Installation And Commissioning Of Industrial Draught Fans

August 14, 2024 | by Reitz India

Industrial draught fans act like the lungs of manufacturing facilities. The draught fans play a vital role in various industrial processes including ventilation, conveying material, supplying combustion air, or exhaust of gases. It requires diligent planning, precise execution, and adherence to safety regulations when it comes to the installation and commissioning of these fans. Let’s take a tour through this insightful guide that covers all essential aspects of fan installation and commissioning from its initial preparation to final testing, diagnostics, and troubleshooting.

A. Preparation before installation
Some steps comprise the detailed preparation followed before the installation process of industrial draught fans. Ensure all necessary resources, safety measures, and machinery equipment are in place before starting the installation.

  1. Safety protocols: Ensure proper training of all personnel involved in the installation and equipped with disaster-resilient personal protective equipment. Also, establish adequate safety protocols for the security of the personnel.
  2. Assessment of site: To determine the optimal location for installation of the draught fan, make a thorough consideration of factors like safety regulations, accessibility for maintenance, and airflow requirements and conduct an assessment of the installation site.
  3. Review of technical specifications: To ensure compatibility with power needs and environmental conditions, review the technical requirements of the fan manufacturer.

B. Installation process
The installation procedure has many sequential steps to ensure integration with the existing infra, correct positioning of the fan, and secure mounting.

  1. Base preparation: Prepare a stable foundation enabling the fan to withstand operational vibrations as well as support the weight. Also check the pedestal and base alignment with master level and the precision engineering instrument as per the protocol.
  2. Assembly: Duly follow the guidelines set by the manufacturer and assemble the components of the fan including bearings and mounting brackets.
  3. Power wiring: Provide electrical supply to the fan according to the wiring diagrams. Ensure proper grounding by following safety standards and regulations for protection against electrical hazards.
  4. Alignment: Precisely use levelling equipment for optimal coupling alignment of the fan shaft with the motor shaft and other components to minimize vibration and ensure smoother operation.

C. Commissioning procedure
The process of commissioning involves fine-tuning the fan apart from operational testing to enhance performance and efficiency.

  1. Functional testing: Execute initial start-up and perform other functional tests. This is made to ensure the correct operation of the fan, motor, and allied control systems. Both cold commissioning and hot commissioning needs to be done.
  2. Performance verification: Calculate the rates of airflow, pressure, power consumption data, and effeciency to ensure they align with the specified design and performance aspects.
  3. Optimisation: Ensure necessary adjustments to control settings, and not just fan and blade designs to get desirable operation and optimize performance.

D. Operational checks and safety measures
After the commissioning of the fan, detailed operational verification is necessary along with the implementation of continuing maintenance procedures.

  1. Safety verification: To prevent mishaps and safety of workers, it is imperative to check the correct functioning of all safety systems like interlocks and emergency shutdowns.
  2. Monitoring and maintenance: Perform a regular maintenance schedule for inspection, cleaning, and processes like lubrication of components to prolong the lifespan of the fan and enhance its operational efficiency.
  3. Diagnostics: To prevent unprecedented downtime and detect shutdown or potential failure issues early, implement remote monitoring systems.

E. Troubleshooting
Implement standard guidelines and systematic troubleshooting protocols in the event of performance issues or operational deviations.

  1. Diagnostics: Use tools like pitot tube, flow meter, manometer, pyrometer, and thermographic cameras to identify core causes of problems in the system.
  2. Tech support: Implement corrective measures as soon as possible with proper consultations with technical support from the manufacturing side or specialists to address complex issues.

Conclusion
On a concluding note by following this step-by-step guide, manufacturers, engineers, or fan operators can meticulously plan, and execute skillfully while adhering to safety standards in installing draught fans. With efficient commissioning and effective maintenance, these practices can greatly help optimize industrial processes and operational performance while improving air quality and ensuring regulatory compliance.
