<p>A turbo-machine for automatic balancing of fluid-dynamic thrust forces and having an automatic thrust force balancing system comprising: - a balance piston (5) around a discharge end of a rotating shaft (3); - a balance chamber (7) for receiving a leakage flow and for communicating with a downstream side of the balance piston (5); - a balance flow return line (8) connecting the balance chamber (7) with a suction end (39) for conveying said leakage flow; and - a control valve (25) connected to the balance flow return line (8) for regulating the leakage flow rate, wherein the control valve (25) is connected to a temperature controller (26) for regulating the opening of the valve (25); and - the temperature controller (26) is connected to, and receives control signals from, at least one temperature sensor (21, 22) sensing and forwarding the operating temperature of a thrust bearing (9) in the turbo-machine.</p> |
