有人咨询过这样的问题，小型混凝土搅拌车在工作中有时候会出现高噪音的情况，噪音的出现肯定不是偶然，一定存在某种原因所致，具体原因如下：

Someone has inquired about the problem that small concrete mixers sometimes make high noise during work. The noise must not be accidental, but it must be caused by some reason. The specific reasons are as follows:

1、小型混凝土搅拌车油箱液位过低，并且油液中的空气被吸入泵中。如果发生这种情况，您可以添加带有相同类型的液压油。

1. The oil tank level of small concrete mixer truck is too low, and the air in the oil is sucked into the pump. If this happens, you can add hydraulic oil with the same type.

2、如果泵的安装支架不牢固，在工作期间会产生振动和噪音。在这种情况下，可以加固油泵支架。

2. If the mounting bracket of the pump is not secure, vibration and noise will occur during operation. In this case, the oil pump bracket can be reinforced.

3、堵塞的滤芯会使吸油困难或者不充分。这种情况下，一定要及时清洁滤芯或更换滤芯。

3. Blocked filter element will make oil absorption difficult or insufficient. In this case, the filter element must be cleaned or replaced in time.

4、如果液压油不符合要求或者是油太粘，请更换符合要求的低粘度液压油。

4. If the hydraulic oil does not meet the requirements or the oil is too viscous, replace the qualified low viscosity hydraulic oil.

5、小型混凝土搅拌车储罐中有坚硬的混凝土。如果发生这种情况，及时清理并铲除干净。

5. There is hard concrete in the tank of small concrete mixer. If this happens, clean up and remove it in time.

6、万向传动轴之间的连接角度以及传动轴与取力器之间的连接角度太大，如果松开会产生噪音，在这种情况下，请在时间内检查并拧紧。

6. The connection angle between the universal drive shaft and between the drive shaft and the power take-off is too large. If it is loosened, it will make noise. In this case, please check and tighten it within a time.

小型混凝土搅拌车高噪声的六点原因就是如此了，您对此可以认真作为参考看看！
