Abstract

The invention discloses a high speed turbine power test system with self-locking protection, comprising a turbine (12), a small size air compressor (1), lubrication sealing air-intaking cut-off valve (2), an oil mist lubrication device (3), a water pump (4), a pressure stabilization tank (5), a decompression valve (6), a water-intaking cut-off valve (7), a reclaiming pool (8), a high-speed power testing machine (9), a rotation speed sensor (10), a flexible coupler (11), an external gas source (13), an air-taking stop valve (14), an air flow meter (15), a firebox (16), an air-taking bypass valve (17) , a corresponding gas path connecting line, a corresponding water path connecting line and a corresponding oil path connecting line. The different on-off state combinations of the four valves of the self-protection device are corresponded to three self-locking protection modes. The high speed turbine power test system with self-locking protection can satisfy accuracy test of the power performance of the power turbine under a high speed working condition, can prevent the accidents of overspeed of the turbine and inflowing of the low speed bearing in the process of the test and can improve the reliability of the test system.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, and in particular relates to a high-speed turbine dynamometer test system with self-locking protection. Background technique [0002] In the development process of equipment power technology, turbocharger, as the main means to improve the power performance of diesel engine, has received more and more attention. In order to obtain good engine performance, shorten the development cycle, and save costs, it is an effective way to predict engine performance by using appropriate simulation methods to establish a simulation model of turbocharged diesel engine. However, in the process of model establishment, accurate data on the performance characteristics of the turbocharger compressor and the performance characteristics of the turbine need to be input into the simulation model as boundary conditions. If there are errors in the input of these parameters, it will seriously affect the accuracy ...

AI Technical Summary

Problems solved by technology

Due to the swirling flow at the turbine outlet, this method cannot accurately measure the turbine outlet temperature, resulting in severe distortion of the test data of turbine power and efficiency; at the same time, the turbine test performance will be affected by compressor surge and blockage, resulting in the measured turbine performance It can only cover a small part of the actual turbine characteristics and cannot fully reflect the complete performance of the turbine

The above methods have the disadvantages of poor test accuracy and narrow applicable range
