Stand for testing of turbine compressors DIESEL ENGINES

摘要

The invention relates to mechanical engineering, more specifically to a test stand for internal combustion engines and turbochargers can be used to create complex systems to test diesel engine turbochargers automotive vehicles timber industry. Solves the problem of the utility model is to provide an efficient, easy to use and relatively simple in execution of test bench for an internal combustion engine turbochargers. This should be realized the possibility of testing the most common types of turbochargers on the basic modes of operation for practical advice to restore and improve their performance. In addition to the above, it solves the problem of creating a system for automatic detection of the technical parameters of the test turbocharger in real time using modern measurement equipment and display equipment. This problem is solved in that in a stand for testing internal combustion turbochargers engines, comprising means for the hot test and control turbochargers parameters according to the utility model, the stand comprises a set of a housing tubes for supplying to the test turbocharger air and discharging exhaust gases, a removable bypass U -shaped channel connecting the compressor outlet pipe to the turbine inlet, and a combustion chamber for combustion of hydrocarbon fuel is disposed hydrochloric a branch of the bypass channel before the inlet of the turbine, the turbocharger launch system is adapted to spin the turbine air flow from the compressor side, the output fuel supply system is connected through a fuel regulator with the fuel injector in the combustion chamber, the output oil supply system is connected through an oil flow controller a channel for supplying oil to the bearing assembly of the turbocharger, and means for controlling parameters include a turbocharger rotor speed sensor, the sensors perature, pressure and flow rate of fuel and oil, gas and air path booth provided temperature sensors and fluid pressure at the inlet and outlet of the compressor and turbine, wherein the outputs of said sensors are connected via a multichannel amplifier with the control unit, which is part of the control panel. In addition, nozzles for supplying to the test air turbocharger and discharging flue gases and detachable circumferential U-shaped stand passage provided with quick-flanged with a set of fixing means and spacers for setting the operating position of turbochargers various manufacturers, a system cold start, formed as a nozzle disposed a bypass channel in the region of the combustion chamber and connected to the outlet side of the compressor, pressure sensors configured to generate elektriches one of the output signal simultaneously with the display of the pressure gauge, and a rotor speed sensor is aligned with the sensor vibrations of the turbocharger.
