Morteng mhepo turbine inotsvedza mhete zvinhu zvakakosha mumhepo turbine jenareta inobatanidza inotenderera jenareta rotor (kana pitch/yaw system) kune yakamira yekunze dunhu, ine basa rekufambisa simba ikozvino, kudzora masaini, uye data. Vanowanzo shanda munzvimbo dzakaoma uye saka vanowanzotadza. Izvi zvinotevera zvikanganiso zvakajairika uye zvikonzero zvadzo:
1. Slip ring kukuvara kwepamusoro:
Performance: Grooves, zvikwambo, gomba, makwapa anopisa, yakawandisa oxidation layer, uye peeling coating inoonekwa pamusoro pemhete.
Zvinokonzera:
* Kuoma kwebhurashi kwakanyanyisa kana kuti ine tsvina yakaoma.
* Kusabatana kwakashata pakati pebhurashi nenzvimbo yemhete inokonzeresa kukuvara kwemagetsi arc.
* Brush zvimedu kana zvimwe zvimedu zvakaoma (huruva) ichipinda muhuviri hwekukwesha.
* Kusakwana kupfeka kuramba, conductivity, kana corrosion kuramba kweiyo mhete yepamusoro zvinhu.
* Kupisa zvakanyanya nekuda kwekusatonhodza kwakaringana.
* Chemical corrosion (munyu pfapfaidzo, kusvibiswa kwemaindasitiri).
2. Insulation kutadza:
Performance: Rin ring to ring short circuit (ring to ring conduction), ring to ground short circuit, kuderera kwekudzivirira kwekudzivirira, kuwedzera kwekubuda kwemvura, uye mumatambudziko akaoma, midziyo inogumburwa kana kukuvara.
Zvinokonzera:
* Kuchembera, kutsemuka, uye carbonisation yezvinhu zvekudzivirira (epoxy resin, ceramics, nezvimwewo).
* Kuunganidzira kabhoni poda, guruva resimbi, kusvibiswa kwemafuta, kana munyu panzvimbo yekudzivirira ichigadzira nzira dzinofambisa.
* Yakanyanyisa kunyorova kwenzvimbo inokonzeresa kunyura kwehunyoro.
* Kukanganisa kwekugadzira (semuenzaniso, pores, tsvina).
* Overvoltage kana mheni inorova.
3. Kusaonana zvakanaka uye kukwira tembiricha yakanyanyisa:
Performance: Kuwedzera kupikisa kurambana, kuderera kwekutapurirana kwakanaka; kusagadzikana kwenzvimbo kana kukwira kwekushisa kwese (nzvimbo dzinopisa dzinoonekwa nekuona infrared); zvinogona kukonzera maaramu ekupisa kana kunyange moto.
Zvinokonzera:
* Kusakwana kwebhurashi kudzvanywa kana kutadza kwechirimo.
* Kusakwana kwekuonana nzvimbo pakati pebhurashi uye mhete pamusoro (kupfeka zvisina kuenzana, kuisirwa zvisina kunaka).
* Oxidation kana kusvibiswa kweiyo mhete yepamusoro inotungamira kukuwedzera kubata kuramba.
* Yakasununguka mabhaudhi ekubatanidza.
* Kuwedzeredza kushanda.
* Yakavharwa kupisa kupisa nzira kana kutonhora system kutadza (semuenzaniso, kumisa fan).
