza kutsitsa, chitsanzo cha kukula kwapadera kumatambasulidwa mpaka kuthyoka, kulimba kwa mphamvu kumayesedwa, ndipo kutalika kwakukulu kwa fracture kumalembedwa.
Ⅰ Tanthauzirani
Matanthauzidwe otsatirawa amatsatiridwa ndi Mulingo wapadziko lonse uwu.
1, Mphamvu yamagetsi
Kupanikizika kwakukulu komwe mapepala kapena makatoni angathe kupirira.
2. Kuphwanya kutalika
M'lifupi la pepala lokha lidzakhala logwirizana ndi khalidwe la pepala lidzasweka pamene kutalika kumafunika. Imawerengedwa mochulukira kuchokera ku mphamvu yamphamvu ndi chinyezi chosalekeza cha chitsanzo.
3.Tambasulani panthawi yopuma
The elongation wa pepala kapena bolodi pansi chipwirikiti kuthyoka, anasonyeza monga kuchuluka kwa kutalika kwa chitsanzo choyambirira.
4, Kukhazikika kwa index
Mphamvu yokhazikika imagawidwa ndi kuchuluka komwe kumawonetsedwa mu Newtons metres pa gramu.
Ⅱ Chida
Choyesa mphamvu champhamvu chiyenera kugwiritsidwa ntchito poyesa kulimba kwamphamvu ndi kutalika kwa chitsanzocho pamlingo wokhazikika womwe umayikidwa. Tensile mphamvu tester ikuphatikizapo:
1. Kuyeza ndi kujambula chipangizo
Kulondola kwa kukana kwamphamvu pakusweka kuyenera kukhala 1%, ndipo kulondola kwa kuwerenga kwa elongation kuyenera kukhala 0.5mm. Muyezo woyezera woyezetsa mphamvu wamagetsi uyenera kukhala pakati pa 20% ndi 90% yamitundu yonse. Zindikirani: kwa pepala lokhala ndi elongation yochepera 2%, ngati sizolondola kugwiritsa ntchito pendulum tester kuti mudziwe kutalika, kuyesa kothamanga kosalekeza ndi amplifier zamagetsi ndi chojambulira ziyenera kugwiritsidwa ntchito.
2. Kusintha kwa liwiro lotsitsa
Zindikirani: Kuti mukwaniritse zofunikira kuti kusintha kwa kukweza kusakhale kwakukulu kuposa 5%, chida chamtundu wa pendulum sichiyenera kugwiritsidwa ntchito pa pendulum Angle yaikulu kuposa 50 °.
3. Zitsanzo ziwiri tatifupi
Zitsanzo ziyenera kumangika pamodzi m'lifupi mwake ndipo zisagwedezeke kapena kuziwononga. Mzere wapakati wa clamp uyenera kukhala coaxial ndi mzere wapakati wa chitsanzo, ndipo mayendedwe a clamping mphamvu ayenera kukhala 1 ° ofukula mpaka kutalika kwa chitsanzo. Pamwamba kapena mzere wa zigawo ziwirizo ziyenera kukhala 1 ° zofanana.
4, magawo awiri a clip
Mtunda wapakati pazigawo ziwirizi ndi wosinthika ndipo uyenera kusinthidwa kuti ukhale wofunikira kutalika kwa mayeso, koma cholakwikacho chisapitirire 1.0 mm.
Ⅲ Kutenga ndi kukonzekera zitsanzo
1, Chitsanzocho chiyenera kutengedwa molingana ndi GB/T 450.
2, 15 mm kutali ndi m'mphepete mwa chitsanzo, dulani chiwerengero chokwanira cha zitsanzo, kuti muwonetsetse kuti pali 10 deta yolondola mu njira yowongoka ndi yopingasa. Chitsanzocho chiyenera kukhala chopanda mapepala omwe amakhudza mphamvu.
Mbali ziwiri za chitsanzo ndizowongoka, kufanana kuyenera kukhala mkati mwa 0.1mm, ndipo kudulidwa kuyenera kukhala kopanda kuwonongeka. Zindikirani: podula mapepala ofewa ofewa, chitsanzocho chikhoza kutengedwa ndi pepala lolimba.
3, kukula kwachitsanzo
(1) M'lifupi mwa chitsanzocho chiyenera kukhala (15 + 0) mm, ngati m'lifupi mwake kuyenera kuwonetsedwa mu lipoti la mayeso;
(2) Chitsanzocho chiyenera kukhala chokwanira kutalika kuti zitsimikizire kuti chitsanzo sichidzakhudza chitsanzo pakati pa zojambulajambula. Kawirikawiri kutalika kwachidule kwa chitsanzo ndi 250 mm; Masamba olembedwa pamanja a labotale adzadulidwa motsatira miyezo yawo. Kutalika kwa clamping panthawi ya mayeso kuyenera kukhala 180 mm. Ngati mtunda wina wokhomerera ugwiritsidwa ntchito, uyenera kuwonetsedwa mu lipoti la mayeso.
ⅣYesani njira
1. Kusintha kwa zida ndikusintha
Ikani chidacho molingana ndi malangizo ndikuyesa njira yoyezera mphamvu molingana ndi Zowonjezera A. Ngati ndi kotheka, njira yoyezera elongation iyeneranso kuyesedwa. Sinthani liwiro lotsitsa malinga ndi 5.2.
Sinthani katundu wa ma clamps kuti mzere woyeserera usagwedezeke kapena kuonongeka panthawi ya mayeso.
Kulemera koyenera kumakanikizidwa ku kopanira ndipo kulemera kwake kumayendetsa chipangizo cholozera kuti chilembe kuwerenga kwake. Poyang'ana njira yowonetsera, njira yowonetsera sikuyenera kukhala ndi backbump, lag kapena mikangano yambiri. Ngati cholakwikacho ndi chachikulu kuposa 1%, njira yowongolera iyenera kupangidwa.
2, Kuyeza
Zitsanzo anayesedwa pansi muyezo mumlengalenga zinthu kutentha ndi chinyezi mankhwala. Yang'anani zero ndi kutsogolo ndi kumbuyo kwa makina oyezera ndi chipangizo chojambulira. Sinthani mtunda pakati pa zingwe za kumtunda ndi zapansi, ndipo chepetsani chitsanzocho muzitsulozo kuti mupewe kukhudza m'manja ndi malo oyesera pakati pa zingwe. Kuthamanga kwapafupifupi pafupifupi 98 mN(10g) kumagwiritsidwa ntchito pazatsanzo kotero kuti imakanizidwa molunjika pakati pazigawo ziwirizo. Kuchuluka kwa kusweka kwa fracture mu (20 dothi 5) s kunawerengedwera ndi mayeso olosera. Mphamvu yayikulu yogwiritsidwa ntchito iyenera kulembedwa kuyambira pachiyambi cha kuyeza mpaka chitsanzocho chisweka. Elongation panthawi yopuma iyenera kulembedwa ngati kuli kofunikira. Pafupi mapepala 10 a mapepala ndi bolodi ayesedwe mbali iliyonse ndipo zotsatira za mizere khumi ziyenera kukhala zovomerezeka. Ngati cholumikizira chathyoledwa mkati mwa 10 mm, chiyenera kutayidwa.
ⅤZotsatira zawerengedwa
Zotsatirazo zinasonyeza kuti zotsatira zowongoka ndi zopingasa za mapepala ndi makatoni zinawerengedwa ndikuyimiridwa motsatira, ndipo panalibe kusiyana pakati pa ma laboratory omwe amakopera pamanja masamba.
Malinga ndi muyezo wa "GB/T 453-2002 IDT ISO 1924-1: 1992 kutsimikiza kwamphamvu kwa pepala ndi bolodi (njira yotsitsa liwiro nthawi zonse)" kampani yathu idapanga zida za DRK101 mndandanda wamakina oyesera amagetsi. Lili ndi izi:
1, Njira yotumizira imatengera wononga mpira, kufalitsa kumakhala kokhazikika komanso kolondola; Magalimoto a servo ochokera kunja, phokoso lochepa, kuwongolera kolondola.
2, Chiwonetsero cha mawonekedwe a Touch screen, Chinese and English exchange menu. Chiwonetsero cha nthawi yeniyeni ya nthawi ya mphamvu, mphamvu-kusintha, kusuntha kwa mphamvu, ndi zina zotero. Chidacho chili ndi mphamvu zowonetsera deta, kusanthula ndi kuwongolera.
3, Kugwiritsa ntchito 24-bit high precision AD converter (kusamvana mpaka 1/10,000,000) ndi sensor yolondola kwambiri yoyezera, kuwonetsetsa kuthamanga ndi kulondola kwa chida chokakamiza kupeza deta.
4, Kugwiritsa ntchito modular chosindikizira matenthedwe, kukhazikitsa kosavuta, cholakwika chochepa.
5,Zotsatira za kuyeza kwachindunji: mukamaliza mayeso a gulu, ndikosavuta kuwonetsa zotsatira zoyezera ndikusindikiza malipoti a ziwerengero, kuphatikiza kutanthawuza, kupatuka kokhazikika komanso kusiyanasiyana kwamitundu.
6, High degree of automation, kapangidwe ka zida zimagwiritsa ntchito zida zapamwamba kunyumba ndi kunja, ma microcomputer kuti azitha kudziwa zambiri, kukonza deta ndi kuwongolera zochita, ndikukhazikitsanso zokha, kukumbukira kwa data, kutetezedwa mochulukira komanso kudzizindikiritsa nokha.
7, Multi-function, kusintha kosinthika.
