Monga momwe mawu amatha kukhala ndi zotsatira zoyipa pa thupi la munthu, maulendo ena amatha kusewera pa zida za mafakitale akasankhidwa bwino, pali chiopsezo chowonjezereka cha capetation ndi kuwonongeka kwamphamvu kwambiri kwavalavu.

Kuphatikiza apo, kuchuluka kwa phokoso kwambiri nthawi zambiri kumayambitsa kugwedeza mapaipi, zida ndi zida zinaValavuNdi kupita kwa nthawi, kuwonongeka kwa zigawo zikuluzikulu, valavu ya masitepe oyambitsidwa ndi ma piperine omwe amakonda kuwonongeka kwambiri. Zowonongekazi zimayamba chifukwa cha kuchuluka kwa phokoso, kuthamanga kwamphamvu ndi kaphikidwe kambiri kwa phokoso lalikulu la matalikidwe ndikuwonongeka.

Ngakhale izi zimachitika mu mpiramavuvundi mavuvu amphaka, zimatha kuchira kwakanthawi, kopambana kofanana ndi gawo la thupi la Vvalavu, makamakaMavalidwe a Gulugufekumbali yakugwa kwa valavu pomwevalavuAmapanikizika pamalo amodzi omwe amangokonda kuyika pa cavit phenomenon, womwe umakonda kutayikira bwino kwambiri ndikukonzanso, valavu sioyenera gawo ili la mzere.

Mosasamala kanthu za Cavitation imachitika mkati mwa valavu, zida zamagalimoto opyapsa zidzakhala zowonongeka kwa mafilimu a usrat, kugwedezeka kwakukulu kwa mascisillations. Mfundo zoletsedwa pafupipafupi monga zida zokhala ngati zigawo, zopatsirana, mabatani a therming, oyendetsa mabatani amazimitsa ndikulephera chifukwa cha kugwedezeka ndikulephera chifukwa cha kugwedezeka.

Kukhumudwa kwa Corlosion, komwe kumachitika pakati pa malo ovala bwino kugwedezeka, ndi wamba pafupi ndi mavuvu. Izi zimabweretsa ma oxide ozizira ngati Abrasies kuti athandizire kuvala zovala zamkati. Zida zakhudzidwa zimaphatikizapo kudzipatula ndikumayang'ana mavesi, kuwonjezera pa mavavu, mapampu, zowombera zozungulira, ziwonetsero ndi njira ina iliyonse yosinthira.

Kugwedezeka kwambiri kumatha kusweka ndi ma vall valani yachitsulo ndi makhoma. Tizilombo tating'onoting'ono tomwe timabalalika kapena zida zowononga mphamvu zimatha kuipitsa media mu paipi, yomwe imatha kukhala yovuta kwambiri pa valavu yaubweya yoyera komanso yoyera yoyera. Izi siziloledwa.

Kuneneratu za kulephera kwa cavittit kwa ma valve ndi zovuta kwambiri ndipo sikungowerengeredwa kutsamira kutsamira. Zochitika zikuwonetsa kuti ndizotheka kuti kukakamizidwa mu mtsinje waukulu kumatsindika kwa madzi osokoneza bongo am'deralo ndi kugwa kwa nthunzi. Opanga ena a valavu ena amaneneratu za kukula kwa emlipse pofotokozera zowonongeka koyamba. Njira yopangira wopanga ma valve poyambira kuwonongeka kwa Cavitation imachokera kuti thovu lamitsempha igwera, ndikuyambitsa cavitation ndi phokoso. Zakhala zikutsimikizika kuti kuwonongeka kofunikira pagalimoto kudzapewedwa ngati gawo lowerengera lili pansi pa malire omwe ali pansipa.

Kukula kwa valavu mpaka mainchesi atatu - 80 DB

Kukula kwa valavu ya 4-6 - 85 DB

Kukula kwa valavu 8-14 mainchesi - 90 DB

Valavuni ndi mainchesi 16 ndi akulu - 95 DB

Njira Zothetsa Kuwonongeka kwa Cavitati

Mapangidwe apadera apadera kuti athetse cavitation amagwiritsa ntchito sprit yogawanika ndi kuponderezedwa kwake:
"Valavu Yosiyanasiyana" ndikugawa kutuluka kwakukulu mu kayendedwe kakang'ono kakang'ono, ndipo njira yoyenda imapangidwira kuti kutuluka kadulidwe kambiri kofanana. Kuyambira gawo la kukula kwa cholembera cha cavitting chimawerengedwa kudzera pakutseguka komwe kumatuluka. Kutseguka kakang'ono kumathandizira thovu laling'ono, lomwe limapangitsa phokoso laling'ono komanso kuwonongeka pang'ono pakawonongeka.

"Kupanikizika kwapakati pa" kumatanthauza kuti valavu imapangidwa kuti ikhale ndi zosintha ziwiri kapena zingapo mosintha, ndiye m'malo mopanikizika kwathunthu ndikutsika gawo limodzi, zimatenga njira zingapo zazing'ono. Poyerekeza ndi kusunthira kwamunthu payekha kungalepheretse kukakamiza kwa shra, motero kuchotsa pakhungu la valavu.

Kuphatikiza kwa kusanja ndi kukakamizidwa kukulepheretsani mu valavu yomweyi imalola kukana kwabwino kwambiri. Pa kusintha kwa valavu, kuyika valavu yowongolera komanso kupanikizika kokomera valavu kuli kokwera (mwachitsanzo, mbali yotsika), nthawi zina imathetsa mavuto ochepetsa.

Kuphatikizanso

Chidule chawonetsa kuti ma cavitation phenomenon a mavuvu sakhala ongonyansa ndi kuwonongeka kwa mavalidwe. Mapaipi ndi zida ndi zida zilinso pachiwopsezo. Kulosera za patali ndi kuchitapo kanthu kuti tithetse njira yokhayo yopewera vuto la kugwiritsa ntchito ndalama zodula.
