3. Especially, in winter, the temperature is below zero, circulating water is heated and flows after passing through cooling equipment, so that the water temperature of the whole cooling tower is increased, the situations that a water source is frozen and a system pipeline valve is damaged due to low-temperature freezing do not exist in the fire-fighting water system, and the reliability of the fire-fighting water system is effectively ensured.
4. The fire-fighting water system adopts full-automatic control, and concretely comprises the following steps: (1) the automatic water replenishing pump can automatically replenish water according to the water level of the high-level water tank; (2) the stabilizing pump can be continuously started and stopped according to the pressure of the fire-fighting water pipeline, and the water supply pressure of the fire-fighting water pipeline is kept; (3) the fire pump can automatically start according to the flow speed and the pressure of the fire water pipeline; thereby ensuring the reliability of the fire-fighting water system.
5. The cooling tower and the high-level water tank share a water source, the number of monitoring personnel and inspection personnel is reduced, and labor cost and construction cost are saved.
