Start a fully automatic concrete mixer and hydraulic system so that the momentum obtained by the pump is used to drive the hydraulic motor. The drainage pump starts almost automatically, switches to the cleaning state, and is ready to control the operation button. Drain water from the water tank, open the drain ball valve at the bottom of the water tank and wait for the water in the water tank to drain. Press the button to drain the system and observe the condition of the pump outlet. When the water supply stops flowing out of the pump outlet, the operation is completed and the water in the pump is completely discharged.

根据上述过程，全自动混凝土搅拌车的泵泵排出干净，冬天不怕泵的开裂。请注意，每次使用泵时，必须强制排水。否则，它将在一夜之间完全损坏，无法使用。此外，在全自动混凝土搅拌车的强制排水过程中，重要的是要注意泵出口。

According to the above process, the pump of the full-automatic concrete mixer is discharged clean, and the pump is not afraid of cracking in winter. Please note that every time the pump is used, it must be forced to drain. Otherwise, it will be completely damaged overnight and cannot be used. In addition, in the forced drainage process of automatic concrete mixer, it is important to pay attention to the pump outlet.

一、对保护周期做出合理的决定：汽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，车主需要参考汽车制造商介绍的保护周期，联系汽车的技能和应用假设，并适当调整保护周期。一般而言，新车在道路条件良好的前提下使用，不需要经常保护，可以用于制造商规则的保护周期。如果您的汽车技能较低或您的假设不好，则需要适当缩短保护周期。

1、 Make a reasonable decision on the protection period: the vehicle protection period refers to the distance or time of vehicle protection. In the process of practical application, the owner needs to refer to the protection cycle introduced by the automobile manufacturer, contact the skills and application assumptions of the automobile, and adjust the protection cycle appropriately. Generally speaking, new vehicles are used under the premise of good road conditions, do not need regular protection, and can be used for the protection cycle specified by the manufacturer. If your car skills are low or your assumptions are not good, you need to shorten the protection cycle appropriately.

二，测试的充分应用：全自动混凝土搅拌车制造商的自由检测行为往往有利于车主的长度，车主将这些测试活动应用于汽车的特定车身执行检查，实时查找和潜在问题，并节省需求将来可能会出现的高维护和保护成本。

2、 Full application of free testing: the free testing behavior of the manufacturer of full-automatic concrete mixer is often conducive to the length of the owner. The owner applies these testing activities to the specific body of the vehicle for inspection, finds and eliminates potential problems in real time, and saves the high maintenance and protection costs that may occur in the future.

三，尽可能地折叠修理组件：许多全自动混凝土搅拌车的拥有者具有这种感觉，使得在修理坍塌之后车辆组件不能停止，使得车辆过早地进入维护期。我有。这种场景的原因是触及装配技能和修理工的质量。因此，防止碰撞修复组件，应用各种的技能保护装备和技巧，以保护汽车免于拆卸，防止损坏汽车组件和部件，提高保护和维护质量好减少总费用。

3、 Fold the repair components as much as possible: many owners of automatic concrete mixer have this feeling, so that the vehicle components can not stop after the repair collapses, making the vehicle enter the maintenance period prematurely. I have. The reason for this scenario is that it first touches on the assembly skills and the quality of the repairman. Therefore, prevent collision and repair components, apply various advanced skills to protect equipment and skills, so as to protect the vehicle from disassembly, prevent damage to vehicle components and parts, improve the quality of protection and maintenance, and reduce the total cost.

除了上述知识外，混凝土通过全自动混凝土搅拌车输送后，通常用水冲洗混合筒内部，使硬化后的混凝土不占空间，搅拌筒的体积变得越来越小。设备的合理运行和维护可以有效地阻碍在建设备的良好性能

In addition to the above knowledge, after the concrete is transported by the automatic concrete mixer, the interior of the mixing drum is usually washed with water, so that the hardened concrete does not occupy space, and the volume of the mixing drum becomes smaller and smaller. Reasonable operation and maintenance of equipment can effectively hinder the good performance of equipment under construction
