Abstract

The invention relates to the technical field of oil transportation engineering of oil field surface, and belongs to a performance testing device and method for a screw pump. The invention comprises a testing device and a detecting device as well as corresponding methods. The device is used for single-phase or two-phase media simulating experiment and has functions of simply judging the performance of the screw pump and optimizing the rotation speed of the screw pump. According to the testing device and method, a research on the performance of the screw rod pump under the conditions of different rotation speed, inlet and outlet pressure difference of the pump, viscosity of crude oil, mass parts of conveyed medium gas and the like is carried out. The detection device is designed, comprises a sensor, a programmable logic controller (PLC), an upper computer and a variable frequency control cabinet, and is used for acquiring data of the screw pump; by adopting a relative error method of actual measurement rotation speed and optimized rotation speed, the condition of the performance of the screw pump is judged. According to the operation of the device, the semi-automation is realized, and the method for judging the performance condition of the screw pump is simple and convenient; meanwhile, by a negative feedback controlling method, the rotation speed of the screw pump is adjusted, so that the screw pump is positioned in an optimal operation state, and the service life of the pump is extended.

Description

technical field [0001] The invention relates to a performance testing device and method of a screw pump, belonging to the technical field of oil and gas ground gathering and transportation. Background technique [0002] In terms of performance testing of the screw pump, due to the single measurement factor of the screw pump performance test device, it is impossible to fully understand the performance of the screw pump under different operating conditions, so it is impossible to detect defects early and improve it, and computer simulation technology cannot replace the screw pump. Actual operation. [0003] In the process of parameter operation of the screw pump, it is necessary to scientifically and objectively understand the performance of the screw pump to reduce the probability of human judgment errors. Therefore, it is necessary to develop a simple and quick method to judge its performance and to understand its status in time; it is of great significance to optimize the ...
