Belofo ea liphallelo PC220-6 valve ea polokeho ea Excavator 708-2L-04740

Ho na le mefuta e mengata ea li-valve tsa solenoid ho li-excavator tse nyane. Pele ho tsohle, re tlameha ho tseba molao-motheo o sebetsang oa valve ea solenoid. Valve ea solenoid ea mochini o epang e sebelisa electromagnet ho sututsa konokono ea valve ho laola tsela eo moea o hatelitsoeng ka eona, e le ho laola tsela ea switch ea pneumatic actuator. Electromagnetic directional valve ho latela litlhoko tse fapaneng e ka fihlela litsela tse peli, tse peli tse hlano joalo-joalo
Ntlha ea pele, sebopeho sa valve ea solenoid: coil, makenete, molamu oa ejector.

Molao-motheo o sebetsang oa valve ea solenoid ea moepo o monyenyane ke hore ha coil e hokahane le hona joale, e hlahisa magnetism, e hohelana ka makenete, makenete e hula molamu oa ejector, e tima matla, magnet le rod ejector. li setiloe bocha, 'me ts'ebetso ea ts'ebetso e phethiloe.

Ea bobeli, motlakase o sebelisoang ho sebelisa valve ea solenoid holim'a sekoahelo se senyenyane se arotsoe ka AC le DC.

Matla a motlakase oa AC electromagnet hangata ke 220V, e khetholloang ka matla a maholo a qalang, nako e khuts'oane ea ho khutlisa le theko e tlase. Leha ho le joalo, ha mokokotlo oa valve o sa khomarele ka ho lekaneng 'me mokokotlo oa tšepe o sa anyeloe, motlakase oa motlakase o bonolo ho chesa ka lebaka la hona joale ho feteletseng, kahoo monyetla oa ho sebetsa o fokola, ketso e na le tšusumetso,' me bophelo bo khutšoanyane. Matla a motlakase oa DC electromagnet hangata ke 24V, 'me molemo oa eona ke hore o sebetsa ka botšepehi, o ke ke oa chesa ka lebaka la spore e khomarelang,' me o phela nako e telele.

Ea boraro, ho aroloa ha li-valve tsa solenoid

1, valve ea solenoid e sebetsang ka kotloloho
Ha matla a le teng, matla a makenete a motlakase a hlahisoang ke khoele ea motlakase a phahamisa karolo e koalang setulong, ebe valve e bitsoa. Ha matla a tima, valve ea solenoid e nyamela, selemo se hatella karolo e koalang setulong, 'me valve e koetsoe. E tšoauoa ka ts'ebetso e tloaelehileng ea vacuum, khatello e mpe le khatello ea zero, empa bophara ka kakaretso ha bo fete 25mm.

2, valve ea sefofane sa solenoid
(Molao-motheo o sebetsang oa valve ea solenoid)

Ha e sebelisoa, matla a makenete a motlakase a bula lesoba la sefofane, khatello ea kamore e ka holimo e theoha ka potlako, e etsa phapang ea khatello e tlaase le e phahameng ho potoloha karolo e koalang, khatello ea mokelikeli e sutumelletsa karolo e koalang ho ea holimo, ebe valve ea buleha. Ha motlakase o tima, matla a selemo a koala lesoba la sefofane, 'me khatello ea ho kena e etsa phapang e tlase le e phahameng ea khatello ho potoloha karolo e koalang ea valve ka lesoba la bypass ka potlako,' me khatello ea mokelikeli e sutumelletsa karolo e koalang hore e theohele fatše le ho koala belofo. E tšoauoa ka moeli o ka holimo oa khatello ea mokelikeli 'me e ka kenngoa ka mokhoa o ikemetseng (ho etsoa ka mokhoa o ikhethileng) empa e tlameha ho kopana le maemo a phapang ea khatello ea mokelikeli.
