Looking at the energy needs of today's world, we immediately understand that, through improved efficiency, we can save energy without increasing consumption, and hence without increasing costs. Drilling Equipment is a typical market sector which requires better machines to give faster drilling with, wherever possible, greater economy. Other vitally important aspects of these machines are the need for them to be inherently industrial safe and environmentally friendly, or green, as it is now known. Now the hydraulics in the head can take advantage of the increased performance of SAI variable displacement radial piston motors. By installing SAI high torque, high speed motors with continuous displacement adjustment, the drilling head performance can be increased substantially.
Advantages can be achieved due to the extremely high volumetric and mechanical efficiencies, lower noise emissions and reduced vibration of the driving unit. These advantages result in higher precision and an extremely wide operational range for the Machines, as well as much improved operator comfort. Coupled to all of this is the main aim of the exercise, that being, the reduction in energy losses (by the elimination of unwanted heat and noise generation) and the resultant reduction in fuel consumption.
To summarise all of the above, Drilling Machines incorporating SAI Variable Displacement Motors run “Leaner and Greener” giving them a clear "Licence To Professional drill"!
