Kev Kho Txhua Hnub Thiab Kho Ntawm Qhov Zoo Tshaj Plaws Submersible Pumps

1. Hluav taws xob sab saum toj

(1) Nco ntsoov xyuas qhov ua haujlwm voltage thiab DC tam sim no ntawm lub twj tso kua mis submersible. Qhov peb-theem voltage ntsuas los ntawm lub ntsuas dej siab yuav tsum yog qhov sib koom ua ke, thiab ntawm 340 ~ 420V, peb-theem DC tam sim no ntsuas los ntawm clamp-hom DC meter yuav tsum yog 0.5 ~ 1 zaug ntawm qhov ntxiv. ncaj qha voltage. Tam sim no.

(2) Tsis tu ncua xyuas cov thermal rwb thaiv tsev ua haujlwm ntawm lub twj tso kua mis submersible rau hauv av. Tom qab lub malformation tseem khiav mus rau 4 ~ 6h, lub megohmmeter ntawm lub cev muaj zog winding yuav tsum tau siv los ntsuas lub rwb thaiv tsev tsis kam ntawm lub cev muaj zog winding rau hauv av > 0.5MΩ. Rau lub neej luv luv submersible twj, lawv yuav tsum tau kuaj xyuas ua ntej siv.

(3) Ua ntej pib lub tshuab, koj yuav tsum kuaj xyuas qhov tseeb ntawm cov khoom siv hluav taws xob thiab seb qhov seem ntawm qhov kev teeb tsa ua haujlwm puas yog deformed.

(4) Xyuas seb lub cable puas puas lawm. Rau cov roj-immersed submersible twj, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau qhov kev puas tsuaj ntawm cov kab hluav taws xob rwb thaiv tsev roj hmab los ntawm cov roj to.

2. Mechanical sab saum toj

(1) Ib txwm tshuaj xyuas cov tshuab ntsaws ruaj ruaj ntawm cov twj submersible. Qhib cov roj qhov ntsia hlau thiab tso cov roj ntau ntau. Yog hais tias cov roj muaj dej, nws yog ib qho cim qhia tias lub sab sauv abrasive block (los yog qis abrasive block) foob muaj dej oozing. Hloov lub thawv kaw thiab tshem tawm cov roj icing tshiab. Yog tias tsis muaj cov roj hauv cov 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) lossis roj tshiab.

(2) Rau cov twj tshiab lossis hloov cov twj submersible nrog cov kev sib tsoo, tom qab 50 teev ntawm kev siv, cov dej foob yuav tsum raug tshem tawm, thiab cov roj (dej) yuav tsum tau kuaj xyuas.<5ml indicates a malformed seal. If used, if 5ml is >, oil will be used. After (water) is tightened, tighten the plug tightly and continue to use for 50 hours for a second inspection. If 5m1 is still >, nws qhia tias muaj teeb meem nrog lub foob. Hais txog cov twj siv submersible, tus nqi tshaj tawm yuav tsum tau kuaj ib hlis ib zaug thiab yuav tsum tsawg dua 25 ml.

(3) Tshawb xyuas qhov kev vibration ntawm lub twj tso kua mis lub cev muaj zog. Lub synchronization ceev yog n0=3000r/min, 1500r/min, 1000r/min, 750r/min. Cov nqi vibration yog δ Tsawg dua lossis sib npaug li 0.06mm, 0.1mm, 0.13mm, 0.16. millimeter.

(4) Tsis tu ncua xyuas cov kabmob ntawm lub twj tso kua mis submersible. Xyuas seb cov kabmob tsis muaj roj, seb puas muaj lub nplhaib sab hauv khiav lossis lub nplhaib sab nraud khiav, thiab seb cov kabmob yuav tsum tau hloov li cas (cov kabmob ntawm lub twj tso kua mis muaj dej yuav tsum tau hloov ib xyoos ib zaug).

3. Qhov seem ntawm cov saum toj no

(1) Nco ntsoov xyuas seb lub tshuab nqus cua ntawm lub twj tso kua mis submersible yog thaiv los ntawm cov nroj tsuag thiab seb lub impeller puas yog entangled.

(2) Cov twj siv hluav taws xob submersible uas tsis xav tau rau kev ua haujlwm luv luv yuav tsum tau tsa ntawm qhov chaw nres nkoj.

(3) Tom qab 1 mus rau 2 xyoos ntawm kev ua haujlwm ntawm lub twj tso kua mis submersible, kev tshuaj xyuas tseem ceeb thiab kev tu lub cev yuav tsum txuas ntxiv mus. Yog tias muaj kev ua qias tuaj, lub cev muaj zog tuaj yeem muab tso rau hauv 0.2% HaijinTX-10 lossis 105 xab npum hmoov tov, rhuab mus txog 100 degree thiab nplawm kom yaj cov kua kom qeeb cov pa phem, tom qab ntawd 1 ~ 2h ntawm cov pa phem, tom qab ntawd siv cov kais dej uas tsis tshua muaj siab los ua cov cuab yeej marinate thiab muab cov dej tso rau hauv qhov cub thiab qhuav ntawm qhov kub thiab txias.
