XG808 Pilot solenoid vharafu Shagong Excavator solenoid valve spool 16mm excavator chikamu SV38-30

Ese marudzi eakarukwa katuriji mavharuvhu: chimiro, kushanda musimboti uye kuita

Chekutanga, izvo zvekutanga kuita zvinodiwa kune hydraulic mavharuvhu:
① Sensitive uye yakavimbika chiito, yakagadzikana basa, diki kamei uye vibration;
Kurasikirwa kwekumanikidzwa kudiki kana mafuta achiyerera;
③ Kuisa chisimbiso kwakanaka, kudonha kwemukati kudiki;
④ Yakareruka uye compact chimiro, kuisirwa nyore, kugadzirisa uye kugadzirisa kwakanaka kwakasiyana-siyana.
Chechipiri, iyo valve yekubatanidza maitiro:
Threaded connection: Muviri wevharuvhu une tambo dzemukati kana dzekunze uye dzakabatana netambo dzepombi.
Kubatana kweFlange: Muviri wevharuvhu une flange uye wakabatana nepombi flange.
Welded connection: Valve body ine welded groove, welded yakabatana nepombi.
Kubatana kweClamp: Muviri wevharuvhu une chibatiso uye chakabatana nepombi clamp.
Sleeve connection: Ivhavha yakabatana nepombi ne sleeve
Clamping yekubatanidza: Iyo yekubatanidza fomu yekurovera yakananga valve uye mapaipi maviri pamwe nemabhaudhi.

Cartridge mavharuvhu anogona kupatsanurwa mumhando mbiri dzekuisa: Slip-in uye Screw-in

Kirasi. Iyo slip-in type inowanzodaidzwa kuti two-way cartridge valve kana logic element, iyo inowanzoda mamwe mavharuvhu ekudzora kutyaira kuti ashande.

Do. Iyo screw type ndiyo yakarongedzerwa cartridge valve inotsanangurwa muchinyorwa chino, iyo inogona kazhinji kupedzisa imwe kana kupfuura yakazvimirira (mushure mekurodha gomba rekukwira)

Hydraulic mabasa, akadai sevhavha yekuyamura, electromagnetic direction valve, flow control valve, balance valve, nezvimwe.

Solenoid valve ishandiso yeindasitiri inodzorwa nemagetsi, inoshandiswa kudzora otomatiki ekutanga zvikamu zvemvura, ine kubuda kwekunze kwakavharika, kudzora kuri nyore kwekudonha kwemukati, kushandiswa kwakachengeteka; Chimiro chakareruka, mutengo wakaderera, nyore kuisa nekuchengetedza; Kukurumidza kuita, simba diki, kutaridzika kwakareruka; Mhando dzakasiyana, dzakasiyana-siyana dzekushandisa uye zvichingodaro. Pane mamwe matambudziko ane solenoid valve. Ngatitarisei zvakanaka kukanganisa kwakajairika kwevharuvhu ye solenoid.

1, coil pfupi dunhu kana kutyora

Detection method: Chekutanga shandisa multimeter kuyera yayo on-off, resistance value inosvika zero kana infinity, zvichiratidza kuti coil short circuit kana open circuit. Kana kukosha kwekupokana kuchiyerwa zvakajairika (zvichida makumi emaeuro muChina), hazvigone kuratidza kuti dambudziko recoil rakanaka. Ndokumbira utarise matambudziko anotevera uye pakupedzisira upfuure bvunzo: Tsvaga diki screwdriver woiisa pedyo nesimbi simbi mune solenoid valve control coil, uye wozopa simba solenoid valve, kana isu tichinzwa magineti, ipapo solenoid valve inoshanda coil yakanaka, kukwenya kwakaipa.
Mhinduro: Tsiva solenoid valve coil.

2, plug/socket dambudziko

Fault phenomenon: Kana solenoid valve iri rudzi rweplug/socket, panogona kunge paine dambudziko resimbi chitubu chesocket (munyori asangana nazvo), dambudziko rewaya papulagi (senge tambo yemagetsi yakabatana newaya yepasi) uye zvimwe zvikonzero hazvigone kutumira simba kune coil. Zvakanakisa kuumba tsika: mushure mekuvhara musokisi
Fixed screw, coil mu spool hunde kuseri kwe fixed nut chipikiri.
