Turbine supercharger property test platform with assistant braking system

Abstract

The invention is the test-bed for the turbocharger character with assistant brake assembly, which is a test-bed with turbocharger compressor character test, turbine performance test and self-circulation character test. It includes the electric heater, intake valve for out gas source, blast chamber, the assistant supercharger, the governor valve to adjust all kinds of test condition, the connecting conduits and sensors. The test-bed uses the compressing air input from the out air source, the turbo of turbocharger is drive by the high-temperature gas generated by the injection ignition burning and the electric heater heating, which is adjusted by the corresponding valves to test the turbocharger compressor character, turbine performance and self-circulation character state. Especially, in the turbo character test, the turbo work absorption is done by the assistant turbocharger, which compressor impeller of compressor has the greater absorption ability.

Description

technical field [0001] The invention relates to the field of power machinery performance testing, and is a test bench developed for turbocharger production plants or supercharger research units, which simultaneously has turbocharger compressor performance testing, turbine performance testing and self-circulation performance testing. Background technique [0002] The use of turbochargers has greatly improved the performance of the engine. In the research and development process of the supercharger, it is necessary to accurately measure the performance data of the supercharger compressor and turbine through the test, so as to improve the supercharger and meet the requirements of matching with the engine. The traditional turbocharger performance test bench is divided into compressor performance test bench and turbine performance test bench. Rotate the turbocharger, adjust the fuel injection amount, the air intake pressure to control the speed of the turbocharger, and measure t...

AI Technical Summary

Problems solved by technology

[0005] 1. The turbocharger compressor performance test bench and the turbine performance test bench are tested on different test benches, which increases the equipment investment in the early stage and the maintenance cost of the test bench in the later use process;

[0006] 2. During the test process of turbine performance, the compressor as a power consumption device has a small pressure difference between its inlet and outlet, and the work consumed by the compressor is mainly
