1. Wedzera kuoma

Kune oscillations uye zvishoma vibrations, kuoma kunogona kuwedzerwa kubvisa kana kuderedza. Semuenzaniso, kushandisa chitubu chine kuoma kukuru kana kushandisa piston actuator zvinogoneka.

2. Wedzera kunyorova

Kuwedzera kunyorova kunoreva kuwedzera kukweshera kunopesana nekudengenyeka. Semuenzaniso, plug yevharuvhu yevharuvhu inogona kuvharwa ne "O" mhete, kana graphite filler ine friction yakakura, iyo inogona kuita rimwe basa mukubvisa kana kunetesa kudengenyeka kudiki.

3. Wedzera saizi yemutungamiri uye uderedze gap yakakodzera

Saizi yegwaro reshaft plug mavharuvhukazhinji idiki, uye mavharuvhu anofananidzwa akakura, kubva pa 0.4 kusvika 1 mm, iyo inobatsira mukugadzira mechanical vibration. Naizvozvo, kana kudikidikika kwemechanic vibration kukaitika, iyo vibration inogona kudzikiswa nekuwedzera saizi yekutungamira uye nekudzikisa gap rakakodzera.

4. Shandura chimiro che throttle kubvisa resonance

Nekuti iyo inonzi vibration sosi yekudzora vharafuinoitika pachiteshi che throttle apo kuyerera kwepamusoro-kumhanya uye kudzvinyirirwa kunoshanduka nokukurumidza, kushandura chimiro chenhengo ye throttle inogona kuchinja kuwanda kweiyo vibration source, iyo iri nyore kugadzirisa kana resonance isina kusimba.

Iyo chaiyo nzira ndeyekushandura iyo yakakomberedzwa pamusoro peiyo valve core ne 0.5 ~ 1.0mm mukati meiyo vibration yekuvhura renji. Somuenzaniso, aself-operated pressure regulating valveinoiswa pedyo nenzvimbo yemhuri yefekitari. Kurira kwemuridzo kunokonzerwa neresonance kunobata vamwe vese vashandi. Mushure mevhavha yepakati pepamusoro yabviswa ne 0.5mm, ruzha rwemuridzo runonyangarika.

5. Dzorera chikamu chinoputika kuti ubvise resonance

Nzira dzacho ndeidzi:

Shandura maitiro ekuyerera, logarithmic kune mutsara, mutsara kune logarithmic;

Tsiva iyo valve yepakati fomu. Semuenzaniso, shandura shaft plug yemhando ye "V"-shaped groove valve core, uye shandura shaft plug yemhando yevhavha yezvigaro zviviri kune imwe sleeve;

Shandura sleeve yehwindo kune sleeve ine maburi madiki, nezvimwe.

Semuyenzaniso, vharafu yeDN25 ine zvigaro zviviri mugirodhi yefetereza yaiwanzozunguzika nekutyoka pakubatana pakati pehunde yevharuvhu nepakati pevharuvhu. Mushure mekunge tasimbisa kuti yaive resonance, takashandura mutsara hunhu hwevhavha core kuita logarithmic valve core, uye dambudziko rakagadziriswa. Mumwe muenzaniso ndeyeDN200 sleeve valve inoshandiswa murabhoritari yekoreji yekubhururuka nendege. Iyo plug yevharuvhu yakatenderedzwa zvine simba uye haina kukwanisa kushandiswa. Mushure mekushandura sleeve nehwindo kune sleeve ine gomba duku, kutenderera kwakabva kwanyangarika.

6. Shandura rudzi rwevhavha inogadzirisa kubvisa resonance

Iwo echisikigo mafambisirwo ekudzora mavharuvhu ane akasiyana maumbirwo mafomu akasiyana. Kuchinja rudzi rwevharuvhu yekudzora ndiyo inonyanya kushanda nzira yekubvisa resonance.

Iro resonance yevhavha yakaoma zvikuru panguva yekushandiswa - inodedera zvakasimba (muzviitiko zvakakomba, valve inogona kuparadzwa), inotenderera zvakasimba (kunyange tsinde yevhavha inozununguka kana kumonyoroka), uye inobudisa ruzha rwakasimba (kusvika kunopfuura 100 decibels. ) Ingotsiva vharafu nevhavha ine mutsauko mukuru wehutano, uye mugumisiro uchava pakarepo, uye resonance yakasimba ichanyangarika nenzira inoshamisa.

Semuenzaniso, DN200 sleeve valve inosarudzirwa chirongwa chitsva chekuwedzera fekitori yevinylon. Zvitatu zviri pamusoro zviriko. Iyo DN300 pombi inosvetuka, plug yevharuvhu inotenderera, ruzha runopfuura zana decibels, uye resonance kuvhura i20 kusvika 70%. Chimbofunga nezvekuvhurwa kweresonance. Dhigirii rakakura. Mushure mekushandisa vhavha yezvigaro zviviri, resonance yakanyangarika uye kushanda kwaive kwakajairika.

7. Nzira yekudzikisa cavitation vibration

Kune iyo cavitation vibration inokonzerwa nekudonha kwecavitation bubbles, ndezvemuzvarirwo kutsvaga nzira dzekudzikisa cavitation.

Simba rekuita rinogadzirwa nekuputika kwebubble harina kuitwa panzvimbo yakasimba, kunyanya iyo valve core, asi inotorwa nemvura. Sleeve mavharuvhu ane chinhu ichi, saka shaft plug yemhando yevharuvhu core inogona kuchinjwa kuita sleeve type.

Tora matanho ese ekudzikisa cavitation, senge kuwedzera throttling kuramba, kuwedzera constriction orifice pressure, yakarongwa kana yakatevedzana kudzvinyirirwa kuderedza, nezvimwe.

8. Dzivisa vibration sosi wave kurwisa nzira

Wave shock kubva kune ekunze vibration sosi inokonzeresa kuzununguka kwevharuvhu, icho chiri pachena chimwe chinhu chinofanira kudzivirirwa panguva yakajairika kushanda kwevhavha inoronga. Kana kudedera kwakadaro kukaitika, matanho anowirirana anofanira kutorwa.
