混凝土搅拌机“闷罐”是指搅拌叶轮在生产过程中突然被混凝土卡住，不能转动。在这种情况下，搅拌机主电机通电后将停止运转。如果电气保护部分没有及时保护，或者保护时间等参数设置不合理，主电机就有被烧毁的危险。混凝土搅拌机闷罐的原因：

"Closed tank" of concrete mixer refers to that the mixing impeller is suddenly stuck by concrete during production and cannot rotate. In this case, the main motor of the mixer will stop running after being powered on. If the electrical protection part is not protected in time, or the setting of parameters such as protection time is unreasonable, the main motor is in danger of being burned. Reasons for concrete mixer stuffing:

严重超载，此时需要重新调整进料质量，排出多余的物料；搅拌机衬板磨损严重，或搅拌叶片磨损严重，导致搅拌叶片与搅拌机衬板间隙过大，或间隙严重不均匀，这也是经常出现的原因闷罐。这种情况下，搅拌叶片和搅拌衬板之间必然会有比较硬粗的骨料，卡住搅拌机，也就不足为奇了。

In case of serious overload, it is necessary to readjust the feeding quality and discharge excess materials; The mixer lining plate is seriously worn, or the mixing blade is seriously worn, resulting in excessive clearance between the mixing blade and the mixer lining plate, or the clearance is seriously uneven, which is also the frequent cause of tank stuffing. In this case, there must be hard and coarse aggregate between the mixing blade and the mixing lining plate, so it is not surprising that the mixer is stuck.

搅拌叶片或侧叶片之间有较大的异物和罐的内壁。这时需要手动异物，重新调整间隙；喂料比例不合理，或顺序错误，可能会造成罐子闷，尤其是喂料时。没有水，搅拌阻力会大大增加。电机皮带太松，动力传递不足。这时，需要调整张紧装置以收紧皮带。搅拌臂断、电机相位不平衡、电源电压低等异常情况也可能造成“闷罐”。

There are large foreign matters and the inner wall of the tank between the mixing blades or side blades. At this time, it is necessary to manually remove foreign matters and readjust the clearance; Unreasonable feeding proportion or wrong sequence may lead to stuffy cans, especially when feeding. Without water, the mixing resistance will increase greatly. The motor belt is too loose and the power transmission is insufficient. At this time, the tensioning device needs to be adjusted to tighten the belt. Abnormal conditions such as broken mixing arm, unbalanced motor phase and low power supply voltage may also cause "tank stuffing".

搅拌机“抱大轴”（指搅拌机主轴粘结大量混凝土）)，或其他部分粘合过多的混凝土也是“闷罐”的常见原因。搅拌机里的粘东西越多，搅拌阻力就越大，严重的会造成罐子闷。在这种情况下，操作人员应密切关注搅拌主机的当前值。如果电流值过大，可能需要清洁搅拌机内部。

The "holding shaft" of the mixer (referring to a large amount of concrete bonded to the main shaft of the mixer), or too much concrete bonded to other parts, is also a common reason for "tank stuffing". The more sticky things in the mixer, the greater the mixing resistance, which will cause the jar to be stuffy in serious cases. In this case, the operator should pay close attention to the current value of the mixing host. If the current value is too large, it may be necessary to clean the inside of the mixer.

平常要对机器进行维护才能更顺利更长久的使用，做法有很多项目，比如：保证机器及周围环境的清洁。及时料斗内的积料，使传感器正常回零。检查各润滑点的润滑油是否足够，气路系统中的油雾器应保持有足够的油量。检查各电机、电器有无过热现象、异常噪音，仪表指示是否正常，信号系统是否完好。

Usually, the machine needs to be maintained in order to be used more smoothly and for a long time. There are many methods, such as ensuring the cleanness of the machine and its surrounding environment. Timely remove the accumulated material in the hopper to make the sensor return to zero normally. Check whether the lubricating oil at each lubricating point is sufficient, and the oil mist in the air circuit system shall maintain sufficient oil. Check whether each motor and electrical appliance has overheating and abnormal noise, whether the instrument indication is normal and whether the signal system is intact.

经常检查、调整气缸、蝶阀和电磁气阀等，使开启和关闭符合要求。经常检查各系统，如有漏灰、漏气、漏油和漏电等现象要及时处理。每班应放掉空压机、贮气罐和过滤器等内部积水，并排除运行中出现的故障。蝶阀、搅拌机、电磁气阀、空气过滤器及油雾器等按照有关说明书进行维护保养。等等。

Frequently check and adjust the cylinder, butterfly valve and solenoid valve to make the opening and closing meet the requirements. Check each system frequently, and deal with it in time in case of ash leakage, air leakage, oil leakage and electric leakage. Each shift shall drain the accumulated water inside the air compressor, air storage tank and filter, and eliminate the faults during operation. Butterfly valve, mixer, electromagnetic air valve, air filter and oil mist shall be maintained according to relevant instructions. wait.

偶尔会出现混凝土搅拌机的“闷罐”，这也是搅拌机的操作。人员需要密切关注。遇到混凝土搅拌机闷的现象，先检查问题再。更多相关内容您可以来关注我们的网站www.zkhntjbc.com咨询！

The concrete mixing plant occasionally has a "stuffy tank" of the concrete mixer, which is also the operation of the mixer. Personnel need to pay close attention. If the concrete mixer is stuffy, check the problem first and then solve it. For more information, you can follow our website at www.zkhntjbc.com Com consulting!
