- Description
- Aircraft Brake Assembly Test Stand Hydraulic System The Skydrol 500B or other similar hydraulic fluid required for operation of the test stand is contained in a 10-gallon stainless steel reservoir. The reservoir includes a fluid sight level gauge. Hydraulic fluid from the reservoir flows to the inlet of an electrically powered pump delivering up to 3 GPM at up to 300 PSIG. A pneumatically driven, static high pressure supply pump provides up to 0.5 GPM at up to 4600 PSIG. The test stand?s high flow, low pressure system is used for bleeding and flushing the brake assemblies and the high pressure, low flow system is used for pressure testing the brake assemblies. Included in the hydraulic supply circuits are a 100-Mesh strainer, a 3 micron filter, a pressure supply shutoff valve, flow control ball valves, a bypass valve to control supply pressure to the brakes and a back pressure control valve that can be adjusted to maintain the minimum back pressure that some brake assemblies require. The test stand includes a return circuit to facilitate flushing and bleeding of the brake assemblies. The circuit includes a check valve and a sight glass to observe air bubbles (aeration) in the fluid when bleeding brake assemblies. Pneumatic System Customer supplied shop air capable of providing 75-125 PSIG is connected to the test stand. The shop air is filtered to 5-micron within the test stand. An air hose is provided in the test sink area for air tools or an air blow-off nozzle. Electrical System A 115 or 230 VAC (customer-specified), 1 phase, 50/60 Hertz power supply is required to power the hydraulic pump motor. Control and instrument power is generated and distributed within the test stand as required. The test stand is equipped with a ?power-on? light and a control power switch to control the low pressure supply pump. and the cycling of the brake supply pressure. As an option, cycling o test pressures may controlled automatically by the addition of a PLC and pressure transducers to the test stand. Otherwise, cycling is typically performed manually. f Safety System Operator and test stand safety are assured through safe design and safety precautions. Hazardous equipment is guarded and gauges will have safety blow out plugs. Potential hazards are also clearly marked with proper safety and emergency procedures. Instrumentation The basic test stand incorporates analog pressures gauges. Instrumentation Type Range Accuracy Pressure 0-60 PSIG 0.25% F.S. Pressure 0-500 PSIG 0.25% F.S. Pressure 0-5000 PSIG 0.25% F.S. Pressure (damped) 0-15000PSIG Services & Key Physical Data Hydraulic Supply Type of fluid: Skydrol 500B-4 or other hydraulic fluid Reservoir Capacity: 10 Gallons Operating Temperature: Ambient Filtration: 3 micron Pneumatic Supply Pressure: 75-125 PSIG Temperature: Ambient Condition: Clean & Dry Electrical Power Voltage: 115 or 230 VAC Phase: 1 Hz: 50/60 Dimensions (approximate) Depth: 48" Width: 60" Height: 60"
