The working environment of the automatic self loading concrete mixer truck is relatively bad, and the user does not pay attention to daily maintenance, which has caused some unnecessary failures and economic losses. I hope that the daily use of the majority of automatic self loading concrete mixer truck users will be introduced through the editor below. And maintenance play some role.
1. The body of the automatic self loading concrete mixer truck should be maintained first. Every time the concrete is transported and into the cleaning tank, it is necessary to know that concrete is the easiest to bond with steel.
Second, the uniformity of the discharge is one of the important indicators of the automatic self loading concrete mixer truck tank, which directly affects the construction quality. When conveying concrete, the speed of the mixing drum should be controlled at 2~5r/min. When the transportation interval is long and the concrete slumping may be large, the mixing drum should be quickly moved 5-10 times before discharging, so that the inside
Concrete can be fully mixed, so that the uniformity of the discharge will be greatly improved. If coagulation loses water on the way, water should be added to the construction site to adjust, and the mixing should be enriched. Although this environment should only be controlled, this will make the quality of the concrete not guaranteed. Some users do not pay attention to controlling the speed during transportation, too fast will increase fuel consumption, and too small will cause concrete segregation. Therefore, the speed of the mixing drum should be controlled strictly according to the requirements to improve the quality of concrete transportation.
Third, the maximum limit of concrete cannot be higher than the maximum volume of the tank, because the density of concrete is different because of the difference in the strength of the concrete. High-strength concrete generally has a higher density, and the same volume is unlucky for the car. The capacity, quality and slump of the conveyed concrete should meet the requirements in the vehicle manual, and the lubricant should be filled in real time.
4. For the self loading concrete mixer truck parked in the open, the mixing drum should be rotated in the discharge direction before loading, and the accumulated water in the cement tank should be released to ensure the quality of the concrete.
