The fluid quantity in the working circuit is less than in traditional constant fill fluid couplings, as the fluid level is much lower than the rotating axie. The reduced fluid quantity in the working circuit allows low starting torque. During input rotation the scoop transfers the fluid from tank A to tank B and then, through an adjustable valve for starting time regulation, to the working circuit.
Starting stall torque below 50% of the electric motor nominal torque.
Starting torque limitation also below the nominal torque.
KX allows the fluid coupling removal without moving the electric motor or the driven machine avoiding the realignment.
KX has a fusible plug that in case of intervention, releases the fluid from the working circuit to a tank preventing leakages into the ambient.
A steel body design suitable for underground mines is available.
The fluid filling operation is quite easy and apart from some particular cases, it is not required to change the fluid during the test start: the starting time can be optimized by changing on the externally adjustable valves.
KX fluid coupling is very suitable for driving machines having large powers and inertia: typical applications are mills and belt conveyors
They are also available certified according to directive 94/9/EC (Atex) covering all categories.
