Cooling tower parts
Damagostar company produces all kinds of cooling tower accessories (cooling tower) in different parts of aeration system (fan or impeller and speed reduction), water spill and spraying part (nozzle, water dispenser and internal branches) and other internal components such as packing (cooling surfaces) or It is a dropper (eliminator). The cooling parts of the cooling tower produced by this company are in different categories and include all the spare parts required for the water cooling device. Parts of each particular model of cooling tower must be replaced or repaired during each maintenance period of the cooling cooler .
Important Note: Replacing the accessories of industrial equipment sometimes requires the technical knowledge of experts, and of course this issue in the cooling tower should be done by experienced specialists.
The components of an industrial equipment (such as a cooling tower) depend on the type and operation of a different device. For example, the water flow and distribution part in a cubic cooling tower is completely different from the water circulation part in a conical cooling tower, and as a result, the internal components of this model of cubic and circular towers are also different from each other. The water distribution system in the cubic cooler is of the fixed nozzle type of the cooling tower and low pressure, while the water flow and rotation section in a circular cooling tower is of the rotary type ( sprinkler or hydrothermal cooling tower ) and is made of metal material.
Result: The first step in replacing peripherals is to determine the capacity and type of cooling tower.
The need to replace the cooling tower parts
The cooling tower as a refrigeration source is responsible for cooling the heating devices and is generally designed to work continuously (Continus) and therefore is in constant contact with the water flow and suction air flow. Concentration of soluble materials (TDS - Total Disolved) Solid) water is constantly increasing due to constant evaporation in this industrial cooling model. Increasing the concentration of water-soluble substances causes sediment and clogging in the nozzle, packing and all internal components of the cooling tower. On the other hand there are environmental pollutants and dust in the air in constant contact with sediment and accessories Kvlyngtavr caused a sharp depreciation Mygrdd.tabsh more direct sun slowly deplete components like fan or propeller , drop-consuming and the Louvre.
Therefore: periodic replacement and repair of parts The main solution will be to prevent the destruction of the internal components of the cooling tower and thus maintain the performance of this device.
In the figure below, due to periodic inspection, improper maintenance in the cooling tower, a strong growth of sediment, bacteria and environmental pollutants is observed.
Cooling tower spare parts
As mentioned, periodic inspection of the cooling tower, repair and replacement of internal components is one of the most important principles of maintenance in this cooling source. If the visit to the cooling tower or descaling periods of the internal parts is delayed, the efficiency of the cooling tower will be severely reduced. Supply of spare parts for the cooling tower is in fact one of the most important principles of facility engineering in the maintenance of the cooling tower.
In many industrial plants, in order to prevent severe damage due to lack of proper inspection of the internal components of industrial and refrigeration equipment, a complete set of spare parts of the equipment is always purchased. Cross-flow cooling tower spare parts can be very effective in maintaining this device in an emergency (especially when the cooling tower is operating permanently). Important spare parts of this model of industrial cooler include nozzle or nozzle, packing, dripper and cooling tower impeller.
In simpler terms, spare parts of the reverse flow cooling tower are a complete set of internal and important equipment of different parts of the cooling tower . Parts such as nozzle or water dispenser, packing, impeller or fan and the main equipment of this industrial equipment are The piece is used.
Types of cooling tower accessories
1- Packing or cooling surfaces
Cooling tower packing is in fact the main part of heat transfer and creating the level of communication between the weather in the cooling tower. In other words, the most important part of creating a heat transfer exchange surface is packing the cooling tower. Packing media is affected by permanent sedimentation and clogging due to the constant evaporation of water on its surface. Descaling and relieving clogging of the cooling tower packing must be done continuously and periodically in each period of repairs and service. In fact, the most important part of the cooling tower components is the packing media, because the deposition and clogging of the packing causes a sharp decrease in efficiency and thus increases the water outlet temperature of the cooling tower.
Cooling tower packing is generally produced and designed in two types of splash and packing film. Splash packing has a spray mechanism in the cooling tower and also Film packing has gravity or downstream flow (cascading).
Cooling tower packing descaling:
If the packing or cooling surfaces become clogged, special acidic materials suitable for the packing material are used for acid washing. When replacing the packing, care should be taken to replace the cooling tower according to the type of use and the effective packing surface. In fact, descaling the packing cooling tower is one of the most important parts of the cooling tower component repair period.
Cooling tower packing replacement:
Choosing the right material and type of packing actually requires technical knowledge in the field of cooling tower inlet water quality, inlet water temperature and type of use of this equipment. For example, in cases where the inlet water of the cooling tower has heavy solutes (high TDS), the cooling tower packing of splash type with less fouling is used. Splash cooling tower packing also has a very high temperature resistance against the hot water temperature of the cooling tower inlet.
2. Cooling tower dripper
Drip Eliminator, also known as Drift Elminator in English, actually avoids dropping spray nozzle water on a suction fan or impeller. The dripper is subject to permanent wear and tear due to constant contact with saturated air as well as direct sunlight from the pores between the fan blades.
The dripper is another part of the cooling tower that needs to be replaced on average every 3 to 5 years. Replacement of dripper is important because the destruction and improper operation of the dripper causes water droplets to penetrate the impeller and the reduction part and as a result causes damage and corrosion of metal parts in this part. The cooling tower dripper is one of the internal components of the cooling tower cooling system, which is responsible for protecting the aeration system (impeller).

3. Cooling tower fan
Cooling Tower Fan is the most important part of the aeration and ventilation system in all types of suction and blower cooling, which is in fact subject to failure due to constant rotation around a fixed axis through shear force in the blade and handle. In other words, one of the first components of a cooling tower that has a high sensitivity is the fan or impeller.
The fan bearing is one of the points in the cooling tower that must be constantly changed and inspected during each repair period. Crushing and breaking of the bearing due to the imbalance of the fan will cause the blade to break and damage to other basic parts of the cooling tower. In order to prevent serious damage to the cooling tower impeller, it is recommended that the dynamic balance and static balance of the fan be tested every 12 months.
*** It is recommended that the balance of the cooling tower fan be checked and tested by the relevant experts during each cooling tower repair period.
4. Cooling tower nozzle
The cooling tower nozzle or in fact the nozzle is the main center of water distribution and discharge, which is usually installed as a threaded connection in the fixed water spraying system, and for this reason, in many cases, the water injector nozzle or shower will soon be clogged at the connection. It gets worse. Sediment and clogging in the nozzle will block the outlet of the water entering the cooling tower, and this will cause pressure on the circulator pump over time. Therefore, visiting Afshanak periods in each repair period is another principle of maintenance of this equipment. The cooling tower polymer nozzle, which is made and installed from polypropylene material, is generally easily descaled by acid washing at this stage.
5. Water dispenser cooling tower
The Sprinkler Head is a rotating water distribution and spraying center in a circular fiberglass cooling tower. Sprinklerhead is also known as cooling tower hydrogen, which is generally produced and supplied from aluminum, brass or polymeric materials. A round tower sprinkler actually consists of two fixed and rotating parts. The fixed part of the sprinkler head is usually connected to the inlet pipe and by rotating the inlet water to the cooling tower, the rotating part of the distributor water starts to rotate.
Due to the constant rotation of the rotating part of the water dispenser on the fixed part of the sprinkler, this part constantly suffers from sedimentation, clogging and lack of proper rotation. As a result, the sprinkler cooling tower must be serviced, lubricated, or replaced during each repair and inspection period.
6. Body parts
Fiberglass body parts may need to be replaced or repaired during the life of the cooling tower. Wet fiberglass cooling tower body parts include Louvre, panel or wall, neck and column, which generally depends on the type of parts, fiberglass body parts of cooling tower have a thickness of 5 to 10 mm. Fiberglass parts produced depending on the type of thickness And is a number of different layers of fibers and resin. The fibers are generally in three grades: wicker, needle and powder. The combination of all three types of fibers in the production of fiberglass body parts increases the strength and final quality.
The number of layers of fibers and resin as well as the grade of unsaturated polyester resin (isophthalic or orthophthalic) increases the thickness and guarantees the final quality of the body of all types of dry cooling towers . The Louvre (air intake valve) is one of the internal components of the cooling tower that is constantly in contact with the outside air. This section generally needs to be replaced every 4 to 5 years. In order to replace fiberglass parts, the dimensions of different parts must be molded and produced in the fiberglass parts production workshop.
7. Cooling tower speed reduction system
The complete speed reducer set is responsible for reducing the engine output speed by a certain amount. Speed reduction includes pulley, round bottom bearing, transmission shaft, motor pulley and belt. The transmission system is generally used to adjust the impeller rotation in the cooling tower. There are different types of cooling tower speed reduction and it is designed according to the impeller diameter, speed ratio and type of efficiency (industrial or non-industrial). The most common types of cooling tower speed reduction systems are gearbox and belt type.
