Problems solved by technology

At present, the detection test for turbochargers mostly adopts the method of off-line sampling detection. The detection gas mainly used in this method is the compressed air output by the air pump. This method often cannot accurately simulate the actual practical working conditions of the turbocharger. The test results are also inconsistent with the output parameters of the turbocharger under real working conditions

Abstract

The invention relates to the technical field of supercharger detection, in particular to a supercharger working state inspection test method, which adopts a supercharger test bed for testing, and comprises the following steps: S1, carrying out early-stage preparation; S2, carrying out low-speed test run pipeline inspection; S3, adjusting the turbine air inlet pressure, and carrying out ignition; S4, establishing self-circulation; S5, collecting test data; and S6, carrying out cooling and shutdown,starting a fan, opening an air source deflation valve, a turbine air inlet valve and an air compressor deflation valve, closing a self-circulation valve, stopping the fan after the temperature of a turbine inlet is reduced to 60-70 DEG C, and cutting off lubricating oil supply after the fan is stopped. According to the scheme, the supercharger is directly connected to the supercharger test bed, the real working condition of the supercharger is simulated through the work of the supercharger test bed, under the condition, the detection result of the supercharger is closer to the real working result, and the collected data is more real and reliable.

Description

technical field [0001] The invention relates to the technical field of supercharger detection, in particular to a method for checking and testing the working state of a supercharger. Background technique [0002] Exhaust gas turbocharging is the most important and widely used technology to improve the power performance of automobile engines. The turbocharger is an essential component in exhaust gas turbocharging technology. The airtightness and functional testing of turbochargers is a main way to judge the quality of turbochargers. At present, the detection test of turbocharger mostly adopts the method of off-line sampling detection. The detection gas mainly used in this method is the compressed air output by the air pump. This method often cannot accurately simulate the actual practical working conditions of the turbocharger. The test results are also inconsistent with the output parameters of the turbocharger under real working conditions. Contents of the invention ...
