TURBO COUPLING – HYDRAULIC COUPLING
The KPTO is a variable fill fluid coupling enclosed into a box connected to the Diesel engine by SAE housing. The KPTO is designed to meet the market requirements for a unit combining the technical features of a conventional Power Take Off with a fluid coupling’s performance. The KPTO has an integral feeding pump driven by the Diesel engine.
A remote electrically operated ON-OFF valve allows the fluid coupling circuit feed when turned ON and a rapid oil drain through orifices located on the periphery of the fluid coupling when turned OFF.
The forced bearing lubrication is continuously assured.
The the KPTO range is suitable for powers up to 1000 kW.
The engine flywheel is connected to the KPTO input by an elastic coupling. The output shaft can be connected to the driven machine by elastic coupling, cardan shaft or pulley.
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.
HYDRAULIC COUPLING – FEATURES
The KPTO drain type fluid coupling allows a disconnect of the engine from the load granting the following advantages:
- unloaded engine warm-up
- smooth start-up, no belt slip
- shock and overload protection
- absorbtion 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 AVAILABLE FOR THE KPTO VARIABLE FLUID COUPLING
MPCB MANAGEMENT SYSTEM
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.
HYDRAULIC COUPLING – APPLICATIONS
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 principle characteristics are:
– soft start
– protection from shock and over loads
– no components subject to wear from transmission of power
– simple maintenance reduced to only the minimum
– sturdy and reliable operation
