HYDRAULIC MECHATRONIC SYSTEM USED FRO DRIVING A PISTON PUMP USED IN MEDICAL RESEARCH AND DIAGNOSIS

摘要

The invention relates to a hydraulic mechatronic system used for driving a piston pump employed in medical research and diagnosis. According to the invention, the hydraulic mechatronic system consists of a pumping unit composed of an electric pump (1), a safety valve (2), a basin (5), a device (3) for distribution and regulation such as servo-valve or proportional hydraulic apparatus, a driving piston slide valve subassembly (4), to which a pumping piston (7) and an electronic control block (6) are rigidly attached, the subassembly (4) being provided with a position transducer (8) for the precise control of the stroke, hence of the fluid flow rate, by the pumping piston (7), the frequency of movement of the piston (7) being established by an electronic control block (6) and by the servo-valve or the distribution device (3), such as a proportional hydraulic apparatus.
