The Fluid Coupling from HMA Flow & Industrial acts like a centrifugal clutch. By driving an impeller, the oil passing from the blades to the driven part, which acts as a driven impeller, transmits the power to the equipment or machine. The oil which fills the fluid coupling transfers the torque and also lubricates moving parts.
Fluid couplings are the easiest and cheapest way of creating a perfectly flexible drive train. This is because no mechanical parts are required between the motor and the equipment or machine being driven. Without mechanical parts, there is practically no wear. The elasticity of the fluid coupling solves problems of power peaks in conventional electric motors and the machines they drive.
Applications include conveyors, crushers, centrifuges and wood chippers. Capacities are available up to 1750 hp /1300 kW. Fluid Couplings from HMA Flow & Industrial are built to perform and last. Advantages include easy start-up, with gradual acceleration of the driven component.
Automatic load speed adjustment on the basis of the synchronous speed of two or more motors of the drive train, which is protected against overloads. Rotational vibrations are hence dampened. The torque transmitted complies with pre-set values.
Direct online start electric motors can be used, without star-delta starters or slip-ring motors, with rheostat fluid couplings for soft-start requirements. The Fluid Couplings from HMA Flow & Industrial are ideal for starting high inertia loads, and can be mounted in-line shaft to shaft or with V-belt pulley.
