Abstract: This paper presents the theoretical basis and structural characteristics of the type selection in designing oil slurry pump for catalytic cracking unit of a refining enterprise, as well as its operation after being put into use. In view of the large deviation of the operating conditions of the oil slurry pump from the design parameters, the pump was modified for localization, and the design parameters were further optimized. After the transformation, the pump has achieved good effects in energy saving and long-cycle operation. The above optimization and improvement measures are of certain significance for the type selection in designing oil slurry pumps.
