Ndondomeko yokonza munda wa vuto la cavitation la chipinda choyendetsa turbine

Turbine yamadzi ndi makina amphamvu omwe amasintha mphamvu ya madzi kukhala mphamvu ya makina ozungulira. Ndi ya makina a turbine a makina amadzimadzi. Kale kwambiri mu 100 BC, chiyambi cha turbine yamadzi - turbine yamadzi chinaonekera ku China, chomwe chinkagwiritsidwa ntchito kukweza ulimi wothirira ndikuyendetsa zida zopangira tirigu. Ma turbine ambiri amakono amadzi amayikidwa m'malo opangira magetsi kuti ayendetse majenereta kuti apange magetsi. Mu malo opangira magetsi amadzi, madzi omwe ali m'malo osungira madzi amatsogoleredwa ku turbine ya hydraulic kudzera mu chitoliro cha headrace kuti ayendetse turbine runner kuti izungulire ndikuyendetsa jenereta kuti ipange magetsi. Madzi omalizidwa amatulutsidwa kupita pansi kudzera mu chitoliro cha tailrace. Mutu wamadzi ukakhala wapamwamba komanso kutulutsa kwakukulu, mphamvu yotulutsa ya turbine ya hydraulic imakhala yayikulu.
Chida chopangira ma turbine cha tubular chomwe chili pa siteshoni yamagetsi yamadzi chimakhala ndi vuto la cavitation mu chipinda chothamangira cha turbine, chomwe chimapanga cavitation yokhala ndi m'lifupi wa 200mm ndi kuya kwa 1-6mm pa chipinda chothamangira pa malo olowera ndi kutuluka kwa tsamba lomwelo, kuwonetsa malamba a cavitation kuzungulira konse. Makamaka, cavitation yomwe ili pamwamba pa chipinda chothamangira imaonekera kwambiri, yokhala ndi kuya kwa 10-20mm. Zomwe zimayambitsa cavitation mu chipinda chothamangira cha turbine zimasanthulidwa motere:
Chopondera ndi tsamba la siteshoni yamagetsi yamadzi zimapangidwa ndi chitsulo chosapanga dzimbiri, ndipo chinthu chachikulu cha chipinda chopondera ndi Q235. Kulimba kwake komanso kukana kwa cavitation ndi kofooka. Chifukwa cha mphamvu yochepa yosungira madzi m'chitsime, dziwe lakhala likugwira ntchito pamutu wapamwamba kwambiri kwa nthawi yayitali, ndipo thovu zambiri za nthunzi zimawonekera m'madzi akumbuyo. Panthawi yogwira ntchito, madzi amatuluka mu turbine ya hydraulic kudzera m'dera lomwe kuthamanga kuli kotsika kuposa kuthamanga kwa nthunzi. Madzi omwe amadutsa m'malo opingasa a tsamba amatuluka nthunzi ndikuwira kuti apange thovu la nthunzi, zomwe zimapangitsa kuthamanga kwamphamvu kwapafupipafupi, zomwe zimapangitsa kugwedezeka nthawi ndi nthawi pa kuthamanga kwa chitsulo ndi madzi, zomwe zimapangitsa kuti katundu wogwedezeka mobwerezabwereza pamwamba pa chitsulo, zomwe zimapangitsa kuwonongeka kwa zinthu. Zotsatira zake, cavitation yachitsulo imagwa. Cavitation imachitika mobwerezabwereza pa chipinda chopondera pa malo olowera ndi kutuluka kwa tsamba lomwelo. Chifukwa chake, pansi pa kugwira ntchito kwa mutu wamadzi wapamwamba kwambiri kwa nthawi yayitali, cavitation imachitika pang'onopang'ono ndipo imapitirira kuzama.

Pofuna kuthana ndi vuto la cavitation la chipinda choyendetsera turbine, malo opangira magetsi a madzi adakonzedwa ndi kuwotcherera koyambirira, koma vuto lalikulu la cavitation lidapezekanso mchipinda choyendetsera panthawi yokonzanso pambuyo pake. Pankhaniyi, munthu woyang'anira bizinesiyo adatilumikizana ndi chiyembekezo kuti titha kuthandiza kuthetsa vuto la cavitation la chipinda choyendetsera turbine. Mainjiniya athu adapanga dongosolo lokonzekera lokhazikika kutengera kusanthula kwatsatanetsatane kwa zida za kampaniyo. Pamene tikutsimikiza kukula kwa kukonza, tinasankha zipangizo za carbon nano polymer malinga ndi malo ogwirira ntchito a zida kuti tikwaniritse zofunikira zogwirira ntchito kwa nthawi yayitali pansi pa mikhalidwe yogwirira ntchito pamalopo. Njira zokonzera pamalopo ndi izi:
1. Kuchita chithandizo chochotsa mafuta pamwamba pa ziwalo zotsekeka za chipinda chothamangira turbine;
2. Kuchotsa dzimbiri pochotsa mchenga;
3. Sakanizani zinthu za Sorecun nano polymer ndikuziyika pa gawo lomwe likuyenera kukonzedwa;
4. Limbitsani zinthuzo ndikuyang'ana malo okonzera.
