Remote device for leakage detection of ultrahigh-pressure helium

Abstract

The invention provides a remote device for the leakage detection of ultrahigh-pressure helium. The remote device comprises a helium source installation mechanism, a three-axis linear motion platform, a remote console, and a special test environment box body, a helium source is arranged in the helium source installation mechanism, a detection suction gun is arranged on the three-axis linear motion platform and can be driven to perform three-axis movement by the three-axis linear motion platform, programming is performed to control the three-axis linear motion platform to drive the detection suction gun to move in a remote manner and perform leakage point detection of the helium source, and the ultrahigh-pressure helium source installation mechanism and the three-axis linear motion platform are arranged in the special test environment box body. According to the remote device, remote control is employed, personnel can perform air-tightness detection of the ultrahigh-pressure helium source in a remote manner and do not need to be close to the ultrahigh-pressure helium source, and operation risks are avoided.

Description

technical field [0001] The invention belongs to a test device for a gas system, and in particular relates to a remote control device for ultra-high pressure helium gas leak detection, which is used for realizing automatic positioning and detection of multiple leak detection points on an ultra-high pressure helium gas source by means of remote control. Background technique [0002] The ultra-high pressure helium source is an indispensable key unit of the rocket servo system, and its working power is the most powerful except for the rocket engine. The high-pressure helium (60MPa) stored on the ultra-high pressure helium source during rocket flight is used as the primary energy source for the servo system, and the air-tight performance of the ultra-high pressure helium source plays a decisive role in the attitude control of the servo system and even the entire rocket. Therefore, the airtight performance of the ultra-high pressure helium gas source needs to be tested by means of...
