(5) Lub rotor ncej ntawm lub convex phaj synchronous lub cev muaj zog yuav tsum tau disassembled thiab sib sau ua ke symmetrically, thiab yuav tsum tau them nyiaj mloog mus tswj qhov sib npaug ntawm lub rotor.
(6) Cov ntsiab lus hauv qab no yuav tsum tau them sai sai rau hauv cov txheej txheem ntawm lub cev muaj zog nqa, dismantling core rub, thiab qhov chaw cia:
a. Tiv thaiv kev puas tsuaj rau lub cable kawg.
b Ua kom rov pib dua lub cim tseem ceeb xws li xov lub taub hau, lub hau kawg, txhuam hniav, thiab lwm yam, thiab muab cov khoom me me rau hauv cov hnab yas tshwj xeeb.
c Ua ntej rub tawm lossis txhim kho lub rotor, tiv thaiv cov ntawv xov xwm, lub nplhaib sau, commutator thiab winding xaus kom tsis txhob muaj kev cuam tshuam ntawm cov hlua hlau steel. Tom qab rub tawm lub rotor, xyuas cov winding, hlau core, qhov sib txuas, qhov kawg khi, thiab lwm yam rau cov pob hauv lub sijhawm, thiab kho cov khoom tawg hauv lub sijhawm.
d. Qhov chaw uas cov hlua khi hlua khi rau lub rotor yuav tsum tau muab cov ntaub qhwv ntoo.
(7) Nws yog txwv tsis pub tuav lub winding nrog cov khoom hlau. Siv ntoo, xyoob los yog insulating fiberboard los ntxuav lub winding av.
(8) Thaum yaug lub cev muaj zog nrog chav dej thiab dej, qhov dej ntws tawm yuav tsum tswj tau ntawm o. 1 rau o. 15MPa ntau yam.
(9) Thaum siv cov cua compressed los tshuab cov plua plav, ua tib zoo saib xyuas cov huab cua, thiab tsis muaj dej tuaj yeem raug cua tshuab mus rau qhov cua.
(10) Thaum tswj qhov yuam kev hauv zos lossis hloov winding, yuav tsum tau them nyiaj rau kev tiv thaiv lwm yam windings. Thaum embedding soft windings, tsis txhob ua puas lub rwb thaiv tsev ntawm cov xov hlau thiab cov rwb thaiv tsev ntawm cov qhov.
(11) Thaum siv cov cuab yeej tshem tawm cov kabmob, ua tib zoo tiv thaiv lub thimble qhov ntawm lub ncej.
(12) Lub tshuab ci yuav tsum muaj ib tus neeg tshwj xeeb ntawm lub luag haujlwm, qhia qhov ntsuas kub ntawm qhov ci, thiab ua cov ntaub ntawv ci.
(13) Qhib nplaim taws yuav tsum tsis txhob tiv tauj cov volatiles ntawm insulating xim los yog cov ntaub ntawv insulating.
(14) Yuav tsum tsis pub tsawg tshaj li ob tus neeg thaum lub sij hawm ntsuas high-voltage ntawm lub cev muaj zog. Lub chaw kuaj mob yuav tsum tau muaj kev tiv thaiv, thiab yuav tsum tau dai daim ntawv ceeb toom, thiab ib tus neeg tshwj xeeb yuav tsum raug xa mus saib xyuas. (15) Tom qab ntsuas qhov ntsuas hluav taws xob lossis qhov ntsuas hluav taws xob siab, lub tshuab hluav taws xob yuav tsum tau tawm mus rau hauv av ob peb zaug.
(16) Ua ntej kaw lub stator, xyuas cov khoom tsis nco qab hauv cov pa tawm, cov pa cua thiab lwm cov kab noj hniav.
3). Kev ceev faj rau kev nyab xeeb hauv kev ua haujlwm
(1) Ua ntej qhov kev xeem thauj khoom, nws yog ib qho tsim nyog los ntsuas qhov kev sib hloov ntawm lub cev muaj zog ib leeg los xyuas seb nws puas ua tau raws li qhov xav tau ntawm cov txheej txheem.
(2) Thaum lub sijhawm ua haujlwm, ib zaug pom qhov txawv txav xws li suab nrov txawv txav, tsis hnov tsw, pa taws thiab hluav taws, kev vibration hnyav, kub dhau, dhau-tam sim no, thiab lwm yam tau pom, lub tsheb yuav tsum nres tam sim ntawd.
(3) Nyob rau hauv lub xeev txias, nws raug tso cai pib mus txog 3 zaug tsis tu ncua, nrog rau ncua sij hawm li 5 feeb txhua zaus. Tsuas yog ib qho pib raug tso cai hauv lub xeev kub. Thaum cuam tshuam nrog kev sib tsoo, ntau qhov pib raug tso cai.
