Chifukwa Kuwunika kwa Carbon Brush Kulephera kwa Dizilo Jenereta

Nthawi zambiri, ma seti ang'onoang'ono a jenereta a dizilo amagwiritsanso ntchito alternator yokhala ndi maburashi a kaboni.Alternator yokhala ndi maburashi a kaboni iyenera kusamalidwa ndikusinthidwa pafupipafupi.Today nkhaniyi makamaka za kusanthula mpweya burashi kulephera kwa jenereta ya dizilo .

Zomwe zimayambitsa kulephera kwa burashi ya kaboni:

Electromagnetic factor:

1. Pamene mphamvu yogwira ntchito kapena chisangalalo chamakono chisinthidwa, kutentha kwa carbon burashi kumasintha mwachiwonekere.Pamene exciter imasinthidwa, burashi ya kaboni imakhala yosalumikizana bwino ndi commutator, ndipo kukana kukhudzana ndi kwakukulu kwambiri;

2. Mkangano makulidwe a okusayidi filimu wa commutator kapena kuterera mphete kumayambitsa wosagwirizana kugawa mpweya burashi panopa;

3. Kapena kusintha kwadzidzidzi ndi kuyendayenda kwadzidzidzi kumayambitsa kugawa kwamagetsi pakati pa oyendetsa;

4. Kuchulukirachulukira kwa ma unit ndi kusalinganika;

5. Kusankhidwa kwa maburashi a kaboni sikumveka, ndipo matayala a maburashi a kaboni ndi osiyana;

6. Carbon brush quality mavuto, etc.

Zimango:

1. Pakati pa commutator siwolondola ndipo rotor ndi yosagwirizana;

2. Kugwedezeka kwakukulu kwa unit;

3. Kutsekereza pakati pa ma commutators kumatuluka kapena oyendetsa amatuluka;

4. Kukhudzana pamwamba pa carbon burashi si opukutidwa bwino, kapena pamwamba pa commutator ndi akhakula, chifukwa kukhudzana osauka;

5. Pamwamba pa commutator siukhondo;

6. Kusiyana kwa mpweya pansi pa mtengo uliwonse wosinthira ndi wosiyana;

7. Kuthamanga kwa kasupe pa burashi ya kaboni sikuli kofanana kapena kukula kwake sikuli koyenera;

8. Burashi ya kaboni ndi yotayirira kwambiri mu chotengera burashi ndikudumpha, kapena yothina kwambiri, ndipo burashi ya kaboni imamatira muchosungira.Kutenthako kudzachepetsedwa pamene kuthamanga kwa unit kumachepetsedwa kapena kugwedezeka kwabwino.

Zomwe zimapangidwira: pamene unit ikugwira ntchito mu gasi wowononga, kapena kusowa kwa okosijeni pamalo ogwiritsira ntchito unit, filimu yopangidwa mwachilengedwe yamkuwa ya oxide pamwamba pa commutator ikukhudzana ndi burashi ya carbon imawonongeka, ndipo kusintha kwa kukana kopanga mzere kulibenso.Panthawi yopangiranso filimu ya oxide pamalo olumikizana, spark ya commutator imakula.The commutator (kapena slip mphete) ndi dzimbiri ndi asidi mpweya kapena mafuta.Burashi ya kaboni ndi commutator ndizoipitsidwa.

Kusamalira burashi ya kaboni

A. Kuyang'anira ntchito. Limbikitsani kuyendera zida pafupipafupi komanso kosakhazikika.Nthawi zonse, ogwira ntchito ayenera kuyang'ana burashi ya jenereta kawiri pa tsiku (kamodzi m'mawa ndi kamodzi masana), ndi kuyeza kutentha kwa mphete yosonkhanitsa ndi burashi ya kaboni ndi thermometer ya infrared.Panthawi yochulukirachulukira m'chilimwe komanso mphamvu ikasinthasintha komanso mphamvu yamagetsi ikasinthasintha kwambiri, nthawi yoyezera kutentha imafupikitsidwa, ndipo burashi yatsopano ya kaboni yosinthidwayo iyenera kuyang'aniridwa kwambiri.Ogwiritsa ntchito nthawi zonse ayenera kuyeza kutentha kwa mphete yotolera ndi burashi ya kaboni ndi thermometer ya infrared.Lembani momwe zikuyendera pazida zoyendera.

B. Konzani ndikusintha. Yang'anani ndikuvomereza burashi ya carbon yomwe mwagula kumene.Yezerani kukana kwachilengedwe kwa burashi ya kaboni ndi kukana kwa kaboni burashi lead.Mtengo wotsutsa uyenera kutsatira wopanga ndi miyezo ya dziko.Kumvetsetsa bwino njira yosinthira maburashi a kaboni.Maburashi a kaboni omwe amagwiritsidwa ntchito pagawo lomwelo ayenera kukhala osasinthasintha komanso osasakanikirana.Musanayambe kusintha carbon burashi, mosamala pogaya mpweya burashi kuti pamwamba yake yosalala.Payenera kukhala kusiyana kwa 0.2 - 0.4mm mu chotengera burashi, ndipo burashi akhoza kusuntha mmwamba ndi pansi momasuka mu chotengera burashi.Mtunda pakati pa m'munsi m'mphepete mwa chofukizira burashi ndi malo ntchito commutator ndi 2-3mm.Ngati mtunda uli wochepa kwambiri, udzawombana ndi commutator pamwamba ndipo zimakhala zosavuta kuwonongeka.Ngati mtunda uli waukulu kwambiri, burashi yamagetsi ndiyosavuta kulumpha ndikutulutsa zonyezimira.Yesetsani kupangitsa kukhudzana kwa burashi ya kaboni kukhala wamkulu kuposa 80% ya gawo la kaboni burashi.Sinthani pafupipafupi, koma maburashi a carbon sayenera kusinthidwa nthawi zambiri.Chiwerengero cha maburashi a carbon omwe amasinthidwa nthawi imodzi sichidzapitirira 10% ya chiwerengero cha mitengo imodzi.Burashi ya kaboni yomwe pamwamba pake ndi 3mm kutsika kuposa pamwamba pa chotengera burashi iyenera kusinthidwa posachedwa.Nthawi iliyonse burashi ya kaboni ikasinthidwa, burashi ya kaboni yachitsanzo chomwecho iyenera kugwiritsidwa ntchito, koma samalani ndi kupulumutsa ndikugwiritsa ntchito mokwanira burashi ya kaboni.Burashi ya kaboni ikasinthidwa iyenera kuyeza ndi mita ya caliper ya DC, ndipo kuyesa kwa kutentha kudzachitika ndi thermometer ya infrared kuti maburashi a kaboni asatenthedwe chifukwa chakuchulukirachulukira.Pazovuta zodziwikiratu za zida monga kukwera ndi kutsika kwa ring ring kapena commutator commutator, mwayi wokonza mayunitsi udzagwiritsidwa ntchito kumanga ndi kutembenuza ndikupera.Limbikitsani kuwongolera ndi kuwongolera magwiridwe antchito kuti mupewe kutayikira kwamafuta a turbine pa mphete yotolera panthawi yogwira ntchito chifukwa cha kusamalidwa bwino kapena kusintha kosayenera kwa ntchito, ndikuwonjezera kukana kukhudzana pakati pa burashi ya kaboni ndi mphete yosonkhanitsa.Chogwiritsira ntchito burashi ndi chosungiramo burashi chidzasinthidwa mosamala panthawi yokonza zazikulu ndi zazing'ono za unit.Mukabwezeretsa ndikuyika chofukizira burashi, ngodya ndi mawonekedwe a geometric azikhala momwemo, ndipo kutsetsereka m'mphepete ndikutuluka m'mphepete mwa burashi ya kaboni kuyenera kufanana ndi commutator.

C. Kusamalira nthawi zonse. Tsukani pafupipafupi ndipo sungani malo osalala a burashi ya kaboni ndi mphete ya commutator kukhala yaukhondo.Pakakhala mphepo yamkuntho, iyenera kutsukidwa nthawi yake.Sinthani kuthamanga kwa masika pafupipafupi.Kuthamanga kwa carbon brush spring spring kumayenera kutsatira malamulo a wopanga jenereta kupanga mpweya burashi chimbalangondo yunifolomu kuthamanga.Pewani maburashi a kaboni pawokha kuti asatenthedwe kapena kuwotcha, ndi maburashi kuti asawotchedwe.Mavuto ntchito maburashi mpweya ayenera kuthetsedwa mu nthawi kupewa nkhanza mkombero ndi kuwononga ntchito yachibadwa wa unit.Maburashi a kaboni omwe amagwiritsidwa ntchito pagawo lomwelo ayenera kukhala osasinthasintha komanso osasakanikirana.Ogwira ntchito yosamalira ayenera kusamala kwambiri poyang'anira ndi kukonza.Kuluka tsitsi kumayikidwa mu chipewa ndipo ma cuffs amangidwe kuti zovala ndi zopukuta zisamangidwe ndi makina.Pamene mukugwira ntchito, imani pazitsulo zotetezera ndipo musagwirizane ndi mizati iwiri kapena mtengo umodzi ndi gawo lokhazikika panthawi imodzi, komanso anthu awiri sagwira ntchito nthawi imodzi.Katswiriyu ayenera kukhala wodziwa kusintha ndi kuyeretsa mphete yamoto.
