Gas production and supercharging device

Abstract

The invention relates to a gas production and supercharging device which comprises a sealing tank (2), a gas outlet pipe (11), a supercharging container (14), a pressure sensor (13) and a microcomputer controller (9). A heating device (4) is arranged in the sealing tank (2) so as to heat a gas generation agent in the sealing tank (2). The gas outlet pipe (11) is connected with a gas outlet on theside wall of the sealing tank (2) and the supercharging container (14). The pressure sensor (13) is connected with the supercharging container (14) and the microcomputer controller (9) and is used formonitoring the pressure in the supercharging container (14) and transmitting pressure data to the microcomputer controller (9). The microcomputer controller (9) is connected with the heating device (4) in the sealing tank (2) and is used for comparing the received pressure data with a set pressure value to form a control command for controlling whether the heating device (4) works or not. The device is high in gas production efficiency and can be used for various fields needing gas supercharging.

Description

technical field [0001] The invention generally belongs to the field of controllable inflation technologies such as aircraft fuel tank pressurization and satellite cold air propulsion, and in particular relates to a gas generation pressurization device. Background technique [0002] In fuel-based aircraft engines, with the consumption of kerosene, the liquid level decreases, forming a certain vacuum area, and a certain pressure is required to continue the supply of fuel. Nowadays, the method of inflating high-pressure cylinders is commonly used, but the cylinders need Periodic testing takes up a large volume, and the use and maintenance of high-pressure gas is difficult. The use of high-pressure gas without heating is inefficient, which increases the weight of the system, and the introduction of a heating system increases the complexity of the system.

[0002] In fuel-based aircraft engines, with the consumption of kerosene, the liquid level decreases, forming a certain vacuum area, and a certain pressure is required to continue the supply of fuel. Nowadays, the method of inflating high-pressure cylinders is commonly used, but the cylinders need Regular inspection, large volume, difficult maintenance of high-pressure gas, low efficiency of high-pressure gas without heating, increasing the weight of the system, and the introduction of a heating system increases the complexity of the system

[0003] The chemical gas-generating supercharger is generally ignited by a gas generator that uses sodium azide as the main gas-generating drug. The reaction only produces nitrogen, and the gas production rate is only 40% to 50%, and the reaction cannot be stopped after the start. Restricted conditions of use of the gas generator

[0004] In the prior art, gas cylinder pressurization is mostly used. The structure of gas cylinder pressurization is simple, but it is difficult to maintain. It must be equipped with a special site for protection. It is not suitable for high-mobility pressurization sites, and some use self-pressurization systems. Supercharging, complex structure, cooling operation of the introduced gas is required, and the pipeline is complicated
