A closed cooling tower needs to go through multiple processes from design to put into use to ensure that it can play its due role and maximize its benefits. The first is design and preparation, and the second is assembly fluency, including assembling the tower body, installing the sprinkler system, installing the circulation pump, installing water tanks and water treatment equipment, pipe connections and valves and other accessories, as well as water pressure testing and no-load debugging, etc. step.
During the assembly process, you need to strictly follow 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 to ensure the fluid cooling tower is operating properly. With correct assembly and debugging, closed cooling towers can provide effective heat exchange and cooling effects to meet the requirements of industrial production.
Assembly process of closed cooling tower
1, design and preparation.
During the design and preparation phases, the fluid cooling tower specifications, performance and functional requirements need to be considered. Usually, this requires the use of professional software for detailed design and calculation, and the selection of suitable materials and components, taking into account on-site usage conditions, to achieve full efficiency, meet sufficient power, and extend service life. To ensure that assembly goes smoothly, all necessary tools and equipment need to be prepared.
2, assemble the tower body
The tower body is the core part of the closed cooling tower, including the heat exchange coil and internal frame, equipment shell, filler and nozzle system, wind system, etc. Usually, the steel frame is divided into several modules, 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 extends the 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.
3, install the sprinkler system
The spray system is used to spray spray water evenly on the heat exchange coil. Usually, the sprinkler system consists of a sprinkler pump, pipes, and nozzles. The choice of spray pump is the leading factor in the design. Its selection must first meet the flow requirements and be a key consideration in software calculations 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. block. Secondly, on the premise of overcoming resistance and satisfying the nozzle water pressure, the lift should be reduced as much as possible to save operating power consumption. Finally, in terms of details such as nozzle structure, nozzle connection, and smoothness of the inner wall of the pipe, user considerations such as maintenance, lifespan, and energy saving are taken into consideration.
4, install the circulation pump
The circulation pump is the source of power that drives the flow of internal circulating water and ensures the forward power source during the cooling process of internal circulating water. The basic parameters are flow rate and head, and operating energy consumption is reflected in power, which is the main indicator of energy level. When designing Oasis Bingfeng, detailed calculations were made based on the user’s on-site pipeline layout, system height difference, closed cooling tower resistance loss, and the internal resistance loss of the production heating equipment, and then considering the local resistance loss of each pipe fitting. If a completely closed system is adopted, the height difference and outlet pressure consumption do not need to be considered, and the pump head can be reduced. Based on the above parameters, coupled with Oasis Bingfeng’s 20 years of water pump production experience, select the appropriate pump type, parameters, and brand. Usually, a vertical pipeline circulation pump is selected, which consists of a motor, a pump body, an impeller and a seal. Sometimes a horizontal pipeline pump is also used, usually a clean water pump. During the installation process, attention needs to be paid to the connection and sealing between the pump and the pipeline, as well as the wiring method and debugging of the motor.
5, 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, you need to first determine its capacity and location, and then choose the appropriate materials and specifications. When installing water treatment equipment, you need to first determine the water quality requirements and then select the appropriate equipment type and specifications.
6, install pipes and valves
Pipes and valves are key components in controlling cooling water flow and temperature. When installing pipes and valves, appropriate materials and specifications need to be selected and installed according to design specifications. Usually, 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 needs to be paid to the connection and sealing of pipes and valves, as well as the switching and adjustment of valves.
7, conduct testing and debugging
Testing and commissioning are critical steps to ensure the fluid cooling tower is operating properly. Before testing, check that all components and equipment have been installed properly and perform the test according to the equipment operating 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 need to be made to design specifications to ensure that the fluid cooling tower can achieve expected performance specifications.
