Ivalve ye-excavator solenoid iseti 423-4562 ivalve elinganayo ye-solenoid

Umgaqo-siseko wokusebenza kwevalvu ye-electromagnetic kunye nokufunyanwa:

Ulawulo lwevalve lokuhamba lunokwahlulwa lube ziindidi ezimbini:
Olunye lulawulo lokutshintsha: nokuba luvuleke ngokupheleleyo okanye luvalwe ngokupheleleyo, izinga lokuqukuqela linokuba likhulu okanye lincinci, akukho mbuso uphakathi, njengesiqhelo sombane we-electromagnetic ngokusebenzisa iivalvu, i-electromagnetic reversing valves, i-electro-hydraulic reversing valves.
Olunye lulawulo oluqhubekayo: i-valve port inokuvulwa ngokwesidingo salo naliphi na iqondo lokuvula, ngaloo ndlela ilawula ubungakanani bokuqukuqela, iivalvu ezinjalo zinolawulo lwezandla, olufana ne-throttle valves, kodwa zilawulwa nge-elektroniki, ezifana nokulinganisa. iivalve, iivalve zeservo.
Ke injongo yokusebenzisa ivalve elinganayo okanye ivalve ye-servo yile: ukufezekisa ulawulo lokuhamba ngolawulo lwe-elektroniki (ewe, emva kokuba utshintsho lwesakhiwo lunokufikelela kulawulo loxinzelelo, njl.njl.), kuba lulawulo lokuthomalalisa, kufuneka kubekho ukulahleka kwamandla, i-servo. i-valve kunye nezinye iivalve zihluke, ukulahlekelwa kwayo kwamandla kukhulu, kuba idinga ukuhamba okuthile ukuze kugcinwe umsebenzi wesiphaluka sokulawula i-oyile yangaphambili.

Umgaqo osebenzayo wevalve ye-solenoid elinganayo

Isekelwe kumgaqo we-solenoid on-off valve: xa amandla ecinyiwe, intwasahlobo icinezela i-core ngqo kwisihlalo, ibangela ukuba i-valve ivale. ikhoyili
Xa umbane usetyenziswa, amandla ombane avelisiweyo ayoyisa amandla asentwasahlobo kwaye aphakamise undoqo, ngaloo ndlela avule ivalve. Ivalve ye-solenoid elinganayo yenza utshintsho oluthile kwisakhiwo sevalve ye-solenoid: yenza ibhalansi phakathi kwamandla asentwasahlobo kunye namandla ombane we-electromagnetic phantsi kwayo nayiphi na i-coil current. Ubungakanani bekhoyili yangoku okanye ubungakanani bamandla e-electromagnetic buya kuchaphazela i-plunger stroke kunye nokuvulwa kwevalvu, kunye nokuvulwa kwevalve (ukuhamba) kunye nekhoyili yangoku (uphawu lolawulo) lubudlelwane obufanelekileyo bomgca.
Ivalve ye-solenoid esebenza ngokuthe ngqo ihamba phantsi kwesitulo. I-medium ingena isuka phantsi kwesihlalo, kwaye isalathiso samandla siyafana namandla ombane we-electromagnetic, kunye nesichasi samandla asentwasahlobo. Ngoko ke, kuyimfuneko ukuseta amaxabiso aphezulu kunye amancinci ahambelana noluhlu lokusebenza (coil current) kwimeko yokusebenza. Ivalve yeproportional solenoid ye-Drey fluid ivaliwe (NC, uhlobo oluqhelekileyo oluvaliweyo) xa umbane ucinyiwe.
