Rotor for oil gear pump made from aluminium powder |
摘要 |
<p>In order to keep the losses of a pump caused by oil return flow between the gears and the housing as low as possible at high operating temperatures, the oil pump gears are manufactured from a powdered Al/Si alloy formed by spray compacting, to which approximately 30 weight percent pure aluminum powder is admixed, by pressing and subsequent sintering.</p> |
