Kungofanana neruzha runogona kukanganisa muviri wemunhu, mamwe mafrequency anogona kukanganisa michina yeindasitiri kana vharuvhu yekudzora yakasarudzwa nemazvo, kune njodzi yakawedzerwa yekuvhuvhuta, izvo zvinozotungamira kune ruzha rwakanyanya uye mazinga ekudedera, zvichikonzera kukuvara nekukurumidza kumapaipi emukati neepasi emvura.vharuvhu.
Pamusoro pezvo, ruzha rwakanyanya runowanzo kukonzera kudedera kunogona kukuvadza mapaipi, zvishandiso nezvimwe zvishandisoVharuvhunekufamba kwenguva, kuora kwezvikamu, kuvharika kwevharuvhu kunokonzerwa nehurongwa hwemapaipi hunogona kukuvara zvakanyanya. Kukuvara uku kunonyanya kukonzerwa nesimba reruzha rwekudengenyeka, kukurumidza kwengura uye kuvharika kunoratidzwa neruzha rwakanyanya rwekudengenyeka kukuru kunokonzerwa nekuumbwa nekuputsika kwemabubble emhepo pedyo nepasi pemvura..
Kunyangwe izvi zvinowanzoitika mubhoramavharuvhuuye mavharuvhu anotenderera mumuviri, zvinogona kuitika munguva pfupi, kupora kwakanyanya kufanana nechikamu chemuviri wewafer cheV-ball.vharuvhukunyanyamavharuvhu eshavishavikudivi rezasi revharuvhu apovharuvhuKana paine chinhu chinomanikidzwa munzvimbo imwe chete chinogona kukonzera cavitation, izvo zvinogona kukonzera kubuda kwemvura mumapombi evharuvhu uye kugadziriswa kwewelding, vharuvhu haina kukodzera chikamu ichi chemutsetse.
Pasinei nekuti cavitation inoitika mukati mevharuvhu kana pasi pevharuvhu, michina iri munzvimbo yecavitation ichakuvadzwa zvakanyanya nemafirimu akatetepa, masprings uye zvidimbu zvidiki zve cantilever, kuzununguka kukuru kwe amplitude kunogona kukonzera kuzunguzika. Nzvimbo dzinogara dzichikundikana dzinowanikwa mumidziyo yakaita se pressure gauges, transmitters, thermocouple sleeves, flowmeters, sampling systems. MaActuators, positioners uye limit switches ane masprings achakurumidza kupera, uye ma mounting brackets, fasteners uye connectors zvichasununguka uye zvichakundikana nekuda kwe vibration.
Kuora kwakawanda, kunoitika pakati penzvimbo dzakasakara dzakabatwa nekudedera, kunowanzoitika pedyo nemavharuvhu ekudzivirira. Izvi zvinogadzira ma hard oxides seabrasives kuti kukurumidzise kupera pakati penzvimbo dzakasakara. Midziyo yakakanganiswa inosanganisira kupatsanura uye kutarisa mavharuvhu, kuwedzera kumavharuvhu ekudzora, mapombi, masikirini anotenderera, masamplers uye chero imwe nzira inotenderera kana inotsvedza.
Kudengenyeka kweamplitude yepamusoro kunogonawo kutsemuka nekuparadza zvikamu zvemavharuvhu esimbi nemadziro emapaipi. Zvidimbu zvesimbi zvakapararira kana zvinhu zvinokuvadza zvinogona kusvibisa midziyo iri mupaipi, izvo zvinogona kukanganisa zvakanyanya mapaipi evharuvhu ane hutsanana uye mapaipi emvura akachena kwazvo. Izvi hazvibvumirwiwo.
Kufanotaura nezvekukundikana kwe cavitation kwema plug valves kwakaoma uye hakusi kungoverengerwa kuderera kwekumanikidzwa kwe choke. Zvakaitika zvinoratidza kuti zvinokwanisika kuti kumanikidzwa kuri muhova huru kunodzikira kusimba remvura yemvura isati yatanga kupwanyika kwenzvimbo yacho uye kudonha kwe steam bubble. Vamwe vagadziri vema valvu vanofanotaura kukundikana kwekupenya kwezuva nekukurumidza nekutsanangura kudonha kwekutanga kwekumanikidzwa kwekukuvadzwa. Nzira yekutanga yemugadziri we valvu nekufanotaura kukuvara kwe cavitation yakavakirwa pakuti steam bubbles inodonha, zvichikonzera cavitation uye ruzha. Zvakaonekwa kuti kukuvara kukuru kwe cavitation kuchadziviswa kana ruzha rwakaverengerwa rwuri pasi pemiganhu yakanyorwa pazasi.
Saizi yevharuvhu inosvika masendimita matatu - 80 dB
Saizi yevharuvhu ye 4-6 inches - 85 dB
Saizi yevharuvhu 8-14 inches - 90 dB
Saizi dzevharuvhu dzine masendimita 16 zvichikwira - 95 dB
Nzira dzekubvisa kukuvara kwe cavitation
Dhizaini yakakosha yevharuvhu yekubvisa cavitation inoshandisa kupatsanurwa kwemvura uye kuderedzwa kwekumanikidzwa kwakayerwa:
"Kuchinja mavharuvhu" kunoreva kupatsanura kuyerera kukuru kuita mafungu madiki akati wandei, uye nzira yekuyerera kwevharuvhu yakagadzirwa kuitira kuti kuyerera kupfuure nemumaburi madiki akawanda akafanana. Sezvo chikamu chehukuru hwebhabhu re cavitation chichiverengerwa kuburikidza neburi iro kuyerera kunopfuura naro. Buri diki rinogonesa mabhuru madiki, zvichikonzera ruzha rushoma uye kukuvara kushoma kana zvasvika pakukuvadzwa.
"Kudzikira kwepressure kwakatarwa" zvinoreva kuti vharuvhu yakagadzirwa kuti ive nenzvimbo mbiri kana kupfuura dzekugadzirisa dzakatevedzana, saka pachinzvimbo chekudzikira kwepressure yese mudanho rimwe chete, inotora matanho madiki akati wandei. Kudzikira kwepressure kushoma pane imwe neimwe kunogona kudzivirira kudzvinyirirwa kuri mukudonha kubva mukudzvinyirirwa kwemvura, nokudaro zvichibvisa chiitiko che cavitation muvharuvhu.
Kusanganiswa kwekutsausa uye kudonhedza simba muvharuvhu imwe chete kunobvumira kuvandudzwa kwekudzivirira kwe cavitation kuburikidza. Panguva yekuchinja vharuvhu, kuisa vharuvhu yekudzora uye kumanikidzwa pakupinda kwevharuvhu kwakakwira (semuenzaniso kudivi riri kure kumusoro, kana pakukwirira kwakaderera), dzimwe nguva kubvisa matambudziko e cavitation.
Pamusoro pezvo, kuisa vharuvhu yekudzora panzvimbo yekupisa kwemvura, uye nekudaro kumanikidzwa kwemhepo kwakaderera (senge chinochinja kupisa chedivi rekupisa kwakaderera) zvinogona kubatsira kubvisa matambudziko ekuvhara kwemvura.
Pfupiso yakaratidza kuti chiitiko chekuvharwa kwemavharuvhu hachisi chekungokanganisa mashandiro evharuvhu chete uye kukuvara kwemavharuvhu. Mapaipi nemidziyo zviri panjodziwo. Kufanotaura kuvharwa kwemavharuvhu uye kutora matanho ekuabvisa ndiyo chete nzira yekudzivirira dambudziko remari inodhura yekushandisa mavharuvhu.
