Centrifugal blower is a commonly used ventilation equipment in industrial production, which accelerates and exhausts gas through centrifugal force. When selecting a centrifugal blower, it is necessary to determine the specification standards based on specific usage and process requirements. The following will introduce the specifications and standards of centrifugal blowers from the following aspects.

1. Air volume: The air volume of a centrifugal blower refers to the volume of gas passing through the blower per unit time. According to actual needs and process requirements, it is necessary to determine the required air volume. The required air volume can be determined through calculations or experiments to determine the specification standards of centrifugal blowers.

2. Pressure: The pressure of a centrifugal blower refers to the sum of static pressure and dynamic pressure that the blower can produce. Different process requirements have different pressure requirements, so it is necessary to determine the pressure specifications of the centrifugal blower based on specific requirements. Generally speaking, factors such as system resistance and gas delivery distance need to be considered to determine the required pressure.

3. Speed: The speed of a centrifugal blower directly affects its air volume and pressure. Excessive speed may lead to increased noise and energy consumption, while low speed may affect the efficiency of the blower. Based on specific process requirements and equipment characteristics, it is necessary to select an appropriate speed range and determine the specifications and standards of the centrifugal blower on this basis.

4. Power: The power of a centrifugal blower refers to its required electrical energy or energy consumption. Based on process requirements and economic cost considerations, it is necessary to choose an appropriate power range. Power is closely related to air volume, pressure, and efficiency, so these factors need to be comprehensively considered when determining the specifications and standards of centrifugal blowers.

5. Material: The material of the centrifugal blower is directly related to its service life and corrosion resistance performance. According to the working environment and gas characteristics, appropriate materials need to be selected. Common materials include carbon steel, stainless steel, etc. The material specifications for centrifugal blowers are determined based on specific circumstances.

In addition, other factors need to be considered, such as installation method, external dimensions, noise level, reliability, etc. When choosing a centrifugal blower, you can refer to relevant national or industry standards, or customize it according to specific needs.

In summary, the specifications and standards of centrifugal blowers involve multiple aspects such as air volume, pressure, speed, power, and material. When selecting a centrifugal blower, it is necessary to consider the above factors comprehensively based on specific needs and process requirements, and refer to relevant standards to choose a suitable centrifugal blower specification to ensure that it can meet production needs and provide stable and reliable ventilation effects.
