正時皮帶是混凝土攪拌機一個非常關鍵的外部零件，它是否能夠正常使用也大大的影響著我攪拌機的使用，所以說需要定期更換正時皮帶，下面來講講它的保養事項吧！

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!

皮帶正時皮帶的主要作用是用來驅動發動機的配氣機構，使發動機的進、排氣門在適當的時候開啟或關閉，來保證發動機的汽缸能夠正常地吸氣和排氣。

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.

在有的車型中正時皮帶還負責驅動水泵?；炷翑嚢铏C的皮帶屬于橡膠部件，隨著發動機工作時間的增加，正時皮帶和正時皮帶的附件，如正時皮帶張緊輪、正時皮帶張緊器和水泵等都會發生磨損或老化。

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，凡是裝有正時皮帶的發動機，廠家都會有嚴格要求，在規定的周期內定期更換正時皮帶及附件，更換周期則隨著發動機的結構不同而有所不同，一般在混凝土攪拌機行駛到6萬~10萬時應該更換，具體的更換周期應該以混凝土攪拌機的保養手冊說明為準。

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.

此外要注意特種保養，這是混凝土攪拌機發生重大異常事件后進行的一種應對性維護保養，列如車輛發生了翻入河中的事故，當打撈出來后，如果機件沒有發生重大損壞，在重新使用前，需要進行一次應對性維護保養。

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.

又如發動機發生了飛車事故，當飛車被制止后，須對曲柄連桿機構及其他有關部位進行一次應對性維護保養，使這些部位零部件的技術狀態完全恢復正常后，才可以重新啟動運轉。

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.

以上就是混凝土攪拌機的正時皮帶保養方法，用車的同時也要注重保養，這樣才能增加他的壽命，更好地使用。關注我們http://www.tywlkj.cn，更多了解！
