technical features:
hydrodynamic couplings are distinguished by:
Hydrodynamic couplings belong to the group of hydrodynamic power transmission devices.
• power transmission free of wear
• steady shock free start up in loaded or unloaded state
• slight backlash on the electrical power supply due to fast abating of the start up current and low start up current
• load compensation on multi motor drives
• efficient discoupling of vibration systems
• damping of shocks, vibration and load changes
• protection against thermical overload by the installed fusible plug or by a mechanical or electronical switch off device
The power transmission is done by mass forces of the operation liquid according to the „Fröttinger Prinzip“. The impeller pump absorbs the mechanical power of the drive and increases the energy
of the circulating operating liquid. The turbine wheel takes energy away from the operating liquid and outputs mechanical power.
There is not any fixed connection between both wheels. Slight power losses, caused by the for the power transmission necessary
slippage, will be transformed to heat.
The permissible ambient temperature range of the hydrodynamic coupling in standard design is between - 25 °C and + 40 °C
(other values on request).
