Remubatanidzwa - inodzivirira yakavimbika midziyo kubva runyararo utsinye

In magetsi engineering, isu kazhinji nokusangana rokuti "akakura". Chii? Remubatanidzwa - haisi insulating remubatanidzwa kuti panguva kushandiswa imvura, uye ipapo akarapa harisi kwayo sezvamunoita zvokufembedzwa. Mukomboni havazotadzi ehupfumi ayo ari tembiricha siyana kubva -50 kusvika +200 Celsius, ndiyo husingakwanisi nemwaranzi nokuda impregnation, achidurura nodes, redhiyo zvikamu, zvemagetsi kudzivirira akadhindwa redunhu mapuranga uye zvinoriumba yavo Kufurirwa nevamwe (zvemaziso, chafariz, mushonga, vibration), kunyanya munharaunda utsinye. Pashure pezvose, mamiriro ezvinhu pasi izvo kuti ishande yemagetsi uye zvemagetsi uye mano apparatuses vari kure murabhoritari. Izvi tembiricha yakaderera kubva Far North, uye yakakwirira mwando inopisa okunze, uye utsinye hwaiitwa nzvimbo, uye zvichingodaro. D. vose pamusoro ari kumanikidza zvakagadzirwa mainjiniya kudzivirira kushandisa imwe ndima ine mwando dzinga coatings chakawedzerwa zvokuvakisa potting uye encapsulation zvinoriumba uye michina. Most inowanzoshandiswa nokuda ichi chinangwa maviri-chikamu wemisanganiswa.

Pakazosvika ehupfumi ose yeimwe akakamurwa:

- impregnation;

- magetsi;

- Kudzingwa;

- kwakavharwa nenyama;

- plasticized rabha;

- kamari samolecular uremu plasticizer.

Impregnating remubatanidzwa - remubatanidzwa rinoshandiswa kuti impregnation pamusoro windings ose Motors uye michina.

Insulating, akavapindurawo, akakamurwa:

- thermoset (asingadi kunyevenutsa pashure achirapa). Izvi zvinosanganisira epoxy, polyester nezvimwe Inogadzirwa nemasiridzi anobuda mumiti;

- thermoplastic (ngoni kudziyisa) - bitumens waxy dielectrics, thermoplastic Polymers (polystyrene, polyisobutylene).

Kuzadza remubatanidzwa - a sezvamunoita kuti ichizadza in mabhokisi waya, uyewo Simbiso mune dzemagetsi michina uye namano.

Insulating muvhenganiswa yaigadzirwa methacrylic esters, anoshandiswa sezvo zvose impregnation uye kuraswa. yeimwe kwakadaro pashure achirapa ari kudziya 70-100 Celsius (uchinyanya hardener, pachikumbaridzo iri akatura 20 madhigirii), vari thermosetting uye zvinogona kushandiswa pane tembiricha -55 kusvika +105 inegumi. Vari akashandiswa impregnation pamusoro-siyana kutenderera midziyo (uye coils ichitenderera Motors uye said.) Ndezvipi anopa kunobudirira kudzivirira electrocution.

Potting remubatanidzwa kwakavakirwa bhitumini nenhanho kupisa nemishonga (105 ° C) ndowenyika kirasi "A". Rine inonyanya kupisa nemishonga epoxy uye silicone yeimwe.

Kwakavharwa nenyama plasticized rabha wemisanganiswa vakawana kunyanya kushanda. Nhasi kwakakurumbira chaizvo remubatanidzwa kuti siyana. Nekuti chinoitwa kusanduka silicone achitanga kubva configurations siyana. The tembiricha hurumende mukomboni zvasvika kuguma + 200 ° C, zviri nenharo pamusoro 250 ° C haana yakarumbidza nokuti polymer rinoparadzwa linkages.

Pari inobereka mamakisi siyana yeimwe, chimwe nechimwe awana kukura kwayo uye ane zvivako zvakafanana nayo.

Most mukurumbira akava epoxy remubatanidzwa - mumwe polymer pamwe yakaderera shrinkage, chakanakisisa dielectric unhu uye yakakwirira adhesion. It anogona kushanda mumamiriro ezvinhu ose deformation zvachose. Epoxy Inogadzirwa nemasiridzi anobuda mumiti vari zvinowanzoshandiswa siyana zvokushandisa, zvivako, zvivako. wemisanganiswa ava nezvinotaurwa nevamwe oligomers uye mhanyisa nokuomesa kwavo nokusanganisa nevamwe yeimwe. The drawback pamusoro epoxy nebwe riri pasi uchishandisa tembiricha, izvo haikwani kurishandisa mune imwe nzira kuti inoshanda asi utsinye mamiriro.

Nokupfupikisa, tinogona kutaura kuti kushandiswa yeimwe kunowedzera operative rakavimbika uye kunosvika upenyu basa zvigadzirwa uye mano magetsi, dzinovimbisa chisimbiso chavo uye kudzivirira vibration, kunobatsira kudzivirira vatengi kubvira Magetsi.
