DFK-BF-3 sewage pump comprehensive protector

1. Overview
B sewage pump comprehensive protector is mainly suitable for the processing and conversion of sewage pump protection signals. It combines the sewage pump’s liquid level signal (switch signal), temperature signal (switch signal), water leakage signal (electrode signal) ) is converted into the contact signal output of the relay, which is convenient for use inside the sewage pump control cabinet.
2. Functions
B has three signal inputs, one of which is the liquid level signal input. It can only receive the switch level signal, and convert the small switch signal into a relay contact signal, which can be used for sewage discharge. The detection of leakage float signals in the upper cavity of the pump or the upper cavity can also be used for the conversion of other switching signals. The second channel is the over-temperature signal input, which can only receive switching over-temperature signals. For example, it is used to detect and convert the temperature signal of the upper bearing or lower bearing of the sewage pump. It can also be used to detect and convert the temperature signal of the sewage pump motor wire package. Convert. The third channel is the water leakage signal. It detects whether there is resistance between the electrode in the leakage chamber and the water pump shell (when the water pump leaks, the water first enters the leakage chamber. If the water leaks into the leakage chamber of the water pump, the leakage electrode is immersed, and the water leakage occurs. The relay will act and output a water leakage signal).
