For the concrete mixer truck, because of its high price, it is worthy of special attention. However, although the concrete mixer is made of steel, it also has a life cycle just like people. In the period of divergence, the physical condition of the mixer is very different.

混凝土自动上料搅拌车的使用周期及寿命是多少年，我们将周期划分为期、微软期、更年期、暮年期和危险期五个阶段。在这五个阶段，对混凝土搅拌车的保养、维修上也各不一样。

How many years is the service life and service life of the automatic concrete feeding mixer? We divide the cycle into five stages: peak period, Microsoft period, menopause period, twilight period and dangerous period. In these five stages, the maintenance and repair of concrete mixer truck are also different.

1~2年期，混凝土搅拌车使用的前两年，是生命的期，可以说是混凝土搅拌车使用状况的时分，相当于人的青年期。这个期间的人满怀热情、敢闯敢做，似乎不会倦怠。

The peak period of 1-2 years, the first two years of the use of concrete mixer truck is the peak period of life, which can be said to be the best time for the use of concrete mixer truck, which is equivalent to the youth period of people. During this period, people are full of enthusiasm and dare to do something, and they don't seem to be tired.

处于这个期间的混凝土搅拌车也是如此，车况极好，只需保持惯例保养，根本上不会有什么问题，但有些质量不怎么过硬水泥搅拌车，期只能对峙一年左右。所以，新车年行使进程中根本不会出什么大的质量问题，然则运用两年以上的混凝土搅拌车就要逐步初步改换一些易损耗的部件。

The concrete mixer truck in this period is also the same. The condition of the truck is excellent. As long as the routine maintenance is required, there will be no problem at all. However, some cement mixers are of poor quality, and the peak period can only last about one year. Therefore, the new car in the first year of driving process will not have any major quality problems, but the use of more than two years of concrete mixer truck will gradually change some of the most vulnerable parts.

2~4年微软期，这个阶段，混凝土搅拌车初步进入了微软期。不再像前期那样龙精虎猛。这个期间的混凝土搅拌车，需求常常改换一些部件，给其增补能量。起首需求改换新的刹车皮。刹车皮是驾驶平安的首道防地。依据阅历，刹车皮大约在两年左右就会磨荆此时，燃油泵也差不多该清洗或改换。假定混凝土搅拌车跑起来不安宁稳，就应该反省车子的减振器。假定减振器的弹簧落空弹性，下雨天行驶就十分风险。

2-4 years of Microsoft period. At this stage, the concrete mixer truck has initially entered the Microsoft period. It's not as vigorous as it was in the early days. During this period, the concrete mixer needs to change some parts to supplement energy. At first, new brake pads were needed. The brake skin is the first defense for safe driving. According to experience, the brake skin will wear in about two years. At this time, the fuel pump should be cleaned or replaced. Assuming that the concrete mixer runs restlessly and stably, we should reflect on the shock absorber of the truck. Assuming that the spring of the shock absorber is elastic, driving on rainy days is very risky.

沙和砾石是混凝土的主要组成成分。它们使混凝土贮罐及进、出料口在工作时磨损严重。由于每个厂家罐体制造材料不同其工作寿命则大不相同。

Sand and gravel are the main components of concrete. They make the concrete storage tank and the inlet and outlet wear seriously. Due to the different manufacturing materials of the tank body of each manufacturer, its working life is quite different.
