Stand for testing of turbine compressors DIESEL ENGINES

摘要

The proposed technical solution relates to the testing technique, namely the means for testing turbochargers, mounting onto a motor, driven them into action. The problem of the proposed utility model is to improve the accuracy and effectiveness of the test on any load operation, by simulating the actual loading conditions experienced turbochargers, as well as expansion power range and range test turbochargers with enlarged diameter working compressor wheel and housing with cooling medium. The proposed stand for testing internal combustion turbochargers engines comprises communicated with the atmosphere air feeding tubes to the test TCR and discharging flue gases bypass U-shaped air supply pipe informing discharge pipe of the compressor to the inlet of the turbine test TCR system "hot" start turbine test TCR comprising a combustion chamber for combustion of hydrocarbon fuel, arranged in the branch of the bypass pipe to the turbine inlet nozzle turbocharger and provided with at least least one fuel injector, the system 'cold' start turbine test turbocharger comprising a compressor station connected output pressure port to the bypass air supply pipe to the inlet turbocharger turbine, means for controlling the parameters of the test TCR and stand control device comprising a control panel of TCR to the control unit comprising a software package, a control panel, controls arranged on the control panel member and said signal conversion means vypol cepts a controller, wherein the outputs of said means for controlling the test parameters of the TCR are connected to the control unit, and vozduhopodayushuyu, fuel and oil system, which carry out the operation of the stand. Output pressure port of the compressor station is provided with two steered vibrokompensatorom and bypass valves with adjustable pivoting flaps, one of which is closest to the compressor station is arranged to perform the function of emergency valve. The bypass air supply pipe in the area between its two branches is provided with a drain communicating with them branch, at the opposite end communicating with the atmosphere and provided with a controllable relief valve with an adjustable butterfly valve, wherein in each branch of the bypass pipe temperature compensator is installed. Branch bypass pipe communicated with a compressor TCR, further provided with a controllable relief valve with an adjustable butterfly valve, disposed between the temperature compensator of this branch and the place connecting the drain branching to the bypass conduit, and the branch of the bypass pipe, comprising a combustion chamber is further provided with a bypass conduit and the three controllable bypass rotary valve with adjustable flaps, of which one valve is disposed in the zone between the drain and the output branch pressurized th nozzle compressor station, a second valve disposed in the branch of the bypass pipe between the temperature compensator of this branch of the bypass pipe and the combustion chamber containing it, considering the direction of air flow from the compressor station, and a third valve disposed in the bypass conduit communicating with the branch bypass pipe before and after the third valve. Means for controlling the test parameters TCR further comprise air flow sensors, arranged in the branch of the bypass pipe, comprising a combustion chamber and before the air filter test turbocharger compressor and temperature sensors and air pressure in the outlet discharge port of the compressor station. The combustion chamber is further provided with an indicator and flame detector. stand control device further comprises a control box connected to the control panel through an internal bus "X2X" comprising an input terminal terminal, input and output systems, drives an output terminal and a terminal. signal conversion element means for controlling parameters is executed in a controller, entered in the control unit, the control box connected to the input of its input system to the output means of the control parameters of the test TCR and to the outputs of actuators, and controls are placed on the control panel include regulators, made, e.g., in the form of encoders actuator controlled butterfly valve controlled bypass valve is formed by a pneumatic compressor posts Technological provided with positioners mounted to electrically adjust the position of each of the valves and with the possibility of translation of each valve to the closed or open position. The utility model comprises: 1N ZP f-ly, of claim 4 ft. and 4-ly Fig.
