Zosamba ndi zinthu zosambira zomwe tiyenera kugwiritsa ntchito tsiku lililonse pamoyo wathu watsiku ndi tsiku.Mashawa amatha kugawidwa m'mitundu iwiri: mashawa ogwirizira pamanja ndi mashawa osakhazikika.Momwe mungayang'anire mutu wakusamba?Ndi chiyanimiyezo yoyenderaza shawa?Mawonekedwe ndi chiyanikuyendera miyezozopangira shawa?
Kuyang'anira mawonekedwe azinthu
Kuyang'anira zowoneka pa mtunda wa 600 mm ± 50 mm kuchokera kumutu wakusamba pansi pa kuyatsa kwa 3001x20 1x
1.Kunja kwa kunja kwazitsulo zamkuwa kuyenera kukhala ndi zolakwika monga shrinkage cavities, matuza, ming'alu ndi pores, ndipo mkati mwake sayenera kukhala ndi mchenga wowuma kumamatira;
2.Kunja kwa mbali za pulasitiki siziyenera kukhala ndi zolakwika zoonekeratu monga ma ripples, scratches, zowonongeka zowonongeka, etc.;
3.Mawonekedwe onse omwe angakhudzidwe ndi thupi la munthu pakugwiritsa ntchito sayenera kukhala ndi ngodya zakuthwa kapena zoopsa zina zobisika zomwe zingayambitse thupi la munthu.
4.Pambuyo pa kukhazikitsa, sikuyenera kukhala madera osatsekedwa pamtunda wa electroplated.Pamwamba payenera kukhala yowala komanso yofanana, ndipo palibe kusenda, kusenda, matuza, ndi zina zambiri.
Kuyesa kwakuthupi ndi kwamankhwala
1. Kuwunika kulondola kwa ulusi wa chitoliro
Kulondola kwa ulusi wa chitoliro cha kugwirizana kwakunja kwa mutu wa shawa kuyenera kuyesedwa ndi ulusi wa ulusi wolondola.Kulondola kwa ulusi wa chitoliro kwa kulumikizana kwakunja kwa mutu wa shawa kuyenera kukwaniritsa zofunikira zolondola.
2.Kuwunika kachitidwe kachitetezo
- Ikani mutu wa shawa womwe ukugwiritsidwa ntchito.Pambuyo pa kutentha kwa madzi ndi 42 C2C, kuthamanga kwamphamvu ndi 0.10 MPa0.02 MPa ndi mphamvu yamphamvu ndi 0.30 MPa ± 0.02 MPa.Mukatha kugwiritsa ntchito mokhazikika kwa mphindi 10 ndi masekondi 10, fufuzani ngati mbali zonse za mutu wa shawa zili bwino pamanja.Zosinthika, fufuzani mutu wa shawa, chigawo chilichonse cha mutu wa kusamba chiyenera kukhala chosinthika, mutu wa kusamba suyenera kukhala ndi maonekedwe oonekera, ndipo mawonekedwe ake a ndege amadzi sayenera kusintha.
- Ikani mutu wa shawa womwe ukugwiritsidwa ntchito, ndi kutentha kwa madzi pa 70 C ± 2 C, kuthamanga kwamphamvu 0.05 MPa 0.02 MPa ndi kuthamanga kwamphamvu 0.50 MPa ± 0.02 MPa motsatana.Mukatha kugwiritsa ntchito mokhazikika kwa mphindi 10 ndi 10 s, yang'anani mbali zosiyanasiyana za mutu wa shawa ndi dzanja.Yang'anani ngati zigawozo ndi zosinthika.Yang'anani mutu wa shawa.Gawo lililonse la mutu wa shawa liyenera kukhala losinthasintha, mutu wa shawa uyenera kukhala wopanda mawonekedwe owoneka bwino, ndipo mawonekedwe ake a jet amadzi sayenera kusintha.
3.Kupaka pamwamba ndi plating khalidwe
- Kuzizira kofulumira komanso kuyesa kwachangu kwa kutentha kwachangu
Njira zoyezera zofunikira pakuyala pamwamba ndi kuyika zigawo zapulasitiki ndi izi:
a) Ikani chitsanzo mu uvuni ndi kutentha kwa 70 ° C ± 2C ndikusunga kwa mphindi 30;
b) Nthawi yomweyo ikani chitsanzo pa kutentha kwa 15C ~ 20C kwa mphindi 15;
c) Nthawi yomweyo ikani chitsanzo pa kutentha kwa -30C~-25C kwa mphindi 30;
d) Nthawi yomweyo ikani chitsanzo pa kutentha kwa 15C ~ 20C kwa mphindi 15.
Zomwe zili pamwambazi ndi kuzizira kofulumira komanso kutentha kwachangu kuyesa kuzungulira, ndipo mayesowo amachitidwa moyenerera, kwa mizere 5 yonse.Pambuyo mayeso mkombero, zowoneka kuyendera ngati ❖ kuyanika pamwamba chitsanzo kuonongeka pansi pa kuwala gwero anamwazikana 700 1x ~ 1 000 x mwamphamvu pa mtunda wa 300 mm ndi 20 mm kuchokera chitsanzo.
4.Kusindikiza magwiridwe antchito
Lumikizani chitsanzo ku payipi yoperekera madzi.Kutentha kwa madzi ndi 70°C ± 2°C.Kupanikizika kwamphamvu kwa mayeso ndi 0.05 MPa ± 0.02 MPa ndi 0.50 MPa ± 0.02 MPa kwa mphindi 5 ± 10 s motsatana.Onani ngati pali kutayikira kulikonse pakati pa mutu wa shawa ndi zigawo zake zolumikizira.Kutuluka kwa madzi.
5.Kuwunika mphamvu zamakina
Pasakhale ming'alu, mawonekedwe owoneka okhazikika kapena kuwonongeka kwina pambuyo poyang'anira.
6.Hot ndi kuzizira kutopa kukana ntchito mayeso
Kutentha kwa madzi kumapeto kwa madzi otentha ndi 70 C2, kutentha kwa madzi kumapeto kwa madzi ozizira ndi 20 C2, ndipo madzi othamanga ndi 0.30 MPa ± 0.02 MPa.Pochita mayeso pazipita otaya zida ndi kutembenuka nthawi si upambana 2 s, 2 n madzi ozizira amaperekedwa poyamba, ndiyeno 2 min madzi otentha, kwa mkombero umodzi, kuchita 300 mkombero mayesero.Pambuyo poyang'anitsitsa, sikuyenera kukhala kutayikira, ming'alu, zowoneka zokhazikika komanso zolephera zogwira ntchito.
7.Kuyendera kwakuyenda
Kutentha kwa madzi oyesera T<30C, mayeso ali ndi njira zotsatirazi
- Sinthani chipangizo choyesera pamagetsi amphamvu a 0.10 MPa ± 0.02 MPa, sungani kupanikizika kwa mphindi imodzi, kenako lembani kuthamanga kwa q1.Sungani mawonekedwe a chipangizo choyesera osasinthika ndikuzimitsa madzi.
- Ikani chitsanzo pa chipangizo choyesera, yambitsani madzi, sinthani kuyesa kwamphamvu kwa 0.10 MPa ± 0.02 MPa, sungani kupanikizika kwa mphindi imodzi, yesani ndi kulemba kuthamanga kwa mutu wa kusamba;yesani katatu, ndikutenga masamu amatanthauza Q1.
| kalembedwe | liwiro loyenda |
| shawa lamanja | ≤7.5 |
| Mutu wosambira wokhazikika | ≤9.0 |
8.Kuwunika magwiridwe antchito
Ikani ndi kukonza polowera madzi osambira ndi ulusi wolumikizira wofananira, ikani mphamvu yokoka axial F ya 500 N10 N pamutu wa shawa, ndikuyisunga kwa 15 s5.Yang'anani ngati pali kuwonongeka kodziwikiratu kwa chogwirira cha shawa, mutu wa shawa, ndi zina zambiri pagawo lililonse lolumikizana.Chotsani mutu wa shawa ndikulumikiza ku payipi yoperekera madzi.Sungani kwa mphindi 5 ± 5 s pansi pa kutentha kwa madzi osapitirira 30C ndi kuthamanga kwamphamvu kwa .50 MPa0.02 MP.Yang'anani ngati pali kutayikira mu mutu wa shawa ndi magawo ake olumikizira..
9.Resistance ku unsembe katundu anayendera
The shawa kugwirizana chitoliro ulusi kukana unsembe unsembe adzayesedwa malinga ndi malamulo.Pambuyo pa mayesero, ulusi sudzakhala ndi ming'alu, palibe kuwonongeka ndikukwaniritsa zofunikira pa tebulo ili m'munsimu.
| kalembedwe | Mtundu wa ulusi wolumikizira | mphindi ya torsional |
| shawa lamanja | Pulasitiki/Chitsulo cholumikizira | ≥5 |
| Mutu wosambira wokhazikika | Cholumikizira pulasitiki | ≥5 |
| cholumikizira zitsulo | ≥20 |
10.Kuzizira mayeso
Zimanenedwa kuti kutentha sikuyenera kupitirira 3C panthawi ya mayesero.
11.Shower ntchito kutembenuka moyo mayeso
Mayesowa ayenera kuchitidwa posamba ndi ma jets amadzi 2 kapena kupitilira apo.Pambuyo pa maulendo a 10,000 monga momwe tafotokozera, zofunikira ziyenera kukwaniritsidwa.
12.Kusamba kwamanja kwa anti-siphon
M'madzi osambira, ngati zigawo zogwirizanitsa kupatulapo mutu wosambira m'manja, monga ma hoses ndi ma faucets, mulibe zida zotsutsana ndi siphon, mutu wosamba m'manja uyenera kukhala ndi anti-siphon ntchito.Ntchito yotsutsana ndi siphonage imayesedwa motsatira malamulo, ndipo palibe madzi owoneka mu chitoliro chotseguka.
13.Swing performance test of spherical connection
Kwa ma shawa osasunthika osunthika kapena mitu ya shawa yokhala ndi zolumikizira mpira, mayesowa ayenera kuchitidwa.Pambuyo pa maulendo a 10,000 motsatira malamulo, mbali zogwirizanitsa mpira siziyenera kutayikira ndipo ziyenera kukwaniritsa zofunikira.
14.Function kusintha mphamvu kuyesa
Pamutu wosambira wogwiritsa ntchito zambiri, gwirizanitsani chitsanzo ndi payipi yoperekera madzi pansi pa kutentha kwa madzi T≤30 ° ndi kuthamanga kwamphamvu 0.25 MP ± 0.02 MPa, ndikugwiritsa ntchito kuyesa kwa mita kuti musinthe mtengo wamagetsi pa mapeto a chogwirira.Ntchito yake yosinthira mphamvu kapena torque siyenera kukhala yayikulu kuposa 45 kapena 1.7 N · m;kwa zinthu zopangidwira olumala, asanayesedwe komanso pambuyo pake, siziyenera kupitilira 22N.
15.Kuyesa kwamphamvu kwa mpira kumutu
Kwa mashawa osunthika osunthika okhala ndi maulumikizidwe a mpira, mphamvu yakugwedezeka kwa mutu imayenera kuyesedwa ndipo isapitirire 45N.
16.Drop mayeso
Mitu yosamba m'manja imayesedwa motsatira malamulo, ndipo palibe kupunduka kapena ming'alu yomwe imakhudza chitetezo ndi ntchito yabwinobwino imaloledwa.Zigawo zomwe zimasiyanitsidwa kapena kugwa panthawi ya mayeso zitha kubwezeretsedwanso ndipo chitsanzocho chiyenera kugwira ntchito bwino.Pambuyo pa kuyesedwa, kusamba m'manja kumayenera kutsatira zofunikira.
17.Kuyendera mphamvu ya jekeseni
Akayesedwa molingana ndi malamulo, mphamvu yopopera ya shawa ya m'manja siyenera kukhala yochepera 0.85 N. Ngati vinyo wamaluwa omwe ali mmenemo ali ndi njira zambiri zotulutsira madzi, mphamvu yopopera yowonjezera idzagwiritsidwa ntchito.
