Embodiment Construction

[0035] The nozzle automatic liquid flow test device provided by the present invention includes a liquid flow test bench 1 and a return water system 2; wherein:

[0036] Such as Figure 1-Figure 4 As shown, the liquid flow test bench 1 includes a frame 101, a measurement and control cabinet 102, a C-shaped support panel 112, and a plurality of test stations (preferably 4); wherein, the measurement and control cabinet 102 is installed on the side of the frame 101 for installing the system. This integrated installation structure is convenient for equipment maintenance; the C-shaped support panel 112 is installed on the frame 101, and the C-shaped structure is welded by stainless steel plates. After welding, the stress is released to make it waterproof and rust-proof And the advantages of high strength; each test station includes lifting cylinder 104, water guide tool 107, upper tool 108, lower tool 111, two sliders 110, two guide rails 109, two water pipes 106 and two hoses 114 ...

Abstract

The invention discloses an automatic liquid flow test device for a nozzle. The automatic liquid flow test device comprises a liquid flow test bed and a water return system mounted on one side of the liquid flow test bed, the liquid flow test bench comprises a frame, a measurement and control cabinet, a C-shaped support panel and a plurality of test stations. Each test station comprises a lifting cylinder, a water guide tool, an upper tool, a lower tool, two sliding blocks, two guide rails, two water pipes and two hoses; the lifting air cylinder is installed on the top of the C-shaped supporting panel, the guide rails are installed on the vertical face of the C-shaped supporting panel, the water guiding tool is installed on the two guide rails through two symmetrical sliding blocks respectively, and the water guiding tool can be driven by a piston rod of the lifting air cylinder to move up and down in the vertical direction. The lower end of a water outlet of the water guide tool is connected with an upper tool, and a lower tool is installed on the bottom face of the C-shaped supporting panel. A plurality of nozzle products are tested at the same time through the plurality of parallel test stations, so that the working efficiency is effectively improved, and the result accuracy is improved at the same time.

Description

technical field [0001] The invention belongs to the technical field of automatic liquid flow test and relates to an automatic liquid flow test device for nozzles. Background technique [0002] Nozzle products are an important part of aerospace attitude and orbit control engine products. Nozzle products become nozzle assembly products after completing the test in the form of a single part. The nozzle assembly can be assembled with other parts after multiple rounds of processes to form a complete Engine products. Therefore, the test efficiency of nozzle parts is a key factor affecting the test efficiency of engine products. The nozzle product is in the shape of a hollow cylinder, and there is currently no automatic liquid flow test device for nozzle products in the industry. [0003] The current traditional method is to manually take the products one by one, copy the product code, manually put the nozzle product into the test tool for water test, and then perform the reverse...
