如何全自動攪拌車系統發出的噪音？

全自動攪拌車正常的噪音是沒有問題的，但如果攪拌車發生不正常的噪音，那就是車輛的某個部位出現問題了，在全自動攪拌車，液壓系統出現異常噪音比較多，一起來看看攪拌車液壓系統的噪音辦法。攪拌車液壓系統發生噪音主要是先導閥功能不穩定造成的，就是先導閥前腔壓力高頻振動引起空氣振動而產生的噪音。全自動攪拌車液壓溢流閥引發噪音的原因及辦法：

There is no problem with the normal noise of the full-automatic mixer, but if there is abnormal noise in the mixer, it is a problem in some part of the vehicle. In the full-automatic mixer, there are more abnormal noises in the hydraulic system. Let's take a look at the noise solutions of the hydraulic system of the mixer. The noise of the mixer hydraulic system is mainly caused by the unstable function of the pilot valve, which is the noise caused by the air vibration caused by the high frequency vibration of the pressure in the front chamber of the pilot valve. Causes and solutions of noise caused by hydraulic relief valve of automatic mixer truck

1. 油液中混入空氣，在先導閥前腔內形成氣穴現象而引發高頻噪音，此時要做的就是及時的排盡空氣并避免外界空氣的進入。

1. When air is mixed into the oil, cavitation will be formed in the front cavity of the pilot valve, which will cause high-frequency noise. At this time, what we need to do is to exhaust the air in time and avoid the entry of external air.

2. 針閥在使用過程中因頻頻敞開而過度磨損，使針閥錐面與閥座不能密合，形成先導流量不穩定，產生壓力波動而引發噪音，此時應及時修理或者替換針閥。

2. The needle valve is excessively worn due to frequent opening in the process of use, so that the cone surface of the needle valve and the valve seat can not be closed, resulting in unstable pilot flow, pressure fluctuation and noise. At this time, the needle valve should be repaired or replaced in time.

3. 先導閥因彈簧疲勞變形形成其調壓功能不穩定，使得壓力波動大而引發噪音，此時需要更換彈簧。

3. The pressure regulating function of the pilot valve is unstable due to the fatigue deformation of the spring, which makes the pressure fluctuate greatly and causes noise. At this time, the spring needs to be replaced.

全自動攪拌車液壓油缸噪音原因及辦法：

Causes and solutions of hydraulic cylinder noise of automatic mixer truck:

1. 油液中混入空氣或者液壓缸中空氣未徹底排盡，在高壓效果下產生氣穴現象而引發較大噪音，此時應盡快排盡空氣。

1. The air in the oil or the air in the hydraulic cylinder is not completely exhausted, resulting in cavitation under the high pressure effect and causing large noise. At this time, the air should be exhausted as soon as possible.

2. 缸頭油封過緊或活塞桿彎曲，在運行過程中也會因為別勁而產生噪音，此時必須更換油封或者校正活塞桿。

2. If the oil seal of the cylinder head is too tight or the piston rod is bent, the noise will be produced due to other force during operation. At this time, the oil seal must be replaced or the piston rod must be corrected.
