Cement, fly ash, mineral powder and other powder materials are usually used to produce concrete. Most of these powder materials are stored in the cement silo of automatic mixer truck, which is rainproof and moisture-proof. Generally, when purchasing mixing plant facilities, it is equipped with automatic mixer, and a reasonable number of cement silos are matched with your production needs.

日常使用的自动搅拌车水泥仓也比较简单，但在使用过程中，生产的影响是材料的管理，如材料过多，过少，导致材料破裂或缺乏。因此，典型水泥筒仓中更重要的部件是液位计。水泥仓用于避免爆炸和材料短缺。

Daily use of automatic mixer cement silo is also relatively simple, but in the process of use, the impact of production is the management of materials, such as too much or too little material, resulting in material rupture or lack. Therefore, the more important component in a typical cement silo is the level gauge. Cement silo is used to avoid explosion and material shortage.

自动搅拌车的水泥仓液位计大多采用开关式液位计，安装在水泥筒仓的底部。它具有结构合理，性能可靠，安装简单，性价比高的特点。简单地说，当粉末仓中的材料位置低于设定的下限或负荷高于设定的上限时，将发出警报信号以提示操作者执行相应的处理。

The liquid level meter of cement silo of automatic mixer mostly adopts switch type liquid level meter, which is installed at the bottom of cement silo. It has the characteristics of reasonable structure, reliable performance, simple installation and high cost performance. In short, when the material position in the powder bin is lower than the set lower limit or the load is higher than the set upper limit, an alarm signal will be issued to prompt the operator to carry out the corresponding processing.

水泥仓液位计的工作原理如下：

The working principle of liquid level gauge in cement silo is as follows:

AC微电机在减速后驱动叶片旋转或振荡。当检测到的材料上升到叶片的位置时，叶片作用被阻挡，并且检测机构的主轴产生旋转位移。该位移产生微动开关动作，输出切换信号，然后另一个微动开关操作以切断电动机的电源以停止操作。只要仓库中的物料级别保持不变，此状态将继续。

The AC micromotor drives the blades to rotate or oscillate after deceleration. When the detected material rises to the position of the blade, the effect of the blade is blocked, and the spindle of the detection mechanism generates rotation displacement. The displacement first generates a micro switch action, outputs a switching signal, and then another micro switch operates to cut off the power supply of the motor to stop the operation. This status will continue as long as the item level in the warehouse remains unchanged.

当材料降低时，叶片阻力消失，测量装置通过弹簧的张力返回到原始状态，并且控制电动机电源的微动开关以打开电动机并旋转。随后，另一个微动开关操作以输出切换信号，只要没有材料阻挡检测叶片的旋转，该切换信号将保持不变。弹簧的张力可以根据不同比重的材料进行调节。当比率大时，弹簧的张力可以非常强烈地调节，反之亦然。

When the material is reduced, the blade resistance disappears, the measuring device returns to the original state through the spring tension, and controls the micro switch of the motor power supply to turn on the motor and rotate. Then, another micro switch operates to output a switching signal, which will remain unchanged as long as there is no material blocking the rotation of the detection blade. The tension of the spring can be adjusted according to the material with different specific gravity. When the ratio is large, the spring tension can be adjusted very strongly, and vice versa.
