Structural Features

 The blower comprises several key parts: impeller, casing, air inlet, air damper, and a supporting frame.

1. 1. Impeller – Made with multiple steel blades, a curved front plate, and a straight rear plate, the impeller is securely riveted and welded for stability. It is dynamically balanced, ensuring high efficiency, low noise, and smooth operation.
2. 2. Casing – Constructed from durable steel plates for long-lasting operation.
3. 3. Air Inlet – The air inlet is a single integral unit positioned on the side of the fan. Its streamlined design helps direct airflow smoothly into the fan, reducing resistance and improving overall efficiency.
4. 4. Air Damper – These blowers come equipped with air dampers, allowing users to adjust both the air volume and pressure to meet the specific requirements of the boiler system.

Performance and Selection Criteria

The performance of the G6-30 and G5-47 fans is measured by airflow rate, total pressure, shaft speed, power consumption, and efficiency. The provided performance data reflects standard operating conditions, with atmospheric pressure at 101325Pa, ambient temperature at 20°C, relative humidity at 50%, and gas density of 1.2kg/m³. If operating conditions differ, performance can be adjusted using applicable formulas. Motor power should always match or exceed the blower’s power requirements for optimal performance.
 

When selecting a centrifugal blower, consider the differences between actual pipe network losses and calculated values, along with any variations in total pressure to ensure proper selection and efficiency.
