Welding hwemhangura waya: kudzokorora nzira uye michina. Pokunamatidza kana nomoto kuti waya mhangura - inova nani?

Huru basa kana iwe batanidza chimwe zvemagetsi iriyo kuitira zvavo nemutengo nemishonga. Kana murombo kuonana kuramba pakati waya yemhangura zviri nani, zvichiguma kudziyisa waya. Pane nzira dzakawanda kuonana kubatana, asi zvikuru hwakavimbika uye inobudirira runoonekwa kuti welded mhangura waya. Michina iyi ambotirega monolithically batanidza zvose waya tambo, nokudaro kuwana yakadereresa zvinogoneka magetsi nemishonga. Somugumisiro yacho kudziyisa waya panobviswa, saka yekudyidzana zvakawedzera pamwero moto vakachengeteka.

Nzira maererano waya

Copper ndiyo huru kondakita zvinhu. Nemhaka physico-zvemakemikari ehupfumi iyi zvinhu (yakakwirira ductility, kushaya elasticity), kushanda navo ine maitiro ayo. Electrical midziyo mitemo vanoti mashandiro ari kubatana bazi uye okontsovyvaniyu mutsinga kuti netambo uye waya vanogona anoitwa pokunamatidza nomoto, crimping kana kudzvinya (bhaudhi, sikuruu, etc.). Mumwe nomumwe wavo ane pachake zvachiri, izvo dzichakurukurwa pazasi.

Remubatanidzwa waya kubudikidza stranding

A nyore monyorora pamusoro waya chinorambidzwa Pue, sezvazvakaita kupfuura va neudhadha, pfupi uye moto chokuita. Pasinei neizvi, zvipfuwo nemhizha uye handiregi kushandisa nzira iyi, kunyange zvazvo migumisiro ichi "raanoziva" zvinogona plavchevnymi chaizvo.

Achitsaudzira waya ane nemhinganidzo yakakura: kwokubatana emhangura pakupedzisira akaremara uye simba, pakupedzisira kuparadzwa zvachose nokuda mukuru kuchinja nemishonga.

Zvinofanira kurangarirwa kuti nokuvhiringidza nzira ingashandiswa chete kunoshamisa nguva kana yaida kuti adzorere nemagetsi uye nedzimwe nzira imwe ezvinhu havana kuwanikwa. Zvakakosha chaizvo kuti kutora hanya unhu, kuchengeteka uye rakavimbika papi.

Zvinonzi zvaisambobvumirwa:

• Unobva waya aumba kubva dzakasiyana zvinhu (aruminiyamu uye mhangura);
• Unobatanidza hwakasimba mhangura waya ane multifilamentary.

Stranding muitiro uri sezvinotevera:

1. Clear waya kuputira kubva chinhambwe 6-8 masendimita kubva kumucheto;
2. Shandisa imwe waya kune vamwe uye crosswise maximally batana ruka. Kana chikamu muchinjikwa pemhangura waya anopfuura 1 ba. neMM, kuvhiyiwa rinoitwa pamwe pingisi.
3. Kuruma kumuromo kwematanda forceps asara waya.
4. Nokuvhiringidza insulated kushandisa chaiyo insulating zvinhu (PVC, kana kupisa vanodzokera sepombi, nguwani) kana akaturikidzana vanoverengeka insulating tepi. Insulation anofanira hako andobata insulating rukoko waya.

kumanikidzwa bvunzo

The kwacho inofanira unobva waya kuburikidza ravo rinokosha crimping munhu tubular ruoko kana muromo. mano aya anoshandiswa, kana chikamu muchinjikwa pemhangura waya ndiyo 2,5-240 ba. mm. Zvazvisingarambiki zvakanakira crimp michina vari kumhanya uye rakarurama basa, uyewo haizopereri mukurumari uye vakachengeteka kubatana.

Nokuti crimping kushandisa chaiyo chokushandisa - zvemaziso, hydraulic kana nemagetsi pingisi kana nyanzvi obzhimochnye wokudhinda. Vakasarudzwa casings anofanira inobva uwandu zvikamu uye zvakabatana ne waya.

Mushure nokutorera uye kuchenesa zvipenyu, ivo anechekuita Goldstone-vaseline namatidza, kupfeka ruoko uye kubereka crimp. Compression dzisimbe dzoga.

Crimping zviteshi

Kushandisa siyana crimps zviteshi uye kwazara kuburikidza magetsi nehoro, haizoshandisi, chiedza Fixtures, uyewo kugadzwa switchboards. mano aya kubvumira yakarurama uye anokurumidza Connect mhangura rakasimba waya, nezano waya asi pasina pre-welds kana crimp chubhu muromo kupinda sikuruwa kiramba inouraya hazvibviri.

The zvazvisingarambiki zvakanakira ari sikuruwa zviteshi zvingasanganisira connectivity aruminiyamu wiring nendarira, uye hapana chikonzero unozotevera voga pakati vokukurukura.

Zvisinei, ichi mhando maererano hakusi pasina zvaunokanganisa. Iye unoda nguva nenguva Nokuraramisa randinogara mune Kumonyorora clamping zvinhu. Copper - zvikuru nyoro zvinhu, asingatani "leakage" kubvira pasi mutoro. Kana kunyange kuita kwokubatana achishandisa remvura-akatakura nokuramba wakaomerera panzira cleat zviteshi, nokuda imwe duku nzvimbo kuonana hukawanika pa mutoro uri nenharo uye kusunungura chitubu okunze, apo elasticity yavo zvinoderedza pamwe mukomboni yepamusoro.

Pike VS-nomoto

Kuti vave nechokwadi zvakanaka kuonana anowanzodanwa kushandiswa pokunamatidza kana nomoto kuti waya mhangura. Kuti akanakisisa nzira idzi? Zvechokwadi, nomoto. Chokwadi chokuti pokunamatidza - muitiro iri rakaoma chaizvo uye yakareba, kunyanya kana uchida kubatanidza nezano mhangura waya. Plus, ari commissural yeimwe pakupedzisira kuparadzwa nokuda pamberi wechitatu, zvikuru friable uye nyore fusible simbi - solder. Kuvapo yezwi mumweya Hudyu alloys siyana kunoita kuti chimiro rinoparadza nemakemikari nemamwe maitiro asina kunaka.

Kana nomoto rinoitwa mhangura waya, rokuti "kubatana" kazhinji haazombotaurwi nekuti monolithic remubatanidzwa inotengwa kubva kwakadaro zvesimbi. Sezvingatarisirwa, yeimwe izvi zvinosiyana chinyorwa yakaderera nemishonga, mauri kupisa haangambozvipembedzi kubudiswa.

pokunamatidza

Pakarepo zvinofanira kucherechedzwa kuti oparesheni iyi zvinoda mumwe mari zivo uye ruzivo. Ndezvokuti, asi unhu iri nani Achitsaudzira murombo pokunamatidza yeuka izvi.

Pokunamatidza mutoo chinotanga pre-pakurapa kumigumo waya kuputira uye oxides. Zvadaro vari vaikungurutsa, zvinenge zvakazara chaiwo fuma - pakuyerera hocus. Solder tambo mhangura asingagoni chete, asiwo aruminiyamu, chinhu chikuru - kusarudza zvakarurama nekubudisa uye solder. Kushandisa vachishingaira iine acid nekubudisa haina varumbidzwa, sezvazvakanyorwa kunodiwa kuramba tambo, zvakadai kuti mukomboni yakanyauka nokukurumidza.

Mumwe pokunamatidza anotora nguva refu, asi kana kuitwa nemazvo, akwirwe achava akavimbika uye yakasimba. Kamwe tambo dzaserera, zvinofanira nokungwarira insulated.

nomoto

Wekumusoro yepamusoro uye yakachengeteka kubatana anoumba munhu waya nomoto mhangura. The mumweya nokudyidzana waya hakurevi kusapfuudza mureza mwero kurwisa kwavo. Nzira iyi haatarisiri nguva yakawanda uye anoonekwa kuti zviri nyore kunzwisisa. In pamberi shoma ruzivo uye ruzivo nomoto pamusoro waya mhangura kumba doable.

Kana kuita nomoto basa ose nemitemo moto uye zvemagetsi kuchengeteka inofanira kuchengetwa zvachose. Kuti tidzivise hudiki uye kukuvara ziso vanofanira kushandisa unodzivirira midziyo nguva dzose - unodzivirira zvipfeko uye magiravhusi, nomoto Ngowani kana magogorosi.

Welding midziyo

Remubatanidzwa waya kubudikidza nomoto akaita apparatuses pakubhadhara siyana. Zviri chinonyanya zvakakunakira kushandisa inverter midziyo nokuda Welding waya mhangura, sezvo iri mhando mano muduku kukura uye uremu, mari simba zvinodyiwa uye zvakawanda Welding ano muzviruva vanoonekwa. zvakwakanakira ava kukwanisa kupa kuramba uchipfuta yemagetsi chinhu chakakombama.

Kana iwe zvakaronga chinokosha mari magetsi basa, kuunganidza chakanamwa nomoto muchina inverter zvachose zvakakodzera uye kwakarurama. Uyezve, midziyo iyi uchapisika nhema "uremu akafa" mune ramangwana.

Zvakakurukurwa nedanho nomoto waya kubva emhangura

Welding mhangura waya kunogona AC uye DC voltage dzimwe dziine 15-30 C. Zvakanaka kana mudziyo chinopa mukana kuchinja matsva.

Somuenzaniso, kuti weld miviri conductors ose 1,5 ba mhangura. neMM, zvakakwana 70 A. Nokuti nomoto pakati waya vatatu chete muchinjikwa chikamu Zvakakodzera kuwedzera kuitika 90 A. remubatanidzwa conductors matatu 2.5kb. mm zvinoda kubva 80 kusvika 100 A, mumwe nomoto waya yakafanana shanu - 120 A. Kana vakasarudzwa optimum nomoto razvino hakuitiki "akanamatira" pamusoro electrode uye chinhu chakakombama iri zvakakwana kugadzikana.
Nokuti nomoto pakati waya mhangura yaishandiswa kabhoni-mhangura "nepenzura" (electrodes). Kana kwete, zvinoita kushandisa kabhoni tsvimbo penzura mabhatiri.

nomoto miitiro

Kumuromo kwematanda wiring kureba 5-6 masendimita yakanga yakaidzwa ane insulating unhani uye vari kutangira yakakoswa kubva zvikamu kuputira, achikusiyirai 5-6 mm panopera imwe monyorora untwisted chimiro. Mazano aya anofanira kuparadzirwa, kuputirwa zvakafanana uye pedyo nomumwe. By Achitsaudzira waya matatu kana kupfuura, pakupera uchiri kuda kusiya mbiri chete vakasununguka muromo, uye vamwe akagura kutoda wokupedzisira ose pasi. Kana muchina haasi simba rakakwana, monyorora ichi kuchaita nyore kuumba uchanyangadika bead. Kana paine kuitika yakakwana muna nomoto midziyo inogona kuita nyore monyorora.

Uyezve nokuvhiringidza clamped Via clamping nomoto. Kana mudziyo uyu vasipo, unogona kushandisa pachena pingisi okuberekwa.

The akagadzirira remubatanidzwa yakanga welded kabhoni electrode. Panguva nomoto, waya emhangura vari vavhunduka akasiya untwisted miromo asati achiumba yakaumbwa bhora. Kuti vave nechokwadi yakavimbika zvemaziso uye magetsi kuonana waya, utsotso mapazi vanofanira kuva nechokwadi kuti kune stranding.

Duration nomoto haafaniri kupfuudza 2-3 masekonzi, zvimwe waya kuputira weld. Pashure kutonhora mukomboni yakakwana yakabereka voga kwayo kushandisa akawanda akaturikidzana kuti tepi kana chinokosha chivharo, PVC, kana nokupisa unyana Tubing.
