Chipangizo cha jenereta yamagalimoto ndi mfundo yogwirira ntchito

Jenereta ndi gawo lofunikira la chipangizo cha galimoto iliyonse. Ntchito yaikulu ya unit iyi ndi kupanga magetsi kuti apereke dongosolo lonse la galimoto ndikuwonjezera batire. Mphamvu yozungulira ya crankshaft imasinthidwa kukhala magetsi.

Jenereta imagwirizanitsidwa ndi crankshaft pogwiritsa ntchito lamba - lamba la jenereta. Zimayikidwa pa pulley ya crankshaft ndi pulley ya jenereta, ndipo injini ikangoyamba ndi ma pistoni akuyamba kusuntha, kayendetsedwe kameneka kamasamutsidwa ku pulley ya jenereta ndipo imayamba kupanga magetsi.

Kodi panopa amapangidwa bwanji? Chilichonse ndi chophweka, mbali zazikulu za jenereta ndi stator ndi rotor - rotor imazungulira, stator ndi gawo lokhazikika lokhazikika ku mkati mwa jenereta. Rotor imatchedwanso zida za jenereta, imakhala ndi shaft yomwe imalowa mu chivundikiro cha jenereta ndikumangirizidwa ndi chonyamulira, kuti shaft isatenthedwe panthawi yozungulira. Kunyamula shaft jenereta kumalephera pakapita nthawi, ndipo izi ndizovuta kwambiri, ziyenera kusinthidwa munthawi yake, apo ayi jenereta iyenera kusinthidwa kwathunthu.

Chothandizira chimodzi kapena ziwiri zimayikidwa pamtengo wa rotor, pakati pawo pali mafunde osangalatsa. The stator imakhalanso ndi mapiringidzo ndi zitsulo mbale - stator pachimake. Chipangizo cha zinthu izi chikhoza kukhala chosiyana, koma maonekedwe a rotor angafanane ndi silinda yaing'ono yomwe imayikidwa pa chodzigudubuza; pansi pa mbale zake zachitsulo pali zozungulira zingapo zozungulira.

Pamene inu kutembenukira kiyi mu poyatsira lophimba theka kutembenukira, voteji umagwiritsidwa ntchito kwa rotor makhotakhota, izo zimafalitsidwa kwa ozungulira kudzera maburashi jenereta ndi kuzembera mphete - yaing'ono zitsulo bushings pa ozungulira kutsinde.

Zotsatira zake ndi mphamvu ya maginito. Pamene kutembenuka kuchokera ku crankshaft kumayamba kufalikira ku rotor, magetsi osinthika amawonekera mumayendedwe a stator.

Mpweyawu siwokhazikika, matalikidwe ake akusintha nthawi zonse, choncho amafunika kufananizidwa molingana. Izi zimachitika pogwiritsa ntchito rectifier unit - ma diode angapo omwe amalumikizidwa ndi mafunde a stator. Udindo wofunikira umaseweredwa ndi voteji regulator, ntchito yake ndi kusunga voteji pa mlingo wokhazikika, koma ngati iyamba kuwonjezeka, ndiye kuti mbali yake imasamutsidwa kubwerera ku mphepo.

Majenereta amakono amagwiritsa ntchito mabwalo ovuta kuti ma voltage apitirire nthawi zonse. Kuphatikiza apo, zofunikira zoyambira jenereta zimayikidwanso:

• kusunga machitidwe okhazikika a machitidwe onse;
• mtengo wa batri ngakhale pa liwiro lotsika;
• kusunga magetsi mkati mwa mulingo wofunikira.

Ndiko kuti, tikuwona kuti ngakhale chiwembu cham'badwo wamakono sichinasinthe - mfundo ya kulowetsedwa kwa electromagnetic imagwiritsidwa ntchito - koma zofunikira za khalidwe lamakono zawonjezeka kuti zikhalebe ndi ntchito yokhazikika ya maukonde pa bolodi ndi ogula ambiri magetsi. Izi zidatheka chifukwa chogwiritsa ntchito ma conductor atsopano, ma diode, mayunitsi owongolera, komanso kukonza njira zolumikizirana zapamwamba kwambiri.

Kanema wa chipangizocho ndi mfundo yoyendetsera jenereta
