In this paper, the performance of centrifugal oil pump pumping different viscous liquids and effects of the viscous Squids on the pump performance are being systematically investigated. Based on the performance test, summarizing the rale of pump characteristic curves varying with the viscosity of ...
Centrifugal pumpCavitationExperimentNumerical calculationFront pump cavityperforationTo improve the cavitation performance of a centrifugal pump, the high-pressure liquid in the front pump cavity is introduced into the cavitation area on the back of the blade by perforated holes at the front cover of th...

Keeping the operation of an ESP inside the recommended pumping rate range poses the most severe restriction in the application of ESP equipment and should never be forgotten by users. A floating impeller centrifugal pump's operating modes are illustrated in Fig. 3.6, in which the ranges of up...
The transient behavior of the centrifugal pump with straight blades mainly comes from the rotation deceleration of im- peller, and has nothing to do with the fluid deceleration. The numerical simulations show that a large area backflow can be seen when the rotational speed decreases to zero due ...
The results show that the change trend of the pump performance and axial force acquired by numerical and experiment is similar. At rated operating point, the error of axial force between the numerical simulation and experimental measurements is less than 3%. This confirmed the feasibility of ...
To ensure the accuracy of the calculation results, constant calculate is used in centrifugal pump original model in the first place, considering the grid independence and compare the different of calculated value and experimental value.
