Fluid Coupling and Smooth Power Transmission during Starting and Stopping
A fluid coupling is designed to facilitate smooth power transmission during the starting and stopping phases of machinery and equipment. It achieves this by utilizing the principle of hydrodynamic torque transmission through a fluid medium.
Starting Phase: When power is initially supplied to the input shaft of the fluid coupling, the impeller (also known as the pump) begins to rotate, imparting energy to the fluid inside the coupling. As the fluid gains kinetic energy, it starts moving outward towards the turbine (also called the driven element) due to centrifugal force.
The kinetic energy of the moving fluid causes the turbine to start rotating, transmitting torque to the output shaft. During this starting phase, there is a slight time lag, known as the “slip,” between the impeller and the turbine. However, as the fluid coupling reaches its operational speed, the slip reduces, and the turbine matches the speed of the impeller, resulting in smooth power transmission from the input to the output shaft.
The fluid coupling’s ability to control the slip ensures a gradual and controlled acceleration of the driven equipment, minimizing stress on the drivetrain components and preventing sudden shock loads.
Stopping Phase: When power to the input shaft is reduced or cut off, the impeller slows down, and the kinetic energy in the fluid decreases. As a result, the fluid moves away from the turbine towards the center of the coupling, reducing the torque transmission between the input and output shafts.
This characteristic of the fluid coupling aids in smoothly decelerating the connected equipment, preventing sudden jolts or jerks during the stopping process. The ability to control the slip during deceleration ensures that the driven machinery comes to a gradual and controlled stop, enhancing safety and protecting the equipment from damage.
The combination of hydrodynamic torque transmission and the ability to control the slip makes fluid couplings ideal for applications where smooth power transmission during starting and stopping is essential. Industries such as mining, construction, metal processing, marine propulsion, and power generation benefit from the reliable and efficient performance of fluid couplings in various machinery and equipment.
Fluid Couplings in Hydraulic Drive Systems
Yes, fluid couplings can be used in hydraulic drive systems to transmit power and control the speed of driven components. In hydraulic drive systems, fluid couplings act as a torque converter, providing a smooth and gradual transfer of power between the input and output shafts.
The basic principle of a fluid coupling remains the same whether it is used in a mechanical drive system or a hydraulic drive system. The fluid coupling consists of an input impeller connected to the prime mover (such as an electric motor or an engine) and an output runner connected to the driven component.
When the prime mover is activated, it drives the input impeller, creating a flow of hydraulic fluid within the coupling. This fluid flow creates a hydrodynamic torque that is transferred to the output runner, driving the connected component. The fluid coupling allows for a controlled slip between the input and output, allowing the driven component to start smoothly and gradually reach its desired speed.
In hydraulic drive systems, fluid couplings offer several advantages:
- Smooth Torque Transmission: Fluid couplings provide smooth torque transmission, reducing shocks and vibrations in the system.
- Overload Protection: Fluid couplings can protect the drive system from overloads by allowing some slip in the event of sudden changes in load or jamming of the driven component.
- Speed Control: By controlling the flow of hydraulic fluid, the speed of the driven component can be precisely regulated.
- Energy Efficiency: Fluid couplings can help improve energy efficiency by reducing mechanical losses and optimizing power transmission.
Hydraulic drive systems with fluid couplings are commonly used in various industrial applications, including conveyor systems, mining equipment, marine propulsion, and more. They offer reliable and efficient power transmission while protecting the machinery from excessive loads and shocks.
It’s essential to consider the specific requirements of the hydraulic drive system and the characteristics of the fluid coupling to ensure optimal performance and efficiency in the application.

- Construction: Construction machinery like cranes, loaders, and piling rigs use fluid couplings for efficient power transmission and reduced shock loads.
- Marine: Fluid couplings are employed in marine propulsion systems to optimize engine performance and protect against sudden load changes.
- Steel and Metal Processing: Industries dealing with metal processing use fluid couplings in rolling mills, coilers, and metal forming machines for soft start and overload protection.
- Pulp and Paper: Pulp and paper mills utilize fluid couplings in various equipment, such as chippers, conveyors, and pumps, for smooth power transmission.
- Automotive: In automotive applications, fluid couplings can be found in torque converters, which provide smooth torque transmission in automatic transmissions.
- Energy and Power Generation: Fluid couplings are used in power plants for applications like fans, pumps, and turbines to control power transmission and reduce mechanical stress during startup.
- Wastewater Treatment: Fluid couplings are used in wastewater treatment plants for applications like aerators and pumps, ensuring efficient power transmission and equipment protection.
