Excavator hydraulic pump solenoid valve proportional solenoid valve TM68301

Proportional valve, taolo ea phallo ea valve e ka aroloa ka mefuta e 'meli. E 'ngoe ke taolo ea ho fetola, e' ngoe ke taolo e tsoelang pele, li-valve tsa servo le li-valve tse ling li fapane, tahlehelo ea matla a eona e kholoanyane, hobane e hloka phallo e itseng ho boloka mosebetsi oa potoloho ea oli ea pele ho sethaleng. E 'ngoe ke taolo ea switch: ekaba e butsoe ka botlalo kapa e koetsoe ka botlalo, sekhahla sa phallo e ka ba se phahameng kapa se tlase, ha ho na boemo ba mahareng, joalo ka valve e tloaelehileng ea motlakase ka valve, valafo ea motlakase e khutlisetsang morao, electro-hydraulic reversing valve. E 'ngoe ke taolo e tsoelang pele: sekepe sa valve se ka buloa ho ea ka tlhokahalo ea tekanyo leha e le efe ea ho bula, ka hona ho laola boholo ba phallo, li-valve tse joalo li na le taolo ea matsoho, tse kang li-valve tsa throttle, empa hape li laoloa ka elektronike, tse kang proportional. li-valve, li-valve tsa servo.

Taolo e ikemetseng e ka aroloa ka taolo ea nakoana le taolo e tsoelang pele. Taolo ea nakoana ke taolo ea switch. Lenaneong la taolo ea moea, ON-OFF e khutlisetsang valve e nang le lebelo le tlaase la ts'ebetso e sebelisoa ho laola ho theoha ha tsela ea khase. Itšetlehe ka valve ea ho fokotsa khatello ho lokisa khatello e hlokahalang, itšetleha ka valve ea throttle ho lokisa phallo e hlokahalang. Sistimi ena ea setso ea taolo ea moea e batla ho ba le matla a mangata a tlhahiso le lebelo la ho sisinyeha ka makhetlo a mangata, e hloka li-valve tse fokotsang khatello, li-throttle valves le li-valve tse khutlisetsang morao. Ka tsela ena, ha se feela likarolo tse hlokang ho feta, litšenyehelo li phahame, sebopeho sa tsamaiso se rarahane, 'me likarolo tse ngata li hloka ho lokisoa ka letsoho esale pele. Taolo ea proportional valve ea motlakase ke ea taolo e tsoelang pele, e khetholloang ka liphetoho tsa palo ea tlhahiso le palo e kentsoeng, 'me ho na le kamano e itseng e leka-lekaneng pakeng tsa palo ea tlhahiso le palo ea ho kenya. Taolo e leka-lekaneng e na le loop e bulehileng Phapang pakeng tsa taolo le taolo e koetsoeng.
