Taurus 60 Compressor Set and Mechanical Drive

 

 

5 Mechanical Drive Packages

5.1Mechanical 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.

5.1.1Unitized 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.
