subsurface pump meaning in English

井下泵

Development of anti - gas subsurface pump started compulsively with magnetic force
磁力强制开启防气泵的研制
The university of petroleum ( beijing ) thereby develops a simulation test device for hydraulic subsurface pump for gas and liquid two - phase flow
石油大学(北京)为此研制了一套气液两相流液压抽油泵模拟试验装置。
The investigation in the flow field particularly the miscible - phase flow field in a subsurface pump is the key to improvement of the performance of the pump
研究泵内流场尤其是混相流流场，是改善抽油泵性能的关键所在。
Besides , it is suggested that the diagnosis and analysis technique of the working conditions of the subsurface pump be further developed and improved to ensure the effective and reliable operation of oil pumping equipment
此外，建议进一步发展和完善玻璃钢抽油杆柱超深抽采油的井下泵工况诊断与分析技术，确保抽油设备高效可靠地运行。
The device consists of a single - phase flow test device , which can make a real simulation of the downhole working conditions and the flow of the liquid in the subsurface pump , and a miscible - phase flow test device , which can simulate various oil - gas ratios
这种装置由单相流试验装置和混相流试验装置构成，前者能比较真实地模拟井下的各种工况和抽油泵内液体的流动状态，后者可模拟不同的油气比。
