What should I pay attention to when driving a concrete mixer?
Driving concrete mixer, for experienced drivers, general knowledge of safe driving. What should be reminded here is that since the concrete is fluid, when the vehicle turns sharply, the speed must be reduced to avoid the centrifugal force generated by the concrete turning which makes the vehicle unstable!
What are the effects of more concrete in the mixer truck?
More concrete is loaded in the mixer truck of less than 9m3, and the truck will leak during climbing; more concrete is loaded in the mixer truck of 12m3, and the mixing will be layered, so the concrete sand rate is low, the stone particle size is too large, and more stones are pumped to the construction site.
It's easy to have problems when the new mixer drives for several years?
Generally, it takes five years to pull dry materials and seven years to wet materials. Generally, problems will occur in the mixer after three years. The problems of the mixer are closely related to personal maintenance and manufacturers.
What should I do when the concrete solidifies in the mixer?
After concrete solidification, its main components are dicalcium silicate and tricalcium silicate. In theory, hydrochloric acid can react with it to remove its solid shape. But in fact, it is difficult to operate, because the material mouth of the mixer is very small, the amount of hydrochloric acid is difficult to control, and hydrochloric acid can also react with the tank body of the mixer. In fact, such a situation often occurs when the tank body is cut by electric welding or gas cutting, and then the solidified concrete is mechanically broken.
What do you mean by the mixer?
The loading on the mixer refers to the things other than the chassis fender, including the mixing tank body and support, in and out hopper, hydraulic system and reducer, water tank and pipeline, operating linkage mechanism, etc.
Is the hydraulic system of general mixer made in China or imported?
Generally, the manufacturer will choose the mixer according to the size of the mixer and the customer's demand. The standard equipment below 6 square meters is the domestic system (optional import), and the standard equipment above 6 square meters is the imported system.
Is the hydraulic pump of small volume mixer good at selecting volume pump or variable displacement pump?
The hydraulic pump is the main component of the mixer truck. Generally, the mixer truck less than 6 square meters is the standard quantitative pump. However, it is recommended that the customer choose variable pump.
What is the welding process of the mixer?
At present, the general manufacturers use full-automatic seamless welding for the welding of the whole car, and full-automatic seamless welding for the circumferential and longitudinal seams.
What is the payment method of mixer truck?
There are many ways to pay for the mixer truck. You can buy the truck in full or pay in installments. Generally, the manufacturer will have a certain discount for the whole truck. There is no discount for the installment, and the interest is the same as the bank interest.
How to deal with the discharging difficulty of concrete mixer? Is there any better way except adding water?
If it is because of concrete, it is necessary to see whether the slump is too small, the concrete strength is too high, or the concrete is too sticky. The above reasons can be adjusted properly according to the construction requirements. If it is always not good, it is necessary to consider whether the blade angle and the blanking opening have problems
