Uhlalutyo lwembangela yeCarbon Brush Failure ye-Diesel Generator

Ngokubanzi, ezinye iiseti ezincinci zejenereyitha yedizili nazo zisebenzisa ialternator enebrashi zekhabhoni.I-alternator ene-carbon brushes kufuneka igcinwe kwaye itshintshwe rhoqo.Namhlanje eli nqaku ikakhulu malunga uhlalutyo carbon brush ukusilela ijenereyitha yedizili .

Izinto ezikhokelela kukusilela kwebrashi yekhabhoni:

Izinto zombane:

1. Xa amandla asebenzayo okanye i-excitation current ilungiswa, i-spark ye-carbon brush iyatshintsha ngokucacileyo.Xa i-exciter iguqulwa, ibrashi yekhabhoni inxibelelana kakubi kunye ne-commutator, kwaye ukuchasana koqhagamshelwano kukhulu kakhulu;

2. Ubunzima obungalinganiyo befilimu ye-oxide ye-commutator okanye i-slip ring ibangela ukusabalalisa okungalinganiyo kwe-carbon brush yangoku;

3. Okanye ukutshintshwa komthwalo ngesiquphe kunye nesekethe emfutshane ngesiquphe kukhokelela ekusasazweni kombane ongaqhelekanga phakathi kwabahambisi;

4. Ukugcwala kweyunithi kunye nokungalingani;

5. Ukukhethwa kweebrashi zekhabhoni akunangqiqo, kwaye izithuba zeebrashi zekhabhoni zihlukile;

6. Iingxaki zekhwalithi ye-Carbon brush, njl.

Imiba yoomatshini:

1. Iziko le-commutator alichanekanga kwaye i-rotor ayilingani;

2. Ukungcangcazela okukhulu kweyunithi;

3. Ukufakwa kwe-insulation phakathi kwabahambisi baphumela ngaphandle okanye i-commutator iphuma;

4. Indawo yokudibanisa ibrashi yekhabhoni ayicolwanga kakuhle, okanye umphezulu we-commutator urhabaxa, okukhokelela ekudibaneni kakubi;

5. Umphezulu we-commutator awucocekanga;

6. Isikhewu somoya phantsi kwepali nganye yokutshintsha yahlukile;

7. Uxinzelelo lwentwasahlobo kwibrashi yekhabhoni ayilingani okanye ubungakanani abufanelekanga;

8. Ibrashi yekhabhoni ikhululekile kakhulu kwisibambi sebrashi kwaye iyatsiba, okanye iqine kakhulu, kwaye ibrashi yekhabhoni ibambeke kwisibambi sebrashi.I-spark iya kuncitshiswa xa isantya sokuhamba seyunithi sincitshisiwe okanye i-vibration iphuculwe.

Imichiza yeMichiza: xa iyunithi isebenza kwigesi eyingozi, okanye kukho ukungabikho kweoksijini kwindawo yokusebenza yeyunithi, ifilimu ye-copper oxide eyenziwe ngokwemvelo kumphezulu we-commutator edibana ne-carbon brush yonakalisiwe, kwaye uguqulo lwendlela yokuchasa eyenziweyo ayisekho.Ngexesha lenkqubo yokwenza kwakhona ifilimu ye-oxide kwindawo yokudibanisa, i-spark ye-commutator iqinisa.I-commutator (okanye i-slip ring) idliwe yigesi ye-asidi okanye igrisi.Ibrashi yekhabhoni kunye ne-commutator zingcolile.

Ukugcinwa kwebrashi yekhabhoni

A. Ukuhlolwa komsebenzi. Ukuqinisa uhlolo lwezixhobo zokujikeleza rhoqo kunye nezingekho mgaqweni.Kwiimeko eziqhelekileyo, abasebenzi kufuneka bahlolisise i-carbon brush yejenereyitha kabini ngosuku (kanye ekuseni nakanye emva kwemini), kwaye balinganise ubushushu bendandatho yomqokeleli kunye ne-carbon brush nge-thermometer ye-infrared.Ngexesha lomthwalo ophakamileyo ehlotyeni naxa amandla asebenzayo kunye namandla ombane eguquguquka kakhulu, isithuba somlinganiselo wobushushu siya kucuthwa, kwaye ibrashi yekhabhoni efakwe endaweni yayo iya kuxhomekeka kuhlolo olungundoqo.Abasebenzisi beemeko kufuneka balinganise rhoqo ubushushu beringi yomqokeleli kunye nebrashi yekhabhoni ngethemometha ye-infrared.Rekhoda iimeko zokusebenza zezixhobo zokuhlola iipatroli.

B. Lungisa kwaye ubuyisele. Jonga kwaye wamkele ibrashi yekhabhoni esanda kuthengwa.Ukulinganisa ixabiso lendalo loxhathiso lwebrashi yekhabhoni kunye nokuxhathisa koqhagamshelwano lwelothe yebrashi yekhabhoni.Ixabiso lokuchasana liya kuthobela umenzi kunye nemigangatho yelizwe.Bamba ngokungqongqo inkqubo yokutshintsha iibrashi zekhabhoni.Iibrashi zekhabhoni ezisetyenziswe kwiyunithi efanayo kufuneka zihambelane kwaye azikwazi ukuxutywa.Ngaphambi kokuba utshintshe ibrashi yekhabhoni, gaya ngononophelo ibrashi yekhabhoni ukwenza umphezulu wayo ube mpuluswa.Kufuneka kubekho isithuba se-0.2 - 0.4mm kwisibambi sebrashi, kwaye ibrashi inokunyuka ihle ngokukhululekileyo kwisibambi sebrashi.Umgama phakathi komda ophantsi womphathi webrashi kunye nomgangatho osebenzayo we-commutator ngu-2-3mm.Ukuba umgama uncinci kakhulu, uya kungqubana nomphezulu we-commutator kwaye kube lula ukonakala.Ukuba umgama mkhulu kakhulu, ibrashi yombane kulula ukutsiba kwaye ivelise iintlantsi.Zama ukwenza umphezulu woqhagamshelwano webrashi yekhabhoni ube mkhulu kune 80% yecandelo lomnqamlezo webrashi yekhabhoni.Faka endaweni yakho rhoqo, kodwa iibhrashi zekhabhoni akufuneki zitshintshwe amaxesha amaninzi.Inani leebhrashi zekhabhoni ezitshintshwe ngexesha elinye aliyi kudlula i-10% yenani elipheleleyo lepali enye.Ibrashi yekhabhoni umphezulu wayo uyi-3mm ngaphantsi kunomphezulu wesibambi sebrashi iya kutshintshwa ngokukhawuleza.Ngalo lonke ixesha ibrashi yekhabhoni itshintshwa, ibrashi yekhabhoni yomfuziselo ofanayo kufuneka isetyenziswe, kodwa nikela ingqalelo ekugcinweni nasekusebenziseni ngokupheleleyo ibrashi yekhabhoni.Ibrashi yekhabhoni emva kokutshintshwa kufuneka ilinganiswe ngemitha yecaliper yeDC, kwaye uvavanyo lobushushu luya kwenziwa ngethemometha ye-infrared ukuthintela iibhrashi zekhabhoni nganye ekutshiseni ngokugqithisileyo ngenxa yokudlula.Kwiingxaki ezicacileyo zezixhobo ezinje ngeprotrusion kunye nokudakumba kweringi yokutyibilika okanye isihambisi sokuhambisa i-commutator, ithuba lokugcinwa kweyunithi liya kusetyenziselwa ukuqinisa kunye nokujika kunye nokusila.Ukuqinisa umgangatho wokugcinwa kunye nokulawula ukusebenza ukuze ugweme ukuvuza kweoli ye-turbine kwindandatho yomqokeleli ngexesha lokusebenza kweyunithi ngenxa yomgangatho ophantsi wokugcinwa okanye ukulungiswa kokusebenza okungafanelekanga, kunye nokwandisa ukuchasana koqhagamshelwano phakathi kwe-carbon brush kunye nesese somqokeleli.Isibambi sebrashi kunye nesibambi sebrashi siya kulungelelaniswa ngononophelo ngexesha lolondolozo olukhulu kunye oluncinci lweyunithi.Xa ubeka umva kwaye ufaka isibambi sebrashi, i-engile kunye ne-geometric position iya kuba kwindawo yokuqala, kwaye ukutyibilika emphethweni kunye nokuslayida ngaphandle kwe-carbon brush kufuneka ihambelane ne-commutator.

C. Ukugcinwa rhoqo. Coca rhoqo kwaye ugcine umphezulu ogudileyo webrashi yekhabhoni kunye neringi yesiliphu yesihambi icocekile.Kwimeko yemozulu enomoya, kufuneka icocwe kwangethuba.Lungisa uxinzelelo lwentwasahlobo rhoqo.Uxinzelelo lwe-carbon brush spring luya kuhambelana nemimiselo ye umenzi wejenereyitha ukwenza ibrashi yekhabhoni ibhere uxinzelelo olufanayo.Thintela iibhrashi zekhabhoni zomnye umntu ekutshiseni ngokugqithisileyo okanye iintlantsi, kunye neebrashi zokubrasha ukuba zingatshi.Iingxaki ekusebenzeni kweebrashi zekhabhoni kufuneka zipheliswe kwangethuba ukuphepha umjikelezo onoburhalarhume kunye nomngcipheko wokusebenza okuqhelekileyo kweyunithi.Iibrashi zekhabhoni ezisetyenziswe kwiyunithi efanayo kufuneka zihambelane kwaye azikwazi ukuxutywa.Abasebenzi bolondolozo baya kuqaphela ngakumbi ngexesha lokuhlolwa nokugcinwa kwalo.I-hair braid iya kufakwa kumnqwazi kwaye ii-cuffs ziya kufakwa ukuze zithintele iimpahla kunye nezinto zokucima ukuba zixhonywe ngumatshini.Xa usebenza, yima kwi-insulating pad kwaye ungaqhagamshelani nezibonda ezimbini okanye i-pole enye kunye nenxalenye yokumisa ngexesha elifanayo, kwaye abantu ababini bangasebenzi ngexesha elinye.Igcisa kufuneka libe namava ekulungiseni nasekucoceni iringi yokutyibilika yemoto.
