Lub twj tso kua mis submersible kuj yog ib hom twj tso kua mis siv hauv cov khoom siv dej. Nws cov kev ua txhaum ntau thiab kev saib xyuas yog raws li hauv qab no:
1. Lub twj tso kua mis pib tsis tau
Yog vim li cas: Lub hwj chim mov voltage tsawg dhau; Muaj ib qho kev tawg ntawm qhov chaw hauv Circuit Court; Lub twj tso kua mis impeller yog daig los ntawm cov khoom txawv teb chaws; Cable tawg; Qhov hluav taws xob poob ntawm lub cable yog siab dhau lawm, thiab lub ntsaws cable puas lawm; Ib theem ntawm peb -theem cable tsis txuas; Lub winding nyob rau hauv lub cev muaj zog chav yog burnt tawm.
Exclusion method: Kho qhov voltage rau 342V ~ 418V; Txheeb xyuas qhov ua rau lub zog hluav taws xob thiab tshem tawm; Tshem tawm daim ntawv qhia thiab tshem tawm cov khib nyiab; Hloov raws li cov lus qhia cable; Siv cov cables tuab dua; Hloov lub ntsaws tshiab, kos lub qhov hluav taws xob hloov thiab cable; Overhaul lub tshuab hluav taws xob.
2. Lub twj tso kua mis tsis tsim cov dej tom qab pib, tsim cov dej me me los yog tsis sib xws
Yog vim li cas: Lub tshuab hluav taws xob tsis tuaj yeem pib; Cov kav dej thaiv; Pipeline rupture; Lub lim dej yog thaiv; Qhov chaw suction yog nthuav tawm saum npoo dej; Rov qab tig ntawm lub cev muaj zog, kev puas tsuaj rau lub twj tso kua mis casing sealing nplhaib thiab impeller; Lub taub hau tshaj lub taub hau ntawm lub twj tso kua mis submersible ntau dhau; Lub impeller tig rov qab.
Txoj kev daws teeb meem: tshem tawm cov teeb meem hauv Circuit Court; Tshem cov blockages; Kho vuam lossis hloov cov kav dej; Tshem cov blockages; Rov nruab; Hloov txoj haujlwm ntawm cov hlua hluav taws xob; Hloov nrog qhov tshiab; Hloov lub taub hau siab; Rov nruab.
3. Lub tshuab hluav taws xob tsis tuaj yeem pib thiab muaj suab nrov
Yog vim li cas: Ib qho ntawm cov theem yog qhib Circuit Court; Bearing tuav ncej; Muaj cov khoom txawv teb chaws nyob rau hauv lub impeller thiab lub twj tso kua mis lub cev yog daig.
Txoj kev cais tawm: kho lub voj voog; Kho lossis hloov cov kabmob; Tshem tawm cov khoom txawv teb chaws.
4. Sudden interruption ntawm lub twj tso kua dej tso zis thiab lub cev muaj zog kaw
Yog vim li cas: Cua hloov pauv los yog fuse cua tshuab, hluav taws xob poob; Lub stator winding yog hlawv tawm; Impeller daig; Dej tsis txaus nyob rau hauv ntub submersible twj tso kua mis lub cev muaj zog; Lub cev muaj zog ntawm cov roj puv ntub dej submersible twj tso kua mis yog luv ntawm cov roj.
Txoj kev daws teeb meem: Tshawb xyuas qhov tsis raug ntawm Circuit Court, lub cev muaj zog winding faults, thiab tshem tawm lawv; Tshawb xyuas qhov ua rau lub zog hluav taws xob thiab tshem tawm qhov txhaum; Kho lub stator winding; Tshem tawm clutter; Kho lub cev muaj zog.
