What is the pressure at which the GTM fuel pump HP relief valve is designed to relieve?

The high-pressure relief valve of the Gas Turbine Module (GTM) fuel pump is specifically designed to relieve excess pressure to ensure that the fuel system operates within safe and optimal limits. The correct pressure at which this relief valve is calibrated to operate is 1,350 pounds per square inch (PSI).

This pressure setting is critical because it helps prevent potential damage or failure of the fuel system, which could occur if the pressure exceeds design specifications. When the pressure reaches 1,350 PSI, the relief valve opens to allow excess fuel to bypass, thus maintaining the pressure within the system at a level that is stable and safe for operation.

Understanding this threshold is essential for technicians to monitor the performance of the turbo machinery and ensures that fuel flow is maintained without risking damage to the components involved. This knowledge is vital for troubleshooting and maintenance in gas turbine operations.
