　　旋转供料器的气路系统是保障其与蜜臀国产在线观看协同运行的核心，通过合理的气压控制与气流分配，实现物料密封输送与设备保护，其设计是否合理直接影响供料精度、能耗及运行稳定性。气路系统需兼顾密封、吹扫、辅助动力等多重功能，与机械结构形成联动，确保物料在输送过程中不泄漏、不堵塞。

　　The pneumatic system of the rotary feeder is the core to ensure its coordinated operation with the pneumatic conveying system. Through reasonable air pressure control and airflow distribution, material sealing conveying and equipment protection are achieved. The rationality of its design directly affects the feeding accuracy, energy consumption, and operational stability. The pneumatic system needs to take into account multiple functions such as sealing, blowing, and auxiliary power, and form a linkage with the mechanical structure to ensure that materials do not leak or block during transportation.

　　气路系统的核心构成包括气源装置、控制元件与气路接口叁部分。气源通常来自压缩空气站，经干燥过滤后通过主管道输送至供料器，压力一般控制在稳定范围以满足不同工况需求。控制元件包含电磁阀、压力调节阀、压力表等，电磁阀负责气路的通断控制，可与供料器叶轮转动形成联动（如叶轮每转动一周触发一次补气）；压力调节阀用于精确控制各气路分支的压力，如密封气压力需略高于输送管道压力以防物料反窜。气路接口分布在供料器壳体的关键位置：密封气接口多位于叶轮两端的轴封处，形成气幕阻隔物料进入轴承；吹扫气接口正对叶轮间隙与壳体死角，用于清除残留物料；补气接口则连接至出料口，辅助物料进入输送管道。

　　The core components of the pneumatic system include the gas source device, control components, and pneumatic interface. The gas source usually comes from a compressed air station, which is dried and filtered before being transported to the feeder through the main pipeline. The pressure is generally controlled within a stable range to meet the requirements of different working conditions. The control components include solenoid valves, pressure regulating valves, pressure gauges, etc. The solenoid valves are responsible for controlling the on/off of the air circuit and can be linked with the rotation of the feeder impeller (such as triggering air supply once every rotation of the impeller); Pressure regulating valves are used to precisely control the pressure of each branch of the gas path. For example, the sealing gas pressure needs to be slightly higher than the pressure of the conveying pipeline to prevent material backflow. The air interface is distributed at key positions of the feeder housing: the sealing air interface is mostly located at the shaft seal at both ends of the impeller, forming an air curtain to block the material from entering the bearing; The blowing air interface is facing the clearance between the impeller and the dead corner of the shell, used to remove residual materials; The air supply interface is connected to the discharge port, and auxiliary materials enter the conveying pipeline.

　　气路的密封功能是防止物料泄漏与环境污染的关键。轴封处的气路通过持续通入低压气体，在叶轮轴与壳体之间形成环形气幕，既阻止粉体物料渗入轴承腔造成磨损，又避免外界空气未经处理进入输送系统破坏压力平衡。密封气压力需根据输送物料的特性调整：对于超细粉体，压力需略高于壳体内压力以防粉尘穿透；对于粗颗粒物料，压力可适当降低以减少能耗。当密封气压力异常下降时（如管道堵塞或气源中断），系统会触发报警，提示操作人员检查气路，防止物料泄漏引发设备故障。

　　The sealing function of the gas path is the key to preventing material leakage and environmental pollution. The air path at the shaft seal is continuously filled with low-pressure gas, forming an annular air curtain between the impeller shaft and the housing. This not only prevents powder materials from penetrating into the bearing chamber and causing wear, but also prevents untreated external air from entering the conveying system and disrupting pressure balance. The sealing pressure should be adjusted according to the characteristics of the conveyed material: for ultrafine powders, the pressure should be slightly higher than the pressure inside the shell to prevent dust penetration; For coarse particulate materials, the pressure can be appropriately reduced to reduce energy consumption. When the sealing gas pressure drops abnormally (such as pipeline blockage or gas source interruption), the system will trigger an alarm, prompting the operator to check the gas path to prevent material leakage from causing equipment failure.

　　吹扫气路的作用是清理设备内部残留物料，避免结块堵塞。在叶轮转动间隙，吹扫气通过定向喷嘴对叶片间的物料残留进行吹扫，尤其针对吸湿性强或粘性大的物料，可防止其黏附在壳体内壁形成积料。吹扫气的开启时机与供料器运行状态联动：正常输送时间歇吹扫（如每 10 分钟一次），停机前则进行一次全面吹扫，确保内部无物料残留。吹扫气的压力需适中，过高可能导致物料反冲至料仓，过低则无法有效清除残留，实际应用中需结合物料流动性反复调试。

　　The function of blowing the air path is to clean the residual materials inside the equipment and avoid clumping and blockage. During the rotation clearance of the impeller, the blowing air passes through the directional nozzle to blow away the material residue between the blades, especially for materials with strong moisture absorption or high viscosity, which can prevent them from adhering to the inner wall of the shell and forming material deposits. The timing of opening the blowing gas is linked to the operation status of the feeder: during normal conveying time, intermittent blowing is carried out (such as every 10 minutes), and before stopping, a comprehensive blowing is carried out to ensure that there is no material residue inside. The pressure of the blowing gas should be moderate. If it is too high, it may cause the material to recoil into the silo, while if it is too low, it cannot effectively remove the residue. In practical applications, it needs to be repeatedly adjusted based on the fluidity of the material.

　　补气气路能辅助改善物料输送条件，提升系统稳定性。当输送管道内出现压力波动时，补气气路可向出料口补充适量气体，平衡管道与供料器出口的压力差，避免因压力骤降导致物料堆积。对于比重较大或流动性差的物料，补气能增强气流携带能力，防止在出口处形成搭桥堵塞。补气量需与物料输送量匹配，可通过流量计监测并调节，通常补气量为输送风量的一定比例，既能满足辅助输送需求，又不会过度稀释物料浓度。

　　The air supply circuit can assist in improving material conveying conditions and enhancing system stability. When there is pressure fluctuation in the conveying pipeline, the supplementary gas path can supplement an appropriate amount of gas to the discharge port, balance the pressure difference between the pipeline and the feeder outlet, and avoid material accumulation caused by sudden pressure drops. For materials with high specific gravity or poor fluidity, supplementing air can enhance the carrying capacity of the airflow and prevent the formation of bridging blockages at the outlet. The amount of air supply should match the amount of material conveyed, which can be monitored and adjusted through a flow meter. Usually, the amount of air supply is a certain proportion of the conveying air volume, which can meet the needs of auxiliary conveying without excessively diluting the material concentration.

　　气路系统常见问题多与压力失衡、杂质堵塞相关。压力不稳定会导致密封失效或吹扫不彻底，多因气源压力波动、调节阀失灵或管道泄漏引起，需定期检查气源压力曲线，校准调节阀精度，对管道接口进行气密性测试（如涂抹肥皂水观察是否冒泡）。气路堵塞多因压缩空气中的水分、油污未彻底过滤，在低温环境下凝结成冰或黏附在阀门口径处，可通过加装高效过滤器（如精密滤芯）、定期排水排油解决，同时在寒冷地区对气路管道进行保温，防止冻堵。

　　Common problems in pneumatic systems are often related to pressure imbalance and impurity blockage. Unstable pressure can lead to seal failure or incomplete blowing, often caused by fluctuations in gas source pressure, malfunctioning regulating valves, or pipeline leaks. It is necessary to regularly check the gas source pressure curve, calibrate the accuracy of the regulating valve, and conduct air tightness tests on pipeline interfaces (such as applying soapy water to observe for bubbles). Air path blockage is often caused by incomplete filtration of moisture and oil in compressed air, which condenses into ice or adheres to the valve diameter in low temperature environments. It can be solved by installing high-efficiency filters (such as precision filter cartridges), regularly draining water and oil, and maintaining temperature in the air path pipeline in cold areas to prevent freezing and blockage.
