Flow Regulation for 200 kW High-Pressure Centrifugal Fans

Flow Regulation for 200 kW High-Pressure Centrifugal Fans

The flow rate of 200 kW high-pressure centrifugal fans should be adjusted frequently in accordance with the load on the host machine. Currently, the energy-saving speed control methods for 200 kW high-pressure centrifugal fans used in stone processing enterprises are outdated; throttling speed control is now widely adopted for these fans. When throttle valves are used on 200 kW high-pressure centrifugal fans, the flow rate is primarily regulated by control valves or throttle plates. At high flow rates and low loads, throttling can exceed 50%. Due to throttling losses and the deviation from the high-efficiency operating range, energy wastage is extremely severe. However, by adjusting the rotational speed of the 200 kW high-pressure centrifugal fan, throttling losses can be eliminated, allowing the fan to continue operating within its high-efficiency range and thereby achieving significant energy savings. It can be said that regulating the rotational speed of 200 kW high-pressure centrifugal fans to optimise their operation is an effective energy-saving method, reflecting the current trend in the building materials industry.
