正時(shí)皮帶是混凝土攪拌機(jī)一個(gè)非常關(guān)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(jī)的使用，所以說(shuō)需要定期更換正時(shí)皮帶，下面來(lái)講講它的保養(yǎng)事項(xiàng)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(shí)皮帶的主要作用是用來(lái)驅(qū)動(dòng)發(fā)動(dòng)機(jī)的配氣機(jī)構(gòu)，使發(fā)動(dòng)機(jī)的進(jìn)、排氣門(mén)在適當(dāng)?shù)臅r(shí)候開(kāi)啟或關(guān)閉，來(lái)保證發(fā)動(dòng)機(jī)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(chē)型中正時(shí)皮帶還負(fù)責(zé)驅(qū)動(dòng)水泵。混凝土攪拌機(jī)的皮帶屬于橡膠部件，隨著發(fā)動(dòng)機(jī)工作時(shí)間的增加，正時(shí)皮帶和正時(shí)皮帶的附件，如正時(shí)皮帶張緊輪、正時(shí)皮帶張緊器和水泵等都會(huì)發(fā)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(shí)皮帶的發(fā)動(dòng)機(jī)，廠家都會(huì)有嚴(yán)格要求，在規(guī)定的周期內(nèi)定期更換正時(shí)皮帶及附件，更換周期則隨著發(fā)動(dòng)機(jī)的結(jié)構(gòu)不同而有所不同，一般在混凝土攪拌機(jī)行駛到6萬(wàn)~10萬(wàn)時(shí)應(yīng)該更換，具體的更換周期應(yīng)該以混凝土攪拌機(jī)的保養(yǎng)手冊(cè)說(shuō)明為準(zhǔn)。

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(yǎng)，這是混凝土攪拌機(jī)發(fā)生重大異常事件后進(jìn)行的一種應(yīng)對(duì)性維護(hù)保養(yǎng)，列如車(chē)輛發(fā)生了翻入河中的事故，當(dāng)打撈出來(lái)后，如果機(jī)件沒(méi)有發(fā)生重大損壞，在重新使用前，需要進(jìn)行一次應(yīng)對(duì)性維護(hù)保養(yǎng)。

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(fā)動(dòng)機(jī)發(fā)生了飛車(chē)事故，當(dāng)飛車(chē)被制止后，須對(duì)曲柄連桿機(jī)構(gòu)及其他有關(guān)部位進(jìn)行一次應(yīng)對(duì)性維護(hù)保養(yǎng)，使這些部位零部件的技術(shù)狀態(tài)完全恢復(fù)正常后，才可以重新啟動(dòng)運(yùn)轉(zhuǎn)。

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(jī)的正時(shí)皮帶保養(yǎng)方法，用車(chē)的同時(shí)也要注重保養(yǎng)，這樣才能增加他的壽命，更好地使用。關(guān)注我們http://www.wishnailspa.com，更多了解！
