Izici ezisebenzayo zamabhulashi ekhabhoni

Functional characteristics of amabhulashi e-carbon

Umsebenzi we-carbon brush ikakhulukazi ukuqhuba ugesi ngenkathi uhlikihla ensimbi. Akufani nalapho insimbi ihlikihla futhi ihambisa ugesi ensimbi; Amabhulashi ekhabhoni awakwenzi ngoba ikhabhoni nensimbi yizici ezimbili ezihlukene. Iningi lokusetshenziswa kwalo lisetshenziswa kumamotho, futhi ubujamo buhlukahlukene, isikwele nesiyingi, njalonjalo.

Amabhulashi ekhabhonizilungele zonke izinhlobo zezinjini, amajeneretha, kanye nemishini ye-ekseli. Inokusebenza okuhle kokuhlehla nempilo ende yesevisi. Ibhulashi lekhabhoni lisetshenziswa ku-commutator noma indandatho eshelelayo yenjini. Njengomzimba othintana naye oslayidayo oholayo futhi ongenisa okwamanje, unokusebenza kahle kukagesi, ukuqhutshwa kwe-thermal kanye nokusebenza kokugcoba, futhi unamandla athile omshini kanye nomzwelo wezinhlansi zokushintsha. Cishe zonke izinjini zisebenzisa amabhulashi ekhabhoni, ayingxenye ebalulekile yenjini. Isetshenziswa kakhulu kumajeneretha ahlukahlukene e-AC kanye ne-DC, ama-motor synchronous, amabhethri e-DC motors, izindandatho zokuqoqa izimoto ze-crane, izinhlobo ezahlukene zemishini yokushisela nokunye. Ngokuthuthuka kwesayensi nobuchwepheshe, izinhlobo zezinjini kanye nezimo zokusebenza zokusetshenziswa ziya ngokuya zihlukahluka

Indima ethize yeamabhulashi e-carbon

1. Engeza i-current yangaphandle (i-excitation current) ku-rotor ejikelezayo (i-input current) nge-carbon brush;

2. Yethula ukushaja okumile ku-shaft enkulu phansi (ibhulashi lekhabhoni eligxiliwe) ngebhulashi lekhabhoni (okukhiphayo kwamanje);

3. Hola i-shaft enkulu (umhlabathi) kudivayisi yokuvikela ukuze uvikeleke umhlabathi we-rotor futhi ulinganise i-voltage yomhlabathi eqondile nengalungile ye-rotor;

4. Shintsha isiqondiso se-current (emotweni ye-commutator, ibhulashi lidlala indima yokushintsha)

Ngaphandle kwe-induction AC motors asynchronous. Kukhona amanye ama-motor, inqobo nje uma i-rotor inendandatho yokushintsha.

Umgomo wokukhiqiza amandla ukuthi ngemva kokuba insimu kazibuthe isike intambo, kukhiqizwa umsinga ocingweni. Ijeneretha isika intambo ngokuzungezisa inkambu kazibuthe. Insimu yamagnetic ejikelezayo yi-rotor, futhi izintambo ezisikiwe ziyi-stator.
