Concrete Mixer And Pump

Core technology of pumping accuracy innovation

The pumping accuracy innovation of the new generation of concrete pumps is due to the deep integration of advanced sensors and intelligent control systems.
High-precision pressure sensors and flow sensors are installed in key parts of the concrete delivery with pump, such as hydraulic pipelines, pumping cylinders, and conveying pipeline connections. These sensors are like the "nerve endings" of the pump truck, which can capture subtle changes in pressure and flow during the pumping process in real time with a response speed of milliseconds.

For example, the measurement accuracy of high-precision pressure sensors can reach ±0.1 MPa, and the error range of flow sensors is controlled within ±1%, ensuring that the collected data is accurate and reliable.​

The intelligent control system is the "smart brain" of the concrete pump truck. It uses complex algorithm models to analyze and process the data collected by the sensors.

When the concrete pumping equipment pumps concrete upward in the construction of high-rise buildings, as the height continues to increase, the gravity and pipeline friction on the concrete also increase accordingly. At this time, the intelligent control system will automatically adjust the pressure output of the hydraulic system according to the preset parameters and real-time monitored data, and accurately control the movement frequency and stroke of the pumping piston, thereby realizing dynamic adjustment of the pumping pressure. At the same time, the system can also optimize the pumping flow rate according to the slump of concrete, aggregate particle size and other characteristics, ensure that the concrete is delivered to the designated location at a stable and uniform speed, and avoid problems such as concrete segregation and pipe blockage caused by pressure and flow fluctuations.

Excellent performance in different scenarios​

In the field of high-rise building construction, the improvement of the pumping accuracy of mobile concrete pumps plays a vital role.
Take the construction of a super-high-rise skyscraper as an example. The total height of the building is more than 300 meters. During the pouring of the core tube concrete, it is difficult for traditional pump trucks to accurately control the pumping pressure and flow rate. There are often cases where the concrete delivery is interrupted due to insufficient pressure, or the pipe bursts due to excessive pressure. The new generation of concrete pump trucks, with advanced sensors and control systems, can automatically adjust the pumping pressure between 15 and 35 MPa in each pumping cycle according to the actual delivery height and distance of the concrete. At the same time, through the precise control of the flow rate, the concrete pouring speed is kept in a stable range of 30 to 50 cubic meters per hour, ensuring the continuity and density of the core tube concrete pouring, and effectively improving the overall quality of the building structure. Compared with traditional pump trucks, the material waste rate is reduced by about 15%, and the construction efficiency is increased by more than 20%. ​

In linear projects such as bridge construction, towable concrete pumps also show strong advantages.
The pouring of the box girder of the bridge requires extremely high uniformity and density of the concrete. Any slight deviation may affect the bearing capacity and service life of the bridge. The new generation of concrete pump trucks can accurately adjust the pumping parameters according to the structural characteristics and pouring requirements of different parts of the bridge. When pouring the web of the box girder, the system automatically reduces the pumping speed to ensure that the concrete can fully fill the gap between the steel bars; when pouring the top plate, the flow rate is appropriately increased to ensure that the concrete surface is flat and smooth. In the construction of a cross-sea bridge, a new generation of concrete pump trucks were used for box girder pouring, and the pouring qualification rate of concrete increased from the original 92% to 98%, effectively ensuring the construction quality and progress of the bridge.

The far-reaching impact of the innovation

The improvement of pumping accuracy not only significantly improves the pouring quality of concrete, but also has a positive impact on cost control and construction safety. In terms of material cost, precise pumping control reduces the waste of concrete and reduces the direct cost of engineering construction. According to statistics, in large-scale construction projects, the use of a new generation of trailer mounted concrete pumps can save hundreds of thousands of yuan in concrete material costs each year. In terms of construction safety, stable pumping pressure and flow avoid safety accidents such as pipeline bursting caused by sudden pressure changes. At the same time, the fault warning function of the intelligent control system can detect potential equipment problems in advance and take timely measures for maintenance, effectively ensuring the personal safety of construction personnel and the normal operation of equipment. ​

In addition, this technological innovation has also promoted the progress of construction technology. In the past, due to the limitations of pump truck pumping accuracy, some complex architectural shapes and structural designs were difficult to achieve. Today, high-precision ready mix concrete pump trucks provide architects and engineers with more creative space and promote the innovative development of the construction industry. With the continuous maturity and popularization of technology, small portable concrete pumps are expected to achieve greater breakthroughs in pumping accuracy in the future, bringing more surprises and changes to the construction industry.
