According to <
The maximum pressure rise of the volute (in front of the guide vane of water from the tubular unit) when the unit loses its charge. The rate guarantee value is selected according to the following different situations:
When the rated water height is less than 20m, it should be 70% to 100%.
When the design water height is 20-40 m, it should be 70-50%.
When the design water height is 40-100 m, it should be 50-30%.
When the design water height is 100-300 m, it should be 30-25%.
When the design water height is more than 300m, it should be less than 25% (reversible energy storage unit should be less than 30%).
The guaranteed value of the maximum pressure rise rate must be determinedbased on the calculated value with an appropriate margin.
Automatic rotary atomizing cooling tower achieves the purpose of reducing water temperature by eliminating latent heat of vaporization through heat conduction between circulating cooling water and cold, dry air and evaporation of circulating cooling water. The circulating cooling water with a certain pressure enters the cooling tower through the water inlet pipe, under the action of the swirling jet of the atomizer, it is atomized into mist with a diameter of 0 .1 mm and sprayed towards the top of the tower. The thrust generated by the jet causes the automatic rotation device to rotate, allowing the atomized water to fill the entire tower. The axial flow fan installed at the top of the tower rotates, forcing cold, dry air from the surrounding environment into the cooling tower through the window.re air inlet for mass and heat transfer with circulating cooling water. The flow of atomized water ejected from the atomizer flows very quickly and has ripple and drag effects, which generates a certain negative pressure around the atomizer, increases the air extraction volume and the cooling tower air inlet flow from the surroundings, and at the same time, the air flows upward, causing the cold, dry air to mix and come into more complete contact with the water mist (the air/water ratio can reach about 1.2). The particles in the atomized water stream are further refined. , and the diameter can be reduced to 0.01mm, and the air and water are fully mixed. The resulting mist stream is sprayed upwards towards the water collector installed at the top of the tower. The water is intercepted and returned to the cooling tower. the shape of a curtain of water. The heat of the air and wateru is evacuated from the tower by the water collector.
