Excavator accessories hydraulic solenoid valve yepakutanga TM68501 proportional solenoid valve

Iyo solenoid valve pa hydraulic pombi kazhinji ine maviri, imwe iTVC solenoid vharafu, imwe yacho LS-EPC solenoid vharafu, yekutanga ine basa rekuona chiratidzo kubva kune injini yekumhanyisa sensor, kugadzirisa injini simba uye hydraulic pombi. magetsi machisa, kana akakuvadzwa, ingave injini izere nemota, haina simba rakakwana, kana injini yakaoma kutanga.
Iyo yekupedzisira ine basa rekuona mashandiro emutyairi uye shanduko muhukuru hwemutoro wekunze, kana ikakuvadzwa, zvinokonzeresa kushaya simba mukuchera, kunonoka kushanda kwemuchina wese, kutadza kuita micro-operation, uye pasina giya rinomhanya. Izvo zvinofanirwa kucherechedzwa kuti pane imwe TVC solenoid valve pamberi uye mushure mepombi, uye imwe chete LS-EPC solenoid valve.
Hydraulic pombi drive shaft haigone kumira radial simba uye axial simba, saka hazvibvumidzwe kuisa mavhiri ebhandi, magiya, sprockets zvakananga kumucheto weshaft, kazhinji nekubatanidza kubatanidza dhiraivha shaft uye pombi drive shaft.
Kana nekuda kwezvikonzero zvekugadzira, iyo coaxial dhigirii yepombi uye yekubatanidza inodarika mwero, uye paine kutsauka panguva yegungano, iyo centrifugal simba inowedzera deformation yekubatanidza pamwe nekuwedzera kwepombi kumhanya, uye simba recentrifugal rinowedzera. Zvinokonzera kutenderera kwakashata, mhedzisiro yekudengenyeka uye ruzha, nokudaro kukanganisa hupenyu hwebasa hwepombi. Uye zvakare, kune zvimwe zvinofurira zvinhu zvakaita sekubatanidza pini kusunungura uye kwete panguva yakakodzera tightenin.

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.
