Construction and production of cooling towers
The process of building or building a cooling tower includes various parts of different parts of the construction of parts and assembling them in the cooling tower. In other words, the process of production and construction of the cooling tower is divided into three main parts. The first part involves the production of cooling tower components and the second part is related to the assembly operation, and the final part is the technical and engineering supervision (quality control).
The process of building a cooling tower must be done with great care, as this results in valuing and valuing the final quality of the equipment produced. The cooling tower has various equipments related to water supply and water supply parts and has different parts that are produced from metal, polymer or fiberglass FRP material. Most manufacturers today are trying to limit the use of metal materials in the production of interior parts of cooling towers and use high-strength materials such as fiberglass or polypropylene instead.
Due to the above, the manufacturers of cooling towers in the production and construction of cooling towers may deal with different parts of production. In fact, building a cooling tower requires technical knowledge in the field of fluid, chemical, electrical, civil and materials engineering. Electric motor is one of the parts related to electrical engineering. Therefore, a successful manufacturer in the construction of cooling towers must have a complete and experienced team of engineers in various fields.
The general steps of building a cooling tower by domestic builders
1- Manufacture of parts and accessories used in different parts such as impeller, nozzle, packing, drip trap and body components
2- Assembly and assembly of parts and equipment on the main body and frame
3- Quality control and technical supervision of the produced product in accordance with various standards and tests, including dewatering test, welding test and pressure test.
Various parts for making cooling tower parts (before assembly)
- Injection of plastic and polymer parts such as nozzle or spray nozzle, drip trap and packing media
- Shaving of metal parts from steel and aluminum materials such as round reduction (Foley) and Sprinkler (water turbine)
- Production of body parts from FRP fiberglass material with fibers and resin and using molding and manual or machine baking method
- Coil chassis welding, drip and pack holder support, fan guard or butterfly guard and butterfly and motor holder chassis at the top of the fan neck
- Construction and production of butterfly blades or cooling tower fans using extruder or hydraulic press and assembling that part is machined with the hub part and then going through the steps of static and dynamic balance of the impeller.
Cooling tower assembly
The process of assembling or finalizing a product involves placing different parts in the intended parts. In fact, the next step in supplying and producing the side components of a cooling tower is the assembly or heading of the cooling tower. This step can be done in two ways according to the necessary qualifications for transportation and installation.
- Assembly at the project site (cooling tower installation site)
- Assembly in the factory or workshop for the manufacture and production of cooling towers
Depending on the capacity and dimensions of the cooling tower, the process of assembling or building a cooling tower can be done in both cases. Generally, capacities of more than 500 tons of refrigeration in the cooling tower are assembled at the project site. Sometimes for various reasons, many manufacturers try to assemble all their products in the form of assembly and delivery to the factory door. Due to this purpose, capacities above 500 tons of refrigeration, which will be very difficult to transport and load, will be designed and produced in multi-cell.
Reasons why construction companies refuse to assemble and build cooling towers at the project site
- Lack of quality control of the technical supervision team correctly and efficiently due to the possible length of the distance
- Decreased product quality due to fatigue due to distance and assembly time on executive and assembly personnel
- Increase production time, construction, installation of cooling towers
- Increase in transportation costs, food, accommodation and staff assembly operations
