Water leakage and over-temperature protector/B submersible pump, mixer, sewage pump integrated controller
1. Performance characteristics
/B series submersible pump/mixer integrated controller (hereinafter referred to as the controller), suitable for domestic production Protection and control of type submersible pumps and type B submersible mixers.
2. Principle
According to the structure and characteristics of the type submersible pump and type B submersible mixer working underwater for many years, it is necessary to add an oil chamber to the protection device of the type submersible pump and type B submersible mixer. Leakage protection and motor over-temperature protection and other functions:
Oil chamber leakage protection: A moisture detection electrode is placed in the oil chamber of the submersible motor. If there is moisture in the oil chamber, the electrode will have a signal jump, and the controller will A change in this signal is detected and the submersible motor is stopped and a fault is indicated.
Motor over-temperature protection: Install a ℃ C thermistor on each phase of the submersible three-phase motor winding. When the temperature of any phase winding rises to ℃, the resistance value will jump and the controller can detect this signal. changes, the submersible motor stops running and is indicated by a fault.
Motor overload protection: A thermal relay corresponding to the applied current is inserted in series on each phase line of the submersible three-phase motor operating circuit. Once the current is too large, the thermal relay will jump state, and the controller can detect the change of this signal. , and stops the submersible motor operation and indicates a fault.
Low water level protection: In a pool where the submersible motor is working, a liquid level detector is used to detect the water level.
But when the water level is lower than the water level where the submersible motor is working, the liquid level detector will jump and the controller will It can detect the change of this signal and stop the operation of the submersible motor and indicate the low water level.
