Ma injini achikhalidwe alinso ndi mabwalo amadzi ozizira, koma mabwalo amadzi ozizira a magalimoto amagetsi atsopano ndi osiyana kwambiri.Mutuwu ukuyang'ana momwe madzi ozizira amachitira ndi ma actuators osiyanasiyana ndi masensa pa magalimoto atsopano amphamvu.
Pampu yamadzi yamagetsi
Kuti choziziritsa kuzizirirapo chiziyenda munjira iliyonse yozizirira, ndithudi mpope imafunika.Injini imayendetsa pampu yamadzi yamakina chifukwa cha kuzungulira kwa shaft ya injini.M'magalimoto oyera amagetsi ndi magalimoto osakanizidwa, chifukwa cha kufalikira kwa zofunikira zoziziritsa komanso kuthamanga kwa shaft yamoto, mapampu amadzi amagetsi amagwiritsidwa ntchito kukwaniritsa zofunikira zowongolera kutentha.
Gawo la hydraulic la pampu yamadzi yamagetsi silosiyana kwambiri ndi mpope wamadzi wamakina.Kusiyana kwakukulu kuli mu gawo lamagetsi lamagetsi la pampu yamagetsi yamagetsi.Kuzungulira kwa pampu yamadzi yamagetsi kumaperekedwa ndi brushless DC mota.Mphamvu yamagalimoto imachokera ku 30W mpaka 150W, yomwe imatha kuphimba mitundu yambiri yamagetsi komanso yosakanizidwa komanso kasamalidwe ka matenthedwe, kupatula kuti mafuta opangira mafuta adzagwiritsa ntchito mpope wamadzi wa 200W ndi kupitilira apo..Palinso mapampu amadzi omwe amagwiritsa ntchito ma motors opukutidwa, koma tikulimbikitsidwa kugwiritsa ntchito ma motors opanda brush, omwe amakhala ndi moyo wautali komanso phokoso lochepa.
Kuphatikiza pa DC brushless motor pump drive, mabwalo ena amatha kuwonjezedwa ku PCB yosindikizidwa ya board yaPampu yamadzi yamagetsi ya EVmalinga ndi zofunikira zogwirira ntchito.Pampu yamadzi yamagetsi imatha kugwiritsa ntchito PWM control kapena LIN bus control (palinso CAN bus control).
Mapampu amadzi amagetsi oyendetsedwa ndi LIN amalimbikitsidwa pamagalimoto amagetsi oyera, chifukwa nthawi zambiri pamakhala mapampu amadzi ambiri ndi ma valve amadzi omwe amagwiritsidwa ntchito popanga matenthedwe oyendetsa magalimoto amagetsi oyera.Ngati pampu iliyonse yamadzi ndi valavu yamadzi imagwiritsa ntchito mphamvu ya PWM, woyang'anira kutentha ayenera kupereka IO Yosiyana ya mapampu ndi ma valve.Basi ya LIN ndi yokwanira kukweza mapampu onse amadzi ndi ma valve amadzi omwe amagwiritsidwa ntchito pamagalimoto amagetsi amagetsi (LIN ikhoza kulumikizidwa ku node 16).
Malinga ndi malo a chitsanzo, wanzeruMapampu Ozizirira Magalimoto a Dcndi ma valve amadzi amagetsi amathanso kuganiziridwa.Mwachitsanzo, pamitundu yapakatikati mpaka-mapeto, kugwiritsa ntchito makina owongolera matenthedwe anzeru kungathenso kulemeretsa ntchito izi: chenjezo la volt overvoltage/undervoltage, chenjezo lotenthetsera la PCB, kuyang'anira pampu yamadzi, chenjezo lodzaza pampu yamadzi, kuzindikira kwapampu yamadzi. , etc. Kuphatikizana ndi ntchito ya intaneti ya Magalimoto, imathanso kuyang'anira zigawo za kayendedwe ka kutentha mumtambo mu nthawi yeniyeni kuti ikwaniritse ntchito zenizeni zapamwamba monga kufufuza zolakwika, kulosera zolephera, ndi kusanthula moyo.
