Abstract

The invention provides a low-temperature and high-speed floating ring sealing test device for a rocket engine, which includes a casing, which includes a casing I, a casing II and a casing III; a stepped main shaft arranged inside the casing; The front floating ring seal assembly and the rear floating ring seal assembly; the front floating ring seal assembly and the rear floating ring seal assembly form a test chamber in the housing II. The low-temperature and high-speed floating ring sealing test device for a rocket engine according to the present invention has strong functionality, good compatibility, good performance at low temperature and high speed, and can carry out various low-temperature sealing tests of floating rings, which can verify the integrity of the floating ring assembly. The sealing performance can also be used to assess the rationality of the floating ring structure.

Description

Technical field [0001] The present invention relates to liquid rocket engine turbopump with a floating ring seal art applications, and more particularly relates to a multipurpose high speed cryogenic rocket engine test floating ring seal means applied to various liquid rocket engine ring floating seal assembly batch sampling test , the running tests and research trials. Background technique [0002] High-speed rotation of the turbine pump is an important component of the liquid rocket engine, floating ring seal assembly is the key member of the turbine pump, the floating ring seal reliability is the reliability of the base engine. In the low temperature and high speed conditions, the sealing performance and the operating pressure of the floating ring seal assembly, speed, and other factors floating ring gap. This floating ring seal test device can simulate the real operating conditions of the engine turbo pump, the inlet chamber may be sealed test pressure change and the low spee...
