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

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 is an experienced driver with general knowledge of safe driving. Here to remind is, because the concrete is fluid, when the vehicle running into a curve, must reduce the speed, so as to avoid the centrifugal force caused by the instability of the concrete 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 in automatic concrete mixer?

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 the automatic concrete mixer truck of less than 9 cubic meters loads more concrete, leakage and spillage will occur during the climbing process. If the automatic concrete mixer truck of 12 cubic meters loads more concrete, the mixing will be layered, the concrete sand rate will be low, the stone particle size will be too large, and more stones will be 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 is easy to go wrong after 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, it takes 5 years to pull dry materials and 7 years to pull wet materials. Most of the faults occur after three years of use, and the automatic concrete mixer is prone to problems. Therefore, it is suggested to maintain the equipment from time to time, which plays a great role in extending the service life of the automatic concrete mixer.

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 automatic concrete 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 mixer material mouth is very small, the amount of hydrochloric acid is difficult to control, hydrochloric acid can also react with the mixer tank, so the operation is very difficult. In fact, when this happens, electric welding or gas cutting is often used to cut the can body,

然后将凝固的混凝土进行破碎时。

Then the solidified concrete is broken.

5、混凝土自动搅拌车上装指的是什么?

5. What is the loading point of the automatic concrete mixer?

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 beyond 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 with less than 6 cubic meters are equipped with domestic system (optional import), and those with more than 6 cubic meters are equipped with imported system as standard.

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 mixing truck a constant displacement pump or a variable displacement 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。

Hydraulic pump is the main part of mixer. Generally speaking, the mixer truck is less than 6 cubic meters, and the standard configuration is quantitative pump, but it is recommended that the customer install variable displacement 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, the general manufacturers use automatic seamless welding for vehicle welding, and automatic seamless welding 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 of concrete mixer?

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。

There are many kinds of payment methods for automatic concrete mixer, which can be paid in full or in installments. Generally speaking, the manufacturer will have a certain discount for full payment, but there is no discount for installment payment, and the interest is the same as that of the bank.

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. If the concrete mixer is difficult to discharge, what should we do? 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.
