I-Hydraulic pump proportional solenoid valve 114-0616 izinsiza zemishini yobunjiniyela be-excavator

I-valve ye-solenoid ye-Proportional iyi-valve ekhethekile yokulawula i-solenoid, isimiso sayo sokulawula ukulawula ukuvulwa kwe-valve ngokusebenzisa isignali yomyalo wokufakwa kwangaphandle, ukuze ukugeleza kokulawula nokucindezela kuhlale kugcina isilinganiso esifanayo nesignali yomyalo. Isebenzisa ubuchwepheshe be-"position feedback", obungakwazi ukulungisa ngokunembile indawo ye-valve ngokusho kwesignali yokulawula ukugeleza, ukuze kuzuzwe izidingo zokulawula ezinembile, ngakho-ke isetshenziswa kabanzi ekulawuleni okunembile kwesistimu ye-hydraulic.

Isimiso esiyisisekelo sokulawula i-electro-hydraulic proportional valve control sisekelwe kumgomo we-solenoid switch valve: Uma amandla ecishiwe, isiphethu sicindezela umongo ngokuqondile esihlalweni, okwenza i-valve ivaleke. Lapho ikhoyili inikwa amandla, amandla kazibuthe kagesi akhiqizwayo anqoba amandla asentwasahlobo futhi aphakamise umongo, ngaleyo ndlela avule ivalvu. I-proportional solenoid valve yenza izinguquko ezithile esakhiweni se-solenoid valve: yenza ibhalansi phakathi kwamandla asentwasahlobo namandla kazibuthe kagesi ngaphansi kwanoma iyiphi ikhoyili yamanje. Ubukhulu bekhoyili yamanje noma usayizi wamandla kazibuthe kagesi buzothinta ukushaywa kwe-plunger nokuvuleka kwevalvu, futhi ukuvuleka kwevalvu (ukugeleza) kanye nekhoyili yamanje (isignali yokulawula) kuwubudlelwane obuhle bomugqa. Direct acting proportional valve solenoid ageleza ngaphansi kwesihlalo. I-medium igeleza isuka ngaphansi kwesihlalo, futhi isiqondiso samandla siyafana namandla kazibuthe kagesi, futhi okuphambene namandla asentwasahlobo. Ngakho-ke, kuyadingeka ukusetha amanani okugeleza amancane e-Zda kanye no-Z ahambisana nebanga lokusebenza (ikhoyili yamanje) esimweni sokusebenza. I-proportional solenoid valve ye-Drey fluid ivaliwe lapho amandla ecishiwe. Isimiso esiyisisekelo se-electro-hydraulic proportional valve control Italy I-ATOS solenoid valve isetshenziselwa ukulawula izingxenye eziyisisekelo ezizenzakalelayo zoketshezi, okungeye-actuator; Futhi akugcini ku-hydraulic, pneumatic. Ivalvu ye-ATOS solenoid iqukethe ikhoyili ye-solenoid kanye nengqikithi kazibuthe kanye nomzimba we-valve oqukethe imbobo eyodwa noma ngaphezulu. Lapho ikhoyili ivuliwe noma ivaliwe, ukunyakaza kwengqikithi kazibuthe kuzobangela ukuthi uketshezi ludlule noma lunqanyulwe ukuze kuzuzwe injongo yokuguqula indlela uketshezi oluya ngaso. Izingxenye ze-electromagnetic ze-ATOS solenoid valve zenziwe ngensimbi engaguquki, umgogodla wensimbi onyakazayo, ikhoyili yomkhono womhlahlandlela nezinye izingxenye; Ingxenye yomzimba wevalvu yakhiwe umgogodla wevalvu, umkhono wevalvu, isiphethu, isihlalo, njll. Izingxenye zikagesi zigxunyekwe ngqo emzimbeni wevalvu ukuze kube nephakheji elula, ehlangene. Ekukhiqizeni ama-valve e-solenoid avame ukusetshenziswa amabili, amabili amathathu, amabili amane, amabili amahlanu, amathathu amahlanu, njll.
