Nowadays, many special-purpose vehicles are equipped with power steering. Power steering can make driving easier for the driver, and power steering is also available on the mixer. As one of the parts of the mixer, power steering can not avoid one kind of fault. What faults are prone to occur in the power steering of the mixer? Let's have a look.

1. 搅拌车动力转向在使用过程中会出现转向里不足或者不均匀。

1. the power steering of the mixer truck may be insufficient or uneven during use.

2. 混凝土搅拌车油泵驱动皮带松紧度不合适。

2. the tightness of the oil pump drive belt of the concrete mixer truck is inappropriate.

3. 油泵缸缺油，或有气泡，或有杂质阻塞。

3. the oil pump cylinder is short of oil, or has bubbles, or is blocked by impurities.

4. 搅拌车油泵保险阀座松脱，旁通阀卡住，泵油不足。

4. the safety valve seat of the oil pump of the mixer truck is loose, the bypass valve is stuck, and the pump oil is insufficient.

5. 定子和叶片的磨损过度，槽内有油污，叶片卡滞引起泵油压力不足。

5. excessive wear of stator and blade, oil stain in the groove, and insufficient pump oil pressure caused by stuck blade.

6. 齿轮啮合过松，使搅拌车转向盘转动时沉重。

6. the gear engagement is too loose, which makes the steering wheel of the mixer heavy when rotating.

7. 密封环因磨损或折断而漏油。

7. the sealing ring leaks oil due to wear or fracture.

8. 转向螺杆的轴承螺母松动。

8. the bearing nut of the steering screw is loose.

9. 油面过高，过滤网堵塞，集油管弯曲，或者衬套损坏，油从油泵通气阀处甩出，液压转向助力器有异响：搅拌车的油泵有声响，这是因为油液不足，皮带过松，系统中有空气，滤网堵塞，集油管弯曲，集流管下垫损坏和安装不当等引起的；搅拌车的转向助力器有冲击声响，主要是齿轮啮合过松，间隙过大引起的。

9. the oil level is too high, the filter screen is blocked, the oil collecting pipe is bent, or the bushing is damaged, the oil is thrown out from the vent valve of the oil pump, and the hydraulic steering booster has abnormal noise: the oil pump of the mixer truck has a sound, which is caused by insufficient oil, loose belt, air in the system, blocked filter screen, bent oil collecting pipe, damage to the bottom pad of the collecting pipe and improper installation; The steering booster of the mixer truck has impact sound, which is mainly caused by too loose gear engagement and too large clearance.

搅拌车在现代的社会建设中是不可或缺的一种专用车，使用范围广泛，建筑工程，一些大型项目的建设等都离不开搅拌车，搅拌车的使用大大提高了混凝土的质量，进而也提高了建筑物的质量。混凝土搅拌车运输车实惠，而且现在都是轻量化的设计，额定载质量大，购买是很划算的。

Mixer truck is an indispensable special vehicle in modern social construction. It is widely used. Construction projects and the construction of some large projects are inseparable from mixer truck. The use of mixer truck has greatly improved the quality of concrete and buildings. Concrete mixer trucks are affordable, and now they are all light-weight design, with large rated load, so it is very cost-effective to buy.
