Ma injini akale alinso ndi ma circuit amadzi ozizira, koma ma circuit amadzi ozizira a magalimoto atsopano amphamvu ndi osiyana kwambiri. Mutu uno ukuwonetsa momwe madzi ozizira amagwirira ntchito ndi ma actuator osiyanasiyana ndi masensa pa magalimoto atsopano amphamvu.
Pampu yamadzi yamagetsi
Kuti choziziritsira chiziyenda bwino mu dera lililonse loziziritsira, ndithudi pamafunika pampu. Injini imayendetsa pampu yamadzi yamakina chifukwa cha kuzungulira kwa shaft ya injini. Mu magalimoto amagetsi enieni ndi magalimoto osakanikirana, chifukwa cha kusakanikirana kwa zofunikira zoziziritsira ndi liwiro la shaft ya mota, mapampu amadzi amagetsi amagwiritsidwa ntchito kukwaniritsa zofunikira zowongolera kutentha.
Gawo la hydraulic la pampu yamagetsi silisiyana kwambiri ndi pampu yamagetsi yamadzi. Kusiyana kwakukulu kuli mu gawo lamagetsi loyendetsa pampu yamagetsi. Kuzungulira kwa pampu yamagetsi yamagetsi kumaperekedwa ndi mota ya DC yopanda burashi. Mphamvu ya mota imayambira pa 30W mpaka 150W, yomwe imatha kuphimba mitundu yambiri yamagetsi ndi yosakanikirana komanso kapangidwe ka kayendetsedwe ka kutentha, kupatula kuti stack yamafuta imagwiritsa ntchito pampu yamadzi ya 200W ndi kupitirira apo. Palinso mapampu ena amadzi omwe amagwiritsa ntchito ma mota opukutidwa, koma tikukulimbikitsani kugwiritsa ntchito ma mota opanda burashi, omwe amakhala ndi moyo wautali komanso phokoso lochepa.
Kuwonjezera pa DC brushless motor pump drive, ma circuit ena akhoza kuwonjezeredwa ku PCB printed circuit board yaPampu yamadzi yamagetsi yamagetsimalinga ndi zofunikira pa ntchito. Pampu yamadzi yamagetsi imatha kugwiritsa ntchito PWM control kapena LIN bus control (palinso CAN bus control).
Mapampu amadzi amagetsi olamulidwa ndi LIN amalimbikitsidwa pamagalimoto amagetsi okhaokha, chifukwa nthawi zambiri pamakhala mapampu ambiri amadzi ndi ma valve amadzi omwe amagwiritsidwa ntchito popanga makina oyendetsera kutentha kwa magalimoto amagetsi okhaokha. Ngati pampu iliyonse yamadzi ndi valavu yamadzi imagwiritsa ntchito PWM control, chowongolera kutentha chimayenera kupereka IO Yosiyana ya mapampu ndi ma valve. Basi la LIN ndi lokwanira kuyika mapampu onse amadzi ndi ma valve amadzi omwe amagwiritsidwa ntchito m'magalimoto amagetsi okhaokha (LIN ikhoza kulumikizidwa ku ma node 16).
Malinga ndi malo a chitsanzocho, wanzeruMapampu Oziziritsa a Dc a Magalimotondi ma valve amagetsi amagetsi angaganiziridwenso. Mwachitsanzo, pa mitundu yapakati mpaka yapamwamba, kugwiritsa ntchito ma actuator anzeru oyendetsera kutentha kungathandizenso ntchito izi: chenjezo la overvoltage/undervoltage, chenjezo la PCB overheating, kuyang'anira malo osungira madzi, chenjezo la overload pampu yamadzi, kuzindikira kulephera kwa pampu yamadzi, ndi zina zotero. Kuphatikiza ndi ntchito ya intaneti ya Magalimoto, imathanso kuyang'anira zigawo za makina oyendetsera kutentha mumtambo nthawi yeniyeni kuti ikwaniritse ntchito zapadera monga kuzindikira zolakwika, kulosera kulephera, ndi kusanthula moyo.
