Principle of Concrete Pump

Principle of Concrete Pump

The principle of concrete pump is based on the understanding of the movement and properties of concrete. A concrete pump is a machine that is designed to transfer liquid concrete from a mixing truck to the desired location using a valve system and pressurized flow of the concrete. The process involves using a piston or a screw to push the concrete through a series of pipes until it reaches the destination.

The following are the key principles of a concrete pump:

1. Pressure Principle: A concrete pump works on the principle of pressure. The machine uses a powerful hydraulic system that generates high pressure to move the concrete through the pumping system. The pressure generated by the pump can reach up to 1500 pounds per square inch (psi) which is strong enough to push the dense concrete mixture through long pipelines and to higher elevations.

2. Suction Principle: The suction principle of a concrete pump works on the same concept as a vacuum cleaner. As the pump’s valve system opens, the pressure inside the pipes decreases, creating a suction force that draws the concrete into the system. The suction force is created by the rotation of the pump’s piston or screw that pulls the concrete towards it.

3. Valving Principle: The valve system of the concrete pump allows for efficient and continuous movement of the concrete through the pipes. The concrete is pushed out of the cylinder by the rotation of the piston or screw towards the outlet valve, opening it to let the concrete move through. Once the concrete has passed through the outlet valve, the inlet valve opens and the cylinder is filled with more concrete, which is then pushed towards the outlet valve.

4. Conveying Principle: The conveying principle of a concrete pump involves the transfer of concrete from the mixing truck to the desired location. The concrete is pumped through either a steel or rubber hoses connected to the outlet valve, which can be up to hundreds of meters long. The conveying speed depends on the size and type of the pump and the diameter of the pipeline.

5. Placement Principle: The primary principle of a concrete pump is to efficiently and accurately place the concrete to its desired location. The pump’s valve system and the flexible hoses allow the concrete to be placed even in hard-to-reach areas or on higher levels, which would be inaccessible by other methods of concrete placement.

In conclusion, the principle of a concrete pump is based on the efficient handling of concrete, which involves creating and managing high pressure to move the concrete through the system and utilizing a valve system to facilitate the precise placement of the concrete. A concrete pump is an essential equipment in modern construction, providing a faster, more accurate and cost-effective way of placing concrete.
