在粉体、颗粒物料的输送系统里，旋转供料器就像一位勤劳的 “搬运工”，持续稳定地将物料从一处送往另一处。然而，即便是这位 “老伙计”，在长期工作中也难免遇到各种状况。了解这些常见问题及其解决之道，能让它始终保持高效运转。

　　In the conveying system of powder and granular materials, the rotary feeder is like a diligent "porter", continuously and stably transporting materials from one place to another. However, even this' old buddy 'is bound to encounter various situations in his long-term work. Understanding these common problems and their solutions can keep it running efficiently at all times.

　　一、堵塞：物料 “卡壳” 的困扰

　　1、 Blockage: The problem of material "jamming"

　　堵塞是旋转供料器最常遇到的问题之一。当输送的物料湿度较大，或是具有粘性，在供料器内部堆积，就容易造成堵塞。比如在输送受潮的煤粉、含水量超标的粮食颗粒时，物料会黏附在供料器的转子、壳体壁上，随着时间推移，堆积越来越多，最终导致通道被堵，供料中断。解决堵塞问题，首先要在源头把控物料质量，避免将湿度超标的物料送入供料器；其次，可在供料器进料口处安装振动装置，通过持续的轻微振动，防止物料堆积；若堵塞已经发生，需及时停机，打开供料器检修口，小心清理内部积料，同时检查转子与壳体之间的间隙是否因磨损变大，如有问题及时修复或更换部件，恢复正常的供料通道。

　　Blockage is one of the most common problems encountered by rotary feeders. When the conveyed material has high humidity or viscosity and accumulates inside the feeder, it is easy to cause blockage. For example, when transporting damp coal powder and grain particles with excessive moisture content, the materials will adhere to the rotor and shell wall of the feeder, accumulate more and more over time, and ultimately cause the channel to be blocked and the feeding to be interrupted. To solve the problem of blockage, the first step is to control the quality of materials at the source and avoid sending materials with excessive humidity into the feeder; Secondly, a vibration device can be installed at the feed inlet of the feeder to prevent material accumulation through continuous slight vibration; If blockage has occurred, it is necessary to stop the machine in a timely manner, open the feeder inspection port, carefully clean the internal material accumulation, and check whether the gap between the rotor and the housing has increased due to wear. If there is a problem, repair or replace the components in a timely manner to restore the normal feeding channel.

　　二、磨损：“体力不支” 的隐患

　　2、 Wear and tear: the hidden danger of "insufficient physical strength"

　　长期与物料摩擦，会让旋转供料器的转子、叶片、密封件等部件出现磨损。特别是输送硬度较高的物料，如石英砂、矿石颗粒时，磨损情况会更加严重。磨损一旦加剧，不仅会降低供料精度，还可能导致物料泄漏，影响生产环境和效率。为减少磨损，可在供料器易磨损部位加装耐磨衬板，选用硬度高、耐磨性强的材料，如陶瓷、耐磨合金等；定期检查密封件状态，发现老化、破损及时更换；合理控制供料器的运行速度，避免因转速过快加剧摩擦；还可以在物料中添加适量的润滑剂（在不影响物料性质的前提下），降低物料与部件之间的摩擦力，延长设备使用寿命。

　　Long term friction with materials can cause wear on the rotor, blades, seals, and other components of the rotating feeder. Especially when transporting materials with higher hardness, such as quartz sand and ore particles, the wear and tear will be more severe. Once the wear intensifies, it not only reduces the feeding accuracy, but may also lead to material leakage, affecting the production environment and efficiency. To reduce wear and tear, wear-resistant lining plates can be installed on the easily worn parts of the feeder, using materials with high hardness and strong wear resistance, such as ceramics, wear-resistant alloys, etc; Regularly check the condition of the seals and replace them promptly if aging or damage is found; Reasonably control the operating speed of the feeder to avoid exacerbating friction due to excessive speed; It is also possible to add an appropriate amount of lubricant to the material (without affecting the properties of the material) to reduce the friction between the material and the components and extend the service life of the equipment.

　　三、密封失效：物料 “偷跑” 的尴尬

　　3、 Sealing Failure: Embarrassment of Material "Stealing Away"

　　密封失效会导致物料泄漏，不仅造成浪费，还可能污染工作环境，甚至引发安全隐患。造成密封失效的原因有多种，密封件长期使用老化、变形，转子与壳体之间的间隙过大，或是供料器内部压力不稳定等。解决密封问题，需根据不同原因 “对症下药”。定期检查密封件，按照使用周期及时更换；调整转子与壳体的装配间隙，确保其处于合理范围；在供料器进出口安装压力平衡装置，稳定内部压力，防止因压力波动破坏密封结构；对于一些特殊工况，可选用高性能的密封材料和密封形式，如采用唇形密封、迷宫密封等组合密封方式，增强密封效果。

　　Sealing failure can lead to material leakage, not only causing waste, but also potentially polluting the working environment and even posing safety hazards. There are various reasons for seal failure, such as long-term aging and deformation of seals, excessive clearance between rotors and shells, or unstable internal pressure of feeders. To solve the sealing problem, it is necessary to "prescribe the right medicine" according to different reasons. Regularly inspect the seals and replace them in a timely manner according to their usage cycle; Adjust the assembly clearance between the rotor and the housing to ensure it is within a reasonable range; Install pressure balancing devices at the inlet and outlet of the feeder to stabilize internal pressure and prevent damage to the sealing structure due to pressure fluctuations; For some special working conditions, high-performance sealing materials and sealing forms can be selected, such as using lip seals, labyrinth seals, and other combination sealing methods to enhance the sealing effect.

　　四、异常振动与噪音：“身体不适” 的信号

　　4、 Abnormal vibration and noise: signals of 'physical discomfort'

　　运行过程中，旋转供料器若出现异常振动和噪音，就像是在 “喊疼”，提示设备可能存在故障。这可能是因为转子动平衡被破坏，轴承磨损、松动，或是基础安装不牢固等。遇到这种情况，首先要停机检查转子是否有变形、磨损，如有需要进行动平衡校正；检查轴承的润滑情况和磨损程度，及时补充润滑脂或更换磨损的轴承；重新加固供料器的基础，确保安装稳固，减少因基础不稳引发的振动；此外，还要检查传动部件，如皮带、联轴器等是否安装正确，有无松动或磨损，保证传动系统的平稳运行。

　　During operation, if there is abnormal vibration and noise in the rotating feeder, it is like shouting pain, indicating that the equipment may have a malfunction. This may be due to the rotor dynamic balance being disrupted, bearing wear and looseness, or unstable foundation installation. In this situation, the first step is to stop the machine and check if the rotor is deformed or worn. If necessary, perform dynamic balance correction; Check the lubrication condition and wear level of the bearings, promptly replenish lubricating grease or replace worn bearings; Reinforce the foundation of the feeder to ensure stable installation and reduce vibrations caused by unstable foundations; In addition, it is necessary to check whether the transmission components, such as belts, couplings, etc., are installed correctly, whether they are loose or worn, to ensure the smooth operation of the transmission system.

　　五、动力不足：“力不从心” 的困境

　　5、 Lack of power: the dilemma of 'insufficient strength'

　　当旋转供料器出现动力不足，表现为转速下降、供料量不稳定时，可能是电机故障、传动系统打滑，或是负载过大导致。解决动力问题，需检查电机的运行参数，如电压、电流是否正常，若电机存在故障，及时维修或更换；检查传动皮带的张紧度，调整到合适状态，防止打滑；清理供料器内部堵塞物料，减轻设备负载；如果是长期高负荷运行导致动力衰减，可考虑升级电机功率或优化传动系统，提高设备的动力输出能力，确保供料器稳定运行。

　　When the power of the rotary feeder is insufficient, manifested as a decrease in speed and unstable feeding amount, it may be caused by motor failure, transmission system slippage, or excessive load. To solve power problems, it is necessary to check the operating parameters of the motor, such as whether the voltage and current are normal. If there is a fault in the motor, it should be repaired or replaced in a timely manner; Check the tension of the transmission belt, adjust it to the appropriate state, and prevent slipping; Clean up the blocked materials inside the feeder to reduce equipment load; If the power attenuation is caused by long-term high load operation, upgrading the motor power or optimizing the transmission system can be considered to improve the power output capacity of the equipment and ensure the stable operation of the feeder.

　　旋转供料器在工作中遇到的问题多种多样，但只要熟悉这些常见状况，掌握相应的解决方法，做好日常维护和检查，就能让这位 “物料搬运工” 始终干劲十足，在生产线上发挥重要作用，保障物料输送的顺畅与高效。

　　There are various problems encountered in the operation of the rotary feeder, but as long as one is familiar with these common situations, masters the corresponding solutions, and completes daily maintenance and inspection, this "material handler" can always be full of enthusiasm and play an important role in the production line, ensuring smooth and efficient material transportation.
