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 dzebvunzo dzinoenderana neChigadzirwa chakajairwa chinofanira kuenzaniswa nemhando inodiwa.

(2) Muedzo wekuisa chisimbiso chechigaro.Shandisa 20# yakareruka mafuta edhiziri pabhenji rekuyedza rine pressure accumulator, tanga wagadzirisa kudzvanywa kwejekiseni remafuta kune kudzvanywa kwakatarwa 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 kushoma 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 e40-80 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 kona yespray.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 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.
