  • Peristaltic pump precise dosing control system and control method thereof
    Patent number: 11384744
    Abstract: A peristaltic pump precise dosing control system includes a driver, a pump head, pipeline switching means, a metering pipeline, and a discharge pipeline. An elastic tubing is provided in the pump head, and the outlet end of the elastic tubing is connected to the pipeline switching means. The driver drives the pump head to rotate to pump the liquid in the elastic tubing to the outlet end of the elastic tubing. The driver is electrically connected to the pipeline switching means so as to be capable of controlling the pipeline switching means to switch to the output pipeline with which the outlet end of the elastic tubing is connected. The pipeline switching means is driven to switch the outlet end of the elastic tubing from a state of connection with the discharge pipeline to a state of connection with the metering pipeline.
