Large tank volume not only affects the cost of car purchase, but also affects the vehicle performance. The driving safety coefficient is low. The larger the tank body is, the higher the center of gravity is, and the vehicle stability is poor. Therefore, the car owners should choose the appropriate concrete mixer truck according to the working conditions, environment, economic benefits, performance, safety and other factors.

混凝土攪拌車(chē)容積不能簡(jiǎn)單的認為就是罐體的容積，要有明確的三個(gè)概念區分：

First of all, the volume of concrete mixer truck can not be simply considered as the volume of tank, but should be distinguished by three clear concepts

攪拌車(chē)幾何容積：攪拌桶內實(shí)際的幾何容積，是指攪拌罐設計時(shí)，用數學(xué)方法計算出來(lái)的幾何容積。

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

攪拌動(dòng)容積：攪拌車(chē)能夠運輸的預拌混凝土量（以搗實(shí)后的體積計）?？梢钥闯蓴嚢柢?chē)到達工程現場(chǎng)所能夠卸下的混凝土方量預拌混凝土容量按2400kg/m3計算。

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

攪拌容積：攪拌車(chē)置于水平位置，攪拌桶能容納的未經(jīng)攪拌的混凝土物料（包括水），并能攪拌出運混凝土的量（以搗實(shí)后的體積計）。

Mixing volume: when the mixer truck is placed in a horizontal position, the mixing bucket can hold the largest amount of concrete materials (including water) that have not been mixed, and can mix the volume transported to the concrete (based on the volume after tamping).

三者的關(guān)系應該是：攪拌車(chē)幾何容積＞攪拌容積＞攪拌動(dòng)容積，用戶(hù)經(jīng)常所說(shuō)的容積應該是指攪動(dòng)容積，所以在現購攪拌車(chē)時(shí)，要注意區分問(wèn)清車(chē)輛的攪拌容積。

The relationship between the three should be: the geometric volume of the mixer truck > the mixing volume > the stirring volume. The volume often referred to by the user should refer to the stirring volume. Therefore, when purchasing the mixer truck, we should pay attention to distinguish the mixing volume of the vehicle.
