Embodiment Construction

[0059] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0060] The invention is a high-pressure high-purity nitrogen gas distribution device for a plume test platform, such as figure 1 As shown, a high-pressure high-purity nitrogen generation system 100 and a high-pressure high-purity nitrogen delivery system 200 are included. The high-pressure high-purity nitrogen generation system 100 is mainly used for producing high-pressure high-purity nitrogen and storing it, and nitrogen is produced by liquid nitrogen; the high-pressure high-purity nitrogen delivery system 200 is mainly used for nitrogen filtration, decompression and distribution.

[0061] Such as figure 1 As shown, the high-pressure high-purity nitrogen generation system 100 consists of a liquid nitrogen tank 101, a low-temperature liquid nitrogen supply hand valve 102, a liquid filter 103, a low-temperature liquid nitrogen exhaust hand valve 104,...

Abstract

The invention discloses a high-pressure and high-purity nitrogen distribution device for a plume test platform and an application method for the device. The device comprises a high-pressure and high-purity nitrogen generation system and a high-pressure and high-purity nitrogen conveying system, wherein the high-pressure and high-purity nitrogen generation system is used for manufacturing and storing high-pressure and high-purity nitrogen, and the nitrogen is produced by liquid nitrogen; and the high-pressure and high-purity nitrogen conveying system is used for filtering, decompressing and distributing the nitrogen. The nitrogen can be continuously supplied to the high-pressure and high-purity nitrogen distribution device for a long time; and furthermore, a system pipeline is arranged concentratively, so that an operator can operate the high-pressure and high-purity nitrogen distribution device conveniently, quickly and safely.

Description

technical field [0001] The invention belongs to the field of vacuum science and technology, and in particular relates to a gas distribution device for high-pressure, high-purity nitrogen required in satellite thermal vacuum tests and electric propulsion and chemical propulsion engine plume tests and an application method thereof. Background technique [0002] The "Vacuum Plume Effect Test System" (multifunctional plume test platform) of Beihang University is a multi-purpose test device, which is mainly used for aerospace attitude and orbit control engine plume test research, and also takes into account thermal vacuum tests such as satellites. Due to the variety of tests that can be carried out on the plume test platform, a nitrogen source is required for the test, and the nitrogen pressure required for different purposes is different, which leads to the complexity of the pipeline of the high-pressure and high-purity nitrogen gas distribution device and requires a lot of compo...
