HYDRAULIC RE-CIRCULATING UNITS
Hydraulic re-circulating units will extend the life of your system. Reducing wear on components. Downtime will be minimal. These units are fitted offline from the main system. Less production loss. The main system as oil can be upgraded offline.
Hydraulics is the study of fluids whether in motion or at rest. Hydrodynamics is the study of fluids in motion, and hydrostaticsconsiders the properties of fluids in static equilibrium (motionless). Concepts from these fields will be used as necessary to explain the operation of hydraulic devices. A water turbine or wheel operates with a large change in the kinetic energy of water; they are hydrodynamic devices.
Specifically, the use of hydraulics (or pressure hydraulics) for power transmission will be considered here. Power transmission is the result of the force of a confined liquid. The confined liquid merely transmits the force generated by the power supply; the flow contributes to the other component of work, i.e., displacement. The amount of work accomplished depends on the overall force and the overall distance to which it is applied. The power supply may be an electric motor, gasoline engine, or hand power. Although the liquid must flow to cause motion, its velocity is usually sufficiently low so as to have only a small kinetic energy component relative to the overall work accomplished (making the hydrodynamic component a trivial consideration). Some common systems that use hydraulics are hand-operated Hydraulic jacks and presses, power steering and brakes on many vehicles, backhoes, and hitch controls of agricultural tractors.
Hydraulic systems offer many advantages, including a high level of flexibility due to their compact size per given level of power, the use of small forces to control large forces, their relatively simple and economical design and operation, and self-lubricating components. Energy is easily transferred by fluid under pressure instead of cumbersome systems of gears and chains or pulleys and belts. Vibration is usually minimal in hydraulic systems.
Safe operation of Hydraulic systems is important as the high pressure involved is potentially dangerous. A failure of the system such as the accidental release of the system’s oil may lead to catastrophe, such as when loaded booms or weights fall suddenly.
