Kugenzura urusaku rwa valve, kunanirwa no kubungabunga

Uyu munsi, umwanditsi azakumenyesha uburyo wakemura amakosa asanzwe yo kugenzura valve. Reka turebe!

Ni ibihe bice bigomba kugenzurwa mugihe habaye amakosa?

1. Urukuta rwimbere rwumubiri wa valve

Urukuta rw'imbere rw'umubiri wa valve rukunze kwibasirwa no kwangirika nuburyo bwo kugenzura iyo valve ikoreshwa mugukoresha umuvuduko mwinshi utandukanye kandi utangaza ruswa, bityo rero ni ngombwa kwitondera gusuzuma ruswa hamwe n’umuvuduko ukabije.

2. Intebe

Ubuso bwimbere bwurudodo rutuma intebe ya valve yangirika vuba mugihe valve igenzura ikora, biganisha ku ntebe ya valve ihinduka. Ibi ni ukubera uburyo bwo gucengera. Iyo ugenzura, uzirikane ibi. Intebe ya kashe ya kashe igomba kugenzurwa kugirango yangirike mugihe valve ikora munsi yigitutu gikomeye.

3. Ikirahure

Igikoresho cyo kugenzuraibice byimukanwa iyo biri mubikorwa byitwaindanga. Nicyo itangazamakuru ryangije kandi ryangirika cyane. Buri kintu cyose kigize intanga ngengabihe gikeneye gusuzumwa neza no kwangirika neza mugihe cyo kubungabunga. Twabibutsa ko kwambara kwingirakamaro ya valve (cavitation) birakabije mugihe itandukaniro ryumuvuduko ari ryinshi. Birakenewe gusana intoki ya valve niba yangiritse cyane. Ikigeretse kuri ibyo, ugomba kuzirikana ibintu byose byagereranywa biboneka kumurongo wa valve kimwe nuburyo ubwo aribwo bwose bufitanye isano na valve yibanze.

4. Impeta ya “O” nandi gaseke

Byaba gusaza cyangwa gucika.

5. Gupakira PTFE, amavuta yo gufunga

Byaba bishaje kandi niba ubuso bwashakanye bwangiritse, bigomba gusimburwa nibiba ngombwa.

Igenzura rya valve ritera urusaku, nkore iki?

1. Kuraho urusaku rwa resonance

Ingufu ntizishobora gutwikirwa kugeza igihe valve igenzura yumvikanye, bigatera urusaku rwinshi rurenze 100 dB. Bamwe bafite urusaku ruto ariko kunyeganyega gukomeye, bamwe bafite urusaku rwinshi ariko kunyeganyega gukomeye, mugihe bamwe bafite urusaku rwinshi no kunyeganyega.

Ijwi rimwe gusa, mubisanzwe kuri frequence iri hagati ya 3000 na 7000 Hz, biterwa nuru rusaku. Birumvikana ko urusaku ruzagenda rwonyine niba resonance ikuweho.

2. Kurandura urusaku

Impamvu nyamukuru itera urusaku rwa hydrodynamic ni cavitation. Umuvurungano ukomeye waho hamwe n urusaku rwa cavitation biterwa ningaruka yihuta ibaho mugihe ibibyimba bisenyutse mugihe cya cavitation.

Uru rusaku rufite intera nini kandi nijwi ryumvikana ryibutsa amazi arimo amabuye n'umucanga. Uburyo bumwe bunoze bwo kwikuramo no kugabanya urusaku ni ukugabanya no kugabanya cavitation.

3. Koresha imiyoboro ikikijwe cyane

Uburyo bumwe bwo gukemura inzira yijwi ni ugukoresha imiyoboro ifite inkuta zikomeye. Gukoresha imiyoboro ikikijwe cyane irashobora kugabanya urusaku kuri décibel 0 kugeza kuri 20, mugihe imiyoboro ikikijwe cyane ishobora kongera urusaku kuri décibel 5. Ingaruka zikomeye zo kugabanya urusaku, niko urukuta runini rwumuyoboro wa diametre imwe kandi nini nini ya diameter yuburebure bwurukuta rumwe.

Kurugero, amafaranga yo kugabanya urusaku arashobora -3.5, -2 (ni ukuvuga, yazamuye), 0, 3, na 6 mugihe uburebure bwurukuta rwumuyoboro wa DN200 ari 6.25, 6.75, 8, 10, 12.5, 15, 18, 20 , na 21.5mm. 12, 13, 14, na 14.5 dB. Mubisanzwe, igiciro cyiyongera hamwe nubunini bwurukuta.

4. Koresha ibikoresho bikurura amajwi

Ubu kandi nuburyo bukunzwe kandi bunoze bwo gutunganya inzira zumvikana. Imiyoboro irashobora gupfunyika ibikoresho bikurura amajwi inyuma ya valve n'amasoko y'urusaku.

Ni ngombwa kwibuka ko urusaku rugenda rurerure runyuze mu mazi, bityo gukoresha imiyoboro ikikijwe cyane cyangwa kuzinga ibintu bikurura amajwi ntibizakuraho burundu urusaku.

Bitewe nigiciro cyinshi, ubu buryo burakwiriye cyane kuri ssenariyo aho urusaku ruri hasi kandi uburebure bwimiyoboro ni bugufi.

5.Series muffler

Urusaku rw'indege rushobora kuvaho ukoresheje ubu buryo. Ifite ubushobozi bwo kugabanya neza urwego rwurusaku rwamenyeshejwe kuri bariyeri ikomeye no kurandura urusaku imbere mumazi. Umubare munini utemba cyangwa umuvuduko ukabije wibice bigabanijwe mbere na nyuma ya valve bikwiranye nubukungu bwubu buryo kandi bukora neza.

Absorptive kumurongo ucecekesha nuburyo bwiza bwo guca urusaku. Nubwo bimeze bityo, attenuation isanzwe igarukira kuri 25 dB bitewe nibiciro.

6. Agasanduku kitagira amajwi

Koresha udusanduku tutagira amajwi, amazu ninyubako kugirango utandukanye urusaku rwimbere kandi ugabanye urusaku rwibidukikije hanze kurwego rwemewe.

7. Gukurikirana urukurikirane

Uburyo bwo gutondeka uburyo bukoreshwa mugihe igenzura umuvuduko wa valve ari mwinshi (△ P / P1≥0.8). Ibi bivuze ko igitonyanga cyose cyagabanijwe hagati yikigenzurwa nigikoresho cyagenwe gikurikira inyuma ya valve. Inzira nziza zo kugabanya urusaku ni ukunyura hejuru yamasahani, diffuzeri, nibindi.

Ikwirakwizwa rigomba kuba ryarakozwe hakurikijwe igishushanyo (imiterere yumubiri, ingano) kugirango ikore neza.
