对于搅拌站来说，要维持正常的生产活动，平时对搅拌机设备的保养、维护非常重要。而实际情况是，搅拌机是出现故障几率比较大的机械。今天小编就和大家讲讲自上料搅拌车的常见故障，以及日常维护要点。

For the mixing plant, to maintain normal production activities, it is very important to maintain the mixer equipment at ordinary times. The actual situation is that the mixer is a machine with a high probability of failure. Today, my editor will tell you about the common failures of the self feeding mixer and the key points of daily maintenance.

1.内部异物

1. Internal foreign matters

自上料搅拌车在搅拌过程中，水泥、较硬的颗粒状骨料（如：石子）等颗粒物会对拌筒内壁造成较大的磨损，尤其在搅拌机使用完毕后，如果没有及时清理，会导致拌筒内的异物变干、变硬，从而对拌筒和搅拌叶片造成更大的磨损，严重影响搅拌机的正常使用。

During the mixing process of the self loading mixer, particles such as cement and hard granular aggregate (such as gravel) will cause greater wear on the inner wall of the mixing drum. Especially after the mixer is used, if it is not cleaned in time, foreign matters in the mixing drum will become dry and hard, which will cause greater wear on the mixing drum and mixing blades, and seriously affect the normal use of the mixer.

2.轴端密封故障

2. Shaft end seal failure

轴端是将电动机与自上料搅拌车滚筒连接起来的重要传动装置，是整个搅拌机的核心部件。在工作过程中，自上料搅拌车通常实施密封处理，但是在实际工作中，轴端往往被灰尘所覆盖，当砂浆进入到轴端后，会造成轴瓦或轴承的磨损和损坏。

The shaft end is an important transmission device connecting the motor and the drum of the self feeding mixer, and is the core component of the entire mixer. In the process of work, the self feeding mixer is usually sealed, but in actual work, the shaft end is often covered with dust. When the mortar enters the shaft end, it will cause wear and damage to the bearing pad or bearing.

3.除尘问题

3. Dust removal

运作过程中，自上料搅拌车需要对原材料进行计量、投料，当粉料或骨料投入到计量容器或搅拌罐筒中时，需要排出里面的空气。排气过程中会造成微小粉尘外扬，这些粉尘不仅使混凝土行业的工作环境恶劣，还会造成机械损坏，影响机械的寿命。

In the process of operation, the raw materials need to be measured and fed by the self feeding mixer truck. When the powder or aggregate is put into the measuring container or mixing tank, the air inside needs to be discharged. The exhaust process will cause small dust to rise outside, which will not only make the working environment of the concrete industry bad, but also cause mechanical damage and affect the service life of the machinery.

除此之外，还会发生其他如人工操作不当、不及时清理搅拌机拌筒、料斗滑道位置不正等问题，所以说建议大家对在平日中多做检查然后定期维护保养。关注我们https://www.zishangliaojiaobanji.cn，带您了解更多相关事项内容！

In addition, there will be other problems such as improper manual operation, untimely cleaning of the mixer mixing drum, and improper position of the hopper slide. Therefore, it is recommended that you should check and maintain regularly. Follow us https://www.zishangliaojiaobanji.cn , take you to learn more about relevant matters!
