Model: KZ LG submersible pump leakage protection and overheating protector
I. Brief Introduction of Leakage Protection and Overheating Protection of Submersible Pump
KZ-LG submersible pump leakage protection and overheating protector are designed and produced by Kangzhuo meter, which has the function of detecting submersible pump leakage and overheating at the same time.
① The submersible pump leakage protection function is used to detect whether the submersible pump leaks water. When the water pump leaks, the control relay will send out corresponding control signals.
② The motor overheat protection function is specially used to detect the temperature of the stator coil of submersible pump. When the stator temperature in the pump body is abnormal, the control relay will send out corresponding control signals. The staff repaired the water pump in time. The control relay has adopted a series of anti-interference measures in the circuit design, which can work reliably in the environment with serious electromagnetic interference.
KZ-LG submersible pump leakage protection and overheating protector are independently developed and obtained national patents, and are designated models by many domestic design institutes!
Second, the leakage protection and overheating protector function of KZ-LG submersible pump
The leakage protection and overheating protection of KZ LG submersible pump are alarm and control equipment integrating leakage protection and overheating protection. In this system, the performance of pump can be monitored in real time, and two parameters of submersible pump can be protected and controlled at the same time.
The first function is that when the relay detects that the resistance value of the water sensor in the submersible pump is lower than a given value, the red indicator light corresponding to the leakage on the panel will light up, and at the same time, the relay output terminals 7 and 8 will have switch outputs, and the relay will continue to work after power failure inspection and troubleshooting.
The second function is also used to detect the temperature of the stator coil inside the submersible pump. When it is detected that the stator coil temperature of submersible pump exceeds a given value, the red indicator light corresponding to overheating on the relay panel will light up, and at the same time, the relay output terminals 7 and 8 will have switch outputs. When the temperature drops, the relay will continue to work. The given value of the resistance value is standard and can be set as required. Users must contact in advance if they have special needs.
