As a transport vehicle, self loading mixer must comply with the maintenance and repair regulations of the Ministry of communications. Combined with the actual situation of concrete mixer, maintenance and repair are carried out. In terms of daily maintenance, in addition to the maintenance of the self loading mixer engine and chassis, the following maintenance work must be carried out for the self loading mixer.

一，合理确定保护周期：自上料搅拌车保护周期是指汽车保护的距离或时间。在实际应用过程中，车主应参考汽车制造商介绍的保护周期，联系汽车自身的技术和应用前提，并对保护周期进行适当调整。一般来说，新车在优越路况的前提下使用，没有必要过于频繁地保护，并且制造商规则的保护周期可以作为上限。如果汽车技能差，或前提不好，应适当缩短保护周期。

1、 Reasonably determine the protection period: the protection period of self loading mixer refers to the distance or time of vehicle protection. In the process of practical application, the owner should refer to the protection period introduced by the automobile manufacturer, contact the technology and application premise of the vehicle itself, and adjust the protection period appropriately. Generally speaking, it is not necessary to protect new cars too frequently when they are used under the premise of superior road conditions, and the protection period specified by the manufacturer can be used as the upper limit. If the vehicle skill is poor or the premise is not good, the protection period should be appropriately shortened.

二，测试的充分应用：自上料搅拌车制造商的自由检测运动往往有利于车主的长度，车主可以应用这些测试活动对车进行特定的体检，找出并一些潜在的问题实时，然后节省需求可以在将来呈现的高维护和保护成本。

2、 The full application of free testing: the free inspection campaign from the manufacturer of the loading mixer is often beneficial to the length of the owner. The owner can use these testing activities to carry out specific physical examination on the vehicle, find and eliminate some potential problems in real time, and then save the high maintenance and protection costs that can be presented in the future.

三，尽可能坍塌的修理组件：很多自上料搅拌车的拥有者都有这种感觉，就像汽车组件在坍塌后的维修将是不可阻挡的，这样车辆进入维修期太早。这种场景的原因是要了解修理工的装配技巧和质量。因此，是防止碰撞修复组件，应用各种类型的技能保护装备和技巧，保护自上料搅拌车免于拆卸，防止损坏自上料搅拌车组件和部件，提高保护质量，进而减少维护总成本。

3、 Repair components that collapse as much as possible: many owners of self loading mixers have this feeling, just like the repair of automobile components after collapse will be unstoppable, so the vehicle enters the maintenance period too early. The reason for this scenario is to first understand the assembly skills and quality of the repairman. Therefore, it is better to prevent collision and repair components, apply various types of advanced skills to protect equipment and skills, protect self loading mixer from disassembly, prevent damage to components and parts of self loading mixer, improve protection quality, and reduce total maintenance cost.

除了上述知识之外，在通过混凝土搅拌输送混凝土之后，通常用水清洗混合筒的内部以防止硬化的混凝土占据空间，并且混合筒的体积越来越小。设备的合理运行和维护工作可以有效地防止设备在施工过程中的良好性能。

In addition to the above knowledge, after conveying concrete through concrete mixing, the interior of the mixing cylinder is usually cleaned with water to prevent hardened concrete from occupying space, and the volume of mixing cylinder is getting smaller and smaller. The reasonable operation and maintenance of the equipment can effectively prevent the good performance of the equipment in the construction process.
