The water level in the water tower is maintained at a high level to ensure that sufficient cooling water is provided to the production facility.
The water level display of the conventional water tower is realized by converting a liquid level sensor into a current signal and connecting the current signal into a DCS (distributed control system) of a central control room to monitor the liquid level state of the DCS. Because the circulating water station is far away from the central control room, and people who are not in the central control room cannot easily enter the central control room, if the central control room staff find that the liquid level of the water tower is abnormal, the central control room staff need to inform the circulating water station staff of processing, the communication and processing timeliness is poor, and the circulating water station is only informed under the condition that the liquid level of the water tower is reduced under many conditions. Because the cooling water consumption is large, the time for fault treatment of the circulating water station is not sufficient.
When observing the liquid level of the water tower, the circulating water station worker generally judges that the liquid level of the water tower is in a high water level state through the overflow water condition of an overflow water pipe of the water tower. The overflow pipe is observed by manpower, so that time and labor are wasted, and the manpower is neglected. In summary, there is a greater safety risk of circulating cooling water.
