| Abstract: | The paper Introduces the basic parameters of 250 trailer pump unit, elaborates its power transmission relationship in details, carries out the simulation tests of the engine＇ s plateau performance applied to the FST2E engine test bed, obtaines the da- ta of the engine at different altitudes, including power, fuel consumption rate and oil consumption, and generates the load character- istic curves of the engine by fitting. Quantitative analysis of the influence of engine power＇ s decrease on pump flow, head, efficiency is made, and the corresponding conclusions is drawn which can provide the theor eticol basis and data reference for the use of the pump unit and for the development of new type pump unit. |
