ZQYM-8320 Rail Common Diesel Fuel vp44 Werohanga Pump Whakamātautau Paepae HEUI injector Taputapu Whakamatau papu tester simulator

Ko te mahi a te miihini Diesel e whakawhirinaki ana ki te whakatikatika tika o te papu wero wahie. Ahakoa ko te pae whakamatautau wahie werohanga he tino whakaritenga hangarau hei whakarite i te tika o te whakarereketanga tawhā wahie werohanga papu, ki te kore e tika te mahi me te tiaki, kaore e taea te whakamana i te kounga patuiro o te papu werohanga wahie.

1 Nga whakaritenga hangarau mo te waahi whakamatautau wahie werohanga papu
(1) Ko te hapa o te tauine o te pae whakamatautau kaua e neke ake i te ± 10' i tetahi waahi, me maama te tauine.
(2) Ko te huringa tere inamata i roto i ia hurihanga o te rakau whakaputa o te pae whakamatautau kaua e neke ake i te 1% o te tere whakamatautau ina ko te tere inenga o te kopae tuku o te rakau whakaputa he> 600 r/min; ina ko te tere ≤ 600 r / min, ko te huringa tere inamata kia Kaua e neke atu i te 6 r / min.
(3) Ko te tikanga tatau o te pae whakamatautau kia tika me te tairongo, ka taea te tatau 100 ki te 1000 nga wa i ia taputapu, a ko te hapa tatau o te punaha katoa he 1 te wa.
(4) Ko te rango ine hinu o te pae whakamatautau me whai i te tauine marama me te tika, ko te tauine iti rawa kia kaua e nui ake i te 1% o te tauine katoa, me te hapa o te tauine i roto i te 0.5% o te tauine katoa.
(5) Ko te pehanga hinu hinu o te papa whakamatautau me whakarite kia mau tonu. I te tere tere, ka kati katoa nga putanga, me eke te pehanga teitei: te hiko hinu iti-pēhanga ≥ 0.4 MPa; iahiko hinu pehanga teitei ≥ 34 MPa.
(6) Tawhā o te putorino wahie pehanga teitei mo te patuiro i te papu wero wahie i roto i te raina: te roa×te diameter o waho×te diameter o roto, o te 600 mm×6 mm×2 mm e whakamahia ana mo te patuiro i te papu werohanga wahie e rere ana te wahie. kaua e neke ake i te 300 mm 3 te rahinga tuku; 800 mm×8 mm×39 mm e whakamahia ana mo te tuku i nga papua werohanga wahie me te tuku hinu tohanga nui atu i te 300 mm; 800 mm × 6 mm × 2 mm ka whakamahia mo te tuku i nga papu werohanga wahie kua tohatohahia.
(7) Ko te injector wahie paerewa kua tohua e te pae whakamatautau ka taea te whakamahi ki te tuku hinu kia kaua e neke atu i te 300 mm3 mo ia huringa. A, no te te tere o te papu werohanga wahie ko 1000 r / min, te rakau taputapu supply hinu kua whakaritea i te tūranga o 103 mm3 huringa. 1000 wa te papu Ina ko te rōrahi hinu i roto i te whānuitanga o 102-103 cm3, ko te 17.5 MPa te pehanga whakatuwhera o te ngira.
(8) Mo te papu werohanga wahie e whakamahia ana, na te iti o te kounga o te whakamahinga, me whakamahi te injector wahie kua oti te whakatika o te waka taketake mo te whakamatautau papu werohanga wahie. Ma tenei ara, ka taea te whakamana i te miihini ki te mahi i raro i te tuku hinu noa me te riterite mai i te tiimatanga tae noa ki te whakakapi i te huihuinga injector wahie. Mena ka whakamahia he injector wahie paerewa mo te patuiro, a ka mahi te miihini me te injector wahie kore-paerewa, kaore e taea te mahi me te riterite e hiahiatia ana o te tuku wahie, na reira ka ngaro te hiranga o te patuira o te papu werohanga wahie.
(9) Ko te pāmahana o te ruma whakamatautau he nui te awe ki te tuku wahie o te papu werohanga wahie, na te mea ka rereke te tohu o te hinu diesel ki te pāmahana, me te tuku wahie paerewa kua tohua i roto i nga tuhinga hangarau e pa ana ki te pāmahana rūma paerewa. o 20 ℃. Te tuku wahie. I whakamatauhia e te whakamatautau ka heke te pāmahana mai i te 40°C ki te 6°C, ka piki ake te tuku wahie ma te 20% ki te 40%, a ki te whakahekehia ano te pāmahana, ko te aukati o te paipa hinu pehanga teitei me te injector. ka tino piki ake na te nui o te pikinga o te hinu diesel, ka heke iho te tuku wahie. Hei whakatika tika i te tuku wahie, me pupuri te pāmahana o te awheawhe whakamatautau i roto i te awhe noa o te pāmahana o te 15-20 ° C, ina koa he nui ake te awangawanga o te papu wero wahie tere-tere ki te huringa o te pāmahana wahie.
