Air volume: Calculate the required gas volume based on the process (unit: m³/min). It is recommended to reserve a margin of 10% to 20% to accommodate fluctuations.

Mechanical vibration: The bearing seat/casing shakes violently, accompanied by abnormal noise. The impeller is covered with dust/corrosion, causing the rotor to be unbalanced; the coupling alignment is off; the anchor bolts are loose; the bearing is worn or the clearance is too large Surge phenomenon:

The maintenance cost of multi-stage centrifugal blowers is generally low,especially for models utilizing magnetic suspension bearing technology.Due to achieving zero contact,no lubrication,and no mechanical wear,the annual maintenance cost can be reduced by over 70%compared to traditional Roots blowers,making them a cost-effective choice in industrial energy-saving retrofits.

Vacuum degree: The required working pressure is determined according to the process (such as 100-200 Pa for clothing ironing and 10 ⁻² -10 ⁰ Pa for semiconductor front-end pumping).

A multi-stage centrifugal blower is an industrial equipment that uses a multi-stage impeller series structure to compress and transport gases through high-speed rotating impellers. The following will provide a comprehensive introduction from four aspects: working principle, structural composition, application scenarios, and advantageous features.

Multi stage blowers are extremely sensitive to vibration, and abnormal vibration is usually caused by the following reasons: Loose bearing installation: If the standard tightness is not reached when replacing the bearing, it will cause increased vibration during operation
