Description

Fluid couplings for large machinery with high torque of inertia VULKAN fluid couplings are based on the Föttinger principle of hydrodynamic couplings. In its simplest version, a fluid coupling comprises a drive wheel connected with the driveshaft (e.g. an electric motor or combustion engine) and a running wheel connected with the driven machine shaft. Fluid coupling operational principle The drive wheel and driven wheel are fitted with radial rotor blades and there is no mechanical connection between them. The coupling is filled with a specific amount of fluid (mineral oil or a mixture of mineral oil and water). The main torque generated by the drive machine is converted into operating fluid hydrokinetic energy through a fluid swirl which circulates between the rotor blades in the drive wheel and in the running wheel. This energy is then reconverted into a mechanical torque and conveyed to the driven machine shaft Versions and accessories VULKAN fluid couplings are available with both constant filling and fluid level controlled couplings to meet the highest requirements. A comprehensive accessory range is also available, including: Melting plugs for different temperature settings Safety overload fuses and current load switches Temperature sensors Brake discs and drums Electric/pneumatic actuators for speed control Heat exchangers Oil circulation pumps Fluid coupling benefits No-load motor start up Limited maximum torque transmission to the motor during start up and therefore overload protection Maximum torque transmission at start can be set to between 80% and 270% of the actuation torque
