The advantage of pure water as operating medium of a fluid coupling lies in its environmental friendliness. “The water operated fluid couplings have proven themselves as reliable couplings for sensitive environmental areas,” explains Voith Turbo South Africa’s Product Manager, Start-up Components, Hans Voshol.

 

Constant-fill fluid couplings from Voith are used with electric motors in a wide range of applications, especially when highest powers, economy and reliability are required. 

 

The range of constant-fill couplings is perfectly engineered to meet demanding conveyor drive applications with high capacities and lengths in bulk materials handling and processing industries. 

 

Constant-fill fluid couplings contain a constant quantity of operating fluid, usually mineral oil but water or fire-retardant fluids are also used. The torque transmitted by the drive motor is converted into kinetic energy of the operating fluid in the pump wheel to which the motor is connected. In the turbine wheel, this kinetic energy is converted back into mechanical energy. The housings are either Silumin or speroidal cast iron. 

 

Fluid couplings contribute to a start–up component that is smooth and reliable. Perfectly engineered for demanding drives in materials handling and processing industries, the water operated couplings perform efficiently under the most stringent operating conditions.  

 

The couplings incorporate a number of outstanding characteristics to ensure efficient, safe and economical operation. They limit the introduced torque during start-up and accelerate the working machine smoothly.  The fluid couplings provide a nearly load-free start-up and run-up of the motor. Voshol adds that the couplings are suitable for economically priced squirrel cage motors and no motor modification is required. During operation the couplings absorb shocks and vibrations. Compensation and step starting for multi-motor drives and higher thermal capacity and heat dissipation offer the highest possible operating safety.

 

“There is a constant need to reduce costs, irrespective of industry, and the water operated couplings as well as all Voith fluid couplings deliver prolonged service life of the system, lowers maintenance costs and reduces the risk of unplanned down time,” concludes Voshol.
