有人咨詢過這樣的問題，小型混凝土攪拌車在工作中有時候會出現高噪音的情況，噪音的出現肯定不是偶然，一定存在某種原因所致，具體原因如下：

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、小型混凝土攪拌車油箱液位過低，并且油液中的空氣被吸入泵中。如果發生這種情況，您可以添加帶有相同類型的液壓油。

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、如果泵的安裝支架不牢固，在工作期間會產生振動和噪音。在這種情況下，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、堵塞的濾芯會使吸油困難或者不充分。這種情況下，一定要及時清潔濾芯或更換濾芯。

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、如果液壓油不符合要求或者是油太粘，請更換符合要求的低粘度液壓油。

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

5、小型混凝土攪拌車儲罐中有堅硬的混凝土。如果發生這種情況，及時清理并鏟除干凈。

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

6、萬向傳動軸之間的連接角度以及傳動軸與取力器之間的連接角度太大，如果松開會產生噪音，在這種情況下，請在時間內檢查并擰緊。

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.

小型混凝土攪拌車高噪聲的六點原因就是如此了，您對此可以認真作為參考看看！
