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. Rau cov roj-immersed submersible twj tso kua mis, xyuam xim rau kev puas tsuaj ntawm cov roj seepage ntawm lub twj tso kua mis hluav taws xob ntawm lub cable insulating roj hmab.
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 cov twj siv submersible, tus nqi ntawm cov dej yuav tsum tau kuaj ib hlis ib zaug, thiab nws yuav tsum tsawg dua 25ml, uas 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 tsis muaj roj, seb nws puas khiav ntawm lub nplhaib sab hauv lossis lub nplhaib sab nraud, thiab seb cov kabmob puas yuav tsum tau hloov pauv (cov kabmob ntawm lub twj tso kua mis uas muaj dej puv yog hloov ib xyoos ib zaug).
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 twj tso kua mis submersible uas tsis tsim nyog rau lub sijhawm luv luv yuav tsum tau muab tso rau hauv qhov chaw nres nkoj, ntxuav thiab qhuav, thiab khaws cia rau hauv qhov chaw qhuav thiab qhov cua.
(3) Tom qab QJ series submersible electric twj tso kua mis tau khiav mus rau 1 mus rau 2 xyoo, lub cev muaj zog yuav tsum tau mus txuas ntxiv mus xyuas thiab ntxuav los ntawm cov tub ntxhais rub. Yog tias muaj cov kab mob sib kis, muab tso rau hauv lub cev muaj zog hauv 0.2 feem pua Haiou TX-10 lossis 105 xab npum hmoov tov, ua kom sov rau li 100 degree thiab do cov kua kom qeeb cov kab mob 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.
