Abstract

In a steam turbine driven pump installation, the steam flow to the turbine is controlled by a combined stop and throttle valve which includes a power operated actuator so as to vary the output of the pump, and a speed feed-back control is provided for the turbine comprising an indicator issuing a signal corresponding to the turbine speed, and a comparator comparing the speed signal with a desired value and delivering a control signal based on the comparison to a servo-device of the valve actuator for adjustment of the valve whereby turbine speed may be maintained constant. Additionally the installation includes an emergency control respondent to operating conditions in the installation e.g. turbine overspeed, oil pressure etc., the emergency control including a switch in the power supply to the valve actuator whereby in the event of the operating condition being unsatisfactory the switch is opened to close the steam valve.
