Automatic detection and cleaning system of redundant substance of liquid rocket engine pipeline

Abstract

The invention provides an automatic detection and cleaning system of a redundant substance of a liquid rocket engine pipeline. The system mainly comprises an ultrasonic cleaning device, a particulate matter detection device, a signal acqusition device and an industrial control computer, wherein the ultrasonic cleaning device comprises a liquid holding tank, a liquid inlet pipe, a cleaning tank, a liquid level meter, an ultrasonic generator, a drainage pipe and a liquid collection tank; the cleaning tank is communicated with the liquid holding tank through the liquid inlet pipe and is communicated with the liquid collection tank through the drainage pipe; the liquid level meter and the ultrasonic generator are positioned in the cleaning tank; the particulate matter detection device is communicated with the liquid collection tank; the signal acqusition device comprises a microprocessor, a communication module, a signal acqusition module and a relay module; the industrial control computer is used for transmitting a turn-on and turn-off control signal to the microprocessor through the communication module and receiving and displaying liquid level information and particle matter information.

Description

technical field [0001] The invention relates to an automatic detection and cleaning system for redundant objects in liquid rocket engine pipelines, and belongs to the technical field of redundant object control for aerospace products. Background technique [0002] Aerospace engines are propulsion devices for missiles, rockets, and spacecraft, and their reliability directly determines the performance and life of aerospace systems. Excess substances in the engine and its pipelines are one of the main reasons for affecting engine performance. On March 22, 1992, the first Australian star, which was a cooperation between my country and Australia, failed to ignite due to excess aluminum in the rocket and caused a huge aerospace accident. Therefore, my country has designated March 22 as China Aerospace Quality Day. [0003] The production and manufacture of the engine and its auxiliary structures involves many process steps. Various particles will be introduced in the process of ...
