The system consists of a 24 liters tank, strainer, level indicator for measuring the level manually, filler breather. The system is operating at a pressure from to 10 Kg/cm ².The test bench consists of pump and motor coupled through Coupling and Bell Housing. Set for Aero Engine Preservation is a device that pumps inhibiting fuel into the Inhibition port of the Aero engine (Air Force). Traditionally, the pump is driven directly by the 28 V DC motor coupled to the Pump through Bell- Housing and Coupling. Set for Aero Engine Preservation is used to inhibit the fuel in Aero engines. The Pump delivers a flow of 800 liters/hour at 0-3 Kg/cm² to the engine. The level of oil in tank is indicated through Level Indicator mounted on the Tank. The filtered oil is supplied to the engine through the delivery hose. The Rig is portable as it has a wheeled Base, the tank is Cylindrical and it makes the Rig compact. The whole rig looks like a Trolley. The total weight of our system is 110 kg approximately. Working Medium: OM-11 Operating Pressure: 0.8 to 10 Kg/cm ² (Adjustable). Drive Motor: 0.35 KW. Tank capacity: 24 liters. Preserving Oil temp.: 50- 70 °C Consumed DC Voltage: 28 V
