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

The multi-stage centrifugal fan with welded structure is a high-pressure fan composed of multiple impellers connected in series, and its core components are manufactured using welding technology. Compared with single-stage centrifugal fans, multi-stage design significantly improves the wind pressure output capacity by compressing gas step by step.

​Regular maintenance costs The cost of daily inspections (such as cleaning filters and monitoring vibrations) is relatively low, with a single labor cost of about 200-500 yuan.
