Fluid Couplings | Applications

Why do engineers need Fluid couplings?

The answer is simple. A fluid coupling is a device which allows a controlled amount of slip between input & output, between the drive and driven machine, with no mechanical contact.

Because of this, fluid couplings offer the engineer real advantages, in many different kinds of power transmission.

These advantages include control starting, smooth acceleration, overload protection, energy saving, stepless speed regulation, virtually frictionless clutching, starting from zero motor load and thus reduction in motor size, torsional isolation (important for example between diesel engine and its load) and long-term reliability of a drive which has no mechanical contact between the power-transmitting elements.

Fluid coupling also known as hydraulic coupling is a hydrodynamic device which is used to transfer rotational power from one shaft to another by the use of transmission fluid.

It is used in automotive transmission system, marine propulsion system and in industries for power transmission. It is used as an alternative for the mechanical clutch.

What are the types of fluid couplings?

In practice there are two types of fluid couplings; Constant Filling, where the oil filling is fixed and variable filling also known as variable speed where the quantity of oil in the working circuit can be varied whilst running to give control over the amount of slip between the impeller and runner and so give speed regulation.

The variable filling fluid coupling also gives a means of declutching a machine from its drive and are used extensively in conveyor drives to control accurately the torque applied during acceleration and give easy load balancing using external controls.

Where are they use fluid couplings?

In general fluid couplings are used in Belt conveyors, Extruders, Centrifuges, Bucket elevators, Ball mills, Crushers, Mixers, Slurry pumps, Compressors, Industrial fans, Feeders, Diesel locomotives, Wagon tipplers, Boiler feed pumps, Reciprocating pumps, Process Pumps, Dryers etc.
