Mukapanga kufa pang'onopang'ono, kukakamiza kopanda kanthu, kupanikizika, ndi zida zonse zimakhudza kuthekera kopeza zotsatira zosasinthika popanda makwinya.
Q: Tikujambula makapu kuchokera ku kalasi ya 304 zitsulo zosapanga dzimbiri. Pamayimidwe oyambirira a kufa kwathu kopita patsogolo, timakoka pafupifupi masentimita 0,75. Ndikayang'ana makulidwe a flange perimeter ya chopanda kanthu, kusiyana kwa mbali ndi mbali kungakhale pamwamba mpaka 0.003 mainchesi. m'mphepete mwa koyilo yayikulu.Kodi tingapeze bwanji kapu yowoneka bwino popanda makwinya?
A: Ndikuwona funso lanu likudzutsa mafunso awiri: choyamba, zosintha zomwe mumapeza muzochita za lottery, ndipo chachiwiri, zopangira ndi mafotokozedwe ake.
Funso loyamba limakhudzana ndi zolakwika zazikulu za kapangidwe ka zida, kotero tiyeni tiwunikenso zoyambira. Kusintha kwa makwinya kwakanthawi ndi kusintha kwa makulidwe a kapu yamakapu kukuwonetsa kuperewera kwa zida mu station yanu yopita patsogolo.
Pazojambula zakuya, chopandacho chimasungidwa pakati pa chojambula chojambula ndi chosungira chopanda kanthu, pamene nkhonya yojambula imakoka zinthuzo muzojambula, kuzijambula mozungulira malo ozungulira kuti apange chipolopolo. pansi pa kukoka kwa nkhonya yotambasula.Ngati ili yotsika kwambiri, makwinya adzachitika.
Pali malire pakati pa chipolopolo cha chipolopolo ndi m'mimba mwake wopanda kanthu womwe sungathe kupyola ntchito yojambula bwino. Malirewa amasiyana ndi kuchuluka kwa chiwerengero cha zinthu. Lamulo lalikulu ndi 55% mpaka 60% pa kujambula koyamba ndi 20% pa kujambula kulikonse. zofunikira, koma zimakhala zovuta kuonjezera pambuyo pomaliza kupanga).
The opanda kanthu chofukizira kuthamanga p ndi 2.5 N/mm2 zitsulo, 2.0 kuti 2.4 N/mm2 aloyi zamkuwa ndi 1.2 kuti 1.5 N/mm2 aloyi zotayidwa.
Kusiyanasiyana kwa makulidwe a flange kumasonyezanso kuti mapangidwe anu a chida siamphamvu mokwanira.Nsapato za nkhungu zanu ziyenera kukhala zokhuthala mokwanira kuti zipirire kukoka popanda buckling.Thandizo pansi pa nsapato ya kufa liyenera kukhala chitsulo cholimba, ndipo zikhomo zowongolera kufa ziyenera kukhala zazikulu mokwanira kuti ziteteze kusuntha kulikonse kwapamwamba ndi pansi kumafa panthawi yotambasula.
Yang'ananinso nkhani zanu.Ngati zowongolera zosindikizira zatha komanso mosasamala, zilibe kanthu ngati chida chanu ndi champhamvu - simungapambane.Yang'anani chithunzithunzi chosindikizira kuti muwonetsetse kuti kutalika kwa makina osindikizira ndi oona komanso apakati.Tsimikizirani kuti mafuta anu ojambulira amasefedwa bwino komanso osamalidwa bwino, komanso kuti voliyumu yogwiritsira ntchito chida ndi malo amphuno ndizokhazikika.Kusindikiza bwino, kusindikiza bwino ndi kuonetsetsa kuti zonse zili bwino. samalani kwambiri pojambula radii; mawonekedwe awo a geometry ndi pamwamba ayenera kukhala angwiro.
Komanso, pamene makasitomala amakonda kuona 304L ndi muyezo 304 ngati kusinthana, 304L ndi kusankha bwino kwa drawing.L amaimira low carbon, amene amapereka 304L zokolola mphamvu ya 0.2% ya 35 KSI ndi 304 wa 0.2% ya 42 KSI.Ndi 16% mphamvu kumafuna kutsika kwa 3% mphamvu, kuchepetsa zokolola 3 pakufunika 30% mphamvu zokolola ndi zokolola zochepa 0. kukhazikitsa mawonekedwe opangidwa.Ndizosavuta kugwiritsa ntchito.
