1. Wonjezerani kuuma

Kwa oscillations ndi kugwedezeka pang'ono, kuuma kungathe kuwonjezeka kuti kuthetse kapena kufooketsa. Mwachitsanzo, kugwiritsa ntchito kasupe wokhala ndi kuuma kwakukulu kapena kugwiritsa ntchito pisitoni actuator ndizotheka.

2. Wonjezerani damping

Kuchuluka kwa chinyezi kumatanthauza kukulitsa kukangana motsutsana ndi kugwedezeka. Mwachitsanzo, pulagi ya valve ya valve ya manja imatha kusindikizidwa ndi mphete ya "O", kapena graphite filler yokhala ndi mikangano yayikulu, yomwe imatha kuchitapo kanthu pochotsa kapena kufooketsa kugwedezeka pang'ono.

3. Wonjezerani kukula kwa kalozera ndikuchepetsa kusiyana koyenera

Kukula kwa kalozera wama valve a shaftnthawi zambiri imakhala yaying'ono, ndipo chilolezo chofananira cha mavavu onse nthawi zambiri chimakhala chachikulu, kuyambira 0.4 mpaka 1 mm, chomwe chimathandiza kupanga kugwedezeka kwamakina. Chifukwa chake, kugwedezeka pang'ono kwamakina kumachitika, kugwedezekako kumatha kufooketsedwa powonjezera kukula kwa wowongolera ndikuchepetsa kusiyana koyenera.

4. Sinthani mawonekedwe a throttle kuchotsa resonance

Chifukwa otchedwa kugwedera gwero lavalve yoyendetsazimachitika pa doko throttle kumene kuthamanga kwachangu ndi kupanikizika kumasintha mofulumira, kusintha mawonekedwe a membala wa throttle angasinthe mafupipafupi a gwero la kugwedezeka, zomwe zimakhala zosavuta kuthetsa pamene resonance ilibe mphamvu.

Njira yeniyeni ndiyo kutembenuza pamwamba pazitsulo za valve ndi 0.5 ~ 1.0mm mkati mwa kugwedezeka kwa kutsegula. Mwachitsanzo, avalavu yodzipangira yokha kuthamangaimayikidwa pafupi ndi dera la banja la fakitale. Phokoso la mluzu lobwera chifukwa cha kumveka bwino limakhudza antchito ena onse. Pambuyo pakutembenuzidwa kwapakati pa valavu ndi 0.5mm, phokoso la mluzu limasowa.

5. Bwezerani gawo logwedeza kuti muchotse resonance

Njira zake ndi:

Sinthani mawonekedwe oyenda, logarithmic kukhala mzere, mzere kukhala logarithmic;

Bwezerani mawonekedwe apakati a valve. Mwachitsanzo, sinthani mtundu wa pulagi ya shaft kukhala pachimake cha "V", ndikusintha mtundu wa pulagi ya shaft ya valavu yokhala ndi mipando iwiri kukhala mtundu wa manja;

Sinthani manja a zenera kukhala manja okhala ndi mabowo ang'onoang'ono, etc.

Mwachitsanzo, valavu ya DN25 yokhala ndi mipando iwiri mu chomera cha feteleza wa nayitrogeni nthawi zambiri imanjenjemera ndikusweka pakulumikizana pakati pa tsinde la valavu ndi pachimake cha valve. Titatsimikizira kuti ndi resonance, tidasintha mzere wa valve kukhala pachimake cha logarithmic valve, ndipo vutoli linathetsedwa. Chitsanzo china ndi valavu ya manja ya DN200 yomwe imagwiritsidwa ntchito mu labotale ya koleji yoyendetsa ndege. Pulagi ya valavu inazunguliridwa mwamphamvu ndipo sinathe kugwiritsidwa ntchito. Pambuyo posintha malaya ndi zenera ku manja okhala ndi dzenje laling'ono, kuzungulirako kunasowa.

6. Sinthani mtundu wa valve yowongolera kuti muchotse resonance

Ma frequency achilengedwe a ma valve owongolera okhala ndi mawonekedwe osiyanasiyana amasiyana mwachilengedwe. Kusintha mtundu wa valavu yowongolera ndiyo njira yabwino kwambiri yochotsera resonance.

Kumveka kwa valve kumakhala koopsa kwambiri pakagwiritsidwa ntchito - kumagwedezeka kwambiri (pazovuta kwambiri, valve ikhoza kuwonongedwa), imazungulira mwamphamvu (ngakhale tsinde la valve likugwedezeka kapena kupindika), ndipo limapanga phokoso lamphamvu (mpaka ma decibel oposa 100). ). Ingolowetsani valavu ndi valavu yokhala ndi kusiyana kwakukulu kwapangidwe, ndipo zotsatira zake zidzakhala nthawi yomweyo, ndipo mphamvu yamphamvu idzazimiririka mozizwitsa.

Mwachitsanzo, valavu ya manja ya DN200 imasankhidwa pulojekiti yatsopano yokulitsa fakitale ya vinylon. Zochitika zitatu zapamwambazi zilipo. Chitoliro cha DN300 chikudumpha, pulagi ya valve imazungulira, phokoso limaposa ma decibel 100, ndipo kutsegula kwa resonance ndi 20 mpaka 70%. Taganizirani kutsegulidwa kwa resonance. Digiriyi ndi yayikulu. Pambuyo pogwiritsira ntchito valve yokhala ndi mipando iwiri, resonance inasowa ndipo ntchitoyo inali yachibadwa.

7. Njira yochepetsera kugwedezeka kwa cavitation

Pakuti cavitation kugwedera chifukwa cha kugwa kwa cavitation thovu, mwachibadwa kupeza njira kuchepetsa cavitation.

Mphamvu mphamvu kwaiye ndi kuwira kuphulika si anachita pa olimba pamwamba, makamaka valavu pachimake, koma odzipereka ndi madzi. Mavavu a manja ali ndi izi, kotero kuti shaft plug mtundu wa valve core ukhoza kusinthidwa kukhala mtundu wa manja.

Tengani njira zonse kuti muchepetse cavitation, monga kukulitsa kukana kwa throttling, kukulitsa kupsinjika kwa orifice, kutsika kapena kutsika kwapang'onopang'ono, etc.

8. Pewani kugwedera gwero yoweyula kuukira njira

Kugwedezeka kwa mafunde kuchokera kumagwero akunja ogwedezeka kumayambitsa kugwedezeka kwa valve, zomwe mwachiwonekere ndi chinthu chomwe chiyenera kupewedwa panthawi yomwe valve yoyendetsera ntchito ikugwira ntchito. Ngati kugwedezeka kotereku kumachitika, njira zofananira ziyenera kuchitidwa.
