| Abstract | ||||
| A new modification technique to control the liquid leakage due to internal wearing of the gear pump casing at the suction side is investigated. The basis of amendment depends on loss compensation by applying a pressure force on the gear bearings towards the wear location. Volumetric efficiency, mechanical efficiency and overall efficiency were calculated versus flow rate, pressure and the rotational speed. The rotational speed was ranging between 1500-0 rpm, the output pressure was between 5-60 bar and the corresponding flow rate was ranging between 4-12 L/min. The results showed a very good improvement of the volumetric efficiency. Volumetric efficiency was increased from 54% to 80% at 1500 rpm. | ||||
