Kutentha kwamagetsi pafupipafupi msonkhano wotentha komanso kutsitsa kotentha kwa mphete yamkati

Mphete yamkati ya bere imakhala ndi manja pamtengowo, ndipo mphete yamkati ndi shaft zimagwirizanitsidwa pamodzi ndi kusokoneza kokwanira kwa shaft ku dzenje. Mphete yamkati imakula pambuyo pa kutentha, kotero kuti ikhoza kuikidwa mosavuta pamtengowo. Pambuyo kuziziritsa, kutsinde kumangirizidwa. Pambuyo pa nthawi inayake yogwiritsira ntchito, mphete yamkati yatha ndipo iyenera kusinthidwa. M’mbuyomu, chokoka chinali kukoka mphete yamkati kuchokera ku shaft, yomwe imasokoneza pamwamba pa shaft. Ngati mphete yamkati pa shaft ikhoza kutenthedwa mofulumira, m’mimba mwake ya shaft sichidzakula kapena kukhala yaikulu kwambiri chifukwa cha kufalikira kwa mphete yamkati. Ndi kuwonjezeka kochepa, mphete yamkati imatha kuchotsedwa pamtengo. Uku ndiko kutchedwa thermal unloading. Pamwamba pa shaft sichidzagwedezeka, ndipo ikhoza kugwiritsidwanso ntchito popanda kukonzanso.

Mphete yamkati ya ma axle a njanji ikuwonetsedwa pazithunzi 12-62. Zili ndi mphete ziwiri, zomwe zimayikidwa imodzi ndi imodzi pamene shaft imayikidwa, ndipo mphete ziwirizo zimachotsedwa nthawi imodzi pamene zimachotsedwa pamtengowo. Unyinji wa mphete ziwiri zamkati ndi 3.54kg ndi 2.77kg motsatana, ndipo kutentha kwa kutentha kwapang’onopang’ono ndikutsitsa kotentha kumafunika kukhala 130Y.

Mphete yamkati yonyamula imatha kutenthedwa pamtengo bola ngati kutentha kumafika 130 ° C. Ponena za kutalika kwa nthawi yotentha

Chithunzi 12-62 Kukhala ndi mphete yamkati

Zilibe kanthu, koma kuchotsa mphete yamkati kuchokera ku shaft thermally, kutalika kwa nthawi ndi kutentha kwafupipafupi kutenthetsa magetsi ndikofunikira kwambiri. Ngati nthawi yotentha ndi yaitali, shaft idzawotchanso, ndipo zidzakhala zovuta kuchotsa mphete yamkati ya kubala. Chithunzi 12-63 chikuwonetsa ubale womwe ulipo pakati pa kukhala ndi mainchesi amkati ndi nthawi yotenthetsera yotenthetsera, yomwe ingagwiritsidwe ntchito ngati kalozera posankha nthawi yotenthetsera yotenthetsera pakuwerengera mapangidwe..

Chithunzi 12-63 Kutentha nthawi yotsitsa matenthedwe okhala ndi mphete yamkati

Chithunzi 12-64 chikuwonetsa zida zotenthetsera ma frequency otenthetsera pakuwotchera ndi kutulutsa kutentha kwa mphete yamkati. Mbali yakumanzere ya chithunzicho ndi inductor yamagetsi pafupipafupi, ndipo kumanja ndi kabati yowongolera magetsi. The koyilo ya mphamvu pafupipafupi inductor amapangidwa ndi 3.28mm X 8.6mm koyera mkuwa waya. M’mimba mwake wa coil ndi 74mm. Kunja kwa koyiloyo, pali ma seti 12 a ma conductor maginito okhala ndi ma sheet achitsulo a silicon. Mapeto awiriwa amangiriridwa ndi mbale zachitsulo ndikusonkhanitsidwa pampando. Mpandowo uli ndi zodzigudubuza 4 kuti zisunthire mphete yamkati kuchoka pa shaft panthawi yotsitsa kutentha. Kabati yoyang’anira magetsi imakhala ndi nyali zowunikira, ma relay a nthawi ndi AC contactor, ndi zina zotero, zomwe zimagwiritsidwa ntchito poyang’anira nthawi yamagetsi ndi mphamvu ya inductor. Pamene mphamvu pafupipafupi inductor ikugwira ntchito, voteji ndi 380V, panopa ndi 88A, ndipo mphamvu ndi 21kW. Mphete yamkati yonyamula imatha kutenthedwa kwa 30s mpaka 130Y, ndipo mphete yamkati yonyamula imatha kuchotsedwa pamtengo.
