Problems solved by technology

[0003] At present, there are various types of turbine test benches at home and abroad, covering a wide range. Designing hydraulic turbine tests, aero-engine tests, automotive turbocharger tests, etc., all have strong professionalism and singleness. Although detailed Targeted test data, but not interchangeable, can not test the performance of different types of turbine parts, and use a single fluid, can only test the turbine under the condition of a single gas or liquid medium

Embodiment 1

[0037] The performance of a single turbine under different flow fields: select a suitable fluid pump as the fluid source, keep the upper motor 1 in a non-working state, use the lower motor 12 as the load motor, install a single turbine on the lower turbine installation shaft 26, and select different pump pressures , pump flow, and sensors with a specified range can test the performance of a single turbine in the flow field. This test mode is suitable for testing the performance of turbine components such as downhole power generation turbines for measurement while drilling and supercharged turbines for automobile engines.

Embodiment 2

[0039] The performance of multi-stage turbines under different flow fields: Keep the upper motor 1 in a non-working state, the lower motor 12 is used as a load motor, install a multi-stage turbine on the lower turbine installation shaft 26, and select different experimental parameters and specified range sensors , which can measure the performance test of multi-stage turbine in fluid. This test mode is suitable for testing the performance of single-stage turbodrill stator and rotor and multi-stage turbine stator and rotor. In fact, the performance of the multi-stage turbine stator and rotor is not a simple superposition of the performance of the single-stage turbine stator and rotor. There is mutual influence between the turbines of each stage, and its influence on the flow field is also different from that of the single-stage turbine. Using this turbine test bench can It is convenient to study the above effects.

Embodiment 3

[0041] Contra-rotating turbine: Both the upper motor 1 and the lower motor 12 are used as load motors. The two parts of the counter-rotating turbine are respectively installed on the upper turbine installation shaft 6 and the lower turbine installation shaft 26. Different fluid media and test parameters are selected to suitably match The range of sensors can test the hydrodynamic performance of the counter-rotating turbine.

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...
