Zvinokonzera uye Mhinduro dzeCavitation muMvura Turbine

1. Zvinokonzera cavitation mumaturbines
Zvikonzero zve cavitation ye turbine yakaoma. Iyo yekumanikidza kugovera mu turbine runner haina kuenzana. Semuenzaniso, kana mumhanyi akaiswa akakwirira zvikuru maererano nepamusoro pemvura yakadzika, apo mvura yakakwirira-inoyerera ichipfuura nepakati-pasi-inodzvinyirira, zviri nyore kusvika kune vaporization pressure uye inogadzira mabhubhu. Kana mvura ichiyerera ichienda kunzvimbo yekudzvinyirirwa kwepamusoro, nekuda kwekuwedzera kwekumanikidza, mabhubhu anodonhedza, uye zvikamu zvemvura inoyerera zvinorova pakati pemabhubhu nekukurumidza kukuru kuzadza voids inogadzirwa neiyo condensation, zvichikonzera yakakura hydraulic impact uye electrochemical action, ichiita Iyo blade inonyungudutswa kuti ibudise makomba uye uchi hwehuchi pores, uye kunyange huchi hwehuchi. Cavitation kukuvadzwa kunogona kutungamira mukuderedzwa kwemidziyo kushanda zvakanaka kana kukuvadza, zvichikonzera mhedzisiro nemhedzisiro.

2. Nhanganyaya kune Nyaya dzeTurbine Cavitation
Sezvo tubular turbine unit ye ​​hydropower station yakaiswa mukushanda, kwave nedambudziko recavitation mukamuri yekumhanya, kunyanya mukamuri yekumhanya painopinza nekubuda kweblade imwe chete, ichigadzira homwe dzemhepo kubva pa200mm muhupamhi uye 1-6mm pakadzika. Iyo cavitation zone pese pese denderedzwa, kunyanya iyo yepamusoro chikamu chemumhanyi chamber, inonyanya kuzivikanwa, uye cavitation yakadzika ndeye 10-20mm. Kunyangwe iyo kambani yakatora nzira dzakadai sekugadzirisa welding, haina kunyatso kudzora iyo cavitation phenomenon. Uye nekufambira mberi kwenguva, makambani mazhinji akabvisa zvishoma nezvishoma iyi nzira yekuchengetedza yechinyakare, saka ndedzipi mhinduro dzinokurumidza uye dzinoshanda?
Parizvino, Soleil kabhoni nano-polymer zvinhu tekinoroji inoshandiswa zvakanyanya kudzora cavitation phenomenon yemvura turbine. Ichi chinyorwa chinhu chinoshanda chakaumbwa nepamusoro-inoshanda resin uye kabhoni nano-inorganic zvinhu kuburikidza nepolymerization tekinoroji. Inogona kunamatira kune akasiyana simbi, kongiri, girazi, PVC, rabha uye zvimwe zvinhu. Mushure mokunge zvinhu zvashandiswa pamusoro pe turbine, hazvina kungoita maitiro ekugadzirisa zvakanaka, asiwo zvine zvakanakira uremu hwechiedza, corrosion resistance, kupfeka kuramba, nezvimwewo, izvo zvinobatsira pakushanda kwakagadzikana kweturbine. Kunyanya yemidziyo inotenderera, simba rekuchengetedza simba richavandudzwa zvakanyanya mushure mekubatanidza kumusoro, uye dambudziko rekurasikirwa kwemagetsi richadzorwa.

Chechitatu, mhinduro kune cavitation ye turbine
1. Ita kurapa kwekubvisa mafuta, tanga shandisa carbon arc air gouging kuronga kubva kune cavitation layer, uye bvisa yakasununguka simbi layer;
2. Zvadaro shandisa sandblasting kubvisa ngura;
3. Yananisa uye shandisa kabhoni nano-polymer zvinhu, uye korobha pamwe chete nebhenji nemutongi wetemplate;
4. Nyaya yacho inorapwa kuti ive nechokwadi chokuti zvinhu zvanyatsopora;
5. Tarisa nzvimbo yakagadziridzwa uye ita kuti ienderane nehukuru hwekutaura.
