对混凝土搅拌车有一些了解的朋友们都知道，车辆的专用机构主要包括取力器、搅拌筒前后支架、减速机、液压系统、搅拌筒、操纵机构、清洗系统等。那么我们究竟应该如何对于平口混凝土搅拌车容积选择呢？搅拌车容积大小不能简单的认为就是罐体的容积大小，要有明确的三个概念区分，一起来详细了解一下吧。

Friends who know something about concrete mixing truck know that the special mechanism of the truck mainly includes power take-off, front and rear supports of mixing drum, reducer, hydraulic system, mixing drum, operating mechanism, cleaning system, etc. So how should we choose the volume of concrete mixer truck? First of all, the volume of the mixer can not be simply considered as the volume of the tank. There should be a clear distinction between the three concepts. Let's have a detailed understanding.

混凝土搅拌车罐体越大重 心越高，车辆稳定性差，所以车主朋友们应根据搅拌车作业的工况环境，经济效益，性能、等多方面因素选择合适的混凝土搅拌车。

The bigger the tank, the higher the center of gravity, and the worse the stability of the truck. Therefore, the owners should choose the right truck according to the working conditions, economic benefits, performance, safety and other factors of the truck.

有些车主鉴于一直以来的习惯，一直有一种错误的观念，在购买平口混凝土搅拌车时，觉得搅拌车的容积是越大越好，经济。虽然从理论上来说，这种观念是对的，但实际上，选购使用并搅拌如此，容积大必然也就罐体越大。罐体容积大不仅影响购车的成本，还影响车辆性能，行车系数低，混凝土搅拌车罐体越大越高，车辆稳定性差，所以车主朋友们应根据搅拌车作业的工况环境，经济效益，性能、等多方面因素选择合适的混凝土搅拌车。

In view of their long-standing habit, some car owners have a wrong idea that the larger the volume, the better the economy. Although theoretically, this idea is right, in fact, the larger the volume, the larger the tank. Large tank volume not only affects the cost of car purchase, but also affects the performance of the car. The driving safety factor is low. The larger the tank body of the concrete mixer, the higher the center of gravity, and the poor stability of the car. Therefore, the car owners should choose the appropriate concrete mixer according to the working conditions, economic benefits, performance, safety and other factors of the mixer.
          

1、搅拌车几何容积：搅拌桶内实际的几何容积，是指搅拌罐设。用数学方法计算出来的几何容积。

1. Geometric volume of mixing truck: the actual geometric volume in the mixing drum, which refers to the design of mixing tank. The geometric volume calculated by mathematical method.

2、搅拌动容积：混凝土搅拌车能够运输的预拌混凝土量（以捣实后的体积计）。可以看成搅拌车到达工程现场所能够卸下的混凝土方量预拌混凝土容量按2400kg/m3计算。

2. Mixing volume: the volume of ready mixed concrete that can be transported by concrete mixer truck (based on the volume after tamping). It can be regarded as the volume of concrete that can be unloaded when the mixer arrives at the project site, and the capacity of ready mixed concrete is calculated as 2400KG / m3.

3、搅拌容积：混凝土搅拌车置于水平位置。搅拌桶能容纳较大的未经搅拌的混凝土物料。并能搅拌出运混凝土的量（以捣实后的体积计）。

3. Mixing volume: the concrete mixer truck is placed in the horizontal position. The mixing drum can hold large amount of concrete without mixing. It can also be used to mix the amount of concrete transported to the site (based on the volume after tamping).

三者的关系应该是：平口混凝土搅拌车几何容积>搅拌容积>搅拌动容积。用户经常所说的容积应该是指搅动容积。所以在现购搅拌车时，要注意区分问清车辆的搅拌容积。

The relationship among them should be: geometric volume > mixing volume > mixing volume. The volume often mentioned by users should refer to agitation volume. So in the cash mixer, we should pay attention to distinguish the mixing volume of the vehicle.
