High Quality Common Rail Control Valve Set Gungano F00RJ01533 ye Diesel Injector 0445120063

Injector tsono vharafu musangano yekuongorora nzira
(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 kuti usimudze kudzvinyirira ku 23 ~ 24 MPa uye kuyera nguva yekumanikidzwa kudonha kubva pa20 MPa kusvika ku18 MPa.Mhedzisiro yemhedzisiro uye zvigadzirwa zvakajairwa Kuenzanisa, inofanirwa kunge iri pakati pematanho anodiwa.2) Chisimbiso chekuvhara bvunzo.Shandisa 20# chiedza chemafuta edhiziri pabhenji rekuedza rine pressure accumulator, tanga wagadzirisa kudzvanywa kwejekiseni remafuta kune kudzvanywa kwakatarwa kwe12.5 MPa, wobva wawedzera kudzvanywa kwemafuta ne 0.1 MPa yega 3 ~ 5s zvakaenzana kusvika jekiseni remafuta ratanga., kuti ucherechedze kunaka kwekuvharisa, kudonha kwemafuta kushoma kunobvumidzwa, uye dhayamita rekudonha kwemafuta haapfuuri 5mm (nzvimbo yechigaro haigayana) kana dhayamita i3mm (nzvimbo yechigaro inogaya mumwe nemumwe. )Asi kwete mune convex spherical chimiro.
(3) Spray test.Shandisa 20# chiedza chemafuta edhiziri pabhenji rekuedza, gadzirisa jekiseni remafuta kusvika 12.5 MPa, uye ita bvunzo yekupfapfaidza ne40 ~ 80 nguva dzejekiseni paminiti.Hunhu hwekupfapfaidza hunofanirwa kuzadzisa zvinodiwa zvinotevera: D. Mafuta akapfapfaidzwa anofanira kuve atomize.Hakufanirwe kuve nekuputika kwemafuta zvimedu uye kusaenzana kwenzvimbo kwehukobvu hunogona kuonekwa nemeso asina kupfeka.2. Kutanga uye kupera kwejekiseni kunofanira kuva pachena uye ruzha runofanira kuva rwakajeka.3 Jekiseni risati ratanga uye mushure mekunge jekiseni rapera, hapana kubuda kwemafuta kunobvumidzwa pagomba rejekiseni, asi hunyoro hunobvumidzwa.
(4) Spray angle check.Tarisa neziso rakashama, enzanisa kona yekupfapfaidza pasi pesimba rejekiseni remafuta rinoshandiswa painjini yedhiziri nemuenzaniso, uye kutsauka pakati pemutsara wepakati weiyo yekupfapfaidza angle yejekiseni yemafuta uye mutsara wepakati wejekitari yemafuta haina kukura. kupfuura 4°30.The spray cone angle inocherechedzwa mukati me100mm.
(5) Sliding test.Chenesa nekuzora mativi acho nemafuta edhiziri akanyatso sefa.Kana iyo valve yetsono iri pa 45 ° kusvika panzvimbo yakatarisa, dhonza valve yetsono kunze kwemuviri wevhavha yetsono ne 1/3 yehurefu hwayo, itendeudze kune chero nzvimbo uye irege iende.Huremu pachahwo hunotsvedza zvakasununguka pasina chipingamupinyi.
