The invention provides a compressor outlet test section of a turbocharger performance test bench, which comprises a first flange and a second flange, and is characterized in that an inner straight pipe section, an electric heating layer and a cooler are installed between the first flange and the second flange, two ends of the cooler are respectively connected with an inlet water regulating valve and a return water regulating valve, a cavity is formed between the electric heating layer and the inner straight pipe section, the electric heating layer is electrically connected to a heating power supply, the heating power supply is connected to a controller through signals, the controller is connected to a first thermocouple, a static pressure tester, a total pressure tester, a second thermocouple, the inlet water regulating valve and the return water regulating valve through signals, the first thermocouple is located in the cavity, and the static pressure tester, the total pressure testerand the second thermocouple are located in the inner straight pipe section. The compressor outlet test section of the turbocharger performance test bench can prevent a gas at a compressor outlet to radiate heat to the surrounding environment, thereby effectively ensuring the outlet temperature of a compressor to be close to the temperature at a heat insulation state, and ensuring the authenticityof performance data of the compressor.
Description
Technical field [0001] The invention belongs to the field of electromechanical technology, and particularly relates to a compressor outlet test section of a turbocharger performance test bench. Background technique [0002] The development of turbocharging technology is becoming more and more mature. In the process of product research and development, well-known turbocharger companies at home and abroad have formed their own unique styles of turbocharger design theory and turbocharging technology R&D system, all adopting "predictive design" combined with "testing" The research and development method of "verification". Test verification is an indispensable and important link, and the authenticity and accuracy of test data in the process of test verification is extremely important. In the compressor performance test of the turbocharger, the error of the temperature measurement after the compressor after adiabatic compression has a great influence on the evaluation of the compresso...
