1. Khulisa ukuqina

Ukuze uthole ama-oscillations kanye nokudlidliza okuncane, ukuqina kungandiswa ukuze kuqedwe noma kukwenze buthaka. Isibonelo, ukusebenzisa isiphethu esinokuqina okukhulu noma ukusebenzisa i-piston actuator kungenzeka.

2. Khulisa ukumanzisa

Ukwenyusa ukumanzisa kusho ukukhulisa ukungqubuzana ngokumelene nokudlidliza. Isibonelo, ipulaki yevalvu yevalvu yomkhono ingavalwa ngendandatho ethi “O”, noma isigcwalisi se-graphite esinokungqubuzana okukhulu, okungadlala indima ethile ekuqedeni noma ekwenzeni buthaka ukundindizela okuncane.

3. Khulisa usayizi womhlahlandlela futhi unciphise igebe elifanele

Usayizi womhlahlandlela weama-valve epulaki ye-shaftngokuvamile kuncane, futhi imvume efanayo yawo wonke ama-valve ngokuvamile inkulu, kusukela ku-0.4 kuya ku-1 mm, okuwusizo ekukhiqizeni ukudlidliza komshini. Ngakho-ke, lapho ukudlidliza komshini okuncane kwenzeka, ukudlidliza kungenziwa buthaka ngokwandisa usayizi womhlahlandlela kanye nokunciphisa igebe elifanelekile.

4. Shintsha ukuma kwe-throttle ukuze uqede i-resonance

Ngoba umthombo okuthiwa vibration wei-valve yokulawulakwenzeka ku-throttle port lapho ukugeleza kwesivinini esiphezulu nokucindezela kushintsha ngokushesha, ukushintsha ukuma kwelungu le-throttle kungashintsha imvamisa yomthombo wokudlidliza, okulula ukukuxazulula lapho i-resonance ingaqinile.

Indlela eqondile iwukuguqula indawo egobile yomgogodla wevalvu ngo-0.5~1.0mm ngaphakathi kwebanga lokuvula ukudlidliza. Ngokwesibonelo, ai-valve yokulawula ingcindezi ezisebenza yonaifakwe eduze kwendawo yomndeni yefekthri. Umsindo wekhwelo obangelwa ukukhala uthinta bonke abanye abasebenzi. Ngemuva kokuthi i-valve core surface ijikiswe ngo-0.5mm, umsindo we-resonance wokushaya ikhwela uyanyamalala.

5. Faka esikhundleni ingxenye edonsayo ukuze uqede ukuzwakala kwe-resonance

Izindlela yilezi:

Shintsha izici zokugeleza, i-logarithmic iye komugqa, umugqa uye ku-logarithmic;

Shintshanisa i-valve core form. Isibonelo, shintsha uhlobo lwepulaki ye-shaft lube umgogodla we-groove omise okuka-“V”, futhi ushintshe uhlobo lwepulaki ye-shaft ye-valve enezihlalo ezimbili ibe uhlobo lomkhono;

Shintsha umkhono wefasitela ube umkhono onezimbobo ezincane, njll.

Isibonelo, i-valve enezihlalo ezimbili ye-DN25 esitshalweni sikamanyolo we-nitrogen ivamise ukudlidliza futhi yephule lapho kuxhunywa khona isiqu se-valve kanye nomongo wevalvu. Ngemva kokuqinisekisa ukuthi i-resonance, sishintshe i-valve core yesici esiwumugqa yaba i-logarithmic valve core, futhi inkinga yaxazululwa. Esinye isibonelo ivalvu yemikhono ye-DN200 esetshenziswa elabhorethri yekolishi lezindiza. Ipulaki ye-valve ibizungeza ngamandla futhi ayikwazanga ukusetshenziswa. Ngemva kokushintsha umkhono ngefasitela emkhonweni onembobo encane, ukujikeleza kwanyamalala ngokushesha.

6. Shintsha uhlobo lwe-valve elawulayo ukuze kuqedwe i-resonance

Amafrikhwensi emvelo ama-valve alawulayo anezinhlobo ezahlukene zesakhiwo ahlukile ngokwemvelo. Ukushintsha uhlobo lwe-valve elawulayo kuyindlela ephumelela kakhulu yokuqeda i-resonance.

I-resonance ye-valve inzima kakhulu lapho isetshenziswa - idlidliza kakhulu (ezimweni ezimbi kakhulu, i-valve ingabhujiswa), ijikeleza ngamandla (ngisho nesiqu se-valve siyanyakaziswa noma sisontekile), futhi ikhiqiza umsindo onamandla (okufika kuma-decibel angu-100). ). Vele ubeke i-valve nge-valve enomehluko omkhulu wesakhiwo, futhi umphumela uzoba ngokushesha, futhi i-resonance eqinile izonyamalala ngokuyisimangaliso.

Isibonelo, i-valve yemikhono ye-DN200 ikhethelwa iphrojekthi entsha yokwandisa yemboni ye-vinylon. Izimo ezintathu ezingenhla zikhona. Ipayipi le-DN300 liyagxuma, ipulaki ye-valve iyazungeza, umsindo ungaphezu kwama-decibel ayi-100, kanti ukuvuleka kwe-resonance kungu-20 kuya ku-70%. Cabangela ukuvuleka kwe-resonance. Iziqu zikhulu. Ngemva kokusebenzisa i-valve enezihlalo ezimbili, i-resonance yanyamalala futhi ukusebenza kwakujwayelekile.

7. Indlela yokunciphisa ukudlidliza kwe-cavitation

Ngokudlidliza kwe-cavitation okubangelwa ukuwa kwamabhamuza e-cavitation, kungokwemvelo ukuthola izindlela zokunciphisa i-cavitation.

Amandla omthelela akhiqizwa ukuqhuma kwebhamuza awenziwa endaweni eqinile, ikakhulukazi i-valve core, kodwa amuncwa uketshezi. Amavalvu omkhono analesi sici, ngakho-ke uhlobo lwe-valve yohlobo lwepulaki ye-shaft lungashintshwa lube uhlobo lomkhono.

Thatha zonke izinyathelo zokunciphisa i-cavitation, njengokwenyuka kokumelana ne-throttling, ukwandisa ingcindezi ye-constriction orifice, ukunciphisa ukucindezela kwesiteji noma uchungechunge, njll.

8. Gwema indlela yokuhlasela yamagagasi omthombo wokudlidliza

Ukushaqeka kwegagasi okuvela emithonjeni yangaphandle yokudlidliza kubangela ukudlidliza kwe-valve, ngokusobala into okufanele igwenywe ngesikhathi sokusebenza okuvamile kwe-valve elawulayo. Uma ukudlidliza okunjalo kwenzeka, izinyathelo ezihambisanayo kufanele zithathwe.
