Parallel waterway system and active control method for outlet water TDS

Abstract

The application discloses a parallel waterway system and a water outlet TDS active control method. The parallel waterway system comprises a first waterway, a second waterway and a mixed waterway. The first waterway and the second waterway are connected in parallel and then connected in series with the mixed waterway. The first waterway comprises a first water pump, an RO filtering device and a first water outlet end which are connected in sequence. The water outlet side of the first water pump is provided with a first pressure detection interface. The second waterway comprises a second water pump and a second water outlet end which are connected in sequence. The water outlet side of the second water pump is provided with a second pressure detection interface. The first water outlet end and the second water outlet end are combined and serve as the water inlet end of the mixed waterway. The water outlet end of the mixed waterway is a mixed water outlet end. The first pressure detection device is used to detect the water pressure P1 of the water outlet side of the first water pump, and the water pressure P1 is controlled to be within a preset first range. The second pressure detection device is used to detect the water pressure P2 of the water outlet side of the second water pump, and the water pressure P2 is controlled to be within a preset second range. The application can maintain stable and accurate mixed water outlet TDS values.
