company news about 4 key points can accurately customize your centrifugal fan

To provide detailed parameters for custom centrifugal fans, the core is to organize them hierarchically according to "operating condition requirements → performance indicators → adaptation requirements", ensuring each parameter directly supports the supplier's design and avoids ambiguous descriptions. Specifically, you can sort them out in the following 4 steps:

1. First, clarify the "conveyed medium" parameters (determine material and protection design)

- Medium type: Precisely specify whether it is "normal-temperature clean air", "dust-laden gas containing 15% wood chips", "hot air at 350℃" or "chemical waste gas containing 5% acid";

- Additional characteristics: If impurities are present, supplement the impurity particle size (e.g., "dust particle size ≤ 8μm") and whether it is flammable and explosive (e.g., "belongs to IIB class explosive gas environment"); if there are humidity requirements, mark "medium relative humidity ≤ 85%".

2. Then, determine the "core performance" parameters (determine the fan's core design)

- Air volume: Mark "normal value + peak value + test conditions", e.g., "12,000 m³/h for normal operation, 15,000 m³/h for peak operation (under standard atmospheric pressure and medium temperature of 25℃)";

- Air pressure: Specify "total pressure / static pressure" and corresponding working conditions, e.g., "total pressure of 3,200 Pa (when medium temperature is 80℃ and inlet pressure is 0.1 MPa)";

- Efficiency: Specify "fan efficiency ≥ 83% (tested at the design operating point in accordance with GB/T 13274 standard)".

3. Next, supplement the "motor and structure" parameters (determine operational safety and installation adaptation)

- Motor: Explain the type (standard / explosion-proof / variable-frequency), specifications (e.g., "explosion-proof motor Ex d IIB T4, voltage 380V, frequency 50Hz, power 15kW"), and protection level (e.g., "IP54");

- Structure: Mark the air outlet angle (e.g., "135°"), interface specifications (e.g., "air inlet DN500 flange, in line with GB/T 9119-2020"), and cabinet size restrictions (e.g., "maximum length × width × height ≤ 1800mm × 1200mm × 1000mm").

4. Finally, clarify the "special requirement" parameters (determine the design of additional functions)

- Noise: Specify "A-weighted sound level noise ≤ 72dB(A) at 1 meter";

- Additional components: State whether "silencer (noise reduction ≥ 25dB)", "vibration monitor (alarm threshold ≤ 5mm/s)" or "sound insulation cover" is required.
