Pērā i te pānga kino o te oro ki te tinana tangata, ka taea hoki e ētahi auau te whakararu i ngā taputapu ahumahi ina whiriwhiria tika te takirere whakahaere, ka nui ake te tūponotanga o te cavitation, ka hua ake he haruru nui me te wiri, ka tere te pakaru o ngā paipa o roto me raro o te...takirere.
Hei tāpiritanga, ko te nui o te haruru ka puta he wiri ka kino pea ngā paipa, ngā taputapu me ētahi atu taputapu.TakirereI te roanga o te wā, ka pakaru ngā wāhanga, ka puta te pakaru o te takirere i te pūnaha paipa, ā, ka pāngia kinotia. Ko te nuinga o tēnei kino ka puta mai i te kaha haruru wiri, te tere o te tukanga waikura me te pakaru e whakaatahia ana e te taumata haruru teitei o te wiri nui e puta mai ana i te hanganga me te hinganga o ngā mirumiru mamaoa e tata ana me raro iho o te whakahekenga..
Ahakoa he maha ngā wā ka puta tēnei i roto i te pōrongā takirereme ngā takirere hurihuri i roto i te tinana, ka taea e ia te puta i roto i te whakaoranga poto, teitei rite ki te wāhanga tinana wafer o te pōro-Vtakirere, inā koangā takirere pūrerehuai te taha whakararo o te takirere inatakireremēnā ka pēhia i te tūranga kotahi, ka pāngia e te cavitation, ka pāngia e te turuturu i roto i ngā paipa takirere me te whakatikatika i te whakarewa, kāore te takirere e tika mō tēnei wāhanga o te raina.
Ahakoa kei roto i te takirere, kei raro rānei i te takirere te cavitation, ka nui te kino o ngā taputapu i roto i te wāhi cavitation ki ngā kiriata tino-angiangi, ngā puna me ngā hanganga cantilever wāhanga iti, ka taea e ngā wiri nui te whakaoho i ngā oscillations. Ka kitea ngā wāhi pakaru pinepine i roto i ngā taputapu pēnei i ngā ine pēhanga, ngā tuku, ngā ringaringa thermocouple, ngā mita rere, ngā pūnaha tauira. Ka tere te pakaru o ngā actuators, ngā positioners me ngā pana rohe kei roto ngā puna, ā, ka wetekina, ka pakaru hoki ngā whīra whakairi, ngā here me ngā hononga nā te wiri.
He mea noa te waikura o te fretting, e puta ana i waenga i ngā mata kua pakaru e pāngia ana e te wiri, i te taha o ngā takirere cavitation. Ka puta mai i tēnei ngā waikura mārō hei mea whakakoi hei whakatere i te pakaru i waenga i ngā mata kua pakaru. Kei roto i ngā taputapu e pāngia ana ko ngā takirere wehe me ngā takirere tirotiro, me ngā takirere whakahaere, ngā papu, ngā mata hurihuri, ngā tauira me tētahi atu tikanga hurihuri, reti rānei.
Ka taea hoki e ngā wiri kaha te pakaru me te waikura i ngā wāhanga takirere whakarewa me ngā pakitara paipa. Ka taea e ngā matūriki whakarewa marara, ngā rauemi matū waikura rānei te whakapoke i ngā mea kei roto i te paipa, ka pā kino pea tēnei ki ngā paipa takirere akuaku me ngā mea parakore. Kāore hoki e whakaaetia tēnei.
He uaua ake te matapae i te rahunga o te cavitation o ngā takirere mono, ehara i te mea he tatau noa i te hekenga pēhanga kōpiko. E whakaatu ana ngā wheako tera pea ka heke te pēhanga i roto i te awa matua ki te pēhanga kohu o te wai i mua i te mimiti o te rohe me te hinganga o te mirumiru mamaoa. Ka matapaetia e ētahi kaihanga takirere te rahunga o te eclipse wawe mā te tautuhi i te hekenga pēhanga kino tuatahi. Ko te tikanga tīmatanga a te kaihanga takirere mā te matapae i te kino o te cavitation e ahu mai ana i te meka ka hinga ngā mirumiru mamaoa, ka puta te cavitation me te haruru. Kua whakatauhia ka karohia te kino nui o te cavitation mena kei raro iho i ngā rohe kua whakarārangihia i raro nei te taumata haruru kua tatauhia.
Rahi takirere tae atu ki te 3 inihi – 80 dB
Rahi o te takirere 4-6 inihi – 85 dB
Rahi takirere 8-14 inihi – 90 dB
Ngā rahi o ngā takirere 16 inihi me te nui ake – 95 dB
Ngā tikanga hei whakakore i te kino o te cavitation
Ko te hoahoa takirere motuhake hei whakakore i te cavitation e whakamahi ana i te rere wehewehe me te maturuturunga pēhanga kua whakarōpūtia:
Ko te "whakarerekētanga takirere" he wehewehe i te rere nui kia maha ngā rere iti, ā, ka hangaia te ara rere o te takirere kia rere te rere mā roto i ētahi pūaha iti whakarara. Nā te mea ka tatauhia te wāhanga o te rahi o te mirumiru cavitation mā roto i te pūaha e haere ana te rere. Mā te pūaha iti ka taea ai ngā mirumiru iti, ka iti ake te haruru me te kino ina tae mai ki te kino.
Ko te tikanga o te "hekenga pēhanga whakarōpū" he mea hanga te takirere kia rua, neke atu rānei ngā pūwāhi whakatikatika i roto i te raupapa, nō reira, kaua e heke katoa te pēhanga i te taahiraa kotahi, engari he maha ngā taahiraa iti ake. Mā te iti iho i te hekenga pēhanga takitahi ka ārai i te hekenga o te pēhanga i roto i te whakahekenga o te pēhanga kohu o te wai, ā, ka kore ai e puta te āhua o te cavitation i roto i te takirere.
Mā te whakakotahitanga o te tahuritanga me te whakatakoto i te taumata o te hekenga pēhanga i roto i te takirere kotahi ka taea te whakapai ake i te ātete ki te cavitation mā te. I te wā e whakarerekētia ana te takirere, ka teitei ake te whakanoho i te takirere whakahaere me te pēhanga i te tomokanga o te takirere (hei tauira, i te taha whakarunga ake, i te teitei iti iho rānei), i ētahi wā ka kore e raru te cavitation.
Hei tāpiritanga, mā te whakanoho i te takirere whakahaere ki te wāhi o te pāmahana wai, me te pēhanga iti o te kohu (pērā i te whakawhiti wera taha pāmahana iti) ka āwhina i te whakakore i ngā raruraru cavitation.
Kua whakaatuhia e te whakarāpopototanga ko te āhuatanga cavitation o ngā takirere ehara i te mea ko te ngoikore o te mahi me te kino o ngā takirere anake. Kei te mōrearea hoki ngā paipa me ngā taputapu o raro. Ko te matapae i te cavitation me te mahi i ngā mahi hei whakakore i tēnei mea ko te huarahi anake hei karo i te raruraru o ngā whakapaunga utu nui o te whakamahi takirere.
