1. Ukwandisa ukuqina

Kwi-oscillations kunye nokunyakaza okuncinci, ukuqina kunokwandiswa ukuphelisa okanye ukuwenza buthathaka. Ngokomzekelo, ukusebenzisa intwasahlobo enobunzima obukhulu okanye ukusebenzisa i-actuator yepiston inokwenzeka.

2. Ukwandisa ukumanzisa

Ukwandisa ukumanzi kuthetha ukwandisa ukukhuhlane ngokuchasene nokungcangcazela. Ngokomzekelo, iplagi yevalve yevalve yomkhono inokutywinwa ngendandatho ethi "O", okanye i-graphite filler ene-friction enkulu, enokuthi idlale indima ethile ekupheliseni okanye ekunciphiseni ukungcangcazela okuncinci.

3. Yandisa ubungakanani besikhokelo kwaye unciphise umsantsa ofanelekileyo

Ubungakanani besikhokelo seiivalve zeplagi yeshaftngokuqhelekileyo incinci, kwaye ukucaca okuhambelana nazo zonke iivalvu kukhulu ngokubanzi, ukusuka kwi-0.4 ukuya kwi-1 mm, eluncedo ekuveliseni ukungcangcazela komatshini. Ngoko ke, xa ukunyakaza okuncinci kumatshini kwenzeka, ukungcangcazela kunokwenziwa buthathaka ngokunyusa ubungakanani besikhokelo kunye nokunciphisa isithuba esifanelekileyo.

4. Guqula imilo ye-throttle ukuphelisa i-resonance

Ngenxa yokuba okubizwa ngokuba ngumthombo wokungcangcazela kweivelufa elawulayokwenzeka kwizibuko le-throttle apho ukuhamba kwesantya esiphezulu kunye noxinzelelo lutshintsha ngokukhawuleza, ukutshintsha imilo yelungu le-throttle kunokutshintsha ukuphindaphinda komthombo we-vibration, ekulula ukuyisombulula xa i-resonance ingenamandla.

Indlela ethile kukuguqula indawo egobileyo ye-valve core nge-0.5 ~ 1.0mm ngaphakathi kwendawo yokuvula i-vibration. Umzekelo, aivalve yokulawula uxinzelelo olusebenza ngokuzimeleyoifakwe kufutshane nommandla wosapho lomzi-mveliso. Isandi sompempe esibangelwa kukuvakala sichaphazela bonke abasebenzi. Emva kokuba i-valve core surface ijikwe nge-0.5mm, isandi sokubethelwa kwempempe siyanyamalala.

5. Faka indawo ye-throttling inxalenye yokuphelisa i-resonance

Iindlela zezi:

Guqula iimpawu zokuhamba, i-logarithmic ukuya kumgca, i-linear ukuya kwi-logarithmic;

Buyisela ifom engundoqo yevalve. Umzekelo, tshintsha uhlobo lweplagi ye-shaft kwi-"V"-shaped groove valve core, kwaye utshintshe uhlobo lweplagi ye-shaft yevalve yesitulo esiphindwe kabini ukuya kuhlobo lomkhono;

Guqula umkhono wefestile kwi-sleeve enemingxuma emincinci, njl.

Umzekelo, ivalve ye-DN25 ehlala kabini kwisityalo se-nitrogen yesichumiso ihlala ingcangcazela kwaye yaphuka ekudibaneni kwesiqu sevalve kunye nombindi wevalvu. Emva kokuba siqinisekisile ukuba i-resonance, satshintsha i-valve ye-valve core kwi-logarithmic valve core, kwaye ingxaki yasonjululwa. Omnye umzekelo sisivalo se-DN200 esisetyenziswa kwilabhoratri yekholeji yokubhabha. Iplagi yevalvu ijikelezwe ngamandla kwaye ayinakusetyenziswa. Emva kokutshintsha umkhono ngefestile kwi-sleeve kunye nomngxuma omncinci, ukujikeleza ngokukhawuleza kwanyamalala.

6. Guqula uhlobo lwevalve yokulawula ukuphelisa i-resonance

Iifrikhwensi zendalo zokulawula iivalvu ezineendlela ezahlukeneyo zesakhiwo zahluke ngokwendalo. Ukutshintsha uhlobo lwevalve elawulayo yeyona ndlela isebenzayo yokuphelisa i-resonance.

I-resonance yevalve inzima kakhulu ngexesha lokusetyenziswa - ishukuma ngamandla (kwiimeko ezinzima, ivalve inokutshatyalaliswa), ijikeleza ngamandla (nokuba i-valve stem ishukunyiswa okanye ijijekile), kwaye ivelisa ingxolo enamandla (ukuya kuthi ga kwi-decibels ezingaphezu kwe-100. ). Mane utshintshe i-valve nge-valve enomahluko omkhulu wesakhiwo, kwaye umphumo uya kuba ngokukhawuleza, kwaye i-resonance eyomeleleyo iya kunyamalala ngokumangalisayo.

Ngokomzekelo, i-valve ye-sleeve ye-DN200 ikhethiwe kwiprojekthi entsha yokwandisa i-vinylon factory. Ezi ziganeko zintathu zingasentla zikhona. Umbhobho we-DN300 utsiba, iplagi yevalve ijikeleza, ingxolo ingaphezulu kwe-100 decibels, kwaye ukuvulwa kwe-resonance yi-20 ukuya kwi-70%. Cinga ngokuvula isandi. Isidanga sikhulu. Emva kokusebenzisa i-valve enezihlalo ezimbini, i-resonance yanyamalala kwaye umsebenzi wawuqhelekile.

7. Indlela yokunciphisa i-cavitation vibration

Kwi-vibration ye-cavitation ebangelwa ukuwa kwe-bubbles cavitation, kungokwemvelo ukufumana iindlela zokunciphisa i-cavitation.

Amandla empembelelo aveliswa kukugqabhuka kweqamza awenziwa kumphezulu oqinileyo, ngakumbi undoqo wevalvu, kodwa afunxwa lulwelo. Iivalve zemikhono zineluphawu, ngoko ke undoqo wevalve yohlobo lweplagi yeshaft unokutshintshwa ube luhlobo lomkhono.

Thatha onke amanyathelo okunciphisa i-cavitation, njengokwandisa ukunyanzeliswa kwe-throttling, ukwandisa uxinzelelo lwe-constriction orifice, isiteji okanye uchungechunge lokunciphisa uxinzelelo, njl.

8. Kuphephe indlela yohlaselo lwamaza omthombo wokungcangcazela

Ukothuso lwamaza oluvela kwimithombo yangaphandle yokungcangcazela kubangela ukungcangcazela kwevalve, nto leyo ngokucacileyo ekufuneka igwenywe ngexesha lokusebenza okuqhelekileyo kwevalve elawulayo. Ukuba ukungcangcazela okunjalo kwenzeka, amanyathelo ahambelanayo kufuneka athathwe.
