离心泵是油田中使用数量最多、总装机容量最大和耗电量最多的设备,有的油田离心泵的耗电量可占到总耗电量的75%。因此,降低离心泵的耗电量,对提高油田开发中的经济效益和降低生产原油成本,有着重要意义。降低离心泵电耗的基本方法有两种: 一是提高离心泵的本身效率,降低泵内的无益损耗功率,使电动机输入给泵的功率尽可能多地变为泵的有效功率,或泵在相同有效功率的情况下,少消耗电动机的功率。二是提高泵的实际运行效率。这一点使用
Centrifugal pumps are the most widely used equipment in the field with the largest total installed capacity and the highest power consumption. Some oilfield centrifugal pumps consume 75% of the total power consumption. Therefore, reducing the power consumption of centrifugal pumps, to improve the economic benefits of oil field development and reduce the cost of producing crude oil, is of great significance. There are two basic ways to reduce the power consumption of a centrifugal pump. One is to increase the efficiency of the centrifugal pump itself and reduce the unwanted loss power in the pump, so that the power input to the pump by the motor becomes as much as possible the effective power of the pump, With the same effective power, less power is consumed by the motor. The second is to improve the pump’s actual operating efficiency. This use
