Izesekeli ze-Loader excavator 201-0950 umhlangano we-valve ye-solenoid

Isimiso sokusebenza kwe-electromagnetic proportional valve kanye nokutholwa:

Ukulawulwa kwe-valve kokugeleza kungahlukaniswa ngezinhlobo ezimbili:
Eyodwa ukulawulwa kokushintsha: kungaba kuvuleke ngokuphelele noma kuvalwe ngokugcwele, izinga lokugeleza likhulu noma lincane, asikho isimo esimaphakathi, esifana ne-electromagnetic evamile ngamavalvu, ama-electromagnetic reverse valves, ama-electro-hydraulic reversing valves.
Okunye ukulawulwa okuqhubekayo: imbobo ye-valve ingavulwa ngokwesidingo sanoma yiliphi izinga lokuvula, ngaleyo ndlela ilawule ubukhulu bokugeleza, ama-valve anjalo anokulawula okubhaliwe, njengama-throttle valve, kodwa futhi alawulwa nge-elekthronikhi, njenge-proportional. ama-valve, ama-servo valves.
Ngakho-ke inhloso yokusebenzisa i-valve ye-proportional noma i-valve ye-servo iwukuthi: ukufeza ukulawulwa kokugeleza ngokulawulwa kwe-elekthronikhi (yebo, ngemuva kwezinguquko zesakhiwo nakho kungafinyelela ukulawulwa kwengcindezi, njll.), njengoba kungukulawula okudonsayo, kufanele kube nokulahlekelwa kwamandla, i-servo. i-valve namanye ama-valve ahlukile, ukulahlekelwa kwawo kwamandla kukhulu, ngoba kudinga ukugeleza okuthile ukuze kugcinwe umsebenzi wesifunda samafutha okulawula isigaba sangaphambi kwesiteji.

I-valve eyinhloko ye-valve ye-servo ngokuvamile iyafana ne-valve ehlehlayo iyisakhiwo se-valve yesilayidi, kodwa ukuhlehliswa kwe-valve core akuqhutshwa nguzibuthe kagesi, kodwa ukukhishwa kwe-hydraulic pressure ye-valve yangaphambi kwesiteji, ifana kakhulu ne-electro-hydraulic reversing valve, kodwa i-valve yangaphambi kwesiteji ye-electro-hydraulic reversing valve iyi-solenoid ehlehla i-valve, kanti i-valve yangaphambi kwesiteji ye-servo valve iyi-nozzle baffle valve noma i-jet pipe valve engcono kakhulu. izici ashukumisayo.
Okusho ukuthi, i-valve eyinhloko ye-valve ye-servo ilawulwa ukucindezela okukhiphayo kwe-valve yangaphambi kwesiteji, futhi ingcindezi ye-valve yangaphambi kwesiteji ivela ku-inlet p ye-valve ye-servo, uma ingcindezi ye-p. imbobo ayanele, i-valve yangaphambi kwesiteji ayikwazi ukukhipha ingcindezi eyanele ukukhuthaza isenzo esikhulu se-spool.
