Surface Treatments Machine – Retexturing Lancashire County
The machines shown
in this paper embrace the latest available computer, hydrological and aeronautical technology to produce the most technically advanced devices of their type available in the world. Very highly engineered pumps and plumbing systems are utilized to ensure constant flow and variable pressure. Aeronautical technology has been used in producing sufficient airflow’s to enable the water and surface debris to be recovered at the point of treatment. The entire system is computer managed and hydrostatically driven, thus providing accurate control of working speed (0-10 KM/Hour) and water pressure. These machines treat pavement surfaces from 2.5 – 3.9 meters width depending on the particular unit concerned. The finished surface is uniform in appearance. Rotating jets, hydraulically driven, impart directed and controlled water at pressures between 100 and 2000 bar and through a variety of jet nozzle types depending upon the activity. Water flow rates vary from-29 – 140liters per minute, again, depending upon the particular activity to hand. As the ‘water blasting’ system unerringly does it’s job, the highly efficient vacuum system immediately collects the used water and debris, (crucially) at the point of treatment, through primary and secondary recovery systems by way of a powerful vacuum generated by a 900mm fan rated at 90 kW, which produces 30,000m3/h or air volume at 265 per hour. The latest unit being operated in Europe has two ventilators
