The role of the cooling tower, cooling towers, pumps, quality and excellence

Cooling tower principle: cooling tower water is generally heat by natural cooling, so they requested that the volume and surface area of ??the cooling tower heat sink is large enough. If the ambient temperature is too high, such as to reach above 40 ℃, the cooling towers of the cooling water temperature will be higher, thereby reducing the heat transfer capacity, so that oil can not be cooled pressing machine. To ensure that the temperature of hot press balance can be taken continuously or intermittently added to cold water cooling tower method. The main factors that affect the heat transfer effect of: cooling towers, the water forms a water film or droplets in the filler, the filler surface in direct contact with the process air, simultaneous heat and mass transfer; heat transfer due to the temperature difference between water and air, The mass transfer due to the surface water formed by evaporation of water vapor into the air constantly diffusion of the cooling tower, while the vapor of the heat into the air, the heat and mass transfer processes, water cooling process is called evaporative cooling process Therefore water in evaporative cooling process of the heat is composed of two parts, namely the contact heat (conduction and convection) and evaporative cooling. The main factors affecting the heat transfer effect: the use of cooling towers purpose is to achieve a certain cooling effect, which mainly depends on the heat sink, fan air flow, cooling tower water use, and good ventilation, installation location also has a certain impact. Fin: the key components of the cooling tower, mini tower generally use PVC sheet pressing or hot-priming, large tower will use wood, the main purpose of the air and water contact surface does not affect the drag cooling tower pump manufacturers, the more large as possible, while the heat exchange rate reached a maximum of two parameters, the effect of heat transfer fins affect mainly fin shape and height, during the cooling tower installation, try not to damage the heat sink fins to prevent the water does not flow. Fan flow: a major role in accelerating the air flow cooling towers, accelerate the heat exchange air and water to remove heat. The main factors affecting the amount of wind turbine blade shape is that the length and width of the blades themselves declination, fan speed, installation angle, speed and motor and gear ratio. Further, in the case where the same amount of wind, the same type of tower, cooling water is smaller than the large amount of cooling water cooling effect is better. Main products: cold 塔嘉 Huzhou Hing cooling tower must exist certain "surplus energy by 20% -25%" Wujiang cooling tower cooling towers 1. Hangzhou cooling tower circulating water system at run time to put these energy gathered in a valve office, over time these energies will be lost in vain. External turbine is to use these "surplus energy" is converted to mechanical energy efficient, thus 100% replace cooling tower fan motors achieve energy-saving purpose. 2. How critical external motor-driven turbine efficiency can be achieved are: Understanding the cooling tower circulating water system design surplus energy, while the turbine impeller design is also key, surplus energy is mainly composed of the following six sections: 1) circulating water system design must be considered when more than money; potential use 2) heat transfer equipment; 3) the ability to regulate the turbine itself; 4) water circulation system converts kinetic energy efficiency; 5) in place when the valve is not open, consumed by the valve energy. 6) low flow through the shunt method merge again to meet system requirements. 3. energy-saving cooling tower between old tower cooling tower and heat transfer equipment, driven by a pump to circulate the cooling tower pumps offer, external pressure turbine backwater can use to convert the drive turbines for power driven fan, generally in accordance with three cooling towers make energy-saving, the design flow is too large at about 60% of the actual amount of cooling towers, pumps, taking into account changes in production requirements, energy-saving method is: two Cupola for turbine driving a motor driven Cupola spare time in the summer, work 4. schematic external cooling tower turbine tower design new work focuses backwater backwater pressure or flow to meet the turbine as a function of force to drive fans, the law of conservation of energy - how much return flow or pressure transducer fan speed =. External turbine speed according to changes in the system and increase or decrease the flow of the system of three external cooling tower turbine, turbine outlet through three towers, adjust the flow through the bypass valve and ease of maintenance.
