Abstract

In the paper, the application of a pre-screwed wheel of centrifugal main oil pumps is observed. The pre-screwed wheel serves as a backup pump for the main impeller and creates a small head. In this case, the cavitations reserve of the main unit is significantly reduced. The increase of throughput capacity is due to two factors: a slight increase in pressure after the station, as well as a significant reduction in the pressure before the pumping station. The application of a pre-screwed wheel is proposed for the operative increase of a throughput capacity at a small value. Economical comparison of the following methods of increase of throughput capacity is made:
  1. (1)

    use of a frequency-controlled drive

     
  2. (2)

    use of anti-turbulent additives

     
  3. (3)

    reduction of the settings at the entrance of stations with the help of pre-screwed wheels

     
  4. (4)

    selective repair of sections

     
  5. (5)

    restoring the pipeline capacity on the basis of determining the actual remaining life of pipelines without selective repair of sections. It is considered that the application of a pre-screwed wheel is characterized by low economic costs and small time of implementation and this method is perspective in oil industry.
