New Vorecon NX from Voith: Efficiency in the Lower Speed Range
Increased by up to Eight Percent
Voith expands the Vorecon portfolio
with the NX series for low power ranges
The delivery time of the new
type is only six months

2016, June 24 + + + The Vorecon variable speed
planetary gear from Voith provides speed control with maximum reliability
and low life cycle costs (LCC) in the oil and gas industry. With the new
NX series, Voith has now further developed the proven principle
specifically for applications in the low power range up to 10 MW. The
Vorecon NX provides an increase in efficiency of up to eight percent in
part load. Additionally, it impresses with an attractive price, low total
costs of ownership (TCO) and well-known reliability.
The Vorecon is
used throughout the entire value-added chain of the oil and gas industry,
controlling the speed in upstream, mid-stream and downstream applications.
With the new Vorecon NX Voith is strengthening this portfolio in the area
of pipeline compressors. In the new series, an optimized torque converter
provides efficient speed control. In accordance with the proven Vorecon
superimposing principle, this uses only a small part of the input power.
Depending on the speed required, this power is fed back to the driveline
by way of the planetary gear on the driven side. Adjustable pump blades in
the torque converter provide the control – stepless and wear-free.
In the Vorecon NX a helical gear on the output side adapts the output
speed to the compressor. This allows a modular design with a standardized
speed control system. As a result, Voith can provide components faster and
reduces the future delivery time of the new Vorecon to only six months.
Within the Vorecon portfolio, the NX series covers power ranges up to
10 MW. Like the entire product family, the new type also has an integrated
working and lubrication oil system. This system fills the torque converter
and supplies its own gearbox, the drive motor and the driven machine with
lubrication oil in parallel.
The Vorecon controls the speed of
compressors and pumps. The lifetime of the hydrodynamically controlled
planetary gear is several decades. With its statistical reliability of
99.98 percent and a Mean Time Between Failure of 48 years, it avoids
unscheduled downtime of the drive system and the associated costs.
Voith Turbo, a Group Division of Voith GmbH, is a specialist for
intelligent drive solutions. Customers from highly diverse industries such
as oil and gas, energy, mining and mechanical engineering, ship
technology, rail and commercial vehicles rely on advanced technologies
from Voith Turbo.
