COMPRESSOR TEST METHOD AND INSTALLATION FOR TESTING Russian patent published in 2014 - IPC G01M15/00 

FIELD: machine building.

SUBSTANCE: group of inventions relates to compressor engineering and compressor testing installations, in particular, it is intended for use at testing of axial-flow, centrifugal and mixed flow compressors and their combinations, at using of adjustable engine drive. A gas turbine engine is used as a power drive, the compressor is rotated via a summing speeder, and the rotation mode is changed by the delivery of the part of the withdrawn compressed air to the gas turbine engine and/or conversion of the compressed air energy into the rotation energy and its transfer to the summing speeder. The compressed air energy can be converted into the rotation energy with the help of an additional turbine connected to the summing speeder and set on the withdrawal pipeline for compressed air of the compressor. The part of the withdrawn compressed air can be delivered to the gas turbine engine via a heat exchanger. A compressor testing installation comprises a supply pipeline with a damper, an additional turbine and a bypass pipeline with throttles set on it, it comprises a gas turbine engine as a power drive, a summing speeder - as a speeder, the bypass pipeline is connected to the supply and outlet pipelines, and the additional turbine is installed so that to be able to transfer the rotation to the summing speeder and is connected on the supply side to the outlet pipeline and on the withdrawal side - to the bypass pipeline by a branch pipe with a throttle, the gas turbine engine is connected to the damper and the supply pipeline. The compressor testing installation can be fitted by a bypass line with a heat exchanger set on the above bypass pipeline and can be fitted with throttles providing for connection-disconnection of the heat exchanger to/from the flow.

EFFECT: reduced energy demand and expanded functionality in terms of implementing compressor testing modes.
