A concrete pump is a mechanical machine that utilizes pressure to continuously transport concrete along a pipeline. It is mainly composed of a hydraulic pump and a delivery pipe. There are different types of concrete pumps, including piston pumps, squeeze pumps, and hydraulic diaphragm pumps. The hydraulic pump is typically mounted on a truck chassis and equipped with extendable or articulated placing booms to form a pump truck. This machinery is designed to save time in transporting and pouring concrete, making it particularly suitable for projects requiring large volumes of concrete pouring, as well as high-quality construction with large volumes and thick foundations.
The working principle of a concrete pump truck is to utilize pressure to continuously transport concrete along a pipeline. It consists of five components: boom, pump, hydraulic, support, and electrical control. The power from the engine is transmitted to the hydraulic pump group or rear axle through a power split gearbox. The hydraulic pump drives the piston to work and pumps concrete with the help of the placing booms and delivery pipes on the pump truck, transporting the concrete to a certain height and distance.
The operation and control of a concrete pump truck are crucial. The control methods of its electrical control system include mechanical, hydraulic, electromechanical electrical control, programmable controller, and logic circuit control to ensure safety and efficiency. During use, it is important to follow safety operating procedures, avoid using it under high stress, reduce resonance effects, control the load intensity, and prevent premature fatigue cracks to ensure the long-term use and safety of the pump truck.
The structure and principle of the pump truck involve the coordinated work of multiple systems and components, including chassis, boom system, turret, pumping system, hydraulic system and electrical system, etc. Each part has its specific function and role, which together ensures the efficient transportation of concrete and the accuracy of material distribution.
