Turbomachinery Package Specification Taurus 60 Compressor Set and Mechanical Drive
5 Mechanical Drive Packages
5.1 Mechanical Drives
The Taurus 60 gas turbine mechanical-drive package is designed for a variety of driven
equipment, including centrifugal pumps and centrifugal, rotary, and reciprocating
compressors. The Taurus 60 gas turbine is well suited to drive pumps and compressors,
where its variable-speed capability can be used to advantage in adjusting to changing
specific gravity and flow.
Solar's mechanical-drive units are widely used for crude oil or liquid product pumping and
water flooding applications. As an option, Solar can provide a gear to match the speed of
the driven equipment to that of the gas turbine. The gear can be located either on the
driven equipment skid or on a separate skid between the driver and driven equipment
skids.
5.1.1 Unitized Packaging
While the gas turbine driver package can be supplied separately for integration by others
into a complete system, Solar also offers unitized packages. When a unitized package is
supplied, Solar’s scope of supply may include the following options:
Driven Equipment
Supplied by original equipment manufacturers in compliance with customer requirements
and Solar’s procurement specifications.
Mating Baseplate
The separate structural steel driver skid and driven equipment skid (optional) have
mating flanges so they can be rigidly bolted together at the installation site. The skids
may also be bolted and dowelled together at the factory and then separated for shipment.
Shaft Coupling
Several supplier-furnished shaft coupling styles are available. Coupling hubs may be
mounted on both shafts at the factory. A coupling guard is included.
Preliminary Alignment
A preliminary alignment of the gas turbine driver and the driven equipment shafts can be
performed at the factory to simplify final field alignment.
Unitized Lubrication and Cooling
On packages using compressors or pumps with sleeve or tilt-pad bearings, the bearings
may be force fed with cooled oil from the gas turbine lubrication system. Pumps with anti-
friction bearings are usually furnished with self-contained ring oiling and the oil is cooled
by the product being pumped.
Unitized Controls
Driven equipment protective devices may be integrated into the package control system
to provide alarms and shutdowns for a variety of abnormal operating conditions, including
low suction and high discharge pressure, seal leakage, high bearing or case temperature,
excessive vibration, or any other measurable quantity. Additionally, driven equipment
valving (suction, discharge, bypass, vent) may be integrated into the start-up and
shutdown sequence controls, so those valves are automatically actuated and monitored.
Additional digital and analog values can also be monitored by the control system.
