A rotary ram compressor test system

Abstract

The invention discloses a rotary punching air compressor testing system comprising a power system, a torque-measuring apparatus, a speedup system, an air inlet system, an air exhaust system, a rotary punching air compressor test segment, an air discharging device, a vibration measuring device, an auxiliary system and a pneumatic parameter measuring and data collecting system; detailed performance test data of a rotary punching compression rotor which is a core part of a rotary punching air compressor can be obtained, wall surface static pressure can be measured dynamically, a flow field structure of a tip part of the rotary punching compression rotor can be obtained, and requirements for lubrication and safety in high speed conditions and requirements for starting in low speed conditions can be met.

Description

technical field

[0001] The invention relates to the field of gas turbines, in particular to a test system for a rotary ram compressor. Background technique

[0002] Gas turbine is a high-power, high-performance power machine that converts heat energy into mechanical energy with air and gas as the medium. It has developed rapidly in recent decades and has occupied an absolute dominant position in the field of military and civilian aeroengines. The application of energy and other aspects is also becoming more and more extensive, and has increasingly attracted the attention of countries all over the world. The industrial level of gas turbines has become a symbol of the advanced level of a country's industry. In the draft outline of my country's "Thirteenth Five-Year Plan", aero-engines and gas turbines rank first among the top 100 projects, reflecting the country's great importance to the gas turbine industry. The compressor is one of the core components of the gas turbine, w...

Embodiment Construction

[0047] The rotary ram compressor test system of the present invention is mainly composed of a power system, a torque measuring device 3, a speed-increasing system, an intake system, an exhaust system, a rotary ram compressor test section 7, a gas discharge device, a vibration measuring device, an auxiliary system, Pneumatic parameter measurement and data acquisition system. Such as figure 1 As shown, the DC motor 2 drives the shaft system to rotate, the I-level speed increaser 4 and the II-level speed increaser 5 increase the shaft speed, and the shaft speed is stabilized at the design speed through the speed controller 1, and the rotating shaft drives the rotary stamping compression rotor Spin at high speed. The air in the air intake room 13 enters the surge tank 9 through the flow tube 12 and the diffuser section 10. When starting, the air intake throttle valve 11 is controlled at a smaller valve position, and it is gradually opened as the speed increases. Its function is ...
