PRODUCT DESCRIPTION
 - A fluid coupling is a hydrodynamic device used to transmit power between two rotating shafts. It consists of an input (driving) shaft connected to a pump, an output (driven) shaft connected to a turbine, and a working fluid contained within the coupling.

 - When the input shaft rotates, it drives the pump, which imparts kinetic energy to the working fluid. The fluid is then directed towards the turbine, which is connected to the output shaft. As the fluid flows through the turbine, it transfers its energy to the turbine and causes it to rotate, thereby transmitting power to the output shaft.

 - The key characteristic of a fluid coupling is its ability to provide a smooth start-up and gradual acceleration. As the input shaft starts rotating, the working fluid gradually builds up speed and transfers the torque to the output shaft. This feature helps to reduce shock and stress on the connected machinery, protecting them from sudden jolts or overloads.

BENEFITS
 : Smooth Start-up and Acceleration
 - Fluid couplings provide a gradual start-up and acceleration of connected machinery. As the fluid coupling allows for a controlled build-up of torque, it minimizes shock and stress on the equipment during start-up, reducing wear and tear and extending the operational life of the machinery.

 : Torque Amplification and Load Handling
 - Fluid couplings offer torque multiplication, allowing for higher torque output than the input torque. This feature helps in overcoming inertia and handling heavy loads, providing additional power during start-up or in situations where extra torque is required.

 : Overload Protection
 - Fluid couplings act as a protective device for connected machinery. In case of sudden load increases or overloads, the fluid coupling can slip, allowing the working fluid to bypass the turbine. This helps to limit the torque transmitted to the output shaft, preventing damage to the equipment and providing overload protection.

 : Vibration and Shock Dampening
 - Fluid couplings dampen vibrations and shocks caused by load variations or disturbances in the system. The working fluid absorbs and dissipates these vibrations, reducing stress on the connected equipment and ensuring smoother operation.

FUNCTION
 : Torque Transmission
 - The primary function of a fluid coupling is to transmit torque from the input (driving) shaft to the output (driven) shaft. When the input shaft rotates, it drives the pump within the fluid coupling, which imparts kinetic energy to the working fluid. The fluid then transfers this energy to the turbine connected to the output shaft, causing it to rotate and transmit torque.

 : Smooth Start-up and Acceleration
 - Fluid couplings allow for a smooth start-up and gradual acceleration of connected machinery. As the fluid coupling operates, it gradually builds up torque transmission, enabling a controlled and gentle start without sudden jolts or shocks. This feature helps protect the machinery from excessive wear and reduces stress on the connected components.

 : Load Handling and Torque Amplification
 - Fluid couplings can handle and transmit higher torques than the input torque. This torque multiplication capability allows them to handle heavy loads and overcome initial resistance during start-up. The fluid coupling can amplify the torque output to provide additional power when required.

 : Overload Protection
 - Fluid couplings act as a protective mechanism for connected machinery. In the event of sudden load increases or overloads, the fluid coupling can slip, allowing the working fluid to bypass the turbine. This slip operation limits the torque transmitted to the output shaft, protecting the machinery from damage caused by excessive loads or unexpected shocks.

CAUTION
Fluid couplings can generate heat during operation, especially under heavy loads or prolonged use. It is important to ensure proper cooling and ventilation to prevent excessive heat buildup, which can affect the performance and longevity of the coupling.
