Abstract

The utility model relates to a global dynamic balancing machine of a turbocharger used for detecting and repairing the global dynamic unbalance of the turbocharger, which is suitable for an explosive motor turbocharger manufacture to measure and repair the dynamic unbalance and research the characteristics of a gas compressor. The design proposal of the global dynamic balancing machine is as follows: mechanical and hydraulic structures are used to simulate loading conditions that the compressor casing end of the turbocharger presses fresh air into the combustion chamber of the motor at the inlet end of the turbocharger that is to be measured and the suction and extrusion ends of a turbo. Reliable data for the research of the characteristic curve of the gas compressor is provided by obtaining the outlet temperature Tk2, the inlet temperature tK1, the outlet pressure PK2 and the inlet pressure PK1 of a tested object in operating conditions. The outlet temperature Tk2, the inlet temperature tK1, the outlet pressure PK2 and the inlet pressure PK1 of the measured object are obtained by an inlet temperature sensor and a pressure transmitter arranged on the tube of an air-intake double-button flow meter as well as an outlet temperature sensor and a pressure transducer installed on an equalizing pipe. A manual control valve controls the outlet pressure of the compressor casing of the measure object and the flow rate of the tube of the air-intake double-button flow meter. So the parameter of the surge point of the characteristic curve of the gas compressor can be obtained for calculation in different operating conditions.
