5. Tshawb xyuas seb cov twj tso kua dej submersible puas ua tiav thiab teeb tsa kom raug raws li daim duab sib dhos hauv phau ntawv tshem tawm cov ntxaij lim dej thiab tig lub coupling kom pom tias nws tig tau yooj yim.
6. Unscrew cov dej ntsia hlau thiab sau cov kab noj hniav nrog cov dej huv, tsis muaj corrosive (ceeb toom. Nco ntsoov sau nws), tom qab ntawd ceev cov dej screws. Tom qab 12 teev ntawm kev txhaj tshuaj dej, qhov rwb thaiv tsev ntawm lub cev muaj zog yuav tsum tsis txhob tsawg dua 150M Q thaum ntsuas nrog 500V co lub rooj.
7. Cable sib koom tes, txiav tawm lub tes tsho roj hmab 120mm los ntawm ib kawg ntawm cov khoom siv tawm thiab cov khoom sib txuam nrog ib tus neeg siv hluav taws xob riam, stagger qhov ntev ntawm peb cov xov hlau nyob hauv ib kauj ruam, tev tawm 20mm tooj liab tub ntxhais, txhuam cov oxide. txheej nyob rau sab nraud ntawm cov hlau tooj liab nrog ib rab riam los yog cov ntaub xuab zeb, thiab ntxig rau ob txoj hlua txuas rau hauv palir. burrs ntawm qhov chaw. Tom qab ntawd, rau peb lub pob qij txha, siv polyvester rwb thaiv tsev daim kab xev los qhwv lawv nyob rau hauv ib tug semi stacked yam rau peb lavers. Qhwv ob qhov kawg ntawm txheej txheej nruj nreem nrog nyion xov, thiab tom qab ntawd siv cov txheej txheem semi stacked los qhwv daim kab xev rau peb txheej. qhwv lub outellaer nrog high-pressure rwb thaiv tsev daim kab xev rau peb txheej. Thaum kawg, quav peb txoj hlua ua ke thiab rov qhwv lawv rau tsib txheej nrog daim kab xev siab. Txhua txheej yuav tsum tau nruj nreem khi, thiab cov interlayer pob qij txha yuav tsum nruj thiab fimm kom tsis txhob muaj dej los ntawm kev nkag mus thiab ua puas lub rwb thaiv tsev, Tom qab qhwv, tsau nyob rau hauv dej ntawm chav tsev kub ntawm 20 'c rau 12 teev, thiab ntsuas lub rwb thaiv tsev tiv thaiv nrog ib tug co lub rooj. , uas yuav tsum tsis pub tsawg tshaj 100M Ω

Daim duab txuas cable thaiv txheej txheem yog raws li hauv qab no:

8. Siv multimeter los xyuas seb cov xov hlau peb-theem puas txuas thiab seb qhov DC tsis kam yog kwv yees li qhov sib npaug.
9. Xyuas seb puas muaj peev xwm ntawm lub Circuit Court thiab transformer yog overloaded, thiab ces txuas lub overload tiv thaiv hloov los yog pib cov khoom. Saib Table 2 rau cov qauv tshwj xeeb, thiab tom qab ntawd hliv ib lub thoob dej rau hauv lub twj tso kua mis los ntawm lub qhov dej twj tso kua mis kom lubricate cov roj hmab bearings hauv lub twj tso kua mis, thiab tom qab ntawd muab lub twj tso kua mis submersible fais fab tso ncaj thiab khov kho.Start (tsis pub ntau tshaj ib ob) thiab xyuas seb qhov kev taw qhia lub kauj tsheb puas zoo ib yam nrog lub kauj tsheb. Yog tias tsis yog, sib pauv ob qhov txuas ntawm peb-theem cable.Tom qab ntawd nruab lub lim thiab npaj mus rau hauv qhov dej. Yog tias siv rau lub sijhawm tshwj xeeb (xws li kwj dej, kwj dej, dej ntws, pas dej, pas dej, thiab lwm yam), lub twj tso kua mis hluav taws xob yuav tsum muaj kev ntseeg siab.
