AXIAL FANS

Diagnostics and Maintenance of Axial Fans and Driving Units of Cooling Towers

• Vibration measurement
• Bearing diagnostics
• Check the screws and tighten to the correct torque
• Check the level of rotation of the fan
• Check and setting the angles of fan blades
• Check the clearance between the blades and the fan casing
• Check the drainage holes in blades
• Check the oil and air filters on gearboxes
• Check and replacement the transmission oil
• Check the lubricant and lubrication of bearings
• Check surface protection
• Check for wear or damage
• Replacement of spare parts
• Cleaning

Special Service

• Measurement of the aerodynamic performance of the fans (air flow and static pressure)
• Measurement of input power of el. motors
• Setting the angle of the blades of fans to the optimum operating point - optimization of the aerodynamic performance
