在粉體、顆粒物料的輸送系統(tǒng)里，旋轉(zhuǎn)供料器就像一位勤勞的 “搬運(yùn)工”，持續(xù)穩(wěn)定地將物料從一處送往另一處。然而，即便是這位 “老伙計(jì)”，在長(zhǎng)期工作中也難免遇到各種狀況。了解這些常見(jiàn)問(wèn)題及其解決之道，能讓它始終保持高效運(yùn)轉(zhuǎn)。

　　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 “卡殼” 的困擾

　　1、 Blockage: The problem of material "jamming"

　　堵塞是旋轉(zhuǎn)供料器最常遇到的問(wèn)題之一。當(dāng)輸送的物料濕度較大，或是具有粘性，在供料器內(nèi)部堆積，就容易造成堵塞。比如在輸送受潮的煤粉、含水量超標(biāo)的糧食顆粒時(shí)，物料會(huì)黏附在供料器的轉(zhuǎn)子、殼體壁上，隨著時(shí)間推移，堆積越來(lái)越多，最終導(dǎo)致通道被堵，供料中斷。解決堵塞問(wèn)題，首先要在源頭把控物料質(zhì)量，避免將濕度超標(biāo)的物料送入供料器；其次，可在供料器進(jìn)料口處安裝振動(dòng)裝置，通過(guò)持續(xù)的輕微振動(dòng)，防止物料堆積；若堵塞已經(jīng)發(fā)生，需及時(shí)停機(jī)，打開(kāi)供料器檢修口，小心清理內(nèi)部積料，同時(shí)檢查轉(zhuǎn)子與殼體之間的間隙是否因磨損變大，如有問(wèn)題及時(shí)修復(fù)或更換部件，恢復(fù)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、磨損：“體力不支” 的隱患

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

　　長(zhǎng)期與物料摩擦，會(huì)讓旋轉(zhuǎn)供料器的轉(zhuǎn)子、葉片、密封件等部件出現(xiàn)磨損。特別是輸送硬度較高的物料，如石英砂、礦石顆粒時(shí)，磨損情況會(huì)更加嚴(yán)重。磨損一旦加劇，不僅會(huì)降低供料精度，還可能導(dǎo)致物料泄漏，影響生產(chǎn)環(huán)境和效率。為減少磨損，可在供料器易磨損部位加裝耐磨襯板，選用硬度高、耐磨性強(qiáng)的材料，如陶瓷、耐磨合金等；定期檢查密封件狀態(tài)，發(fā)現(xiàn)老化、破損及時(shí)更換；合理控制供料器的運(yùn)行速度，避免因轉(zhuǎn)速過(guò)快加劇摩擦；還可以在物料中添加適量的潤(rùn)滑劑（在不影響物料性質(zhì)的前提下），降低物料與部件之間的摩擦力，延長(zhǎng)設(shè)備使用壽命。

　　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” 的尷尬

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

　　密封失效會(huì)導(dǎo)致物料泄漏，不僅造成浪費(fèi)，還可能污染工作環(huán)境，甚至引發(fā)安全隱患。造成密封失效的原因有多種，密封件長(zhǎng)期使用老化、變形，轉(zhuǎn)子與殼體之間的間隙過(guò)大，或是供料器內(nèi)部壓力不穩(wěn)定等。解決密封問(wèn)題，需根據(jù)不同原因 “對(duì)癥下藥”。定期檢查密封件，按照使用周期及時(shí)更換；調(diào)整轉(zhuǎn)子與殼體的裝配間隙，確保其處于合理范圍；在供料器進(jìn)出口安裝壓力平衡裝置，穩(wěn)定內(nèi)部壓力，防止因壓力波動(dòng)破壞密封結(jié)構(gòu)；對(duì)于一些特殊工況，可選用高性能的密封材料和密封形式，如采用唇形密封、迷宮密封等組合密封方式，增強(qiáng)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、異常振動(dòng)與噪音：“身體不適” 的信號(hào)

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

　　運(yùn)行過(guò)程中，旋轉(zhuǎn)供料器若出現(xiàn)異常振動(dòng)和噪音，就像是在 “喊疼”，提示設(shè)備可能存在故障。這可能是因?yàn)檗D(zhuǎn)子動(dòng)平衡被破壞，軸承磨損、松動(dòng)，或是基礎(chǔ)安裝不牢固等。遇到這種情況，首先要停機(jī)檢查轉(zhuǎn)子是否有變形、磨損，如有需要進(jìn)行動(dòng)平衡校正；檢查軸承的潤(rùn)滑情況和磨損程度，及時(shí)補(bǔ)充潤(rùn)滑脂或更換磨損的軸承；重新加固供料器的基礎(chǔ)，確保安裝穩(wěn)固，減少因基礎(chǔ)不穩(wěn)引發(fā)的振動(dòng)；此外，還要檢查傳動(dòng)部件，如皮帶、聯(lián)軸器等是否安裝正確，有無(wú)松動(dòng)或磨損，保證傳動(dòng)系統(tǒng)的平穩(wěn)運(yùn)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、動(dòng)力不足：“力不從心” 的困境

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

　　當(dāng)旋轉(zhuǎn)供料器出現(xiàn)動(dòng)力不足，表現(xiàn)為轉(zhuǎn)速下降、供料量不穩(wěn)定時(shí)，可能是電機(jī)故障、傳動(dòng)系統(tǒng)打滑，或是負(fù)載過(guò)大導(dǎo)致。解決動(dòng)力問(wèn)題，需檢查電機(jī)的運(yùn)行參數(shù)，如電壓、電流是否正常，若電機(jī)存在故障，及時(shí)維修或更換；檢查傳動(dòng)皮帶的張緊度，調(diào)整到合適狀態(tài)，防止打滑；清理供料器內(nèi)部堵塞物料，減輕設(shè)備負(fù)載；如果是長(zhǎng)期高負(fù)荷運(yùn)行導(dǎo)致動(dòng)力衰減，可考慮升級(jí)電機(jī)功率或優(yōu)化傳動(dòng)系統(tǒng)，提高設(shè)備的動(dòng)力輸出能力，確保供料器穩(wěn)定運(yùn)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.

　　旋轉(zhuǎn)供料器在工作中遇到的問(wèn)題多種多樣，但只要熟悉這些常見(jiàn)狀況，掌握相應(yīng)的解決方法，做好日常維護(hù)和檢查，就能讓這位 “物料搬運(yùn)工” 始終干勁十足，在生產(chǎn)線上發(fā)揮重要作用，保障物料輸送的順暢與高效。

　　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.
