Zusammenfassung: | A liquid medicament automatic adding device includes a high-level drug box and a drug storage box which communicate through a feed pipe; the lower part of the drug storage box is provided with a discharge pipe, the discharge pipe is provided with a calibration valve and an electromagnetic valve, the electromagnetic valve is connected with a relay, and the relay is connected with the output end of a controller, and the input end of the controller is connected with a touch screen. A control method comprises the steps: firstly, setting the flow quantity per unit time a and the liquid maximum flow quantity per unit time x, and transmitting the signals to the controller; calculating the ratio a/x=b of the set flow quantity a and the calibration maximum flow quantity x, converting the b into the time with the second as the unit: 60*b=t(s), then making the energization time of the electromagnetic valve at each time be t/T(s), and then transmitting the result signal to the relay; and controlling the medicament adding |
