Lub twj tso kua mis submersible tau siv dav hauv cov dej tob tob. Cia peb tham txog nws txoj kev tu thiab kev tiv thaiv txhua hnub.
1. Hluav taws xob sab saum toj
(1) ib txwm tshuaj xyuas qhov ua haujlwm voltage thiab DC tam sim no ntawm lub twj tso kua mis submersible. Qhov peb-theem voltage ntsuas los ntawm qhov ntsuas dej siab yuav tsum yog qhov sib koom ua ke. Thaum 340 ~ 420v, lub clamp hom DC meter yuav tsum tau siv los ntsuas peb-theem DC tam sim no, uas yuav tsum yog 0.5 ~ 1 npaug ntawm qhov hluav taws xob ncaj qha ntxiv. Tam sim no.
(2) regularly check the thermal insulation performance of submersible pump to the ground. After the motor continues to operate for 4 ~ 6h, the megger of the motor winding shall be used to measure the insulation resistance of the motor winding to the ground >0.5m Ω. Lub twj tso kua mis submersible nrog lub neej luv luv yuav tsum tau kuaj xyuas ua ntej siv.
(3) ua ntej pib lub tshuab, nws yog ib qho tsim nyog los xyuas qhov meej ntawm cov khoom siv hluav taws xob thiab seb qhov seem ntawm cov kev teeb tsa ua haujlwm puas yog deformed.
(4) xyuas seb lub cable puas puas lawm. Rau cov roj immersed submersible twj, yuav tsum tau them nyiaj rau kev puas tsuaj ntawm cable rwb thaiv tsev roj hmab los ntawm cov roj to.
2. Mechanical sab saum toj
(1) feem ntau tshuaj xyuas lub tshuab foob ntawm lub twj tso kua mis submersible. Qhib cov roj qhov ntsia hlau kom tso cov roj ntau ntau. Yog hais tias cov roj muaj dej, nws qhia tau hais tias lub sab sauv sib tsoo block (los yog qis sib tsoo block) foob tau exuded dej. Hloov lub thawv ntim khoom thiab tshem tawm cov roj khov tshiab. Yog tias tsis muaj cov roj hauv cov roj los yog cov roj tsis zoo, muab cov roj (No. 5 los yog No. 10 mechanical oil, sewing oil or transformer oil) los yog roj tshiab.
(2) rau cov twj submersible nrog cov tshiab lossis hloov cov kev sib tsoo, tom qab 50 teev ntawm kev siv, tshem tawm cov dej foob ntsaws thiab xyuas cov roj (dej)< 5ml="" indicates="" abnormal="" sealing.="" if="" used,="" if=""> 5ml, oil will be used. (water) after tightening, tighten the sealing plug tightly and continue to use it for 50 hours for the second inspection. If still >5m1, muaj teeb meem nrog lub foob. Rau cov twj siv submersible, qhov nthuav tawm yuav tsum tau kuaj ib hlis ib zaug, uas yuav tsum tsawg dua 25ml.
(3) 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 thiab 750r / min. Vibration tus nqi yog δ Tsawg dua lossis sib npaug li 0.06mm, 0.1mm, 0.13mm, 0.16. Mm.
(4) tsis tu ncua xyuas cov kabmob ntawm cov twj tso kua mis submersible. Xyuas seb cov kabmob puas yog luv luv ntawm cov roj, seb puas muaj lub nplhaib sab hauv lossis lub nplhaib sab nraud, thiab seb cov kabmob yuav tsum tau hloov li cas (nws yog qhov zoo tshaj los hloov cov kabmob ntawm cov dej filling fais fab ib xyoos ib zaug).
3. Qhov seem ntawm sab saum toj
(1) nco ntsoov xyuas seb lub hau npog ntawm lub twj tso kua mis submersible yog thaiv los ntawm cov nroj tsuag thiab seb lub impeller puas raug mob ua ke.
(2) cov twj submersible tsis tas yuav tsum tau ua haujlwm luv luv yuav tsum tau tsa ntawm qhov chaw nres nkoj.
(3) tom qab lub twj tso kua mis submersible tau ua haujlwm rau 1 ~ 2 xyoos, kev tshuaj xyuas tseem ceeb thiab kev tu lub cev yuav tsum txuas ntxiv mus. Yog tias muaj kev ua qias tuaj, muab lub cev tso rau hauv 0.2 feem pua haijintx-10 lossis 105 xab npum hmoov, ua kom sov rau li 100 degree C thiab do cov kua yaj kom qeeb cov pa phem. Tom qab 1 ~ 2H ntawm cov pa phem, marinate lub armor nrog tsawg-siab kais dej, muab cov dej tee tso rau hauv qhov cub thiab qhuav ntawm qhov kub thiab txias.
