KPTO: VARIABLE FILL FLUID COUPLINGS

Standard accessories include oil feeding pump, oil filter with pressure and temperature gauges, ON-OFF electric valve, oil temperature switch, and oil level indicators.
Optional accessories include water or air heat exchanger, quick release valves, output pulleys, elastic couplings, output flange for Cardan shafts, and Cardan shafts too.

FEATURES

The KPTO drain type fluid coupling allows a disconnect or the engine from the load granting the following advantages:

• unloaded engine warm-up
• smooth start-up, no belt slip
• shock and overload protection
• absorption of vibration
• high radial load capacity
• remote control by electric valve
• load positioning
• cheap and easy maintenance due to external mounting of the main accessories like oil filter, feeding pump and control valve
• longer life thanks to no friction linings to wear out

ACCESSORIES

MPCB

The management system MPCB is a device developed by TRANSFLUID, both in the hardware and software, able to manage the different functionalities of KPTO fluid coupling; it allows the engagement or disengagement of the KPTO depending on the different operational profiles, measures the torque and the power transmitted from the coupling and performs the task of system diagnostics.

EXAMPLES OF OUR APPLICATIONS

17 KPT

The pulley on the output shaft runs a crusher.
On the input shaft an elastic coupling is mounted which is attached to an internal combustion engine. The pulley on the input shaft operates a small generator of the crusher.

The principal characteristics are:
– soft start
– disconnecting
– protection from shock and overloads
– no components subject to wear from the transmission of power
– simple maintenance reduced to only the minimum
– sturdy and reliable operation

19 KPT

Transmission for a mill that prepares raw material to produce ceramic tiles.

The fluid coupling transmits the power through a 90° gearbox by a series of belts to operate the crusher.
The KPT allows the connect and disconnect of the crusher and continually absorbs the shock and overloads typical of this application.
The increase in the life of the belts and gearbox and the reduction in fuel consumption is only a few of the many advantages of the KPT.
The versatility and sturdiness of the KPT fluid coupling make it particularly adapted for heavy-duty installations where a normal PTO would be damaged in a short period.
The maintenance requirements are another high point of the coupling. In fact, only a periodic substitution of the oil and filter are required.
There are no special regulations or greasing needed and there are no frictional power transmitting parts to replace.
Wood Chipper.
The group mounted on a wood chipper during the revisional phase of the machine.
Shredder operated by an endothermic engine where the KPT hydrodynamic coupling, in addition to allowing a gradual start of the heavy rotor, absorbs the inevitable shocks and continuous overloads typical of this type of operating machines.The versatility and strength of the KPT hydrodynamic joint make it particularly suitable for heavy-duty applications where normal friction power take-offs would be irreparably damaged in a short time.For this type of machine, it is not always possible to have a specialized technician available to carry out maintenance.The KPT hydrodynamic joint only requires periodic replacement of the oil filter cartridge and the oil.There are no adjustments or greasing to be carried out, there are no friction components to be replaced or regenerated.For machines intended for rental, maintenance is often neglected by users, it is necessary to choose components that guarantee maximum reliability in the most demanding conditions and that can work for a long time without continuous adjustment, greasing, and maintenance operations.The KPT hydrodynamic joint fully meets these requirements.

19 KPT – 2

Wood chipper.
Transmission to a wood chipper from an internal combustion engine.
The KPT coupling transmits power through pulleys mounted directly on the output shaft.
The overloads and spikes typical in these applications are absorbed thus protecting the transmission.

21 KPT

Command group for a crusher powered by an internal combustion engine.
In this application the noise level of the KPT is small enough to eliminate the need to extend the sound absorbing cover of the motor.
It can be noted the compact nature of the KPT which is very convenient in limited space applications.

24 KPT

Main drive group for a large crusher.
In these applications normal power take-offs are not recommended, however, the KPT coupling is well suited.
The numerous advantages available from a KPT are seen throughout the drive chain by protecting and increasing the life of the system.
These advantages reduce downtime and maintenance time.
Thousands of applications have demonstrated the high sturdiness, reliability, and validity of the Transfluid fluid couplings.
Transfluid fluid couplings increase the life of the entire drive chain because of its capabilities to absorb shock loads, overloads, and torsional vibration.
The coupling’s properties also reduce exhaust fumes and fuel consumption.
While running, and during jams caused by operator error, the KPT functions as a torque limiter avoiding costly transmission problems and long down
periods for repairs.
Centrifugal pump control for a small tanker to pump hydrocarbons.
The KPT coupling receives its input from the opposite side of the internal combustion motor and runs a centrifugal pump for the movement of hydrocarbons.
During normal operation the motor serves as the ship’s propulsion and therefore the KPT operates as a clutch. When pumping is required the KPT is connected gradually by an electro valve.
It is possible to operate as a starter or as a speed controller.

24 KPT – 2

A stationary drive train for crusher.
In this application, since the loads were high, caused by a small pulley with many belts, the pulley was mounted between bearings and connected to the fluid coupling through a toothed coupling.
In most cases the pulley is mounted directly on the KPT output shaft which has a high radial load capability.
Transfluid asks for necessary application data to calculate the bearing life for each application.

24 KPT – 3

A drive system for a crusher powered by an internal combustion engine. It is obvious the relatively small dimension of the KPT in the system which is comparable to a power-take-off with friction plates (photo 1). The installation is very simple as the KPT is directly flanged to the flywheel housing and coupled to the motor through a special elastic coupling with high elasticity, eliminating the need for a pilot bearing mounted in the flywheel. The crusher is powered by a pulley directly mounted on the KPT output shaft (photo 2). The size of the pulley clearly indicates the capacity of the KPT to support radial loads.
With the installation characteristics, Transfluid can calculate the bearing life of the application.
In applications where the traditional power take-off with friction plates is not recommended the KPT is the obvious choice.
Numerous advantages are introduced by the use of the KPT, and these advantages are realized throughout the drive train.
These advantages include the protection of the drive train and a reduction in downtime. Thousands of applications in different sectors have demonstrated the sturdiness and high reliability of the Transfluid fluid coupling.
The dimensions of the fluid coupling are very compact when compared to that of the internal combustion engine or the complete machine.
These characteristics make it possible to use in limited spaces where the machine cannot exceed certain limits because the equipment must circulate on normal roads.
