Submersible pump comprehensive protector, one-control two-water pump protector, leakage protector
1. Introduction:
This series of products is the company's protection application for small submersible sewage pumps in water supply, drainage and sewage discharge. And a series of products developed and produced. Mainly used in garages, basements, hotels, restrooms and other public places. This series of products is cost-effective, full-featured, and has many product models, including two main specifications: (one controls one) and (one controls two). >
2. Working principle: >
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, There is a signal jump in the electrode, and the controller can detect the change of this signal, stop the operation of the submersible motor and indicate a fault. >
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 ℃[forbidden word], the resistance value will jump. change, the controller can detect the change of this signal, stop the operation of the submersible motor and indicate a fault. >
Motor overload protection: In the operating circuit of the submersible three-phase motor, a thermal relay corresponding to the applied current is connected in series to each phase line. Once the current is too large, the thermal relay will jump in state, and the controller can detect When this signal changes, the submersible motor stops and a fault is indicated.
B submersible pump comprehensive protector (one control, two), the pump protection signal includes water leakage protection, overheating protection, overload protection, etc. >
