现在的专用车上很多都安装有动力转向的，动力转向可以让驾驶员开车更轻松，混凝土搅拌车上也有动力转向，动力转向作为搅拌车的零部件之一，也是避免不了会出现这样那样的故障的，混凝土搅拌一体车的动力转向容易出现哪些故障呢？一起来看一下吧。

Nowadays, many special vehicles are equipped with power steering. Power steering can make driving easier for drivers. Concrete mixer also has power steering. As one of the parts of mixer, power steering can't avoid such and such failures. What are the common failures of power steering of concrete mixer? Let's have a look.

1. 混凝土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。2. 混凝土搅拌车油泵驱动皮带松紧度不合适。3. 油泵缸缺油，或有气泡，或有杂质阻塞。4. 混凝土搅拌车油泵保险阀座松脱，旁通阀卡住，泵油不足。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。6. 齿轮啮合过松，使搅拌车转向盘转动时沉重。7. 密封环因磨损或折断而漏油。8. 转向螺杆的轴承螺母松动。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。
           

1. The power steering of concrete mixer truck will be insufficient or uneven in use. 2. The tightness of oil pump drive belt of concrete mixer truck is not suitable. 3. The oil pump cylinder is short of oil, or there are bubbles or impurities blocking. 4. The safety valve seat of concrete mixer pump is loose, the bypass valve is stuck, and the pump oil is insufficient. 5. Excessive wear of stator and blade, oil contamination in groove, blade sticking, resulting in insufficient pump oil pressure. 6. The meshing of gears is too loose, which makes the steering wheel of mixer heavy when it rotates. 7. The sealing ring leaks oil due to wear or fracture. 8. The bearing nut of the steering screw is loose. Nine 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 oil pump vent valve, and the hydraulic steering booster has abnormal sound: the oil pump of the mixer has sound, which is caused by insufficient oil, too 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 has impact The impact noise is mainly caused by too loose gear mesh and too large clearance.

混凝土搅拌一体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。

Concrete mixer truck is an indispensable special vehicle in modern social construction. It is widely used. Construction engineering and construction of some large projects are inseparable from mixer truck. The use of mixer truck greatly improves the quality of concrete, and further improves the quality of buildings. Concrete mixer truck is affordable, and now it is lightweight design, rated load mass is large, it is very cost-effective to buy.
