dc.description.abstractThis project investigates the pressure generation performance by using 3 extended spiral grooves bearing (SGB), first one called K10 (new) with 10 grooves, second one called K15 (new) with 15 grooves, third one called K15 (Alan) with 15 grooves. All of 3 SGB were operated with outflow rate 0.01L/min and 2 different film thickness of 0.1mm and 0.05mm at 7 different rotational speed (300rpm, 600rpm, 900rpm, 1200rpm, 1800rpm and 2100rpm) in an open system. The experimental performance of those 3 SGB need to be compared with each other. From the experiments with 2 different film thickness of 0.1mm and 0.05mm, the experimental differential pressure of K10 (new) and K15 (new) SGB achieves maximum positive value occurred at 600rpm, subsequently decreases to negative value, the experimental differential pressure of K15 (Alan) SGB achieves maximum positive value occurred at 1200rpm, subsequently decreases to lower positive value. One possible reason is that different spiral groove length may affect the performance of SGB. The spiral length of K15 (Alan) is almost twice than that of 2 other SGB. The geometries parameter of 3 SGB are shown in Table 3-1. Moreover, one error has been found, which Eddy current sensor is not suitable for setting up film thickness of those 3 SGB, which reason was given in Chapter 3.en_US
