Drive systems manufacturer Voith Turbo is offering industry a range of torque convertors that is suited to motors that are sensitive to power absorption and high-speed applica- tions.
The torque convertors are suitable for the oil and gas, the mining, the energy and materials handling industries, where it is required that either the speed or the torque be controlled in processes or applications.
Voith Turbo energy, oil and gas divisional manager Derain Pillay says the range of torque convertors has a proved, compact and robust design, with a reliability of 99.99%.
“This hydrodynamic torque convertor, with combined speed and torque variation, is mainly used on hyperbolic or constant torque applications, or any mixed characteristic. The liquid flow, produced by the pump, drives the turbine and the power is constantly con- trolled by the convertor, which decreases output speeds, resulting in energy savings,” he explains.
The convertors, which are manufactured in Germany, have a power range greater than 10 000 kW, a speed range of more than 140% and torque of above 240%.
The convertors are easy to install and have a low capital and maintenance cost and a wide operating range. They also do not cause any electrical harmonics issues.
Pillay says the shock and vibration dampening ensure the risk of downtime is reduced, as overload protection motors control risk areas.
New manufacturing mate- rials have been used to reduce the product’s weight, com- bined with a patented guide vane design that improves the efficiency of the torque con- vertor.
“Voith Turbo convertors are constantly being upgraded and enhanced with the latest technology. Voith spends 5% of yearly turnover on research and development to ensure all our products are constantly at the leading edge of tech- nology,” he says.
No special tools are required for installation; the units require minimal maintenance and have a high reliability factor, which reduces unforeseen breakdowns and stoppages.
