The snap-action tripping is positive, precise and repeatable. When the turbine shaft exceeds the selected speed the bolt is instantly released to unlatch the trip valve. The bolt is retained until a pre-selected trip speed is reached. The Overspeed Trip Collar, installed on the turbine shaft, houses an adjustable, spring loaded bolt. It is capable of three consecutive non-trending trip-outs within +/-2% of set trip speed. The independent system stops the turbine under any load condition by activating the force-actuated trip valve. The snap-acting bolt type trip mechanism introduced by COPPUS in the mid 80s set new industry standards for Overspeed Trip Systems. RLVA Over-speed Trip System Meets API 611 standards Configurations are available for a wide range of shaft extensions, thrust bearings and flange mounting arrangement. RLVA turbines are designed to meet API 611, NEMA and marine standards.
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. The RLVA turbine offers all the same features as the RLA with the added benefit of the space saving vertical design. COPPUS turbines are routinely specified by the petroleum, petrochemical, chemical, sugar, paper, food processing and other industries that require continuous or standby emergency power. Coppus Vertical, Radially Split, Single Stage Steam Turbine RLVAįor 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.
