380-9849 Excavator hydraulic pump proportional solenoid valve 172-2392

Proportional valve failure lisosa le tharollo

(1) Ho hloleha ho lekana ha motlakase
Ka lebaka la botsofali, khokahano e mpe ea sokete ea wiring [base] ea polaka le ho chesetsoa ha lead to ea electromagnet, proportional electromagnet ha e khone ho sebetsa (ha e khone ho jara hona joale).Ka nako ena, meter ea motlakase e ka sebelisoa ho lemoha, haeba khanyetso e fumanoa e le e sa feleng, u ka boela ua etsa weld lead, lokisa sokete le ho koala sokete ka thata.
Ho hloleha ha terata ho kenyelletsa botsofali ba li-coil, ho khathala ha terata, ho robeha ha terata ka hare le ho nyoloha ho feteletseng ha mocheso.
Phenomenon.Ho nyoloha ha mocheso oa coil ho hoholo haholo ho etsa hore matla a tsoang ho proportional electromagnet ha a lekana, 'me tse ling kaofela li tla etsa hore proportional electromagnet e se ke ea sebetsa.
Etsa.Bakeng sa mocheso oa mocheso oa coil o moholo haholo, o ka hlahloba hore na motlakase o moholo haholo, hore na terata ea coil enameled e futsanehile, valve.
Hore na motheo o khomaretsoe ka lebaka la litšila, joalo-joalo, fumana mabaka le ho a felisa ka bonngoe;Bakeng sa mela e robehileng, e chesitsoeng le liketsahalo tse ling, mohala o tlameha ho nkeloa sebaka
Sefane
Lebaka le ka sehloohong la kopano ea lihlomo ke hore lihlomo le para ea khohlano e entsoeng ke seaparo sa letsoho sa tataiso ea makenete nakong ea ts'ebeliso, e leng se bakang keketseho ea matla a hysteresis ea valve.Ho na le molamu oa tataiso ea molamu le pelo e fapaneng ea armature, hape e tla etsa hore matla a hysteresis a eketsehe, a tlameha ho tlosoa.
Ntle le.
④ Hobane tjheseletsa ha e matla, kapa tlasa ts'ebetso ea proportional valve pulse pressure e sebelisoang, ho chesoa ha letsoho la tataiso ea makenete ho robehile.
Crack, e etsang hore electromagnet e lekantsoeng e lahleheloe ke tšebetso.
