kev tiv thaiv ntawmcov twj submersible
1. Hluav taws xob saum toj no
(1) Nco ntsoov xyuas qhov kev khiav hauj lwm voltage thiab ncaj qha tam sim no ntawm lub twj tso kua mis submersible. Peb-theem hluav taws xob ntsuas los ntawm lub ntsuas dej siab yuav tsum yog qhov sib xws, thiab ntawm 340 ~ 420V, peb theem ncaj qha tam sim no ntsuas los ntawm lub ntsuas hluav taws xob tam sim no yuav tsum yog qhov sib xws, thiab nws yuav tsum yog 0.5 ~ 1 npaug ntawm qhov ncaj qha tam sim no.
(2) Tsis tu ncua xyuas cov thermal rwb thaiv tsev ntawm lub twj tso kua mis submersible rau hauv av. Tom qab qhov txawv txav mus rau 4 ~ 6h txuas ntxiv, nres thiab ntsuas qhov kev tiv thaiv hluav taws xob ntawm lub cev muaj zog winding rau hauv av nrog megohmmeter, uas yuav tsum yog> 0.5MΩ. Rau cov twj submersible uas tau tso tseg rau lub sijhawm luv luv, kev tshuaj xyuas yuav tsum tau ua ua ntej siv.
(3) Ua ntej pib lub tshuab, xyuas qhov rhiab heev ntawm cov thermal repeater thiab seb qhov kev ua haujlwm ntawm lwm yam kev tiv thaiv kev teeb tsa puas txawv txav.
(4) Xyuas seb lub cable puas puas los yog tsis. Hais txog cov roj-immersed submersible electric twj tso kua mis, them sai sai rau qhov kev puas tsuaj ntawm cov roj to ntawm hluav taws xob twj tso kua mis ntawm insulating roj hmab ntawm lub cable.
2. mechanically
(1) Ib txwm tshuaj xyuas cov neeg kho tshuab foob ntawm lub twj tso kua mis submersible. Qhib cov roj qhov ntsia hlau thiab tso cov roj ntau ntau. Yog tias cov roj muaj cov dej noo, nws tau qhia tias qhov sib tsoo sab sauv (lossis qhov sib tsoo hauv qab) yog kaw nrog dej seepage. Lub thawv sealing yuav tsum tau hloov thiab cov roj khov tshiab yuav tsum tau muab tshem tawm. Yog tias cov roj qhov tsis muaj roj los yog cov roj tsis zoo, nws yuav tsum tau ntim cov roj (No. 5 lossis No. 10 mechanical oil, sewing oil or transformer oil) los yog hloov cov roj tshiab.
(2) For the new or replaced submersible pump, the water sealing plug should be turned off after 50 hours of use, and the amount of oil (water) leaked should be checked. If it is less than 5ml, the seal is abnormal. If it can be used continuously, if it is more than 5ml, the oil (Water) After draining, tighten the sealing plug, and make a second inspection after 50 hours of continuous use. If it is still >5m1, nws qhia tias muaj teeb meem nrog kev sib khi. Rau lub twj tso kua mis submersible siv, cov dej xau yuav tsum tau kuaj ib hlis ib zaug, thiab nws yuav tsum tsawg dua 25ml, thiab nws tuaj yeem siv tsis tu ncua tom qab ziab.
(3) Tshawb xyuas lub xeev kev co ntawm lub twj tso kua mis lub cev muaj zog. Lub synchronous ceev yog n0=3000r/min, 1500r/min, 1000r/min, 750r/min, thiab Cov nqi vibration yog sib npaug rau δ Tsawg dua lossis sib npaug ntawm 0.06mm, 0.1mm, 0.13mm, 0.16mm.
(4) Tsis tu ncua saib xyuas cov kabmob ntawm lub twj tso kua mis submersible. Xyuas seb cov kabmob puas muaj roj tsawg, seb lub nplhaib sab hauv lossis lub nplhaib sab nraud puas tau khiav, thiab seb cov kabmob puas yuav tsum tau hloov (rau cov kabmob ntawm lub twj tso kua mis dej, nws yog qhov zoo tshaj los hloov nws txhua xyoo).
3. so saum toj no
(1) Nco ntsoov xyuas seb lub qhov dej mesh npog ntawm lub twj tso kua mis submersible yog thaiv los ntawm cov nroj tsuag thiab av, thiab seb lub impeller puas yog entangled.
(2) Lub tshuab hluav taws xob submersible uas tsis tsim nyog rau lub sijhawm luv luv yuav tsum tau tsa rau ntawm qhov chaw nres nkoj, ntxuav thiab qhuav, thiab tom qab ntawd muab tso rau hauv qhov chaw qhuav thiab qhov cua.
(3) Tom qab lub tshuab hluav taws xob submersible tau khiav mus rau 1 mus rau 2 xyoos, lub cev muaj zog yuav tsum tau kuaj xyuas thiab ntxuav los ntawm cov tub ntxhais rub tawm. Yog tias muaj cov kab mob sib kis, muab tso rau hauv lub cev muaj zog hauv 0.2 feem pua Haiou TX-10 los yog 105 xab npum hmoov tov, ua kom sov rau li 100 degree thiab do cov kua kom maj mam yaj ntawm kev sib kis. Tom qab 1 ~ 2 teev ntawm kev kis kab mob, siv cov kais dej qis los tsim Pickled Zangjia los ntxuav cov tee dej, muab tso rau hauv qhov cub kom qhuav ntawm qhov kub thiab txias.
2. Kev tu cov twj submersible fais fab
Feem ntau faults, ua rau thiab kev daws teeb meem ntawm submersible electric twj
Rewinding ntawm lub cev muaj zog rotor windings
(1) Txhawm rau tiv thaiv lossis txo qhov tsis txaus ntseeg ntawm kev sib hloov ntawm lub rotor tshwm sim los ntawm qhov yuam kev disassembly, ua ntej sib dhos lub cev muaj zog, kos lub cim nrog lub accumulator ntawm qhov sib koom ua ke ntawm lub hauv ntej thiab nram qab kawg thiab lub hauv paus tshuab, thiab disassemble nws zoo li nws yog tom qab trimming.
(2) Thaum dismantling lub winding, xyuam xim tiv thaiv cov tub ntxhais hlau los tiv thaiv silicon wafer los ntawm kev nqa, hloov, thiab cov tsos ntawm burrs ntawm lub kaum sab xis. Txoj kev tshem tawm cov plooj zoo yog thawj zaug txiav lub kauj los ntawm ib kawg nrog kab pheeb ces kaum, thiab tom qab ntawd rub nws tawm nrog cov pliers ntawm lwm qhov kawg.
(3) Raws li qhov yuav tsum tau ua, lub kauj yog qhov txhab los ntawm lub tshuab cua tuag kom paub meej qhov kev tshem tawm sab nraud ntawm qhov kawg winding thiab cov kauj hauv qhov chaw.
(4) "txoj kev peb-dimensional" yog saws rau cov embedded hlau, uas yog, tom qab ib theem yog embedded, lwm theem yog embedded, thiaj li hais tias qhov kawg tsim ib "peb-txheej peb-dimensional": them sai sai rau thaum embedding: ① Thawj ob "daim tes tuav" coils Txoj hauj lwm yuav tsum tsim nyog los xyuas kom meej tias lub rotor core yuav tsis raug khawb thaum lwm cov coils yog embedded; ② Siv cov ntawv sau tsawg dua thaum siv cov kauj hauv qab, kom tsis txhob ua kom puas lub coil rwb thaiv tsev; ③ Cov ntawv insulating ntawm theem yuav tsum tau muab tso rau hauv qhov chaw, thiab ob-theem coils yuav tsum tau sab laug dav; ④ Hais txog cov roj Rau cov twj tso kua mis thiab dej puv, cov coils hauv qhov (nrog rau qhov xaus) tsis tuaj yeem compacted, kom cov roj (dej) tuaj yeem kho rau lub winding kom dissipate cua sov.
(5) daws qhov sib koom ua ke rwb thaiv tsev. Tshem tawm ntawm lub plhaub thiab txheej ntawm qhov sib koom ua ke, tshem tawm cov xim txheej thiab oxide txheej hauv lub npe ntawm tooj liab hlau; tom qab ntawd txuas ntxiv mus rau splicing thiab soldering, thiab tshem tawm cov ces kaum ntse, burrs thiab residual solder; Tom qab ntawd qhwv 2 txheej nrog polyethylene daim kab xev, Siv daim kab xev butyl self-adhesive stretched txog 2 zaug mus rau ib nrab-pawg 6 txheej (cov pob qij txha yuav tsum tau ceev faj thiab seamless), thiab pib siv polyethylene nplaum daim kab xev los yog polyester daim kab xev rau ib nrab-pem 2 txheej. raws li tus neeg kho tshuab npog.
(6) Khaws qias neeg thaum disassembled. Ua tib zoo kho qhov "limit screw" nyob rau hauv qab kom lub hau ntswj tig ywj siab, thiab ceev cov txiv ntoo xauv. Txhim kho lub hau kawg hauv nws txoj haujlwm qub, saib xyuas kom tsis txhob ua kom puas lub nplhaib roj hmab ntawm lub puab qhov ntawm lub thawv sealing. Thaum disassembling tag nrho lub cev sealing lub thawv, nws tsuas yog yuav tsum tau thawb me ntsis, thiaj li tsis mus khob.
3. Sim disassemble lub cev muaj zog
(1) Cua siab sim. Siv cov huab cua siab ntawm 2kg / mm2 los xyuas seb lub nplhaib "O" zoo li cov roj hmab sealing ntawm qhov sib koom ua ke ntawm tag nrho lub tshuab thiab ob phau ntawv zais cia hauv lub thawv ntim tag nrho lub cev yog breathable. Tom qab airtight, ntxiv txhua yam roj rau sab sauv thiab sab npog.
(2) DC tsis kam. Tus nqi tsis kam ntawm txhua theem winding ntawm lub rotor yuav tsum nyob rau hauv ± 2 feem pua kev ua yuam kev ntawm qhov nruab nrab tus nqi ntawm peb-theem winding kuj.
(3) Rwb thaiv tsev tsis kam. Yuav tsum yog> 5MΩ ntawm chav tsev kub.
(4) Mechanical xyuas. Thaum lub twj tso kua mis hluav taws xob khiav, lub suab ntawm txhua yam yuav tsum tau deformed.
(5) Shipboard sim. Lub nkoj nkoj DC tam sim no thiab lub nkoj poob hauv qab qhov hluav taws xob ntxiv tsis txawv ntau ntawm lub cev muaj zog. Lub 2.2kW submersible twj tso kua mis, uas tsis tshua muaj siv, muaj DC lub zog ntawm 1.8 ~ 2.5A, thiab qhov poob ntawm lub nkoj yog tsawg dua 0.5kW.
(6) Load sim. Tom qab khiav hauv dej rau 4 teev, qhov kub nce ntawm lub cev muaj zog tsawg dua lossis sib npaug li 75 degree.
(7) Kev sim nres. Khi lub impeller thiab txuas lub 100V theem pauv fais fab mov. Tus nqi DC ntawm txhua theem yuav tsum tsis pub dhau ± 10 feem pua kev ua yuam kev ntawm qhov nruab nrab tus nqi ntawm peb-theem DC.
