What is the working principle of a concrete pump? 2026-10-10

A concrete pump uses hydraulic power to drive the main oil cylinder, which pushes the pistons in the delivery cylinders to reciprocate alternately. Together with the switching of the S pipe valve (swing valve), it completes the suction and discharge cycle. When one piston retreats, concrete in the hopper is drawn into the delivery cylinder; at the same time the other piston moves forward and presses the concrete in its cylinder into the delivery pipeline, continuously conveying the concrete along the pipe to the pouring point. The agitator in the hopper keeps stirring the material to prevent segregation and caking, ensuring smooth feeding. The whole hydraulic system controls pressure and flow, and the pumping speed can be adjusted to the working conditions; the inner wall of the pipeline withstands the high pressure that pushes the aggregate. Different models work on the same principle; the differences lie in hydraulic pressure and cylinder specification, which determine the conveying distance and the applicable aggregate. Widely used in building construction, it can convey ordinary concrete and fine aggregate mortar and, with different pipelines, handle vertical high-rise and long-distance horizontal conveying. It is the core equipment for continuous concrete placing.

What are the advantages of a mobile concrete pump over a fixed pump? 2026-10-10

The biggest core advantage of the mobile concrete pump is its self-propelled traveling structure, which allows flexible movement and relocation at any time, completely solving the problem of the cumbersome and time-consuming relocation of traditional fixed pumps. The unit features an integrated design, with the pump body, power system and traveling chassis assembled as one, requiring no disassembly or reassembly. Short-distance movement within a site and relocation between sites are both very convenient, greatly saving construction preparation time. The power system is stable and strong, with sufficient pumping pressure, suitable for pumping ordinary concrete and fine aggregate concrete; the conveying height and distance meet the needs of multi-storey buildings and small and medium-sized infrastructure. The equipment is wear-resistant and robust, with good hydraulic cooling performance, allowing long continuous operation with stable running and low risk of pipe blockage. It is widely used in projects requiring frequent relocation, such as scattered house building, road repair, courtyard renovation, small plant construction and multi-area sectional pouring, with maximum mobility and far greater construction flexibility than ordinary fixed pumps.

What is the main use of the secondary-structure concrete pump? 2026-10-10

The secondary-structure concrete pump is special equipment customized for secondary construction work. It is mainly used for pouring secondary-structure concrete such as structural columns, ring beams, lintels and infill walls, and specifically solves the problems of manual pouring: low efficiency, poor compaction and incomplete filling. The machine is compact, light and highly maneuverable, and can easily enter and leave building floors, narrow corridors and confined construction spaces without site restrictions. It adopts a low-pressure fine aggregate pumping design suitable for fine aggregate concrete and mortar, delivering fine and uniform output, with dense pouring free of hollows, honeycombing and pitted surfaces, and a high rate of qualified construction quality. The equipment is simple to operate, with low energy consumption, low noise and high speed; compared with manual pouring, efficiency is improved several times over, greatly saving labor costs. It is widely used for secondary-structure pouring in buildings, indoor structural column construction, floor slab repair and small wall pouring, both indoors and outdoors.

What are the structural advantages and suitable scenarios of the inclined secondary-structure fine aggregate pump? 2026-10-10

The inclined secondary-structure fine aggregate pump adopts a unique inclined body structure and is an upgraded unit dedicated to fine aggregate pouring. Compared with traditional horizontal pumps, it feeds more smoothly, is less prone to material accumulation and pipe blockage, and is fully suited to fine aggregate mortar pumping. The inclined body shortens the feeding stroke, giving faster feeding and uniform, stable output. It is specially adapted to pumping fine materials such as fine aggregate concrete, cement mortar and floor heating backfill slurry, effectively avoiding material stratification and segregation. The lightweight design makes it easy to move and carry, allowing free access to building floors, basements and confined construction areas. It is simple to operate, with low energy consumption and low noise, making it suitable for precise indoor work. It is mainly used for building secondary structural columns, ring beam pouring, floor heating backfill, roof leveling, indoor floor repair and wall plastering feeding, and is the preferred equipment for indoor fine aggregate pouring and small-scale supplementary material work.
