Convenience Cooling Tower FRP Fan Stack Parts With Long Service Life

Quick Detail:

This profile of fan stack is designed on basis of the theory of air channel uniformity.

The profile of fan stack consists of three sections, suction section, work section and velocity recovery section. The suction section is designed as the ellipse profile in order to decrease the resistance due to the suddenly decrease of air path; the air is draught upper by fan at the work section; some of velocity of exhaust air at velocity section is recovered due to the specially designed profile, so it can greatly increase the power consumption of the fan, save the operation cost.

Specifications:

Description:

1). High Efficiency of Velocity Recovery: Advanceddiffuser profile of fan stack ensures the higher efficiency of velocity recovery than the straight diffuser. The field test indicates that the velocity recovery rate is more than 30%.

 2)Low Resistance: The internal wall of fan stack is coated with two layers of resin so as to keep it slippery, so the resistance is decreased.

3)Rigid and Solid Structure: The fan stack is reinforced by the T-shaped reinforcement where the stress is concentrated, so as to ensure the rigidity and solidity of fan stack. The design wind load is 1200Pa.

4)Convenience for Maintainence: An access door is designed on the fan deck, and a check-way to the fan supports platform is designed inside of the fan stack, and a veiwport is designed for looking at operating status of the fan.

5)Long Service Life: The service life of the fan stack is no less than 20 years at design condition.

6)Ageing Resistance and Ultraviolet: The exterior surface is coated with the resin coating supplied by Ashland Chemical Corp (USA), which can effectively resist the ageing and the ultraviolet.

7)Small Tip Clearance: The clearance between the blade tip and the internal wall of fan stack is controlled smaller than the provision of National standard GB/T 7190.2-2008. Smaller clearance helps to improve the fan efficiency.
