Indlela yokukhetha i-valve yokulinganisa esebenza umshayeli efanelekile
2024-03-26Kusistimu ye-hydraulic, i-valve yebhalansi ingakwazi ukulawula ukuvikela ibhalansi yesilinda sikawoyela, futhi ingadlala indima ekuvikelweni kokuvuza uma kwenzeka kuqhuma ipayipi likawoyela.
Umsebenzi we-valve yebhalansi awuthintwa ukucindezela emuva. Lapho ingcindezi yembobo ye-valve ikhuphuka, ingagcina nokuvuleka okuzinzile kwe-valve core.
Ngokuvamile ingadlala indima yokuvikela ukuchichima kusekethe. Ngokuvamile kusetshenziselwa ukulawula amasistimu alinganayo.
Kungcono ukufaka i-valve yebhalansi eduze kwe-cylinder ukuze ukwandise umphumela wayo.
I-valve yokulinganisa eyodwa ingalawula imithwalo yokunyakaza eqondile, njengamapulatifomu okuphakamisa ukuphakama, ama-cranes, njll.
I-balancer ekabili ilawula imithwalo ephindaphindayo nezungezayo njengamasondo amasondo noma amasilinda amaphakathi.
1. Isilinganiso esiholayo simi kanje:
①3:1 (okujwayelekile) Ifanele izimo ezinoshintsho olukhulu lomthwalo nokuzinza kwemithwalo yemishini yobunjiniyela.
I-②8:1 ifanele izimo lapho umthwalo kudingeka ukuthi ungashintshi.
2. Isimiso sokusebenza
Ingxenye ye-valve yendlela eyodwa ivumela uwoyela wokucindezela ukuthi ugeleze ngokukhululekile kusilinda kuyilapho uvimbela ukugeleza kwamafutha okubuyela emuva. Ingxenye yomshayeli ingalawula ukunyakaza ngemva kokusungula ingcindezi yomshayeli. Ingxenye yomshayeli ivame ukusetha ifomu elivulekile elivamile, futhi ingcindezi isethelwe izikhathi ezingu-1.3 inani lomthwalo, kodwa ukuvulwa kwe-valve kunqunywa isilinganiso somshayeli.
Ngokulawulwa kokulayisha okuthuthukisiwe nezinhlelo zokusebenza zamandla ahlukene, izilinganiso zomshayeli ezihlukile kufanele zikhethwe.
Ukuqinisekiswa kwenani lokucindezela kokuvula kwe-valve kanye nenani lokucindezela lokunyakaza kwe-cylinder kutholakala ngokusho kwefomula elandelayo: isilinganiso somshayeli = [(ukusetha ingcindezi yokukhulula) - (ukucindezela komthwalo)] / ukucindezela komshayeli.
I-hydraulic control ratio ye-balance valve ibizwa nangokuthi i-pilot pressure ratio, ngokuvamile ebizwa ngokuthi isilinganiso somshayeli ngesiNgisi. Kubhekiselwa esilinganisweni senani lokucindezela kokuvula emuva kwe-valve yebhalansi lapho uwoyela wokushayela engu-0 ngemva kokuba isiphethu se-valve yebhalansi sisethelwe inani elithile eligxilile kanye nenani lokucindezela komshayeli lapho i-valve ebhalansi enamafutha omshayeli ivuleka ibheke emuva. .
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.
Ezimweni lapho ukuphazamiseka komthwalo kukhulu futhi ukudlidliza kulula, isilinganiso sokucindezela esincane ngokuvamile siyakhethwa ukuze kuqinisekiswe ukuthi ukushintshashintsha kwengcindezi yomshayeli ngeke kubangele ukudlidliza okuvamile kwe-valve core.
3. Isifinyezo
Isilinganiso somshayeli siyipharamitha ebalulekile ekusebenzeni kwesistimu ye-hydraulic. Kungathinta amandla okukhiya namandla okuvula, ukusebenza kokukhiya kanye nempilo yesevisi ye-valve yebhalansi. Ngakho-ke, ngesikhathi sokukhethwa kanye nokusetshenziswa kwe-valve yokulinganisa, kuyadingeka ukucabangela ngokugcwele umthelela we-valve yokulinganisa.isilinganiso somshayeliekusebenzeni kwayo futhi ukhethe isilinganiso esifanele somshayeli we-valve yokulinganisa ukuze uqinisekise ukusebenza okuthembekile kwe-valve yokulinganisa.
