Excavator solenoid valve 714-11-16840 proportional solenoid valve

1. System pressure fluctuation

Zvikonzero zvikuru zvekuchinja kwepressure ndezvi:

① Zvisungo zvinogadzirisa kudzvanywa kunoita kuti nati yekukiya isununguke nekuda kwekudengenyeka, zvichikonzera kushanduka kwesimba;

② Mafuta eHydraulic haana kuchena, kune guruva duku, kuitira kuti iyo huru spool inotsvedza haina kushanduka. Zvichikonzera kuchinja kusingaenzaniswi kwekumanikidza. Dzimwe nguva vharafu inoputika;

③ Iyo huru valve spool haina kutsvedzerera, zvichiita kuti gomba rekunyorovesa rivharwe kana rapfuura;

(4) Iyo conical pamusoro peiyo huru yevhavha core haina kusangana zvakanaka nekoni yechigaro chevharuvhu, uye haina kunyatsokuyiwa;

⑤ Gomba rekunyorovesa repakati pevharuvhu rakakura zvakanyanya uye haritambi basa rekunyorovesa;

Iyo pilot valve inogadzirisa kubhenda kwechirimo, zvichikonzera kusabatana kwakashata pakati pe spool nechigaro chekoni, kupfeka zvisina kuenzana.

Mhinduro:

① Geza tangi yemafuta uye pombi nguva nenguva, uye kusefa iyo hydraulic oiri inopinda mutangi remafuta uye pombi system;

(2) Kana paine sefa mupombi, chikamu chechipiri chesefa chinofanira kuwedzerwa, kana kurongeka kwesefa kwechikamu chechipiri kunofanira kutsiviwa; Bvisa uye uchenese zvikamu zvevharuvhu uye kutsiva yakachena hydraulic oiri;

③ Gadzirisa kana kutsiva zvikamu zvisina kukodzera;

④ Deredza mvura yekunyorovesa aperture zvakakodzera.

2. System pressure haigoni kukwira zvachose

Chikonzero 1:

① Gomba guru rekudzikisa spool rakavharwa, senge kuungana kwespool hombe haina kucheneswa, oiri yakasviba zvakanyanya kana gungano nemarara;

② Hunhu husina kunaka hwegungano, kurongeka kwakashata panguva yegungano, kusagadzirika kwakashata kwepakati pakati pemavharuvhu, spool huru yakanamira panzvimbo yakavhurika, kunaka kwegungano rakashata;

③ Iyo hombe spool reset chitubu chakatyoka kana kukotama, kuitira kuti spool huru haigone kugadzikiswa patsva.

Mhinduro:

① Bvisa gomba guru rekuchenesa vharafu uye uunganidze zvakare;

② Sefa kana kutsiva mafuta;

③ Simbisa chivharo chevhavha yekusimbisa sikururu kuti utsive chitubu chakaputsika.
