詳講攪拌車液壓系統噪音產生原因及排除方法
在工作過程中，司機朋友們時常會遇到攪拌車發出嚴重噪音的情況，查詢才知，是液壓系統發出來的，液壓系統為什么會發出嚴重噪音呢？又該如何去解決？下面全自動攪拌車廠家為大家分享。
In the process of work, the driver friends often encounter serious noise from the mixer. After inquiry, they know that it is from the hydraulic system. Why does the hydraulic system make serious noise? How to solve it? The manufacturer of automatic mixer truck will share with you.
（1）原因
(1) Reason
1、油箱內油量不足，吸油口或排油口露出油面，有空氣進入系統中，吸油管侵入油中太淺，油箱透氣不良。
1. The oil quantity in the oil tank is insufficient, the oil suction port or oil discharge port is exposed to the oil surface, air enters the system, the oil suction pipe is too shallow in the oil, and the oil tank is poorly ventilated.
2、吸油管的接頭漏氣。
2. The joint of the oil suction pipe is leaking.
3、吸油口處濾清器堵塞，油泵空轉，吸油管有急彎，使吸油不足或不暢。
3. The filter at the oil suction port is blocked, the oil pump is idling, and the oil suction pipe has sharp bends, resulting in insufficient or unsmooth oil suction.
4、油泵轉速過高，造成吸空。
4. The oil pump speed is too high, causing suction.
5、油泵本身質量差，如齒輪泵的齒形誤差較大，葉片泵的葉片卡住等都將引起噪音。
5. The poor quality of the oil pump itself, such as the large tooth profile error of the gear pump and the seizure of the blade of the vane pump, will cause noise.
6、閥類元件技術狀況不良，如閥芯與閥體配合不良，表面拉毛，油液中的雜質將閥孔堵塞，閥中彈簧疲勞或損壞，使閥芯動作不靈引起噪音。
6. The valve components are in poor technical condition, such as the valve core and valve body are poorly matched, the surface is roughened, the valve hole is blocked by impurities in the oil, and the spring in the valve is tired or damaged, which makes the valve core act inefficiently and causes noise.
7、管路過細、過長，安裝固定不良，引起振動而產生噪音。
7. The pipeline is too thin and too long, and the installation and fixation are poor, causing vibration and noise.
8、油路系統中有堵塞物，使油流不暢。
8. There is blockage in the oil circuit system, which makes the oil flow blocked.
（2）排除方法
(2) Exclusion method
1、將油箱內油液加至規定高度，吸油管插入約2/3深度處為宜。
1. Add the oil in the oil tank to the specified height, and insert the oil suction pipe about 2/3 of the depth.
2、檢查油管接頭，并擰緊或更換。
2. Check the oil pipe connector and tighten or replace it.
3、清洗濾清器，消除急彎，將吸油口切成45°切口，增加吸油面積。
3. Clean the filter, eliminate sharp bends, cut the oil suction port into a 45 ° cut, and increase the oil suction area.
4、調整油泵至規定轉速。
4. Adjust the oil pump to the specified speed.
5、如油泵齒輪或葉片有問題，應檢查修理或更換。
5. If the oil pump gear or blade is defective, check, repair or replace it.
6、選好管路適宜的管徑，并安裝固定好。
6. Select the appropriate pipe diameter of the pipeline, and install and fix it.
7、檢查修復或更換閥類元件。
7. Check and repair or replace valve components.
8、檢查清洗，疏通油路。
8. Check and clean, and dredge the oil path.
