Abstract

The invention provides a turbosuperchager test bed combustion chamber with the adjustable outlet temperature. The combustion chamber comprises a front flange, a nozzle, an ignition rod, a flame barrel, a casing barrel, a flame barrel flange, a temperature adjusting mechanism, a mixing segment outer barrel and a rear flange; the flame barrel flange is fixedly arranged on the tail of the flame barrel, the flame barrel is sleeved with the casing barrel, one end is connected with the flame barrel flange, the other end makes contact with the front flange, one end of the mixing segment outer barrelis connected with the other side face of the flame barrel flange, and the other end of the mixing segment outer barrel makes contact with the rear flange. The position of the mixing segment outer barrel is provided with the temperature adjusting mechanism. According to the combustion chamber, the adjusting mechanism is added on an outlet of the combustion chamber, cold air is introduced through anadjusting disc, cold air and high temperature gas are mixed, and the temperature adjusting range of the combustion chamber outlet is widened.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, in particular to a combustion chamber of a turbocharger test bench with an adjustable outlet temperature. Background technique [0002] During the research and development of turbochargers, it is necessary to carry out tests such as compressor performance tests, turbine flow characteristics tests, and turbine efficiency tests. During the test, it is necessary to reduce the test temperature of the turbine inlet under certain working conditions. The conventional turbocharger test bench uses a single-tube combustion chamber. Due to factors such as fuel-air ratio and combustion efficiency, the combustion efficiency of the combustion chamber is low under non-design conditions. If the fuel supply of the combustion chamber is simply reduced, it cannot If the air flow rate is reduced to a minimum, the combustion state in the flame tube is not the design condition, and the combustion is unstab...
