稀相气力输送系统选用罗茨鼓风机的核心原因

　　The core reason for selecting Roots blower for dilute phase pneumatic conveying system

　　1. 适配工况需求：稀相输送需低压（0.010.07MPa）、大流量、连续稳定气流，罗茨风机恒流量特性可精准满足物料悬浮输送的风速要求（通常1225m/s），避免物料沉积堵管。

　　1. Adaptation requirements: Low pressure (0.010.07MPa), high flow rate, and continuous stable airflow are required for dilute phase conveying. The constant flow characteristic of Roots blower can accurately meet the wind speed requirements for material suspension conveying (usually 1225m/s), avoiding material deposition and pipe blockage.

　　2. 运行可靠性强：结构简单（无内压缩部件）、故障率低，能适应粉尘环境下的长时间连续运行，契合工业生产中“少停机、高产能”的核心诉求。

　　2. Strong operational reliability: With a simple structure (no internal compression components) and low failure rate, it can adapt to long-term continuous operation in dusty environments, meeting the core demands of "less downtime and high production capacity" in industrial production.

　　3. 成本与效率平衡：相比离心风机，罗茨风机在低压大流量区间效率更高，且购置、运维成本更低；相比空压机，无需复杂的干燥、过滤系统，能耗节省30%50%，降低系统整体投入。

　　3. Cost and efficiency balance: Compared to centrifugal fans, Roots blowers have higher efficiency in the low-pressure and high flow range, and have lower purchase and operation costs; Compared to air compressors, there is no need for complex drying and filtering systems, saving energy consumption by 30% to 50% and reducing overall system investment.

　　4. 调节灵活便捷：通过变频调速可精准调节风量，适配不同物料（如面粉、塑料颗粒）、不同输送距离（通常≤100m）的工况切换，通用性强。

　　4. Flexible and convenient adjustment: Through frequency conversion speed regulation, the air volume can be accurately adjusted to adapt to different materials (such as flour, plastic particles) and different conveying distances (usually ≤ 100m), with strong versatility.

　　5. 抗负载冲击：排气压力受管路阻力影响小，当管路轻微堵塞时，能通过压力自动补偿维持气流稳定，减少系统停机频次，提升运行稳定性。

　　5. Load resistance: The exhaust pressure is less affected by pipeline resistance. When the pipeline is slightly blocked, it can maintain stable airflow through automatic pressure compensation, reduce system shutdown frequency, and improve operational stability.

　　罗茨风机在气力输送系统中的优势：

　　Advantages of Roots blower in pneumatic conveying system:

　　核心卖点：低压大流量+低耗稳运行，解决稀相输送“堵管、停机、高能耗”三大痛点；

　　Core selling point: Low pressure high flow+low consumption stable operation, solving the three major pain points of "pipe blockage, shutdown, and high energy consumption" in dilute phase transportation;

　　客户利益点：设备投资省30%+运维成本降50%+年停机时间＜20小时，助力产能提升15%20%；

　　Customer benefits: equipment investment saved by 30%, operation and maintenance costs reduced by 50%, annual downtime less than 20 hours, helping to increase production capacity by 15% and 20%;

　　应用场景强化：适用于粮食、化工、塑料、建材等行业的粉体/颗粒输送，可直接举例“某面粉厂用罗茨风机实现30m距离10t/h输送，全年无故障运行”。

　　Application scenario enhancement: Suitable for powder/particle conveying in industries such as grain, chemical, plastic, and building materials. For example, a flour mill used a Roots blower to achieve a distance of 30m and a conveying speed of 10t/h, with no faults throughout the year.
