The core basic parameters of multi-stage centrifugal blowers for industrial equipment selection requirements are as follows:

Wind pressure/outlet pressure rise: The conventional range is 15kPa~0.2MPa, and some models can cover the range of 10-100kPa, with a compression ratio of 1.15-3.

Imported volumetric flow rate: mainstream coverage of 15~500m ³/min, can be customized and adjusted according to working conditions.

Continuous operation duration: It can operate continuously and stably for more than 1 year within its design life, and the bearing life of some high-quality models can reach more than 3 years.

Operating noise: The overall operating noise is ≤ 85dB (A), belonging to the low pulsation, oil-free clean gas supply type.

Spindle speed: It is usually several thousand revolutions per minute, much lower than single-stage high-speed fans, and has stronger operational stability.

Suitable working environment: ambient temperature -35~40 ℃, relative humidity 20%~90%, capable of conveying air and non corrosive special gases.

Motor power range: Conventional single machine power covers 22-800kW, suitable for 380V conventional industrial power supply.

Bearing vibration value: The optimized design model has a bearing amplitude of ≤ 0.04mm and operates smoothly without pulse without adding vibration reduction devices.
