The Correct Installation Method for a Dedicated Centrifugal Fan in a Hospital


When installing a dedicated centrifugal fan in a hospital, proper installation and maintenance are crucial for ensuring efficient operation and extending the equipment’s lifespan. Below are some key steps and considerations:


1. Carefully Read the User Manual

Before using the equipment, be sure to thoroughly read the manufacturer’s user manual to understand the power supply requirements, operational guidelines, and safety precautions. This helps ensure the fan is correctly installed and operated, reducing the risk of faults or safety hazards caused by improper handling.


2. Ensure Stable Power Supply Voltage

Centrifugal fans have specific power supply voltage requirements. Generally, voltage fluctuations should be kept within ±10% of the standard value. If voltage fluctuations exceed this range, using a voltage stabilizer is recommended to maintain a stable power supply.


3. Perform Proper Power Connection

Follow the equipment requirements to ensure power wiring meets the standards. Typically, a three-phase four-wire system is used, which includes three-phase power and a neutral wire. When using three-phase power, the neutral wire should be separate from the ground wire. Whether using three-phase industrial power or single-phase power, ensure the ground wire is reliably connected to prevent electric leakage. Do not connect the ground wire to heating pipes or water pipes.


4. Select an Appropriate Installation Location

The fan should be installed on a flat, solid surface. For large fans, it is especially important to ensure the ground is stable to prevent operational anomalies caused by an unstable foundation. After installation, inspect all fan components to confirm they are securely connected and verify that the transmission parts move smoothly.


5. Regular Maintenance and Servicing

To extend the lifespan of the fan, perform regular maintenance, including:

  • Cleaning: Regularly clean the fan impeller, housing, and motor surface to remove dust and dirt, preventing dust accumulation from affecting equipment performance.
  • Inspection: Periodically check the connections of cables, power supply, and ground wires to ensure they are secure and free of looseness or aging. Additionally, check for foreign objects or dust accumulation inside the fan and impeller, and ensure the safety valve operates correctly.
  • Lubrication: Add lubricant to components such as bearings at regular intervals, as specified in the user manual, to reduce wear and ensure smooth fan operation.

By following these steps, users can ensure the safe and efficient operation of the centrifugal fan in hospitals and effectively prolong its service life.
