From the design to the use of the closed cooling tower, it needs to go through many processes to ensure that it can play its due role and maximize its benefits. The first is design and preparation, and the second is fluent assembly, including assembling the tower body, installing the sprinkler system, installing the circulating pump, installing the water tank and water treatment equipment, fittings such as pipe connections and valves, as well as hydraulic testing and no-load commissioning, etc. step.
During the assembly process, it is necessary to operate in strict accordance with the instructions or drawings, pay attention to safety matters, and ensure that all components and equipment comply with relevant standards and regulations. Testing and commissioning are critical steps in ensuring the proper functioning of your fluid cooler. Through correct assembly and commissioning, the closed circuit cooling tower can provide effective heat exchange and cooling effect to meet the requirements of industrial production.
Assembly process of closed cooling tower
First, design and preparation.
During the design and preparation stages, the specification, performance and functional requirements of the fluid cooler need to be considered. Usually, this requires the use of professional software for detailed design and calculation, selection of suitable materials and components, consideration of field use conditions, full efficiency, sufficient power, and extended service life. To ensure that the assembly goes smoothly, it is also necessary to have all the necessary tools and equipment ready.
Second, assemble the tower body
The tower body is the core part of the closed cooling tower, including heat exchange coils and internal frames, equipment shells, filler and sprinkler systems, wind systems, etc. Usually, the steel frame is divided into several modules, and each module includes multiple bolts and connectors. The fasteners in key parts are made of 304 material to ensure that they will not rust for a long time, which not only prolongs the service life, but also ensures smooth maintenance. During assembly, the modules should be installed and tightened one by one to ensure that the tower structure is strong and stable.
Third, install the sprinkler system
The sprinkler system is used to evenly spray spray water on the heat exchange coil. Usually, the sprinkler system consists of spray pumps, pipes, and nozzles. The choice of the spray pump is the design leader. Its choice must first meet the flow requirements. It is a key consideration in software calculation and coil design. It can not only meet the evaporation requirements, but also not increase the thickness of the water film and reduce the heat of the pipe wall. resistance. Secondly, under the premise of overcoming the resistance and satisfying the water pressure of the nozzle, the head should be reduced as much as possible to save the power consumption of operation. Finally, in terms of details such as nozzle structure, nozzle connection and pipe inner wall smoothness, it is considered from the perspective of users such as maintenance, life and energy saving.
Fourth, install the circulation pump
The circulating pump is the source of power to drive the flow of the internal circulating water, and the source of power to ensure the progress of the internal circulating water during cooling and cooling. The basic parameters are flow rate and head, and the energy consumption of operation is reflected in power, which is the main index of energy level. During the design of Oasis Bingfeng, detailed calculations are made based on the user’s on-site pipeline layout, system height difference, closed cooling tower resistance loss, internal resistance loss of production heating equipment, and the local resistance loss of each pipe fitting. If a completely closed system is adopted, the height difference and outlet pressure consumption will not need to be considered, and the head of the pump can be reduced. According to the above parameters, plus Oasis Bingfeng’s 20 years of experience in producing water pumps, select the appropriate pump type, parameters, and brand. Usually, a vertical pipeline circulation pump is selected, which is composed of a motor, a pump body, an impeller and a seal, and sometimes a horizontal pipeline pump is used, usually a clean water pump. During the installation process, it is necessary to pay attention to the connection and sealing between the pump and the pipeline, as well as the wiring method and debugging of the motor.
Fifth, install water tanks and water treatment equipment
Water tanks and water treatment equipment are used to store and treat cooling water. When installing a water tank, it is necessary to first determine its capacity and location, and then select the appropriate material and specifications. When installing water treatment equipment, it is necessary to first determine the water quality requirements, and then select the appropriate equipment type and specification.
Sixth, install pipes and valves
Piping and valves are key components to control cooling water flow and temperature. When installing pipes and valves, it is necessary to select appropriate materials and specifications, and install them according to the design specifications. Generally, pipes and valves include water inlet pipes, water outlet pipes, regulating valves, flow meters, pressure gauges, temperature sensors, etc. During the installation process, special attention should be paid to the connection and sealing of pipes and valves, as well as the switching and adjustment of valves.
Seventh, test and debug
Testing and commissioning are critical steps in ensuring the proper functioning of your fluid cooler. Before testing, it is necessary to check whether all parts and equipment have been installed properly, and test according to the equipment operation manual. The testing process usually includes checking parameters such as hydrostatic testing, mechanical properties, electrical properties, water flow, temperature and pressure. During testing, adjustments and repairs are made to design specifications to ensure that the fluid cooler will perform as expected.
