(1) luv Circuit Court ntawm commutator ntu
Lub thiaj li hu ua luv luv Circuit Court nruab nrab ntawm cov commutator ntu txhais tau hais tias muaj kev sib txuas luv luv ntawm ob ntu uas nyob ib sab ntawm lub commutator. Short circuit ntawm commutator ntu. Cov sparks loj yuav tshwm rau saum npoo ntawm lub commutator; Thaum qhov luv luv Circuit Court yog qhov hnyav, lub nplhaib hluav taws yuav tshwm sim ntawm qhov chaw ntawm lub commutator.

Kev kho ntawm luv luv Circuit Court ntawm cov commutator ntu yog raws li nram no:
① Kev ntxuav nrog daim ntawv ntxuav thaum lub armature winding yog burnt vim luv luv Circuit Court txhaum, qhov txhaum point yuav nrhiav tau los ntawm txoj kev soj ntsuam. Txhawm rau txiav txim siab seb qhov kev ua txhaum luv luv tshwm sim hauv lub voj voog lossis nruab nrab ntawm cov ntu commutator, lub winding hlau taub hau txuas nrog ntu commutator yuav tsum raug txiav, thiab tom qab ntawd siv lub teeb txheeb xyuas seb puas muaj luv luv ntawm lub commutator. segments, xws li nyob rau saum npoo ntawm commutator ntu. Yog tias pom muaj hluav taws xob luv luv, lossis lub txim taws hlawv qhov caws pliav, feem ntau yog siv daim ntawv ntxuav hauv daim duab 227 txhawm rau txhawm rau tshem tawm cov hlau luv luv, txhuam hmoov, tshuaj corrosive, thiab lwm yam., kom txog rau thaum lub teeb pom kev zoo siv los ntawm cov khoom siv hluav taws xob. xyuas tias tsis muaj luv luv. Thiab siv mica hmoov thiab shellac los yog mica hmoov, epoxy resin thiab polyamide resin (650) los sib tov rau hauv ib qho muab tshuaj txhuam, tom qab ntawd sau cov grooves thiab cia nws tawv thiab qhuav.
②Clean the V-groove and V-ring of the commutator block If the short circuit between the chips cannot be eliminated after carefully removing the external debris between the chips. At this time, the commutator must be disassembled, and the V-groove and V-ring of the commutator group must be carefully cleaned. Before disassembling the commutator, wrap a layer of elastic paper with a thickness of 0.5 to 1 mm on the outer circumference of the commutator for insulation, and mark the fault location, and then cover the stacking die, and then Take the commutator apart. Further check the faults between the commutator segments, the surface of the V-groove and the V-ring, and deal with them according to different faults.
③ Hloov cov nplooj ntawv mica ntawm cov nplooj ntawv Yog tias qhov luv luv ntawm cov nplooj ntawv tsis tuaj yeem tshem tawm los ntawm txoj kev saum toj no, tsuas yog cov nplooj ntawv mica tuaj yeem hloov tau. Txoj kev hloov cov inter-chip mica flakes yog raws li nram no.
Muab cov commutator disassembled saum toj no rau ntawm lub phaj tiaj tus, khij lub faulty commutator segments, thiab ces fasten nws nrog ib tug roj hmab nplhaib, ces tshem tawm cov hlau hoop los yog weft-dawb iav hlau, thiab siv ib tug sharpened ib feem ntawm lub dav saw hniav. yog muab tso rau ntawm lub faulty pieces, tom qab loosening, lub faulty commutator piece yog rub tawm, thiab ib tug tshiab commutator piece ntawm tib specification raws li lub faulty commutator piece yog tso.
Tom qab hloov lub commutator phaj, siv hlau hoops (nrog tuab cardboard sab hauv) kom ceev cov commutator phaj pawg. Thaum tshav kub kub lub commutator block rau 165 ℃ ± 5 ℃, zawm cov ntsia hlau thawj zaug, thiab siv lub teeb calibration los xyuas seb qhov luv luv ntawm cov blocks tau raug tshem tawm tom qab txias. Yog tias nws tsis raug tshem tawm, koj yuav tsum ua tib zoo nrhiav qhov ua rau tsis ua haujlwm lossis rov ua haujlwm saum toj no; Yog tias qhov luv luv ntawm cov chips tau raug tshem tawm, ua kev sib dhos.
