Coppus Vertical, Radially Split, Single Stage Steam Turbine RLVA

For over 80 years COPPUS steam turbines have been recognized around the world as rugged, versatile drive solutions for lube oil pumps, feed water pumps, fans, generators and other mechanical drive applications. COPPUS turbines are routinely specified by the petroleum, petrochemical, chemical, sugar, paper, food processing and other industries that require continuous or standby emergency power. The RLVA turbine offers all the same features as the RLA with the added benefit of the space saving vertical design. Available in 8 frame sizes to meet a wide variety of applications that includes pump drives for on board ships, and pump and fan drives for oil refineries, gas pipelines and other industries where space is limited. RLVA turbines are designed to meet API 611, NEMA and marine standards. Configurations are available for a wide range of shaft extensions, thrust bearings and flange mounting arrangement. Specifications: • Wheel Diameter 12" - 22" • Max Power 60 - 1000 HP (44 - 745 kW) • Max Speed 4000 - 6000 RPM • Max Inlet Pressure 670 - 700 PSIG • Max Inlet Temperature 440°C • Max Back Pressure 105 - 165 PSIG • Inlet Diameter 3/4" - 4" • Exhaust Diameter 3" - 8" RLVA Over-speed Trip System Meets API 611 standards The snap-acting bolt type trip mechanism introduced by COPPUS in the mid 80s set new industry standards for Overspeed Trip Systems. The independent system stops the turbine under any load condition by activating the force-actuated trip valve. It is capable of three consecutive non-trending trip-outs within +/-2% of set trip speed. The Overspeed Trip Collar, installed on the turbine shaft, houses an adjustable, spring loaded bolt. The bolt is retained until a pre-selected trip speed is reached. When the turbine shaft exceeds the selected speed the bolt is instantly released to unlatch the trip valve. The snap-action tripping is positive, precise and repeatable. The Overspeed Trip Valves are designed to minimize pressure drop ensuring the highest available pressure at the nozzle ring for doing work. When released by the Overspeed Trip mechanism or the manual trip lever the valve is instantly closed to shut off steam. The single-seated valve will bring a fully, unloaded turbine to a complete stop. For manual resetting against full-line pressure, a pilot valve relieves unbalanced pressure. Standard features on COPPUS Turbines include: • Meet or exceed strict API 611 requirements • Overspeed mechanical trip valve • Snap-acting overspeed trip • Woodward TG direct drive oil relay governor • Constant level sight-feed oilers • Stiff shaft construction with single disc wheel located between bearings • Manual speed changer • Single piece contoured Curtis type wheel Optional Features for COPPUS Turbines Include: • Forged steel wheels • Special shaft materials • Part load and overload hand valves • Kingsbury? thrust bearings • Copper free construction for corrosive atmospheres • Single row wheels • Lagging, "blanket type" insulation • High back pressure construction • Electronic or hydraulic NEMA Class D governors and variable speed controls • Solenoid trips for remote shutdown • Extended inlet pressure and temperature constructions
