WebModern hydraulic pumps (axial-piston, radial, vane, etc) are designed with internal leakage passages for cooling. Somewhere between 2-6% of total flow is "leaked" or intentionally siphoned away from the flow outlet for cooling of the pump's sliding surfaces. The flow rate through these passages is obviously dependent on viscosity. WebHydraulic systems are based on the principles of fluid dynamics; this important branch of science deals with the movement of fluids. An understanding of the key principles …
