Ho mefuta eohle ea likoloi, libese, literekere le lisebelisoa tse khethehileng, li-valve tsa solenoid li sebelisoa haholo ho laola ho phalla ha metsi le likhase.Bala ka hore na li-valve tsa solenoid ke eng, li hlophisitsoe joang le hore na li sebetsa joang, le hore na li lula sebakeng sefe thepa ea likoloi sehloohong sena.
Sephahla sa solenoid ke eng, 'me se sebelisoa hokae?
Solenoid valve ke sesebelisoa sa electromechanical bakeng sa taolo e hole ea phallo ea likhase le lino.
Ho theknoloji ea likoloi, li-valve tsa solenoid li sebelisoa lits'ebetsong tse fapaneng:
- Tsamaisong ea moea;
- Ka tsamaiso ea haeteroliki;
- Ka tsamaiso ea mafura;
- Lits'ebetsong tse thusang - bakeng sa taolo e hole ea likarolo tsa phetisetso, sethala sa ho lahla, li-attachments le lisebelisoa tse ling.
Ka nako e ts'oanang, li-valve tsa solenoid li rarolla mesebetsi e 'meli e meholo:
- Ho laola ho phalla ha mochine o sebetsang - phepelo ea moea o hatelitsoeng kapa oli ho lihlopha tse sa tšoaneng, ho itšetlehile ka mokhoa oa ho sebetsa oa tsamaiso;
- Ho thibela phepelo ea sebaka sa ho sebetsa maemong a tšohanyetso.
Mesebetsi ena e rarolloa ke li-valve tsa solenoid tsa mefuta le meralo e fapaneng, e hlokang ho hlalosoa ka botlalo.
Mefuta ea li-valve tsa solenoid
Pele ho tsohle, li-valve tsa solenoid li arotsoe ka lihlopha tse peli ho ea ka mofuta oa mochini o sebetsang:
- li-valve tsa moea - pneumatic;
- Mekelikeli - li-valve bakeng sa sistimi ea mafura le sistimi ea haeteroliki bakeng sa merero e fapaneng.
Ho ea ka palo ea phallo ea mochini o sebetsang le likarolo tsa ts'ebetso, li-valve li arotsoe ka mefuta e 'meli:
- Litsela tse peli - li na le lipeipi tse peli feela.
- Litsela tse tharo - li na le lipeipi tse tharo.
Li-valve tsa litsela tse peli li na le liphaephe tse peli - ho kena le ho tsoa, pakeng tsa tsona sebaka se sebetsang se phalla ka tsela e le 'ngoe feela.Pakeng tsa liphaephe ho na le valve e ka bulang kapa ea koala phallo ea mochine o sebetsang, ho netefatsa hore o fana ka li-unit.
Li-valve tsa litsela tse tharo li na le li-nozzle tse tharo tse ka kopanngoang ka mefuta e sa tšoaneng.Ka mohlala, litsamaiso tsa moea li atisa ho sebelisa li-valve tse nang le liphaephe tse kenang le tse peli, 'me libakeng tse sa tšoaneng tsa ntho ea taolo, moea o hatelitsoeng o tsoang pipe e kenang o ka fetisetsoa ho e' ngoe ea liphaephe tse kenang.Ka lehlakoreng le leng, ho li-valve tsa EPHX (economizer e se nang letho e qobelloang) ho na le mokelikeli o le mong le liphaephe tse peli tsa ho noa, tse fanang ka khatello e tloaelehileng ea sepakapaka le ho fokotseha ho tsamaiso ea carburetor idling.
Li-valve tsa litsela tse peli li arotsoe ka mefuta e 'meli ho latela boemo ba karolo ea taolo ha electromagnet e felloa ke matla:
- Hangata e butsoe (NO) - valve e bulehile;
- Hangata e koetsoe (NC) - valve e koetsoe.
Ho ea ka mofuta oa actuator le taolo, li-valve li arotsoe ka mefuta e 'meli:
- Li-valve tsa ketso e tobileng - ho phalla ha mochine o sebetsang ho laoloa feela ke matla a hlahisoang ke motlakase oa motlakase;
- Li-valve tsa pilot solenoid - phallo ea mochine o sebetsang o laoloa ka karolo e itseng ka ho sebelisa khatello ea bohareng ka boeona.
Likoloi le literekere, li-valve tse bonolo tse sebetsang ka kotloloho hangata li sebelisoa.
Hape, li-valve li fapana ka litšobotsi tsa ts'ebetso (voltage ea phepelo ea 12 kapa 24 V, bore ea lebitso le tse ling) le likarolo tsa moralo.Ka lehlakoreng le leng, ho bohlokoa ho bua ka li-valve, tse ka bokelloang ka likotoana tsa likotoana tse 2-4 - ka lebaka la boemo bo itseng ba liphaephe le li-fasteners (li-eyelets), li ka kopanngoa ka mohaho o le mong o nang le palo e kholo ea ho kenya le ho kenya letsoho. liphaephe tse tsoang.
Sebopeho se akaretsang le molao-motheo oa ts'ebetso ea li-valve tsa solenoid
Li-valve tsohle tsa solenoid, ho sa tsotelehe mofuta le morero, li na le moralo o tšoanang, 'me li na le likarolo tse' maloa tsa mantlha:
- Electromagnet (solenoid) e nang le armature ea moralo o mong kapa o mong;
- Karolo ea ho laola / ho notlela (kapa likarolo) tse hokahaneng le armature ea electromagnet;
- Li-cavities le liteishene tsa phallo ea mochini o sebetsang, o hokahaneng le li-fittings kapa li-nozzles 'meleng;- Lihlopha.
Hape, valve e ka jara likarolo tse fapaneng tse thusang - lisebelisoa tsa ho lokisa tsitsipano ea liliba kapa ho otla ha sesebelisoa sa taolo, lisebelisoa tsa drainage, li sebetsana le taolo ea taolo ea phallo ea mochini o sebetsang, li-switches tsa ho laola lisebelisoa tse ling ho latela naha. ea valve, li-filters, joalo-joalo.
Li-valve li arotsoe ka lihlopha tse tharo ho latela mofuta le moralo oa karolo ea taolo:
- Spool - karolo ea taolo e entsoe ka mokhoa oa spool, e ka tsamaisang phallo ea mokhoa oa ho sebetsa ka likanale;
- Membrane - karolo ea taolo e entsoe ka mokhoa oa lera la elastic;
- Piston - karolo ea taolo e entsoe ka mokhoa oa piston e haufi le setulo.
Tabeng ena, valve e ka 'na ea e-ba le karolo e le' ngoe, tse peli kapa ho feta tse laolang tse amanang le letsoho le le leng la electromagnet.
Molao-motheo o sebetsang oa valve ea solenoid o bonolo haholo.Nahana ka ts'ebetso ea "diaphragm" e bonolo ka ho fetisisa ea litsela tse peli eo hangata e koetsoeng e sebelisoang lits'ebetsong tsa phepelo ea mafura.Ha valve e felloa ke matla, "armature" e hatelloa khahlanong le diaphragm ka ketso ea seliba, e thibelang mocha le ho thibela mokelikeli ho phalla ho feta tsamaisong.Ha hona joale e sebelisoa ho electromagnet, matla a khoheli a hlaha ha a ntse a tsoelipana, ka lebaka leo armature e huleloang ka hare - motsotso ona lera, le seng le sa hatelloa ke armature, le phahama tlas'a tšusumetso ea khatello ea mosebetsi. e mahareng mme e bula kanale.Ka mor'a ho tlosoa ha hona joale ho tloha ho electromagnet, armature tlas'a ketso ea selemo e tla khutlela sebakeng sa eona sa pele, tobetsa lera ebe o thibela mocha.
Li-valve tsa litsela tse peli li sebetsa ka tsela e tšoanang, empa li sebelisa li-spools kapa lisebelisoa tsa ho laola mofuta oa piston ho e-na le diaphragm.Ka mohlala, nahana ka moralo le ts'ebetso ea valve ea EPHX ea likoloi tsa carburetor.Ha motlakase o felloa ke matla, letsoho le phahamisetsoa ka tlas'a ts'ebetso ea selemo, 'me ntho ea ho koala e koala sekoahelo se ka holimo, se kopanya mahlakoreng le likarolo tse tlaase (sepakapaka) - tabeng ena, khatello ea sepakapaka e sebelisoa ho EPHH. valve ea pneumatic, e koetsoe 'me tsamaiso ea carburetor idling ha e sebetse.Ha hona joale e sebelisoa ho electromagnet, armature e khutlisetsoa morao, e hlōla matla a selemo, e koala sekoahelo se ka tlaase, ha se ntse se bula se ka holimo, se hokahaneng le pipe ea ho kenya enjene (moo khatello e fokolitsoeng e bonoang) - tabeng ena, vacuum e sebelisoa ho EPHH pneumatic valve, e bula le ho bulela tsamaiso e sa sebetseng.
Li-valve tsa Solenoid li ts'epahala haholo ebile ha li na boikakaso ts'ebetsong, li na le sesebelisoa sa bohlokoa (ho fihlela ho likete tse makholo a 'maloa),' me, joalo ka molao, ha li hloke tlhokomelo e khethehileng.Leha ho le joalo, ha ho e-na le ho se sebetse, valve leha e le efe e tlameha ho nkeloa sebaka kapele kamoo ho ka khonehang - feela tabeng ena ts'ebetso e hlokahalang le polokeho ea koloi e tla tiisetsoa.
