AI Technical Summary

Problems solved by technology

When a backfire failure occurs, an instantaneous pressure shock will be generated in the intake pipe, which will cause damage to the sensors, actuators and other components in the pipeline
At present, similar shock simulation generators on the market are all igniting flammable and explosive gases such as propane to create instantaneous pressure shocks in a simple test detonation tube. The peak pressure is uncontrollable and the test data is inaccurate.

Abstract

The invention discloses a gas machine tempering simulation experiment device and a use method. The gas machine tempering simulation experiment device comprises a tempering simulation combustion tube, and the lower middle portion of the tempering simulation combustion tube is vertically communicated with a compensation telescopic air cylinder; the upper part of the tempering simulation combustion tube is connected with an electronic throttle valve sample piece, and an igniter and a first air pressure sensor are distributed in the tempering simulation combustion tube; the left end of the tempering simulation combustion tube is connected with a constant-pressure mixed gas supply assembly; a reciprocating plunger, a sliding block, a connecting rod and an adjustable driving rotary disc crank assembly are distributed in the compensation telescopic air cylinder. The device and the method have the advantages that the pressure peak value can be set, the detection result is accurate, the test repeatability is good, and the reliability is high.

Description

Technical field [0001] The present invention relates to the field of power mechanical test techniques, and more particularly to a gas machine temper simulation experimental device and method of use. Background technique [0002] The tempering, that is, pre-mixing the combustible gas is before entering the engine's combustion chamber, is a non-expected knocking in the intake pipeline, which is a common type of failure of the current single-point injection natural gas engine. When the tempering failure occurs, an instantaneous pressure impact is generated in the intake pipe, and the components such as sensors, actuators in the pipeline are damaged. At present, similar impact analog generators in the market are all flammable and explosive gases such as propanes to make transient pressure impacts in a simple test fuel-proof tube, and the pressure peak is uncontrollable. The test data is not accurate. [0003] The disclosure of the present invention is only used to assist in the under...
