9 SMAR/HFAR SMAR / HFAR COUPLING Type AR Fluid Couplings are with annular ring and extra long delayfil chamber. During the initial rotation, the annular ring fills up and the working circuit is partially emptied enabling very low torque transmission during motor run up (acceleration). This enables very quick acceleration of motor speed and quick decay of motor current. This is followed by increase in transmitted torque by gradual emptying of delayfil chamber oil into the working circuit. The torque is builtup gradually and enables controlled acceleration torque to the driven machine. These couplings are very useful for conveyor drives.

23 FLUIDOMAT MTP SYSTEM The operating temperature of MTP is as under: MTP SETTING FUSILE PLUG MELTING TEMPERATURE < c 130 c ± 5 c <140 c 160 c ± 5 c THERMAL PROTECTION 1. FUSILE PLUG: Incase of over heating of the coupling, the fusible plug provided on the coupling melts and oil filled in the coupling is drained off and thus power transmission through the coupling is stopped. Coupling should not be run more than 60 seconds after fusible has melted and oil is drained. Suitable guard must be provided so that the hot oil spray is restricted within the guard. 2. THERMAL TRIPPING ARRANGEMENT: MTP is a mechanical Thermal Switch. In order to avoid loss of operating fluid due to over heating of fluid coupling the mechanical Thermal Switch MTP can be added. However fusible plug with higher response temperature remains on the fluid coupling. MTP consist of a plunger plug screwed on the fluid coupling body. A cam with limit switch are mounted on stationary base frame. On exceeding the set temperature, the plunger plug ejects out a pin which hits the cam and operates the limit switch contact (make or break). Depending on the circuit selected the limit switch signal can be used to switch off the drive motor or activate audio/visual alarm. The plunger plug has to be replaced after activation. MTP system provides valuable safety and environment protection by avoiding spillage and loss of expensive operating fluid. Spillage of operating fluid can be expensive fire and accident hazard due to slippery floors and injury to workmen. 3. NON CONTACT ONLINE TEMPERATURE MONITOR WITH DISPLAY AND RELAY OUTPUT TYPE IRNC: The IRNC operates on Infrared pyrometry and consists of stationery infrared noncontact pyrometer and a precision temperature controller. The noncontact infrared sensor is placed in any direction within 50 mm from body of fluid couplings. The heat emitted by the body is sensor and gives a voltage output which is processed in the base unit and gives relay output on exceeding preset temperature values. Two set points are available which can be used for alarm and trip. IRNC systems provide valuable safety and environment protection by avoiding spillage and loss of expensive operating fluid and fire hazardous hot oil spray. Suggested temperature settings an IRNC system: IRNC Setting Fusible Plug Set Point I Set Point II Melting Temp < 95 c < 105 c 130 c ± 5 c < 125 c < 135 c 160 c ± 5 c Fusible plug must be used along with the system as a backup protection. 22

24 SC Scoop Controlled Variable Speed Fluid Couplings

25 SC Scoop Controlled Variable Speed Fluid Couplings 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. 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. 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. eside 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 builtin safety arrangements make it foolproof during operation. 24

Oil is continuously introduced in the working circuit (11) of fluid coupling through an oil pump. The oil circulates through the working circuit and finally passes to the secondary casing (6) and is collected by a sliding scoop tube (7). The position of scoop tube governs the oil level in the working circuit, thus controlling the speed. The position of sliding scoop tube can be governed through suitable actuator and can also be operated manually. On the input and output ends, suitable flexible couplings are provided for the shafts connections. Labyrinth Seals (10) provided on input and output shaft is an effective barrier and ensures no leakage from shaft ends. REATHER OIL FLOW CIRCUIT DIAGRAM MOTOR SIDE MACHINE SIDE LUE LINE INFEED TO COUPLING LUE LINE FROM SCOOP TUE OIL COOLER FILTER OPERATION: The sliding scoop tube governs the oil level in the working circuits depending on its (scoop tube) position between 0% to 100%. y 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. OIL PUMP 25

In centrifugal machines the discharge of fluid is proportional to the machine speed. The discharge can be varied either by throttle control or by speed control. In throttle control, because additional pressure is exerted therefore the machine requires high energy consumption and also causes high rate wear of pump/fan. On the other hand, if speed of pump/fan is reduced to control the discharge then power demand reduces by cube of speed and therefore large amount of energy is saved. Fluidomat SC offers stepless speed variation in range of 5:1 for centrifugal loads and saves high amount of energy. It thus earns money through energy savings.

Loss The curve 1 Shows the power required by a centrifugal machine at different speeds. In the same figure the power required by the system is shown if Fluidomat SC is used for speed variations. Fluidomat SC is an ideal equipment for speed variations of centrifugal machines & thus discharge control. Slip power losses in the coupling are also shown in the characteristic curve CURVE1 % SPEED POWER REQUIRED FOR CENTRIFUGAL FAN & POWER SAVING Y FLUIDOMATSC % POWER SAVED % INPUT POWER WHEN DAMPER CONTROL USED WHEN VARIALE SPEED FLUIDOMAT SC IS USED POWER SAVED Y FLUIDOMATSC Curve 2 shows the typical example of power saved at different discharge values when Fluidomat SC is used. The power saving can be in the range of 1040% depending on operation and flow requirements. Since Fluidomat SC starts motor on NO LOAD therefore motor can be rated for consumed power and not for starting duty. y reducing the power rating of the motor, energy is further saved due to improved efficiency and power factor of the motor. At the same time, high cost slipring motors can be replaced by rugged squirrel cage motors which are low in cost and require very low maintenance. CURVE2 VOLUMETRIC FLOW % 26
