The closed cooling tower is light in weight, simple in structure, reliable in operation and convenient in maintenance. Without motor and reducer, and without water injector, the tower is light in weight, simple in structure and easy to maintain. The following describes the noise treatment of the closed cooling tower when it is working:
The resistance of the closed cooling tower is reduced by 50%, and the fan motor saves 35% of electricity. The working pressure of the low-pressure atomization device is only 0.035 MPa, which is 0.17 MPa lower than the 0.2 MPa working pressure of the water pressure self-rotating atomization device, and the power of the supporting water pump is greatly reduced. The resistance of a closed cooling tower system without packing is about 1/2 of that of a packed tower. When the cooling water volume of the fan and the fan are the same, the power of the matching motor is reduced to 60% of the packed tower. The energy saving effect is remarkable. In addition, the cost of cleaning and replacing fillers and water distribution nozzles is eliminated, which greatly reduces operating costs.
1. The reducer is replaced with an ultra-low noise special type (imported ultra-low noise bearings), driven by Japan's Mitsubishi V-belt. Equipped with two layers of protective oil and two layers of waterproof system, good weather resistance, easy to maintain (just add butter). The driving wheel is replaced with a low-speed type, and the transmission part is inverted inside the air chamber, reducing the influence of tower noise.
2. The air duct only serves as an air guide, and will not be damaged by the load of the motor reducer and vibration fatigue. After damage, it will not affect the working environment of the transmission part due to aging or deformation, resulting in insufficient support rigidity of the transmission part and shortened service life. The upper device of the air duct is equipped with a diversion shielding tube designed according to the aerodynamic acoustic principle. Reasonable diversion angle can recover kinetic energy, reduce noise and hot steam backflow. The structure is composed of four integral parts, and the assembly is convenient and accurate. For details, please refer to the attached ram feature introduction.
3. The motor frame is positioned on the metal frame of the main beam at one time, with few parts, good rigidity, low vibration and no noise source.
4. The motor is a dedicated motor for totally enclosed cooling towers. A fully enclosed waterproof rubber pad is designed between the wiring closet and the fuselage. The shaft extension end is equipped with a waterproof rubber ring specially designed for the use environment of the cooling tower, which effectively solves the problem of water extending into the motor along the shaft. The motor shaft is chrome-plated, the protection class is IP55, the insulation class is b, and the motor has good waterproof performance, which can meet the special requirements of the closed cooling tower for the motor. The motor adopts vertical submersible installation with low noise.
