Introduction
1. Core Function
The ACC gearbox is typically mounted above the fan, connecting directly or via a coupling to the fan impeller. Positioned on the top platform of the air-cooled island, it operates under harsh environmental conditions (large diurnal temperature variations, dust, rain, vibration, etc.). Consequently, it demands exceptionally high reliability, efficiency, and durability.
2. Design Features
High Power Density: Transmits significant power within a limited installation space.
High Torque Capacity: Withstands instantaneous high torque caused by fan start-up and wind gusts.
High Reliability: Design life is typically matched with the plant's overhaul cycle, often exceeding 20 years.
Efficient Heat Dissipation: Equipped with an external or internal forced lubrication system to ensure gears and bearings operate at optimal temperatures.
Excellent Sealing Performance: Utilizes multiple sealing designs to prevent lubricant leakage and ingress of external contaminants.
Shock and Vibration Resistance: Robust housing structure and precision bearing arrangements to cope with continuous vibrational loads.
Applications
1. Primary Application Fields
Thermal Power Plants: This is the primary application. Used in the cooling fans of Direct Air-Cooled Condenser (ACC) systems to condense the exhaust steam from turbines. It is a key water-saving component for power plants.
Petrochemical and Metallurgical Industries: Used in air-cooled heat exchangers for various process units (e.g., refineries, fertilizer plants, steel mills) to cool process fluids.
Gas Turbine Power Stations: Used for ventilation in intercoolers or aftercoolers.
Geothermal Power Generation: Used in the cooling systems of condensers.
2. Role in the System
In an air-cooled island, dozens or even hundreds of fans are arranged in a matrix. Each fan is driven by an electric motor and a dedicated gearbox. The performance of the gearbox directly impacts the cooling efficiency, energy consumption, and operational stability of the entire air-cooling system. A failure of a single gearbox can lead to unit load reduction or even shutdown, making its reliability absolutely critical.
