The forward-canted centrifugal fan features a forward-canted cabinet design, which effectively reduces the damage caused by high temperatures and improves machine heat dissipation.

Essentially, the forward-canted centrifugal fan is a variable flow constant pressure device. At a constant speed, theoretically, its pressure and flow curve should be linear. However, due to internal losses, the actual characteristic curve is influenced by changes in inlet conditions, temperature, or density.

Impact of Temperature on Fan Performance: Low-temperature air (low density) reduces inlet pressure, which in turn affects the pressure and flow characteristics. For a given flow rate, if the inlet temperature decreases, the required output increases.

Limitations of Existing Energy-Saving Adjustment Methods: Currently, many stone processing enterprises use outdated energy-saving methods for fan regulation, commonly employing throttling valves. When throttling valves are used, the fan’s flow is mainly adjusted via a regulating valve or throttling damper. At low load conditions, throttling losses can be severe, sometimes exceeding 50%, leading to significant energy waste.

Solution: By adjusting the speed of the forward-canted centrifugal fan, throttling losses can be reduced, ensuring that the fan operates continuously within its efficient range. This method effectively improves the fan’s energy efficiency and is in line with the emerging energy-saving trends in the building materials industry.

Power Supply Protection and Usage Recommendations: To ensure the normal operation of the forward-canted centrifugal fan, any factors that may affect its performance, especially environmental factors, must be eliminated. The fan’s operation depends on a stable power supply, so special attention should be paid to power line protection. To avoid circuit damage, do not use multiple high-power electrical devices simultaneously, as this could interfere with the fan’s normal functioning.
