Kā lietot lietot digitālais multimetrs to izmērīt kvalitāte of 220 Iegremdējamais sūknis
1. Check for leakage
Ūdens sūknis ir noplūde un nevar ir lietot at all. Even if it var būt tikko lietots, tur ir joprojām pārāk daudz drošība apdraudējumi. Set the digital meter to the maximum resistance position, measure the power plug to the water pump corping, and check if there is at {{{{0}}}.5 megohm of izolācija pretestība. The higher the resistance value, the better. If the pretestība vērtība ir lielāks nekā vai vienāds līdz 0.5 megohm, tur ir būtībā nav noplūde. Ja skaitlis rāda nulle, it norāda nopietna noplūde un tur ir a zemējums defekts.
Atvērt vāks un pārbaudīt ja tur ir jebkurš bojājums vai sadursme ar apvalku on ienākošo vadu . Ja tur ir nav bojājums , lūdzu sazinieties ar motoru apkopi tehniķis to atrisināt problēmu.
2. Pārbaude spole
If there is no leakage, start this step and measure whether the power plug is connected on the 2k gear of the digital meter. If it is not connected, confirm that the coil is burnt out or disconnected for some reason, and ask the maintenance technician to handle it.
If the live wire of the plug is measured and the zero wire is connected, then there is no problem. If it's too troublesome, you can plug in and test the machine. If it still doesn't work, remove the water pump cover and measure whether the three wires meet the resistance relationship of rCR plus rCS=rRS. That is, the resistance relationship between the public end% 2c startup end, and running end.
As long as the resistance relationship is met and there is no leakage, the water pump is basic good. If the next test drive still does not start, then it is need to check if it is stuck.
