Mhedzisiro yedhayamita yenozzle, kudzvanywa kwejekiseni uye ambient tembiricha pane yekupfapfaidza maitiro muinjini yedhiziri(Chikamu 4)

Sezvo girafu richiratidza kureba kwekupinda paFigure 9 neFigure 10 uchishandisa ambient yakasiyana.

tembiricha ye 0.12 mm uye 0.2 mm nozzle dhayamita inoramba ichiwedzera nenguva inotorwa uye zvese zvetembiricha kureba kwekupinda hakupi zvakanyanya kusiyana.Izvi zvinokonzerwa nehuwandu hwepakati petembiricha kwete yakanyanya kukura.Nekudaro, kudzvanywa kwejekiseni kunopesvedzera kureba kwekupinda kwepfapfaidzo, uko kudzvanywa kwejekiseni kwakasiyana kuri 40 MPa, 70 MPa uye 140 MPa ine ambient pressure 1 MPa pamhepo yemhepo.Seyakanyanya kudzvanywa jekiseni, kureba kwekupinda kunofurira.Izvi zvinodaro nekuti iyo pfapfaidzo yakarambwa nekumanikidzwa kwe ambient.

Mufananidzo 11 uye 12 inoratidza magirafu ehurefu hwekuparadzana ne 0.12 mm uye 0.2 mm nozzle dhayamita.Pane mhedzisiro yekushanduka pane tembiricha 500 K, uko jekiseni dzvinyiriro 140 MPa uye nozzle dhayamita 0.2 mm inowedzera zvinoshamisa kubva pa1 mm yakamira kusvika pa2.3 mm.Izvi zvichida nekuda kwekuti donhwe harina kuparara uye nekurebesa, uku kudanwa sechikamu che ligament.Enzanisa kune tembiricha 700 K pa140 MPa uye 0.2 mm yekuparadzana kureba inoyerera yakatsiga nenguva.Saka tembiricha inopesvedzera kune yakakwira ambient tembiricha inoshandiswa, iyo ipfupi yekuparadzana kureba inoitika pachikamu chepakati.

4. Mhedziso

Ichi chidzidzo chakaratidza kuyedzerwa kuyerera kwehuturu inoyerera mumuromo wepfapfaidzo isati yapiswa.Majekiseni akaderera mukamuri anozokanganisa kuparara kwemafuta ekupfapfaidza kusvika kumadonhwe akanaka kwazvo asati atanga kubatidza mafuta.Shanduko yetembiricha mukamuri inokanganisawo hurefu hwekupfapfaidza kupinda.Pamatembiricha epamusoro, mafuta anobuda nyore nyore uye anobatidza mafuta acho pachawo.Zvakare, iyo dhayamita yemhino inokanganisa zvakare kureba kweiyo muromo wekupfapfaidza sekufurirwa neiyo yepamusoro jekiseni kumanikidza uko kureba kwekuparadzana kuri kupfupika.
