详讲搅拌车液压系统噪音产生原因及排除方法
在工作过程中，司机朋友们时常会遇到搅拌车发出严重噪音的情况，查询才知，是液压系统发出来的，液压系统为什么会发出严重噪音呢？又该如何去？下面全自动搅拌车厂家为大家分享。
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、油箱内油量不足，吸油口或排油口露出油面，有空气进入系统中，吸油管侵入油中太浅，油箱透气不良。
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、吸油管的接头漏气。
2. The joint of the oil suction pipe is leaking.
3、吸油口处滤清器堵塞，油泵空转，吸油管有急弯，使吸油不足或不畅。
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、油泵转速过高，造成吸空。
4. The oil pump speed is too high, causing suction.
5、油泵本身质量差，如齿轮泵的齿形误差较大，叶片泵的叶片卡住等都将引起噪音。
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、阀类元件技术状况不良，如阀芯与阀体配合不良，表面拉毛，油液中的杂质将阀孔堵塞，阀中弹簧疲劳或损坏，使阀芯动作不灵引起噪音。
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、管路过细、过长，安装固定不良，引起振动而产生噪音。
7. The pipeline is too thin and too long, and the installation and fixation are poor, causing vibration and noise.
8、油路系统中有堵塞物，使油流不畅。
8. There is blockage in the oil circuit system, which makes the oil flow blocked.
（2）排除方法
(2) Exclusion method
1、将油箱内油液加规定高度，吸油管插入约2/3深度处为宜。
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、检查油管接头，并拧紧或更换。
2. Check the oil pipe connector and tighten or replace it.
3、清洗滤清器，急弯，将吸油口切成45°切口，增加吸油面积。
3. Clean the filter, eliminate sharp bends, cut the oil suction port into a 45 ° cut, and increase the oil suction area.
4、调整油泵规定转速。
4. Adjust the oil pump to the specified speed.
5、如油泵齿轮或叶片有问题，应检查修理或更换。
5. If the oil pump gear or blade is defective, check, repair or replace it.
6、选好管路适宜的管径，并安装固定好。
6. Select the appropriate pipe diameter of the pipeline, and install and fix it.
7、检查修复或更换阀类元件。
7. Check and repair or replace valve components.
8、检查清洗，疏通油路。
8. Check and clean, and dredge the oil path.
