DESCRIPTION & OPERATING CONDITIONS<br />
1. DESCRIPTION<br />
The TRANSFLUID coupling (K series) is a constant filling type<br />
comprising three main elements:<br />
1 - driving impeller (pump) mounted on the input shaft.<br />
2 - driven impeller (turbine) mounted on the output shaft.<br />
3 - cover, flanged to the output impeller, with an oil-tight seal.<br />
The first two elements can work both as pump and/or turbine.<br />
2. OPERATING CONDITIONS<br />
The TRANSFLUID coupling is a hydrokinetic transmission. The<br />
impellers perform like a centrifugal pump and a hydraulic turbine.<br />
With an input drive to the pump (e.g. electric motor or Diesel<br />
engine) kinetic energy is imparted to the oil in the coupling. The<br />
oil moves by centrifugal force across the blades of the turbine<br />
towards the outside of the coupling.<br />
This absorbs the kynetic energy and develops a torque which is<br />
always equal to input torque thus causing rotation of the output<br />
shaft. The wear is practically zero since there are no mechanical<br />
connections.<br />
The efficiency is influenced only by the speed difference (slip)<br />
between pump and turbine.<br />

2 - EXTERNAL IMPELLER<br />
3 - COVER<br />
4 - FLEX COUPLING<br />
2<br />
The slip is essential to the functioning of the coupling: there could<br />
not be torque transmission without slip! The formula for slip, from<br />
which the power loss can be deduced is as follows:<br />
slip % =<br />
input speed – output speed<br />
input speed<br />
x 100<br />
In normal conditions (standard duty), slip can vary from 1,5%<br />
(large power) to 6% (small power).<br />
TRANSFLUID <strong>couplings</strong> follow the laws of all centrifugal<br />
machines:<br />
1 - transmitted torque is proportional to the square of input<br />
speed;<br />
2 - transmitted power is proportional to the cube of input speed;<br />
3 - transmitted power is proportional to the fifth power of circuit<br />
outside diameter.
FLUID COUPLING FITTED ON ELECTRIC MOTORS<br />
2.1. TRANSFLUID COUPLING FITTED ON ELECTRIC MOTORS<br />
The <strong>fluid</strong> coupling is mainly fitted on triphase squirrel-cage<br />
motors which supply maximum torque at 85% of rated speed.<br />
With direct-on-line starting, these motors absorb approx. 6 times<br />
nominal current.<br />
The result is an increase of: motor temperature, prime costs<br />
(specially with frequent starts) and the overcoming of limits<br />
imposed on many plants by suppliers of electrical energy.<br />
To avoid these inconveniences, some people substitute direct<br />
starting with other methods.<br />
The most usual method is star-delta starting ( ) that reduces by<br />
about 1/3 the absorbed current and torque required by direct<br />
starting. This method does not eliminate high current peaks<br />
during the initial commutation phase, and with high inertia<br />
machines it is necessary to select an oversized motor to deal with<br />
the long acceleration period during starting. With the inclusion of<br />
a TRANSFLUID coupling the motor starts on very low load with<br />
only an instantaneous current peak at switch-on (see Fig. 2).<br />
At start all the torque is available to accelerate the motor and the<br />
driving impeller. In this phase there is 100% slip until the motor<br />
reaches the maximum torque point (200% of nominal torque).<br />
Then the driven member speed increases progressively whilst<br />
slip reduces to its minimum value. (Fig. 1)<br />

Furthemore the <strong>fluid</strong> coupling provides protection against<br />
overload or stalling of the driven machine. In these cases, if the<br />
motor were rigidly connected, stopping of the rotor would occur<br />
immediately with overheating and instantaneous increase of<br />
current to the same values or more, of starting current.<br />
With the <strong>fluid</strong> coupling when these factors occur, the motor<br />
decelerates until 100% of slip is reached (breakdown point).<br />
At this point the absorption of current is considerably less than<br />
the starting current (about 75%). (Fig. 3)<br />

FLUID COUPLING WITH DELAYED-FILL CHAMBER<br />
THE ADVANTAGES OF FLUID COUPLING<br />
2.2 TRANSFLUID FLUID COUPLINGS WITH A DELAYED FILL<br />
CHAMBER<br />
A low starting torque is achieved and, with the standard circuit<br />
in a maximum oil fill condition, <strong>fluid</strong> <strong>couplings</strong> allow not to<br />
overcome 200% of the nominal motor torque. It is possible to<br />
furtherly limit the starting torque down to 160% of the nominal<br />
torque, by decreasing oil fill: this, on the other hand, leads to a<br />
slip and working temperature increase in the <strong>fluid</strong> coupling.<br />
The most convenient technical solution is to have <strong>fluid</strong> <strong>couplings</strong><br />
with a delayed fill chamber connected to the main circuit by<br />
means of valves with calibrated bleed orifices, externally<br />
adjustable from size 15CK (Fig. 4b).<br />
With a simple operation, it is therefore possible to adjust the<br />
starting time.<br />
In a standstill position, the delayed fill chamber contains a part<br />
of the filling oil, thus reducing the effective quantity in the working<br />
circuit (Fig. 4a): a torque reduction is obtained to allow at the<br />
same time the motor to quickly reach the steady running speed,<br />
as if started without load.<br />
During start-up, oil flows from the delayed fill chamber to the<br />
main circuit (Fig. 4b) in a proportional quantity to the rotating<br />
speed.<br />
As soon as the <strong>fluid</strong> coupling reaches the nominal speed, all the<br />
oil flows into the main circuit (Fig. 4c) and torque is transmitted<br />
with a minimum slip.<br />
With a simple delayed fill chamber, the ratio between starting<br />
and nominal torque may reach 150 %. This ratio may be furtherly<br />
reduced down to 120 % with a double delayed fill chamber,<br />
which contains a higher oil quantity, to be progressively<br />
transferred into the main circuit during the starting phase.<br />
This is then fit for very smooth start-ups with low torque<br />
absorptions, as typically required for machinery with large inertia<br />
values and for belt conveyors.<br />
The advantages of the delayed fill chamber become more and<br />
more evident when the power to be transmitted furtherly<br />
increases:<br />
the simple chamber is available from size 11CK, while the<br />
double chamber from size 15CCK.<br />

3. SUMMARY OF THE ADVANTAGES GIVEN BY FLUID<br />
COUPLINGS<br />
– very smooth start-ups<br />
– reduction of current absorptions during the starting phase: the<br />
motor starts with very low load<br />
– protection of the motor and the driven machine from jams and<br />
overloads<br />
– utilization of asynchronous squirrel cage motors instead of<br />
special motors with soft starter devices<br />
– higher duration and operating convenience of the whole drive<br />
train, thanks to the protection function achieved by the <strong>fluid</strong><br />
coupling<br />
– higher energy saving, thanks to the current peaks reduction<br />
– limited starting torque down to 120% in the versions with a<br />
double delayed fill chamber<br />
– same torque at input and output: the motor can supply the<br />
maximum torque also when load is jammed<br />
– torsional vibration absorption for internal combustion engines,<br />
thanks to the presence of a <strong>fluid</strong> as a power transmission<br />
element<br />
– possibility to achieve a high number of start-ups, also with an<br />
inversion of the rotation sense<br />
– load balancing in case of a double motor drive: <strong>fluid</strong> <strong>couplings</strong><br />
automatically adjust load speed to the motors speed<br />
– high efficiency<br />
– minimum maintenance<br />
– Viton rotating seals<br />
– cast iron and steel material with anticorrosion treatment<br />

For frequent starts or high inertia acceleration, it is necessary to<br />
first carry out following calculations. For this purpose it is<br />
necessary to know:<br />

In addition to the heat generated in the coupling by slip<br />
during steady running, heat is also generated (as calculated<br />
above) during the acceleration period. To allow time for this<br />
heat to be dissipated, one must not exceed the max<br />
allowable number of acceleration cycles per hour.<br />

RECOMMENDED OIL AND QUANTITY<br />
SAFETY DEVICES<br />
9. OIL FILL<br />
Trans<strong>fluid</strong> <strong>fluid</strong> <strong>couplings</strong> are not generally filled with oil, so<br />
it is necessary to follow the procedure reported here below to<br />
achieve the standard fill X for K series, fill 2 for CK series and fill<br />
3 for CCK series:<br />
1 - position the <strong>fluid</strong> coupling axis horizontally, turn it until the X<br />
mark (respectively 2 or 3 according to the <strong>fluid</strong> coupling type)<br />
cast into the housing gets at the top vertical (maximum oil fill),<br />
so that the oil plug is inclined as shown in Fig. 5.<br />
2 - fill with oil until it overflows out of the filler hole. While filling,<br />
gently rock the coupling on its axis to make sure all air excess<br />
is vented out of the circuit. The quantities to be introduced are<br />
those reported in Tab. E.<br />
3 - screw the cap and make sure no leakages occur; otherwise<br />
use thread sealant on filler plug threads.<br />
4 - the fillings marked X-1-2-3-4 may be chosen by the operators<br />
to meet the best performance in terms of start-up and steady<br />
running condition.<br />
5 - for normal operating conditions, use only ISO HM 32 (or<br />
equivalent SAE 10W).<br />
At low ambient temperatures (near 0°C), it is recommended to<br />
use ISO FD 10 (or equivalent SAE 5W) oil.<br />
For temperatures below –10°C, ask Trans<strong>fluid</strong>.<br />
6 - for vertical mounted applications, the <strong>couplings</strong> recommended<br />
oil fills are reported in Tab. E.<br />

10. SAFETY DEVICES<br />
FUSIBLE PLUG<br />
In case of overloads, or when slip reaches very high values, oil<br />
temperature excessively increases, damaging oil seals and<br />
letting oil out.<br />
To avoid damage, for severe applications it is advisable to fit a<br />
convenient fusible plug. Fluid <strong>couplings</strong> are supplied with a<br />
fusible plug at 145°C (120°C, 175°C or 198°C upon request).<br />
SWITCHING PIN<br />
Oil leakage out of the fusible plug may be avoided with the<br />
installation of a switching pin device. When the temperature<br />
reaches the melting point of the fusible ring element, this<br />
releases a pin that intercepts a relay cam, giving an alarm or<br />
stopping the main motor supply.<br />
As for the fusible plug, 3 different fusible rings are available (see<br />
page 25).<br />
ELECTRONIC OVERLOAD CONTROLLER<br />
It consists of a proximity sensor measuring the speed variation<br />
between input and output of the <strong>fluid</strong> coupling, giving an alarm<br />
signal or stopping the motor in case the set threshold is<br />
overcome.<br />
With such a device, as well as with the infrared temperature<br />
controller, no further maintenance or repair intervention is<br />
necessary after the overload situation, because the machinery<br />
can regularly go on, once the cause of the inconvenience has<br />
been removed (see page 26).<br />
INFRARED TEMPERATURE CONTROLLER<br />
To measure the operating temperature, a device fitted with an<br />
infrared sensor is available. After conveniently positioning it by<br />
the <strong>fluid</strong> coupling, it allows a very precise non-contact<br />
temperature measurement.<br />
Temperature values are reported on a display that also allows the<br />
setting of 2 alarm thresholds to be used by the customer (see<br />
page 27).<br />

SAFETY DEVICES<br />
OPERATION<br />
10.1 SWITCHING PIN DEVICE<br />
The device includes a fusible switching pin, fitted on the <strong>fluid</strong><br />
coupling cover, and a relay to be positioned according to the<br />
distances shown in Fig. 6.<br />
The switching pin is formed by a threaded plug and a pin held in<br />
place by a fusible ring: the pin comes out owing to centrifugal<br />
force when the temperature set for the fusible ring melts it.<br />
The temperature increment may depend on an overload, a jam in<br />
the driven machine or an insufficient oil fill.<br />
The pin, sliding about 16 mm, intercepts the cam of the relay to<br />
give an alarm or a motor stop signal.<br />
After a possible intervention, and after removing the cause, the<br />
device may be easily reset by replacing the threaded plug or<br />
even the fusible ring, following the specific instructions reported in<br />
the installation manual.<br />
The switching pin device is generally to be required when<br />
ordering, as the <strong>fluid</strong> coupling cover needs a convenient<br />
machining and balancing.<br />
In case it needs to be fitted on a pre-existing plant which was not<br />
equipped with it, the replacement of the whole cover fitted with a<br />
switching pin is recommended.<br />
To increase safety on <strong>fluid</strong> <strong>couplings</strong>, a standard fusible plug set<br />
at a higher temperature than that of the switching pin, is always<br />
present.<br />
For a correct operation, see also the technical features relative to<br />
standard or reverse mountings, reported at page 28.<br />

OPERATION<br />
10.2 OVERLOAD CONTROLLER<br />
When load torque increases, slip also increases and output<br />
speed consequently decreases.<br />
The said speed variation can be measured by means of a sensor<br />
sending a pulse train to the speed controller. If the rotating speed<br />
goes lower than the set threshold (see diagram) on the controller,<br />
a signal is given through the intervention of the inner relay.<br />
The device has got a “TC” timer with a blind time before starting<br />
(1 - 120 s) avoiding the alarm intervention during the starting<br />
phase, and another “T” timer (1 – 30 s) preventing from<br />
undesired relay intervention during sudden changes of torque.<br />
The device also provides a speed proportional analogic output<br />
signal (0 – 10 V), to be forwarded to a display or a signal<br />
transducer (4 – 20 mA).<br />
Standard supply is 230 V ac, other supplies are available upon<br />
request: 115 V ac, 24 V ac or 24 V dc, to be specified with the<br />
order.<br />

OPERATION<br />
10.3 INFRARED TEMPERATURE CONTROLLER<br />
This is a non contacting system to check <strong>fluid</strong> coupling<br />
temperature. It is reliable and easy-mounting.<br />
It has 2 adjustable thresholds with a logical alarm on the former,<br />
and a relay alarm on the latter.<br />
The proximity sensor must be positioned near the <strong>fluid</strong> coupling<br />
outer impeller or cover, according to one of the layouts shown in<br />
Fig. 9.<br />
It is adviced to place it in A or C positions, as the air flow<br />
generated by the <strong>fluid</strong> coupling during rotation helps to remove<br />
possible dirt particles that may lay on the sensor lens.<br />
The distance between the sensor and the <strong>fluid</strong> coupling must be<br />
about 15-20 mm (cooling fins do not disturb the correct operation<br />
of the same sensor).<br />
To avoid the bright surface of the <strong>fluid</strong> coupling to reflect light,<br />
and thus compromise a correct temperature reading, it is<br />
necessary to paint the surface which is directly facing the sensor<br />
of a flat black colour (a stripe of 6-7 cm is sufficient).<br />
The sensor cable has a standard length of 90 cm. In case of<br />
need, a longer one may be used only if plaited and shielded as<br />
per type “K” thermocouples.<br />

STANDARD OR REVERSE MOUNTING<br />
11. INSTALLATION<br />
11.1 STANDARD MOUNTING<br />
Driver inner impeller<br />
Minimum possible inertia is added to the motor, that is therefore<br />
free to accelerate more quickly.<br />
During the starting phase, the outer impeller gradually reaches<br />
the steady running condition. For very long starting times, heat<br />
dissipation capacity is lower.<br />
If a braking system is required, it is convenient and easy to<br />
install a brake drum or disc on the flex coupling.<br />
For the very few cases in which the driven machine cannot be<br />
rotated by hand, maintenance procedures of oil checking and<br />
refilling, as well as alignment, become more difficult.<br />
The delayed fill chamber, when present, is fitted on the driven<br />
side. The rotating speed of the said chamber gradually increases<br />
during start-up, thus leading to a longer starting time, given the<br />
bleed orifices diameters are not changed. If oil quantity is<br />
excessively reduced, the transmissible torque may be lower<br />
than the starting torque of the driven machine. In such a case,<br />
part of the oil remains inside the delayed chamber. This lack of oil<br />
in the <strong>fluid</strong> coupling may prevent starting the <strong>fluid</strong> coupling up.<br />
The “switching pin” device might not work correctly on<br />
machines where, owing to irregular operating conditions, the<br />
driven side may suddenly stop, or jam during the starting phase.<br />
Flex coupling is protected by the presence of the <strong>fluid</strong> coupling in<br />
front of it, and therefore this configuration is fit for applications<br />
with frequent start-ups or inversions of the rotating sense.<br />
28<br />
11.2 REVERSE MOUNTING<br />
Driver outer impeller<br />
Higher inertia directly connected to the motor.<br />
The outer impeller, being directly connected to the motor,<br />
reaches synchronous speed at once. Ventilation is therefore<br />
maximum from the beginning.<br />
The assembly of a brake disc or drum on KR <strong>fluid</strong> <strong>couplings</strong> is<br />
more difficult and expensive, and leads to a longer axial<br />
dimension of the whole machine group.<br />
The outer impeller and cover are connected to the motor, it is<br />
therefore possible to manually rotate the coupling to check<br />
alignment and oil level, and for refilling.<br />
The delayed fill chamber is fitted on the driver side, and reaches<br />
the synchronous speed in a few seconds.<br />
Oil is therefore centrifuged into the main circuit gradually and<br />
completely.<br />
Starting time is adjustable by replacing the calibrated bleed<br />
orifices.<br />
The starting phase, however requires a shorter time than that<br />
needed in the configuration with an inner driver impeller.<br />
The switching pin operation is always assured, as the outer<br />
impeller, where fitted, always rotates because it mounted on the<br />
driver shaft.<br />
In case of frequent start-ups or inversions of the rotating sense,<br />
the flex coupling is much more stressed.<br />
If not expressely required by the customer or needed for the application being performed, the <strong>fluid</strong> coupling is supplied according to<br />
our “standard” mounting. Do specify in your quotation request whether you need a “reverse” mounting.<br />
NOTE: Starting from size 13 included, a baffle ring is always fitted on the driver impeller, and therefore it is not recommended to<br />
“reverse” mount a <strong>fluid</strong> coupling foreseen with a “standard” mounting, and viceversa.<br />
In these cases contact Trans<strong>fluid</strong> for more detailed information.
