Abstract：The variation of centrifugal oil pump performance and the influence on the law of accounting fori mpellert rimmed arei nvestigatede xperimentallya ftert hei mpellersw ith differento utleta ngleo fb ladea re cut while handling water. The results show that the flow rates at best efficiency points reduce as the impellers are trimmed, the maximum efficiency of pump raises while the impeller diameter firstly trimmed to 205mm, and the larger the outlet angle of blade is, the greater the increase in the efficiency gets. The exponents of head ands haft-powera rrivea tt hec onstantsr espectivelya t shut-off points.T hee xponentso ff lowr ate,h ead, shaft- power ande fficiencyd iffer fromt hec urrent theoretical values atb este fficiencyp oints.
