Izincedisi zomlayishi we-excavator 201-0950 indibano yevalve ye-solenoid

Umgaqo 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.

Ivalve engundoqo yevalve ye-servo iyafana ngokubanzi nevalve ebuyela umva sisakhiwo sevalve yesilayidi, kodwa ukubuyiswa kondoqo wevalve akuqhutywa nguzibuthe we-electromagnetic, kodwa kukukhutshwa koxinzelelo lwehydraulic yevalve yesigaba sangaphambili, ifana ngakumbi nevalve yokubuyisela umva ye-electro-hydraulic, kodwa ivalve ye-electro-hydraulic reversing valve yivalve yokubuyisela umva ye-solenoid, kunye nevalve yaphambi kwenqanaba levalve ye-servo yivalve yombhobho okanye ivelufa yombhobho wejethi ebhetele. iimpawu eziguqukayo.
Oko kukuthi, i-valve ephambili yevalve ye-servo ilawulwa ngoxinzelelo oluphumayo lwevalve yangaphambili, kwaye uxinzelelo lwevalve yangaphambili luvela kwi-inlet p yevalve ye-servo, ukuba uxinzelelo lwe-p. izibuko ayonelanga, ivalve yangaphambili ayinakukhupha uxinzelelo olwaneleyo ukukhuthaza isenzo esiphambili se-spool.
