正时皮带是混凝土搅拌机一个非常关键的外部零件，它是否能够正常使用也大大的影响着我搅拌机的使用，所以说需要定期更换正时皮带，下面来讲讲它的保养事项吧！

The timing belt is a very important external part of the concrete mixer. Whether it can be used normally also greatly affects the use of my mixer. Therefore, the timing belt needs to be replaced regularly. Now let's talk about its maintenance!

皮带正时皮带的主要作用是用来驱动发动机的配气机构，使发动机的进、排气门在适当的时候开启或关闭，来保证发动机的汽缸能够正常地吸气和排气。

The main function of the belt timing belt is to drive the valve distribution mechanism of the engine, so that the inlet and exhaust valves of the engine can be opened or closed at an appropriate time to ensure that the engine cylinders can normally breathe in and exhaust.

在有的车型中正时皮带还负责驱动水泵。混凝土搅拌机的皮带属于橡胶部件，随着发动机工作时间的增加，正时皮带和正时皮带的附件，如正时皮带张紧轮、正时皮带张紧器和水泵等都会发生磨损或老化。

In some models, the timing belt is also responsible for driving the water pump. The belt of concrete mixer is a rubber part. With the increase of engine working time, the timing belt and its accessories, such as timing belt tensioner, timing belt tensioner and water pump, will be worn or aged.

因此，凡是装有正时皮带的发动机，厂家都会有严格要求，在规定的周期内定期更换正时皮带及附件，更换周期则随着发动机的结构不同而有所不同，一般在混凝土搅拌机行驶到6万~10万公里时应该更换，具体的更换周期应该以混凝土搅拌机的保养手册说明为准。

Therefore, the manufacturer has strict requirements for engines equipped with timing belts. The timing belts and accessories should be replaced regularly within the specified period. The replacement period varies with the structure of the engine. Generally, the concrete mixer should be replaced when it runs 60000~100000 km. The specific replacement period should be subject to the maintenance manual of the concrete mixer.

此外要注意特种保养，这是混凝土搅拌机发生重大异常事件后进行的一种应对性维护保养，列如车辆发生了翻入河中的事故，当打捞出来后，如果机件没有发生重大损坏，在重新使用前，需要进行一次应对性维护保养。

In addition, special maintenance shall be paid attention to. This is a kind of coping maintenance for the concrete mixer after a major abnormal event. For example, if the vehicle has been overturned into the river, when it is salvaged, if there is no major damage to the machine parts, a coping maintenance shall be carried out before reuse.

又如发动机发生了飞车事故，当飞车被制止后，须对曲柄连杆机构及其他有关部位进行一次应对性维护保养，使这些部位零部件的技术状态完全恢复正常后，才可以重新启动运转。

For another example, in case of an engine runaway accident, when the runaway is stopped, the crank linkage mechanism and other relevant parts must be subject to a coping maintenance, so that the technical status of these parts can be completely restored to normal before restarting operation.

以上就是混凝土搅拌机的正时皮带保养方法，用车的同时也要注重保养，这样才能增加他的寿命，更好地使用。关注我们http://www.zkhntjbj.com，更多了解！
