Abstract

The invention discloses an electrode type liquid level drainage control system and a control method. The system comprises a common terminal electrode bar, a low-liquid-level electrode bar and a high-liquid-level electrode bar. The common terminal electrode bar and the low-liquid-liquid electrode bar are equal in length and are both longer than the high-liquid-level electrode bar. The common terminal electrode bar, the low-liquid-level electrode bar and the high-liquid-level electrode bar are connected to a controller separately, the common terminal electrode bar and the low-liquid-level electrode bar are short-circuited when making contact with the liquid level and send signals to the controller, the controller outputs a control signal to control a water pump to start liquid level lowering, the common terminal electrode bar and the low-liquid-level electrode bar are open-circuited, and the controller can control working hours of the water pump through an adjustable resistor after the electrode bars are open-circuited. According to the system, a common terminal electrode bar, low-liquid-level electrode bar and high-liquid-level electrode bar combination scheme is adopted, and one-path ultra-high liquid level alarm of a two-path water pump or a one-path water pump can be controlled simultaneously.

Description

technical field [0001] The present disclosure relates to the technical field of drainage control, in particular to an electrode type liquid level drainage control system and a control method. Background technique [0002] At present, the electrode type liquid level drainage control is generally used in the drainage control system. Specifically, the electrode type liquid level drainage control generally uses the conductivity of the liquid to detect the level of the liquid level. It has a simple structure, easy to use, and is not limited by the installation environment. And other advantages, by installing electrode rods at different positions of low, middle and high in the rear lifting shaft, the low electrode rod is used as the common terminal, the middle electrode rod is used as the pump stop signal, and the high liquid level electrode rod is used as the pump start liquid level. [0003] The inventor found in actual work that the electrode rod conducts electricity and decomp...
