Copy to Rm{William Robotham - Chief Engineer}/Col. 1325 Rm{William Robotham - Chief Engineer}/GB.6/GT.14.3.41. COOLANT PUMP RIG. Here is our proposed program of tests. 1. Endurance test of original B.60 single bolt drive pump (L.O.P. EB.4207). It is proposed to run this pump with fan at 4200 F.R.P.M. until failure occurs. This will give us our yard stick. 2. Endurance test of improved pump (SCD.1398) with fan. The duration of this test will depend on the life obtained in test No.1 and on the fact that the Buick fan belt test is for 300 hours at 4000 crank F.P.M. It is obvious that pump life should exceed belt life by an appreciable amount. 3. Endurance test of Buick type pump (PL.433). The primary object of this test is to get a figure of merit for this pump. Future work on the rig will depend on the results obtained in the above tests. Rm{William Robotham - Chief Engineer}/GB. | ||
