TEST-BENCH FOR RESEARCHING INTO COMPRESSORS Russian patent published in 2005 - IPC

FIELD: the invention refers to compressor making and designed for using at trials of pivotal, centrifugal and diagonal compressors and also their combinations.

SUBSTANCE: the objective of proposed technical solution is throttling of a compressor under consideration on a test bench. The technical result is achieved on the test bench for researching into compressors which have a drive, a multiplier, a compressor under consideration at whose input a measuring collector and still-water chamber with leveling arrangement are installed and at the output - an air collector, a throttle arrangement and output piping. At that throttle arrangement is fulfilled in the form of a part of the output piping which has a collector. At that openings are fulfilled in the collector and connected with a hollow of output piping and the collector itself is connected with an adjustable source of feeding of the working body of high pressure.

EFFECT: ensures fluent soft changing of hydraulic resistance of the output circuit and in case of necessity or an emergency situation momentary decrease of hydraulic resistance of the output circuit.
