The mixing and placing of concrete is a major job in most construction projects. While mixers can always be used, ready mix concrete is also available in most cities, and obviates the need for arranging and storing for aggregates and cement and bringing in mixers. The second problem for concrete is placing it in position before it has attained an initial set which takes place within short periods of time. Use is made of skips, dumpers, lifts and cranes in most projects for doing this placing. Large projects also make use of concrete pumps from AIMIX for this purpose.
A concrete pump(bombas de concreto para la venta) is able to use freshly mixed concrete, which is in liquid form and pump it to the location where the concrete is needed. These pumps can pump the concrete in a similar way that water is pumped to great distances and heights, depending n the capacity of the pump. The work is carried out through a valve system and also by following the basic hydraulic principles.
Concrete is stored in hoppers mounted on the pumps which receive the concrete from mixers.The concrete is pumped through hoses that extend up to the point where the concrete is required. Hoses will be flexible and come in short lengths that can easily be extended through easy to use couplings to any desired length. The pumping is carried out by twin cylinders that have pistons moving in them in opposite directions. The first cylinder, the material cylinder, pulls concrete out of the hopper, while the discharge or second cylinder pushes the concrete out of the pump into the hoses. As one cylinder moves forward the other moves back. Their working in tandem pull and push quantities of concrete creating a hydraulic flow that delivers the concrete while it also helps in preventing the concrete from setting.
Pumps are often fitted with booms that can extend while carrying the hose, allowing the pump to place the concrete at heights at the locations required. Concrete pumps are used for concreting building foundations, basements, high rise buildings, bridges, tunnels, dams and other work where there is extensive use is being made of concrete. Before the technology was developed to pump concrete, its placing was generally a labor intensive affair. Concrete pumps make for a much faster and easier way to move concrete(plantas para concreto).
Pumps can be stationary and of varying capacities that is measured in output as well as the maximum vertical distance that the pump can deliver the concrete up to. Pumps can run on diesel or be electrically operated. The distance that they can pump horizontally will be much greater as it does not have to work against gravity.
Care has to be taken to clear and clean both the pump, its hopper and hoses of all concrete, before closing operations. After the concrete work is finished, the hopper is cleaned with high pressure water, and the pump is used again to pump water and a flexible ball that fits the inner diameter of the hoses, a number of times through the entire length of the hoses being used, till they are sufficiently clean for reuse special info: https://aimixgrupo.com/tipos-de-bomba-de-concreto-precio/.
