Ivalvu ye-hydraulic valve pilot esebenza ivalvu yokukhulula Ibhalansi yesilayidi valvu i-RPGC-LAN

Ukuhlukaniswa kwama-valve okugeleza

Ukuhlukanisa: i-throttle valve, i-valve yokugeleza, i-valve yokulawula isivinini

I-1) Ngenxa yokuthi umsebenzi oyinhloko we-valve ye-throttle kanye ne-valve yokulawula isivinini ohlelweni lwe-hydraulic ukulungisa ukugeleza kwesistimu noma igatsha, iqoqo libizwa ngokuthi i-valve yokugeleza.

I-2) Ngezinye izikhathi i-valve yokugeleza empeleni ibhekisela ku-valve yokulawula isivinini.

I-3) Kusukela kufomula eyisisekelo yokugeleza kwengcindezi, i-valve ye-throttle ishintsha kuphela ubukhulu bendawo yokugeleza kwe-valve port, futhi izinga lokugeleza elilawulwayo liphinde lithinteke ngokushintsha komehluko wengcindezi ngaphambi nangemva kwayo; I-valve yokulawula isivinini (ngezinye izikhathi ebizwa ngokuqondile ngokuthi i-valve yokugeleza) ithatha noma i-valve yokunciphisa ingcindezi ewuchungechunge, noma i-valve yokukhulula ehlukanisayo ehambisanayo, ngokulandelana eyakha i-valve elawula isivinini enezindlela ezimbili (engase imiswe ochungechungeni ngaphambi nangemuva kwe-actuator, noma ngokuhambisana phambi kwe-actuator) kanye ne-valve yokulawula isivinini sendlela ezintathu (engakwazi ukuxhunywa kuphela ochungechungeni ngaphambi kwe-actuator, futhi ingakwazi ukulawula umthwalo kuphela);

I-4) I-valve yokulawula isivinini sezindlela ezimbili ngokuvamile isetshenziselwa isimiso sokucindezela okungaguquki, ngenxa yesinxephezelo sokucindezela komthwalo, lapho ingcindezi yomthwalo ishintsha kakhulu, ukugeleza kokulawula akuthinteki; Kodwa-ke, izonxephezela ukusetshenziswa kwengcindezi ngokweqile ngendlela yokulahlekelwa kwengcindezi embobeni ye-valve. Ukugeleza ngokweqile kwesistimu nakho kudliwe ngendlela yokushisa kwamafutha.

I-5) I-valve yokulawula isivinini sezindlela ezintathu iyisistimu yokonga amandla ngoba inomsebenzi wokuzivumelanisa nomthwalo, okungukuthi, ukucindezela kokuphuma kwepompo kuyinani elithile kuphela eliphakeme kunomthwalo (3-8bar). Ngokuvamile ifakwe i-valve yokucindezela komshayeli, ngaphandle kwe-valve yokuphepha, ingafinyelela ukuvikelwa kokuphepha kwesistimu. Embonini yemishini yepulasitiki, ngokuvamile ngesisekelo se-valve yezindlela ezintathu, indlela yokulungisa ngokulinganayo ye-electro-hydraulic proportional pressure pilot valve kanye ne-valve yokugeleza ilungiselelwa ukwakha i-electro-hydraulic proportional proportional pressure flow valve composite control valve, ngokuvamile. eyaziwa ngokuthi i-pq valve, eyenza ukwakheka kube lula futhi yonge amandla.
