Fluidomat - Model Type Scoop -Variable Speed Scoop Coupling
FLUIDOMAT -SC is a variable speed fluid coupling providing stepless speed variation in a wide range when connected to fixed speed electric motor. The speed variation is obtained by varying the oil filling in coupling through a sliding scoop tube when in operation.
It offers flexibility in controls as it can respond to various electric, pneumatic or hydraulic signals and it is compatible with all types of controllers like pneumatic, hydraulic, electronic, electrical or manual. Beside it offers all the advantages of constant speed fluid coupling like load limiting, absorption of shock loads, torsional loads and vibrations, smooth acceleration etc. Its built-in safety arrangements make it fool-proof during operation.
Fluidomat SC offers advantages like no load starting of motor, controlled starting torque for machine acceleration, continuous declutching, stepless speed variation and synchronizing of motors in multidrive units, load limiting in a very wide range for safety of motors and machine.
Due to its constructional features Fluidomat - SC offers many distinct advantages like:
- Self supported statinary housing, hence no weight experienced by driving or driven shafts and does not load motor and machine bearings.
- Rugged design for all site conditions.
- Rotating mass is not exposed, hence, no hazzards of accidents.
- Easy mountings of various controls, oil connections, sensors etc.
- Higher misalignment capacity and choice of flexible couplings.
- Easy maintenance and accessibility by opening top cover.
- Continuous declutching possible.
- Very low vibration and noise level.
- Ease of adopting various type of control and compatible with them.
- Scoop tube position can be governed very easily for speed control.
- Easy operation of scoop tube in auto or manual mode.
- Labyrinth seals on shaft ensures no leakage from shaft ends.
The sliding scoop tube governs the oil level in the working circuits depending on its (scoop tube) position between 0% to 100%. By varying the oil level in the working circuit the torque transmission capacity of the coupling varies, thus changing the slip of the coupling and provides stepless speed variation in a wide range. The heat generated in the coupling is picked up by the circulating oil which is cooled by oil cooler provided in the oil circiut. Fluidomat SC provides very useful stepless speed regulation in the range of 5:1 for centrifugal loads like fans and pumps, 2:1 for constant torque loads like conveyors and 1.4:1 for rising torque loads. It is also very useful for continuous declutching of machine with motor running.
