Fuel Nozzle Cleaning and Flow check
Regular maintenance, including Cleaning and flow checking the fuel nozzles of Pratt & Whitney PT6A Engine is a crucial maintenance task that ensures proper fuel atomization and combustion enhancing engine reliability, performance & longevity. This is a scheduled maintenance carried out every 400 hours in accordance with PWC Maintenance Manual.
Poor nozzles flow reduces the Hot Section life & stresses the Vein ring , Turbine blades and accelerating erosion of combustion chamber liners, small & large exit ducts. These issues not only raise maintenance costs & increase downtime but also pose significant safety risks during flight.
What does SAMEL do?
At SAMEL , we implement rigorous standards for fuel nozzle flow patterns to guarantee optimal fuel delivery to your engine thereby enhancing efficiency & ultimately lowering operating expenses.
Our experienced Engineers & Technicians inspect each and every crevices for streaks. Using the appropriate Engine Maintenance Manual procedures;
- The fuel nozzles are soaked & cleaned with an ultrasonic machine.
- The team carries out flow check test using the pressure test rig to ensure the nozzles are providing the correct fuel flow rate while carefully recording any anomalies in the spray pattern, which may indicate clogging or damage of the nozzle tip.
- A leak test is carried out to ensure that the fuel nozzles are not leaking maintaining proper fuel flow without allowing unintended fuel escape.
