| S.U. HIGH PRESSURE PETROL PUMPS. V.CH.1. A.{Mr Adams} PUMP WITH CAST IRON CYLINDER CURVES SHEWING EFFECT OF QUENCHING RESISTANCE CURRENT CURVE. WITH RESISTANCE. Current through pump in Amps Make Break VOLTAGE CURVE. WITH RESISTANCE. P.D. between points. VOLTS Make Break WITHOUT RESISTANCE Current through pump in Amps Make Break P.D. BETWEEN POINTS VOLTS Break Make B. PUMP WITH STEEL CYLINDER NO QUENCH RESISTANCE VOLTAGE CURVE. P.D. between points. VOLTS Make Break CURRENT CURVE. Current through pump. Amps Make Break THESE CURVES WERE TAKEN FROM OSCILLOGRAMS PRODUCED WITH THE COSSOR MODEL 3813 OSCILLOGRAPH. CONNECTIONS WERE MADE DIRECT TO THE Y DEFLECTOR PLATES AND TO THE COILS IN PARALLEL. | ||
