Fluid coupling type TP

The type TP fill-controlled fluid couplings are predominantly used in drives for shredding machines. The filling level of the coupling can be controlled. This allows load-free motor run-up and controlling of the torque. Thanks to the hydrodynamic principle, the fluid coupling dampens torsional vibration and torque shocks. This protects your drive and increases the productivity of your system.

The thermal capacity of the fluid coupling type TP is very high due to the active cooling circuit. A smoother start up and acceleration over a longer period of the driven machine are therefore possible.

This fluid coupling is also available with two axially arranged working circuits (type DTP). The parallel acting circuits double the power transmission.

For type TPW, the operating medium is water. This coupling is especially suitable for use in potentially explosive atmospheres.

Technical information

Operating principle

 
Operating principle of the hydrodynamic power transmission

Hydrodynamic couplings transmit mech­anical power from the motor to the driven machine via a flow of fluid. This occurs by means of two bladed wheels positioned face to face. The primary wheel (red) is connected with the motor and acts like a rotary pump, the sec­ond­ary wheel (blue) is connected to the driven machine and acts like a turbine. Power transmission is pro­por­tional to the fill level in the working circuit. As a result of the mechanical separation of the drive and driven sides, the hydro­dynamic couplings transfer the power wear-free and dampen the torsional vibration and torque shocks in the drive chain at the same time.

Fill-controlled couplings

Cross-section, fluid coupling type DTP

With fill-controlled couplings, a control device continuously changes the transmission behaviour. This is carried out by changing the filling level and is made possible by controlling the flow of the operating fluid supply and draining using valves.

Fill-controlled couplings have an external fluid circuit that is also used for cooling. This is why these couplings have a very high thermal capacity that makes longer start up procedures with high loads possible. This increases the productivity and reliability of your system.

When starting, fill-controlled couplings are completely empty thus enabling a load-free motor run-up. This relieves and protects the motor and electric network.
