罐體容積大不僅影響購車的成本，還影響車輛性能，行車安全系數(shù)低，罐體越大重心越高，車輛穩(wěn)定性差。所以車主朋友們應(yīng)根據(jù)攪拌車作業(yè)的工況環(huán)境，經(jīng)濟效益，性能、安全等多方面因素選擇合適的混凝土攪拌車。

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.

首先混凝土攪拌車容積不能簡單的認為就是罐體的容積，要有明確的三個概念區(qū)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

攪拌車幾何容積：攪拌桶內(nèi)實際的幾何容積，是指攪拌罐設(shè)計時，用數(shù)學(xué)方法計算出來的幾何容積。

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.

攪拌動容積：攪拌車能夠運輸?shù)念A(yù)拌混凝土量（以搗實后的體積計）?？梢钥闯蓴嚢柢嚨竭_工程現(xiàn)場所能夠卸下的混凝土方量預(yù)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：攪拌車置于水平位置，攪拌桶能容納最大的未經(jīng)攪拌的混凝土物料（包括水），并能攪拌出運至混凝土的量（以搗實后的體積計）。

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(yīng)該是：攪拌車幾何容積＞攪拌容積＞攪拌動容積，用戶經(jīng)常所說的容積應(yīng)該是指攪動容積，所以在現(xiàn)購攪拌車時，要注意區(qū)分問清車輛的攪拌容積。
