Compressesors Doosan Portable Power, essential in big polls

To realise big polls, with depths and remarkable diameters, require high values in pressesure and discharge of air compressesed. To fulfil these requirements, the company Perforaciones Romera, devoted to the sector of the perforación and alumbramiento of groundwaters, has of six units of compressesors of Doosan Portable Power model 25/330.

The company Perforaciones Romera forms part of the group Workshops and Cranes González, is situated in Pulpí (Almería) and has a wide experience avalada by more than 50 years in the sector of the perforación to national level.

Compressors Doosan Portable Power employed in tasks of perforación.

At present Perforaciones Romera is considered one of the first companies of Spain regarding number of teams of perforación and compressors, consolidating firmly in the market.

Perforaciones Romera, in addition to his park of machinery, possesses personnel highly qualified: specialists in hydraulic, mechanical, soldadores and professionals that handle the teams. Also it has of a department that gathers a technical team of professionals: geólogo, engineer of mines and engineer of public works, that allow to propose to the customer the most adapted solution in each poll.

“Along the years have gone incorporating in the company the human means and the necessary technology for the utilisation of any system of perforación, and like this can drill in any class of terrain with the greater efficiency and total guarantee of success”, indicates Emilio J. Fernández Carrión, graduate in Geology and member of the company.

“Have three machines of percussion, one of rotation to slime, one of rotopercusión and our machine crashes: a mixed machine, able to work with rotopercusión and reverse circulation, with capacity for big depths to big diameters, as well as compressors Ingersoll Rand, (at present designated Doosan Portable Power, after the absorption of this division by Doosan Infracore Construction Equipment (SAY CE)”, continues saying Emilio J. Fernández Carrión.

Big polls

This rotatory system with air compressed consists in a hammer of percussion that has placed in the inferior extreme of the pipe of perforación (varillaje), which combines the effect percutor with the rotatory action of the respective teams. There are three key appearances for the good operation of this system: first, the compressors have to be of high pressure and big discharge of air; second, a good election of the hammer; and third, that the system work in terrains consolidated, since of the contrary the pozo runs the risk of derrumbarse during the perforación.

Emilio J. Fernández Carrión, of the company Perforaciones Romera.

“Our park of machinery is new, try to incorporate the last advances in perforación, to offer to the customer the best service. The function of the compressors in this type of tasks is vital. We can not allow us that these fail. His mission is the one to be to 100%, from beginning to end of the perforación. Thus we have of six units of compressors of Doosan Portable Power model 25/330”, adds Emilio J. Fernández Carrión.

The majority of the works that realise with the help of these compressors are of big polls, with depths and considerable diameters, as for example for the desaladoras, basins of rivers, supplies for municipalities, pozos of protection catódica, poll of recognition in tunnels. It is usual to work with several compressors in parallel in polls of big depth and big diameters.

“Ours main customers are the administrations or important companies of the construction that act in the international field. The compressors are essential part in the success of our work, and in this the reliability and robustness that provide us the compressors 25/330 of Doosan Portable Power does not admit doubt”, concludes Emilio J. Fernández Carrión.

Maximum provision

The model 25/330 is the elder of the range of compressors of Doosan Portable Power, formed by 24 models, with exits of air that go from the 2 to the 45 m³/min, with pressures of 7 until 25 bar.

Mounted on a truck, the compressors offer a big mobility of a task to another.

The compressor 25/330 possesses a free exit of air of 331 (1170) m³/min (cfm), offers a pressure in normal operation of 25(365) bar (psi), and a maximum pressure of 25,9 (375) bar (psi).

All these compressors have been conceived to contribute a high level of productivity, the maximum durability and a simple maintenance for the user. His design offers an easy access to the components in tasks of maintenance, and the intervals of tuned of all they have been racionalizados to avoid supplementary expenses. The materials and components are of first quality and guarantee the maximum security so much in the performance as in his useful life.

The handle is very practical and intuitive. In the signpost of control can observe the different functions. His modular conception allows to add easily supplementary accessories adapting like this the compressor to the needs of each customer.
