393000M024 Excavator hydraulic pump solenoid valve proportional solenoid valve 3768317

Umahluko phakathi kwevalve yombane elinganayo kunye nevalve ye-solenoid

Ulawulo lwevalve lokuhamba lunokwahlulwa lube ziindidi ezimbini:
 

Olunye lulawulo lokutshintsha: nokuba luvuleke ngokupheleleyo okanye luvalwe ngokupheleleyo, umlinganiselo wokuhamba ungowona uphezulu okanye ubuncinci, akukho mbuso uphakathi, njengombane oqhelekileyo we-electromagnetic ngokusebenzisa ivalve, ivalve yokubuyisela umbane ye-electromagnetic, ivalve ye-electro-hydraulic reversing valve. 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 ye-Electromagnetic (ivalve ye-Electromagnetic) kusetyenziso lwe-electromagnetic

Umgaqo osebenzayo wevalve ye-solenoid elinganayo
   

Ivalve ye-electro-hydraulic proportional valve yi-proportional electromagnet igalelo lamandla ombane kwivalve ukuvelisa isenzo esihambelanayo, ukwenzela ukuba ivalve esebenzayo i-spool displacement, i-valve port size sitshintshe kwaye igqibezele uxinzelelo kunye nemveliso ye-flow output ngokulingana nombane wegalelo. Ukufuduswa kwe-spool nako kunokondliwa ngoomatshini, ngokwenziwa ngamanzi okanye ngombane. Ivalve ye-electro-hydraulic proportional valve ineefom ezahlukeneyo, kulula ukuyisebenzisa umbane kunye nolawulo lwekhompyuter kwiinkqubo ezahlukeneyo ze-electro-hydraulic, ukuchaneka kolawulo oluphezulu, ukufakwa okuguquguqukayo kunye nokusetyenziswa, kunye nekhono elinamandla lokuchasana nongcoliseko, kunye nezinye iingenelo, intsimi yesicelo iyanda. . Kwiminyaka yakutshanje, uphuhliso kunye nokuveliswa kweeplagi-in iivalvu ezilinganayo kunye ne-proportional multiway valves ziqwalasela ngokupheleleyo iimpawu zoomatshini bokwakha, kunye nolawulo lokulinga, ukuva umthwalo kunye nemisebenzi yembuyekezo yoxinzelelo. Kubaluleke kakhulu ukuphucula umgangatho wobugcisa ngokubanzi koomatshini behydraulic abahambahambayo.
