Excavator izincedisi 225-0300 ratio solenoid valve ukwakha oomatshini izincedisi

 Ukusetyenziswa kwevalvu elinganayo ye-electro-hydraulic kumatshini wokwakha idayagramu ye-hydraulic system yohlobo oluthile lwekhreyini yelori, kuphela iindawo ezifanelekileyo zevalvu yokulinganisa ye-electro-hydraulic ezotyiweyo kumzobo.

Umatshini usebenzisa iinqununu ze-3 ze-TECNORD TDV, i-4/3 LM, i-LS / i-PC yohlobo lwe-valve yeendlela ezininzi, i-oyile yokubona umgca we-oyile ye-3 i-spindle valves iya kukhethwa kuxinzelelo oluphezulu lwe-3 imithwalo yomsebenzi kwi-port elawulwa kude yoncedo. ivelufa, hlengahlengisa uxinzelelo lwevalve yoncedo, ukuze uxinzelelo oluphumayo lwempompo ye-hydraulic ihlangabezane neemfuno zomthwalo wenkqubo inokufezekisa ukonga okuthile kwamandla.

I-oyile yembuyekezo yoxinzelelo lwesekethe yenza ukuhamba kwevalve nganye ehambelana nokuvulwa kwevalve, kwaye ayinanto yakwenza nomthwalo, kwaye umthwalo othwalwa yipleyiti yevalve awunanto yakwenza nayo, ukuze isantya somthwalo singakwazi. ilawulwe ngentando phantsi kwawo nawuphi na umthwalo.

Umzekelo wolawulo lwe-manuwali kunye ne-electro-hydraulic proportional pilot yefosholo yebulldozer.
Xa i-valve ye-solenoid eneendlela ezimbini ingenawo amandla, uxinzelelo lomqhubi ludityaniswe nevalve yomqhubi we-decompression manual, kwaye i-valve ye-shuttle ikhetha uxinzelelo oluvela kwi-valve ye-pilot ye-manual ukulawula i-valve yokutshintsha i-hydraulic direction: xa ezimbini- Indlela ye-valve ye-solenoid eneendlela ezintathu inamandla, i-oyile yokulawula umqhubi wenqwelo-moya ikhokelela kwivalve yendlela-ntathu yokulinganisa i-decompression pilot, kunye nevalve ye-shuttle ilawula i-valve yokutshintsha i-hydraulic direction.
