(RESEARCH INTO THE POSSIBILITY OF EXTENDING THE OPERATING RANGE OF ELECTRIC SUBMERSIBLE PUMP UNITS. BENCH TEST RESULTS)
The paper presents the main provisions of the methodology developed at Gubkin Russian State University of Oil and Gas (National Research University) Department of Machines and Equipment of Oil and Gas Industry to determine the possibility of extending the operating range of characteristics of electrically driven vane pumps. According to the given technique in order to check possibility of expansion of the working part of the pump characteristic it is necessary to spend some series of bench hydrodynamic and life tests with definition of a degree (intensity) of degradation of pump characteristics in various working conditions, and then to compare the value of this indicator for these characteristics. The paper also presents the results of bench tests of two stage sizes of electrically driven vane pumps with rated flow of 60 and 500 m3 per day – ELN5-60 and ELN5A-500. Tests were conducted at synchronous speed of the electric motor shaft 3000 rpm. The test results confirmed the possibility of extending the operating characteristics for pump modules ELN5-60 with a floating stage assembly within the range of 0.2–1.25 of the optimum flow, and with a compression assembly up to 1.5 of the optimum flow. For the ELN5A-500 with floating stage assembly, the operating envelope can be extended from 0.4 to 1.25 optimum flow, with the compression assembly extending the right-hand boundary of the operating envelope to 1.5 optimum flow.
