According to customer feedback, our product models have been counterfeited and imitated by others for a long time. Due to poor consumer discrimination, it is easy to buy counterfeit products, which greatly affects consumers!
Our company decided to rename the LG-220V submersible pump leaking superheat protector, and rename it: KZ-LG submersible pump leaking superheat protector. Strengthen brand awareness! Prevent being deceived! At the same time, remind everyone to identify Kangzhuo trademarks when buying and beware of counterfeiting!
First, double-detection relay protector LG-220v for water pump leakage and overheating Introduction
(Leakage + overheating) The dual detection relay has the function of simultaneously detecting the leakage of the submersible pump and the overheating of the submersible pump.
① Submersible pump leakage protection function is used to detect whether there is water leakage in the submersible pump. When a water leak occurs in the pump, the control relay will send a corresponding control signal.
② The motor overheating protection function is specially used to detect the temperature of the stator coil in the submersible pump. When the stator in the pump body has abnormal temperature conditions, the control relay will send corresponding control signals. Workers perform timely maintenance on the pump. The control relay adopts a series of anti-interference measures in the circuit design, and can work reliably in the environment where the electromagnetic interference is very serious.
This type of relay is an alarm and control device that integrates leakage and overheating protection. In the system, it can monitor the performance of the pump in real time, and can simultaneously perform the protection and control functions of two parameters of the submersible pump.
The first function is that when the relay detects that the resistance value of the water sensitivity in the submersible pump is lower than the given value, the red indicator corresponding to the leak on the panel will light up, and at the same time, there will be a switch on the 7 and 8 feet of the relay output. Output, the relay continues to resume operation after power failure check 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 temperature of the stator coil of the submersible pump exceeds a given value, the red indicator light corresponding to the overheating on the relay panel will light up, and at the same time, the relay output terminal 7 and 8 will have a switching output. When the temperature drops, the relay continues to recover jobs. The given value of the resistance is standard, and can also be set according to requirements. Users with special needs must contact in advance.
