SYSTEM AND METHOD FOR REGULATING PRESSURE FOR A TURBOMACHINE

摘要

A pressure regulating system which is an arrangement with a turbo machine for example a nuclear steam turbine. Main lubricant oil pump supply fluid for example lubricant oil to the nuclear steam turbine passes through a cooler and via filter through a main supply line. The pressure regulating system is connected to the main supply line through an actuating line. Based on requirement of the fluid excessive fluid can be diverted through the actuating line to the pressure regulating system and from there to oil tank. In oil tank an auxiliary lubricant oil pump is provided to supplement the supply of the lubricant oil to the nuclear steam turbine. An emergency lubricant oil pump has also been provided to supply the lubricant oil to the nuclear steam turbine in case when regular supply is not working.

1. A pressure regulating system for a turbo machine comprising
a body member having a moving member, an opening and a sealing member, a first biasing member to keep the moving member at a closed position, an actuating line, extended from a main supply line to the pressure regulating system, for actuating on the moving member to counter the bias member by filing pressurized fluid into a manifold permitting the pressure of the pressurized fluid to increase to a preset value in the manifold, an impulse line, extended from the pressure regulating system to the main supply line for supplying the pressurized fluid in at least one chamber of the moving member to lift the moving member to an open position, leads to opening of the sealing member to drain the manifold through the opening.
