In the use of concrete mixer, an indispensable important component is the dead concrete mixer host. According to different concrete mixer, the type of host control system used will be different, so how to select the system and host? This article will give you a brief introduction.

一、混凝土搅拌车主机控制系统的特点

1、 Characteristics of main engine control system of concrete mixer

混凝土搅拌车不同型号就拥有不同的控制系统，一般型号越大的混凝土搅拌车采用的控制系统就会越标准。各型号混凝土搅拌站与控制系统之间的关系式：

Different models of concrete mixer have different control systems. The larger the general model, the more standard the control system will be. The relationship between each type of concrete mixing plant and control system is as follows:

1、小型号混凝土搅拌车，包括：HZS25型混凝土搅拌站、HZS35型混凝土搅拌站、HZS50型混凝土搅拌站一般采用的是集中控制系统。

1. Small type concrete mixer, including HZS25 concrete mixing station, HZS35 concrete mixing station and HZS50 concrete mixing plant, generally adopts centralized control system.

但是也有采用标准控制系统，但是不常用，这就是为什么HZS25型混凝土搅拌站、HZS35型混凝土搅拌站、HZS50型混凝土搅拌站有两种不同的配置。

However, standard control system is also used, but it is not commonly used. This is why HZS25 concrete mixing station, HZS35 concrete mixing station and HZS50 concrete mixing station have two different configurations.

既有简易型混凝土搅拌车，也有标准型混凝土搅拌车。

There are both simple concrete mixer truck and standard concrete mixer truck.

2、中型混凝土搅拌车HZS90型混凝土搅拌车、中小型混凝土搅拌车：HZS60型混凝土搅拌车、HZS75型混凝土搅拌车一般采用的控制系统是标准控制系统。

2. Medium sized concrete mixer HZS90 concrete mixer, small and medium sized concrete mixer: HZS60 concrete mixer and HZS75 concrete mixer generally adopt standard control system.

操作要比小型号的集中控制系统方便许多。

The operation is much more convenient than the small type centralized control system.

3、而大型号混凝土搅拌站，包括：HZS120型混凝土搅拌车、HZS180型混凝土搅拌车、HZS240型混凝土搅拌车采用的控制系统都是标准控制系统、或者是全自动控制系统。

3. The control systems of large-scale concrete mixing stations, including HZS120 concrete mixer, HZS180 concrete mixer and hzs240 concrete mixer, are standard control systems or fully automatic control systems.

这就是不同型号的混凝土搅拌车采用的不同的控制系统的特点。

This is the characteristics of different control systems adopted by different types of concrete mixer.

二、混凝土搅拌车主机怎么选取

2、 How to select the main engine of concrete mixer

1、自落式与强制式的选取

1. Selection of self falling type and compulsory type

混凝土搅拌车以搅拌原理来划分可分为强制式和自落式两类。强制式的罐体不动，搅拌轴旋转，通过搅拌臂带动搅拌叶片对罐体内的物料进行强制导向搅拌。

According to the mixing principle, concrete mixer can be divided into forced type and self falling type. The forced tank body does not move, the mixing shaft rotates, and the stirring blade is driven by the mixing arm to conduct forced guided mixing for the materials in the tank body.

自落式拌筒旋转，借助安装在拌筒内的搅拌叶片，使物料抬起，物料靠自身重力跌落，并产生轴向串动，从而实现搅拌效果。

With the help of the mixing blade installed in the mixing drum, the material is lifted and the material falls by its own gravity, resulting in axial series movement, so as to realize the mixing effect.

两者相比，强制式的搅拌作用强烈，一般在30-60秒的搅拌时间就可将混合物拌成匀质性混凝土，制备专用或特种混凝土时，则需较长时间。

Compared with the two, the forced mixing effect is strong. Generally, the mixture can be mixed into homogeneous concrete in 30-60 seconds mixing time, and it takes a long time to prepare special or special concrete.

自落式的搅拌时间需翻倍甚更长，搅拌特种混凝土困难甚不可能。

It is difficult or even impossible to mix special concrete because the mixing time of self falling type needs to be doubled or even longer.

2、双卧轴与单卧轴的选取

2. Selection of double horizontal axis and single horizontal axis

强制式混凝土搅拌车可分为单卧轴和双卧轴两类。双卧轴与单卧轴型式相比，搅拌叶片的线速度低，耐磨损;罐体各部位衬板的磨损程度比较接近，衬板的使用寿命长，经济性好。

The forced concrete mixer can be divided into single horizontal shaft and double horizontal shaft. Compared with single horizontal shaft, double horizontal shaft has lower linear speed and wear resistance; the wear degree of lining plate in different parts of tank body is close, the service life of lining plate is long and the economy is good.

驱动装置可采用双套同步运行，更有利于大规格机型的配套条件和产品系列化发展，因此，双卧轴搅拌机成为应用广泛的搅拌站主机。

The driving device can use double sets of synchronous operation, which is more conducive to the matching conditions of large-scale models and the development of product series. Therefore, the double horizontal shaft mixer has become a widely used mixing station host.
