油泵和油马达等液压装置在产品出厂和型式试验中,往往都需要精确测定容积效率这一重要指标。根据定义有: ηv=q_e/q_0 100％ (1) 式中,ηv为容积效率(％);q_e为额定压力时排量(毫升/转);q_0为空载排量(毫升/转)。
Hydraulic devices such as oil pumps and oil motors often require an accurate measure of volumetric efficiency as an important indicator of product availability and type testing. According to the definition: ηv = q_e / q_0 100% (1) where ηv is the volumetric efficiency (%); q_e is the displacement at rated pressure (ml / rev); q_0 is the empty displacement (ml / rev).
