oil vapour jet pump 油轮用泵
oil-jet type of pump 喷油真空泵
Ti comprises electromagnetic valve, pressure regulating valve and oil jet pump.
它包含有电磁阀、调压阀、喷油泵。
Comparison between the oilwell jet pump and other artificial lifting equipment shows that the jet pump is more suitable for oil recovery from complicated Wells.
将采油喷射泵与其他人工举升采油设备进行的分析对比表明，喷射泵更适用于复杂油井的开采。
The inlet pressure of the jet pump can also be obtained by the pressure ratio, and it can be used for acquiring the productivity curve of an oil well.
这样，就可以计算出诊断喷射泵井工况所需要的压力比，流量比和泵效等工况参数，泵吸入口压力还可用来计算油井的产能曲线。
