The present disclosure exemplarily describes the operation of the sump automatic drain, for example, by using a mechanical detection mechanism in combination with the drop-in level sensor 7 to determine the water level in the sump 11. Wherein, the upper limit value and the lower limit value of the liquid level in the water pit can be preset through the controller.
When the mechanical detection mechanism and the input liquid level sensor 7 are used normally, the liquid levels detected by the mechanical detection mechanism and the input liquid level sensor are basically consistent. Thus, when the liquid level in the sump 11 is higher than the upper limit value, the mechanical detection means and the input liquid level sensor 7 can both detect that the current liquid level is higher than the upper limit value, and at this time, the control device 1 controls the drain means to start operating. When the liquid level in the sump 11 is lower than the lower limit value, the mechanical detection mechanism and the input liquid level sensor 7 can both detect that the current liquid level is lower than the lower limit value, and at this time, the control device 1 controls the drainage mechanism to stop working.
When one of the mechanical detection mechanism and the input liquid level sensor 7 is damaged or fails and the other is used normally, the liquid levels detected by the mechanical detection mechanism and the input liquid level sensor are inconsistent, an alarm mechanism can be triggered to alarm at the moment, and related technicians are notified to overhaul.
During the alarm, when one of the mechanical detection mechanism and the drop-in level sensor 7 detects that the current level is higher than the upper limit value and the other one does not detect that the current level is higher than the upper limit value, the control device 1 can control the drainage mechanism to start working for safety. Wherein it is possible to determine which of the two is failed or damaged by whether or not the liquid level detected by both the mechanical detection mechanism and the throw-in liquid level sensor 7 has found a change. In addition, after the signal that the detected liquid level is higher than the upper limit value has disappeared, which means that the liquid level is already lower than the upper limit value at this time, the control device 1 may select to control the drain mechanism to stop operating. When the detected signal of the liquid level higher than the upper limit value continuously exists or does not disappear, for example, when another liquid level detection signal continuously changes, the drainage mechanism can be stopped, and then the current liquid level can be judged not to be higher than the upper limit value.
In addition, when the staff overhauls, can also be through opening drainage mechanism and observe the liquid level change that above-mentioned two detected and judge which one is out of order or damaged.
