When some customers purchase concrete mixer, they think that the larger the volume of mixer is, the better, the more economical and efficient. Although in theory, this concept is right, in practice, the larger the volume is, the larger the tank is.

罐體容積大不僅影響購車的本錢，還影響車輛功能，行車系數(shù)低，罐體越大越高，車輛穩(wěn)定性差。所以車主朋友們應(yīng)根據(jù)拌和車作業(yè)的工況環(huán)境，經(jīng)濟效益，功能、等多方面因素選擇適宜的混凝土拌和車。

The large volume of the tank not only affects the cost of the car, but also affects the function of the car. The driving safety factor is low. The larger the tank, the higher the center of gravity, and the worse the stability of the car. Therefore, the owners and friends should select the appropriate concrete mixer according to the working conditions, environment, economic benefits, functions, safety and other factors.

那么究竟對于混凝土拌和車容積該怎么選？混凝土拌和車容積不能簡單的以為就是罐體的容積，要有清晰的三個概念區(qū)別：

So how to choose the volume of concrete mixer? First of all, the volume of concrete mixer can't be simply considered as the volume of tank body. There should be three clear conceptual differences:

拌和車幾何容積：拌和桶內(nèi)實踐的幾何容積，是指拌和罐設(shè)，用數(shù)學(xué)方法核算出來的幾何容積。

Geometric volume of mixing truck: the practical geometric volume in mixing drum refers to the geometric volume calculated by mathematical method during the design of mixing drum.

拌和動容積：拌和車可以運送的預(yù)拌混凝土量（以搗實后的體積計）。可以看成拌和車抵達工程現(xiàn)場所可以卸下的混凝土方量預(yù)拌混凝土容量按2400kg/m3核算。

Mixing dynamic volume: the amount of ready mixed concrete that can be transported by the mixer (calculated by the volume after compaction). It can be seen that the volume of ready mixed concrete that can be unloaded when the mixer arrives at the project site is 2400KG / m3.

拌和容積：拌和車置于水平位置，拌和桶能容納的未經(jīng)拌和的混凝土物料（包括水），并能拌和出運混凝土的量（以搗實后的體積計）。

Mixing volume: the mixer shall be placed in a horizontal position, and the mixing barrel shall be able to hold the largest amount of concrete materials (including water) that have not been mixed, and can be mixed and transported to the concrete volume (calculated by the volume after compaction).

三者的關(guān)系應(yīng)該是：拌和車幾何容積＞拌和容積＞拌和動容積，用戶經(jīng)常所說的容積應(yīng)該是指攪動容積，所以在現(xiàn)購拌和車時，要注意區(qū)別問清車輛的拌和容積。

The relationship between the three should be: the geometric volume of the mixer > the mixing volume > the mixing dynamic volume. The volume that users often say should refer to the mixing volume. Therefore, when purchasing the mixer, pay attention to the difference between the mixing volume of the vehicle.
