Cooling tower fan - Fiberglass cooling tower impeller

Cooling tower fan - Fiberglass cooling tower impeller

The cooling tower fan is responsible for generating and circulating the necessary air to exchange heat inside the tower. The cooling tower impeller is produced in two ways: axial and centrifugal fan. These fans are used in different diameters and with different powers. Azin Ventilation Industrial Group Produce various types of fiberglass cooling tower impellers from one meter to 4.5 meters in diameter. From 50 cm to 100 cm are also made of polyamide impellers with 5 to 9 blades. The price of the axial fan of the cooling tower varies according to the dimensions and materials used in the construction and is from 900 thousand Toman starts and reaches 40 million Tomans.

1- Axial fan with aluminum blade AL 2- Impeller or fan with fiberglass blade FRP 3- Axial fan with above polyamide blade Style 1- Aluminum cooling tower fan One of the first and most common types of ventilation and ventilation system in the cooling tower is the use of a fan with aluminum blades. The blade of this model is made of aluminum alloy. Due to its softness, aluminum can be easily converted into suitable aerodynamic shapes. The best part of the airfoil in air conditioning systems is the airfoil type. The cross-section of the airfoil of the cooling tower fan blade reduces the pressure due to drag (turbulence). Aluminum slats are produced by branching by extrusion machine. Airfoil mold of aluminum blades is 27 cm wide, which is usually offered in the type of 4 to 6 blades. The standard adjustment angle of aluminum turbine blades in the cooling tower is between 14 and 16 degrees. Reducing the angle at the blades reduces the airflow capacity and increasing the pitch angle increases the vibration. Is. Fiberglass blade is widely used in induction cooling towers due to its high resistance to moisture. Induction vacuum systems are at risk of corrosion and damage due to constant contact with saturated moisture coming out of the top of the fan. The use of composite fibers or compressed plastic in the fan blade increases the strength and life of this part. On the other hand, the fiberglass blades used in this model are highly recommended for industrial environments due to their resistance to acids. On the outer wall of the fiberglass blades, a layer of gel is applied to the axial wheels made of composite or plastic. Jelly is a thick resin that forms a thick, hard coating on the outer wall of the cooling tower impeller. 3- Polyamide cooling tower fan Multi-wing fan with polyamide material is one of the most common types of systems. Axial or axial ventilation is due to the use of ultra-lightweight materials. The multi-wing aeration system with its small and light blades creates a small volume of aeration capacity. Due to the low air capacity produced by this model, it is used in small cooling towers (low refrigeration capacity). Multi-Wing cooling tower fan is actually a kind of axial wheel that can adjust the angle. The cooling tower multi-wing turbine has a number of narrow blades (13 to 18 cm). The blades of this fan model are made of ultra-light polyamide (PE) polymer material. Such fans are considered in the super low noise type, the decibel of their output sound is less than 65.
