ZQYM-8320 Yakajairwa Rail Diesel Fuel vp44 Injection Pump Test Bhenji HEUI jekiseni Yekuyedza Equipment pombi tester simulator

Diesel injini kuita kunoenderana zvakanyanya nekugadziriswa chaiko kwepombi jekiseni remafuta. Kunyangwe iyo mafuta jekiseni pombi yekuyedza bhenji ine yakasimba tekinoroji zvinodiwa kuti ive nechokwadi chekurongeka kwemafuta jekiseni pombi paramita gadziriso, kana kushandiswa uye kugadzirisa kukasaitwa nemazvo, kunaka kwekugadziriswa kwepombi jekiseni remafuta hakugone kuvimbiswa.

1 Zvido zvehunyanzvi zvemafuta jekiseni pombi yekuyedza bhenji
(1) Chikanganiso chechiyero chebhenji rekuedza hachifanirwe kudarika ± 10' pane chero chinzvimbo, uye chiyero chinofanira kujeka.
(2) Iko kushanduka kwekukurumidza kwekukurumidza mukati mekuchinja kwega kwega kwechigadziro chekubuda kwebhenji rekuedza hakufaniri kudarika 1% yezinga rekuedzwa apo kuyerwa kwekuyerwa kwekubuda shaft transmission disc iri> 600 r / min; kana kukurumidza kuri ≤ 600 r/min, kushanduka kwekukurumidza kwekukurumidza hakuzopfuuri 6 r/min.
(3) Nzira yekuverenga yebhenji rekuedza inofanira kuva yakarurama uye inonzwisisika, uye inogona kuverenga 100 kusvika ku1000 nguva mugiya rega rega, uye kukanganisa kunobvumirwa kuverenga kwehurongwa hwose inguva imwe.
(4) Silinda yekuyeresa oiri yebhenji rekuyedza inofanira kuva nechiyero chakajeka uye chakarurama, chiyero chidiki hachifanirwe kunge chakakura kupfuura 1% yechiyero chakazara, uye kukanganisa kwechiyero kunofanira kunge kuri mukati me0.5% yechiyero chakazara.
(5) Mafuta ekupa kumanikidza kwebhenji rekuyedza kunofanirwa kuchinjika uye kuchengetwa yakatsiga. Payero yakarongedzerwa, kana maburi ese akavharwa, iyo yakanyanya kudzvanywa inofanirwa kusvika: yakaderera-inodzvinyirira mafuta dunhu ≥ 0.4 MPa; high-pressure oil circuit ≥ 34 MPa.
(6) Maparamendi epombi yehutsi-yepamusoro-yekukonzeresa iyo in-line mafuta jekiseni pombi: kureba × yekunze dhayamita × yemukati dhayamita, iyo 600 mm × 6 mm × 2 mm inoshandiswa kugadzirisa pombi jekiseni remafuta rine mafuta anotenderera. kugovera vhoriyamu hakupfuuri 300 mm 3; 800 mm × 8 mm × 39 mm inoshandiswa pakumisikidzwa kwepombi jekiseni remafuta nemafuta anotenderera anodarika 300 mm; 800 mm × 6 mm × 2 mm inoshandiswa pakumisikidza kweakaparadzirwa mafuta jekiseni pombi.
(7) Iyo yakajairwa jekiseni remafuta rakasarudzwa nebhenji rekuyedza rinogona kushandiswa kupa mafuta asingapfuuri 300 mm3 kutenderera. Kana kumhanya kwepombi yejekiseni yemafuta iri 1000 r/min, iyo mafuta ekugovera giya tsvimbo inogadziriswa panzvimbo ye103 mm3 kutenderera. 1000 nguva yepombi Kana huwandu hwemafuta huri pakati pe 102-103 cm3, kuvhurika kwevhavha yetsono ndeye 17.5 MPa.
(8) Yepombi yejekiseni yemafuta iri kushandiswa, nekuda kwekudzikisira kwemhando yekushandiswa, iyo yakagadziridzwa jekiseni yemafuta yemotokari yepakutanga inofanira kushandiswa pabvunzo yepombi jekiseni. Nenzira iyi, injini inogona kuvimbiswa kushanda pasi pezvakajairwa uye yunifomu mafuta ekupa kubva pakutanga kusvika iyo jekiseni yemafuta inotsiviwa. Kana jekiseni remafuta rakajairwa richishandiswa kugadzirisa, uye injini ichishanda neasina-standard mafuta jekiseni, haigone kushanda neinodiwa yakafanana yekupihwa kwemafuta, nokudaro kurasikirwa nekukosha kwemafuta jekiseni pombi debugging.
(9) Tembiricha yekamuri yekuyedza ine simba guru pakupihwa kwemafuta epombi jekiseni remafuta, nekuti dhigirii remafuta edhiziri rinoshanduka nekudziya, uye chiyero chemafuta chinotsanangurwa mumagwaro ehunyanzvi chinoreva tembiricha yekamuri. ye20 ℃. Mafuta ekupa. Muedzo wakaratidza kuti kana tembiricha inodonha kubva pa40 ° C kusvika 6 ° C, mafuta ekufambisa anogona kuwedzera ne20% kusvika 40%, uye kana tembiricha yakadzikiswa, kupokana kwepombi yemafuta ekumanikidza uye jekiseni. ichawedzera zvakanyanya nekuda kwekuwedzera kukuru kwedhigirii mafuta edhiziri, mafuta emafuta achadzikira panzvimbo. Kuti ugadzirise mafuta anowanikwa nenzira kwayo, kutonhora kwemusangano wekuedza kunofanira kuchengetwa munzvimbo yakajairika yekushisa kwe 15-20 ° C, kunyanya iyo yepamusoro-speed jekiseni pombi inonyanya kunzwisiswa nekuchinja kwekushisa kwemafuta.
