Operating Principles and Installation/Selection Considerations for High-Pressure Centrifugal Fans

Operating Principles and Installation/Selection Considerations for High-Pressure Centrifugal Fans High-pressure centrifugal fans are not only used for ventilation but also for conveying materials. In practical applications, the requirements for media used with high-pressure centrifugal fans are as follows: Medium Temperature: Typically below 50°C, not exceeding 80°C. Particles in the Medium: Dust and hard particles in the medium must not exceed N150mg/m³. 1. Operating Principle of High-Pressure Centrifugal Fans: Upon startup, the fan's impeller gradually accelerates to high-speed rotation. Through centrifugal force, the impeller propels gas forward and outward, creating a series of high-speed rotational movements. Air spirals between the impeller blades, accelerating the gas outside the pump body and forcing it into the side channel. Once in the side channel, the gas is compressed, returns to the impeller blades for further acceleration, and then rotates again. 2. Precautions for Installing High-Pressure Centrifugal Fans: When installing the high-pressure centrifugal fan unit, a stable foundation is essential to maintain structural balance. Additionally, flat washers and spring washers must be used to secure the bolts. Furthermore, rubber buffers should be employed to support the weight of the high-pressure centrifugal fan, particularly for high-power models. In environments with significant noise levels, mufflers can be installed to reduce noise emissions. Furthermore, flexible hoses must connect the inlet and outlet ducts to the high-pressure fan to isolate vibrations. 3. Considerations for purchasing high-pressure centrifugal fans: During procurement, first define specific operational requirements and environmental conditions while assessing the manufacturer's scale and technical capabilities. Simultaneously, verify the reliability and quality assurance of the high-pressure centrifugal fan unit. Investigate whether comprehensive after-sales service is provided and confirm the product holds relevant quality certifications.
