The flow bench shall be calibrated for and capable of The flow measurement shall be accurate to flowing oil up to 5x0 pounds per hour (pph) at a fluid
16、 temperature of 95 to 100 degrees Fahrenheit (OF). within plus or minus (+) - 2 percent (%). 4.1.3 Pressure gage. The pressure gage shall be a suitable aircraft type, calibrated to 100 pounds per square inch gage (psig) and having an accuracy of f 1%. 4.1.4 Lines, fittings, and fixtures: a. Lines an
17、d fittings. Suitable aircraft-type lines and b. Fixtures. When required, suitable fixturing shall be used fittings shall be used. for parts, subassemblies, and assemblies being flow checked. NOTE: No restriction smaller than the inside diameter of the inlet port shall be allowed. 4 Provided by IHSNo

Before flow checking parts, subassemblies, and assemblies, the following precautions shall be observed: a. Check for residual magnetism. Magnetism shall not exceed b
19、. C. All assembly requirements, such as the installation of three (3) gauss. All oil holes, grooves, and passages shall be clean and free of burrs . O-rings and seals, correct bolt torques, and bearing pinch, shall be met. mandatory. The locking of bolts, nuts, etc. shall not be 5.2 Configuration. P
20、arts, subassemblies, and assemblies requiring a flow check shall be as specified in table I by part number and description. - 5.3 Flow rate, pressure, and temperature. Flow rate, pressure, and temperature requirements for parts, subassemblies, and assemblies requiring a flow check shall be as specif
21、ied in table I. The pressures listed in table I shall be considered as actual part, subassembly, and assembly inlet port pressure requirements. 5.4 Procedure. 5.4.1 Pressure gage location. The pressure gage (see 4.1.3) shall be located within 1 inch of the inlet port of the part, subassembly, or ass
22、embly being flow checked or on the fixture being used. 5.4.2 Flow readina. The flow reading shall be obtained under the conditions specified in table I. The part, subassembly, or assembly shall be verified to meet the specif ied flow requirements . 5.4.3 Flow check test. All parts, subassemblies, an
23、d assemblies shall be tested as follows: a. Determine the pressure drop across the inlet fixturing (section of line, fitting, or fixture after pressure gage). Increase the inlet pressure by the amount equal to the pressure drop ( P). Record the flow measured with the pressure specified in table I at
24、 the part, subassembly, or assembly. Alternately apply an oil pressure of 100 and zero psig to shock the lubrication system and to dislodge any contaminants in the feed lines. Repeat the shock cycle not less than five times . b. C. 5 Provided by IHSNot for ResaleNo reproduction or networking permitt
