Abstract:

Because of the special operating conditions of the charging pump, its structure and performance are different from those of centrifugal pumps in common use. In this paper, based on the problems in use, various types of casings of charging pumps used in our oilfield are analyzed. It is considered that a single-volute charging pump has more troubles. The modified circular-casing centrifugal pump would be more suitable for the charging pump chosen as the triplex pump.
