Molao-motheo o sebetsang oa valve ea solenoid ea excavator

Motho ea epollang haholo-holo o sebelisa valve ea solenoid e sebetsang ka ho toba, e nang le melemo ea ho laola habonolo, ketso e potlakileng, ho fihlella habonolo ho laola hole, 'me e ka sebetsa ka tloaelo tlas'a vacuum, khatello e mpe le khatello ea zero. The excavator solenoid valve e na le kamore e koetsoeng ka hare, 'mele oa valve o bohareng ba phaposi,' me lipheletso tse peli tsa 'mele oa li-valve li hlophisitsoe ka li-electromagnets ho latela litlhoko, kapa pheletso e le' ngoe feela e hlophisoa ka li-electromagnets. U sebelisa matla a khoheli a hlahisoang ke molao-motheo oa inductance, spool ea taolo e tsamaea ho fihlela phetoho ea potoloho ea oli, ha coil ea electromagnet e matlafatsoa, ​​​​electromagnet e tla hula ka lehlakoreng le leng, ebe e sutumelletsa spool hore e tsamaee ka lehlakoreng la ho hula, ka hona e thibela kapa e pepesa masoba a fapaneng a oli, 'me oli e tla kena liphaepheng tse fapaneng ho latela litaelo. Haeba coil ea solenoid ea valve ea solenoid e chesoa kapa e khaotsoe, e ke ke ea hlahisa matla a khoheli, 'me motsoako oa valve o ke ke oa sisinyeha,' me moepolli ha a khone ho etsa mesebetsi e amanang le eona.

Valve ea solenoid e sebelisa electromagnet ho sututsa konokono ea valve ho laola tsela eo moea o hatelitsoeng ka eona, ka hona e laolang tataiso ea switch ea pneumatic actuator.
Electromagnet e sebelisoang ho sebelisa valve ea solenoid e arotsoe ka AC le DC:

1. Matla a motlakase a AC electromagnet hangata ke 220 volts. E khetholloa ka matla a maholo a ho qala, nako e khutšoanyane ea ho khutlisetsa morao le theko e tlaase. Leha ho le joalo, ha mokokotlo oa valve o khomaretsoe kapa ho huloa ha hoa lekana 'me mokokotlo oa tšepe o sa angoe, motlakase oa motlakase o bonolo ho chesa ka lebaka la hona joale ho feteletseng, kahoo ts'epahalo ea ho sebetsa e fokola, phello ea ketso le bophelo. e tlase.

2.DC motlakase oa motlakase oa motlakase hangata ke 24 volts. Melemo ea eona ke mosebetsi o ka tšeptjoang, eseng hobane spore e khomaretsoe ebile e chesitsoe, bophelo bo bolelele, boholo bo nyane, empa matla a qalang a manyane ho feta mabone a motlakase a AC, mme ha ho se na motlakase oa DC, tlhokahalo ea lisebelisoa tsa ho lokisa.
Bakeng sa ho ntlafatsa ts'epahalo ea ts'ebetso le bophelo ba valve ea ho khutlisa motlakase, lilemong tsa morao tjena, motlakase o metsi o ntse o sebelisoa haholo lapeng le kantle ho naha, motlakase ona oa motlakase le molamu oa slide valve push ha o hloke ho tiisoa, ho felisa likhohlano. Lesale la ho tiisa ka sebopeho sa O, khoele ea eona ea motlakase kantle e tiisitsoe ka kotloloho ka polasetiki ea boenjiniere, eseng khetla e 'ngoe ea tšepe, e netefatsang ho kenella, empa hape e thusa ho qhala mocheso, mosebetsi o ka tšeptjoang, Tšusumetso e tlase, bophelo bo bolelele.
Ho fihlela joale, valve ea solenoid lapeng le linaheng tse ling e arotsoe ka mekhahlelo e meraro ka molao-motheo (e leng: mofuta oa ho sebetsa ka ho toba, mofuta oa sefofane sa ngoana), 'me ho tloha phapang ea sebopeho sa li-valve disc le phapang ea thepa le molao-motheo e arotsoe ka lihlopha tse tšeletseng. (sebopeho sa diaphragm se sebetsang ka kotloloho, sebopeho sa poleiti e habeli, sebopeho sa filimi ea sefofane, sebopeho sa piston se sebetsang ka kotloloho, sebopeho sa piston se sebetsang ka kotloloho, sebopeho sa piston ea sefofane).

The electromagnetic valve ea excavator e phetha karolo ea ho laola.
 

1, valve ea solenoid ke sesebelisoa sa indasteri se laoloang ke motlakase, se sebelisetsoang ho laola likarolo tsa motheo tsa mokelikeli o ikemetseng, ke oa actuator, o sa felle feela ho hydraulic, pneumatic. E sebelisoa lits'ebetsong tsa taolo ea indasteri ho lokisa tataiso ea mecha ea litaba, phallo, lebelo le likarolo tse ling.

2, valve ea solenoid e ka kopanngoa le lipotoloho tse fapaneng ho finyella taolo e lakatsehang, 'me ho nepahala le ho feto-fetoha ha taolo ho ka tiisetsoa. Ho na le mefuta e mengata ea li-valve tsa solenoid, li-valve tse fapaneng tsa solenoid li phetha karolo ea maemo a fapaneng a tsamaiso ea taolo, tse sebelisoang ka ho fetisisa ke li-valve tsa ho hlahloba, li-valve tsa tšireletso, li-valve tsa ho laola tataiso, li-valve tse laolang lebelo joalo-joalo.
