Submersible Electric Pump

Submersible electric pump units are connected by bolts. This paper uses finite element analysis method to simulate how the pump joint bolt behave when it transmit torque.In this paper, temperature method is adopted to simulate the bolt preload and axial deformation.It also used to analyse and calculate the limited value when submersible electric pump units transmit torque under different preload. All of this provide the designing of connecting bolt preload and construction with theoretical basis.

The paper reports a brief description of spacecraft operating conditions, the main reasons of heating and thermal gradient appearance and need to reassign the thermal energy. Active thermal control systems and their advantages are considered, spacecraft for which the use of this type of thermal control systems is a priority. The electric pumping unit is pointed as a key unit of active thermal control systems. The electric pump unit is considered from the as the electromechanical system, its key elements are pointed. A description of the preferred pump types is reported and the types of active thermal control systems are briefly discussed. The foreign and domestic operating experience of spacecraft electric pumping units, the features of their designs are considered, the most common types of key elements are determined. Based on the results of the review, it is concluded that the most relevant layout of the electric pump unit is a centrifugal electrical pump with a brushless DC motor and hydrodynamic bearings. It is also indicated that the electric pump unit is a product with a long lifetime, which complicates the task of monitoring the technical condition in order to prevent failure.

Parameter Monitoring

The multi-parameter measurement of submersible electric pump is an important part of monitoring data underground. The system measures the temperature, pressure, leakage current and vibration signals, which return through the power line carrier technology and data processing on the oil well. This article also focuses on the pressure sensor temperature compensation algorithm, using an anti-linear curve fitting to approximating, and effectively eliminates the error of silicon pressure sensor resulting from temperature changing. The system has brought about a striking effect in experiments of oil field.
