1. Eketsa ho satalla

Bakeng sa li-oscillations le ho sisinyeha hanyenyane, ho satalla ho ka eketsoa ho e felisa kapa ho e fokolisa.Ka mohlala, ho ka khoneha ho sebelisa seliba se nang le boima bo boholo kapa ho sebelisa mochine oa piston.

2. Eketsa damping

Ho eketsa mongobo ho bolela ho eketsa khohlano khahlanong le vibrate.Ka mohlala, plug ea valve ea valve ea sleeve e ka tiisoa ka lesale la "O", kapa graphite filler e nang le likhohlano tse kholo, tse ka bapalang karolo e itseng ho felisa kapa ho fokolisa ho thothomela ho honyenyane.

3. Eketsa boholo ba tataiso le ho fokotsa lekhalo le loketseng

Boholo ba tataiso eali-valve tsa plug tsa shaftka kakaretso e nyane, 'me tumello e ts'oanang ea li-valve kaofela hangata e kholo, ho tloha ho 0.4 ho isa ho 1 mm, e thusang ho hlahisa ho sisinyeha ha mechine.Ka hona, ha ho sisinyeha ho fokolang ha mochine ho etsahala, ho sisinyeha ho ka fokotsoa ka ho eketsa boholo ba tataiso le ho fokotsa lekhalo le loketseng.

4. Fetola sebopeho sa throttle ho felisa resonance

Hobane seo ho thoeng ke vibration mohloli oabelofo e laolange etsahala boema-kepeng ba throttle moo phallo e phahameng ea lebelo le khatello e fetohang ka potlako, ho fetola sebōpeho sa setho sa throttle ho ka fetola makhetlo a mangata a mohloli oa vibration, oo ho leng bonolo ho o rarolla ha resonance e se matla.

Mokhoa o ikhethileng ke ho fetola bokaholimo bo kobehileng ba mokokotlo oa valve ka 0.5 ~ 1.0mm ka har'a sebaka sa ho bula ho thothomela.Ka mohlala, avalve e laolang khatello e ikemetsenge kenngoa haufi le sebaka sa lelapa sa fektheri.Molumo oa mololi o bakoang ke molumo o ama basebetsi ba bang kaofela.Kamora hore karolo ea mantlha ea valve e tlosoe ka 0.5mm, molumo oa mololi oa resonance oa nyamela.

5. Kenya sebaka sa karolo ea throttling ho felisa resonance

Mekhoa ke:

Fetola litšobotsi tsa phallo, logarithmic ho ea ho linear, linear to logarithmic;

Fetola foromo ea mantlha ea valve.Ka mohlala, fetola mofuta oa plug ea shaft ho "V"-shaped groove valve core, 'me u fetole mofuta oa plug ea shaft oa valve ea litulo tse peli ho ea ho mofuta oa letsoho;

Fetola sleeve ea fensetere ho sleeve e nang le masoba a manyenyane, joalo-joalo.

Mohlala, valve ea DN25 e nang le litulo tse peli semeleng sa manyolo a naetrojene e ne e atisa ho sisinyeha le ho robeha ha ho hokahanngoa pakeng tsa kutu ea valve le motheo oa valve.Ka mor'a hore re netefatse hore e ne e le resonance, re ile ra fetola motsoako oa li-valve ho ea ho logarithmic valve core, 'me bothata bo ile ba rarolloa.Mohlala o mong ke valve ea letsoho ea DN200 e sebelisoang laboratoring ea koleche ea lifofane.Pula ea valve e ile ea potoloha ka matla 'me e ne e sitoa ho sebelisoa.Ka mor'a ho fetola sleeve ka fensetere ho sleeve e nang le lesoba le lenyenyane, ho potoloha hang-hang ho ile ha nyamela.

6. Fetola mofuta oa valve e laolang ho felisa resonance

Maqhubu a tlhaho a li-valve tse laolang tse nang le mefuta e fapaneng ea sebopeho li fapane ka tlhaho.Ho fetola mofuta oa li-valve tse laolang ke tsela e sebetsang ka ho fetisisa ea ho felisa resonance.

Resonance ea valve e matla haholo nakong ea ts'ebeliso - e sisinyeha ka matla (maemong a matla, valve e ka senyeha), e potoloha ka matla (esita le stem ea valve e sisinyeha kapa e sothehile), 'me e hlahisa lerata le matla (ho fihlela ho feta 100 decibels). ).Feela nka sebaka sa valve ka valve e nang le phapang e kholoanyane ea sebopeho, 'me phello e tla ba hang-hang,' me resonance e matla e tla nyamela ka mohlolo.

Ka mohlala, valve ea Sleeve ea DN200 e khethiloe bakeng sa morero o mocha oa ho atolosa fektheri ea vinylon.Lintho tse tharo tse ka holimo li teng.Pipe ea DN300 e qhoma, plug ea valve ea potoloha, lerata le feta li-decibel tse 100, 'me ho buleha ha resonance ke 20 ho isa ho 70%.Nahana ka ho bula molumo oa molumo.Degree e kholo.Ka mor'a ho sebelisa valve ea litulo tse peli, resonance e ile ea nyamela 'me opereishene e ne e tloaelehile.

7. Mokhoa oa ho fokotsa ho thothomela ha cavitation

Bakeng sa ho sisinyeha ha cavitation ho bakoang ke ho putlama ha li-bubble tsa cavitation, ke tlhaho ho fumana litsela tsa ho fokotsa cavitation.

Matla a tšusumetso a hlahisoang ke ho phatloha ha bubble ha a sebetse holim'a metsi a tiileng, haholo-holo mokokotlo oa valve, empa a kenngoa ke mokelikeli.Li-valve tsa letsoho li na le tšobotsi ena, kahoo "valve" ea mofuta oa shaft plug e ka fetoloa ho ba mofuta oa letsoho.

Nka mehato eohle ea ho fokotsa cavitation, joalo ka ho eketsa khanyetso ea throttling, ho eketsa khatello ea orifice ea constriction, ho fokotsa khatello ea sethaleng kapa letoto, joalo-joalo.

8. Qoba mokhoa oa tlhaselo ea maqhubu a mohloli oa vibrate

Ho thothomela ha maqhubu ho tsoa mehloling ea kantle ea ho sisinyeha ho baka ho sisinyeha ha valve, e leng ntho e lokelang ho qojoa nakong ea ts'ebetso e tloaelehileng ea valve e laolang.Haeba ho sisinyeha ho joalo ho etsahala, mehato e lumellanang e lokela ho nkoa.
