Description

Technical Field

[0001] The utility model belongs to the technical field of cooling equipment, and particularly relates to a water level balancing device for water collecting tanks of multiple cooling towers. Background Art

[0002] In the cooling system, multiple cooling towers are usually used in parallel operation to achieve the cooling effect of cooling water for equipment such as refrigerators and air compressors. When multiple cooling tower outlet pipes are connected in parallel to a water outlet main pipe, each cooling tower is equipped with a separate water supply pipe, and the float valve controls the water supply amount according to the water level of the water collection tank. In the absence of a water collection tank, the tower far away from the water pump group has greater resistance along the way than the tower near the water pump group. Under the same water inlet, the water in the water collection tank of the tower far away from the water pump group will be sucked away less, and the water collection tank will overflow, while the water in the water collection tank of the tower near the water pump group will be sucked away more, and the water collection tank will be dry. The float valve will be fully opened to continuously replenish water, causing a waste of water resources; when the cooling tower water supply pump needs to be repaired and the water pump is switched, the water level of the water collection tank will be unbalanced due to the change in the water pump flow; when the cooling tower cooling fan needs to be repaired and the fan is switched, the water level of the water collection tank will be unbalanced due to the change in evaporation; operations such as increasing or decreasing the number of cooling towers in operation and switching cooling towers will affect the water level of the water collection tank. In all the above situations, the cooling tower's water inlet and outlet pipes need to be readjusted to maintain the water level, and repeated adjustments are required to find the balance point.
