    Abstract：The data of performance curves of centrifugal pump are obtained when test is based on such medium as fresh water. However， its performance based on such medium as crude oil is greatly different from that based on water. In order to objectively reflect the performance of centrifugal pump based on crude oil medium， it is necessary to convert data of its performance curves based on fresh water. Such conversion can be carried out through two common methods：chart conversion method and formula calculation method. The chart conversion method has such characteristic as fast conversion speed and visual conversion process and it’s very easy for users to view the chart and make a simple calculation. However， accuracy will be a problem because of visual errors. In comparison， formula conversion method is more accurate and easy to be applied in computer programming. Data conversion is made and performance curves of centrifugal pump based on crude oil are drawn through the two methods， which can provide valuable reference for selection of centrifugal pumps based on other viscous liquids.
