Wet motor pump and wet motor

摘要

Problem to be solved: to provide a wet motor pump and a wet motor capable of improving the accuracy of the predictive maintenance and reducing the risk of failure due to trouble in the electric circuit.A pump 1 disposed in a liquid and sucks and discharges the liquidAn underwater motor 2 which is filled with the liquid and is disposed in the liquid and drives the pumpSensors 2ja to 2jf installed in the underwater motorSensors 22-2kf transfer signals from 2kA to 2kfThe underwater motor 2 is provided with a power line 3 serving as an electric wire for power distribution.The communication lines 2kA to 2kf are connected to the power line 3 within the underwater motor 2.Diagram
