ADVANTAGES• Initial Cost Saving - Allow to use simple squirrel cage motor, designed for running

condition, in place of costly slip ring motor designed for starting conditions.

• Improves life of Motor - Smooth & controlled acceleration from stationary to running condition.

• Running Cost Saving – Allows to reduce the speed of fan / pump to control the discharge, instead of using dampers, vanes, valves etc.

• Low maintenance cost - wear-free power transmission through hydrokinetic energy.

• Dampening against Torsional Vibration & Shock Load - Mechanical separation between driving & driven equipments by dampening of torsional vibrations and shock load.

• Easy Operations - Easy governing of scoop tube position by actuator or manually for speed control.

• Self Supported - The rotating mass is covered by self-supported stationary housing which does not load the motor and machine bearings. Also, no hazards of accidents.

• Proper Sealing - Labyrinth seal with oil seal ensures no oil leakage from shaft end.

VARIABLE SPEED - SCOOP OUPLING

Installed - ESC 660 at Adani Power Plant for 500 kW @ 1500 rpm

VARIABLE SPEED - SCOOP OUPLING

WHY SCOOP COUPLING ?

IF WE GET VARIABLE FLOW BY USING DAMPER, VANE CONTROL, CENTRIFUGAL PUMP, etc. THEN FOLLOWING ARE THE LOSSES.

MAXIMUM POWER CONSUPTION. EROSION OF FAN BLADES DUE TO

MAXIMUM SPEED. WASTE OF ENERGY.

ABOVE LOSSES CAN BE AVOIDED BY USING SCOOP COUPLING.


Four Modes : 1. Motor Start-up : Start-up against No Load with the almost empty Coupling. Scoop tube is in

Full-In Position. No Contact between Motor & Machine.

2. Starts of Driven Machine : Started Gradually by filling Oil inside the working circuit with the change of Scoop tube position. Result of increasing Oil qty. inside working circuit, output speed and Torque Transmission is increase.

3. Operation at Max. Driven Speed : This mode is achieved by Pulling Scoop Tube totally outside. Fluid inside the coupling is max. as a result it will give max. output speed. Slip is Min. and Efficiency is High.

4. Operation at Part Load & Speed : Any speed between Max. & Min. is obtained by changing the Scoop tube position accordingly. Automation of this function is possible to obtain desired output speed.
