The issue of the motor size of the device
Thread Content
I have a gentle question: the motors used in pump units come in different sizes, with larger motors having higher power ratings. Is it true that the greater the flow rate of the fluid pumped, and the higher its viscosity, the more power the motor needs? Thank you, those who know please let me know
Yes, the greater the flow rate of the medium in a pump, and the higher its viscosity, the more motor power is typically required to overcome the resistance of the fluid and provide sufficient power. Therefore, these factors need to be considered when selecting a motor. .
Yes, you can consult the pump manufacturer for specific details
Based on the factory’s power source, steam and electricity balance, process operation requirements, environmental conditions, and practical experience. Selection is made based on medium properties, flow rate, and head requirements.
The size of the motor should be determined by the shaft power； Shaft power (kW) = Flow rate (m³/h) × Head (m) × 9.81 × Specific gravity of the medium ÷ 3600 ÷ Pump efficiency
