Method for reducing noise of self feeding concrete mixer

1、濾芯堵塞造成吸油困難或不足；清洗或更換濾芯。

1. Oil absorption is difficult or insufficient due to clogged filter element; Clean or replace the filter element.

2、工作油液不合要求或油液粘度太大；更換低粘度的液壓油。

2. The working oil does not meet the requirements or the oil viscosity is too high; Replace the hydraulic oil with low viscosity.

3、油箱液面太低，油面上空氣被吸入泵內；補加相同標號的液壓油。

3. The liquid level of the oil tank is too low, and the air on the oil level is sucked into the pump; Add hydraulic oil of the same grade.

4、吸油管路進氣或堵塞；檢查擰緊，不要吸進空氣。

4. Intake or blockage of oil suction pipeline; Check the tightening and do not breathe in air.

5、泵的安裝支架的剛性不足，工作時會產生震動和噪音；加固支架。

5. The rigidity of the mounting bracket of the pump is insufficient, which will produce vibration and noise during operation; Reinforce the support.

6、輸入法蘭與萬向傳動軸的連接、萬向傳動軸與取力器的連接角度過大、松動時會產生噪音；檢查緊固。

6. The connection between the input flange and the universal drive shaft and the connection angle between the universal drive shaft and the power take-off are too large and loose, which will produce noise; Check the fastening.

7、罐體內有粘結的混凝土存料，要清鏟干凈。

7. There are bonded concrete storage materials in the tank, which shall be cleared.

當我們所操作運行的自自進料混凝土攪拌車在使用過程中如果壽司出現噪音的話應仔細檢查其產生的原因，并采取相應的措施，以免小毛病拖成大毛病。同時，在平常的使用中也要做好對車輛的維護以及保養工作，能夠有效避免各種故障的發生。

When the self feeding concrete mixer operated by us is in use, if there is noise in sushi, we should carefully check the causes and take corresponding measures to avoid small problems from dragging into big problems. At the same time, in normal use, we should also do a good job in the maintenance of the vehicle, which can effectively avoid the occurrence of various faults.
