Water pump motor is divided into two kinds, including submersible pump motor and ordinary water pump motor. Submersible pump motor have waterproof function, and ordinary water pump does not have waterproof function, easy to burn out after the water.
Ordinary water pump in water. What should I do?
A, motor shells into the water, if the insulation is normal, electric trouble-free, after the motor shell to dry or dry naturally.
Second, the motor water flooded or motor bearing, shall be immediately shut down the motor, power off, and remove the motor power wiring. Maintenance personnel will first motor system.its locked-rotor, with a clean cloth to wipe clean, then the motor bearing lubricating oil clean with gasoline or kerosene, and after drying treatment to add lubricant. Electrical maintenance personnel in the first place before and after the demolition of motor end cover inspection motor terminal box, if there is water used cloth to wipe clean. With baking box or a large light bulb to dry processing of motor stator winding, dry after a period of time with shaking table or a universal measure of motor insulation board, insulation resistance must be greater than 0.5 ohms. Connect the power cord, the ends motor cover, screw down the screws. Dish with the hand move flexible rotor motor installation is completed, no jamming servicing mission ends.
Electrical operation personnel shake measured motor stator winding insulation to ground and alternate with qualified after sending the related, observe motor three-phase voltage, no-load current is normal, motor without a sound, vibration in the normal range. When running 30 minutes without exception can be as backup.
After three, motor into the water, if after the drying process of motor stator coil insulation low still cannot meet the requirements, should be winding of the stator coil and offline processing, measuring insulation for start-up after normal. If you run after 30 minutes without exception can be as backup. |
