Pipeline Transport Institute Develops Test Benches for Electric Drives

Date of publication: 05 November 2020

The Pipeline Transport Institute has developed test benches to test and adjust electric drives.

The test benches developed as part of the Research & Development works are designed for testing and adjusting electric drives manufactured by Tomsk Plant of Electric Drives (TOMZEL) (Tomsk, Transneft Western Siberia subsidiary).

Samples of two test benches were manufactures with a range of set and controlled torques from 2 to 65 kN·m and from 30 to 180 kN·m, which allows them to test electric drives with a torque rating at the drive shaft from 10,000 N·m to 180,000 N·m.

In contrast to existing analogues, the development ensures a complete check of the electric drives’ functions, as well as testing electric drives for both stop and control valves. In addition, the measurement of the torque directly at the drive shaft of the tested electric drive allows to conduct more accurate measurements, and the presence of the tested electric drive’s feedback allows to automate the process of its adjustment.    The test bench is controlled from the operator’s work place with the help of specialised software.

The test benches have successfully passed acceptance testing and are ready for the start of operation at TOMZEL site. Their use will ensure the high quality of the manufactured electric drives due to the most accurate emulation of the stop valves operation when adjusting electric drives, reduce the time for adjusting the electric drives by automating the adjusting and testing process, and also reduce the costs and repair time due to the unification of means, measurement and test methods. It is possible to use the test benches with the full-fledged emulation mode of the stop valves operation when performing research and development work on creating new types of electric drives.

For reference

The electric drives are designed for mechanisation and automation of pipeline valves and are widely used in technological processes of controlling oil and petroleum products pipelines. They provide prompt remote control of the flow rate and pressure of the process fluid transported via the pipeline, fast shutdown and resumption of pumping via the pipeline.
