1. What should be paid attention to when driving automatic concrete mixer truck?

驾驶自动混凝土搅拌机，为经验丰富的驾驶员，具备驾驶的一般知识。这里要提醒的是，因为混凝土是流态的，车辆行驶时遇弯道，必须降低速度，以免混凝土不稳定产生的离心力使车辆不稳!

Driving automatic concrete mixer, experienced driver with general knowledge of safe driving. What should be reminded here is that, because the concrete is in flow state, the vehicle must reduce its speed when it encounters a curve when driving, so as to avoid the centrifugal force produced by the instability of concrete to make the vehicle unstable!

2、混凝土自动搅拌车多装混凝土有哪些影响?

2. What are the effects of loading more concrete on the automatic mixer truck?

9方以下的混凝土自动搅拌车多装混凝土，在爬坡过程中会发生漏洒情况，12方搅拌车多装混凝土，搅拌会分层，混凝土砂率将偏低，石粒尺寸过大，到工地泵送石子多。

If more concrete is loaded into the automatic mixer truck with the volume of less than 9 cubic meters, leakage and sprinkling will occur in the process of climbing. If the mixer truck of 12 cubic meters is loaded with more concrete, the mixing will be layered, the sand ratio of concrete will be low, the size of stone particles will be too large, and there will be more stones pumped to the construction site.

3、新的混凝土自动搅拌车一般开几年后容易出问题。

3. The new automatic concrete mixer truck is easy to have problems after driving for several years.

一般来说，拉干料一般5年，拉湿料一般是7年。故障问题多发生在使用三年后，混凝土自动搅拌车容易出现问题，因此建议时常对设备进行保养，保养维护对延长混凝土自动搅拌车有很大作用。

Generally speaking, the dry material is generally 5 years, and the wet material is generally 7 years. Fault problems often occur after three years of use, and the automatic concrete mixer truck is prone to problems. Therefore, it is recommended to maintain the equipment from time to time, which has a great effect on extending the automatic concrete mixer truck.

4、混凝土凝固在混凝土自动搅拌车里怎么办?

4. How to do when the concrete solidifies in the concrete automatic mixer?

固化后，混凝土的主要成分为硅酸二钙和硅酸三钙。理论上，盐酸可以与之反应以去除其固体形状。但在实际操作中，由于混合器的物料口很小，盐酸的用量难以控制，盐酸也可以与搅拌车罐体发生反应，因此操作难度很大。事实上，这种情况发生后，往往使用电焊或气割切割罐体，

After curing, the main components of concrete are dicalcium silicate and tricalcium silicate. In theory, hydrochloric acid can react with it to remove its solid shape. But in the actual operation, because the material port of the mixer is very small, the amount of hydrochloric acid is difficult to control, and the hydrochloric acid can react with the tank of the mixer, so the operation is very difficult. In fact, when this happens, the tank body is often cut by electric welding or gas cutting,

然后将凝固的混凝土进行破碎时。

Then, the solidified concrete is crushed.

5、混凝土自动搅拌车上装指的是什么?

5. What is the meaning of loading on automatic concrete mixer truck?

搅拌车上装是指底盘挡泥板以外的东西，包括混合罐本体和支架、进出料斗、液压系统和减速机、水箱和管路、操作连杆机构等。

The top loading of mixer truck refers to the things outside the mudguard of chassis, including mixing tank body and bracket, inlet and outlet hopper, hydraulic system and reducer, water tank and pipeline, operating linkage mechanism, etc.

6、普通混凝土自动搅拌车的液压系统是国产的还是进口的?

6. Is the hydraulic system of ordinary concrete mixer made in China or imported?

根据车辆的尺寸和客户的需要，一般6方以下制造商配备国内系统(可选进口)，6方以上标配是进口系统。

According to the size of the vehicle and the needs of customers, generally, manufacturers less than 6 parties are equipped with domestic system (optional import), and the standard configuration of more than 6 parties is imported system.

7、小方量搅拌车的液压泵是选择定量泵还是变量泵?

7. Is the hydraulic pump of small volume mixer choose quantitative pump or variable pump?

液压泵是搅拌车的主要部件。一般来说，搅拌车低于6方标准配置是定量泵，但建议客户安装变量泵。

The hydraulic pump is the main part of the mixer. Generally speaking, the mixer truck is less than 6 square meters, and the standard configuration is a fixed pump, but the customer is advised to install a variable pump.

8、搅拌机的焊接工艺是什么?

8. What is the welding process of mixer?

目前，一般厂家对整车焊接采用自动无缝焊接，环缝和纵缝采用自动无缝焊接。

At present, general manufacturers use automatic seamless welding for vehicle welding, and automatic seamless welding is used for circumferential seam and longitudinal seam.

9、混凝土自动搅拌车的付款方式是什么样的?

9. What is the payment method for the concrete mixer truck?

混凝土自动搅拌车有多种付款方式，可以全额或分期付款。一般来说，厂家对全额付款会有一定的优惠，但分期付款没有优惠，利息和银行一样。

Automatic concrete mixer has many payment methods, which can be paid in full or in installments. Generally speaking, the manufacturer will have certain preferential treatment to the full payment, but the installment payment does not have the preferential treatment, the interest and the bank are the same.

10、如果混凝土自动搅拌车很难出料怎么办?有没有比加水更好的方法?

10. What should I do if it is difficult for the concrete mixer to discharge? Is there a better way than adding water?

如果是混凝土坍落度太小或混凝土强度太高，混凝土太黏不好下的原因，可根据施工要求适当调整混凝土，如果不总是好，应考虑叶片角度和出料口是否存在问题。

If the concrete slump is too small or the concrete strength is too high, and the concrete is too sticky, the concrete can be adjusted according to the construction requirements. If it is not always good, the blade angle and outlet should be considered.
