Ingcindezi yomshayeli wendiza iyithinta kanjani i-valve yokulinganisa?
2024-03-14Isilinganiso somshayeli we-valve ephikisanayo isilinganiso sendawo yokushayela kanye nendawo echichimayo, okusho ukuthi leli nani liphinde lilingane: lapho isiphethu se-valve esiphikisayo sisethelwa inani elilinganiselwe, ingcindezi edingekayo ukuze uyivule uma kukhona. awekho amafutha okushayela kanye namafutha okushayela ewodwa avula isilinganiso sokucindezela.
Uma ungekho uwoyela ocindezelayo embobeni kawoyela wokushayela, ukucindezela kokuvula okulinganiselwe yinani lokusetha intwasahlobo. Uma kungekho ukunikezwa kwamafutha omshayeli, i-valve yebhalansi ivulwa ngumthwalo, futhi ukwehla kwengcindezi kuzokwanda ngokuphawulekayo njengoba izinga lokugeleza landa (lokhu kusetshenziselwa ukulinganisa umthwalo). Uma ithonya lokucindezela kwe-outlet lingacatshangwa, ingcindezi yomshayeli = (isetha inani - umthwalo) / isilinganiso sendawo. Uma umshayeli wangaphakathi esetshenziswa, ingcindezi yokuvula ingasethwa ngokulungisa i-valve bolt yokusiza.
ifomula ethize
Ingcindezi yokuvula = (ingcindezi yokusetha - ingcindezi ephezulu yomthwalo) / isilinganiso somshayeli we-valve
Ku-valve yebhalansi, uma isilinganiso somhlahlandlela wayo wengcindezi ingu-3:1, kunobudlelwano obulinganayo obungu-3:1 phakathi kukawoyela wokushayela kanye nendawo yokucindezela ehambisana nomongo we-valve yokuvula inlet kawoyela, ngakho-ke ingcindezi yokulawula edingekayo ukuze uvule umgogodla we-valve. kufanele kube ngaphansi, kanye nokulawula Isilinganiso sokucindezela ekucindezelweni lapho i-oil inlet ivula i-spool cishe i-1: 3.
Isilinganiso Esiholayo
3:1 (okujwayelekile) Ifanele izimo ezinoshintsho olukhulu lomthwalo kanye nokuzinza kwemithwalo yemishini yobunjiniyela.
I-8:1 ifanele izimo lapho imfuneko yomthwalo ihlala ingashintshi.
Izimo ezihlukene zokusebenza nendawo zidinga ukukhetha okuhlukile kwesilinganiso sokucindezela. Uma umthwalo ulula futhi ukuphazamiseka kwangaphandle kukuncane, isilinganiso esikhulu sokulawula i-hydraulic ngokuvamile sikhethwa, esinganciphisa inani lokucindezela komshayeli futhi konge amandla. Ezimeni ezinokuphazamiseka okukhulu komthwalo nokudlidliza okulula, isilinganiso sokucindezela esincane ngokuvamile siyakhethwa ukuze kuqinisekiswe ukuthi ukushintshashintsha kwengcindezi yomshayeli ngeke kubangele ukudlidliza okuvamilei-valve yokulinganisaumnyombo.
Izinto okufanele uziqaphele lapho ukhetha i-valve yokulinganisa:
1. Izinga lokugeleza lingaba phezulu kancane kunezinga lokugeleza elilinganiselwe;
2. Sebenzisa i-valve enezinga eliphansi lomshayeli ngangokunokwenzeka, elizinzile;
3. I-valve yebhalansi isetshenziselwa ukulawula ukucindezela, hhayi isivinini;
4. Zonke izingcindezi ezibekiwe zivula izingcindezi;
5. Ngeke isetshenziswe njenge-valve yokusiza;
6. Hlala eduze ne-actuator ngangokunokwenzeka ukuze uvimbele ipayipi ukuthi lingaqhumi.
