Coppus Horizontal, Axial Split, Single Stage Steam Turbine RLHB

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 RLHB offers anti-friction journal bearings, in place of the split sleeve bearings found on the RLHA, for applications where quick starts are required. The RLHB also takes advantage of oil ring or oil mist lubrication systems, eliminating the need for higher cost forced feed lubrica-tion for speeds up to 5,000 RPM. Specifications: • Wheel Diameter 15" - 28" • Max Power 450 - 4000 HP (333 - 2980 kW) • Max Speed 5500 - 6300 RPM • Max Inlet Pressure 600 - 900 PSIG • Max Inlet Temperature 400 - 570°C • Max Outlet Pressure 105 - 300 PSIG • Inlet Diameter 3" - 6" • Exhaust Diameter 6" - 10" RLHB 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
