Abstract

The present invention discloses a turbine test bed. The turbine test bed comprises a turbine test device and a data acquisition system; the turbine test device is provided with a first driving mechanism, a turbine test mechanism and a second driving mechanism which are distributed sequentially from top to bottom; and the turbine test mechanism is connected with the first driving mechanism and the second driving mechanism through a turbine mounting shaft. The test bed is simple in assembly and can be used for measuring the performance of a single turbine, a multistage turbine and a counter-rotating turbine in different fluid media, the servo performance of the turbines and influences on flow fields caused by the rotation of the turbines.

Description

technical field

[0001] The invention relates to the technical field of turbine testing, in particular to a turbine test bench. Background technique

[0002] At present, as an important fluid dynamic component, the turbine can rotate under the energy of fluid media such as air flow, water flow, and mud flow, and then convert the energy of the fluid into mechanical energy. Common turbines include turbine engines, water turbines, wind generators, turbodrill stators and rotors, etc., which are widely used in aerospace engineering, hydraulic power engineering, shipbuilding and automobile industry, oil drilling industry and other fields. Various influencing factors such as the precision of turbine machining and the selected material will affect the performance of the turbine, but the decisive factor affecting the performance of the turbine is the geometry of the turbine, including the radial size of the turbine, geometric parameters, The shape of the blade, the gap size of the bl...
