离心泵具有成本低廉、维护简单、节能高效等优点,但是原油粘度对离心泵特性影响较大,在稠油生产中应用较少。选择水平中开式双级离心泵作为稠油外输的替代泵型,采取了改进外输工艺,改造泵前管路,增大叶片进口处的过流面积,提高泵的抗汽蚀能力等措施。达到了泵效稳定、减少维修费用,降低能耗的目标,设备利用率高,有效保障了泵站的生产运行。
Centrifugal pumps have the advantages of low cost, simple maintenance, energy saving and high efficiency, but the viscosity of crude oil has a great influence on the characteristics of centrifugal pumps, and is less used in heavy oil production. Select the level of open two-stage centrifugal pump as an alternative to the heavy oil pump, take the improvement of the transport process, the transformation of the pump before the pipeline to increase the flow of leaves at the entrance area, improve the anti-cavitation pump capacity Measures. Achieved a pump efficiency and stability, reduce maintenance costs and reduce energy consumption goals, equipment utilization, effective protection of the pumping station production and operation.
