Users have been reflecting that the new automatic mixer truck has become heavier and heavier after being bought and used for a long time. How to solve this problem? Today, let's talk about what causes the mixer truck to become heavier and heavier? How to solve this situation?
1、 Quick loading and unloading is the key to prevent the tank from getting stuck
Bring water reducer with the vehicle
Water reducer is a kind of concrete admixture that can reduce the amount of water used for mixing under the condition of maintaining the concrete slump unchanged. It can be carried with the vehicle and can adjust the concrete well. However, when adding water reducing agent, it must be remembered that there are people in the laboratory of commercial concrete station, otherwise the concrete quality and strength are not enough, and the driver shall bear the consequences.
Return to the factory to check the water volume in the tank
When returning to the station after each trip, check the water volume in the water storage tank, so that the water in the water tank can be full at any time, in case of emergency.
Check the concrete quality before leaving the factory
The quality of each plate of concrete may vary due to different raw materials. When the concrete is loaded and leaving the site, it is necessary to check the slump and workability of the concrete in the tank, and be careful of the early setting of the concrete and the layered precipitation of the concrete.
Reduce vehicle travel time
The concrete transportation distance is generally within the range of 30km in diameter. The route and the traffic conditions of vehicles shall be planned before departure to minimize the time of vehicles on the road.
Reduce losses and unload first
In case of failure to unload for a long time due to human factors or irresistible factors, the concrete in the tank shall be checked at any time. Once it is found that the concrete begins to set. Unloading shall be carried out immediately after reporting to the person in charge to prevent the whole tank from being scrapped.
2、 The automatic mixer needs to be cleaned at any time, which is troublesome but must be done
1. Flushing at any time during operation
After each unloading, the tank mouth, blade, feed port, tank body and corners shall be washed with the water gun provided by the mixer truck to prevent the concrete from accumulating after solidification and being difficult to clean.
2. Clean the mixer truck after receiving
After the daily transportation task is completed, add more than 1 cubic meter of clean water into the tank and quickly rotate the tank for cleaning. Companies with conditions can also add stones into the tank, and the effect will be better.
1. Control the air pressure and fasten the connector
How much air pressure should be injected into the tank? This is already set at the time of delivery. It does not need to be adjusted by yourself. If it is necessary to adjust under special circumstances, it is suggested that the pressure should be controlled at about 3.5Mpa. If the pressure is too high, it is easy to burst the pipe. In addition, in the new vehicle and daily use, the pipeline interface shall be fastened at any time to prevent falling off.
2. Water adding process of concrete mixer
The arrangement of the water adding place of each concrete mixer truck is similar. Generally, the water tank is vented - filled with water - the water adding valve is closed; When not in use, put the position of the shift lever in the middle.
3. Drain the residual water in winter
After the vehicle is collected every day in winter, the water in the water tank and the water pipe shall be drained, and the compressed air shall be injected into the water pipe to blow out the residual water in each pipeline to prevent the pipeline from freezing and cracking due to icing.
The longer the mixer truck is used, the heavier it is. The reason is that the content explained above. The two major aspects contain several small aspects of relevant information. I hope you can help me. Please come to our website for more attention http://www.jfhntjbj.com Consult.
