Excavator solenoid valve TM70402 24V hydraulic pombi proportional solenoid valve

 Excavator electromagnetic relief valve kukanganisa uye kugadzirisa nzira:

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.

g, rubber ring kupfeka uye kwete kutsiva panguva.

System pressure haigone 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.

Chikonzero chechipiri: Varuvhu yekutyaira haina kunaka
① Chitubu chekugadzirisa chakaputsika kana kuti chisina kutakurwa,
② Taper valve kana simbi bhora haina kuiswa,
③ Iyo taper valve yakatyoka. Kugadzirisa: Dzorera zvikamu zvakakuvadzwa kana kutsiva zvikamu kuti udzorere valve yekufambisa basa remazuva ose.

Chikonzero chechitatu: Iyo remote control port solenoid valve haina simba pa (kazhinji yakavhurika) kana siraidhi vharafu inonamira.
Mhinduro: Tarisa tambo yemagetsi kuti uone kana magetsi akabatanidzwa; Kana zvakajairika, zvinoratidza kuti slide valve inogona kunamatira, uye zvikamu zvisina kunaka zvinofanira kugadziriswa kana kuchinjwa.
