Common Rail Control Valve Set Gungano F00VC01037 & Injector Spare Part yeInjector 0445110112 0445110187

Inzira yekuongorora yetsono valve musangano wemafuta injector

(1) Muedzo wekusimba kwemutsipa. Shandisa mafuta akasanganiswa kana 20# yakareruka dhiziri, uye shandisa decompression nzira kuita pane yakakosha bhenji rekuyedza. Panguva yekuedzwa, shandisa pombi yemaoko kusimudza kudzvinyirira ku 23-24 MPa, uye kuyera nguva yekumanikidzwa kudonha kubva pa20 MPa kusvika 18 MPa. Mhedzisiro yebvunzo inoenderana neChigadzirwa chakajairwa chinofanira kuenzaniswa nechiyero chinodiwa.

(2) Seat sealing test. Shandisa 20# yakareruka mafuta edhiziri pabhenji rekuyedza ine pressure accumulator, tanga wagadzirisa kudzvanywa kwejekiseni remafuta kune yakatsanangurwa kudzvanywa kwe12.5 MPa, wobva wawedzera kudzvanywa kwemafuta ne 0.1 MPa ese matatu kusvika ku5 s zvakaenzana kusvika panotanga jekiseni. Oiri, tarisa kuvharika kwemhando, kudonha kwemafuta kudiki kunobvumidzwa, uye dhayamita rekudonha kwemafuta haapfuuri 5 mm (chigaro nepamusoro hazvikuyani) kana 3 mm padhayamita (chigaro uye chigaro. pamusoro pekukuya). Asi kwete mune convex spherical chimiro.

(3) Spray test. Shandisa 20# yakareruka mafuta edhiziri pabhenji rekuyedza, gadzirisa jekiseni remafuta kusvika 12.5 MPa, uye ita bvunzo yekupfapfaidza nehuwandu hwemajekiseni makumi mana-80 nguva /min. 

Hunhu hwekupfapfaidza hunofanirwa kuita zvinotevera zvinodiwa:

①Mafuta anoiswa jekiseni anofanirwa kuve atomi, uye hapafanirwe kuve nemafuta anoputika zvimedu uye kusaenzana kwenzvimbo kunogona kuonekwa neziso.

②Kutanga uye kupera kwekupfapfaidza kunofanira kunge kuri pachena, uye ruzha runofanira kunge rwakajeka.

③Kusati kwatanga kupfapfaidza uye mushure mekupera kwekupfapfaidza, kubuda kwemafuta hakubvumidzwe pagomba rekupfapfaidza, asi hunyoro hunobvumidzwa.

(4) Tarisa angle yekupfapfaidza. Tarisa neziso rakashama, enzanisa kona yekupfapfaidza pasi pesimba rejekiseni remafuta rinoshandiswa painjini yedhiziri nemuenzaniso, uye kutsauka pakati pemutsara wepakati wekona yekupfapfaidza yejekiseni yemafuta uye mutsara wepakati wejekitari yemafuta haina kukura. kupfuura 4°30'. The spray cone angle inocherechedzwa mukati me100 mm.

(5) Sliding test. Chenesa nekuzora mativi acho nemafuta edhiziri akanyatso sefa. Kana iyo valve yetsono iri pa45° kusvika panzvimbo yakachinjika, dhonza vharafu yetsono kunze kwemuviri wetsono ne 1/3 yehurefu hwayo. Shandura kune chero nzvimbo uye rega iende. Huremu pachahwo hunotsvedza zvakasununguka pasina chipingamupinyi.
