Abstract

The invention provides a device for leading out a sensor cable in an ultralow-temperature and high-pressure environment and an installation method thereof. The sealing performance is ensured through sealing of a low-temperature end and a normal-temperature end, so that the sensor is convenient and rapid to install and good in sealing performance, and an ultralow-temperature and high-pressure test can be carried out; meanwhile, the device can be reliably applied to measurement of sensor parameters in the ultralow-temperature high-pressure environment, the sensor cable can be reliably led out from the ultralow-temperature high-pressure environment through the device, and the sealing failure leakage phenomenon is avoided.

Description

technical field

[0001] The invention relates to a device for leading out sensor cables in an ultra-low temperature and high pressure environment and an installation method thereof, belonging to the field of ultra-low temperature technology. Background technique

[0002] The development of a liquid rocket engine requires a large number of ground component tests, and the excellent performance of the test bench plays a vital role in evaluating the product. The liquid rocket engine uses low-temperature liquid fuel and oxidant, and considering the safety of the test medium, liquid nitrogen (boiling point is -196°C) is usually used as the simulated medium for the test.

[0003] In order to accurately measure the performance parameters of the test product, during the ground test of liquid rocket engine components, an ultra-low temperature and high pressure environment is established inside the test device, and low temperature sensors (temperature sensor, vibration sensor, etc.) are...
