1.Basa rekunyudza pendi

1. Kuvandudza hunyoro-uchapupu hwekushanda kwemotor windings.

Mumhepo inoputika, pane zvakawanda zvepores mu slot insulation, interlayer insulation, phase insulation, kusunga waya, etc.Zviri nyore kutora unyoro mumhepo uye kuderedza kushanda kwayo kwekudzivirira. Mushure mekunyura nekuomeswa, mota inozadzwa nependi inodzivirira uye inoita firimu rependi rakatsetseka, izvo zvinoita kuti zviome kuti hunyoro uye magasi anoparadza apinde, nekudaro kuwedzera hunyoro-huchapupu uye husingadziviriri zvimiro zvemhepo.

2.Enhance magetsi ekudzivirira simba remhepo.

Mushure mokunge mamhepo akanyikwa mupende uye akaomeswa, kutendeuka kwavo, makoiri, zvikamu uye zvakasiyana-siyana zvekudzivirira zvinhu zvakazadzwa nependi yekudzivirira ine yakanaka dielectric properties, zvichiita kuti simba rekudzivirira remhepo rive rakakwirira kudarika risati ranyura mupende.

3.Improved kupisa kupisa mamiriro uye kuwedzerwa kupisa conductivity.

Kukwira kwekushisa kwemota panguva yekushanda kwenguva refu kunobata zvakananga hupenyu hwayo hwebasa. Kupisa kwemhepo kunotamirwa kune inopisa sink kuburikidza neslot insulation. Iwo mapeji makuru pakati pepepa rekuvhara waya pamberi pevarnishing haakodzeri kuitisa kwekupisa mumhepo. Mushure mekugadzira varnish uye kuomeswa, mapeji aya anozadzwa ne insulating varnish. Iyo yekupisa conductivity ye insulating varnish iri nani kupfuura iyo yemhepo, nokudaro inovandudza zvakanyanya mamiriro ekupisa kupisa kwemhepo.

2.Types of insulating varnish

Kune marudzi akawanda e insulating pendi，Senge epoxy polyester, polyurethane, uye polyimide.Kazhinji, inopindirana insulating pendi inosarudzwa zvichienderana nekupisa kwekupisa, senge 162 epoxy ester tsvuku enamel giredhi B (130 madhigirii) 9129 epoxy solvent-isina topcoat F (155 dhigirii purified 0), polyating U1 dhigirii reSilicone), polyating U1970, polyester, 197 dhigirii iyo mamiriro ekuti pendi inodzivirira inosangana nezvinodiwa zvekupisa kupisa, inofanirwa kusarudzwa zvinoenderana nenharaunda iyo mota iripo, senge thermal conductivity, hunyoro kuramba, nezvimwe.

3.Marudzi mashanu ekugadzira varnishing

1.Kudira

Paunenge uchigadzirisa motokari imwe chete, iyo inoputika varnishing inogona kuitwa nekudururira. Paunenge uchidurura, isa stator vertically pane pende inodonha tireyi ine imwe mugumo wemhepo yakatarisa kumusoro, uye shandisa poto yepende kana bhurashi repende kuti udururire pende pamucheto wepamusoro wemhepo. yakadirwa zvizere.

2.Drip leaching

Iyi nzira inokodzera varnishing yemagetsi madiki uye epakati-kati.

①Formula. 6101 epoxy resin (reshiyo yakawanda), 50% tung oiri maleic anhydride, yakagadzirira kushandiswa.

②Preheating: Pisa inomonereka kwemaminetsi angangoita 4, uye dzora tembiricha iri pakati pe100 ne115°C (inoyerwa nethermometer yenzvimbo), kana kuisa mhepo muchoto chekuomesa uye kupisa kwemaawa angangoita 0.5.

③Drip. Isa mota stator yakatwasuka patirayi yependi, uye tanga kudonha pendi nemaoko kana tembiricha yemota yadonha kusvika 60-70 ℃. Mushure memaminitsi gumi, shandura stator uye udonhe pende kune imwe mugumo wemhepo kusvikira yanyatsonyorova.

④Kuporesa. Mushure mekudonha, mhepo inoputika inosimbiswa kuporesa, uye kutonhora kwemhepo kunochengetwa pa 100-150 ° C; kukosha kwekudzivirira kwekudzivirira kunoyerwa kusvika kwave kwakakodzera (20MΩ), kana mhepo inoputika inoiswa muchoto chekuomesera chekupisa pakupisa kwakafanana kwemaawa maviri (zvichienderana nekukura kwemotokari), uye inotorwa kunze kwechoto kana kudzivirira kwekudzivirira kunodarika 1.5MΩ.

3.Roller pendi

Iyi nzira yakakodzera kune varnishing yepakati-saizi mota. Paunenge uchitenderedza pendi, dururira pendi inodzivirira mutangi repende, isa rotor mutangi repende, uye pendi yependi inofanirwa kunyudza iyo rotor inotenderera kweanopfuura 200mm. Kana tangi yepende yakanyanyisa kudzika uye nzvimbo ye rotor inoputika yakanyudzwa mupende idiki, rotor inofanira kupetwa kakawanda, kana pende inofanira kuiswa nebhurashi apo rotor yakakungurutswa. Kazhinji kutenderedza 3 kusvika ku5 nguva kunogona kuita kuti insulating pendi ipinde mukati mekuvhara.

4.Kunyudzwa

Paunenge uchigadzirisa madiki uye epakati-saizi motors mumabheti, iyo windings inogona kunyudzwa mupende. Paunenge uchinyudza, tanga waisa pendi yakaringana yependi mugaba, wozoturika mota stator mukati, kuitira kuti mvura yependi inonyudza stator neinopfuura 200mm. Kana iyo pendi yemvura inopinda mukati mezvimedu zvose pakati pemhepo uye pepa rekudzivirira, stator inosimudzwa uye pende inodonhedzwa. Kana 0.3 ~ 0.5MPa kudzvanywa kuchiwedzerwa panguva yekunyudzwa, mhedzisiro ichava nani.

5.Vacuum pressure immersion

Iwo ma windings eakakwira-voltage mota uye madiki uye epakati-saizi motors ane yakakwirira insulation mhando zvinodiwa anogona kuiswa pasi vacuum pressure dipping. Panguva yekunyura, stator yemota inoiswa mumudziyo wakavharwa pendi uye hunyoro hunobviswa uchishandisa vacuum tekinoroji. Mushure mekunge mahwindi akanyikwa mupende, kudzvanywa kwe200 kusvika 700 kPa kunoshandiswa kune pendi pendi kubvumira mvura yependi kuti ipinde mukati mezvimedu zvese mumhepo uye yakadzika mumapores epa insulating bepa kuti ive nechokwadi chekunyura.
