In the construction industry, the small concrete mixer is often used as a transport vehicle. In terms of normal maintenance, the automatic loading mixer truck should pay attention to cleaning and maintenance. Some careless people may ignore these details, and the results will be very satisfactory. But if we just pay attention to these, it will greatly extend the life of the automatic feeding mixer.
The things you have to do every day are as follows:
1. Flush the feed port with water before each loading to keep the feeding port moist during loading;
2. At the same time of loading, fill the water tank with water;
3. After loading, wash the inlet to clean the residual concrete near the inlet;
Automatic feeding mixer
4. After unloading at the construction site, wash the discharge tank, and then add 30-40 l of cleaning water into the concrete storage tank; keep the concrete storage tank in forward and slow rotation when the vehicle returns;
5. Remember to discharge the sewage in the concrete tank before the next loading;
6. At the end of each day, the concrete storage tank and the surrounding area of the material inlet and outlet shall be thoroughly cleaned. The cleaning points of the automatic feeding mixer truck shall ensure that there is no cement and concrete caking.
Because the concrete will condense into a hard block in a short time, and has a certain degree of corrosivity to steel and paint, so it is necessary to carry out daily maintenance to clean the concrete adhered to the concrete storage tank and the inlet and outlet after each use of the concrete tank. It includes: flushing the inlet with water before each loading to keep the inlet wet during loading; filling the water tank with water during loading; flushing the inlet after loading to clean the residual concrete near the inlet; after unloading at the construction site, wash the discharge tank, and then add 30-40l cleaning water into the concrete storage tank; adhere to the principle of filling the water tank with water for cleaning when the vehicle returns The concrete tank is rolling slowly forward.
If these works are not carried out carefully once, they will bring great trouble to the future work. The electrical control system is the nerve center of the automatic feeding mixer and the primary guarantee for the normal operation of the pump truck. The composition of the system is disorderly, and the positioning of its shortcomings is relatively difficult.
