| 6. delivery lines, in an effort to show the relative quality of the oil which is being forced to the bearings after the engine has had an opportunity to warm up slightly and finish the test period originally started the night before. These latter samples being designated as 5-B. Tabulating the samples and designations for the sake of convenience it will be noted that the following are : Sample 1-B. Drawn from delivery line after 1/2 hour of operation of the engine with B.W.P. Intake. Sample 2-B. Drawn from delivery line after 1/2 hour of operation of the engine with the conventional suction bell and screen assembly. Sample 3-B. Drawn from within 1/2 inch of the surface of the oil after settling or remaining idle for a period of 15 hours, pump inoperative. Sample 4-B. Drawn from the oil delivery lines 1/2 hour after starting up after the 15 hour settling period with B.W.P.Intake. Sample 5-B. Drawn from the oil delivery lines 1/2 hour after starting up after the 15 hour settling period with conventional suction bell and screen assembly. All of these samples were forwarded to the Detroit Testing Labor-atories for analysis as to sediment content, nature of sediment and water content. The following is a report rendered by the Detroit Testing Laboratory: SAMPLE No SEDIMENT WATER 1-B Faint Trace Only None 2-B .326% By Weight 11.2% By Weight. 3-B Faint Trace None 4-B Faint Trace None 5-B .314% 7.6% By Weight. | ||
