Njira yoyendera injector yamafuta

Kuwunika kwa gulu la valve ya singano kumaphatikizapo: kuyang'ana pamwamba pazithunzi, kuyang'ana kotsetsereka, kuyang'anitsitsa kusindikiza ndi kuyang'anira kupopera, etc.

3.1 Chiwongolero cha cylindrical pamwamba pa valve ya singano ndi thupi la jekeseni sayenera kukhala ndi zowonongeka zowonongeka ndi zowonongeka, ndipo malo osindikizira atha.

3.2 Pendekerani valavu ya singano pamalo a 45 °, tulutsani valavu ya singano kunja kwa thupi la valavu pafupi ndi 1/3, ndipo imatha kulowera pang'onopang'ono mu thupi la valve pansi pa mphamvu yake popanda chodabwitsa chilichonse.

3.3 Ikani anasonkhana mafuta jekeseni pa choyesa mafuta jakisoni, ndi kusintha masika kuthamanga pang'ono kuposa muyezo kutsegula mafuta jekeseni kuthamanga kwa jekeseni mafuta (nthawi zambiri 12 ~ 14MPa apamwamba kuposa 3 ~ 5MPa). Ngati mphamvu yamafuta ikwera kufika ku 20MPa, yesani nthawi yomwe imatengera kuti mphamvu yamafuta igwere kuchokera ku 20MPa kupita ku 18MPa, osachepera 9 ~ 12s.

Kupanda kutero, kusindikizako sikukuyenda bwino, ndipo sipayenera kukhala madontho owoneka bwino amafuta kuzungulira dzenje la nozzle. Ngati palibe choyezera jekeseni wamafuta, jekeseni yamafuta yokonzedwayo imatha kuyikidwa mwachindunji pampopi yojambulira mafuta ya injini ya dizilo kuti iyesedwe.

3.4 Sinthani ku kuthamanga kwa jekeseni wamafuta a 12MPa, ndi mafuta opopera pa liwiro la pampu pafupifupi 60 ~ 70 nthawi / mphindi. Mafuta opopera ayenera kukhala ofewa komanso ofanana ndi atomu, ndipo payenera kukhala phokoso lomveka komanso lomveka. Palibe kudontha kwa mafuta, ndipo palibe kutayikira kwakukulu kuzungulira bowo la jekeseni la thupi la jekeseni.

Ikani pepala loyera 10 ~ 20cm kutali ndi mphuno pansi pa jekeseni, ndipo yesani mtunda h kuchokera pamphuno kupita ku banga lamafuta ndi m'mimba mwake d wa banga lamafuta. Kenako muwerenge motsatira ndondomekoyi.

Pezani ngodya kuchokera ku trigonometric ntchito, ndipo kawiri ngodyayo ndi ngodya yojambulira mafuta. Ngati zofunikira sizingakwaniritsidwe kudzera mu ntchito yomwe ili pamwambapa, jekeseni yatsopano yamafuta iyenera kusinthidwa.

Pomaliza, mfundo zotsatirazi ziyenera kuzindikirika:

(1) Samalani ndi code yomwe ili pamwambayi mukamagwiritsa ntchito jekeseni wamafuta kuti musagwiritse ntchito molakwika. Apo ayi, zofunikira zoyenera sizidzapezeka, mafuta adzawotchedwa mosakwanira kapena osawotchera, utsi wakuda udzatulutsidwa kuchokera ku mpweya, mafuta adzawonongeka, ndipo mphamvu idzakhudzidwa.

(2) Pokonza mphamvu ya jekeseni wa mafuta, musalole kuti khungu kapena zala zibwere pafupi ndi bowo la mphuno ndikubayidwa ndi jekeseni. Chifukwa chakuti mafuta a dizilo othamanga kwambiri amalowa pakhungu n’kuthamangira m’mitsempha ya magazi, amakhala ndi poizoni m’thupi la munthu. Chisamaliro chapadera chiyenera kuperekedwa kuti musayang'ane kwambiri momwe jekeseni wamafuta amakhalira kuti mupewe kuwonongeka kwa maso.
