>1. Performance characteristics
> Type submersible pump protector (hereinafter referred to as the protector), mainly monitors the temperature of the stator winding of the submersible pump and the leakage of the sealing cavity of the water pump , suitable for the protection and control of lifting pump r, return pump r, agitator r, propeller r, and sewage pump r. It can be applied to Hydro (>r), Nanjing Beite, Shanghai Chuanyuan, Lanshen Group, Yangzijiang Pump Industry, Nanjing Brooklyn or other similar submersible pumps. There are also models that provide direct monitoring of critical motor bearing temperatures.
>2. Principle
>
This type of monitoring and protection device monitors motor overheating and seal leakage, thereby greatly reducing the possibility of costly forced outages. If the temperature of the motor reaches a preset temperature or water enters the sealing chamber, the sensor can be set to alarm or shut down the water pump operation to notify maintenance personnel for preventive maintenance. It can also be set to disable the device and sound on the temperature. or water intrusion alarm.
>
Leakage> Protection: A moisture detection electrode is placed in the oil chamber of the diving protector. If there is moisture in the oil chamber and the signal jumps when the water exceeds the limit, the protector can Changes in this signal are detected to indicate a fault or disable the device.
>
Winding> ( ) protection: Install a temperature detection sensor on each phase of the three-phase motor winding of the submersible mixer. When the temperature of any phase winding rises abnormally, the protector can detect Changes in this signal indicate a fault or disable the device.
