Indlela yokukhetha ivalve efanelekileyo yokulinganisa eqhutywa ngumqhubi wenqwelomoya
2024-03-26Kwinkqubo ye-hydraulic, ivalve yebhalansi inokuqonda ulawulo lokhuseleko lwe-oyile, kwaye inokudlala indima ekukhuseleni ukuvuza kwimeko yokuqhuma kombhobho weoyile.
Umsebenzi we-valve yokulinganisela awuchaphazeli uxinzelelo lwangasemva. Xa uxinzelelo lwe-valve port lukhula, lunokugcina ukuvulwa okuzinzileyo kwe-core valve.
Ngokuqhelekileyo inokudlala indima yokukhusela ukuphuphuma kwisekethe. Idla ngokusetyenziswa ukulawula iinkqubo zolungelelwaniso.
Kungcono ukufaka i-valve yebhalansi kufuphi ne-cylinder ukwandisa umphumo wayo.
I-valve yokulinganisa enye inokulawula imithwalo yentshukumo yomgca, njengamaqonga okunyusa aphakamileyo, iikrane, njl.
I-balancer ephindwe kabini ilawula ukuphindaphinda kunye nokujikeleza kwemithwalo efana neenjini zamavili okanye iisilinda ezingaphakathi.
1. Umlinganiselo okhokelayo umi ngolu hlobo lulandelayo:
①3: 1 (umgangatho) Ilungele iimeko ezinotshintsho olukhulu lomthwalo kunye nokuzinza komatshini wobunjineli.
②8: I-1 ifanelekile kwiimeko apho umthwalo ufuneka ukuba uhlale ungatshintshi.
2. Umgaqo wokusebenza
Ingxenye yevalve yendlela enye ivumela i-oyile yoxinzelelo ukuba ihambe ngokukhululekileyo kwi-cylinder ngelixa ikhusela ukujikeleza kweoli. Inxalenye yepilot inokulawula intshukumo emva kokumisela uxinzelelo lomqhubi. Inxalenye yomqhubi ivame ukusetwa kwifom evulekileyo ngokuqhelekileyo, kwaye uxinzelelo lubekwe kumaxesha angama-1.3 ixabiso lomthwalo, kodwa ukuvulwa kwe-valve kunqunywe ngumlinganiselo womqhubi.
Kulawulo lomthwalo oluphuculweyo kunye nosetyenziso lwamandla olwahlukileyo, umlinganiselo wokulinga owahlukileyo kufuneka ukhethwe.
Ukuqinisekiswa kwexabiso loxinzelelo lokuvula i-valve kunye nexabiso loxinzelelo lwe-cylinder movement lifunyenwe ngokwefomula elandelayo: i-pilot ratio = [(i-relief setting setting) - (uxinzelelo lomthwalo)] / uxinzelelo lomqhubi.
I-hydraulic control ratio yevalve yokulinganisa ikwabizwa ngokuba yi-pilot pressure ratio, ngokuqhelekileyo ibizwa ngokuba yi-pilot ratio ngesiNgesi. Ibhekisa kumyinge wexabiso loxinzelelo lokuvula umva lwevalvu yokulinganisa xa i-oyile yokulinga i-0 emva kokuba isiseko sevalve yebhalansi isetelwe kwixabiso elithile elimiselweyo kunye nexabiso loxinzelelo lomqhubi xa ivalve yebhalansi eneoli yokulinga ivula kwicala elingasemva. .
Iimeko ezahlukeneyo zokusebenza kunye neendawo ezingqongileyo zifuna ukhetho oluhlukeneyo lomlinganiselo woxinzelelo. Xa umthwalo ulula kunye nokuphazamiseka kwangaphandle kuncinci, umlinganiselo omkhulu wokulawula i-hydraulic ukhethwa ngokuqhelekileyo, onokunciphisa ixabiso loxinzelelo lomqhubi kunye nokugcina amandla.
Kwiimeko apho ukuphazamiseka komthwalo kukhulu kwaye ukungcangcazela kulula, umlinganiselo omncinci woxinzelelo ngokuqhelekileyo ukhethwa ukuqinisekisa ukuba ukuguquguquka koxinzelelo lomqhubi akuyi kubangela ukungcangcazela rhoqo kwe-valve core.
3. Isishwankathelo
Umlinganiselo we-pilot yiparameter ebalulekileyo ekusebenzeni kwe-hydraulic system. Inokuchaphazela amandla okuvala kunye nokuvula amandla, ukutshixa ukusebenza kunye nobomi benkonzo yevalve yokulinganisela. Ngoko ke, ngexesha lokukhethwa kunye nokusetyenziswa kwevalve yokulinganisa, kuyimfuneko ukuqwalasela ngokubanzi impembelelo ye-valve yokulinganisa.umlinganiselo wepilotekusebenzeni kwayo kwaye ukhethe umlinganiselo ofanelekileyo wokulinganisa wevalve yokulinganisa ukuqinisekisa ukusebenza okuthembekileyo kwevalve yokulinganisa.
