【摘要】 本文介绍一种潜油(潜卤)电泵的配套设备—潜油电机的井下油压(P)、油温(H)和系统绝缘电阻(Ⅰ)的监测装置,以及构成装置的各环节工作原理和现场工业试验结果。实践表明,装有井下PHI监测装置的潜油(卤)电机,可大大提高其运行可靠性。更多还原

【Abstract】 In this paper a matching set of a submersible oil well ( sub-salt well ) pump unit, the monitoring device referring to the oil pressure (P ), oil temperature (H)and insulation resistance in system (I) at down-hole for the submersible pump motor is presented. And the operating principle of every section composing the monitoring device and its field test results are given also. It was shown in application that equipping the submersible oil well ( sub-salt well ) pump motor with PHI monitoring device at down-hole could increase its operating reliability greatly.更多还原
