Ifanele 953C 963C excavator izesekeli proportional solenoid valve 130-6913

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.
 

Umgomo oyinhloko we-proportional solenoid valve ukuthi isignali yokulawula ukugeleza namandla okulawula asetshenziswa njengomthombo wamandla wekhoyili kagesi, ukuze i-electromagnetic ilawule ukuvulwa kwe-valve, ngakho ukuvulwa kwe-valve kucishe kulingane usayizi wesiginali yokulawula ukugeleza. Ngokuhambisana nokugeleza okuhlukile, indawo yokulawula ngayinye inenani elihlukile lokugeleza, elibuyiselwa kusilawuli sokugeleza, isilawuli sokugeleza singakwazi ukulungisa indawo ye-valve ngokusho kwesignali yokuphuma yesayizi efanayo nokugeleza lapha, ukuze ukufeza izidingo zokulawula ezinembile.

Umgomo wokulawula we-valve ye-solenoid elinganayo inezici ezintathu eziyinhloko: okokuqala, ukuguquguquka kwesignali kagesi kuthinta izinga lokuvula le-valve; Okwesibili ukulawula ukujikeleza kwe-valve ngokusebenzisa amandla kazibuthe kagesi; Okwesithathu ukulawula izinga lokuvula le-valve ngokusho kokujikeleza kwe-valve, bese udlulisela iluphu yesignali yempendulo kusilawuli sokugeleza ukuze kuzuzwe ukulawula ukugeleza.
Inqubo yokusebenza ye-proportional solenoid valve ingafingqwa njengezinyathelo ezine.
Okokuqala, ukunikezwa kwamandla kuhlala kuzinzile, bese isignali yokulawula ukulinganisa itholakala kumlawuli futhi idluliselwe ku-valve ye-solenoid elinganayo;
Okwesibili, isignali yokulawula ngokulinganayo iguqulwa ibe i-electromagnetic force excitation, ngaleyo ndlela ilawula ukujikeleza kwe-valve;
Okwesithathu, ngokusho kokujikeleza kwe-valve ukulawula izinga lokuvula le-valve, bese impendulo kumlawuli; Okwesine, ngokusho kwesignali yempendulo ukulungisa isiphethu se-valve, ukuze kuzuzwe ukulawula okunembile kwedigri yokuvula i-valve.
I-valve ye-solenoid elinganayo iyindlela ebalulekile yokulawula ngokunembile ukugeleza nokucindezela, okungafinyelela ukugeleza okusheshayo nokunembile nokulawulwa kwengcindezi, futhi isetshenziswa kabanzi ekulawuleni okuhlukahlukene kwesistimu ye-hydraulic. Isebenzisa ubuchwepheshe be-"position feedback" ukuze ilawule ngokunembile izinga lokuvula le-valve, ngaleyo ndlela izuze imiphumela yokulawula evelele, ikakhulukazi kuzinhlelo zokusebenza ze-hydraulic ezidinga ikhwalithi ephezulu.
