The Henan Zhengzhou cooling tower: 1, standard design conditions: the Henan Zhengzhou cooling tower dry bulb temperature 31.5 ° C, wet bulb temperature of 28 ° C, atmospheric pressure 99400Pa, inlet temperature of 42 ° C, water temperature 32 ° C; stacked efficiently selection of the round tower dedicated filler class cooling pintada to compact structure, small footprint, the layout flexible design purpose; wing fasting structure of large diameter, large-area, low-speed, low dynamic pressure FRP fan blades, energy saving, low noise characteristics of the use of such cooling towers; 4, ultra-low noise cooling tower at the air inlet and outlet and the rain area set efficient noise reduction device, so that the same level of cooling tower effective noise reduction up to 5dB (A) ; 5, a large number of high-strength FRP structural components such the cooling towers Hishina cooling tower, it has excellent corrosion resistance, long service life of the obvious advantages; 6, the small rotary cooling tower water distribution system, the structure is simple, cloth water evenly, to further improve the thermal performance of the cooling tower, a large cooling tower the fixed water distribution system, further improve the stability of the tower; rotary water distribution system set the flap device, a fixed water distribution system set water collection device floating water losses are reduced to less than 0.01% of the cooling tower; 8, round tower structure itself, given its good performance of wind pressure, especially suitable for use in coastal typhoon region, such cooling tower design wind resistance of 0.75KN/m2 ; professional cooling tower, small size, light weight, simple structure, installation and maintenance extremely simple and convenient; Description: 1, the use of standard planetary gear reducer <72dB (A), the noise value of the standard point when using power with reducer the same low-noise cooling tower with an equal diameter. Listed in the table wet bulb temperature T = 28 ° C and T = 27 ° C cooling water, the conditions are as follows: When the temperature drop △ t = 10 ℃, the inlet water temperature t = 43 ° C water temperature T2 = 33 ° C. When the temperature drop △ t = 20 ℃ and 25 ℃, the inlet water temperature t1 respectively 60 and 55 ° C, t2 = 35 ° C water temperature] cooling tower manufacturers. 3, inlet pressure refers to the water pressure to take over at the point 1Kgf/cm2 = 9.8 × 104Pa, the tower water pressure in the series between 0.3 ~ 0.5Kgf/cm2
