Embodiment Construction
[0032] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0033] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0034] Such as figure 1 and 2 As shown, the present invention includes a water storage tank 7, an upper water pipe 5, an auxiliary water tank 8, an upper water tank 1, a variable diameter return pipe 3 and a workpiece fixing tool;
[0035] A water pump 6 is installed in the water storage tank 7, and the water pump 6 communicates with the water inlet of the upper water pipe 5, and the water outlet of the upper water pipe 5 communicates with the water inlet of the auxiliary water tank 8;
[0036] The auxiliary water tank 8 is fixed on the side of the upper water tank 1, and is connected with the upper water tank 1 through a communication pipe 10;
[0037] The upper edge of the upper wat...

The invention provides an aero-engine fluid director novel test device comprising a water storage tank, upper water pipes, secondary water tanks, an upper water tank, a variable diameter water return pipe and a workpiece fixing tool. Water pumps are installed in the water storage tank. The water pumps are communicated with the secondary water tanks through the upper water pipes. The secondary water tanks are fixed in the side direction of the upper water tank and connected with the upper water tank through a communicating water pipe. An overflow groove is fixedly arranged at the upper edge of the upper water tank. The overflow groove is communicated with the water storage tank through water return pipes. The lower end of the upper water tank is fixedly provided with a conical surface of which the center is downward. The center of the conical surface is fixedly provided with a measurement outlet. Workpiece fixing members are arranged between the measurement water outlet and the variable diameter water return pipe. A flowmeter is fixedly arranged on the variable diameter water return pipe which is connected with the water storage tank. According to the aero-engine fluid director novel test device, recyclable water is used in the test process, water surface static speed is increased, the shape of the water outlet of the upper water tank is improved and two secondary water tanks with steady flow are additionally arranged so that test time is saved and precision of test data is guaranteed.
Description
technical field [0001] The invention belongs to the field of engine manufacturing, and in particular relates to a novel test device for an aeroengine deflector. Background technique [0002] The flow area of the aero-engine deflector is an important parameter to identify the performance of the aero-engine, which requires a high degree of precision in the equipment for measuring the flow area of the aero-engine deflector. [0003] The general aero-engine deflector water flow test device includes an upper water tank, a lower water tank, a hydraulic lifting device (a lifting platform, a small water tank), a water pump motor, an explosion-proof device, a control device, and a non-standard chuck for the test workpiece. [0004] The circulation area of the test piece is relatively large, so the upper water tank needs to be filled with 30 tons of water for each test, and the lower water tank must be filled with 20 tons of water. The whole system is relatively large. In orde...
