    DESCRIPTION & OPERATING CONDITIONS DESCRIPTION The TRANSFLUID coupling (K series) is a constant filling type The slip is essential to the functioning of the coupling: there could comprising three main elements: not be torque transmission without slip! The formula for slip, from 1 Driving impeller (pump) mounted on the input shaft.

  • Page 5: Advantages

    FLUID COUPLING FITTED ON ELECTRIC MOTORS TRANSFLUID COUPLING FITTED ON ELECTRIC MOTORS Any drive system using a Transfluid fluid coupling has the advantage of the motor starting without load. Figure 2 compares Three phase synchronous squirrel cage motors are able to supply the current demands of an electric motor when the load is directly maximum torque only near 100% synchronous speed.
  • Page 6 FLUID COUPLING WITH DELAYED-FILL CHAMBER ADVANTAGES TRANSFLUID FLUID COUPLINGS WITH A DELAYED FILL Fluid couplings with single or double delay fill chamber provide CHAMBER very smooth start-ups with low start-up torque transmission, and this makes them excellent for applications with high inertia loads With the standard circuit in a maximum oil fill condition, fluid and for use on belt conveyors.

    RECOMMENDED OIL AND QUANTITY SAFETY DEVICES OIL FILL SAFETY DEVICES Transfluid fluid couplings are generally delivered without oil. FUSIBLE PLUG Therefore, it is necessary to follow the filling procedures listed below : In case of a load lock-up or high slip in the fluid coupling the oil 1 - For a fluid coupling monted on a horizontal shaft, turn the temperature in the coupling will reach very high levels.

  • Page 28 SAFETY DEVICES OPERATION OVERLOAD CONTROLLER Fig. 7 1490 When load torque increases, slip also increases and output speed consequently decreases. The said speed variation can be measured by means of a sensor sending a pulse train to the speed controller. If the rotating speed goes lower than the set threshold (see diagram) on the controller, a signal is given through the activation of the controller’s relays.
  • Page 29 FIG. SAFETY DEVICES OPERATION Fig. 9 FIG. INFRARED TEMPERATURE CONTROLLER This is a non contacting system to check fluid coupling temperature. It is reliable and easy-mounting. It has 2 adjustable thresholds with a logical alarm on the former, and a relay alarm on the latter. The proximity sensor must be positioned near the fluid coupling outer impeller or cover, according to one of the layouts shown in Fig.
