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 LB-220V submersible pump leak protector to KZ-LB submersible pump leak protector. Strengthen brand awareness! Prevent being deceived! At the same time, remind everyone to identify Kangzhuo trademarks when buying and beware of counterfeiting!
First, the introduction of detection relay
The submersible pump leakage protection relay is a resistor specifically used to detect the sensitivity of water in the submersible pump. The sensor uses an electrode sensor. When a water leak occurs in the pump body, the control relay will send a corresponding control signal so that the staff can deal with the water leak in the pump. The controller has adopted a series of anti-interference measures on the line design, and can work reliably in the environment with very serious electromagnetic interference.
The detection relay uses a signal from the water sensitive resistor sensor to determine whether there is water leakage in the cavity of the submersible pump; that is, the water sensitive resistor sensor detects the resistance to ground in the cavity. If it is lower than the controller set value, the relay will act. The red indicator light on the panel lights up. At the same time, the terminals 5, 6, 7, and 8 of the controller output a set of switching signals to cut off the main control circuit of the submersible pump; and output a set of passive switching signals to effectively protect the diving. The pump can only be operated under safety conditions. If the controller is reset automatically after the fault is removed, the pump can continue to run. The given value of the resistance is standard, and can also be set according to requirements. Users with special needs must contact in advance.
