Cov teeb meem rau txhuam iav

Yam khoom

Teeb meem

Yog vim li cas

Kho tshuaj

1

Txhuam yog fragmented.

Lub txim hluav taws xob loj dua.

Kev khiav hauj lwm nto txuas ntawm txhuam lub thawv thiab nws cov commutator tsis ntsug.

Qhov kev ncua deb ntawm txhuam lub thawv rau nws qhov chaw ua haujlwm ntawm lub commutator yog siab dhau.

Txhuam qhov loj dua los yog xoob dhau.

Loosing fastening bolt thiab re-kho;

Kho rau 2-4mm;

Hloov lub thawv txhuam tshiab.

2

Tom qab txhuam yog tig mus rau pem hauv ntej thiab thim rov qab, ob qhov hnav nto tau tshwm sim.

Vim yog txhuam qhov deformation thiab tsis yog - tsim nyog squae qhov txheej txheem, flared kawg yog generated los yog xoob square qhov.

Hloov lub thawv txhuam tshiab los yog nruab ib sab saum toj - txhuam txhuam

3

Vim lub txhuam bounced, nws cov hluav taws xob spark yog generated.

Commutator lug deformation;

Interlayer mica yog projecting;

Copper pos thiab cuspidal ntug yog generated;

Tsis tshua muaj siab ntawm txhuam.

Loosen fastening bolt thiab rov- kho;

Hloov undercut mica;

Re-chamfering;

Kho lub siab los yog hloov lub caij nplooj ntoos hlav;

4

Cov txhuam hniav dhau -rhuab.

Siab loj heev ntawm txhuam;

Vim lub siab tsis sib npaug ntawm cov txhuam hniav, nws cov load tsis sib npaug.

Kho lub siab los yog hloov lub caij nplooj ntoos hlav;

Hloov tsis sib npaug - qhov siab txhuam thiab kho qhov siab ntawm tus txhuam hniav

5

Cov txhuam hniav yog hnav sai heev.

Qib huv dhau rau lub commutator thiab lub kaum ntse ntse ntawm lub burr yog qhov loj dua.

Vim lub load qis dhau lawm, cov yeeb yaj kiab tsis tuaj yeem tsim tawm.

qhuav dhau los yog noo noo dhau ntawm nws qhov kev ua haujlwm

Re-lathing thiab chamfering;

Nce load los yog txo kom muaj nuj nqis ntawm txhuam;

Txhim kho qhov xwm txheej ua haujlwm lossis hloov qib txhuam

6

Cov txhuam hniav yog jammed hauv nws lub thawv txhuam.

Txhuam qhov deformation;

Loj dhau ntawm qhov txhuam;

Vim qhov txhuam mos dhau lawm, nws cov plua plav carbon yog jammed hauv nws lub qhov square.

Kab luv luv ntawm braid txhuam;

Nias ntiv tes yog jammed thiab nias rau ntawm txhuam.

Hloov lub thawv txhuam los yog rov- txheej txheem square qhov;

Sib tsoo txhuam kom tsim nyog;

Tshuab me ntsis los yog hloov txhuam qib;

Hloov txhuam tshiab los yog daws qhov teeb meem;

7

Lub siab ntawm txhuam yog loj dua.

Vim tsis muaj kev kho cua sov rau lub caij nplooj ntoos hlav, nws qhov hardness tsis txaus.

Vim lub nplhaib hluav taws kub ntawm lub cev muaj zog, lub caij nplooj ntoos hlav yog annealed tom qab tshaj -rhuab.

Hloov lub caij nplooj ntoos hlav tshiab lossis rov- kho cua sov

8

Txhuam -ring breakage

Ntau dhau hardness;

Vim yog xoob braid txhuam, lub caij nplooj ntoos hlav zoo li conductive.

Inefficient rivet sib koom ntawm tas li lub caij nplooj ntoos hlav, nws breakage yog generated.

Hloov cov hardness tsim nyog rau lub caij nplooj ntoos hlav thiab xaiv RO nrog 40-45;

Hloov cov txhuam hniav tshiab nrog insulating thaub qab;

Hloov lub caij nplooj ntoos hlav tshiab thiab txhim kho cov txheej txheem rivet;

9

Txhuam-box vibration

Loose fastening Cheebtsam

Re-kaw

10

Txhuam-box sparkwear

Lub txim loj dhau los yog lub nplhaib hluav taws kub;

Vim yog kev khiav haujlwm tsis zoo- nyob nruab nrab ntawm tus txhuam hniav thiab cov commutator, arc tsim tawm.

Txhuam lub thawv poob lawm.

Tshem tawm lub nplhaib hluav taws kom txo tau hluav taws xob;

Cov txheej txheem tsim nyog khiav -in;

Re-welding lossis fastening

11

Txhuam- pas nrig hauv av tawg

Vim cov plua plav nkig tawg los ntawm cov yas los yog epoxy txhuam pas, creepage thiab tawg.

Flask yog tawg.

Vim muaj plua plav tsub zuj zuj ntawm cov yas txhuam pas rau nws sab nraud Polytetrafluoroethylene raj, nws tawg yog generated.

Hloov tus pas txhuam hniav tshiab lossis txhim kho cov txheej txheem;

Hloov lub raj mis Tuam Tshoj tshiab;

Txais ib qho - txhaj tshuaj - nrog - ob - ntu pwm kom tshem tawm qhov khoob.

12

Loose Brush holder nplhaib

Loose fastening thiab xoob qhov chaw tus pin

Txais kev tso npe cim kom zoo dua rov qab thiab nrawm dua;

Hloov tus pin qhov chaw;
