1. Yandisa ukuqina

Kwi-oscillations kunye ne-vibrations encinci, ukuqina kunokwandiswa ukuze kususwe okanye kubuthathaka. Umzekelo, ukusebenzisa i-spring enokuqina okukhulu okanye ukusebenzisa i-piston actuator kunokwenzeka.

2. Ukwandisa ukufuma

Ukwandisa ukuxinana kuthetha ukwandisa ukungqubana ngokuchasene nokungcangcazela. Umzekelo, iplagi yevalvu yevalvu yesingxobo inokutywinwa ngendandatho ethi “O”, okanye i-graphite filler enongqubano olukhulu, enokudlala indima ethile ekususeni okanye ekunciphiseni ukungcangcazela okuncinci.

3. Yandisa ubungakanani besikhokelo kwaye unciphise umsantsa wokulingana

Ubungakanani besikhokeloiivalvu zeplagi yeshaftngokubanzi incinci, kwaye indawo ehambelanayo yazo zonke iivalvu ngokubanzi inkulu, ukusuka kwi-0.4 ukuya kwi-1 mm, nto leyo eluncedo ekuveliseni ukungcangcazela koomatshini. Ke ngoko, xa kuvela ukungcangcazela okuncinci koomatshini, ukungcangcazela kunokwenziwa buthathaka ngokwandisa ubungakanani besikhokelo kunye nokunciphisa umsantsa wokulingana.

4. Tshintsha imo ye-throttle ukuze ucime i-resonance

Ngenxa yokuba umthombo wokungcangcazela obizwa ngokuba yi-vibrationivalvu yokulawulakwenzeka kwi-throttle port apho ukuhamba ngesantya esiphezulu kunye noxinzelelo kutshintsha ngokukhawuleza, ukutshintsha imo yelungu le-throttle kunokutshintsha i-frequency yomthombo wokungcangcazela, nto leyo elula ukuyisombulula xa i-resonance ingekho ngamandla.

Indlela ethile kukuguqula umphezulu ogobileyo we-valve core nge-0.5 ~ 1.0mm ngaphakathi koluhlu lokuvula ukungcangcazela. Umzekelo,ivalvu yokulawula uxinzelelo oluzisebenzelayoifakelwe kufutshane nendawo yosapho lomzi-mveliso. Isandi somlozi esibangelwa kukukhala kwesandi sichaphazela abanye abasebenzi. Emva kokuba umphezulu wevalvu ujikwe nge-0.5mm, isandi somlozi wesandi siyanyamalala.

5. Buyisela indawo eqhoboshelayo ukuze ucime ukurhawuzelelwa

Iindlela zezi:

Tshintsha iimpawu zokuhamba, i-logarithmic ibe yi-linear, i-linear ibe yi-logarithmic;

Tshintsha imo yesiseko sevalvu. Umzekelo, tshintsha uhlobo lweplagi yeshaft ibe yi-groove valve core efana no-“V”, kwaye utshintshe uhlobo lweplagi yeshaft yevalvu enezihlalo ezimbini ibe yi-sleeve;

Tshintsha umkhono wefestile ube ngumkhono onemingxuma emincinci, njl.

Umzekelo, ivalvu yezihlalo ezimbini ye-DN25 kwisityalo sesichumisi se-nitrogen yayidla ngokungcangcazela kwaye yaphuka xa kuqhagamshelwa phakathi kwesiqu sevalvu kunye nesiseko sevalvu. Emva kokuba siqinisekisile ukuba yayiyi-resonance, satshintsha isiseko sevalvu esinophawu oluthe tye saba yisiseko sevalvu ye-logarithmic, kwaye ingxaki yasonjululwa. Omnye umzekelo yivalvu yesiliva ye-DN200 esetyenziswa kwilebhu yekholeji yeenqwelo moya. Iplagi yevalvu yajikeleza ngamandla kwaye yayingenakusetyenziswa. Emva kokutshintsha i-sleeve ngefestile ibe yi-sleeve enomngxuma omncinci, ukujikeleza kwaphela ngoko nangoko.

6. Tshintsha uhlobo lwevalvu elawulayo ukuze kupheliswe ukurhawuzelelwa

Iifrikhwensi zendalo zeevalvu ezilawulayo ezineemilo ezahlukeneyo zesakhiwo zahlukile ngokwemvelo. Ukutshintsha uhlobo lwevalvu elawulayo yeyona ndlela isebenzayo yokuphelisa ngokupheleleyo isandi.

Isandi sevalvu sinzima kakhulu xa sisetyenziswa – siyangcangcazela kakhulu (kwiimeko ezinzima, ivalvu inokutshatyalaliswa), ijikeleza ngamandla (nokuba isiqu sevalvu siyangcangcazela okanye sijijekile), kwaye ivelisa ingxolo enamandla (ukuya kuthi ga kwi-100 decibels). Tshintsha nje ivalvu ngevalvu enomahluko omkhulu wolwakhiwo, kwaye isiphumo siya kuba ngoko nangoko, kwaye isandi esinamandla siya kuphela ngokungummangaliso.

Umzekelo, ivalvu yesilingi ye-DN200 ikhethiwe kwiprojekthi entsha yokwandisa yefektri ye-vinylon. Ezi zinto zintathu zingasentla zikhona. Ipayipi ye-DN300 iyatsiba, iplagi yevalvu iyajikeleza, ingxolo ingaphezulu kwe-100 decibels, kwaye ukuvulwa kwe-resonance yi-20 ukuya kwi-70%. Cinga ngokuvulwa kwe-resonance. Iqondo likhulu. Emva kokusebenzisa ivalvu enezihlalo ezimbini, i-resonance yaphela kwaye umsebenzi wawuqhelekile.

7. Indlela yokunciphisa ukungcangcazela kwe-cavitation

Ngenxa yokungcangcazela kwe-cavitation okubangelwa kukudilika kwee-cavitation bubbles, kuyinto eqhelekileyo ukufumana iindlela zokunciphisa i-cavitation.

Amandla empembelelo adalwa kukuqhuma kwebhamuza awasebenzi kumphezulu oqinileyo, ingakumbi i-valve core, kodwa afunxwa lulwelo. Iivalve zemikhono zinale mpawu, ngoko ke i-valve type plug core ingatshintshwa ibe yi-sleeve type.

Thatha onke amanyathelo okunciphisa ukuxinana kwesisu, njengokunyusa ukumelana nokuxinana kwesisu, ukwandisa uxinzelelo lwe-orifice yokuxinana, ukunciphisa uxinzelelo olucwangcisiweyo okanye olulandelelanayo, njl.

8. Kuphephe indlela yokuhlasela amaza omthombo wokungcangcazela

Ukothuka kwamaza okuvela kwimithombo yokungcangcazela yangaphandle kubangela ukungcangcazela kwevalvu, nto leyo ngokucacileyo ekufuneka ithintelwe ngexesha lokusebenza kwevalvu elawulayo. Ukuba ukungcangcazela okunjalo kwenzeka, kufuneka kuthathwe amanyathelo afanelekileyo.
