Design and Testing of a Scroll Pump Efficiency

Abstract:

This research designed and tested the efficiency of a scroll pump. The fixed and orbiting scrolls mathematic models were used in designing and constructing the scroll pump. The coordinates of the curves along the fixed and orbiting scroll wraps were calculated by SCILAB 5.1 program. The scroll coefficient is 3.0 mm while discrepancy of starting roll angle is radian. The scroll pump was modeled by Solid Work program and manufactured by a CNC machine. The testing facilities were design and constructed under the Japanese Industrial Standards (JIS B 8301) and used 0.5 horsepower, 3 phase AC motor, and motor speeds were controlled by a frequency inverter. The test speeds of motor were 700, 800, 900, 1000 and 1,100 rpm. The results were displayed as the relationship between water flow rate and pressure head (Q-H Curve). The Q-H curves were highly sloped. The maximum efficiency of the scroll water pump were 67.56 % at the volume flow 20.46 L/min. and pressure head 11.48 psig
